How many zeroes (real or imaginary) does f ( x ) = x 2 + x − 2 have?
Answer:
2 real zeros at x = - 2 , x = 1
Step-by-step explanation:
f(x) = x² + x - 2
to find the zeros let f(x) = 0 , that is
x² + x - 2 = 0 ← in standard form
(x + 2)(x - 1) = 0 ← in factored form
equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x + 1 = 0 ⇒ x = - 1
there are 2 real zeros , x = - 2 and x = 1

Today, you are retiring. You have a total of R411 016 in retirement savings, and have the funds invested such that you expect to earn an average of 7,10% interest compounded monthly on this money, throughout your retirement years. You want to withdraw R2 500 at the beginning of every month, starting today. How long will it be until you run out of money?
Answer:
Step-by-step explanation:
To determine how long your retirement savings will last when withdrawing R2 500 at the beginning of every month, we need to use a financial formula called the future value of an annuity formula, which calculates the future value of a series of equal withdrawals made at regular intervals over a fixed period of time.
In this case, we want to calculate how many months it will take for your retirement savings to be depleted, given that you will be withdrawing R2 500 at the beginning of every month. The formula is:
n = [log(PMT/(PMT - r*PV))]/[log(1+r)]
where:
PMT = R2 500 (the regular payment you will make every month)
r = 7,10%/12 (the monthly interest rate, which is the annual rate of 7,10% divided by 12)
PV = R411 016 (the present value of your retirement savings)
Using the above values in the formula, we get:
n = [log(2500/(2500-((7.10%/12)*411016))))]/[log(1+(7.10%/12))]
n = 182.1
Therefore, it will take approximately 182.1 months, or 15.2 years, until you run out of money, assuming all other factors remain constant, and you withdraw R2 500 at the beginning of each month.
can y’all show that a x - 4 is a factor of the function f(x) = 2x^3 - 5x^2 - 11х - 4.
Answer:
To show that a x - 4 is a factor of the function f(x) = 2x^3 - 5x^2 - 11x - 4, we need to show that f(a x - 4) = 0 for all values of x.
We can use polynomial long division or synthetic division to divide f(x) by (a x - 4) and check if the remainder is zero. Here, we will use synthetic division:
4/a | 2 -5 -11 -4
| 8a 12a 4a-16
+------------------
2 8a-5 a-11 4a-20
The last term in the bottom row of the table is the remainder, which is 4a - 20. We can see that this remainder is equal to zero if a = 5.
Therefore, if we substitute x = (5/ax - 4) into the function f(x), we get:
f(a x - 4) = 2(5/ax - 4)^3 - 5(5/ax - 4)^2 - 11(5/ax - 4) - 4
Simplifying this expression, we get:
f(a x - 4) = 0
This means that a x - 4 is indeed a factor of the function f(x) = 2x^3 - 5x^2 - 11x - 4 when a = 5.
14. (Find LCM of) : ax² - (a² + ab)x+ a²b, bx² - (b² + bc)x + b²c and cx² - (c² + ac)x+ c²a
Answer:
Step-by-step explanation:
To find the LCM of the given expressions, we need to factor each expression completely and then find the product of the highest powers of all the factors.
ax² - (a² + ab)x + a²b can be factored as:
ax² - (a² + ab)x + a²b = a(x - b)(x - a)
bx² - (b² + bc)x + b²c can be factored as:
bx² - (b² + bc)x + b²c = b(x - c)(x - b)
cx² - (c² + ac)x + c²a can be factored as:
cx² - (c² + ac)x + c²a = c(x - a)(x - c)
Now, the LCM is the product of the highest powers of all the factors.
The highest power of a is a², the highest power of b is b², and the highest power of c is c². So, the LCM is:
LCM = a²b²c²(x - a)(x - b)(x - c)
Therefore, the LCM of ax² - (a² + ab)x + a²b, bx² - (b² + bc)x + b²c and cx² - (c² + ac)x + c²a is a²b²c²(x - a)(x - b)(x - c).

The trapezoid A’B’C’D is a dilation of the trapezoid ABCD. What is the scale factor of the dilation?
Simplify your answer and write it as a proper fraction, an improper fraction, or a whole number.
PLEASE LOOK AT PICTURE!!!!!!
All corresponding side lengths have a ratio of [tex]\frac{1}{3}$[/tex] or less, we can conclude that the scale factor of the dilation is less than or equal to [tex]\frac{1}{3}$[/tex]
How to find factor of dilation?We can use the distance formula to find the length of the sides of both quadrilaterals, and then find the ratio of corresponding side lengths to determine the scale factor of the dilation.
Let's start with the original quadrilateral ABCD. The length of AB is:
[tex]$\sqrt{(9 - (-3))^2 + (3 - 0)^2} = \sqrt{12^2 + 3^2} = \sqrt{153}$[/tex]
Similarly, the lengths of BC, CD, and DA are:
[tex]BC: $\sqrt{(9 - 9)^2 + (9 - 3)^2} = 6$[/tex]
[tex]CD: $\sqrt{(-3 - 9)^2 + (3 - 9)^2} = \sqrt{144 + 36} = \sqrt{180} = 6\sqrt{5}$[/tex]
[tex]DA: $\sqrt{(-3 - (-3))^2 + (3 - 0)^2} = 3$[/tex]
Now, let's find the corresponding side lengths of the dilated quadrilateral A'B'C'D'. The length of A'B' is:
[tex]$\sqrt{(3 - (-1))^2 + (1 - 0)^2} = \sqrt{16 + 1} = \sqrt{17}$[/tex]
Similarly, the lengths of B'C', C'D', and D'A' are:
[tex]B'C': $\sqrt{(3 - 3)^2 + (3 - 1)^2} = 2$[/tex]
[tex]C'D': $\sqrt{(-1 - 3)^2 + (1 - 3)^2} = \sqrt{16 + 4} = \sqrt{20} = 2\sqrt{5}$[/tex]
[tex]D'A': $\sqrt{(-1 - (-3))^2 + (1 - 0)^2} = \sqrt{4 + 1} = \sqrt{5}$[/tex]
Now we can find the ratio of corresponding side lengths:
[tex]$\frac{\text{length of A'B'}}{\text{length of AB}} = \frac{\sqrt{17}}{\sqrt{153}} = \frac{\sqrt{17} \cdot \sqrt{153}}{153} \approx 0.821$[/tex]
[tex]$\frac{\text{length of B'C'}}{\text{length of BC}} = \frac{2}{6} = \frac{1}{3}$[/tex]
[tex]$\frac{\text{length of C'D'}}{\text{length of CD}} = \frac{2\sqrt{5}}{6\sqrt{5}} = \frac{1}{3}$[/tex]
[tex]$\frac{\text{length of D'A'}}{\text{length of DA}} = \frac{\sqrt{5}}{3}$[/tex]
Since all corresponding side lengths have a ratio of [tex]\frac{1}{3}$[/tex] or less, we can conclude that the scale factor of the dilation is less than or equal to [tex]\frac{1}{3}$[/tex]. To find the exact scale factor, we can choose any two corresponding side lengths and take their ratio.

Acute Triangle:
A triangle is acute if the sum of the squares of the two shorter sides is greater than the square of the longest side. Since we already know that the right triangle has x = 10, we can choose a value for x that is less than 10 to form an acute triangle.
Let's take x = 9:
6² + 8² > 9²
36 + 64 > 81
100 > 81
Obtuse Triangle:
A triangle is obtuse if the sum of the squares of the two shorter sides is less than the square of the longest side. We can choose a value for x that is greater than 10 to form an obtuse triangle.

2. Suppose a consumer has $30 available to be divided between commodities A and B and the unit price of B is fixed at $3. What will be his demand equation for A if his utility function is U = 4XgXb?
The demand equation for commodity A is Xa = (4/10)Xb.
What is demand equation?A demand equation is a mathematical representation of the relationship between the quantity of a good or service that consumers are willing to buy and the various factors that influence that demand, such as price, income, and preferences.
In the given question,
To find the consumer's demand equation for A, we need to use the utility maximization rule, which states that a consumer will allocate their budget in such a way as to maximize their total utility subject to their budget constraint.
Let Xa be the quantity of commodity A and Xb be the quantity of commodity B. We know that the consumer has $30 to spend, so the budget constraint is:
3Xb + pXa = 30
where p is the price of commodity A. We also know the utility function:
U = 4XgXb
To maximize U subject to the budget constraint, we can use the Lagrangian method:
L = 4XgXb + λ(30 - 3Xb - pXa)
where λ is the Lagrange multiplier.
To find the demand equation for A, we need to take the partial derivative of L with respect to Xa and set it equal to zero:
∂L/∂Xa = -λp = 0
This gives us λ = 0, which we can substitute back into the Lagrangian equation to get:
L = 4XgXb + 0(30 - 3Xb - pXa)
L = 4XgXb
To find the demand equation for A, we need to take the partial derivative of L with respect to p and solve for Xa:
∂L/∂p = -4XgXb/Xa = -30/3
Xa = (4/10)Xb
So the demand equation for commodity A is Xa = (4/10)Xb.

Matt increased his typing speed from 32 to 38 words per minute. What is the percent of increase
Answer:
Matt's typing speed increased by 18.75%.
Step-by-step explanation:
To find the percent increase, we can use the following formula:
percent increase = (new value - old value) / old value x 100%
Using this formula, we can calculate the percent increase in Matt's typing speed as follows:
percent increase = (38 - 32) / 32 x 100%
percent increase = 6 / 32 x 100%
percent increase = 0.1875 x 100%

What is surface area?A solid object's surface area is a measurement of the total area that the surface of the object takes up.
The definition of arc length for one-dimensional curves and the definition of surface area for polyhedra (i.e., objects with flat polygonal faces), where the surface area is the sum of the areas of its faces, are both much simpler mathematical concepts than the definition of surface area when there are curved surfaces.
A smooth surface's surface area is determined using its representation as a parametric surface, such as a sphere.
This definition of surface area uses partial derivatives and double integration and is based on techniques used in infinitesimal calculus.
Henri Lebesgue and Hermann Minkowski at the turn of the century sought a general definition of surface area.
L × b = 300
b = 300 / L
b = 300 / 60 = 5
Hence, b equal for the top of the bookcase to have the correct area= 5 cm2.

Because the x2 term's coefficient is positive, the function will rise without equation bound as x approaches infinity or negative infinity. As a result, no horizontal asymptote exists.
What is equation?An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x + 3" equals the number "9".
The y-intercept of the equation y = (0,0) is the point on the line where it meets the y-axis and corresponds to the value of y when x equals 0. As a result, the equation y = 0's y-intercept is (0,0).
An equation's domain is the set of all possible values of x for which the equation is defined.
a) Because there are no constraints on the potential values of x, the domain of the equation y = x2 - 4x is all real integers.
b) The domain of the equation y = 1/(x-4) includes all real numbers except x = 4, which is undefined since division by zero is undefined.
c) Because the term within the square root must be non-negative, the domain of the equation y = sqrt(x-3)(x-4) is x >= 3.
As x approaches a specific value, the graph of the function approaches but never reaches vertical asymptotes. As the denominator of a rational function hits 0, they arise.
Because y = (x-3)(x-4) is not a rational function, it lacks vertical asymptotes.
A function's horizontal asymptote is a horizontal line that it approaches when x approaches infinity or negative infinity.
The dominant term in the formula as x gets extremely large or very tiny is x2, thus we can rewrite the equation as [tex]y = x2 - 7x + 12[/tex] .
Therefore, Because the x2 term's coefficient is positive, the function will rise without bound as x approaches infinity or negative infinity. As a result, no horizontal asymptote exists.

Write an equation to determine the length (l)(l)left parenthesis, l, right parenthesis of the rectangle.
The length of the rectangle is 10.5 units.
What is perimeter?
Perimeter is the distance of a two-dimensional shape. It is equal to the sum of the lengths of all the sides of the shape. The perimeter is measured in units, such as centimeters, meters, feet, or inches, depending on the unit of measurement used for the dimensions of the shape.
The perimeter of a rectangle is given by the formula:
P = 2l + 2w
where P is the perimeter, l is the length, and w is the width.
In this case, we know that the perimeter is 34 units, and the width is 6.5 units. So we can substitute these values into the formula and solve for the length:
34 = 2l + 2(6.5)
Simplifying, we get:
34 = 2l + 13
Subtracting 13 from both sides, we get:
21 = 2l
Dividing both sides by 2, we get:
l = 10.5
So the equation to determine the length of the rectangle is:
2l + 2w = P
Substituting the known values, we get:
2l + 2(6.5) = 34
Simplifying and solving for l, we get:
2l + 13 = 34
2l = 21
l = 10.5
Therefore, the length of the rectangle is 10.5 units.

Define slopeit represents the rate of change of y with respect to x, which is the amount by which y changes for every unit increase in x.
In this case, the slope is negative (-0.1), which means that as the number of minutes on hold (x) increases by 1 unit, the level of satisfaction (y) decreases by 0.1 units.
In other words, the longer a customer spends on hold, the lower their level of satisfaction is likely to be. The slope is a key parameter in the equation and provides valuable information about the relationship between the two variables.

Stanley wants to know how many students in his school enjoy watching talk shows on TV. He asks this question to all 24 students in his history class and finds that 55% of his classmates enjoy watching talk shows on TV. He claims that 55% of the school's student population would be expected to enjoy watching talk shows on TV. Is Stanley making a valid inference about his population? (1 point)
a
No, it is not a valid inference because he asked all 24 students in his history class instead of taking a sample from his math class
b
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school
c
Yes, it is a valid inference because his classmates make up a random sample of the students in the school

Answer:
There is 5% of the juice left.
Step-by-step explanation:
We know that originally, the container had 80 oz of orange juice, this is 100% in our case.
Then we can write a relation:
80 oz = 100%
Now there are 4 ounces left, in the same way as before, we can write this as:
4 oz = X%
We want to find X%
First, let's write our equations:
4 oz = X%
80 oz = 100%
We can take the quotient between these two equations to get:
(4oz/80oz) = (X%/100%)
We need to solve this for X%, then we get:
(4oz/80oz)*100% = X% = 5%
This means that 4 oz is 5% of the initial volume of the juice container.
Then we can conclude that there is 5% of the juice left.

As a result, the length of the hypotenuse AB is three times that of the side that is perpendicular to angle B, denoted by the symbol x.
what is length ?Length, which is typically expressed in units like meters, feet, or inches, is a measurement of an object's size or the separation between two locations. It alludes to the measurement of an object's longest dimension or the separation between two ends. The term "length" can also be used to describe the extent of a line or the linear separation between two locations, such as the length of a triangle's side, a road, or a length of rope. In geometry, length is a crucial mathematical notion that is used to gauge an object's size, shape, and location.
given
The length of the side directly across from the angle divided by the length of the hypotenuse is known as the sine of an angle. Here are the facts:
60° sine + (BC/AB)
Using sin 60°, whose value is 3/2, as an example:
√3/2 = (BC/AB)
Multiplying AB by both sides:
BC = AB * √3/2
The hypotenuse's length is determined by adding the squares of the lengths of the other two edges. Here are the facts:
We have the following by substituting the earlier-obtained formulas for AC and BC:
Adding 3 to both sides:
4AB2 + 9AB2 = 12AB2
AB = 3x
As a result, the length of the hypotenuse AB is three times that of the side that is perpendicular to angle B, denoted by the symbol x.
