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
A primary credit card holder's card has an APR of 11.99%. The current monthly balance, before interest, is $7,568.19. The cardholder makes a payment of $350 the first 11 months and then pays off the balance at the end of the 12th month. How much interest did the credit card holder pay?
$720.27
$156.34
$370.31
$679.70
The credit card holder paid $720.27 in interest over the 12 months. Answer choice A, $720.27, is the correct answer.
What is simple interest?
Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.
First, let's calculate the monthly interest rate by dividing the APR by 12:
11.99% / 12 = 0.99917%
Next, let's calculate the interest paid on the monthly balance for each of the 11 months before the final payment:
Month 1:
Interest = $7,568.19 x 0.99917% = $75.59
Month 2:
Balance = $7,568.19 - $350 - $75.59 = $7,142.60
Interest = $7,142.60 x 0.99917% = $71.38
Month 3:
Balance = $7,142.60 - $350 - $71.38 = $6,721.82
Interest = $6,721.82 x 0.99917% = $67.11
Month 4-11: (follow the same process as above)
Interest for Month 4: $63.82
Interest for Month 5: $60.51
Interest for Month 6: $57.17
Interest for Month 7: $53.80
Interest for Month 8: $50.41
Interest for Month 9: $47.00
Interest for Month 10: $43.56
Interest for Month 11: $40.11
Now, at the end of month 11, the cardholder has a balance of:
$7,568.19 - ($350 x 11) - $75.59 - $71.38 - $67.11 - $63.82 - $60.51 - $57.17 - $53.80 - $50.41 - $47.00 - $43.56 - $40.11 = $1,225.74
Finally, the cardholder pays off the remaining balance of $1,225.74 at the end of month 12. The interest charged for this month would be:
Interest = $1,225.74 x 0.99917% = $12.25
So the total interest paid by the cardholder over the 12 months is:
$75.59 + $71.38 + $67.11 + $63.82 + $60.51 + $57.17 + $53.80 + $50.41 + $47.00 + $43.56 + $40.11 + $12.25 = $720.27
Therefore, the credit card holder paid $720.27 in interest over the 12 months. Answer choice A, $720.27, is the correct answer.

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%
percent increase = 18.75%
Rewrite the following equations in the form (x−p)2=q 0=x^2-18x+1 and the equation x^2+26x+167.5=0
For the first equation, we can complete the square to find its vertex form. Here's how we do it:
0 = x^2 - 18x + 1
0 = (x - 9)^2 - 80
So we have (x - 9)^2 = 80. This is in the form (x - p)^2 = q, where p = 9 and q = 80.
For the second equation, we can complete the square in a similar way:
x^2 + 26x + 167.5 = 0
x^2 + 26x = -167.5
x^2 + 26x + (26/2)^2 = -167.5 + (26/2)^2
(x + 13)^2 = 9.25
So we have (x + 13)^2 = 9.25. This is in the form (x - p)^2 = q, where p = -13 and q = 9.25.

Follow the steps below to find the value of x that makes A||B. offende 8x + 30 B 10x A Set the alternate exterior angles equal to each other. [ ? ]x = X + Enter
The value of x that makes A parallel to B is 15.
Describe Alternate Exterior Angles?Alternate exterior angles are a pair of angles that lie outside of two parallel lines and are on opposite sides of the transversal. In other words, they are a pair of non-adjacent angles that are formed when a transversal intersects two parallel lines. The angles are congruent, meaning that they have the same measure.
The term "alternate" refers to the fact that they are on opposite sides of the transversal and "exterior" indicates that they are outside of the parallel lines. Alternate exterior angles are important in geometry because they can be used to prove that two lines are parallel. If the alternate exterior angles are congruent, then the lines are parallel.
Since the alternate exterior angles are equal, we can set them equal to each other:
8x + 30 = 10x
Subtracting 8x from both sides, we get:
30 = 2x
Dividing both sides by 2, we get:
15 = x
So the value of x that makes A||B is 15.

By using chi-squared test, we can conclude that there is evidence of an association between breed and milk yield at the 5% significance level.
What is chi-squared test?
To perform a chi-squared test for independence between breed and milk yield, we need to set up the hypotheses:
Null hypothesis: There is no association between breed and milk yield.
Alternative hypothesis: There is an association between breed and milk yield.
We will use a significance level of 0.05.
To calculate the expected counts for each cell, we will use the formula: (row total x column total) / grand total.
The observed counts and expected counts are:
The grand total is 100.
The degrees of freedom for the test are (number of rows - 1) x (number of columns - 1) = (2 - 1) x (3 - 1) = 2.
Using a chi-squared distribution table or calculator, we find the critical value for a chi-squared test with 2 degrees of freedom and a 0.05 significance level to be 5.99.
To calculate the test statistic, we use the formula:
chi-squared = [tex]sum((observed\ count - expected\ count)^2 / expected\ count)[/tex]
The calculated value of chi-squared is:
[tex]chi-squared = ((32-25.76)^2 / 25.76) + ((20-19.04)^2 / 19.04) + ((16-13.20)^2 / 13.20) + ((10-16.24)^2 / 16.24) + ((18-18.96)^2 / 18.96) + ((4-4.80)^2 / 4.80) = 10.92[/tex]
The degrees of freedom for the test are 2, and the critical value is 5.99.
Since the calculated value of chi-squared (10.92) is greater than the critical value (5.99), we reject the null hypothesis.
Therefore, we can conclude that there is evidence of an association between breed and milk yield at the 5% significance level.

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.

Plot a point that best represents the value of square root 215 on the number line
Answer:
Put the point a tiny bit more than half way between 14 and 15.
Step-by-step explanation:
If you are allowed to use a calculator, put in sqrt215 and you get out 14.66, that goes a little bit more than halfway between 14 and 15.
If you are not allowed to use a calculator, think of the numbers on the numberline in terms of answers to *perfect square* questions.
So 12 is sqrt 144.
13 is sqrt 169.
14 is sqrt 196.
15 is sqrt 225.
So the 215 in your question is in between 196 and 225.
215 is closer to 225 (than to 196) so put the point closer to sqrt 225. That is, in between 14 and 15 and just a tad bit closer to 15.

Derrick invested some money at 2.25% simple interest and $1000 less than twice this amount at 1.5%. His total income from the interest was $510. How much was invested at each rate?
Derrick invested $23,306.28 at 2.25% and $462.79 at 1.5%.
What is percentage?
Percentage is a way of expressing a number as a fraction of 100. It is denoted by the symbol "%". For example, 50% means 50 out of 100 or 0.5 as a decimal.
Let's start by assigning variables to the unknown quantities in the problem. Let x be the amount Derrick invested at 2.25% and y be the amount he invested at 1.5%.
According to the problem, Derrick invested "1000 less than twice" the amount he invested at 2.25% at 1.5%. This means:
y = 2(0.0225x - 1000) = 0.045x - 2000
Now we can set up an equation based on the total income from the interest:
0.0225x + 0.015y = 510
Substituting the expression for y from the first equation, we get:
0.0225x + 0.015(0.045x - 2000) = 510
Simplifying and solving for x, we get:
0.0225x + 0.000675x - 30 = 510
0.023175x = 540
x = 23306.28
So Derrick invested approximately $23,306.28 at 2.25%. To find the amount he invested at 1.5%, we can substitute this value for x in the equation for y:
y = 0.045x - 2000 = 0.045(23306.28) - 2000 = 462.7856
So Derrick invested approximately $462.79 at 1.5%.
Therefore, Derrick invested $23,306.28 at 2.25% and $462.79 at 1.5%.

tails on the coin and an even number on the die?
There is a 1/4 or 25% chance that Jamal will end up with tails on the coin and an even number on the die when he rolls the die and tosses the coin.
The probability of rolling an even number on the die is 3/6 or 1/2, since there are three even numbers (2, 4, 6) out of the six possible outcomes. Similarly, the probability of getting tails on the coin is 1/2 since there are two possible outcomes, heads or tails. To find the probability of both events happening simultaneously, we need to multiply the probabilities of each event. Thus, the probability of getting tails on the coin and an even number on the die is:
P(tails and even) = P(tails) × P(even)
= 1/2 × 1/2
= 1/4

If μ (∠2) =98°, find the following angle measures.
Answer:
μ (∠1) = 82°
μ (∠2) = 98°
μ (∠3) = 82°
μ (∠4) = 98°
Step-by-step explanation:
As the vertically opposite angles are equal to each other,
μ (∠2) = μ (∠4)
98° = 98°
As the angles in a straight line are added up to 180°,
μ (∠2) + μ (∠3) = 180
98 + μ (∠3) = 180
μ (∠3) = 180 - 98
μ (∠3) = 82°
As the vertically opposite angles are equal to each other,
μ (∠3) = μ (∠1)
82° = 82°

We will use sine function, and length of the opposite side is [tex]\frac{25\sqrt{3}}{2}$[/tex] feet.
Explain about Sine function.To solve for the opposite side of the right triangle, we would use the sine function. In a right triangle, the sine of an angle is defined as the ratio of the length of the opposite side to the length of the hypotenuse.
In this problem, we are given that one angle of the right triangle is 60 degrees and the hypotenuse is 25 feet. Let's label the opposite side as x and the adjacent side as y. Then we can use the sine function:
[tex]$\sin 60^\circ = \frac{x}{25}$[/tex]
Simplifying the left side, we have:
[tex]$\frac{\sqrt{3}}{2} = \frac{x}{25}$[/tex]
Multiplying both sides by 25, we get:
[tex]$x = \frac{25\sqrt{3}}{2}$[/tex]
Therefore, the length of the opposite side is [tex]\frac{25\sqrt{3}}{2}$[/tex] feet.

Let S = {r, e, l, a, x} and T = {i, t, s, o, k, a, y}. Find n(S), n(T), n( ∪ ), and n( ∩ ).
The value of n (S) is 5, n (T) is 7, n (∪) is 11 and n (∩) is 1. The solution has been obtained by using the given sets.
What is a set?
Sets are represented as a collection of well-defined objects or elements and it does not change from person to person. A set is symbolised by a capital letter. The number of items in the finite set is known as the cardinal number of a set.
We are given two sets as S = {r, e, l, a, x} and T = {i, t, s, o, k, a, y}.
Now,
n (S) = 5
This is because there are 5 elements in this set.
n (T) = 7
This is because there are 7 elements in this set.
S ∪ T = {r, e, l, a, x, i, t, s, o, k, y}
n (∪) = 11
This is because there are 11 distinct elements in the sets.
S ∩ T = {a}
n (∩) = 1
This is because there is only 1 element common in the sets.
Hence, the required solution has been obtained.
