Answer 1

Answer:

[tex]\textsf{a)} \quad y=3\left(\dfrac{5}{3}\right)^x[/tex]

[tex]\textsf{b)} \quad y=40\left(\dfrac{1}{3}\right)^x[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Function}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]

Question (a)

From inspection of the diagram, two points on the graph are:

(0, 3)(1, 5)

The y-intercept is the y-value when x = 0.

As a is the y-intercept, and the y-intercept is 3:

[tex]\implies y=3 \cdot b^x[/tex]

Substitute point (1, 5) into the equation and solve for b:

[tex]\begin{aligned}(1,5) \implies 5&=3 \cdot b^1\\5&=3b\\b&=\dfrac{5}{3}\end{aligned}[/tex]

Therefore, the equation of the exponential function is:

[tex]y=3\left(\dfrac{5}{3}\right)^x[/tex]

Question (b)

From inspection of the diagram, two points on the graph are:

(0, 40)(-1, 120)

The y-intercept is the y-value when x = 0.

As a is the y-intercept, and the y-intercept is 40:

[tex]\implies y=40 \cdot b^x[/tex]

Substitute point (-1, 120) into the equation and solve for b:

[tex]\begin{aligned}(-1,120) \implies 120&=40 \cdot b^{-1}\\\dfrac{120}{40}&=\dfrac{1}{b}\\b&=\dfrac{40}{120}\\ b&=\dfrac{1}{3}\end{aligned}[/tex]

Therefore, the equation of the exponential function is:

[tex]y=40\left(\dfrac{1}{3}\right)^x[/tex]

Answer: D

Step-by-step explanation:

The parent function abs(x) is a V, similar to graph B.

When it is multiplied by a negative number then it reflects across the Y axis, and if the number is greater than 1, then the graph is horizontally compressed (like you're squishing the sides together, closer to each other).  If the number is less than 1, either decimals or a fraction, then it is stretched (like you are pulling the sides away from each other and they are getting wider).  

In this case you are multiplying abs(x) by 4, which is greater than 1 so it is compressed by a factor of 4, and then multiplying it by a negative, which reflects it across the y axis.

Your redecorating your bedroom, and you want to put in a dressing table. The wall where you want to put it measures 4.7m. There is also a cupboard door on this wall, which takes up 410mm. The dressing table you like is 123cm wide. Once you've bought the dressing table , how much space on the wall, do you have left, not including the cupboard doors? I need this working out in metres please.

Answers

Answer:

3.06 meters

Step-by-step explanation:

The first thing you want to do, since we are working with different units here, is find out how many centimeters make a meter... and so on.

1cm = 0.01m

1mm = 0.001m

123cm = 1.23m (Dressing table)

410mm = 0.41m (Cupboard door)

Now all we need to do is subtract.

We can add the two numbers together or (If you prefer) subtract separately.

1.23 + 0.41 = 1.64

Now subtract that number from the measurement of the wall:

4.7 - 1.64 = 3.06

The amount of space left is 3.06m.

Is the sum of 3.04 and √20 rational or irrational? Explain.

Answers

Answer:

Irrational

Step-by-step explanation:

A rational number can be expressed as p/q where p and q are integers

3.04 is rational since it can be expressed as 304/100

√20 is not rational. √20 = √(4·5) = √4·√5 = 2√5
While 2 is a rational number, √5 is irrational since 5 is a prime number and square roots of primes are not rational

An irrational number multiplied by a rational number is irrational so √20 is irrational

An irrational number added to a rational number results in an irrational number.

So 3.04 + √20  is irrational

The radius of a cone is 2.5 units. The volume of the cone is 19 cubic units

Answers

The formula for the volume of a cone is given by the following equation:

V = 1/3 * π * r2 * h

where V is the volume of the cone, r is the radius of the cone, and h is the height of the cone.

In this case, we are given that the radius of the cone is 2.5 units and the volume of the cone is 19 cubic units. We can use this information to complete the expression that represents the height of the cone as follows:

V = 1/3 * π * r2 * h

19 cubic units = 1/3 * π * 2.5 units2 * h

19 cubic units = 1/3 * π * 6.25 units2 * h

19 cubic units = 1/3 * 19.63 units2 * h

19 cubic units = 6.54 units2 * h

h = 19 cubic units / 6.54 units2

h = 2.9 cubic units / 6.54 units

Therefore, the expression that represents the height of the cone is 2.9 cubic units / 6.54 units.

The perimeter of a triangle is 58 cm. The triangle is isosceles, but if its base were lengthened by 4 cm and each leg were shortened by 7 cm, then it would be equilateral. Find the base of the original

C. 23 cm
D. 16 cm

Answers

The base of the original triangle is 12 centimetres.

How to find the base of the original triangle?

A triangle is a polygon with three sides. The perimeter of a triangle is 58 cm. The triangle is isosceles.

An isosceles triangle is a triangle with 2 sides equal to each other and two angles equal to each other.

Therefore, let's find the base of the original triangle when the base were lengthened by 4 cm and each leg were shortened by 7 cm,

Hence,

let

x = length of legs

y = length of the base

Therefore,

2x + y = 58

Hence,

y + 4 = x - 7

x - y = 11

2x + y = 58

x - y = 11

3x = 69

x = 69 / 3

x = 23

-y  = 11 - 23

-y = -12

y = 12

Therefore,

base of the original triangle = 12 cm

282.6
306.6
565.2

Answers

Answer:

Volume = 282.6 ft.²

Step-by-step explanation:

Volume: V = πr²h

Step 1: The answer needs to be in cubic feet, so convert all units to feet

    1. 3 ft./12 in. = 0.25 ft.

Step 2: Subtract 0.5 ft from 6.5 ft to find the actual diameter of the pipe that the water will be passing through

    2. 6.5 ft. - 0.5 ft. = 6 ft.

Step 3: Plug 3 ft. (radius), 3.14 for π, and 5 ft for h

    3. V = (3.14)(3 ft.)²(5 ft.)

Step 4: Solve for the V (volume)

    4. V = (3.14)(9 ft.)(5 ft.) → V = (28.26)(5) → V = (28.26)(5) → V = 141.3 ft.²

Step 5: Divide 141.3 by 2, since we want half the capacity

    5. 141.3 ft.²/2 = 70.65 ft.²

Step 6: Multiply 70.65 by 4 since we want the total volume of water passing through four pipes

    6. 70.65 ft.² ∙ 4 = 282.6 ft.²

f(x)=1/2x+8 reflect x axis

Answers

The function of reflect x-axis is g(x) =  -(1/2)*x - 8, according to the question.

What do you mean by function?

A function in mathematics from a set X to a set Y assigns exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.

According to the given question,

First, let's define a reflection over the x-axis.

If we have a point (x, y) and we reflect it over the x-axis, our new point will be (x, -y).

Now, when we have a function

f(x) = y, the points can be written as:

(x, y = f(x) ) = (x, f(x))

Then, after the reflection over the x-axis, we have:

(x, y = g(x)) = (x, -f(x))

So now we have g(x) = -f(x)

and we know that f(x) = (1/2)*x + 8

then our new function is g(x) =  y = -f(x) = -( (1/2)*x + 8) = -(1/2)*x - 8.

g(x) =  -(1/2)*x - 8.

Therefore, the required answer is g(x) =  -(1/2)*x - 8.

First, we want to deal with the parenthesis within the parenthesis.

(4.6/2) = 2.3

Rewrite it into the equation.

[3 * 2.3] + 14.1 = ?

Now, do the work in the parenthesis again.

[6.9] + 14.1 = ?

to know if x + 7 is a factor, x = -7 when substituted should give 0 as a remainder otherwise it is not a factor.

By substituting x = -7 we have

[tex](-7)^{3}[/tex] [tex]-3(-7)^{2}[/tex] +2(-7) - 8 = -343 -147 -14 - 8  which is -512

Every day, Garrett's burrito stand uses 1 7/10 bags of tortillas. How many days will 8 1/2 bags of tortillas last?

Answers

Answer: 5 days.

Step-by-step explanation: To solve this problem, we first need to convert 1 7/10 bags of tortillas to a decimal number. We can do this by dividing the numerator of the fraction (7) by the denominator (10) and adding the result to the whole number (1) to get 1 + 7/10 = 1.7 bags of tortillas.

Next, we can divide the number of bags of tortillas that Garrett's burrito stand uses per day (1.7 bags) into the total number of bags of tortillas that are available (8.5 bags) to find out how many days the tortillas will last: 8.5 bags / 1.7 bags/day = 5 days

Answer:

linearadditivelycommon differenceabout 240.12

Step-by-step explanation:

Given the values in the table, you want to know if they represent a linear or exponential relation, along with the common difference or ratio, as applicable.

Changes

The first attachment shows the differences and ratios between successive table values. Neither the differences nor the ratios are constant. The wide variation in ratios and the relatively smaller variation in differences suggests the table is best modeled by a linear function.

Changes when the function is linear are additive. That is, the function values have a common difference.

Common difference

The average difference between table values is (949.92 -229.44)/3 = 240.16. A linear regression analysis gives a slope of 240.12 as the "best fit" to the table values.

You can see from the first attachment that the differences are not constant, so there isn't really a common difference. The difference is approximately 240.12.

__

Additional comment

The second attachment shows linear and an exponential regression applied to this data. The residuals are much smaller for the linear approximation.

The slope of the line (common difference) is estimated at 240.12 using the regression formula. This makes the mean square residuals a minimum. As we show above, this slope is different (slightly lower) than the slope of the line through the first and last data points.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

The system of equations:

y = -3x - 1

y = x² - 3x + 4

The solutions of the equation.

y = 0

So,

-3x - 1 = 0

x² - 3x + 4 = 0

It is in the form of ax² + bx + c = 0

a = 1, b = -3, and c = 4

Now,

x = -b ± √(b² - 4ac) / 4a

x = 3 ± √(9 - 16) / 4

x = 3 ±√-7 / 4

x = 3 ±i√7 / 4

What number represents 3,675,100,608 rounded to the nearest million?

Answers

The number 3,675,000,000 represents 3,675,100,608 rounded off to the nearest million.

Rounding off large numbers.

When we round off large numbers, we consider the digit to the right of the number occupying the place value for which we are rounding off to. If the digit to the right is 4 or less, we round down (we leave the number we are rounding to), but if the digit is 5 or higher, we round up (we increase the digit we are rounding by 1). and thus round to the indicated place value.

From the question, we have the large number;

3,675,100,608

the digit 5 indicates the place value (million)
