О 8a-48
O 2а
О 8а-6
O 48а

Answer:

40

Step-by-step explanation:

7 = 17.5% × Y

STEP 2 7 =

17.5

100

× Y

Multiplying both sides by 100 and dividing both sides of the equation by 17.5 we will arrive at:

STEP 3 Y = 7 ×

100

17.5

STEP 4 Y = 7 × 100 ÷ 17.5

STEP 5 Y = 40

Answer:

8 more times than

Step-by-step explanation:

We are told in the above question that:

Jason and Monica each need to put 1 gallon of water into a pot.

It is important to note that:

1 liquid gallon = 16 cups

1 liquid gallon = 8 liquid pints

For Jason

Jason has a measuring cup that holds 1 cup.

1 liquid gallon = 16 cups

In order to fill the pot, Jason has to use the cup 16 times

For Monica

Monica has a measuring cup that holds 1 pint.

Monica has to fill the pot using her measuring cup 8 times

How many more times does Jason need fill the measuring cup than Monica?

This is calculated as:

16 times - 8 times

= 8 times

Therefore, Jason needs to fill the measuring cup 8 more times than Monica

Answer:

1) The roots of the equation Y = -x² - 12·x - 37 are x = -6 - √73 and -6 + √73

2) The factors of the function Y = -x² - 12·x - 37 are (x + (-6 - √73)) and (x - (-6 + √73))

3) The vertex is (-6, -1)

4) The Y-intercept is (0, -37)

5) The axis of symmetry is x = -6

6) The parabola opens downward

7) The maximum point is (-6, -1)

8) The graph of the function created with Microsoft Excel is attached

9) The domain of the function is -∞ < x < ∞

10) The range of the function is -∞ < Y ≤ -1

Step-by-step explanation:

The given function is Y = -x² - 12·x - 37

1) The roots of the equation Y = -x² - 12·x - 37 is given as follows;

0 = -x² - 12·x - 37

∴ -x² - 12·x - 37 = 0

The roots are;

x = (12 ± √((-12)² - 4 × 1 × (-37)))/(-2)

∴ x = -6 - √73 and -6 + √73

2) The factors are (x + (-6 - √73)) and (x - (-6 + √73))

3) The vertex is given by h = -b/(2·a) = 12/(2) = -6

k = c - b²/(4·a) = -37 - 144/(-4) = -1

The vertex = (h, k) = (-6, -1)

4) The intercept with the "Y" axis is given when x = 0, therefore, the y-intercept is (0, -37)

5) The axis of symmetry can be found at the vertex or the line x = -6

6) The sign of the coefficient of x² is negative therefore, the parabola opens downward

7) The maximum point is given as follows;

At the maximum point, dY/dx = d(-x² - 12·x - 37)/dx = -2·x - 12 = 0

x = 12/(-2) = -6, which is the vertex, therefore Y = -(-6)² - 12×(-6) - 37 = -1

The maximum point is the vertex (-6, -1)

8) Please find attached the graph of the function created with Microsoft Excel

9) The domain of the function is -∞ < x < ∞

10) The range of the function is -∞ < Y ≤ -1

Answer:

The answer is below

Step-by-step explanation:

The question is not complete but i would show how to solve.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are dilation, rotation, translation and reflection.

Dilation is the enlargement or reduction in the size of a figure.

a) If an point A(x, y) is dilated by a factor k, the new coordinate is A'(kx, ky). From the above options the ones that represent dilation is (x, y) → (0.5x, 0.5y)  and (x, y) → (2x, 2y) . If the object is reduced then the correct option is (x, y) → (0.5x, 0.5y)   while if the object is enlarged the correct option is (x, y) → (0.5x, 0.5y)

b)Dilation is the enlargement or reduction in the size of a figure by a factor k. If k < 1, then it is a reduction and if k > 1, it is an enlargement.

Since Triangle XYZ is dilated with the origin as the center of dilation using the rule (x, y)⇒(0.5x, 0.5y) to create Triangle X’Y’Z’, since the factor is less than 1(0.5 < 1), it is a reduction. Hence Triangle X’Y’Z’ is smaller than Triangle XYZ, because the scale factor is less than 1

c) The dilation creates a smaller figure hence the factor of dilation should be less than 1.

Answer:

(- 1, - 9 )

Step-by-step explanation:

Under a counterclockwise rotation about the origin of 90°

a point (x, y ) → (- y, x ) , so

(- 9, 1 ) → (- 1, - 9 )

The image of the point (-9, 1) after a rotation of 90° counterclockwise about the origin is (1, 9).

Here are the rotation rules: 90° clockwise rotation: (x, y) becomes (y, -x) 90° counterclockwise rotation: (x, y) becomes (-y, x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y).

The given coordinate point is (-9, 1).

Rule: (x, y)→(y, -x)

The image of the point (-9, 1) is

(-9, 1)→(1, 9)

Therefore, the image of the point (-9, 1) after a rotation of 90° counterclockwise about the origin is (1, 9).

Answer:

We conclude that

(g o f) (4) = 9

Hence, option C is correct.

Step-by-step explanation:

Given

f(x) = -x³

g(x) = |1/8x - 1|

To determine

(g o f) (4) = ?

Using the formula

(g o f) (4) = g[(f(4)]

first we need to determine f(4)

so substituting x = 4 into f(x) = -x³

f(x) = -x³

f(4) = -(4)³ = -64

so

(g o f) (4) = g[(f(4)] = g(-64)

so substitute x = -64 in g(x) = |1/8x - 1|

[tex]g\left(x\right)=\left|\frac{1}{8}x-1\right|[/tex]

substitute x = -64

[tex]g\left(-64\right)=\left|\frac{1}{8}\left(-64\right)-1\right|[/tex]

            [tex]=\left|-\frac{1}{8}\cdot \:64-1\right|[/tex]

            [tex]=\left|-8-1\right|[/tex]

            [tex]=\left|-9\right|[/tex]

Apply absolute rule: |-a| = a

            [tex]=9[/tex]

Therefore, we conclude that

(g o f) (4) = 9

Hence, option C is correct.

Answer:

2x+15=33

Step-by-step explanation:

Computation of the equation that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day

Based on the information given the EQUATION will be :

2x+15=33

Where,

x represent Jerry Sit up numbers of days excluding the first day

2x represent the additional 2 more sit ups

2x +15 represent the total number of sit up that was done after the first day

2x+15=33 represent the total 33 sit-ups that jerry did today

Therefore the EQUATION that could be solved to find the number of days Jerry has been doing sit-ups, not counting the first day will be 2x+15=33

Answer:

45

Step-by-step explanation:

The formula for finding the longest size of a right angle is

[tex]c^{2} = a^{2} + {b}^{2}[/tex]

a = 28, b = ? and c = 53;

Therefore, if you make b the subject of the formula, you will have

[tex]b = \sqrt{ {c}^{2} - {a}^{2} } [/tex]

And after plugging the value of c=53 and a=28, b is gotten to be 45

Answer:

84dog cubes

Step-by-step explanation:

First we need to get the volume of the rectangular prism and the little cubes

Volume of the prism = base area × height

Volume f the prism = length × width × height

Given

Length = 7/4in

Width = 9/4in

Height = 3in

Volume of the prism = 7/4×9/4×3

Volume of the prism = 63/48

Volume of the prism= 21/16 in³

Volume of the cube = L³

L is the length of one side of the cube

Volume of the cube =(1/4)³

Volume of tje cube = 1/64in³

Number of dog food cubes that will fit in = 21/16÷1/64

= 21/16×64/1

= 21×4

= 84

Hence 84 dog cubes will fit in

Answer:

[tex]12 * (2 - 3) + (4 * 2)[/tex]

Step-by-step explanation:

Follow PEMDAS for the given answer.

PEMDAS is the order of operation, and is:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

Reverse solve the answer so that the result is the question.

First, solve the parenthesis:

12 * (2 - 3) + (4 * 2)

12 * (-1) + 8

Next, multiply 12 and -1 together:

12 * -1 = -12

Finally, add:

-12 + 8 = -4

12 * (2 - 3) + (4 * 2) is your answer.

[tex]12 \times (2 - 3) + (4 \times 2)[/tex]

Step-by-step explanation:

Add parentheses to the following equation to make it true.

[tex]12 \times 2 - 3 + 4 \times 2 = - 4[/tex]

[tex] = 12 \times 2 - 3 + 4 \times 2 = - 4[/tex]

[tex] = 12 \times (2 - 3) + (4 \times 2)[/tex]

[tex] = 12 \times ( - 1) + 8[/tex]

[tex] = - 12 + 8[/tex]

[tex] = - 4[/tex]

12w + 140 = 356

Step-by-step explanation:

Her goal is to save up 356$. She already has 140$, and wants to save 12$ per week. We're trying to find how many weeks it would take.

You must multiply 12 by the number of weeks, which elimates the first two equations. We're also trying to add together 140 and the 12x because we want the total to ADD to 156.
