Which Of These Is The Standard Form Of The Following Function?f(x) = -9(x + 5)2 + 4f(x) = -9x2 - 90x

Answers

Answer 1

Answer:

A

Step-by-step explanation:

Given

f(x) = - 9(x + 5)² + 4 ← expand parenthesis using FOIL

     = - 9(x² + 10x + 25) + 4 ← distribute parenthesis by - 9

     = - 9x² - 90x - 225 + 4 ← collect like terms

     = - 9x² - 90x - 221 ← in standard form

Find the constant of proportionality (r) in the equation y=rx

Answer:

The constant of proportionality is 75/58 or 1.29

Step-by-step explanation:

Given

The table above

Required

Find the constant of proportionality

The question has an incomplete table but it can still be solved because x and y are proportional.

Given that

y = rx

Make r the subject of formula

Divide through by x

y/x = rx

y/x = r

r = y/x

When y = 7.5, x = 5.8

Substitute these values

r = y/x becomes

r = 7.5/5.8

Multiply denominator and numerator by 10

r = (7.5 * 10)/(5.8 * 10)

r = 75/58

In this case, it's best to leave the answer in fraction.

However, it can be solved further.

r = 75/58

r = 1.29 (Approximated)

Hence, the constant of proportionality is 75/58 or 1.29

Answer:

the correct answer is 1

PPLLLZZZ HEEELPP WILL MARKK BRAINLESTTT!!!! PLEASE HURRY



Car A

y = 55x + 32


Car B

y = 42x + 58

After how many hours will the two cars be at the same distance from their starting point and what will that distance be?

2 hours, 142 miles

2 hours, 145 miles

3 hours, 142 miles

3 hours, 145 miles

Answers

Answer:

2 hours, 142 miles

Step-by-step explanation:

Given;

equation of motion of car A as;

y = 55x + 32

equation of motion of car B as;

y = 42x + 58

where;

y is distance measured in miles

x is time measured in hours

When the distance of the two cars are equal, we will have the following equation;

55x + 32 = 42x + 58

collect like terms and solve for x

55x - 42x = 58 - 32

13x = 26

x = 26 /13

x = 2 hours ( x is time measured in hours)

Now substitute in the value of x into any equation of the cars;

y = 55x + 32

y = 55 (2) + 32

y = 110 + 32

y = 142 miles ( y is distance measured in miles)

Thus, the correct option is 2 hours, 142 miles

The regional manager of a chain of department stores created the following stem and leaf plot showing the number of pairs of glasses at each of the stores how many department stores have exactly 37 pairs of glasses

Answers

Answer:

The stem and leaf plot is not shown, so I will answer the question in a general way.

Suppose you have the following stem and leaf plot

I 2 I 0 5 8

I 3 I 4 4 7 8

I 4 I 0

Then, the data is: 20, 25, 28, 34, 34, 37, 38, 40. In consequence, one department stores has exactly 37 pairs of glasses. But if your stem and leaf plot is:

I 2 I 0 5 8

I 3 I 7 7 7 8

I 4 I 0

then, three department stores have 37 pairs of glasses, and none of them have 34 pairs of glasses.

5+5=10 x 2 = 20

perimeter is 20

Hope this helps

Step-by-step explanation:

The perimeter of the given square is 20 inches.

What is the perimeter of the square?

The perimeter of a square is defined as the addition of the lengths of the square.

The perimeter of a square = 4a

Where a is the length of the side of the square

Given that the area of the square is 25 square inches.

Let a is the length of the side of the square

The area of the square = a² = 25

So a = 5

Since all sides of a square are equal, we can calculate the perimeter by multiplying the length of one side by 4:

The perimeter of a square = 4a

The perimeter of a square = 4(5)

The perimeter of a square = 20 inches

Therefore, the perimeter of the square is 20 inches.

Answers

Answer: 617 ft.

Step-by-step explanation: So first, the formula is A=C²/ 4π, knowing this, let's just plug in our numbers

A = C² /  4 · π

A = 88² /  4 · 3.14

A = 7744 /  4 · 3.14

A = 7744 /  12.56

A = 7744 /  12.56

Meghan needs to board her cats and dogs at a kennel while she is on vacation. Pet Hotel charges $42.50 for a cat and $64.00 for a dog for a total cost of $277.00. Animal Spa charges $35.50 for a cat and $50.50 for a dog, for a total cost of $222.50.

Write a system of equations to represent each charge. Let x represent the number of cats and let y represent the number of dogs.

Pet Hotel: ?
Animal Spa: ?

Answers

Answer:

Pet Hotel: 42.50 x + 64 y =277

Animal Spa: 35.50x + 50.5y = 225.50

Step-by-step explanation:

Hi, to answer this question we have to write an equation for each place:

For Pet Hotel, the total cost (277) must be equal to the product of the number of cats (x) and the charge per cat (42.50) plus the product of the number of dogs (y) and the charge per dog (64) .

Mathematically speaking:

Pet hotel: 42.5 x + 64 y =277

Same process for Animal Spa:

Animal Spa: 35.5 x + 50.5y = 225.50

The system is:

42.5 x + 64 y =277 (Pet Hotel)

35.5 x + 50.5y = 225.50 (Animal Spa)

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a diameter of 26 feet and a height of 14 feet. Container B has a diameter of 18 feet and a height of 15 feet. Container A is full of water and the water is pumped into Container B until Conainter B is completely full. After the pumping is complete, what is the volume of the empty space inside Container A

Answers

Answer:

First, let's work out the V of container A and B

V_A = pi x (diameter/2)^2 x height = pi x (26/2)^2 x 14 = 2366 pi (ft3)

V_B = pi x (diameter/2)^2 x height = pi x (18/2)^2 x 15 = 1215 pi (ft3)

After pumping water from container A to container B until B is full:

The empty space inside container A would be:

V_empty = V_A - V_B = 2366 pi (ft3) - 1215 pi (ft3) = 1151 pi (ft3) = ~3615.97 (ft3)

What is the volume of the right rectangular prism, in cubic centimeters? A prism has a length of 4 centimeters, height of 9 centimeters, and width of 3 centimeters. cubic centimeters

Answers

The formula for volume is V = lwh

This means that the volume is equal to the length times the width times the height.

Multiply the three numbers for your answer.

Length = 4, width = 3, height = 9

lwh = 4cm X 3cm X 9cm = 12cm^2 X 9cm = 108cm^3

And there you have it! Your final answer is 108 cm^3 OR 108 cubic centimeters!

What is a rectangular prism?

A rectangular prism is a three-dimensional solid shape with six faces that including rectangular bases. A cuboid is also a rectangular prism. The cross-section of a cuboid and a rectangular prism is the same. Volume of a rectangular prism = Area of a base × Height.

Given that, a prism has a length of 4 centimeters, height of 9 centimeters, and width of 3 centimeters.

We know that, the volume of a rectangular prism = Length×Breadth×Height

The length of a rectangle is 3 units more than the width. The area of the rectangle is
40 units. What is the length, in units, of the rectangle?

Answers

Answer:

8 units for the length

Step-by-step explanation:

Let l = length

w = width

l = w+3

A = l*w

substitute what we know

40 = (w+3) *w

distribute

40 = w^2 +3w

Subtract 40 from each side

0 = w^2 +3w -40

Factor

0 = (w+8) (w-5)

Using the zero product property

w+8 =0   w-5=0

w= -8   w=5

Since the width cannot be negative

w=5

l = w+3 = 5+3

l = 8 units

The asnwer is 8 units for the length
