A girl throws a paper airplane from her treehouse. The height of the plane is a function of time and can be modeled by the equation ℎ()=25+2.5−122. Height is measured in feet and time is measured in seconds.

Answers

h(0) show the initial height of the plane, that is 25 feet.

The given equation is h(t)=25+2.5t-1/2 t².

Here, h(0)=25+2.5(0)-1/2 (0)²

h(0)=25

This shows the initial height is 25 feet.

Therefore, h(0) show the initial height of the plane, that is 25 feet.

Find the surface area of a sphere with a circumference of 172 mm. Round to the nearest tenth.

9416.9 mm
27.4 mm
4708.4 mm
749.4 mm

Answers

Answer:

a. 9,416.9 mm²

Step-by-step explanation:

Given:

Circumference of a sphere = 172 mm

Required:

Surface area of the sphere rounded to nearest tenth

Solution:

First, we need to determine the radius of the sphere since we know the circumference.

Circumference = 2πr

Plug in the value of the circumference

172 = 2*π*r

Divide both sides by 2π

172/2π = r

86/π = r

r ≈ 86/π

Next, find the surface area of the sphere

Surface area = 4πr²

plug in the value of r

Surface area = 4*π*(86/π)²

= 4*π*86²/π²

= 4*7,396/π

= 9,416.87967

≈ 9,416.9 mm² (nearest tenth)

Lynette has a metal doorstop with the dimensions shown.
Each cubic centimeter of the metal in the doorstop has a mass
of about 8.3 grams. Find the volume of the metal in the
doorstop. Then find the mass of the doorstop.

Answers

Volume = 105in³

Mass = 871.5g

To find the volume of the metal we can find the area of a base, and multiply it by the prism's width.

The base is 30cm in area, and the width is 3.5cm, which makes the volume 105in³

The mass of the doorstop can be found by just multiplying the grams per cubic centimeter by the volume, which would be 871.5g

Dave's father is paying him to paint the storage
shed. Write a formula that will help them
decide how many cans of paint to buy.
Let's let
p = area covered by a can of paint
W = the total area of the walls
n = number of paint cans to buy.

Answers

Answer:

Number of paints to buy, n = The total area of the walls, W / Area covered by a can of paint, p

Step-by-step explanation:

Let's

p = area covered by a can of paint

W = the total area of the walls

n = number of paint cans to buy

Number of paints to buy, n = The total area of the walls, W / Area covered by a can of paint, p

That is,

n = W / p

If the total area of the walls = 100 m²

A can of paint covers 5 m². Find the number of cans of paint needed?

Number of paints to buy, n = The total area of the walls, W / Area covered by a can of paint, p

n = W / p

= 100 m² / 5 m²

n = 20 cans of paint

PLEASE HELP ILL MAKE BRAINLIEST

Answers

Answer:

56°

Step-by-step explanation:

180 = 40 + (2x) + (3x)

180 - 40 = 40 + 5x - 40

140/5 = 5x/5

x = 28

2(28)

= 56

Answer:

m∠A = 56°

Step-by-step explanation:

A triangle contains 180°. So

180 - 40 = 140

2x + 3x = 140

5x = 140

x = 28

Now, plug in the value for x.

2(28) = 56

Check your work.

40 + 56 + 84 = 180

According to the graph, what is the value of the constant in the equation
below?

Height=
Constant/Width

(4, 25)
(5, 20)
(10, 10)
(20,5)

Answers

Answer:

100

Step-by-step explanation:

x-value is width and y-value is height. Therefore if you multiply the height x width you get the constant.

The value of the constant in the equation is 100.

What is the graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.

Given that, Height=Constant/Width

1) (4, 25)

Here, Height = 25 and Width = 4

25 = Constant/4

Constant = 100

2) (5, 20)

Here, Height = 20 and Width = 5

20 = Constant/5

Constant = 100

3) (10, 10)

Here, Height = 10 and Width = 10

10 = Constant/10

Constant = 100

4) (20, 5)

Here, Height = 20 and Width = 5

20 = Constant/5

Constant = 100

Therefore, the value of the constant in the equation is 100.
