Answer:

After 1.87 seconds the skateboarder is 8 ft from the bottom of the hill.

Step-by-step explanation:

The quadratic function d = –2*x² + 15 models a skateboarder’s distance, in feet, from the bottom of a hill x seconds after the skateboarder starts moving down the hill.

You want to know after how many seconds the skater is 8 feet from the bottom of the hill. That is, with the distance being 8 feet, you want to calculate the time t. Replacing in the expression d by the value of 8 feet:

8=–2*x² + 15

Solving:

8-15 = -2*x²

-7= -2*x²

(-7)÷(-2)= x²

3.5= x²

√3.5=x

1.87= x

After 1.87 seconds the skateboarder is 8 ft from the bottom of the hill.

Answer:

Solution given:

Cos -θ:[tex]\frac{\sqrt{3}}{4}[/tex]

since cos -θ=Cos θ

Cos θ :[tex] \frac{\sqrt{3}}{4} [/tex]

[tex]\frac{\sqrt{b}}{h} [/tex]=:[tex] \frac{\sqrt{3}}{4} [/tex]

b=[tex]\sqrt{3} [/tex]

h=4

p=[tex] \sqrt{4²-(\sqrt{3})²} [/tex]=[tex] \sqrt{13}[/tex]

So

Sin θ=[tex]\frac{p}{h} [/tex]=[tex]\frac{\sqrt{13}}{4} [/tex]

So third one is a required answer.

Answer:

[tex]t = 0.375s[/tex]

Step-by-step explanation:

Given

[tex]h(t) = -16t^2 + 4t + 33[/tex] --- driver 1

[tex]Rate = 2ft/s[/tex] -- driver 2

[tex]height = 33ft[/tex]

Required

The time they passed each other

First, we determine the function of driver 2.

We have that:

[tex]Rate = 2ft/s[/tex] and [tex]height = 33ft[/tex]

So, the function is:

[tex]h_2(t) = Height - Rate * t[/tex]

[tex]h_2(t) = 33 - 2t[/tex]

The time they drive pass each other is calculated as:

[tex]h(t) = h_2(t)[/tex]

[tex]-16t^2 + 4t + 33= 33 - 2t[/tex]

Collect like terms

[tex]-16t^2 + 4t + 2t= 33 - 33[/tex]

[tex]-16t^2 + 6t= 0[/tex]

Divide through by 2t

[tex]-8t + 3= 0[/tex]

Solve for -8t

[tex]-8t = -3[/tex]

Solve for t

[tex]t = \frac{-3}{-8}[/tex]

[tex]t = 0.375s[/tex]

Answer: Area = 189

Step-by-step explanation:

How i got the answer was i just simply multiplied the numbers that they had provided for you up on the top. So you would do (21 x 9 = 189).  Then you would be left off with your answer 189, which is your surface area for the figure stated in the photo.

Answer:

149.04 in^2

Step-by-step explanation:

The image of the question can be seen below.

In the image, we can see two circles that intersect at a given point.

We know that the total area of the image is 350 in^2

We want to find the area of the shaded part.

Ok, this seems to be hard, so instead, let's find the area of the two non-shaded parts (two semicircles) and just subtract that area from the total area of 350in^2

The two non-shaded parts are half a circle of diameter 16 inches.

We know that for a circle of diameter D, the area is:

A = pi*(D/2)^2

Where pi = 3.14

And because we want to find the area of two semicircles of diameter 16 inches, is exactly the same as finding the area for a single circle of diameter 16 inches.

This is:

A = 3.14*(16in/2)^2 = 3.14*(8in)^2 = 200.96 in^2

Now we can just subtract this from the total area:

shaded area = total area - A

shaded area = 350 in^2 - 200.96 in^2

shaded area = 149.04 in^2

1. x = 105

2.x = 35

Answer:

x>3

Step-by-step explanation:

you would subtract 5x from 2x and get -3x+10 < 1

then subtract 10 from 1 and get -9 so

-3x<-9 then divide and flip sign x>3 hope this helps

Answer:

x>3

Step-by-step explanation:

1.subtract both sides

2x+10 -5 < 5x+1 -5

-3x+10<1

2.subtract 10 from both sides

-3x+10 -10 < 1 -10

-3x<-9

3.divide both sides with number including x

-3x < -9

-3      -3

= x > 3

Answer:

Joseph is correct

Step-by-step explanation:

To obtain the difference between the longest and shortest length of the rope ; all we need to do is find the range of the dot plot ; The value for the range is obtained thus ;

Range = Highest - Least value

Highest value or maximum = 12 feets

Minimum or least = 9 1/2 feets

The Range = difference between the longest and shortest length is : (12 - 9 1/2) feets = 2 1/2 feets

Answer:

C

Step-by-step explanation:

7 - 3 = 4 = Length

3 + c = ? = w

A = 32

32 ÷ 4 = 8 = w

8 - 3 = 5 = number added to width

5 = c

Word explanation:

To find the number added, you have to figure out the length so that you could divide it by area to figure out the width.

So, to do that, you follow what the question said, "Three centimeters are subtracted from the length." = 7 - 3 = l = 4

Then, you move on to figure out the width, so you divide the area by the length = 32 ÷ 4 = 8 = width.

Now that you know the width, you continue to follow what the question said, "C centimeters are added to width."

= 3 (previous width) + c = 8 (new width)

After that, you subtract 8 - 3 to find the amount added to the width and that gives you 5, which is C.

The value of the variable c is 5 centimeters.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

To determine the number added, we have to figure out the length so that we could divide it by area to figure out the width.

"Three centimeters are subtracted from the length means;

= 7 - 3 = l = 4

Then, move on to figure out the width, so we divide the area by the length

= 32 ÷ 4

= 8  width.

Now that we know the width, continue to follow what the question said, "C centimeters are added to width."

= 3 (previous width) + c = 8 (new width)

After that, subtract 8 - 3 to find the amount added to the width and that gives 5, which is C.

Answer:

$ 10,000

Step-by-step explanation:

Manuel wants to replace the wooden floor at his gym. The floor is in the shape of a rectangle. Its length is 50 feet and its width is 25 feet.

The gym floor is shaped like a rectangle

Area of a rectangle = Length × Width

= 50 feet × 25 feet

= 1250 ft²

Suppose wood flooring costs $8 for each square foot.

The wood flooring cost for the floor is calculated as

1 ft² = $8

1250ft² = x

Cross Multiply

1250 ft² × $8

$ 10,000

The wood flooring cost for the floor is $10,000
