A skateboarder leaves a 12-foot tall ramp with an initial vertical velocity of 8 feet per sen
function f(h) = -8t² +8t + 12 represents the height, h, in feet of the skateboarder after t seconds.
How many seconds was the skateboarder airbound

Answers

Answer 1

To answer this, we substitute 12 ft to the f(h) in the given equation,   
f(h) = -8t² + 8t + 12 = 12

Subtracting 12 from both sides of the equation will give us an answer of,

-8t² + 8t = 0

Then, we transpose 8 to the other side and divide the equation by -8 and t, we get an answer of t = 1 second. 

Answer 2

Answer:

Below in bold.

Step-by-step explanation:

When he lands h = 0  so

-8t^2 + 8t + 12 = 0

Solving for t

t = [-8 +/- sqrt(8^2 - 3*-6*12)] / -16

t = 1.82 seconds.

6. A right triangle includes one angle that
measures 30°, What is the measure of
the third angle?
A 30°
C 60°
B 90°
D 130°

Answers

Answer:

C, 60 degrees

Step-by-step explanation:

Right Triangle, with a 30 degree angle:
Given degrees:
90 (Right Triangle)
30

90+30 = 120
180-120 = 60

180 Degrees total in a triangle, you simply subtract the measure you have to fidn the third one.

Answer:

The measure of the third angle is 60°.

Step-by-step explanation:

We are given a right triangle that has a 90 degree and two other angles that are unknown.

Since one known angle is 90° and another angle given is 30° then the third angle must be 60°. All triangles must add up to 180°.

180° - 90° -  30° = 60°.

Answer:

y = x/2

Step-by-step explanation:

y = -x has a negative slope so cross this one out.

y = 2x has a steeper slope that would be above the black line so cross this one out

y = 0.001x has a slope that acends very slowly so cross this one out.

y = x/2 is the best match.

Some terminology:

 ⇒what is the slope

    ⇒ is the steepness of the line

        ⇒calculated by dividing the rise over the run

           ⇒ rise is the change in the y-direction

               ⇒ run is the change in the x-direction

                  ⇒look at the diagram I attached

 ⇒ how to find the slope in a linear equation

     ⇒look to the coefficient of the 'x' variable

        ⇒ that is the slope

      Ex. For the line y = x, the slope is 1

A line with a positive slope rises from left to right while a line with a    negative slope falls from left to right.

   Ex. y=x has a positive slope and thus is rising

   

We want to find the equation that could represent the blue line

   ⇒ let's look into each equation and see whether they work or not

First case: [tex]y = -x[/tex]

  ⇒The equation given has the line falling, when the graph in the    

  equation is rising

       ⇒ not the answer

Second case: [tex]y=2x[/tex]

   ⇒ the equation given has the line that has a bigger slope than the

  the equation shown, which has a smaller slope than y = x

       ⇒ not the answer

Third case: [tex]y=\frac{1}{2}x[/tex]

    ⇒ the equation given fits the requirement of having a rising slope that

    is smaller than y = x

        ⇒ is a possible answer

Fourth case: [tex]y = 0.001x[/tex]

     ⇒ the equation given has a slope that is almost horizontal when the

     line shown in the graph doesn't

          ⇒ not the answer

Thus after examing all the choices:

   ⇒ Answer: [tex]y=\frac{1}{2}x[/tex]

Answers

The minimum amount to the nearest dollar according to the line of best fit from the graph is $26 because as y = $26, x = 0.

What is the line of best fit?

The line of best fit is a line that runs across a scatter plot of data points and best reflects the connection between them.

Let's make an assumption from the image below that;

x = the total amount($) of her customers’ bills and;y = her total daily wages.

We know that x = 0 at the y-intercept;

Thus, the minimum amount to the nearest dollar according to the line of best fit from the graph is $26 because as y = $26, x = 0.

Please Help !! What is the volume of a cylinder with base radius 2 and height 9?

Answers

Answer:

The cylinders volume is 113.04 cubic inches

Step-by-step explanation:

The volume of a cylinder can be represented by the formula : V = π*r^2*h

So, now that we have the formula, we can simply plug in the values, and we have the volume of the cylinder.

V = π * 2^2 * 9

V = π * 4 * 9

It says to use 3.14 as π.

V = 3.14 * 4 * 9

V = 113.04

The cylinders volume is 113.04 cubic inches

how do you round 81.59 to the nearest whole number?

Answers

Answer:

The number (81.59) will round to 82.

Step-by-step explanation:

First, let us understand what the question means by "whole numbers".

What are whole numbers?

Whole numbers are such integers that are positive. (Except 0, which is a non-positive and non-negative integer).

Whole numbers: 0, 1, 2, 3, 4, 5, 6....

If the number before the decimal is smaller than 50, then the number will round down. If the number before the decimal is greater than or equal to 50, then the number will round up.

We can see that 81.59 is between two integers (81 and 82). Therefore, 81.59 can either round down to 81 or round up to 82.

Since the number after the decimal (81.59) is greater than 50, the number rounds up to 82. Therefore, the number (81.59) will round to 82.

. What is the circumference of a 12-inch diameter pizza? Leave the answer in terms of π.

Answers

The formula for the circumference of a circle is 2πr, where r is the radius, or πd, where d is the diameter.
I’m assuming they want the diameter in cm which is simple enough. 1 inch ≈ 2.56cm so 12 inches ≈ 30.72cm.
So using the formula from before, πd, we get the answer 30.72π.
If they want the diameter in inches then it is simply 12π but this is unlikely.

The radius is given ad 6. So the circumference is:

Now, since the angle of the arc is 90°, this is 1/4 of the circle.

This means that the arc length of this section will be 1/4th of the total circumference which is:

If a canoe travels 6 miles per hour downstream, and 2 miles per hour p stream, how many miles per hour will it go in still water?

Answers

Answer:

  4 miles per hour

Step-by-step explanation:

The given relations allow us to write two equations.

__

The downstream speed is the sum of the canoe speed and the stream speed:

  6 = c + s

The upstream speed is the difference of the canoe speed and the stream speed:

  2 = c - s

Adding these two equations, we get ...

  8 = 2c

  4 = c . . . . . divide by 2
