The function g(t) = -16t2 + vt + h represents the height of an object, g, in feet above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial height of h feet.

A model rocket is launched off the ground at an initial velocity of 80 feet per second.
Write a function that can be used to describe the flight of the model rocket.

A. g(t) = -16t^2 + 80

B. g(t) = -16t^2 + 80t

C. g(t) = -16t^2 + t + 80

D. g(t) = -16t^2 + 80t + 80

Answers

Answer 1

Answer:

B. g(t) = -16t² + 80t

Step-by-step explanation:

Given function:

g(t) = -16t² + vt + h

A model rocket is launched off the ground at an initial velocity of 80 feet per second.

This gives us

h = 0 and v = 80

The function becomes:

g(t) = -16t² + 80t

Correct option is B.

x = -0.583 (continuing) or -7/12

Answer:

x= -7/12

Step-by-step explanation:

Subtract the numbers

-3x+2-5x-7=4x+2

-3x-5-5x=4x+2

Combine like terms

-3x-5-5x=4x+2

-8x-5=4x+2

Add 5 to both sides of the equation

-8x-5=4x+2

Answer:

x = 14

Step-by-step explanation:

First, organize your work by showing that lines are similar

Line KV is similar to line RV

Line UV is similar to line LV

etc, etc.

=========================================

Now notice that line KV and line RV have the numbers 9 and 18 accordingly

and notice that it's an x2 difference.

==============================================

Now apply the same thing to line UV and LV and divide 26 by 2

That gets us 13

=======================================

Now plug 13 into the equation (2x - 15)

2x - 15 = 13

==========================================

Now solve for X

2x - 15 = 13

Add 15 to each side

2x − 15 + 15 =13 + 15

2x = 28

Divide both sides by 2

2x / 2 = 28 / 2

x = 14

2. Find the midpoint of PQ.

Answers

Answer:

c) (-2, -1)

Step-by-step explanation:

to find the midpoint of a line, u have to average its coordinates.

Coordinates of P = (2,6)

Coordinates of Q = (-6, -8)

The formula for finding the midpoint is this:

[tex](\frac{x_{1}+x_{2} }{2}, \frac{y_{1}+y_{2} }{2 } )[/tex]

this basically means u average the points. So for the midpoint's x coordinate, it'll be (2-6)/2 = (-4)/2 = -2

midpoint's y coordinate = (6-8)/2 = (-2)/2 = -1

Therefore, the coordinates of the midpoint are (-2, -1), option c

hope this helps!

Answer:

C

Step-by-step explanation:

Remark

Just eye balling the answer it looks to me like the midpoint is (-2,-1). Of course Eyeballing it is not the way to do math, but it tells you where it is approximately.

Given Points

P: (2,6)

Q: (-6,-8)

Solution

midpoint = (x1 + x2)/2, (y1 + y2)/2

midpoint = (2 + - 6)/2, (6 - 8)/2

midpoint = (-4/2, -2/2)

midpoint = (-2,-1)
