During a pumpkin launching contest, two pumpkins are launched at the same time. The path of pumpkin A is modeled by the equation

amid [387]

You just need to solve for x in the equation:
–0.01x^2 + 0.32x + 4 = <span>–0.01x^2 + 0.18x + 5
0.18x=1
x= 5.55
h(5.55) = -0.01*30.86+0.18*5.55+5 = -0.3086+1+5=5.6914

The intersection point is (5.55, 5.69).
I hope that this is the answer that you were looking for and it has helped you.

The formula for height, in feet of a projectile under the influence of gravity is given by h=-16t^2+vt+s, where t is the time in

kifflom [539]

Answer:

1.55s

Step-by-step explanation:

The height equation of the projectile is given as;

h = -16t^2 + vt + s .......1

where;

t is the time in seconds,

v is the upward velocity at the start,

s is the starting height.

Given;

v = 70 ft/s

s = 5 ft

Substituting the values equation 1 becomes;

h = -16t^2 + 70t + 5

For the ball to reach 75 ft, h = 0

75 = -16t^2 + 70t + 5

-16t^2 + 70t + 5 - 75 = 0

-16t^2 + 70t - 70 = 0

solving the quadratic equation;

Time t = 2.83 s and t = 1.55s

Therefore, the ball will first reach 75 ft after 1.55 seconds.

M=7,r=8, t=2 ; mr/t = what

galina1969 [7]

Answer:

Step-by-step explanation:

Plug in the corresponding numbers to the corresponding variables. Note that:

m = 7

r = 8

t = 2

mr/t = (7 * 8)/2

(7 * (8/2)) = 7 * 4 = 28

28 is your answer.

How would I do this?

Veseljchak [2.6K]

we know that the shaded side is 90 degrees and we are given 28 degrees

So we add 90+28 and we get 118

Since a triangle has 180 degrees, we subtract 180-118 to fins the missing angle measure

180-118=62

x=62

Your equation is 180=90+28+x

Write an algebraic expression to represent the new x-coordinate after a reflection across the x-axis given any initial x-coordin

denpristay [2]

Answer:

$x' = x$

Step-by-step explanation:

Given

$Initial\ Coordinate = x$

Required

Find the new coordinate of x when reflected over x axis

Represent the new x value as x'

When a function is reflected over the x axis, the x value remains unchanged;

So, we have:

$x' = Initial\ Coordinate$

$x' = x$
