I think this is what you meant not sure tho

Step-by-step explanation:

|8| = correct as it is

|-8| = correct as it is

-|8| = |-8|

-|-8| = |8|

A ball is launched upward from the ground with an initial velocity of 20 ft/s. The height of the ball at time t is represented by the function h(t). h(t)=-16t^2+20t, where t is measured in seconds and h(t) is measured in feet. drag the values to the lines to complete each sentence. 1. The ball reaches its maximum height when t is seconds. 2. The maximum height of the ball is feet. 3. The balls hits the ground when t is seconds. OPTIONS: 0.4 0.625 0.8 1.25 5.44 6.25 12.5 25

1.-t₁ = 0,625 s

2.-h(max) = 6,25 f

3.-t = 1,25 s

Step-by-step explanation:

V₀ = 20 f/s

h(t) = - 16*t² + 20*t

h(max) = ??

h´(t) = - 32*t + 20

h(max) will occurs when V = 0 dh/dt = 0 then

- 32*t + 20 = 0

- 32*t = -20

t = 20/32

t₁ = 0,625 s

h(max) = h(0,625) = - 16*(0,625)² + 20*0,625

h(max) = - 6,25 + 12,5

h(max) = 6,25 f

c) The ball will hit the ground

t = 2*t₁

t = 2*0,625

t = 1,25 s

This is my final project for math and I need help Graphing Radical Functions, Radical Equations and Extraneous Roots, Solving Equations Containing Two Radicals You are on a team of architects. You are charged with building a scale-model replica of one section of a new roller coaster before construction gets underway. Certain reinforcement cables and struts are required to make the roller coaster sturdier. The goal for this project is for your team to determine where to place these cables or struts.

You have the first 2 here's most of the rest. Write the equation that models the height of the roller coaster. Start by writing the equation of the circle . (Recall that the general form of a circle with the center at the origin isx2+ y2 = r2. x^2+y^2=30^2, The radius is 30 ftx^2+y^2=900 Now solve this equation for y. Remember the roller coaster is above ground, so you are only interested in the positive root. y = √(900 -x^2) Graph the model of the roller coaster using the graphing calculator. Take a screenshot of your graph and paste the image below, or sketch a graph by hand. (Put this in you should be good ) y= root (900)-x^2 x^2+y^2=900 all your points should equal 30 and look like a semi circle, but on the top part of the top not the bottom. Write the equation you would need to solve to find the horizontal distance each beam is from the origin.(x=√30^2-25^2) Algebraically solve the equation you found in step 3. Round your answer to the nearest hundredth. 16.584.Explain where to place the two beams x= -16.58x=16.58 Graph the cable and the strut on the model of the roller coaster using the graphing calculator. Take a screenshot of your graph and paste the image below, or sketch a graph by hand 900= x^2 +y^2 y=root(900-x^2) y= ^2x +8 y= x-8 the intersection should be -10 and positive 10 enter those equation into your calculator. That's all I know so far

6. sabrina is making an open box from a piece of cardboard that has a width of 12 inches and a length of 18 inches. she’ll form the box by making cuts at the corners and folding up the sides so that the flaps are square. if she wants the box to have a volume of 224 in3, how long should she make the cuts? part i: given what you know about the box sabrina is making, write a polynomial to represent each dimension (width, length, and height) of the finished box. (3 points) width = length = height = part ii: the formula for volume is v = l • w • h.

Step-by-step answer

Part I
Let
x--------> represent the length of the cuts

For any given cut, the available distance is reduced by twice the length of the cut.
So
we can create the following equations for length, width, and height.
width: w = 12 - 2x
length: l = 18 - 2x
height: h = x

Part II
v = l * w * h
v = (18 - 2x)(12 - 2x)x
v = (216 - 36x - 24x + 4x^2)x
v = (216 - 60x + 4x^2)x
v = 216x - 60x^2 + 4x^3
v = 4x^3 - 60x^2 + 216x

Part III
The length of the cut has to be greater than 0 and less than half the length of the smallest dimension of the cardboard
So
0 < x < 6
If we use a value of x=1 in
we get a volume of:
v = 4x^3 - 60x^2 + 216x
v = 4*1^3 - 60*1^2 + 216*1
v = 4*1 - 60*1 + 216
v = 4 - 60 + 216v = 160 in³
Too small,
so
let's try x=2 in
v = 4x^3 - 60x^2 + 216x
v = 4*2^3 - 60*2^2 + 216*2
v = 4*8 - 60*4 + 216*2
v = 32 - 240 + 432v = 224 in³
And that's the desired volume.
So
let's choose a value of x=2 in
Reason?
It meets the inequality of
0 < x < 6
and it also gives the desired volume of 224 cubic inches.

Part IV
the table in the attached figure

Part V
Based on your table, what x-value creates a box with a volume of 224 in3?

based on the table
the answer Part V is
x=2 in

Part VI
width: w = 12 - 2x-----> w=12-2*2----> w=8 in
length: l = 18 - 2x-----> l=18-2*2-----> l=14 in
height: h = x----------> h=x------> h=2 in

A. There is no solution. For the inequality to be true, the value of x has to be negative. This is impossible because Wilmer can't have a negative number of Reading Response assignments.
