Answer:
(1). [tex]h(t)=-4(t-1)^2+36[/tex]
(2). 1 minute
Step-by-step explanation:
They want you to factorize the equation in such a way that the vertex appears as a number in the equation; and you do that by using a method called completing the squareHere is our equation: [tex]h(t)=-4t^2+8t+32[/tex]We factor it by completing the square: But first remember this:A quadratic equation has the general form [tex]f(x)=ax^2+bx+c[/tex] Where a and b are the numbers before x squared and x respectively, and c is the number without an x, and f(x) is the value dependent on xIn this case x is tSo the steps are as followsEquate the equation to zero: [tex]-4t^2+8t+32=0[/tex] Divide each term by the (a) of the equation in this case is it -4, and we get: [tex]t^2-2t-8=0[/tex] Then take the new (c) to the other side of the equation, in the case we add 8 to both sides to get: [tex]t^2-2t=8[/tex] Now the tricky part, you have to add to both sides of the equation the square of half of the coefficient of t or number before t, not t squared just t and you get: [tex]t^2-2t+(-1)^2=8+(1)^2[/tex] Now the left side is in the square form, or it just means when you factor the left side, you get it as the square of a certain single term, in this case we get: [tex](t-1)^2=8+1[/tex] When we simplify we get: [tex](t-1)^2=9[/tex] Now any equation in this form, will give you the vertex when you equate the term in parenthesis to zero, and simplify: [tex]t-1=0,t=1[/tex] [tex]t=1[/tex] is the value of the t or time at the vertex To write the equation again, multiply every term with the (a) you used to get: [tex]h(t)=-4(t-1)^2+36[/tex] , and this is the equation for #(1)Now here is why we needed to get the vertex; the vertex tells us at what point the height either reaches its maximum/highest level, or where it reaches its minimum/lowest level So since the time (t) at the vertex is 1, in order to find the height at this time, just plug it into the equation:[tex]h(1)=-4((1)-1)^2+36\\h(1)=-4(0)+36\\h(1)=36[/tex] So that's the height at the vertexNow it can either be the maximum/highest height or the minimum/lowest height, in order to know this we check as followsRemember the (a) we used to factor the equation? -4, if the (a) value of a quadratic function is less than 0, then it is a maximum equation, mean whatever vertex you get will be the point where the equation reaches its biggest value.So at a height of 36 meters, and a time of 1 minute, the craft reaches its highest point.PLEAES HELP ME I SUCK AT MATH!!

Step-by-step explanation:
Rewrite the equation 3r - 6 = 39 by factoring the side that contains the variable r. Pls help
Answer:
r=15
Step-by-step explanation:
you would add 6 to the right side of the equation which would make it 3r = 45. Then you would divide 45 by 3, equaling 15. So that ends up with r = 15.
Whats the domain???
Answer:
HERE IT IS...
Step-by-step explanation:
the domain or set of departure of a function is the set into which all of the input of the function is constrained to fall. It is the set X in the notation f: X → Y, and is alternatively denoted as. Since a function is defined on its entire domain
Answer:
Very simple!
Step-by-step explanation:
The domain of a function is where the function is defined, for the values of x.
Long story short, see the function? Where the blue line passes over the x-vales is the domain. Where there is no blue line over the x-values does not belong to the domain.
Thus, the function is defined for [tex]-8\leq x\leq 8[/tex], or [tex][-8, 8][/tex].

A cubed aquarium tank holds 1,000 m^3 of water. How tall is the aquarium?
Answer:
10m
Step-by-step explanation:
formula to find volume of a cube is v=a ³
if the volume of the cube is 1000, then 1000=a³ (a being the length of an edge of the cube)(the edges of a cube are all the same length)
cube root of 1000 is 10
The required height of the cubed aquarium tank is 10 meters.
As given that, A cubed aquarium tank holds 1,000 m³ of water, the height of the aquarium is to be determined.
Volume is defined as the ratio of the mass of an object to its density.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
A cubed aquarium tank holds 1,000 m³ of water,
The volume of the cube = 1000
side ³ = 1000
side = ∛1000
side = 10
Thus, The required height of the cubed aquarium tank is 10 meters.

What is the slope of y<1/2x-5
Answer:
1/2 is the slope
Step-by-step explanation:
y=mx+b
Answer:
1/2
Step-by-step explanation:
y=mx+b
b= y-intercept
mx=slope
so whatever is mx is the slope for example
y=1/3x+2
1/3 would be the slope because it's mx
Shayla wants to refinish the floors in her kitchen. Shayla predicts she will be able to cover the room with 75 square feet of tile flooring. Will shayla be able to cover the floor with 75 square feet of tile flooring?
Answer:
No
Step-by-step explanation:
Remember, she didn't take note of possible defects that may arise during actual construction, hence her prediction may be inaccurate.
Also, the 75 square feet mentioned is more likely based on approximations, and so it is best to think of possible deviation in the actual length of the room due to measurement error.

can 72/1 be a unit of ratio
Answer:
yes
Step-by-step explanation:
say you have 72 girls for every boy then the ratio would be 72/1
Answer:
Yes it can!
Step-by-step explanation:
A unit ratio is a ratio that's been broken down all the way to 1. As long as it has a 1 (and just a single digit 1, not 11 or 21), it's a unit ratio.

The classrooms in Okahurst School District are painted every summer. Seven gallons of paint are needed to paint 3 classrooms. How many more gallons are needed to paint the 129 classrooms at North High School than the 48 classrooms at Edgewater Elementary? Assume the situation is proportional
Answer:
189 Gallons
Step-by-step explanation:
7 gallons for 3 classrooms, so 7/3 for 1 classroom
multiply 7/3 * 129 to get 301 gallons at North High School
multiply 7/3 * 48 to get 112 gallons at Edgewater Elementary
301 - 112 = 189 gallons more at North High School than at Edgewater Elementary

We need to create equations for both statements.
s=shirts j=jeans
(s & j can be replaced by any letter i just used s and j to avoid further confusion)

Answer:
1.275
Explanation:
The given equation is:
f(x) = 0.01(2)ˣ
We want to find the rate of change from 2 to 10 which means that we need to find the slope from 2 to 10.
We start by getting the y-values for each of the given x-values:
at x = 2 ..........> y = 0.01(2)² = 0.04 ...........> point is (2, 0.04)
at x = 10 .........> y = 0.01(2)¹⁰ = 10.24 .........> point is (10, 10.24)
Now, we get the slope as follows:
slope =
