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.

I need help pls 3(2x + 5) ≥ 2(x + 6)

Answers

Answer:

-3(2x-5)<5(2-x)

Step-by-step explanation:

hope this helps

Answer:

x ≥ -3/4

Step-by-step explanation:

3(2x + 5) ≥ 2(x + 6)

Distribute

6x+15 ≥ 2x + 12

Subtract 2x from each side

6x-2x+15 ≥ 2x-2x + 12

4x+15 ≥ 12

Subtract 15 from each side

4x+15-15 ≥ 12-15

4x ≥ -3

Divide each side by 4

4x/4 ≥ -3/4

x ≥ -3/4

What is the slope of y<1/2x-5

Answers

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?

Answers

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.

Whats the domain???​

Answers

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].

Sorry about the bad explanation.

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 =

What is the solution of the system? Use substitution.
−4y − 3x = −11
x − 2y = 17

Answers

Answer:

Explanation:

-4y - 3x = -11 (1)

x - 2y = 17 (2)
x = 17 + 2y

Substitute x value in (1)

-4y - 3(17 + 2y) = -11
-4y - 51 - 6y = -11
-10y - 51 = -11
-10y = -11 + 51
-10y = 40
y = 40/-10
y = -4

Substitute the y value in (2)

x - 2(-4) = 17
x + 8 = 17
x = 17 - 8
x = 9

Therefore, x = 9 and y = -4

Answers

Answer:

x < 5

Step-by-step explanation:

You can solve an inequality much like you would solve a normal equation.

There are 2x on the left side of the inequality, so divide both sides by two to find what x equals:

2x < 10

(2x)/2 < (10)/2

1x < 5

x < 5
