plz hurry!! A person standing close to the edge on top of a 108-foot building throws a ball vertically upward. The quadratic function h ( t ) = − 16 t 2 + 132 t + 108 h ( t ) = - 16 t 2 + 132 t + 108 models the ball's height above the ground, h ( t ) h ( t ) , in feet, t t seconds after it was thrown. a) What is the maximum height of the ball?
Answer:
The maximum height of the ball is 380.25 feet in the air.
Step-by-step explanation:
The quadratic function:
[tex]h(t)=-16t^2+132t+108[/tex]
Models the ball's height h(t), in feet, above the ground t seconds after it was thrown.
We want to determine the maximum height of the ball.
Note that this is a quadratic function. Therefore, the maximum or minimum value will always occur at its vertex point.
Since our leading coefficient is leading, we have a maximum point. So to find the maximum height, we will find the vertex. The vertex of a quadratic equation is given by:
[tex]\displaystyle \left(-\frac{b}{2a},f\left(\frac{b}{2a}\right)\right)[/tex]
In this case, a = -16, b = 132, and c = 108. Find the t-coordinate of the vertex:
[tex]\displaystyle t=-\frac{132}{2(-16)}=-\frac{132}{-32}=\frac{33}{8}=4.125[/tex]
So, the maximum height occurs after 4.125 seconds of the ball being thrown.
To find the maximum height, substitute this value back into the equation. Thus:
[tex]h(4.125)=-16(4.125)^2+132(4.125)+108=380.25\text{ feet}[/tex]
The maximum height of the ball is 380.25 feet in the air.
WHAT DOES THIS MEAN GIMME THE ANSWER
Answer:
This is a geometric sequence and the ratio is equal to 4.
Step-by-step explanation:
Arithmetic means you can continue the sequence through addition or subtraction.
Geometric means you can continue the sequence through multiplication or division.
To get from 3 to 12, we could either add 9 (arithmetic) or multiply by 4 (geometric).
To get from 12 to 48, we could either add 36 or multiply by 4.
Since we are looking for a pattern, the sequence would be geometric. This is because the sequence can be continued by multiplying by 4 each time. It cannot be arithmetic because we cannot add by 9 each time.
On a side note, common difference is used when describing arithmetic while ratio is used to describe geometric.

Adrian measured a line to be 13.8 inches long. If the actual length of the line is 13.1
inches, then what was the percent error of the measurement, to the nearest tenth of a
percent?
Answer:
5.34%.
Step-by-step explanation:
Given that,
Measured length of a line = 13.8 inches
Actual length of the line = 13.1 inches
We need to find the percent error of the measurement. We can find it as follows :
[tex]\%=\dfrac{|measured-actual|}{actual}\times 100\\\\\%=\dfrac{13.8-13.1}{13.1}\times 100\\\\\%=5.34\%[/tex]
So, the required percentage is equal to 5.34%.

Use the net to find the surface area of the prism
Answer
364 i think
Step-by-step explanation:
find the area of triangles + area of rectangles
area of triangles: b x h x 1/2
6 x 4 x 1/2
= 12
but two triangles, so . double it and then you get 24 for the two triangles areA
area of rectangles;
l x w
22 x 6
= 132
but two up and down rectangles, so double it = 264
now back rectangle:
l x w
22 x 4
= 88
Add it all up together and you have the surface area!
Surface Area - The area of the surface of the 3D object, NOT volume

Jacob has a list of the estimated costs for each semester to attend a four-year university. What is the total estimated cost to attend college for four years?
Tabel:
Item Cost
Tuition and Fees $3,725.00
Room and Board $2,800.00
Books and Supplies $700.00
Personal Expenses $900.00
A. $8,125
B. $16,250
C. $65,000
D. $32,500
Answer: A, 8125
Step-by-step explanation:
3,725 + 2800 + 700 + 900
3725 + 2800 = 6525
700 + 900 = 1600
6525 + 1600 = 8125
The total estimated cost to attend college for four years is $65,000.00.
Option C is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Number of semesters in 4 years.
= 2 x 4
= 8
Now,
To find the total cost to attend college for four years, we need to multiply the cost of each item by the number of semesters in four years and add them all together.
So,
Tuition fees:
8 semesters x $3,725.00/semester
= $29,800.00
Room and board:
8 semesters x $2,800.00/semester = $22,400.00
Books and supplies:
8 semesters x $700.00/semester = $5,600.00
Personal expenses:
8 semesters x $900.00/semester = $7,200.00
Therefore,
The total estimated cost to attend college for four years.
= $29,800.00 + $22,400.00 + $5,600.00 + $7,200.00
= $65,000.00
Thus,
The total estimated cost to attend college for four years is $65,000.00.

Can I get help with this problem please?
Answer:
B
Step-by-step explanation:
To find the y- intercept let x = 0
From the table for f(x)
When x = 0 → f(x) = - 4
That is the y- intercept = - 4
Given
g(x) = 3 [tex](2)^{x}[/tex]
let x = 0 , then
g(0) = 3 [tex](2)^{0}[/tex] [ [tex]2^{0}[/tex] = 1 ]
= 3 × 1
= 3
That is the y- intercept = 3
Thus the y- intercept of g(x) is greater → B

(B) Is the answer here
Step-by-step explanation:
Well a function’s domain can’t repeat no matter what.
Domain is X.
So the first one doesnt work since it repeats to every single digit that exists.
The second one works becuase the domain aren’t repeated and the range being repeated (or known as y) is but that deosn’t matter.
Answer:
B
Step-by-step explanation:
Hello There!
In order for the relations to be a function the x values may not repeat
For answer choice A the x value -2 repeats multiply times therefore the relation is not a function
For answer choice B each x value has a different y value so this might be our answer but just to be safe lets look at the other answer choices
For answer choice C the x values -3 and 2 repeat therefore it is not a function
For answer choice D the x value 2 repeats therefore the relation is not a function
So we can conclude that the correct answer is B
