The formula is in a quadratic formula shape: [tex]y = ax^2+bx+c[/tex]
The function is negative since the value 'a' the coefficient of x^2 is negative meaning that the quadratic function is facing downards. If you don't get this explanation, take a look at the diagram I uploaded.
That means the highest point of the graph is its vertex.
But we must find where the vertex is at or the 't' value.
't' value at which vertex is = [tex]-\frac{b}{2a} =-\frac{16}{2*(-16)} =\frac{1}{2}[/tex]
Now plug this 't' value into h(t) to find the maximum height, and we will get 36 feet.
Hope that helps!

What is the area of this trapezoid?
Enter your answer in the box.
Answers
Answer:
80
Step-by-step explanation:
i gotchuuuuu
okok so a really easy way that this can be done is by not doing the full trapezoid, but splitting it up into 2 triangles and 1 rectangle
area of triangle: 1/2BH
area of rectangle: LW
Ookie so first the triangles:
both have the exact same measurements:
7 is the base, and the height is 8. Even tho it doesn't say 8 on one of them, we can visually see that it is the same height.
So, for BOTH triangles, 8*7=56, divided by 2=28.
Now, the rectangle:
width is 3, and length is 8.
8*3=24.
ADD TOGETHER: 28+28+24=80
AREA=80
Answer:
80
Step-by-step explanation:
area of the two triangles
= (7x8)/2x2
= 56
area of the rectangle
= 8x3 = 24
area of the trapezoid
= 56+24
=80

A cardboard box is shaped like a cube. The length of each side is 15 inch
What is the volume of the box, in cubic inches?
Answers
Answer: 3375 cubic inches
Step-by-step explanation:
Formula for the volume of cube is : V=a^3
so V = 15*15*15
V= 3375 cubic inches
So: 15 times 15 times 15 equals 3375 cubic inches. 3375 is the volume.
The width and height are 15 because the cardboard box is shaped like a cube which makes the length height and width the same.

The mean is the average of the data. I remember this by thinking, 'the average person is mean.'To find the average, or mean, you would add all of the variables together and divide it by the number of variables. The number of variables here would be 10, because there are 10 litters.We would add the amount of kittens together and divide it by 10. This will get us 57 ÷ 10 = 5.7.To find the MAD, take the mean (5.7) and subtract each number from 5.7, then square it. For example... [tex][5.7 - 4]^{2}[/tex] would be solved by first subtracting what is in the parenthesis (PEMDAS) which gets us 1.7, then multiplying it by itself (1.7 • 1.7) which equals 2.89.Repeat this process for all data points.What I got for all of the data points [listed below]Once you get all of the data points, you add them all together. This gets you 32.5.Now you divide 32.5 by 10, (to find the average of it) which gets you 3.25.2.89.49.49.09.091.695.295.295.2910.89If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers.

point after the translation?
Answers
Translation involves changing the position of a point along the standard coordinate plane
The coordinate of the point after translation is (6,6)
How to translate the pointThe point is given as:
(-4,10)
When the point is translated 10 units right, the new coordinate becomes
(-4 + 10,10)
(6,10)
When the point is translated 4 units down, we have:
(6,10 - 4)
(6,6)
Hence, the coordinate of the point after translation is (6,6)

3x+3=x+21
Then, you can solve for x:
3x+3=x+21
2x=18
x=9
Plugging in 9 into either equation of BC or AD should give you 30 for both sides:
3(9)+3=30
(9)+21=30
For CD, you can also plug in 9 for x:
2(9)-9=18
Since AB and CD are labeled as congruent, both sides are 18.
x=9
AB=18
BC=30
CD=18
AD=30

What is the value of s?
Answers
Answer:
63
Step-by-step explanation:
(s-13) +s = s + 50
2s - 13 = s + 50
add 13 both sides, subtract the s from both sides
s = 63
Answer:
s = 63°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
s + 50 is an exterior angle of the triangle , then
s + 50 = s - 13 + s
s + 50 = 2s - 13 ( subtract s from both sides )
50 = s - 13 ( add 13 to both sides )
63 = s
