Answer:

2. [tex]\displaystyle 64\:feet[/tex]

1. [tex]\displaystyle 5\:seconds[/tex]

Step-by-step explanation:

2. Sinse we do not have a y-intercept [C-value in this case], we have to use a part of the quadratic formula to solve for x, and rewrite this equation in Vertex Form, with [tex]\displaystyle [h, k][/tex] as the vertex point. Observe:

[tex]\displaystyle -\frac{b}{2a} = x \\ \\ -\frac{64}{2[-16]} = \frac{-64}{-32} = 2[/tex]

Now, keep in mind that [tex]\displaystyle -h[/tex] in the vertex formula, [tex]\displaystyle y = a[x - h]^2 + k,[/tex] gives you the OPPOSITE TERMS OF WHAT THEY REALLY ARE, so in this case, sinse 2 is already positive, you do not need to alter its operation sign. With this being stated, you should already have this:

[tex]\displaystyle y = -16[x - 2]^2[/tex]

Now, to find k, all you have to do is plug 2 into the TOP equation to get your maximum height:

[tex]\displaystyle -16[2]^2 + 64[2] = -16[4] + 128 = -64 + 128 = 64 \\ \\ \\ y = -16[x - 2]^2 + 64[/tex]

Therefore, sinse 64 is your k-value, 64 feet is indeed your maximum height.

1. Simply factour the quadratic equation:

[tex]\displaystyle y = -18x^2 + 90x \\ 0 = -18x[x - 5] \\ \\ 5, 0 = x[/tex]

In this case, from a height of sixty-four feet, it is IMPOSSIBLE for the football to hit the ground in zero seconds, therefore the ball will reach the ground in 5 seconds, which makes alot more sence.

I am joyous to assist you at any time.

** Minimum Height → [tex]\displaystyle A[/tex]

** Maximum Height → [tex]\displaystyle -A[/tex]

Step-by-step explanation:

Answer:

They're the same shape and size, just angled differently.

Answer:

volume of entire shape = 80 + 32 = 112 cubic inches

Step-by-step explanation:

area of rectangle = 80 in³

area of square pyramid = 1/3 · b² · h       (b = base)

A = 1/3 · 4² · 6  =  16 · 2  = 32 in³

Answer:

A

Step-by-step explanation:

A constant line looks like a flat line with a slope of 0.

The segment that shows a constant function is segment A.

Option A is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

A function is constant if the graph is a straight line.

So,

From the given graph, we see that line A is a straight line.

This means,

Segment A shows a constant function.

Thus,

The segment that shows a constant function is segment A.

Answer:

(B)  24

Step-by-step explanation:

Answer:

The median is 16.

Step-by-step explanation:

To find the median of a set, first we sort the set in an incresing way. So

3,5,8,11,15,16,18,22,23,32,36

The set has 11 elements, so the median will be element at the position (11+1)/2 = 6, that is, the 6th element of the sorted set.

In this case, the median is 16.

Answer:

If Kareem were to work for 5 hours, she would get paid $45.

Step-by-step explanation:

If she gets paid $72 for working 8 hours, you would need to find how much she gets paid per hour by doing [tex]72/8[/tex].

Which then gives you $9 per hour, so then all you need to do is multiply $9 by the number of hours which in this case is 5 to get the answer of $45.

Step-by-step explanation:

So lets multiply the parantheses by -3 we get

-3×2x-3×6

Which we can write as

-6x-18

Answer:

[tex]\huge\boxed{\boxed{{\boxed{{-6x-18}}}}}[/tex]

Step-by-step explanation:

Hello.

In order to simplify the expression, we should multiply -3 times 2x and 6:

-3 times 2x = -6x

-3 times 6=-18

-6x-18

And we're done!

Answer:

Step-by-step explanation:

So, first lets the probability of just finding a yellow marble. There are 9+5+2+4 marbles in total, and that is 19 marbles.

5 out of those 20 are yellow, so the probabilty is 5/20 which is 1/4 or 20%

Then, lets do just finding the probability of a color that isn't blue.

Out of 20 marbles, 11 are color not blue, and 9 are.

So that probability is 11/20

Now, I think we need to do 11/20-5/20 so 6/20=3/10

Im so sorry, I might be wrong. I found both probabilities but I dont know if my final step is right.

Answer:

7% does not represent the part 0.7 of the push-ups Malik completes because 7% is NOT equivalent to 0.7.

Step-by-step explanation:

Given that Malik completes 0.7 of the total number of push-ups his coach requires.

Checking the given options:

7% = 7/100 = 0.07

14/20 = 0.7

70% = 70/100 = 7/10 = 0.7

0.70 = 0.7

Therefore,

7% does not represent the part 0.7 of the push-ups Malik completes because 7% is NOT equivalent to 0.7.

Answer:

None are correct.

Step-by-step explanation:

10/30 wanted pepperoni, so 1/3 of them wanted pepperoni.

15/30 wanted cheese, so 1/2 wanted cheese.

5/30 wanted hamburgers, so 1/6 wanted hamburgers.

You can use this information to estimate the number of the 150 students who wanted each.

1/3 of 150 = an estimated 50 wants pepperoni

1/2 of 150 = an estimated 75 wants cheese

1/6 of 150 = an estimated 25 wants hamburgers

Now you can use this to see which one is true.

A. There are 40 students who want pepperoni

not true, there are 50

B. There are 100 students who want either pepperoni or hamburger

50(pepperoni) + 25(hamburger) = 75, so this is not true

C. There are 10 more students who will want cheese than hamburger

75(cheese) - 25 (hamburger) = 50, so this is not true.

D. There are 5 more students would want pepperoni than hamburger

50 (pepperoni) - 25 (hamburger) = 25, so this is not true

None of these answers are correct
