The function f(t) = -16t2 + 64t + 5 models the height of a ball that was hit into the
air, where t is measured in seconds and h is the height in feet.
This table represents the height, g(t), of a second ball that was thrown into the air.

Which statement BEST compares the length of time each ball is in the air?
The ball represented by f(t) is in the air for about 4 seconds, and the ball
represented by g(t) is in the air for about 3 seconds.
The ball represented by f(t) is in the air for about 5 seconds, and the ball
represented by g(t) is in the air for about 3 seconds.
The ball represented by f(t) is in the air for about 3 seconds, and the ball
represented by g(t) is in the air for about 5 seconds.
The ball represented by f(t) is in the air for about 3 seconds, and the ball
represented by g(t) is in the air for about 4 seconds.
The best statement that compares the length of time each ball is in the air is seen in the second option.
What is the function of a quadratic equation?A quadratic function follows the condition: f(x) = ax² + bx + c. Here (a, b, and c) are real numbers and a ≠ 0.
From the given information:
The function f(t) = -16t² +64t + 5 models the height of a ballWhere;
time (t) ⇒ secondsheight (h) ⇒ feetThe table given is as follows:
Time (in seconds) height, g(t) in feet
0 4
1 36
2 36
3 4
From the table, when t = 0, the function becomes:
f(t) = -16t² +64t + 5
f(t) = -16(0)² + 64(0) + 5
f(t) = 5
Therefore, we can conclude that the best statement that compares the ball is: f(t) is in the air for about 5 seconds, and the ball represented by g(t) is in the air for about 3 seconds.

Adults can burn 210
calories per hour riding a
bike. If your bike ride was
21 hours, how many
calories would 8 adults
burn?
Answer:
210 x 21 = 4410 calories burned for 1 adult
4410 x 8 = 35280 calories burned for 8 adults
Step-by-step explanation:
First you figure out how much calories are burned total for 1 adult on a 21 hour bike ride with the information that you know of how much adults burn.
Next you multiply your answer by 8 to figure out the total of calories burned for all 8.
Step-by-step explanation:
35280 calories would be burnt.
I think it will help you.
210×21=4410
Now,
4410×8= 35280.

Annabelle measured her bedroom as 11 ft times 13 ft, which is 143 square feet. she wants to change the units to square inches. which statements should she consider when converting? check all that apply. there are 12 inches in every foot. the length and width will change by a factor of 1.2 times 10 superscript 1. the length and width will change by a factor of 1.2 times 10 superscript 0. the area will change by a factor of (1.2 times 10 superscript 1 baseline) (1.2 times 10 superscript 1 baseline) = 1.44 times 10 superscript 2 baseline = 144, since area is length times width. the area will change by a factor of 2 (1.2 times 10 superscript 1 baseline) = (2 times 10 superscript 1 baseline) (1.2 times 10 superscript 1 baseline) = 2.4 times 10 superscript 2 baseline = 240, since both the length and width increase by that factor.
There are 12 inches in every foot and the area will be increased by 144 factors.
We know that the feet and inches are the units of length. One foot is 12 inches.
The length and the breadth are given as 11 feet and 13 feet.
The area of the bedroom is 143 square feet.
We know that 1ft = 12 in
So, The length would become 11 feet to 132 inches.
The breadth would become 13 feet to 156 inches.
What is the formula for the rectangle?The area of the rectangle = length × Width
Therefore, the area of the rectangle = 132 × 156
Since area of the rectangle= 20592 in .sq
The area of the bedroom increased by 144 factors.

Step-by-step explanation:
just apply the formula you can find immediately on the internet.
that is much faster than putting such a calculation question in here.
the area of a circle is
pi×r²
with r being the radius.
so, in our case we have
pi × 3² = pi × 9 = 28.27433388... ft²
when using 3.14 for pi we get 28.26 ft²
