Answer:
The area is 7850 square inches
Step-by-step explanation:
Given the circumference, we want to calculate the area
mathematically, the circumference is;
C = 2 pi r
So r is C/2 pi
Area = pi * r^2
Substitute value for r from circumference;
Area = Pi * c^2/4pi^2
Area = C^2/4pi
Area = 314^2/4 * 3.14
Area = 7850 Inches square
In the first day she drive by her self 300
The miles remains to the second day
582-300=282
In the second day it will share the driving with her cousin equally
so she will drive 282/2=141 miles and her cousin also 141 miles
The quadratic equation that models the height of the rocket after t seconds is:
s(t) = -4.9t² + 39.2t.
<h3>What is the quadratic function for a projectile's height?</h3>
Considering the height in meters, the equation is given by:
s(t) = -4.9t² + v(0)t + h(0)
In which:
- v(0) is the initial velocity, in m/s.
- h(0) is the initial height, in m.
In this problem, we have that v(0) = 39.2, h(0) = 0, hence the equation is:
s(t) = -4.9t² + 39.2t.

Answer:
His salary is $2666.68
Step-by-step explanation:
First add the percent of the costs. 10% + 15% = 25%
Then subtract 25% from 100% to find the percentage that 2,000 is of the total salary. 100% - 25% = 75%
$2,000 is 75% of the total salary. Divide 2,000 by three to find the amount of money 25% of the salary is. ( 75% is 3/4 of 100) 2,000 divided by 3 = $666.67
25% of the salary is $666.67
Multiple that by 4 and you get the total salary.
666.67•4= $2666.68
Are you sure those were all the correct numbers because that was not a very nice number at the end there lol but that answer is correct with the numbers you gave me.
