Answer: 3 3/7 hours
Step-by-step explanation:
you need to find out how much work they can do in an hour.
let x represent the total collaborative work
1/8 + 1/6 = 1/x
3/24 + 4/24 = 1/x
7x = 24
x = 24/7 or 3 3/7 hours (in decimal form this is 3.4286)
I cannot guarantee this is correct but hope it helped
Answer:
f^-1(x)= ![\sqrt[7]{x} /8](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Bx%7D%20%2F8)
Step-by-step explanation:
f(x)=8x^7
x^7=f(x)/8
x=![\sqrt[7]{x} /8](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Bx%7D%20%2F8)
f^-1(x)= ![\sqrt[7]{x} /8](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Bx%7D%20%2F8)
Answer:
A. The football does not reach a height of 15ft
Step-by-step explanation:
Given

Required
Determine which of the options is true
The option illustrates the height reached by the ball.
To solve this, we make use of maximum of a function
For a function f(x)
Such that:
:

i.e we first solve for 
Then substitute
for x in 
In our case:
First we need to solve
Then substitute
for t in 
By comparison:






Substitute
for t in 






This implies that the maximum height reached is 14.0625ft.
So, the option that answers the question is A because 
Add the 2 equations to eliminate the 2y. We get
2x = 6
x = 3
Plug x = 3 into the first equation:-
3 + 2y = 7
2y = 7 - 3 = 4
y = 2
Answer is x = 3 and y = 2
