O 11.49 foot-pounds
O 38.30 foot-pounds
O 574.53 foot-pounds
O 750.00 foot-pounds
Answers
Answer:
C) 574.53 foot-pounds
Step-by-step explanation:
got it right on edge :)
Awagon is being pulled by a force of 15 pounds. the required work done is 574.53 to pull the wagon So, Option C) is correct work done = 574.53.
What is work done?The work done is product of force and cosine of displacement.
Given; Awagon is being pulled by a force of 15 pounds. We need to find How much work is done in moving the wagon 50 feet if the handle makes an angle of 40° with the ground.
Force = 15 pounds
distance = 50 feet
Ф = 40°
We can calculate the work done as;
work done = force x displacement x cosФ
work done = 15 x 50 x cos40
work done = 15 x 50 x 0.76
work done = 574.53
Therefore, the required work done is 574.53 to pull the wagon.

Given:
[tex]\ln(y-8)=-2x+\ln C[/tex]
To find:
y as a function of x.
Solution:
We have,
[tex]\ln(y-8)=-2x+\ln C[/tex]
It can be written as
[tex]\ln(y-8)=\ln e^{-2x}+\ln C[/tex] [tex][\because \ln e^x=x][/tex]
[tex]\ln(y-8)=\ln (Ce^{-2x})[/tex] [tex][\because \ln (ab)=\ln a+\ln b][/tex]
On comparing both sides, we get
[tex]y-8=Ce^{-2x}[/tex]
Adding 8 on both sides, we get
[tex]y=Ce^{-2x}+8[/tex]
Therefore, the equation function is [tex]y=Ce^{-2x}+8[/tex].

What composition forms the equation p(x) when given the functions for h(x), f(x), k(x), and g(x)? PLEASE HELP!!!!! thank you!!!!! *will ofc give brainliest*
Answers
Answer: Choice B. k(h(g(f(x))))
For choice B, the functions are k, h, g, f going from left to right.
===========================================================
Explanation:
We have 4x involved, so we'll need f(x)
This 4x term is inside a cubic, so we'll need g(x) as well.
So far we have
g(x) = x^3
g( f(x) ) = ( f(x) )^3
g( f(x) ) = ( 4x )^3
Then note how we are dividing that result by 2. That's the same as applying the h(x) function
[tex]h(x) = \frac{x}{2}\\\\h(g(f(x))) = \frac{g(f(x))}{2}\\\\h(g(f(x))) = \frac{(4x)^3}{2}\\\\[/tex]
And finally, we subtract 1 from this, but that's the same as using k(x)
[tex]k(x) = x-1\\\\k(h(g(f(x)))) = h(g(f(x)))-1\\\\k(h(g(f(x)))) = \frac{(4x)^3}{2}-1\\\\[/tex]
This leads to the answer choice B.
To be honest, this notation is a mess considering how many function compositions are going on. It's very easy to get lost. I recommend carefully stepping through the problem and building it up in the way I've done above, or in a similar fashion. The idea is to start from the inside and work your way out. Keep in mind that PEMDAS plays a role.
38 boys and 22 girls visit a zoo
33 of these children have a voucher
Twice as many boys as girls do not have a voucher
Complete the frequency tree
Answers
The frequency tree will be 9 girls and 18 boys don't have a voucher.
How to calculate the value?Boys = 38
Girls = 22
Total = 60
Children who have a voucher = 33
Children who don't have a voucher = 60-33 = 27
Twice as many boys as girls do not have a voucher
Girls who don't have a voucher: x
Boys who don't have a voucher: 2x
Girls without voucher + boys without voucher: x + 2x = 27
3x = 27
x = 27/3
x = 9
Girls who don't have a voucher: x=9
Boys who don't have a voucher: 2x = 2(9) = 18
For frequency tree:
Total students: 60
Boys : 38
Boys who don't have a voucher : 18
Boys who have a voucher: 38 - 18 = 20
Girls: 22
Girls who don't have a voucher: 9
Girls who have a voucher: 22 - 9 = 13
