Given F(x)=x-5 and G(x)=x^2 you want to find F(F(x)).
In order to do this, you don't need to know what G(x) is. Just put F into F...
F(x)=x-5
F(x-5)=x-5-5
F(F(x))=x-10
This is the question that you asked, but the photo makes it look like they want you to do G(F(x)) so I will do that one too.
G(x)=x^2
G(x-5)=(x-5)^2
THEREFORE...
G(F(x))=(x-5)^2
A is the answer!
EXPLANATION:
Remember that a function is like a machine. F(x) is a machine and G(x) is also a machine. Plugging F into G is basically taking the output of the F machine and putting it into the G machine.

Genghis Motors wants to build cars and motorbikes on a budget. The company plans to spend at most $75000 and use at least 320 workers to build cars and motorbikes.
8000C+5500M≤75000 represents the number of cars C and motorbikes M the company can build by spending at most $75000.
52C+38M≥320 represents the number of cars and motorbikes the company can build by using at least 320 workers.
Can the company meet both of its expectations by building 4 cars and 6 motorbikes?

Tan θ = 30/100
θ = 16.70, but since it is in an anticlockwise direction it will be -16.7
using Pythagoras theorem
a²+b²=c²

c = √(100²+30²)

combine like terms
2x^2 + 6x + 9= 45
subtract 9 from both sides

ANSWER: x= 3
Hope this helped! :)
The positive integer is [tex]3[/tex]
Let the number be [tex]a[/tex]
square of [tex]a = a^{2}[/tex]
Square of [tex]3[/tex] more than [tex]a[/tex] = [tex](3+a)^{2}[/tex]
[tex](3 + a)^{2} = (3+a)(3+a) = 9 + 3a + 3a + a^{2} = a^{2} + 6a + 9[/tex]
[tex]a^{2} + a^{2} + 9a + 9 = 45[/tex]
[tex]2a^{2} + 6a + 9 = 45[/tex]
Subtract 9 from both sides :
[tex]2a^{2} + 6a = 45 - 9[/tex]
[tex]2a^{2} + 6a = 36[/tex]
Divide through by 2
[tex]a^{2} + 3a = 18\\a^{2} + 3a - 18 = 0[/tex]
Factorize :
[tex]a^{2} + 6a - 3a - 18 = 0\\a(a + 6) - 3(a + 6) = 0\\a + 6 = 0\\or\\a - 3 = 0[/tex]
[tex]a = 3 ;\\or\\a = - 6[/tex]
since, a is a positive integer, then [tex]a = 3[/tex]

Answers
Using elimination:
3c+l=2700
5c+2l=4900
We will make the coefficients of l the same by multiplying the top equation by 2:
2(3c+l=2700)
6c+2l=5400
Our system is now
6c+2l=5400
5c+2l=4900
Subtract the bottom equation:
6c+2l=5400
-(5c+2l=4900)
We have
1c=500
So each camera is 500.
Substitute that in our original first equation:
3(500)+l=2700
1500+l=2700
1500+l-1500=2700-1500
l=1200

A rectangle has a a perimeter of 72 ft. The length and width are scaled by a factor 3.5.
What is the perimeter of the resulting rectangle?
Enter your answer in the box.
Answers
P=2(L+w)
P=2L+2w
Here Perimeter, p= 72 ft
And scale factor of length and width=3.5 which means rectangle is enlarged.
So perimeter of rectangle= 3.5 x 72
P=252ft
Answer: 252 ft
We also know that the perimeter P of the rectangle is defined as:
P=2L+2W.
So P is directly proportional to L+W. This means that if L or W were to get bigger, P will get bigger, and if L or W were to get smaller P will get smaller.
The question also states that both L and W are scaled by the same factor of 3.5 .
This means the sum of the dimensions L+W is scaled by 3.5
It also means that the perimeter is upscaled by 3.5 as it is proportional to L+W.
P = 72 ft × 3.5 = 252 ft.
252 ft is the answer.

Jackson currently has $35 in his bank account , he is saving $15 a week to eventually buy a new cell phone. He can represent the amount in his account with the equation y=15x+35.
I also need help answer the other questions to
Answers
Answer:
1. We have our function y = 15x + 35
a) Where the x represents the numbers of weeks since each week he is saving $15, which is the independent variable.
b) Where the y represents the total money he has, which is the dependent variable.
c) the slope is 15, as x increments, the slope goes up by 15.
d) The y-intercept is 35, because when x = 0, y = 35.
2. To create the table you have to find the value of y, knowing the values of x.
Using our function, when x = 0
y = 15(0) + 35
y = 0 + 35
y = 35
Using our function, when x = 1
y = 15(1) + 35
y = 15 + 35
y = 50
Using our function, when x = 2
y = 15(2) + 35
y = 30 + 35
y = 65
Using our function, when x = 3
y = 15(3) + 35
y = 45 + 35
y = 80
Using our function, when x = 4
y = 15(4) + 35
y = 60 + 35
y = 95
Using our function, when x = 5
y = 15(5) + 35
y = 75 + 35
y = 110
Yes, the table is proportional, because for each week, the value of his money is increasing by 15.
3. To create the graph, you can put the values of the table into the graph
And the graph is not proportional because to be proportional the relationship between “x” and “y” should be constant, meaning that, if “x” changes, “y” changes by the same percentage.
In this case our function has an intercept of 35 meaning that at week 0, he has $35 saved,
after a week: $50,
after two weeks: $65,
So, although is linear, is not proportional because when you double the weeks saved, you don't double the money saved.
Write -3r+3u in polar form PLEASE HELP

-3r+3u
Step 1
Use the distance formula to find the radius
r = √(x^2 + y^2)
(x,y)----------> (-3,3)
r= √(-3^2 + 3^2)=√18=3√2
Step 2
Use the tangent to find the angle
θ = arctan(y/x)
θ = arcTan(3/-3)= -45°-------> II Quadrant
then
θ=180-45=135°
Step 3
write in polar form

so
(-3,3)----------> (3√2, 135°)
the answer is (3√2, 135°)

Which is a possible number of distinct real roots for a cubic function? Select all that apply.

Answers
I don't know how to explain, but 3
Answer: The answer is 1 and 3.
Step-by-step explanation: We are to select the correct options about the number of real roots of a cubic function.
We know that there are three roots of a cubic function, out of which one must be real because the least number of real roots of an odd degree function is 1.
Also, if the second root is real, then the third one must also be real because the complex roots of a function occur in pairs.
Therefore, there is one real root or three real roots for a cubic function.
Thus, the answer is 1 and 3.

Two travellers spend from 12 o'clock to 6 o'clock walking along a level road, up a hill and back again. Their pace is 4 mph on the level, 3 mph uphill, and 6 mph downhill.
How far do they walk and at what time do they reach the top of the hill?
Answers
d = distance
r = rate of speed
time to walk uphill : t1 = d/3
time to walk downhill: t2 = d/6
total distance = 2d ( up hill and down ill)
2d = (d/3 + d/6)r
2/(1/3 +1/6) = r
r = 4
average speed up and down the hill was 4 mph
total distance = (2/3 x 6 x 4) + (1/3 x 6 x 4)
total distance = 16 + 8 = 24 miles total
Average speed to top of hill = 2/(1/4 +1/3) = 3.43 mph
to top of hill = 24/2 = 12 miles
12 / 3.43 = 3.5 hours
12 oclock + 3.5 hours = 3:30
total miles was 24
arrived at top of hill at 3:30
time to walk downhill: t2 = d/6
total distance = 2d ( up hill and down ill)
2d = (d/3 + d/6)r
2/(1/3 +1/6) = r
r = 4
average speed up and down the hill was 4 mph
total distance = (2/3 x 6 x 4) + (1/3 x 6 x 4)
total distance = 16 + 8 = 24 miles total
Average speed to top of hill = 2/(1/4 +1/3) = 3.43 mph
to top of hill = 24/2 = 12 miles
12 / 3.43 = 3.5 hours
12 oclock + 3.5 hours = 3:30
