Answer:
y=-3x+15
Step-by-step explanation:
To find the equation of the line, you need to find the slope and y intercept. The slope is pretty easy, as the line goes down by 3 after going up by 1. This means that the slope is -3/1=-3. The y intercept is also pretty easy, as you know that the line will increase by 3 every time you go back 1 to the left. 3*4=12, meaning that going back 4 will take you up 12. 3+12=15, meaning that the equation of the line is y=-3x+15. Hope this helps!
The equation should be equal expressed as C.) h = 10sin(π15t)+35 where 35 represents the initial height of the blade above the ground. The 15π represents the period. It is said that the blades <span>complete two rotations every minute. Hence the period should be 60/4 equal to 15. 10 represents the amplitude of length of the blades</span>
-7
complex numbers are in the form a+bi
-7 +0i
Cone volume - V=pi r^2 h/3
r= radius
h= height
cylinder volume - V=pi r^2 h
r= radius
h= height
the cylinder is 3 times the volume of the cone.
Answer:
Option C. -8
Step-by-step explanation:
They ask us to find
(fof)(0)
To solve this problem we must introduce the function f(x) within the function f(x)
That is, we must do g(f(x)).
So, we have:
f(x) = 3x-2
Then:
f(f(x)) = 3(3x-2)-2
This is:
f(f(x)) = 9x-6 -2
f(f(x)) = 9x-8
Now we must do x = 0
f(f(0)) = 9(0) -8
(fof)(0) = -8
The answer is: option c (fof)(0) = -8.
