I believe the answer is C! hope this helps! ^-^ brainliest helps too ;D
Answer:
-6
Step-by-step explanation:
(g o f)(9) is equivalent to g(f(9))
In this case, solve for f(9) where 9 replaces the x
-(9)+9
0
After that, you are now solving for g(0) because you are following PEMDAS
(0)^2+7(0)-6
-6
Answer:
20 seconds
Step-by-step explanation:
speed = distance/time
distance = speed * time
The faster racer will catch up to the slower racer in x meters ahead of the slower racer.
The faster racer is 40 meters behind the slower racer, so he travels x + 40 until he catches up.
Slower racer:
speed = 12 m/s
distance = x
time = t
Faster racer:
speed = 14 m/s
distance = x + 40
time = t (the same time as the slower racer)
Slower racer:
distance = speed * time
x = 12t
Faster racer:
x + 40 = 14t
System of equations:
x = 12t
x + 40 = 14t
Since the fist equation is already solved for x, substitute 12t for x in the second equation and solve for t.
12t + 40 = 14t
40 = 2t
20 = t
t = 20
The faster racer catches up in 20 seconds.
The terminal point is (0, 1) if the radius of circle is 1 and the value of an angle ø is 360 degree option (C) is correct.
<h3>What is a circle?</h3>
It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a unit circle with an angle ø = 360 degree.
The terminal point will be:
x = rcosø
y = rsinø
r = 1
ø = 360 degree
x = cos360 = 1
y = sin360 = 0
The terminal point (0, 1)
Thus, the terminal point is (0, 1) if the radius of circle is 1 and the value of an angle ø is 360 degree option (C) is correct.

Answer:
It would be 20
Step-by-step explanation:
As we can see, the sequence starts from 5 and increases by three each time. In fact, one possible formula for that sequence could be:
Let's confirm the formula by evaluating the first 6 terms:
