Answer: (f·g)(x) = -5x³ - 31x² + 62x + 18
(f·g)(-1) = -70
(fog)(x) = 25x² - 130x + 155
(fog)(-1) = 310
<u>Step-by-step explanation:</u>
f(x) = x² + 8x + 2 g(x) = -5x + 9
(f·g)(x) = (x² + 8x + 2)(-5x + 9)
= -5x³ + 9x²
- 40x² + 72x
<u> - 10x + 18</u>
= -5x³ - 31x² + 62x + 18
(f·g)(-1)= -5(-1)³ - 31(-1)² + 62(-1) + 18
= -5(-1) - 31(1) - 62 + 18
= 5 - 31 - 62 + 18
= -70
****************************************************************************************
(fog)(x) = (-5x + 9)² + 8(-5x + 9) + 2
= 25x² - 90x + 81
- 40x + 72
<u> + 2</u>
= 25x² - 130x + 155
(fog)(-1) = 25(-1)² - 130(-1) + 155
= 25 + 130 + 155
= 310
<em>It wasn't clear if you wanted multiplication or composition so I solved both.</em>
It is related to the three sides of right triangles, the formula for it is A2 +b2 =c2. and the 2s are the sqaures
Answer:
I don't have an image to show you, but I can explain where to put it
Step-by-step explanation:
A) Draw PQR Upside down, but in the top right corner.
B) Draw PQR in the bottom right corner.
It's a bit confusing, but it's the best I can do, ask questions if you need more explanation please :)
Answer:
Yeah, there is no way to solve the problem without either distance or time. The reason why is that you have the formula for distance already but without time you cannot get an answer. The equation for time is t=d/r. So in either situation you should have one or the other it is not possible without. Sorry:)
Step-by-step explanation:
<span>Table
Elapsed
Time (seconds) Distance Traveled (feet)
1 6.2
2 12.4
3 18.6
4 24.8
Explanation:
You can check that 6.2 / 1 = 12.4 / 2 = 18.6 / 3 = 24.8 / 4 = 6.2
So, the relationship between the distance traveled and the time elapsed is a constant:
distance traveled / time elapsed = 6.2
n / f = 6.2
=> n = 6.2 f
Answer: n = 6.2 f</span>
