Answer:
1. 20
2. 23
3. 6
Step-by-step explanation:
We have that:
f(x) = 2x
g(x) = x² + 1
f(g(x)) is the composite function of f and g. So
f(g(x)) = f(x²-1) = 2(x²+1) = 2x² + 2
1. f(g(3))
f(g(x)) = 2x² - 2 = 2(3)² + 2 = 18 + 2 = 20
2. f(3)+g(4)
f(3) = 2(3) = 6
g(4) = 4² + 1 = 17
f(3) + g(4) = 6 + 17 = 23
3. f(5) - 2g(1)
f(5) = 2(5) = 10
g(1) = (1)² + 1 = 2
f(5) - 2g(1) = 10 - 2*2 = 10 - 4 = 6
The answer is 17/25. Hope this helps! :) I know how you feel!
Let the lowest score be x.
<u>The 3 consecutive even scores are:</u>
1st score = x
2nd score = x + 2
3rd score = x + 4
-
<u>Sum of their score is 270:</u>
x + (x + 2) + (x + 4) = 270
-
<u>Solve x:</u>
x + (x + 2) + (x + 4) = 270
x + x + 2 + x + 4 = 270
3x + 6 = 270
3x = 264
x = 88
-
<u>Find their scores:</u>
1st score = x = 88
2nd score = x + 2 = 88 + 2 = 90
3rd score = x + 4 = 88 + 4 = 92
-
Answer: The scores are 88, 90 and 92
Answer:
251.2 unit²
Step-by-step explanation:
Radius = 4 unit, height = 5 unit
Volume of cylinder = pi r² h
Where pi(#) = 3.14
Volume = # × 4² × 5
Volume = # × 16 × 5
Volume = 80# unit²
Volume = 80 × 3.14
Volume = 251.2 unit²
