Answer:
(f/g)(-5) = 5
Step-by-step explanation:
You mean, "determine the value of (f/g)(x) at x = -5."
That would be:
f(x) 2x - 20
------- = ------------ and we now substitute -5 for x:
g(x) x - 1
2(-5) - 20 -30
(f/g)(-5) = --------------- = -------- = 5
-5 -1 -6
Answer:
9n -10
Step-by-step explanation:
If n represents the number, the product of the number and 9 is 9n. That value decreased by 10 is ...
9n -10
_____
<em>Additional comment</em>
The English expression is ambiguous in that we cannot tell if the number is decreased by 10 before becoming part of the product (9(n-10)), or if the correct interpretation is the one shown above. The order of operations is used as a guide, telling us that the multiplication is done before the subtraction since there is no indication of grouping.
Answer:
D
Step-by-step explanation:
Answer D is correct. The indicated line segments are both radii of the circle and are thus of the same length (and thus, congruent).
Since ∝ < β you can throw out answers C and D. Using the relationship of sine and cosine being complementary angles you can plug in the two smallest values. Out of those two for 13° you get sin18°=cos72° and 13°+72°=90°, meaning these two angles are complementary.
