Answer:
B. 20
Step-by-step explanation:
Cos a = b/c
Cos 53° = b/25
b = 25 × 0,6 = 15
x = √(25² - 15²)
x = √(625 - 225)
x = √400
x = 20
Answer:
q=4/3
Step-by-step explanation:
simplify the right side, to 5/3
5/4q=5/3
multiply 4/5 on both sides
q = 5/3*4/5
q = 4/3
40xa^2 + 24 ax + 32 a =
all you have to do is factor out a 8a from each term
aka reverse distribution property
8a (5 a + 3x + 4)
Answer: y = 0.5cos(x), choice A
The parent function y = cos(x) follows this same basic pattern of the curve shown, but it starts off at (0,1) as its highest point. This graph has its highest point to be half as high, so we multiply by 1/2 or 0.5
