Answer:
$12 a week
Step-by-step explanation:
If he gets paid $168 for 14 weeks, to find 1 week's worth, divide 168 by 14 to get 12.
Answer:
Option A
Step-by-step explanation:
Domain should be greater than/equal to 1 for the function to be one-one.
f has vertex at (1,0)
f inverse has (0,1)
f(x) = 4
(x - 1)⁴ = 4
x = 2.414
On f: (2.414, 4)
On f inverse: (4, 2.414)
Answer:
V≈1282.82
Step-by-step explanation:
V=πr^2h
3=π·72·25
3≈1282.817
Answer:
C
Step-by-step explanation:
First do what’s in the parentheses. Do copy flip flip
1/4 x 4/7 = 1/7
Then do multiplication 7/5 x 1/7 = 1/5
Then multiply 1/5 by -10 and you get -2
x = 9.21° or x = 22.5°
cot²2x – 4cot2x + 3 = 0
Let cot2x = y
y² - 4y + 3 = 0
Factorizing, we have
y² - y - 3y + 3 = 0
y(y - 1) -3(y - 1) = 0
(y - 1)(y - 3) = 0
y - 1 = 0 or y - 3 = 0
y = 1 or y = 3
Since cot2x = y
cot2x = 1 or cot2x = 3
1/tan2x = 1 or 1/tan2x = 3
tan2x = 1 or tan2x = 1/3
2x = tan⁻¹(1) or 2x = tan⁻¹(1/3)
2x = 45° or 2x = 18.43°
x = 45°/2 or x = 18.43°/2
x = 22.5° or x = 9.21°
So, x = 9.21° or x = 22.5°
