Answer:
fh. = 40h + 120, fh. = $200
200 = 40h + 120
200 - 120 = 40h
80 = 40h
80/40 = h
2 = h
h = 2 hours.

Answer:
(-3/4, -7/2)
Step-by-step explanation:
y= −2x − 5
y= 2x − 2
2y = -7
y = -7/2
y= 2x − 2
-7/2 = 2x - 2
2x = -3/2
x = -3/4
(x,y) = (-3/4, -7/2)
Remark
<u>Two facts.</u>
1) Tan(x) = Sin(x) / Cos(x)
2) Csc(x) and Sin(x) are reciprocal relationships. When multiplied together, they equal 1.
Solution
So Csc(x) * tan(x) = csc(x) * sin(x) / cos(x) = 1/cos(x) = sec(x)
So far what we have is tan^2(x) + sec(x). We have to get rid of tan^2(x)
Use the identity of 1 + tan^2(x) = sec^2(x)
tan^2(x) = sec^2(x) - 1
sec^2(x) - 1 + sec(x)
a^2 + a - 1 <<<<<< Answer
B is the answer.
Answer:
(A) 0.08
Step-by-step explanation:
P(A) = 0.8
P(B) = 0.1
P(A and B)
= 0.8 x 0.1
= 0.08
