200 gallons-140 gallons= 60 gallons

60gal x 1 min/ 2 gal= 30 minutes

It would take her 30 more minutes.

Prove the following relations: 1) (1 - cos²A) (1 + tan²A) = tan²A​
JulsSmile [24]

Step-by-step explanation:

(1 - cos²A)(1 + tan²A) = tan²A

1 + tan²A - cos²A - cos²A · tan²A = tan²A

1 + tan²A(1 - cos²A) - cos²A = tan²A

1 - cos²A + tan²A(sin²A) = tan²A

sin²A + tan²A(sin²A) = tan²A

sin²A (1 + tan²A) = tan²A

sin²A (sec²A) = tan²A

sin²A (1/cos²A) = tan²A

(sin²A)/(cos²A) = tan²A

tan²A = tan²A → <u>Proved</u>

Given f(x) = e^x and g(x) = x – 2, what is the range of (g*f)(x)
frutty [35]

For this case we have the following functions:

f (x) = e ^ x\\g (x) = x-2

By definition we have to:

(f * g) (x) = f (x) * g (x)

Substituting:

(f * g) (x) = e ^ x (x-2)

The range of the function is given by all values of "and" valid. That is, all the real numbers.

ANswer:

(-∞,∞)
