Answer:
B-total cost, c, of buying g pounds of broccoli,
C speed of a car, s, as it accelerates over time,
E-total distance, d, that has been driven over time, t
F-decrease in outside temperature, F, one evening over time, t
Step-by-step explanation:
d. 16,092
Staples: 1452 x 9 = 13,068
Office Depot: 504 x 6 = 3,024
13,068 + 3,024 = 16,092
cosA = 0.6
Using the Pythagorean identity
sin²A + cos²A = 1 ( subtract sin²A from both sides )
cos²A = 1 - sin²A ( take the square root of both sides )
cosA = ±
Since only the positive value is required , then
cosA =
=
= 0.6
