Answer:
48
Step-by-step explanation:
given that c = 5 and d = 4?
so insert the value of c and d equals 5 and 4 respectively
6c2 – 5d + 8
6 (5) × 2 - 5 (4) + 8
30 × 2 - 20 + 8
60 - 20 + 8
40 + 8
48
Answer:
A
Step-by-step explanation:
Given sinP = =
Then the right triangle has a hypotenuse of 13 and a leg 5
Use Pythagoras' identity to find the other leg x ( adjacent)
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take the square root of both sides )
x = = 12 , hence
tanP = =
Answer:
18.
Step-by-step explanation:
6 * [13 - 2(4 + 1)] = 6 * [13 - 2(5)] = 6 * (13 - 10) = 6 * 3 = 18

72 kilometers per hour ÷ 60 (amount of minutes in an hour) = 1.2 kilometers per minute
1.2 kilometers per minute x 20 minutes = 24 kilometers
