F (x) = 2x + 3; find f (–1)" (pronounced as "f-of-x equals 2x plus three; find f-of-negative-one"). In either notation, you do exactly the same thing: you plug –1 in for x, multiply by the 2, and then add in the 3, simplifying to get a final value of +1
Speed (S) = Distance (D) / time (t)
First stretch
45 = D / 2
D = 45*2
D = 90 mp
How is the same distance:
Second stretch
S = 90 / t
Average speed (AS):
AS = (S1+S2) / 2
60 = [45+(90/t)] / 2
120 = 45+90/t
120-45 = 90/t
75 = 90/t
t = 90/75
t = 1,2 h
________________________
And now:
S = 90 / t
S = 90 / 1,2
S = 75 mph
Answer:
13.75 servings or 13 ¾ servings
Step-by-step explanation:
This is the correct question
Stephen uses 2/25 kilograms of tofu in each serving of his famous tofu dish. He has 1 1/10 kilograms of tofu.
To get answer
We will have to divide the number of tofu required with the number of tofu own.
Stephen uses 2/25 kilograms of tofu in each serving and he has 11/10 kilograms tofu.
= (11/10) ÷ (2/25)
= (11/10) ÷ (2/25)
11/10 * 25/2 =
275 ÷ 20= 13.75 servings or 13 ¾ servings
Stephen can make 13 ¾ or 13.75 servings
Answer:
yeah
Step-by-step explanation:
Answer: 77.05
Step-by-step explanation: 1) Draw a right triangle with these measures:
angle with the horizontal: 6 degress
horizontal segment: 5
height: x
2) Definition of tangent : tan(6°) = opposite leg / adjacent leg = x / 5 =>
3) Solve for
x = 5tan(6°) = 77.05
