From the question we have that f(x) = -1/2 sin 5x and g(x) = 4 sin5x
Let's try to calculate -8f(x)
- 8f(x) = -8 (-1/2 sin 5x)
This becomes 4sin 5x
Since the function g(x) is -8 times f(x)
Hence g(x) = -8f(x)
Answer: 48 pounds
Step-by-step explanation:
Given: A person who weighs 240 pounds burns 180 calories per mile of running.
There is a direct relation ship between the weight of the person and the calories burn.
If a person burns thirty-six calories by running one mile.
Let x be the weight of the person then
The weight of the person is 48 pounds.
Answer:
Semicircle = 353.25 cm²
Step-by-step explanation:
Area of semicircle = πr²/2
substitute the values
semi circle = 3.14 × 15 × 15 / 2
Area of semicircle = 353.25 cm²
Answer:
-15
Step-by-step explanation:
x-1/2(x+5)=-10
x-1/2x-5/2=-10
2/2x-1/2x-5/2=-10
1/2x-5/2=-10
1/2x=-10+5/2
1/2x=-20/2+5/2
1/2x=-15/2
x=(-15/2)/(1/2)
x=(-15/2)(2/1)
x=-15/1
x=-15
