Answer:
It annually drops by 20%
Step-by-step explanation:
30,000 multiplied by 20% is 6000. Subtract 6000 from 30,000 and you get 24,000. 24,000 multiplied by 20% is 4,800. Subtract 4,800 from 24,000 and you get 19,200. Etc.
Answer:
a) Is multiplied by the original exponent.
Step-by-step explanation:
the power rule works like this:
you want to find the derivative of ax
ⁿ
where n is the exponent and a is the coefficient
the derivative would equal (n ⋅ a)xⁿ⁻¹
e.g. you want to find the derivatives of 5x⁴
f'(x) = (4 ⋅ 5)x⁴⁻¹ = 20x³
f''(x) = (3 ⋅ 20)x³⁻¹ = 60x²
f'''(x) = (2 ⋅ 60)x²⁻¹ = 120x
f''''(x) = (1 ⋅ 120)x¹⁻¹ = 120
Answer:
b
The rest are at least 500 numbers away from 12
Step-by-step explanation:
Answer:
y=3x +25
Step-by-step explanation:
First calculate the slope:
m = (y1 - y2)/(x1-x2)
m = (49 - 13)/(8-(-4))
m= 36/12 = 3
so we have
y = 3x + b
subtitute a point:
49=3(8) + b
b=25
the equation is y=3x +25
the digit 8 is ten times the value of 6 in 786.
