Answer:
(c) Equation which can be used to find r, the cost in dollars to park s nights is r = 24.99 s
Step-by-step explanation:
Here, the parking cost of 1 night at the airport = $24.99
Now, here the total number of nights the car is parked at airport = s
R = The total cost of parking s nights
Now, The cost for parking s nights = s x ( Cost of parking 1 night)
= s x ($24.99) = 24.99 s
Also the cost for parking s nights = r
⇒ r = 24.99 s
Hence, equation which can be used to find r, the cost in dollars to park s nights is r = 24.99 s
Answer: $142.5
Step-by-step explanation: If the price is being marked up by 50%, you take 50% or half of the original price of $95, which is 47.5, and add it to your original price.
95 + 47.5 = 142.5
Answer:
The circumference of a circle is calculated by multiplying the diameter of a circle by π (π × d) . The formula to calculate the circumference of a circle is usually written c = πd .
Step-by-step explanation:
Pi is a number that is approximated by 3.14, or 22/7. It is the ratio of the circumference to the diameter of any circle. This ratio can be rearranged to find circumference of a circle by multiplying pi times diameter.
I hope this helps.
Answer:
f(x)=11+7√x
f'(x)=7/(2x^(1/2))
putting x=1
f'(1) = 7/(2×1^(1/2))
= 7/2 = 3.5
putting x=2
f'(2) = 7/(2×2^(1/2))
= 7/(2×√2)
= 7√2/4
= 2.47 (rounded to the nearest hundredth)
f'(3) = 7/(2×3^(1/2))
= 7/(2×√3)
= 7√3/6
= 2.02 (rounded to the nearest hundredth)
