Answer:
f'(9) = 6
Step-by-step explanation:
f(x) = 6x+7
The derivative is
f'(x) = 6
Evaluated at x=9
f'(9) = 6
Answer:
after 75 minutes
Step-by-step explanation:
The least common multiple (LCM) of 15 and 25 is 75. It can be found a couple of ways:
1. List the factors of each number and find the product of the unique ones:
15 = 3·5
25 = 5²
The LCM is 3·5² = 75.
__
2. Find the greatest common divisor (GCD) and divide the product of the numbers by that value. From the above list of factors, we see that 5 is the GCD of 15 and 25. Then the LCM is ...
15·25/5 = 75
__
Or, you can simply list multiples of each number and see what the smallest number is that is in both lists:
15, 30, 45, 60, <em>75</em>, 90
25, 50, <em>75</em>, 100
__
The two buses will appear together again after 75 minutes.
It’s used to correct statistical averages that include obvious imbalances because of outliers in the data set.
Answer: $1296
Step-by-step explanation:
Surface area of s sphere = 4πx r^2
Diameter = 1/2 radius
Surface area = 4π x 12^2
= 1809.56 cm^2 = 18.096 m^2
Material required = 71.62 x 18.096
= $1296
