Answer:
1353.13
Step-by-step explanation:
1250*.0825= 103.125+1250= 1353.125
then round to the hundredths place to get 1353.13
You have to get 8.25% to a fraction to be able to multiply move the decimal point to the left twice.
He didn't distribute 1/3 to x and 15 before solving
The first derivitive is the slope
a positive 1st deriviive is positive slope or increasing
a negaitve 1st derivitive is negative slope or decreasing
the 2nd derivitive tells about the concavity
a negative second derivitive means it is concave down at that point
a positive 2nd derivitive means it is concave up at that point
so
first one is false
2nd is true
3rd is false because it could possibly be a minimum as well
answer is 2nd one
Answer:
5√202
Step-by-step explanation:
By Pythagoras theorem,
x^2 = 45^2 + 55^2
= 2025 + 3025
x^2 = 5050
x = 5√202
m = money earned in one week
h = hours worked
x = times credit card was swiped
m = 14.45h + 8.50x
