Answer:
Step-by-step explanation:
The opposite side to angle B is 4. It is the line AC. AC is not connected in any way to <B
The adjacent side is one of the two sides making up <B. It is 3.
Tan(B) = opposite / adjacent
Tan(B) = 4/3
<B = tan-1(4/3)
<B = 53.13
Answer:
4 weekdays and 2 weekends.
Step-by-step explanation:
6 days.
x = weekdays
y = weekends
7x = amount with weekdays
12y = amount with weekends
7x + 12y = 52, total
x + y = 6, amount of days
solve double variable equation
x = 6 - y, plug in to 1st equation
7(6 - y) + 12y = 52
42 - 7y + 12y = 52
5y = 10
y = 2 weekends
2 + x = 6
x = 4 weekdays
Answer:
Option b
Step-by-step explanation:
We have a compound interest problem. With an annual interest rate of 0.675 and an initial payment of 8500, with t = 25 years
Then you must use the annual compound interest formula, which is represented by a growing exponential function:

Where:
h is the interest rate of 0.675
y is the money in the savings account as a function of time
Then substitute the values in the formula and we have:


Divide 1017,36 by pi and by the height (the inverse of the formula for the volume):
1017,36/3,14 = 324
324/9 = 36
