Answer:
Option B) There is a 3 percent increase in the savings account each year.
Step-by-step explanation:
we have
This is a exponential function of the form
where
M(x) represent the amount of money in a saving account
x represent the number of years
a is the original deposit (y-intercept)
b is the base
r is the rate or percent increase
The percent increase per year is the base of the exponential function decreased by 1.
so
In this problem we have
---> original deposit
Therefore
The percent increase per year is 3%
Answer:
80
Step-by-step explanation:
The three angles of a triangle add to 180 degrees. One angle is 10, the second is a right angle( which is 90 degrees). Let the third angle be x
10 +90 +x = 180
Combine like terms
100 +x =180
Subtract 100 from each side
100-100 +x= 180-100
x = 80
Answer:
You can use Pythagoras theorem to calculate x:
12² + 14² = x²
144 + 196 = x²
x² = 340
x = √340 ≈ 18,44
Ummmmmmm yeah..what is this
Triangle has a total of 180 degrees
add up all angles
A+B+C = 3x+5+4x-2+2x+6=180
9x=171
x=19
Plug x values into the A , B and C expressions and you get your answers
