Answer:
The population after 15 years will be 
Step-by-step explanation:
In this problem we have a exponential function of the form
where
a is the initial value
b is the base
r is the rate
b=(1+r)
x ----> the number of years
f(x) ----> the population
we have
The equation is
For x=15 years
substitute the value of x
therefore
The population after 15 years will be
There will be fourty-three tens and three ones. Nut since you only need the tens, just put fourty-three
Answer:
A= 1000(1+.06)^3 answer is A=1191.016
Step-by-step explanation:
first the formula is A=a(1 + or- R)^t
A=total
a=money or amount
R=rate it increase or decrease (percent) change to decimal
T=times,years,months ect..
-6(-3)=18, so that is true
-6+(-3)=-6-3=-9 so that is true
-6-(-3)=-6+3=-3 FALSE
-6 ÷ (-2)=2 so that is true
Answer is C
Answer:
70 degrees
Step-by-step explanation:
Supplementary means the angles add up to 180 degrees. We can set up an equation using this:
9x+20+6x+10=180
Combine like terms.
15x+30=180
Isolate variable.
15x=150
x=10
Substitute in the variable for the expression of angle B
6(10)+10=70
Hope this helps!
