Answer:
Option A - The number of visitors is multiplied by (1+r) each year
Step-by-step explanation:
Given : The number of visitors to an art museum increases each year. The function V(t)=N(1+r)^t represents the number of visitors to the museum at year t, where N is the number of visitors in year 0 and r is the rate of increase.
To find : Select the correct statement?
Solution :
We have given an exponential function,
The function V(t)=N(1+r)^t represents the number of visitors to the museum at year t, where N is the number of visitors in year 0 and r is the rate of increase.
As In year 0,
The initial visitors is V(t)=N(1+r)^0=N
In year 1,
V(t)=N(1+r)^1=N(1+r)
In year 2,
V(t)=N(1+r)^2
So, According to this the number of visors is multiplied by (1+r) each year.
Therefore, Option A is correct.
Answer: The y intercepts are: ( 0, 20 )
Step-by-step explanation:
96°.
Since sides AB and AC ane equal, that means that angle B is equal to angle C. The measurement of all the angles of a triangle always equals 180°, so if you add angles B and C, you should get 84° and then you should be able to find angle A. Subtract 84° from 180° and you should get 96°.
Answer:
? = -2
Step-by-step explanation:
The division law of exponents states that when two numbers with the same base are divided, the exponents will subtract:
This means that the answer is:
Now we just need to convert the answer into the form the question needs.
The power of a power exponent law states that when an exponent is raised to an exponent, the exponent are multiplied, so:
This also means that
Since our <em>ab </em>is -10, we just need to divide it by the <em>a</em>, which is 5, to get our <em>b</em>, which is the ?
-10/5=-2
Therefore the ? = -2
