Answer:
-5 degrees
Step-by-step explanation:
-10+5= -5
Answer:
The growth factor b is 1.04
Step-by-step explanation:
we know that
In this problem we have a exponential function of the form
![y=a(b^x)](https://tex.z-dn.net/?f=y%3Da%28b%5Ex%29)
where
y ---> is the number of students enrolled at a college
x ----> the number of years
a is the initial value or y-intercept
b is the growth factor
b=(1+r)
r is the rate of change
we have
![a=15,000\ students](https://tex.z-dn.net/?f=a%3D15%2C000%5C%20students)
![r=4\%=4/100=0.04](https://tex.z-dn.net/?f=r%3D4%5C%25%3D4%2F100%3D0.04)
![b=1+0.04=1.04](https://tex.z-dn.net/?f=b%3D1%2B0.04%3D1.04)
therefore
The exponential function is equal to
![y=15,000(1.04^x)](https://tex.z-dn.net/?f=y%3D15%2C000%281.04%5Ex%29)
Answer:
5
Step-by-step explanation:
200% × x = 20. x = 10. 50% of a number = 50% × 10 = 50÷100×10 = 0.5 × 10 = 5.
I think that the best answer is A
Answer:
first term = 3
Step-by-step explanation:
The n th term of a GP is
= a₁![(r)^{n-1}](https://tex.z-dn.net/?f=%28r%29%5E%7Bn-1%7D)
where a₁ is the first term and r the common ratio
Here r = 3 and a₅ = 243 , thus
a₁ ×
= 243
a₁ × 81 = 243 ( divide both sides by 81 )
a₁ = 3
