Answer:x=2; second option
Step-by-step explanation:
120+10x=140
10x=20
X=2
Given:
The table of values of an exponential function.
To find:
The missing values in the exponential function.
Solution:
The general exponential function is defined as:
...(i)
Where, a is the initial value and b is the growth factor.
First point from the given table is (1,10). It means, the equation (i) must be true for (1,10).
...(ii)
Second point from the given table is (2,20). It means, the equation (i) must be true for (2,20).
...(iii)
Dividing (iii) by (ii), we get


Putting
in (ii), we get



Putting
in (i), we get

The required exponential function for the given table of values is
. So, the missing values are 2 and x, where 2 is in the base and x is in the power.
Answer:
C
Step-by-step explanation:
The correct answer is C, -1. This is because slope formula is y2-y1/x2-x1. When you put that in you get 3-7/2-(-2) which equals -4/4, or -1.
Answer:
The profit for January is $57,200.
Step-by-step explanation:
The total profit for the two months would be the result of adding up the profit in January plus the profit in February:
Total profits=Profit in January+Profit in February
Also, you can say that profits in January can be represented by x and you know that the profit for a company in February was 15% higher than it was in January which can be expressed as: 1.15x. Moreover, you know that the total profit for the two months was $122,980. Now, you can replace the values on the formula:
122,980=x+1.15x
Now, you can solve for x:
122,980=2.15x
x=122,980/2.15
x=57,200
According to this, the answer is that the profit for January is $57,200.
The domain, or the distance traveled, is all real numbers from 10 to 30, inclusive. the answer is A
