An employee’s new salary is $26.355 after getting a 5% raise. What was the salary before the increase pay?

Serga [27]

Answer:

$25.03725

Step-by-step explanation:

<u>Step 1: Multiply both sides by %5 to get the raise</u>

26.355 * %5 is same as 26.355 * 0.05

$1.31775 is the raise

<u>Step 2: Subtract the raise from the new salary</u>

26.355 - 1.31775

25.03725

Answer: $25.03725

Does this table represent an exponential function? x 1 2 3 4 y 4 16 64 256

4vir4ik [10]

Answer:

Yes, the given table represent an exponential function.

Step-by-step explanation:

Given table is :

x y

1 4

2 16

3 64

4 256

Now we need to identify if the given table represent an exponential function or not. To find that we need to check if we can write the numbers in y-column in form of exponential function $y=ab^x$ .

We see that y-values are basically powers of 4 so we can write the related function as $y=4^x$ .

Which is clearly in form of $y=ab^x$ .

Hence yes, the given table represent an exponential function.
