The missing parts of the table for the function are 49, 1 and 49 respectively

<h3>How to complete the missing parts of the table?</h3>

An exponential function is a type of function which involves exponents. A simple exponential function is of the form y = bˣ

Given:  the exponential function y = (1/7)ˣ

In order to find the missing parts, we have to substitute the relevant values into the function. Thus:

For x = -2:

y = (1/7)ˣ

Substitute x = -2 into the function:

y = (1/7)⁻² = 49

For x = 0:

y = (1/7)ˣ

Substitute x = 0 into the function:

y = (1/7)⁰ = 1

For x = 2:

y = (1/7)ˣ

Substitute x = 2 into the function:

y = (1/7)² = 1/49

The missing part is 49

Therefore, the missing parts of the table are 49, 1 and 49 respectively

never [62]

Answer:

$618.80

Step-by-step explanation:

If the tablet is on sale for 15% off, you pay 85% of the original price.

85% of $700 is

700(0.85) = $595

You pay 4% sales tax on $595, which is

$595(0.04) = $23.80

The total cost you pay is $595 + $23.80 = $618.80

n= number of terms-----30

 calculation of a1

a1=4n+1=4*1+1=5

 calculation of an

a30=4*30+1=121

 S30=(a1+a30)*30/2

S30=(5+121)*30/2=1890
