Answer:

2.5

Step-by-step explanation:

I used the process of elimination :

For A and B, you can't have a negative number since it is a positive correlation

For C, 1 as a slope isn't reasonable

How To Round 17 5/8 To The Nearest Whole Number

Verdich [7]

Answer:
18

Explanation:
To round a number to the nearest whole number, we would check the fraction part:
If the fraction is less than 0.5, then we would simply ignore the fraction
If the fraction is equal to or more than 0.5, then we would add 1 to the whole number and eliminate the fraction.

In the given , we have:
 $17 \frac{5}{8}$ .

The fraction part is $\frac{5}{8}$ which is greater than 0.5
This means that we would add one to the whole number (round it up) and eliminate the fraction.
Therefore, the answer would be 18.

Hope this helps :)

If f(x) = 2x2 + 1 and g(x) = x2 - 7, find (f + g)(x).

pishuonlain [190]

Answer:

(f+g)(x) = $3x^{2} - 6$

Step-by-step explanation:

First, lets understand what (f+g)(x) means.

(f+g)(x) is when you are taking the values in the function f(x) and adding it to the values in the function g(x).

So, this is what the equation looks like when you substitute the functions in to (f+g)(x):

(f+g)(x) = $(2x^{2} +1) + (x^{2} -7)$

Now, combine like terms and Simplify:

(f+g)(x) = $3x^{2} - 6$

This is your final answer.

A sequence is shown.

marin [14]

Answer:

Step-by-step explanation:

The given sequence of numbers is increasing in geometric progression. The consecutive terms differ by a common ratio, r

Common ratio = 6/3 = 12/6 = 2

The formula for determining the nth term of a geometric progression is expressed as

Tn = ar^(n - 1)

Where

a represents the first term of the sequence.

r represents the common ratio.

n represents the number of terms.

From the information given,

a = 3

r = 2

The function, f(n), representing the nth term of the sequence is

f(n) = 3 × 2^(n - 1)
