Answer:
<em>summation of five times negative three to the power of n from n equals zero to infinity</em>
Step-by-step explanation:
<u>Summation Notation
</u>
It represents the sum of a finite or infinite number of terms. Let's analyze the terms of the given succession:
5-15+45-135+...
If we take 5 as a common factor, we have
5(1-3+9-27+...)
The parentheses contain the alternate sum/subtraction of powers of 3. The odd terms are positive, the even terms are negative, thus the exponent must be n starting from 0 or n-1 starting from 1
The summation is then represented by

This corresponds with the option:
<u>summation of five times negative three to the power of n from n equals zero to infinity</u>
Y=mx+b
m=0.5
b is value of y in y-intercept, b=-2
The equation of this line is
y=0.5x-2
When x=4
y=0.5x-2=y=0.5*4-2=2-2 = 0
When x=4, y=0.
Answer:
Her model is 37 times as tall as Ben's.
Step-by-step explanation:
70 11/12 ÷ 5 3/4
851/12 ÷ 23/4
851/12 x 4/23
37/1 x 1/1 = 37 times as tall
