The correct Option is (D) <span>y = -0.15x + 1.95

Explanation:
The linear (line) equation is:
y = mx + c

Where
m = slope = rise/run = -0.3/2 = -0.15 (negative sign indicates the downward slope)
c = y-intercept = 1.95 (in graph)

Plug in the values in line equation:
y = -0.15x + 1.95 (Option D)</span>

The sum of the infinite geometric series is -288.

<h2>Given that</h2>

A finite geometric series with n = 4, a₁ = -144, and r = ½.

<h3>We have to determine</h3>

What is the sum of the infinite geometric series?

<h3>According to the question</h3>

The sum of the infinite is determined by the following formula;

$\rm S\infty = \dfrac{a_1(1-r^n)}{1-r}\\\\$

A finite geometric series with n = 4, a₁ = -144, and r = ½.

Substitute all the values in the formula;

$\rm S\infty = \dfrac{a_1(1-r^n)}{1-r}\\\\S\infty = \dfrac{-144 (1- \dfrac{1}{2}^4)}{1-\dfrac{1}{2}}\\\\S \infty = \dfrac{-144 \times \dfrac{15}{16}}{\dfrac{1}{2}}\\\\S \infty = -270$

Therefore,

The sum of the infinite geometric series is,

$\rm S = \dfrac{a_1}{1-r}\\\\S=\dfrac{-144}{1-\dfrac{1}{2}}\\\\S = \dfrac{-144}{0.5}\\\\S = -288$

Hence, the sum of the infinite geometric series is -288.

What is the circumference if the diameter is 21in and pi is 22/7

Ede4ka [16]

Answer:

66 in

Explanation:

the circumference can be calculated as:

$C=d\cdot\pi$

Where d is the diameter and π is 22/7.

So, replacing the values, we get:

$C=21\cdot\frac{22}{7}=\frac{21\cdot22}{7}=\frac{462}{7}=66\text{ in}$

Therefore, the circumference is 66 in.
