1 answer:

4 0

To find the common ratio, divide the 2nd term by the first term
-16 / 32 = -0.5....this means u multiply each number by -0.5 to find the next number

8 * -0.5 = -4 <==
-4 * - 0.5 = 2 <==
2 * -0.5 = -1 <==

A paperweight is shaped like a triangular pyramid. The base is an equilateral triangle. Find the surface area of the paperweight

stich3 [128]

Answer:

The surface area of the paperweight is $SA=8.3\ in^2$

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to the area of its triangular base plus the area of its three triangular lateral faces

<em>Find the area of its triangular base</em>

$SA=\frac{1}{2}(2)(1.7)$

$SA=1.7\ in^2$

<em>Find the area of its three triangular lateral faces</em>

$SA=3[\frac{1}{2}(2)(2.2)]$

$SA=6.6\ in^2$

Adds the areas

$SA=1.7+6.6$

$SA=8.3\ in^2$

Jake is studying a small insect population for his science fair project. In the mornings before school he records the insect pop

Masja [62]

Using it's concept, it is found that the average rate of change of this function over the interval of time from 30 days to 60 days is of 0.4 insects per day.

<h3>What is the average rate of change?</h3>

The <em>average rate of change</em> of a function f(x) over an interval [a,b] is given by the <u>change in the output divided by the change in the input</u>, that is:

$A = \frac{f(b) - f(a)}{b - a}$
