Help please ASAP!!

Fittoniya [83]

Answer:

$\displaystyle 702$

Step-by-step explanation:

we are given a exponential function

$\displaystyle f(x) = {3}^{x + 1} - 22$

where x represents the number and f(x) represents the amount

we are also given that when x is 3 then f(x) is 59 likewise when x is 6 then f(x) is 2165

to figure out the average rate of change between 3 and 6 we can consider the average rate of change formula given by

$\displaystyle m = \frac{ f(x)_ {2} - f(x)_{1} }{ x_{2} - x_{1} }$

substitute what we have:

$\displaystyle m = \frac{ 2165 - 59 }{6 - 3 }$

simplify substitution:

$\displaystyle m = \frac{2106 }{3 }$

simplify division:

$\displaystyle m = 702$

hence, the average rate of change between 3 and 6 is 702

A regular triangular pyramid has a base area of 31.5 mm2 and a surface area of

Virty [35]

Answer:

A) 220.5 mm^2

Step-by-step explanation:

Explanation:-

Given A regular triangular pyramid has a base of area is 31.5mm^2

and also given surface area of triangular pyramid is 252 mm ^2

by using formula

surface area of regular triangular pyramid = base of area + half of lateral surface.

$surface area = area of the pyramid X \frac{1}{2} lateral surface$

252 = 31.5 + $\frac{1}{2} lateral surface$

$252-31.5= \frac{1}{2} lateral surface$

220.5 = lateral area of triangular pyramid

lateral area of triangular pyramid = 220.5 mm^2

The set of points P(0, 3), Q(2, 0), R(4, -3) are collinear and the line has a slope of _____.

vampirchik [111]

Answer:

slope = -1.5

Step-by-step explanation:

A set of three or more points are said to be collinear if they all lie on the same straight line.

We have been given the following collinear set of points;

P(0, 3), Q(2, 0), R(4, -3)

This implies that P, Q, and R lie on the same line.

The slope of a line is defined as; (change in y)/(change in x)

Using the points P and Q, the slope of the line is calculated as;

(0-3)/(2-0) = -3/2 = -1.5
