Answer:

<h2>-2 units per unit increase in x</h2>

Step-by-step explanation:

The average rate of change of a function f(x) on a given interval [a, b] is:

f(b) - f(a)

a. r. of c. = ----------------

b - a

Here a = -1 and b = +1. The function f(x) is given graphically. Note how f(a) = f(-1) = 4 and how f(b) = f(+1) = 0.

In this case, the a. r. of c. is:

0 - 4 -4

a. r. of c. = ---------------- = ---------- = -2 units per unit increase in x

1 - (-1) 2

If each of the following represents the slope of a line (or line segment), give the slope a line that is perpendicular to it. (a

Crank

Answer:

$m_2 = -\frac{3}{4}$ -- (a)

$m_2 = -\frac{7}{3}$ -- (b)

$m_2 = -\frac{1}{4}$ --- (c)

$m_2 = -3$ -- (d)

Step-by-step explanation:

Given

$a.\ m = \frac{4}{3}$

$b.\ m = \frac{3}{7}$

$c.\ m = 4$

$d.\ m = \frac{1}{3}$

Required

Determine the slope of a perpendicular line

In geometry, the condition for perpendicularity is:

$m_2 = -\frac{1}{m}$

This formula will be applied in solving these questions.

$a.\ m = \frac{4}{3}$

$m_2 = -\frac{1}{m}$

Substitute 4/3 for m

$m_2 = -\frac{1}{4/3}$

Express as a proper division

$m_2 = -1/ \frac{4}{3}$

Convert to *

$m_2 = -1* \frac{3}{4}$

$m_2 = -\frac{3}{4}$

$b.\ m = \frac{3}{7}$

$m_2 = -\frac{1}{m}$

Substitute 3/7 for m

$m_2 = -\frac{1}{3/7}$

Express as a proper division

$m_2 = -1/ \frac{3}{7}$

Convert to *

$m_2 = -1* \frac{7}{3}$

$m_2 = -\frac{7}{3}$

$c.\ m = 4$

$m_2 = -\frac{1}{m}$

Substitute 4 for m

$m_2 = -\frac{1}{4}$

$d.\ m = \frac{1}{3}$

$m_2 = -\frac{1}{m}$

Substitute 1/3 for m

$m_2 = -\frac{1}{1/3}$

Express as a proper division

$m_2 = -1/ \frac{1}{3}$

Convert to *

$m_2 = -1* \frac{3}{1}$

$m_2 = -\frac{3}{1}$

$m_2 = -3$

A manufacturing company produces two sizes of cylindrical containers that each have a height of 50 centimeters. The radius of Co

ira [324]

Answer:

Volume of B=62800 $cm^3$

Step-by-step explanation:

We are given

Height = 50 cm

Radius of A=16cm

Radius of Cylinder B is 25% more than that of A

Radius of B = 16 + $\frac{25}{100}*16$ cm =16+4= 20 cm

Volume of cylinder B = $pi*r^2*h$

= $3.14 * (20)^2*50$

=62800 $cm^3$

PLEASE SOMEONE HELP IM SO CLOSE TO BEING DONE FOR THE YEAR <br> NO LINKS OR FILES

8_murik_8 [283]

Answer:

Step-by-step explanation:

The negative out front only tells us which way the parabola will open. That means that the first one will open upside down, since it's got a negative out front. The value of the number that serves as the leading coefficient (the number stuck to the x-squared) determines how steep or wide-open the parabola's shape is. The leading coefficient in the first one is a 1, so it opens up exactly as wide as its parent graph does. The leading coefficient in the second one, a 2, means that the parabola will be skinnier or narrower than its parent. If the leading coefficient is greater than 1, the parabola will be narrower than its parent; if the leading coefficient is greater than 0 but less than 1, the parabola will open wider than its parent.
