Use the Intermediate Value Theorem to show that there is a root of the given equation in the specified interval. ex = 3 − 2x, (0

raketka [301]

Answer:

$f(0)=-2\\f(1)=e-1$

Step-by-step explanation:

According to intermediate value theorem, if a function is continuous on an interval $[a,b]$ , and if $k$ is any number between $f(a)$ and $f(b)$ , then there exists a value, $x=m$ , where $a$ , such that $f(m)=k$

In the given question,

Intermediate Value Theorem is used to show that there is a root of the given equation in the specified interval.

Here,

$f(x)=e^x-3+2x$

Put $x=0$

$f(0)=e^0-3+2(0)=1-3+0=-2$

Put $x=1$

$f(1)=e^1-3+2(1)=e-3+2=e-1$

The measure of an interor angle of a regular polygon is given. Find the number of sides in the polygon.

EleoNora [17]

Let side be n

#1

$\\ \sf\longmapsto 120n=(n-2)180$

$\\ \sf\longmapsto 120n=180n-360$

$\\ \sf\longmapsto -60n=-360$

$\\ \sf\longmapsto n=6$

#2

$\\ \sf\longmapsto 160n=(n-2)180$

$\\ \sf\longmapsto 160n=180n-240$

$\\ \sf\longmapsto -20n=-240$

$\\ \sf\longmapsto n=12$

#3

$\\ \sf\longmapsto 144n=(n-2)180$

$\\ \sf\longmapsto 144n=180n-360$

$\\ \sf\longmapsto -36n=-360$

$\\ \sf\longmapsto n=10$

The cost of three tickets to a movie is at least $20. Select an inequality that represents the cost x (in dollars) of each ticke

SVETLANKA909090 [29]

Answer:

$x\geq \$6.67$

Step-by-step explanation:

Let

x------> the cost of each ticket

we know that

$3x\geq 20$ ----> inequality that represent the situation

solve for x

Divide by 3 both sides

$x\geq 20/3$

$x\geq \$6.67$

What is the slope of the line that passes through the points (-2, 2), and (-4, -2)? - 2 -2

dusya [7]

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-2, 2) and (-4, -2). Substitute:

$m=\dfrac{-2-2}{-4-(-2)}=\dfrac{-4}{-2}=2$

<h3>Answer: the slope = 2</h3>
