Answer:

It changes negative numbers to positive.

Step-by-step explanation:

Absolute value is the measure of a numbers distance from 0. You can't have negative distance, so absolute value of negative numbers is positive and absolute value of positive numbers is always positive. The absolute values of 5 and -5 are both 5 because they are both 5 units away from 0 on a number line, just in opposite directions.

What is 2/8 in simplest form

denis23 [38]

Ok, so you need to find something you can divide with both 2 and 8. You should get 2. 2 divided by 2 equals 1, and 8 divided by 2 equals 4.

So the simplest form of 2/8 is 1/4.

ANALYZE A PROBLEM Describe the x-values for which (a) f is increasing (b) f is decreasing, (c) f (x) > 0 and (d) f (x) < 0

Karolina [17]

The analysis of the graph, that has x-intercepts of (0, 2), and (0, 5), we get;

a. The function increases when x > 4

b. The function decreases when x < 4

c. The function is greater than zero when x < 3, and x > 5

d. The function is less than zero when 3 < x < 5

<h3>What is a point where a function is increasing?</h3>

The location of a point where a function is increasing is where the slope of the function is larger than zero.

The description of the graph of the function are as follows;

The shape of the function = Concave upwards

The coordinates of the vertex of the function = (4, -5)

The region where the function is decreasing is from -∞ to 4

The region where the function is decreasing is therefore; x < 4

At the vertex, (4, -5), the slope of the function is zero, therefore;

Therefore, the function is increasing where x > 4

The x-intercepts are at point (0, 3) and (0, 5)

Therefore, the function is greater than zero when x < 3, and when x > 5

The function is less than zero in the range 3 < x < 5

If y=80,when x=32 find x when y=100

Bess [88]

Y X
80 32
100 x'

80x' = 100*32
80x' = 3200
x' = 3200/80
x' = 320/8
x' = 40

Answer the photo below thanks

Crazy boy [7]

Answer:

307cm²

Step-by-step explanation:

This is a composite firgue so we need to split the two shapes, then find the area of both.

find the area of the rectangle

A=b*h

A=18*10

A=180

then find the area of the semicircle

A=1/2Pi*r²

A=1/2Pi*81

A=127.75 (We need to find the radius of the semicircle then square it)

then add the two areas 180+127.75=307.75

find the closet unit its

A sailboat leaves port and sails 12 kilometers west and then 9 kilometers north. The sailboat is now kilometers from port

Luden [163]

Answer: The sailboat is at a distance of 15 km from the port.

Step-by-step explanation: Given that a sail boat leaves port and sails 12 kilometers west and then 9 kilometers north.

We are to find the distance between the sailboat from the port in kilometers.

Since the directions west and north are at right-angles, we can visualize the movement of the sailboat in the form of a right-angled triangle as shown in the attached figure.

The sailboat moves leaves the port at P and reach O after sailing 12 km west. From point O, again it moves towards north 9 km and reach the point S.

PS = ?

Using the Pythagoras theorem, we have from right-angled triangle SOP,

$PS^2=OS^2+OP^2=9^2+12^2=81+144=225\\\\\Rightarrow PS=15~\textup{km}.$

Thus, the sailboat is at a distance of 15 km from the port.
