Answer:

The expression is equal to 12.

Step-by-step explanation:

$-24-(18 / 6)*(-12)$

First of all, compute the parenthesis.

18 / 6 = 3

Now, replace 18/6 with 3 in our expression.

$-24-(18 / 6)*(-12)$

$-24-(3)*(-12)$

Next, compute the multiplication.

-12 * 3 = -36

Again, we'll replace that multiplication with negative 36:

$-24-(3)*(-12)$

$-24-(-36)$

Since subtracting a negative number is the same as adding a positive number:

$-24-(-36) = -24+36$

Compute the addition:

$-24+36=12$

$-24-(18 / 6)*(-12) = 12$

Answer: The expression is equal to 12.

In traveling across flat land, you see a mountain directly in front of you. Its angle of elevation (to the peak) is 3.5°. After

yaroslaw [1]

The height of the mountain is 0. 2 km

<h3>How to determine the height</h3>

First, let's find the hypotenuse of the second triangle

Using the tangent identity, we have;

tan θ = opposite/ adjacent

tan 3. 5 = x/ 19

cross multiply

x = tan 3 . 5 × 19

x = 0. 061 × 19

x = 1. 16 km

Now, we have the hypotenuse side of the second triangle and we need to find the opposite side which is the height of the mountain

Using the sine identity:

sin 9 = y/ 1.16

cross multiply

y = sin 9 × 1. 16

y = 0. 1564 × 1. 16

y = 0. 18 km

y = 0. 2 km in one decimal place

Thus, the height of the mountain is 0. 2 km

A. Use the Pythagorean theorem to calculate the length of segment AC. Show your work for credit.

Solnce55 [7]

alright so first ur trying to find adjacent so use cos which is adjacent/hypotenuse you know the angle of c is 90 because it is a right angle

so it gonna be

cos(90)= AC/5

5*cos(90)= AC

5*0=AC

side AC = 0

What are the coordinates for point A

polet [3.4K]

Answer:

(4, -2)

Step-by-step explanation:

You first go to the x axis (The one going left and round). From this, you can see the point is on 4 for the x axis. After that, you look at the y axis (The one going up and down). From this, you can see it is -2. In all, you put it in coordinate form which gives you (4, -2). I hope this helps you!

Terrence and Lee were selling magazines for a charity. In the first week, Terrance sold 30% more than Lee. In the

Rus_ich [418]

<em><u>Lee sold 40 magazines</u></em>

Step-by-step explanation:

Equation Model:

Let m be the number of magazines Lee sold.

150%-130%=20%, so if 0.2m=8 then m=40

Let me show another way: In the image above 20% is equal to 8 so if we use 8 and 20% and try to reach our way up to 100% (How much Lee sold in total) then we will get our answer.

20%=8

40%=16

60%=24

80%=32

100%=40

Therefore Lee sold 40 magazines.

Hope that makes sense! If you have any more questions or need further clarification then please comment down below or message me! Good luck!

What is the average rate of change of the function over the interval x = 0 to x = 8?

salantis [7]

Ans: The average rate of change of function = $\frac{1}{102}$ (in fraction)

Explanation:
The average rate of change of function = $\frac{f(b) - f(a)}{b - a}$

Where
b = 8 (x's upper bound)
a = 0 (x's lower bound)

$f(b) = f(8) = \frac{2*8-2}{5*8-6} = \frac{7}{17} \\ f(a) = f(0) = \frac{2*0-2}{5*0-6} = \frac{1}{3} \\ \frac{f(b) - f(a)}{b-a} = \frac{ \frac{7}{17} - \frac{1}{3}}{8} = \frac{1}{102}$

Hence the average rate of change of function = $\frac{1}{102}$ (in fraction)
