A ladder is propped up against the side of a building. The top of the ladder touches the building 40 feet above the ground. The bottom of the ladder is placed 10 feet from the base of the building. How long is the ladder? Round your answer to the nearest foot.

Answer:

a=1,b=3,c=10

Step-by-step explanation:

a= the number with the highest power, in this case it is x^2. Therefore, a=1.

b= the number with the second number, the one that has an x. Therefore, b=3.

c=the last number, the one with no variable. therefore, c=10

Answer:

x = 2

Step-by-step explanation:

because m || n, you can assume the two angles are congruent.

set them equal to each other:

5x - 4 = 4x - 2

solve

add 4 to both sides: 5x + (-4 + 4) = 4x + (-2 + 4) --> 5x = 4x + 2

subtract 4x from both sides: (5x - 4x) = (4x - 4x) + 2 --> x = 2

Step-by-step explanation:

So visually youre given the function

for h(-4) it can also be written as h(-4) = y

what do you get for y when you substitute - 4 for x?

All you have to do is trace the line until you get to x=-4 and then find the y that corresponds to it (looks like around y= - 1)

for the other one h(x) = - 5

what do you get for x when you substitute - 5 for y?

what you do is similar, trace the line along the y-axis and see what x-value you get for y =-5

Answer:

3 and x = 0

Step-by-step explanation:

To find the value of h(- 4)

Locate x = - 4 on the x- axis, go vertically up to meet the graph at (- 4, 3 )

Then the value of h(- 4) = 3

For h(x) = - 5

Locate y = - 5 on the y- axis. This is the point (0, - 5)

then the value of x for which h(x) = - 5 is x = 0

Answer:

$330

Step-by-step explanation:

to find how much he earned before raise:

1.2x = 1980

x = 1980/1.2

x = 1650

current salary: 1980

former salary: 1650

he makes $330 more

Answer:

330

Step-by-step explanation:

The error is when she added 4 to both sides.

Instead, she should divide both sides by -4 to undo the multiplication. Specifically, the multiplication between the -4 term and the (x-2)^2 term.

This is one possible correction of what her steps could look like.

[tex]y = -4(x-2)^2\\\\\\0 = -4(x-2)^2\\\\\\\frac{0}{-4} = \frac{-4(x-2)^2}{-4}\\\\\\0 = (x-2)^2\\\\\\(x-2)^2 = 0\\\\\\\sqrt{(x-2)^2} = \sqrt{0}\\\\\\x-2 = 0\\\\\\x-2+2 = 0+2\\\\\\x = 2\\\\\\[/tex]

In the third step, I'm dividing both sides by -4. In the sixth step, I'm applying the square root to both sides to undo the squaring operation. Then two steps later, I'm adding 2 to both sides to undo the "-2", which helps fully isolate x.

The only solution is x = 2, so it's the only x intercept. You can verify this answer by plugging x = 2 back into the original equation at the very top. You should end up with y = 0.

Note: The term "root" is another name for "x intercept".

Answer:

C=2

Step-by-step explanation:

Because I got it correct in AP3X

The value of C is 3 for the given graph.

The cosine function is a trigonometric function that's called periodic. In mathematics, a periodic function is a function that repeats itself over and over again forever in both directions.

According to the given problem,

Given, cosine function = Acos( x - C )  

where, A = amplitude

           C = Maximum and Minimum value of y

We know, a general cosine function is in the form of,

f(x) = Acos( x + C )

For the given graph, we need to take the minimum value of y,

⇒ C = -2  

⇒ f(x) = Acos( x - 2 )

Hence, we can conclude, for the given graph, the cosine function has to be Acos( x - 2 ), where the value of C is -3.

Answer:

1. tan(x) = 9/20

arctan(9/20) ≈ 24.23°

2. cos(x) = 17/32

arccos(17/32) ≈ 57.91°

3. tan(x) = 13/18

arctan ≈ 35.84°

4. sin(x) = 21/28

arcsin(21/28) ≈ 48.59°

Answer:

1    x = 24.2°

2    x = 57.9°

Step-by-step explanation:

You must memorize the definitions of the trig functions and then these problems are easy

1:   tan = opposite side/adjacent side

opp side to x is 9 and adjacent side is 20

So, tan x = 9/20

x = arctan (9/20) = 24.2°

2:   cos = adjacent side/hypotenuse

adjacent side = 17 and hypotenuse = 32

cos x = 17/32

x = arccos (17/32)

x = 57.9°

You do 3 and 4.  Hint:  Use the tan function in 3 and the sine function in 4

OK?   You can do it!!!!

Step-by-step explanation:

Smaller number = y (Given)

[tex] \because [/tex] Larger number - smaller number = 8

Answer:

Step-by-step explanation:

so theres 8 red marbles, 6 blue marbles, and 6 white marbles so that makes

8 + 6 + 6 = 20 marbles in total

the probability of the marble being white is 6/20 or 3/10

so the probabilty of the marble NOT being white is 1 - (3/10) = 7/10
