For the right triangles below, find the exact values of the side lengths c and d.
If necessary, write your responses in simplified radical form.

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:

Step-by-step explanation:

cos 31=w/12

0.8571=w/12

w=12x0.8571

w=10.28

w to nearest tenth= 10.3

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!!!!

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".

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

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:

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:

x = 3√5

Step-by-step explanation:

we can use the Pythagorean Theorem twice, first to find the longer leg of the left triangle:

7² + b² = 10²

b² = 100-49

b² = 51

b = √51 which we can simplify to be √9·√3·√3 = 3·3 = 9

we can use the Pythagorean Theorem next to find 'x':

x² + 6² = 9²

x² + 36 = 81

x² = 45

x = √45 = √9·√5 or 3√5
