Trigonometry, can anybody help??
WINSTONCH [101]

Answer:

angle B: 39

AC: 7.288

AB: 11.58

(note: you cut off the part about rounding so make sure that it's rounded correctly before you put in your answer)

Step-by-step explanation:

To solve this we will use SOH, CAH, TOA

we have the angle and the one opposite to it which means we can use either SOH or TOA

let's use TOA

tan(51)=(9/x)

x= 7.288

We can now use pahtagaryous theroem to solve for the hyptonouse

we have

9²+7.288²=C²

C=11.58

Finally, to find angle B we will recall that the angles of a triangle must add to 180.

51+90+a=180

a=39

What are the domain and range of the function f(x) = x^4-2x^2-4 ?
tatuchka [14]

Answer:

Think about what domain and range is. Domain is the x and range is the y.

Step-by-step explanation: What values of x can you put in this function? Is there any number you cannot use?? Then what y's will you get back? The best way to find out might be to graph it to look. Since it is an even function whose ends go up, all the y's will be greater than or equal to the y value of the vertex.

Write an equation of the line that is parallel to y=1/2x+3 and passes through the point (10,-5)
Brut [27]

Answer:

13

Step-by-step explanation:

                                                                   x    y

y=1/2x+3 and passes through the point (10,-5) 10 = x and -5 =y    1/2(10) - this mean times

-5 = 1/2(10) +3

1/2(10/1) = 1 x 10 and 2 x 1 = 10/2 = 5

-5 = 5 + 3 = 7

-5 = 7          + 5 + 7

+5  +5

= 13

(I wish You'll understand)

In November, the rain in a certain valley tends to fall in storms of several days duration. The unconditional probability of rai
Mumz [18]

Answer:

0.0594 = 5.94% probability of rain on November 1 and 2, but not on November 3.​

Step-by-step explanation:

Rain on November 1:

0.9 of 0.6(rain on Oct 31).

0.3 of 0.4(not rain on Oct 31).

Rain on November 2:

Considering rain on November 1, 0.9 probability of rain.

Rain on November 3:

Considering rain on November 2, 0.1 probability of rain.

Find the probability of rain on November 1 and 2, but not on November 3.​

Multiplicating the probabilities:

p = (0.9*0.6+0.3*0.4)*0.9*0.1 = 0.0594

0.0594 = 5.94% probability of rain on November 1 and 2, but not on November 3.​

Select all of the roots of x3 2x2 – 16x– 32. –1 –2 –4 1 4 5
Lena [83]

In order to find the<u> roots</u> of the cubic equations by <u>graphing</u> you have to follow those steps

we have

x^3+2x^2-16x-32

we know that

The <u>roots</u> of the function are the values of x when the value of the function is equal to zero

Using a <u>graphing </u>tool

see the attached figure

The<u> roots</u> are

x=-4\ x=-2\ x=4

therefore

the answer is

x=-4\ x=-2\ x=4
