Answer:

see explanation

Step-by-step explanation:

cos150°

= - cos(180 - 150)°

= - cos30°

= - \frac{\sqrt{3} }{2}

-------------------------

sin150°

= sin (180 - 150)°

= sin30°

= \frac{1}{2}

Answer:

See below in bold.

Step-by-step explanation:

cos 150 = - cos(180 - 150)

= - cos 30

= -√3/2.

sin 150

= sin (180 - 150

= sin 30

= 1/2.

Angle a will be 77 degrees because the total amount of the angles added up is 180. I added 68 and 35(103). Then subtracted my sum(103) by the to amount of a triangles angles(160). Which gave me 77

Answer:

-3x^2+16x+64

Step-by-step explanation:

First, you need to find the area of both areas (the total area and the area of the unshaded part). Let's find the total area.

(x+8)(x+8)=x^2+16x+64

The total area is x^2+16x+64

(2x)(2x)=4x^2

The area of the unshaded part is 4x^2

Now we have to subtract to find the area of the shaded part.

x^2+16x+64-4x^2

-3x^2+16x+64

That is the answer

Hope this helped!! :D

How are the graphs of the functions f(x) = /16x and g(x) = 3/64x related
seropon [69]

Answer:

the functions f(x) and g(x) are equivalent

Step-by-step explanation:

Your full question is attached below

The equations of your problem are

f(x) = √(16^x)

f(x) = √(4^(2x))

f(x) = √(4^(2x)) = √(4^x.4^x)

f(x) = 4^(x)

and

g(x) = ∛64^x

g(x) = ∛4^(3x)

g(x) = ∛4^(3x)  =  ∛4^(x) .4^(x) .4^(x)

g(x) = 4^(x)

Thus, the functions f(x) and g(x) are equivalent

How do you put 0.5, 1/5, 0.35, 12/25, 4/5 in order from least to greatest
nasty-shy [4]

1/5= 0.2

12/25= 0.48

4/5=0.8

12/15 would be the least, then 0.35, then 4/5, then 1/5 and 0.5 would be the greatest because it's one half.
