Step-by-step explanation:

did it on graphing calc

The solution of the inequality is [0, 1.699].

We will graph y=cos(0.65x)-0.45 using a calculator. Image 1.

Then we draw the boundary x=0 and x=[tex]2\pi[/tex] on the same graph. And we try to find where y>0 on that graph. Image 2.

From the graph we see that y>0 that means cos(0.65x) > 0.45 is over the interval [0, 1.699].

Step-by-step explanation:

5x+52=9x+20

subtract 5x on both sides

subtract 20 on both sides

32=4x

divide by 4 on both sides

x=8

plug in x to the equations for A, D, and C

A and D are 92°

C is 56°

B and C will add up to 90, so

90-56=34°

13y-6=34

add 6 on both sides

13y=40

divide by 13

y=40/13 (I don't wanna calculate that)

Answers

Answer:

f(x) = 54

Step-by-step explanation:

Plugging in -8 we get f(x) = 6(1-(-8)) since there is a double negative we can simplify it to a positive --> f(x) = 6 (1 +8) now distribute 6 to all factors in ( )

6 times 1 is 6 and 6 times 8 is 48. So now we have 6 + 48 which = 54
