Answer:

about 0.31°

Step-by-step explanation:

First of all, solve for sin(2θ):

3000 = (1/32)(3000^2)sin(2θ)

32(3000)/3000^2 = sin(2θ)

4/375 = sin(2θ) . . . . . . . simplify

Now, we find the corresponding angle:

2θ = arcsin(4/375) ≈ 0.61117°

θ ≈ 0.30558° ≈ 0.31°

The angle of elevation must be about 0.31°.

Answer:

#1.---60% #2.---$12.60 per hour

Step-by-step explanation:

#1. Since It was originally $50 you have 50% already, so what I did was I multiplied 50 by 2. this got me 100 which is a simpler way to calculate by. 50 to 80 dollars is a $30 change, so multiply that by 2 and you get 60. 60 will be your percent of change. You can double check this by multiplying 50 by .60, the answer will be 30 and 50+30=80

#2 Since Tyler starts off with $12 per hour with a 5% increase you will need to multiply 12*.05 this will get you the answer of 0.6 you then need to add $12, since that was his original payment. 12+0.6=12.60, so his final payment would by $12.60 per hour

write the slope-intercept form of the line with a slope of 2 and a y-intercept of -4. include your work in your final answer.

I cant really show you how to graph this but i can try to explain it. you would make a 4 quadrant graph and do rise over run.
1)start by making the graph
2) on the line of the graph marked Y is where you would put -4
3) From -4, you would go up (rise) by 2 and go over to the right 1 where you end is the slop
