Answer:
745.5 ft
Step-by-step explanation:
Reference angle (θ) = angle of depression = angle of elevation = 28° (alternate angles are congruent)
Opposite side = 350 ft
Hypotenuse = x
Apply the trigonometric function, SOH:
Sin θ = Opp/Hyp
Sin 28° = 350/x
x = 350/Sin 28
x = 745.5 ft (nearest tenth)
Answer: a.) Slope-intercept form: y = 1/2x + 3
Standard form: x - 2y = -5
b.) ??
c.) Slope-intercept form: y - 5 = 3/4 · (x - 4)
Standard form: 3x - 4y = -8
d.) Slope-intercept form: y - 1 = 3 · (x - 2)
Standard form: 3x - y = 5
If any of these are wrong i'm sorry but i'm pretty sure they're right.
Multiply both sides usuinf the fraction
Answer:
10v^2
Step-by-step explanation:
(I'm assuming the 2's are all exponents)
3v^2 - 2v^2 + 9v^2 <- think of it as 3 - 2 + 9 = 10, then add the rest back on
10v^2
