A person of height 1.6m up to the eye level is standing at a point 2m away from the bank of the river and found an angle of elev

natima [27]

Step-by-step explanation:

tan30° = Height of person / (Distance away from river bank + river's width) = 1/√3.

Therefore 1.6m / (2m + x) = 1/√3

By cross multiplication, 1.6√3 = 2 + x.

Hence, x ≈ 0.77m.

37-(-3)squared+30\(-3)x2

vampirchik [111]

Simplify:
37 - (-3)^2 + 30/(-3)x^2
= 37 + - 9 + - 10x^2

Combine like terms:
= 37 + - 9 + - 10x^2
= ( - 10x^2) + (37 + - 90
= - 10X^2 + 28
Answer: - 10x^2 + 28

To Factor:
37 - (- 3)^2 + 30/- 3x^2

- 10x^2 + 28
- 2(5x^2 - 14)

Answer: - 2(5x^2 - 14)

I simplify, and factor, because, you didn't really specify what you wanted help on with this equation. - Thanks -

Hope that helps!!!!

Choose the equation for the relationship shown in the graph.

uysha [10]

Answer:

B) y = x - 50

Step-by-step explanation:

It is B because the graph's y-intercept lies on the point (0, -50), hence the equation, y = x - 50. In addition, you can verify that B is the correct answer because the slope of the graph is positive, and so the x-value also must be positive.
