Answer:

c

Step-by-step explanation:

From the definition of a function, an x-value cannot have more than 1 corresponding y-value. Since x = -5 has already been used, it cannot be used again with a different value for y.

PLEASE NEED THIS DONE AS FAST AS POSSIBLE!!!!!!!!!!!!!!!!!<br> IT MUST BE CORRECT

LuckyWell [14K]

Answer:

1)7.288 feet

2)11.6 feet

3)safe

4) 3.7 feet

5) ∅ $= tan^{-1}(1.5) = 56.31 degrees$

6)∅1 $= tan^{-1}(2) = 63.43 degrees$

∅2 $= tan^{-1}(1.2) = 50.19 degrees$

Step-by-step explanation:

1) The door barn is rectangular in shape. The length is 9 feet and The angle between diagonal and side is 39 degrees.

Applying trigonometry,

tan(39) = $\frac{opposite}{adjacent} = \frac{s}{9}$ = 0.809

Thus, s= $(9)(0.809) = 7.288 feet$

2) Applying pythagoras theorm,

$(Diagonal)^{2} = (9)^{2} + (7.288)^{2} =134.115$

Diagonal length (d) = 11.58 feet. Nearest tenth place = 11.6 feet

3) The length of ladder is 14 foot and height from ground is 13.5 feet.

Applying trigonometry,

sin(∅) = $\frac{opposite}{hypotenous} = \frac{13.5}{14}$ = 0.964

∅ = angle of elevation = $sin^{-1}(0.964)$ = 74.57 ≈ 75 degrees.

Thus tractor can climb safely.

4)Applying, pythgoras theorm,

$14^{2} = (13.5)^{2} + x^{2}$

x = $\sqrt{14^{2}-(13.5)^{2}} = 3.708$

Thus, ladder should be placed at distance 3.7 feet

5)Let angle of elevation be ∅.

tan(∅) = $\frac{30}{20} = 1.5$

∅ $= tan^{-1}(1.5) = 56.31 degrees$

6)After moving 5 feet closer to barn, Let angle of elevation for light near barn be ∅1 and for farther one be ∅2.

Thus,

tan(∅1) = $\frac{30}{15} = 2$

∅1 $= tan^{-1}(2) = 63.43 degrees$

tan(∅2) = $\frac{30}{25} = 1.2$

∅2 $= tan^{-1}(1.2) = 50.19 degrees$

What is y and x in simple radical form

vodka [1.7K]

Answer:

Step-by-step explanation:

This is a 30°-60°-90° triangle, so the sides are in the ratio 1:√3:2

The side opposite the 90° angle is 16, so the side opposite the 30° angle is 8, and the side opposite the 60° angle is 8√3.

x = 8√3

y = 8
