Answer:

( About ) 1.77 seconds; Option B

Step-by-step explanation:

We are given the equation h ( t ) = - 16t^2 + 50, so in order to determine the time let us determine the x - intercept for y ⇒ 0;

- 16t^2 + 50 = 0,

- 16t^2 = - 50,

t^2 = 25 / 8,

Thus t ⇒ √ ( 25 / 8 ), and t ⇒ - √ ( 25 / 8 ),

t ⇒ ( 5√2 )/ 4, and - ( 5√2 )/ 4,

But time is represented only by a positive value, thus

t ⇒ ( 5√2 )/ 4 = 1.767766953......., ( About ) 1.77 seconds

Answer; ( About ) 1.77 seconds; Option B

A ladder leans against a 22-feet-tall apple tree. The base of the ladder forms a 42° angle with the ground. Approximately how ta

igomit [66]

(D) 33 feet

Explanation:

Given:

Height of the tree, h = 22 feet

angle, θ = 42°

Length of the ladder, l = ?

We know:

sin θ = Perpendicular / hypotenuse

So,

Sin θ = height of the tree / length of the ladder

$sin 42^0 = \frac{22}{l} \\\\0.67 = \frac{22}{l} \\\\l = 32.84 feet$

l = 32.84 feet ≈ 33 feet

Therefore, the length of the ladder be to reach the top of the apple tree is 33 feet.

Answer:

7.9 ft

Step-by-step explanation:

The hypotenuse is the side opposite of the right angle, hence the hypotenuse for this triangle is 11 ft.

Side $x$ is adjacent to the angle given. So we need adjacent and we have hypotenuse. Which trigonometric ratio relates adjacent and hypotenuse? It is COSINE.

Thus, we can write:

$cos(A)=\frac{adjacent}{hypotenuse}\\cos(44)=\frac{x}{11}$

Cross multiplying, we can solve for $x$ :

$cos(44)=\frac{x}{11}\\x=cos(44)*11\\x=7.91$

Rounding to nearest tenth, we have $x=7.9$ ft.
