An eagle perched 40 ft up in a tree looks down at a 35 degree angle(angle of depression) and spots a vole. How far is the vole f

maria [59]

Answer:

$X=49ft$

Step-by-step explanation:

From the question we are told that:

Height of Eagle $h=40ft$

Angle of depression $\theta=35\textdegree$

Generally the trigonometry equation for diagonal X is mathematically given by

$Cos\theta \textdegree=\frac{Adjacent}{Hypotenuse} }$

$Cos\theta \textdegree=\frac{h}{X} }$

$X=\frac{40}{Cos 35 } }$

$X=48.83ft$

$X=49ft$

What is the elimination to this solution i think its b

Blababa [14]

EXPLANATION:

To get the solution of the simultaneous equation, using the elimination method:

We will have the following steps:

Step 1:

Write the two equations:

$\begin{gathered} y=-\frac{1}{2}x+3 \\ y=-\frac{7}{2}x-3 \end{gathered}$

Step2: Subtract the two equations:

$\begin{gathered} y-y=-\frac{1}{2}x-(-\frac{7}{2}x)+3-(-3) \\ 0=-\frac{1}{2}x+\frac{7}{2}x+6 \\ \end{gathered}$

Step 3: Simplify the expression

$\begin{gathered} 0=3x+6 \\ 3x=-6 \\ x=-\frac{6}{3} \\ x=-2 \end{gathered}$

Step 4: Substitute x=-2 into the formula:

$\begin{gathered} y=-\frac{1}{2}x+3 \\ y=-\frac{1}{2}\times-2+3 \\ y=1+3 \\ y=4 \end{gathered}$

Therefore, the answer is

$(-2,4)$

Thus,

Option B is correct

Answer:

Question #3: Answer = 31

Step-by-step explanation

• Plug in 3 for x

• Plug in -4 for y

| -3(3)² + 2(-4) | -(3)(-4)

From here, simplify. Don't forget to use PEMDAS!

| -27 +8 | + 12

| -19 | + 12

19 + 12

Use this same method to solve for Question #2!
