$( - 3x - 6) - (2x + 3) =$

$- 3x - 6 - 2x - 3 =$

$- 3x - 2x - 6 - 3 =$

Collect like terms

$- (3 + 2)x - 9 =$

$- 5x - 9$

What is the error in this problem

Anastaziya [24]

Answer:

The angle of elevation is not properly represented

Step-by-step explanation:

Given

The question in the attachment;

Required

Determine the error

<em>See attachment for proper representation of the angle of elevation;</em>

<em>Solving further (From the Attachment)</em>

$Tan22 = \frac{x}{3000}$

Multiply both sides by 3000

$x = 3000 * tan22$

$x = 3000 * 0.4040$

$x = 1212$

<em>The cliff is about 1212 feet high</em>

Recall the equation for a circle with center (h,k) and radius r. At what point in the first quadrant does the line with equation

IgorC [24]

Answer:

At intersection

x=2.68

y=5.34

Step-by-step explanation:

Equation of circle with center (h,k) and radius r is

$(x-h)^{2}+(y-k)^{2}=r^2\\\\With\,\, center\,\,(0,4)\,\, and\,\, r=3\\\\(x-0)^{2}+(y-4)^{2}=3^2\\\\x^2+(y-4)^{2}=9---(1)\\\\Equation\,\,of intersecting\,\,line\\y=0.5x+4---(2)$

To find point of intersection:

From (2)

$x=\frac{y-4}{0.5}=2(y-4)\\\\x^2=4(y-4)^{2}\\\\Put\,\,in\,\,(1)\\\\4(y-4)^{2}+(y-4)^{2}=9\\\\5(y-4)^{2}=9\\\\y-4=\frac{3}{\sqrt{5}}\\\\y=1.34+4\\\\y=5.34\\\\x=2(5.34-4)\\\\x=2(0.34)\\\\x=2.68$
