Answer:

Perimeter of the rectangle is 29x + 1 feet

Step-by-step explanation:

Length of the rectangle = 9.5x + 10 feet

Width of the rectangle = 5x - 9.5 feet

perimeter of rectangle = 2 ( length + width )

perimeter = 2 { (9.5x + 10) + (5x-9.5) }

perimeter = 2 ( 9.5x + 5x + 10 - 9.5 )

perimeter = 2 (14.5x + 0.5)

perimeter =29x + 1 feet

The angle of depression from the top of a flag pole to a point on the ground is 30°. If the point on the ground is 75 feet from
Cerrena [4.2K]

Answer:

Height of flag pole to the nearest foot is 43 feet

Step-by-step explanation:

In the diagram we have flag pole AB and C is the point on the ground.

It is given that angle of depression is 30°

and the distance of the point C from the base B is 75 feet

so we have

BC= 75 feet  

∠C = 30°

AB= h feet

now in right ΔABC

tan C = \frac{opposite \ side }{base} \\tan C=\frac{AB}{BC}

now we plug AB= h , ∠C= 30° and BC =75

tan 30= \frac{h}{75}

75 tan30 = h            ( multiply both sides by 75)

h= 75 tan 30 =75 (0.5773)\\ h= 43.3 feet\\

Height of flag pole to the nearest foot is

h= 43 feet

What is the value of x ​
GarryVolchara [31]
<h2><u>We can solve it using trigonometric values.</u></h2>

<h3>So , <u> </u><u>sin</u><u> </u><u>θ</u><u> </u> = ( Perpendicular / Hypotenuese )</h3>

<h2><u>Given</u><u> </u></h2>

Perpendicular = x

Hypotenuese = 30

{ \sf{sin \:  \: 45 {}^{ \degree}   = \dfrac{1}{ \sqrt{2}  }  =  \dfrac{x}{ 30} }}

{ \sf{x =  \dfrac{30}{ \sqrt{2} } }}

<h2>∴ x ( Perpendicular)= 15√2 <u>Ans</u><u>.</u></h2>

Suppose that a population parameter is 0.1, and many samples are taken from the population. If the size of each sample is 90, wh
mr Goodwill [35]
I think the answer is Letter C - 0.032.

Given: p - 0.1; n - 90
Required: standard deviation of the sample proportion
Solution: To get the standard deviation of the sample proportion, we will use this formula - std = √p (1 - p) / n Replace the variables with the given values, then simplify.
   std = √0.1 (1 - 0.1) / 90
   std = √0.09 / 90
   std = √0.001
   std = 0.032
