<h2>Area</h2>

Find the Area of shaded figure.

<h3>Solution:</h3>

Problem 13.

  • A = π r²
  • AB= π (2inch)²
  • A = 2 x 2
  • A = 4inch π
  • As = π(4inch)
  • A = 4 x 4
  • A = 16inch
  • A = 4inch x 3.14 = 12.56
  • A = 16inch x 3.14 = 50.24
  • A = 50.24 - 12.56
  • A = 37.68units²

Problem 14.

  • A = Radius ,13²
  • A = (3.14)
  • A = 13 x 13
  • A = 169π
  • A = 3/8 x 169 π
  • A = 3 × 169
  • A = 507
  • A = 507 ÷ 8
  • A = 63.375π
  • A = 63.375 x 3.14
  • A = 198.9975 inch²

Problem 15.

  • A = π r²
  • A = 10cm
  • A = 10cm x 10cm
  • A = 100cm²
  • A = 100 cm² - 78.5
  • A = 21.5cm²

An advertising blimp hovers over a stadium at an altitude of 125 m. The pilot sights a tennis court at and 8° angle of depressio
tatuchka [14]

Answer:

Hence the ground distance is about 889m between stadium and Tennis court.

Step-by-step explanation:

Given:

A pilot at height of 125 m(flying the advertising blimp)

angle of depression=8 degrees.

To find :

The ground distance  stadium and tennis court.

Solution :

Using Trigonometric Function we can solve it ,

(Refer the attachment for fig)

Considering above data we get a triangle(ABC)

with point A represent pilot position and C court position and B as stadium.

The height AB=125 m

angle of depression= 8 degrees.

Using

<em>tan∅ =AB/BC</em>

tan(8)=125/BC

BC=125/tan(8)

=125/0.14054

=889.2

=889 m

Hence the ground distance is about 889m between stadium and Tennis court.

Write the quadratic equation in general form and then choose the value of "b."
eduard
The answer is b. 11. 

You can find this by multiplying the two parenthesis together. In order to do this, you can use a multiplying process known as FOIL (First, Outer, Inner, Last), where you multiply parts of the parenthesis in this order to make sure you do so properly. 

First Numbers:
2x * x = 2x^2

Outer Numbers: 
2x * 6 = 12x

Inner Numbers: 
-1 * x = -1x

Last Numbers: 
-1*6 = -6

Now place them all in that order and simplify. 
2x^2 + 12x - x - 6 ---> simplify x terms
2x^2 + 11x - 6

Since the middle term (the one with the x value) has a coefficient of 11, that gives us a b value of 11.

Which function is represented by the graph?
solong [7]

Answer:

f(x) = |x + 1| – 3

Step-by-step explanation:

The given graph is a transformed absolute value function.

The parent function is

g(x) =  |x|

The graph is obtained by shifting, g(x) from the origin (0,0) to (-1,-3).

The transformed function is of the form:

f(x) =  |x - h|  + k

Where (h,k) is the vertex.

We substitute h=-1 and k=-3 to get:

f(x) =  |x -  - 1|  +  - 3

When we simplify we get:

f(x) =  |x  + 1|  - 3
