PLZ HELP ASAP CIRCLES

Mathematics
1 answer:
DENIUS [597]3 years ago
5 0
Because the AC line is tangent to the circle then we have to:
 angle C = 90 degrees.
 Then, the sum of the angles of a triangle is 180 degrees.
 Therefore, we have:
 23 + 90 + O = 180
 Clearing the angle O we have:
 O = 180-90-23
 O = 67 degrees
 Answer:
 
the angle O is given by:
 
O = 67 degrees

Answer:

Part A) The percentage increase was 6.1\%

Part B) Michael is financially better off this year than last year

Step-by-step explanation:

Part A)

we know that

Using proportion

Let

x-----> the percentage increase

\frac{100\%}{33,000}=\frac{x\%}{35,000-33,000}\\ \\x=2,000*100\%/33,000\\ \\x=6.1\%

Part B) Compare the percentage increase with the inflation

6.1\%>5\%

The percentage increase is greater than the inflation

therefore

Michael is financially better off this year than last year

A circle representing a pool is graphed with a center at the origin. Grant enters the pool at point A and swims over to a friend
MA_775_DIABLO [31]

From the diagram above you can see that points A and B have coordinates (8,0) and (-4,6), respectively.

The equation of the line passing through the pointa A and B is:

y-y_A=\dfrac{y_B-y_A}{x_B-x_A}(x-x_A).

Then

y-0=\dfrac{6-0}{-4-8}(x-8),\\ \\y=-\dfrac{6}{12}(x-8),\\ \\y=-\dfrac{1}{2}(x-8),\\ \\y=-\dfrac{1}{2}x+4.

Answer: y=4-\dfrac{1}{2}x.

four plastic bottles, each with a radius of 2 inches, are packed into a cardboard box. The glasses touch each other and the side
shepuryov [24]

The area of a 2D form is the amount of space within its perimeter. The area of the bottom of the box is 64 square inches.

<h3>What is an area?</h3>

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or other quadrilateral, multiply its length by its width.

Given the radius of the base of the plastic bottle is 2 inches, and there are four bottles arranged as shown below, therefore, the area of the bottom of the box is,

\rm \text{Area of the bottom of the box} = 8 \times 8 = 64\ in^2

Hence, the area of the bottom of the box is 64 square inches.

What is the period of the function F(x) = -4sec (1/2 x)
serg [7]

Answer:

A) 4π

Step-by-step explanation:

The period of a secant function, f(x)=a*sec(bx+c)+d, is defined as 2π/|b| where b is the distance of the period. Since we know b=1/2 given by the function, then the period is 2π/|1/2|=2π/(1/2)=2π(2/1)=4π.

When you write terms in denominator on numerator, sign of indices changes.
\frac{18x^{-2}y^{2}}{2x^{2} y} =  \frac{(18x^{-2}y^{2})*(x^{-2}y^{-1})}{2} &#10; = 9(x^{-4} y^{1})
