(0,-9);r=9 find the equation for the circle

Answers

Answer 1

Answer: x^2 + y^2 + 18y + 81 = 0

Step-by-step explanation:

The equation of a circle with center at the point (0, -9) and radius 9 is given by the following equation:

(x - 0)^2 + (y + 9)^2 = 9^2

This can be simplified to the following:

x^2 + y^2 + 18y + 81 = 0

This is the equation of a circle with center at (0, -9) and radius 9.

Answer:

Step-by-step explanation:

Just add the three sides    P = side1 + side2 + side3

Don't let the 'x' terms confuse you, they are just numbers times 'x'

P = 3x+1/2  + 2x+1/4  +  x+1/2

For each triangle find the value of x

Answers

Answer:

x = 20

Step-by-step explanation:

The sum of the angles in a triangle is 180. A right triangle has one angle of 90. Thus, the sum of the other two angles will be 90. So, 90+31 = 121 and 180-121 = 59. (3x-1) = 59. Solve for x. This would mean that x would be 20. 3*20 = 60 and 60-1 = 59. All the angles add together would get 180: 59+90+31.

A box contains four equal-sized cards labeled 1 , 3, 5, and 7. Tim will select one card from the box. What is the probability that Tim will select a card labeled 3?

Answers

Answer: 1/4

Step-by-step explanation:

Since the box box contains four equal-sized cards labeled 1 , 3, 5, and 7. The probability of selecting any number out of the four numbers will be 1/4 if they are selected once.

If Tim selects one card from the box, the probability that Tim will select a card labeled 3 will be: = 1/4

This is because 3 only occurs once and there are 4 numbers in total.

Answers

Answer:

x = 312

Step-by-step explanation:

We know that ∠ABD and ∠CBD are supplementary, meaning their measures add up to 180°. We can use this knowledge to put both measures into an equation.

[tex](0.18x+56) + (0.07x+46)= 180[/tex]

Simplify.

[tex]0.18x+56 + 0.07x+46= 180[/tex]

Simplify.

[tex]0.25x + 102 = 180[/tex]

Subtract 102.

[tex]0.25x = 180 - 102[/tex]

Simplify.

[tex]0.25x = 78[/tex]

Divide by 0.25

[tex]x = \frac{78}{0.25}[/tex]

Simplify.

[tex]x = 312[/tex]

A 23.7-foot tall flagpole casts a 42-foot shadow. What is the angle that the sun hits the flagpole? Express your answer in DMS

Answers

Answer:

60.6°

Step-by-step explanation:

Using trigonometry :

Opposite = Height of shadow = 42 feets

Adjacent = height of flagpole = 23.7 feets

Tan θ = opposite / Adjacent

Tan θ = height of shadow / height of flagpole

Tan θ = 42 / 23.7

Tan θ = 1.7721518

θ = tan^-1(1.7721518)

θ = 60.56

θ = 60.6°
