Write the equation in standard form for the circle with center (-7,5) and radius 8

Answers

Answer 1

Answer:

64 = (x+7)^2 + (y-5)^2

Step-by-step explanation:

Equation of a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So the equation is: 64 = (x+7)^2 + (y-5)^2

Answer:

[tex]\csc\theta=\dfrac{1}{a}[/tex]

Step-by-step explanation:

Given that,

[tex]\sin\theta=a[/tex]

We need to find the value of [tex]\csc\theta[/tex].

We know that, the relation is given as follows :

[tex]\sin\theta=\dfrac{1}{\csc\theta}\\\\\csc\theta=\dfrac{1}{\sin \theta}[/tex]

Put [tex]\sin\theta=a[/tex]

So,

[tex]\csc\theta=\dfrac{1}{a}[/tex]

So, the answer is equal to [tex]\dfrac{1}{a}[/tex].

Answers

Answer:

1) A) 25%

2) B) 16%

3) A) 93%

Step-by-step explanation:

0.25 = 25%

More than 3 means, 4 and 5

0.12 + 0.04 = 0.16 = 16%

x ≥ 1

So that means 1+ days (everything except 0)

0.25 + 0.18 + 0.34 + 0.12 + 0.04

0.93 = 93%

What is the value of x in the following equation?
7 = 2x^2 - x - 8 + x - 3

Answers

Answer:3,-3

Step-by-step explanation:

begin by simplifing the expression. So, the 2 x's will cancel out in the expression. you should have 7=2x^2-11. Then Subtract the 7 from both sides so you cna use the quadratic formula. This gives you 2x^2-18=0. Using the formula {-b+/sqrt(b^2-4ac)}/2a this gives us {-0+/sqrt(0^2-4*2*-18)}/2*2 this simplifies to 0+/- 12 all over 4. +12/4=3 and -12/4=-3.

Which ordered pair is a solution for 3x + 4y < 12?

Answers

Answer:

D, (1,2)

Step-by-step explanation:

It all comes down to substitution. In this case the coefficient of x is 3 and the coefficient of y is 4. The format of these coordinates being (x,y).

1. Plug in your x value (1 in this circumstance) and solve:

3(1) + 4y < 12

3 + 4y < 12

2. Plug in your y value (2 in this circumstance) and solve:

3 + 4(2) < 12

3 + 8 < 12

3. Solve

3 + 8 = 11

11 < 12

Estimate the perimeter and the area of the shaded figure

Show how u got it please.

Answers

Answer:

8(1 +√2)

Step-by-step explanation:

The perimeter is the sum of the sides of the figure

Taking 1 square box as 1 unit

Get the slant side using the pythagoras theorem;

l² = 2² + 2²

l² = 4 + 4

l² = 8

l =√8

Perimeter = 4(√8) + 4 + 4

Perimeter = 8 + 4√8

Perimeter = 8 + 4*2√2

Perimeter = 8 + 8√2

Perimeter = 8(1 +√2)

hence the perimeter of the shape is 8(1 +√2)

Three Methods for Choosing JudgesAt the federal level, judges are nominated by the President and then those nominees have to be approved by the Senate. The U.S. Constitution does not specify how states can choose their judges so different states use different methods. The three most common methods used by states are listed below:Method 1: Direct elections - Candidates raise money and campaign to be a judge. The voters then elect one of the candidates.Method 2: Appointment - In this method, state judges are appointed by the Governor. There is often no legislative approval required. A couple of states have the state legislature appoint judges, but usually it is the Governor.Method 3: The Missouri Plan - This is a compromise between methods 1 and 2. In the Missouri Plan, the governor appoints judges, but the governor must make each appointment from a list of three candidates recommended by a judicial nominating commission. The commission is made up of a sitting judge, several legal experts, and some private citizens. Each judge named by the governor serves until the next election. The judge's name then appears on the ballot without opposition. The voters decide, in a yes-no vote, whether or not that judge should be kept in office. Should the voters reject a sitting judge, the process begins again.Read the information above about the three methods most commonly used to select judges at the state level. Pick the method that you believe is the best. Write a paragraph persuading your fellow Ohioans that Ohio should start using this method. If you agree with how Ohio already chooses its judges, then persuade a different state to use our current method. Your essay needs to provide three (3) arguments supporting your method of choice, and you need to back these arguments up with supporting details. For example, you could use constitutional principles to back up your arguments.plz help Ultraviolet light from the Sun can Hi here equation everybody please help thanks Diana has just been diagnosed with "pre-diabetes," and her doctor has instructed her to watch her intake of sugar.
