Derive standard form of an equation of a circle with center C(5,2) and radius r=4, using the Pythagorean theorem.

Answers

Answer:

(x-2)^2 + (y - 5)^2 = 16

Step-by-step explanation:

Given the standard form of an equation of a circle

(x-h)^2+(y-k)^2=r^2

If (h, k) = (5,2) and r = 4

Substitute

(x-2)^2 + (y - 5)^2 = 4^2

(x-2)^2 + (y - 5)^2 = 16

Hence the required equation is (x-2)^2 + (y - 5)^2 = 16

Angel has xx dimes and yy nickels. He has at most 13 coins worth no less than $0.95 combined. Solve this system of inequalities graphically and determine one possible solution.

Answers

Answer:

a possible solution is (10,1)

Step-by-step explanation:

Here, we want to solve the given inequality and determine one possible solution

From the question, we have it that;

x + y ≤ 13

Mathematically, we have it that 1 dime is worth $0.1

A nickel is worth $0.05

0.1x + 0.05y ≥ 0.95

please check the attachment for the graph of both equations

The point of intersection represents the solution.

A student has 6 nickel 14 dimes and 8 quarter.what is the ratios of the total number of coins to the number of nickels ? In simplest form

Answers

Given:

A student has 6 nickel 14 dimes and 8 quarter.

To find:

The ratio of the total number of coins to the number of nickels.

Solution:

We have,

Number of nickels = 6

Number of dimes = 14

Number of quarter = 8

Total number of coins = 6+14+8

                                     = 28

Now, the ratio of the total number of coins to the number of nickels is

[tex]Ratio=\dfrac{\text{Total number of coins}}{\text{Number of nickels}}[/tex]

[tex]Ratio=\dfrac{28}{6}[/tex]

[tex]Ratio=\dfrac{14}{3}[/tex]

[tex]Ratio=14:3[/tex]

Therefore, the  ratio of the total number of coins to the number of nickels is 14:3.

1. Gloria says the two expressions - (12x + 24) - 9x and -6(x + 1) are equivalent. Is she correc Explain how you know.​

Answers

Answer:

No they aren't equivalent

Step-by-step explanation:

Let's take each expression

the first one is

- (12x+24) - 9x = -12x -24 -9x = -21x -24 = -3 (7x +8)

the second expression

-6 (x+1) = -6x-6

So they aren't equivalent

A pentagon is transformed according to the R 180 degrees. Which is another way to state the transformation?

Answers

Answer:

(x, y) → (–x, –y)

Step-by-step explanation:

Given

[tex]R_0, 180^{\circ}[/tex]

Required

Another way to write the above transformation

The above transformation means 180 degrees clockwise rotation.

When a coordinate point (x,y) undergoes this type of transformation, the new coordinate point becomes (-x,-y).

Hence, another way to write [tex]R_0, 180^{\circ}[/tex] is (x, y) → (–x, –y)

3² • 9³ = [ ]
solve ​

Answers

Answer:

3⁸ or 6561

Step-by-step explanation:

First, let's look at PEMDAS - Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

There are no parentheses, so let's solve the exponents.

3² • 9³

3² = 9

9³ = 729

Your expression is:

9 • 729

Now let's multiply.

= 6561

This number can also be expressed with exponents.

Since 9 = 3², 9³ = 3²⁽³⁾

Now your expression is:

3² • 3²⁽³⁾

First, solve the exponents by multiplying.

3² • 3⁶

When you multiply two expressions with exponents that have the same base (3), you add the exponents.

3² • 3⁶ = 3⁽²⁺⁶⁾ = 3⁸

3⁸ also equals  6561.

Your answer is 3⁸ or 6561.

Hope this helps!

Step-by-step explanation:

Given

Points: (0,3) and (-4,-1)

Formula

x = 0 to find the y intercept

m = (y2 - y1)/(x2 - x1)

Solution

y2 = 3

y1 = - 1

x2 = 0

x1 = - 4

m = (3 - -1)/(0 - - 4)

m = 4/4

m = 1

You have y = mx + b so m = 1

the general equation becomes y = x + b

Use point (0,-4)

y = x + b

- 4 = 0 + b

b = - 4

y = x - 4
