The center of a circle and a point on the circle are given. Write the equation of the circle in standard form.
center: (2,-5), point on the circle: (-4,-5)

Answers

Answer 1

Answer:

25= (x-2)² + (y+4)²

Hope this helps!!!

Answer 2

Answer:

[tex](x-2)^2+(y+5)^2=36[/tex]

Step-by-step explanation:

The standard form of a circle is given by the equation:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Where (h, k) is the center and r is the radius.

We know that the center is (2, -5). So, we can substitute 2 for h and -5 for k. This yields:

[tex](x-(2))^2+(y-(-5))^2=r^2[/tex]

Simplify:

[tex](x-2)^2+(y+5)^2=r^2[/tex]

Now, we need to determine r. We know that a point on the circle is (-4, -5). Thus, we can determine r by substituting -4 for x and -5 for y. This yields:

[tex](-4-2)^2+(-5+5)^2=r^2[/tex]

Evaluate:

[tex](-6)^2+(0)^2=r^2[/tex]

Evaluate:

[tex]36=r^2[/tex]

Hence, the radius squared is 36.

We do not actually need to solve for r, as we will square it anyways.

We will substitute 36 for r squared. Hence, our equation is:

[tex](x-2)^2+(y+5)^2=36[/tex]

The radius will thus be 6 units.

John bought 15 cookies and ate 3 of them. He ate % of the cookies. (Make sure to enter the answer using numbers only. Do not enter special characters such as the percent symbol.)

Answers

He ate 20% of the cookies

Answer:

20%

Step-by-step explanation:

Divide 3 by 15 to get 1/5. If you divide 1 by 5, you will get a decimal answer of 0.2. To convert a decimal to a percent, you must multiply the decimal by 100, which basically means to move the decimal place to the right twice. You will then get the product and final answer of 20%.

A line passes through the point (10,9) and has a slope of 3/2. Write an equation in slope intercept form for this line

Answers

Answer:

The equation of line passing through (10,9) and having slope 3/2 is: [tex]y = \frac{3}{2}x-6[/tex]

Step-by-step explanation:

The slope intercept form of a line is given by:

[tex]y=mx+b[/tex]

We are given

Slope = m = 3/2

Point = (10,9)

Putting the value of the slope in the equation we get

[tex]y = \frac{3}{2}x+b[/tex]

b is the y-intercept. To find the y-intercept we have to put the point through which the line passes in the equation.

Putting (10,9) in the equation

[tex]9 = \frac{3}{2}(10) +b\\9 = 15+b\\b = 9-15\\b = -6[/tex]

Putting b=-6 in the equation

[tex]y = \frac{3}{2}x-6[/tex]

Hence,

The equation of line passing through (10,9) and having slope 3/2 is: [tex]y = \frac{3}{2}x-6[/tex]

Determine what type of number the solutions are and how many exist for the equation 3x^2+7x+5=0

Answers

Answer:

Two complex (imaginary) solutions.

Step-by-step explanation:

To determine the number/type of solutions for a quadratic, we can evaluate its discriminant.

The discriminant formula for a quadratic in standard form is:

[tex]\Delta=b^2-4ac[/tex]

We have:

[tex]3x^2+7x+5[/tex]

Hence, a=3; b=7; and c=5.

Substitute the values into our formula and evaluate. Therefore:

[tex]\Delta=(7)^2-4(3)(5) \\ =49-60\\=-11[/tex]

Hence, the result is a negative value.

If:

The discriminant is negative, there are two, complex (imaginary) roots. The discriminant is 0, there is exactly one real root. The discriminant is positive, there are two, real roots.

Since our discriminant is negative, this means that for our equation, there exists two complex (imaginary) solutions.

Need help ASAP !!!!!!!!!!!!! Which statements describe the graph of f(x) = -1/4x as a transformation of the graph of g(x) = 1/x? Check all that apply.
A- the graph includes a vertical stretch.
B- the graph includes a compression.
C-the graph remains on the same side of the x-axis. D- the graph reflected across the x-axis ?

Answers

Answer:

It's B - The graph includes a compression

and D - The graph is reflected across the x-axis

Step-by-step explanation:

I got those right

B is right because f(ax) if a is greater than 1, then it includes a horizonal compression and 1/4x = f(4x)

D is right because -f(x) reflects across the x-axis. -f(x)= -1/x.

So -f(4x) = -1/4x

\begin{aligned} HD&=\blueE{HP}+DP \\\\ &=\blueE{2}+9 \\\\ &=11 \end{aligned}

HD

 

=HP+DP

=2+9

=11

Using the AAA similarity theorem, the length of segment HD in the diagram given is: 11 units.

What is the AAA Similarity Theorem?

If all corresponding angles of two  triangles are congruent, then, they are similar triangles, based on the AAA similarity theorem.

ΔPOH ~ ΔPID by AAA similarity theorem.

Therefore, their corresponding sides would be proportional. Thus:

PH/PD = PO/PI

Substitute

PH/9 = 6/27

PH = (9 × 6)/27

PH = 2

HD = 2 + 9

HD = 11 units.
