What is the equation of a circle with the center (2,3) that passes through the point (5,3)
The given center and point on the circle of (2, 3), and (5, 3), respectively
gives the equation of the circle as; [tex]\underline{(x - 2)^2 + (y - 3)^2 = 3^2}[/tex].
How can the equation of the circle be found?The general form of the equation of the circle is presented as follows;
(x - h)² + (y - k)² = r²
Where;
(h, k) = The center of the circle
r = The radius of the circle
Which gives;
(h, k) = (2, 3)
h = 2
k = 3
r = √((5 - 2)² + (3 - 3)²) = 3
The equation of the circle is therefore;
[tex]\underline{(x - 2)^2 + (y - 3)^2 = 3^2}[/tex]Learn more about the equation of a circle here:

Find the slope of the line that contains the I
point (4, -9) and has a y intercept of 2.
Answer:
-11/4
Step-by-step explanation:
The y intercept has the coordinates of (0,2)
We have two points (0,2) and (4,-9) so we can find the slope using
m= (y2-y1)/(x2-x1)
= ( -9-2)/(4-0)
= -11/4
Answer:
-11/4
Step-by-step explanation:
y = mx + c
Point (x,y)
intercept c
slope m
-9 = m(4) + 2
-9 = 4m + 2
make m the subject of the formula
4m = -9-2
4m = -11
divide both sides by 4
m = -11/4

Step-by-step explanation:
x = 24
Quadrilateral:
We have 94° + 41° + a + b.
Using 111°, we can do 180 - 111 and get 69°.
Now, we have 94° + 41° + 69° + b.
A quadrilateral's angles will equal 360°.
94 + 41 + 69 + b = 360°
204 + b = 360°
b = 156
Triangle:
Now, we can do 180 - 156 to find x.
x = 24

Dylan has 0.5 liters of water. He needs to find out how many milliliters of water he has so he can complete his science experiment. How many milliliters (mL) of water does Dylan have
Answer:
500 milliliters
Step-by-step explanation:
Dylan has 0.5 liters of water. He needs to find out how many milliliters of water he has so he can complete his science experiment. How many milliliters (mL) of water does Dylan have
1 liter of water = 1000 milliliters of water
0.5 liters of water = x
Cross Multiply
x = 0.5 × 1000 milliliters of water
x = 500 milliliters of water
Therefore, Dylan has 500 milliliters of water

The total value of the coins is 3.88. Anita has 4 more nickels than pennies and 2 more than 4 times the number of quarters than pennies. How many of which coins does she have?
Answer:
See explanations below
Step-by-step explanation:
Let the amount of nickel be x
Let the amount of pennies be y
Let the amount of quarters be z
If the the total value of the coins is 3.88, then;
x+y+z = 3.88 .... 1
If Anita has 4 more nickels than pennies, then;
x = y + 4 ... 2
If she has 2 more than 4 times the number of quarters than pennies, then;
y = 2 + 4z
4z = y-2
z = (y-2)/4 ...3
Substitute 2 and 3 into 1
y+4+y+(y-2)/4 = 3.88
4y+16+4y + y-2 = 15.52
9y + 14 = 15.52
9y = 15.52 - 14
9y = 1.52
y = 1.52/9
y = 0.17
Since x = y + 4
x = 0.17+4
x = 4.17
z = y-2/4
z = 0.17-2/4
z = -1.83/4
z = - 0.46

HELP ASAP. solve for x
Answer:
x = 25
Step-by-step explanation:
The triangle is isosceles, therefore, the base angles are the same
62 + 2x + 9 + 2x + 9 = 180
62 + 4x + 18 = 180
4x = 180 - 62 - 18
4x = 100
x = 100/4
x = 25
In OPQ, the measure of Q=90°, OP = 96 feet, and PQ = 23 feet. Find the measure
of 20 to the nearest degree.
Answer:
[tex]O = 14^\circ[/tex]
Step-by-step explanation:
Given
[tex]\angle Q = 90[/tex]
[tex]OP = 96[/tex]
[tex]PQ = 23[/tex]
Required
Find [tex]\angle O[/tex] to the nearest degree
To calculate O, we make use of:
[tex]sin(O) = \frac{PQ}{PO}[/tex] --- See attachment for triangle
[tex]sin(O) = \frac{23}{96}[/tex]
[tex]sin(O) = 0.2396[/tex]
Take arcsin of both sides
[tex]O = sin^{-1}(0.2396)[/tex]
[tex]O = 14^\circ[/tex] -- approximated
