Which of the following is an equation of a circle in
the xy-plane with center (0, 4) and passes through (4/3,5)
Answer:
[tex]x^2 + (y - 4)^2 = \dfrac{25}{9}[/tex]
Step-by-step explanation:
The equation of a circle with center at (h, k) and radius r is
[tex] (x - h)^2 + (y - k)^2 = r^2 [/tex]
You have center (0, 4).
We get:
[tex] (x - 0)^2 + (y - 4)^2 = r^2 [/tex]
[tex] x^2 + (y - 4)^2 = r^2 [/tex]
To find the radius, we use the distance formula to find the distance from the center of the circle to the given point on the circle.
[tex] r = d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
[tex] r = \sqrt{(\dfrac{4}{3} - 0)^2 + (5 - 4)^2} [/tex]
[tex] r = \sqrt{(\dfrac{4}{3})^2 + 1^2} [/tex]
[tex] r = \sqrt{\dfrac{16}{9} + \dfrac{9}{9}} [/tex]
[tex] r = \sqrt{\dfrac{25}{9}} [/tex]
We need r^2 in the equation of the circle, so
[tex] r^2 = \dfrac{25}{9} [/tex]
The equation of the circle is
[tex]x^2 + (y - 4)^2 = \dfrac{25}{9}[/tex]

Answer:
22.5
Step-by-step explanation:
Since 13.5 is 60% of something, the opposite operation would be to divide 13.5 by 60% (or 0.6). You can check this by finding 60% of 22.5:
13.5 / 0.6 = 22.5
22.5 x 0.6 = 13.5
Answer:
In the problem, 60% of 22.5 is 13.5.
Step-by-step explanation:
The first thing we have to do is know what the problem is asking us to find. In the problem, we are asked to find the number that 13.5 is 60% of. In order to find this number, we have to divide. We are going to divide 13.5 by 60%. 60% can be turned into decimal form which is 0.6.
13.5 ÷ 0.6 = 22.5
So, the number that 13.5 is 60% of is 22.5.

Which of the following sets of ordered pairs represents a function?
Answer: {(-8, -14), (-7,-12), (-6,-10), (-5,-8)}
Step-by-step explanation: A function is a relation in which each x-coordinate corresponds to exactly one y-coordinate.
In the relations show here, notice that the first set
of ordered pairs is the only set where each x-coordinate
appears once with a different y-coordinate.
In the other ordered pairs, there is an x-coordinate that appears more
than once and it corresponds to a different y-coordinate.
For example, in the second relation,
the x-coordinate -9 appears twice.
In one case, -9 corresponds to -12 and
in the other case, it corresponds to -8.
So, this is not a function.

PLEASE I NEED HELPP !!o
The figure below shows a quadrilateral ABCD. Sides AB and DC are equal and parallel
A student wrote the following sentences to prove that quadrilateral ABCD is a parallelogram
Side AB is parallel to side DC, so the alternate interior angles, angle ABD and angle CDB, are congruent Side AB is equal to side DC, and DB is the side common to triangles ABD and CDB. Therefore, the triangles ABD and
CDB are congruent by SAS postulate. By CPCTC, angles DBC and BDA are congruent and sides AD and BC are congruent. Angle DBC and angle BDA form a pair of vertical angles that are congruent. Therefore, AD is
parallel and equal to BC Quadrilateral ABCD is a parallelogram because its opposite sides are equal and parallel
Which statement best describes a flaw in the students proof?
O Triangles ABD and BCD are congruent by the SSS postulate instead of the SAS postulate.
Triangles ABD and BCD are congruent by the AAS postulate instead of the SAS postulate.
O Angle DBC and angle BDA form a pair of corresponding angles, not a pair of vertical angles
O Angle DBC and angle BDA form a pair of alternate interior angles that are congruent, not a pair of vertical angles
Answer:
I believe that the answer is Angle DBC and angle BDA form a pair of alternate interior angles that are congruent, not a pair of vertical angles.

Please help me! Ill give brainliest! The incorrect work of a student to solve an equation 2(y + 6) = 4y is shown below: Step 1: 2(y + 6) = 4y Step 2: 2y + 8 = 4y Step 3: 2y = 8 Step 4: y = 4 Which of the following explains how to correct Step 2 and shows the correct value of y? (5 points) 2 should be distributed as 2y + 12; y = 6 2 should be distributed as 2y + 12; y = 3 The equation should be y + 6 = 4y after division by 2; y = 2 The equation should be y + 6 = 4y after division by 2; y = 1
2 should be distributed as 2y + 12; y = 6
Step-by-step explanation:
The equation is...
[tex]2(y+6)=4y[/tex]
First, we need to distribute the 2 to the numbers in the parentheses. We will multiply them both by 2.
[tex]2y+12=4y[/tex]
Now we can subtract 2y from both sides. On the left it will cancel and on the right we will be left with 2y.
[tex]12=2y[/tex]
Now we can just divide and...
y = 6

What is the y-intercept of a line that has a slope of –3 and passes through point (–5, 4)? –17 , –11 , 7 , 19
Answer:
-11
Step-by-step explanation:
There is enough information to put the equation in point slope form.
[tex]y-y_1=m(x-x_1)[/tex]
We are given the point of (-5,4) and the slope of -3.
[tex]y-y_1=m(x-x_1)\rightarrow \boxed{y-4=-3(x+5)}[/tex]
Now, we can take the point slope equation and convert it into slope intercept form.
[tex]y-4=-3(x+5)\\\\\left \{ {{-3*x=-3x} \atop {-3*5=-15}} \right.\\\\ y-4=-3x-15\\\\y-4+4=-3x-15+4\\\\\boxed{y=-3x-11}[/tex]
The y-intercept should be -11.

The sum of two numbers is -12. The difference between the same two numbers is 8. What is the product of the two numbers? ( with explanation )
Answer:
x=-2
y=-10
Step-by-step explanation:
x+y=-12
x-y=8
x=y+8
(y+8)+y=-12
2y+8=-12
2y=-20
y=-10
x+10=8
x=-2
Answer:
[tex]x = - 2 \\ y = - 10[/tex]
Step-by-step explanation:
[tex]x + y = - 12 \\ x - y = 8[/tex]
[tex]x + y + (x - y) = - 12 + 8 \\ x + y + x - y = - 4 \\ 2x = - 4 \\ \frac{2x}{2} = \frac{ - 4}{2} \\ x = - 2[/tex]
[tex]x + y = - 12 \\ - 2 + y = - 12 \\ y = - 12 + 2 \\ y = - 10[/tex]
Find the equation of the line through point (-5,5) and perpendicular to y = 5/9x - 4
Answer:
[tex]9x+5y=-20[/tex]
Step-by-step explanation:
[tex]y = \frac{5}{9} x - 4[/tex]
compare with that y=mx+c
where m=slope .
So after comparing we get m=[tex]\frac{5}{9}[/tex]
As the lines are perpendicular
[tex]m1*m2=\ -1[/tex]
[tex]m2 \ =\ \frac{-1}{m1}[/tex]
therefore m2=[tex]\frac{-9}{5}[/tex]
Now from the equation
[tex]y - b = m(x - a )[/tex] this equation passing to the point (-5,5) with m=[tex]\frac{-9}{5}[/tex]
[tex]y-5=\frac{-9}{5} (x+5)\\5y-25=-9x\ -45\\9x+5y=-20[/tex]
Therefore equation is
[tex]9x+5y=-20[/tex]

168 inches divided by 12 inches per feet equals 14 feet.
Simplify all radicals as far as you can.
9x2 + 12x +4= 0
Note that 9x^2 + 12x +4= 0 has the form of a special product:
(a + b)^2 = a^2 + 2ab + b^2
and so our 9x^2 + 12x +4= 0 factors into (3x + 2)(3x + 2) = (3x + 2)^2
A group of tourists can be sorted into tour boats in groups of 4 or in groups of 6. In either case, there are no empty seats. Find the number of tourists if there are more than 25 and fewer than 45.
Answer: there are 36 tourists.
Step-by-step explanation:
Ok, we have two integer numbers:
T, the number of tourists and S, the number of seats.
Such that, if we divide the tourists into groups of 4 and in groups of 6, we end with no empty seats.
Knowing that the number S must be an integer, and when we divide T into groups of 4 and 6 we end with no empty seats, this means that T can be divided by 4 and by 6.
This means that T is a common multiple of 4 and 6
Now, we also know that 25 < T < 45.
Then let's see which ones are the multiples of 4 between 25 and 45.
4*7 = 28
4*8 = 32
4*9 = 36
4*10 = 40
4*11 = 44.
Now, the multiples of 6 in that range are:
6*5 = 30
6*6 = 36
6*7 = 42.
You can see that 36 is a common multiple, other way to see it is:
4*9 = (2*2)*(3*3) = 2*2*3*3 = (2*3)*(2*3) = 6*6
So the numer of tourist must be 36.

On a coordinate plane, triangle R S T has points (negative 3, 2), (3, 2), and (negative 1, 1). An altitude is drawn from point T to point U at (negative 1, 2).
What is the area of triangle RST?
6 square units
9 square units
12 square units
18 square units
Answer:
The answer is
Step-by-step explanation:
B. 9 square units
The area of the triangle RST is 3 square units if the triangle RST has points (-3, 2), (3, 2), and (-1, 1). An altitude is drawn from point T to point U at (-1, 2).
What is the triangle?The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have:
Triangle RST has points (-3, 2), (3, 2), and (-1, 1).
We are assuming the coordinate for point R is (-3, 2)
S(3, 2)
T(-1, 1)
An altitude is drawn from point T to point U at (-1, 2).
From the distance formula, we can find the distance between R and S and distance between TU.
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
h = 1 units
b = 6 units
Area of triangle RST = (1/2)(6×1) = 3 square units
Thus, the area of the triangle RST is 3 square units if the triangle RST has points (-3, 2), (3, 2), and (-1, 1). An altitude is drawn from point T to point U at (-1, 2).
