which equation represents a circle with a center at (-3,5) and a radius of 6 units
Answer:
(x+3)^2 +(y-5)^2 = 36
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 +(y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x- -3)^2 +(y-5)^2 = 6^2
(x+3)^2 +(y-5)^2 = 36

What is the area of this figure
Given:
Image of the figure.
To find:
The area of the figure.
Solution:
Length of larger rectangle = 9
Width of larger rectangle = 8
Area of larger rectangle = length × width
= 9 × 8
Area of larger rectangle = 72 square units
Length of smaller rectangle = 4
Width of smaller rectangle = 2
Area of smaller rectangle = length × width
= 4 × 2
Area of smaller rectangle= 8 square units
Area of the figure = Area of larger rectangle - Area of smaller rectangle
= 72 - 8
= 64 square units
The area of the figure is 64 square units.
reflection across the x-axis
K(1, −1), N(4, 0), Q(4, −4)
The reflection across the x-axis changes the y-coordinate to its opposite. Thus, K(1, −1) becomes K(1, 1), N(4, 0) doesn't change, and Q(4, −4) becomes Q(4, 4).
The question's task is a reflection across the x-axis. This change involves flipping the coordinates in the plane over the x-axis. For a given point with coordinates (x, y), its reflection will have coordinates (x, -y). Let's apply this rule to the points given:
K(1, −1) will become K(1, 1)
N(4, 0) will remain N(4, 0) because it lies on the x-axis
Q(4, −4) will become Q(4, 4)
So, the reflected coordinates are K(1, 1), N(4, 0), Q(4, 4).

What is the length of side PQ in this figure?
Answer:
C
Step-by-step explanation:
o find the side PQ ; we need to first find the length of the given line segment which is perpendicular to side PR; let name it as QS.
Now as ΔQSR is an right angled triangle.
and the length of the side QR and SR is given , so using Pythagorean theorem we have
QR^{2}=SR^{2}+QS^{2}
5^{2}=3^{2}+QS^{2}\\ \\QS^{2}=5^{2}-3^{2}\\\\QS^{2}=25-3=16=4^2
⇒ QS=4
Now again ΔQSP is an right angled triangle; so using Pythagorean theorem in ΔQSP we have
PQ^{2}=QS^{2}+PS^{2}\\ \\PQ^{2}=4^{2}+6^{2}=16+36=52
This means QS=\sqrt{52}=2\sqrt{13}
Hence, the length of side PQ is \sqrt{52}=2\sqrt{13}.
Hence, option C is correct.

Laura mowed 8 lawns. She earned $12, $10, $15, $15, $15, $10, and $9 for seven lawns. How much did she earn the eighth time if the mean of the data is $12? *
Answer:
She earned $10 for mowing the 8th lawn.
Step-by-step explanation:
Let's use the average formula and n = 8, with x representing the 8th score:
12 + 10 + 15 + 15 + 15 + 10 + 9 + x
average = 12 = -------------------------------------------------
8
86 + x
Summing up the numerator, we get average = ----------- = 12
8
Multiplying both sides by 8 yields 86 + x = 96
Solving for x, we get x = 10.
She earned $10 for mowing the 8th lawn.
Answer:
She earned $10 for the eighth yard.
Step-by-step explanation:
You have 7 known numbers and 1 unknown giving you a total of 8 numbers. When doing mean, you add up all the numbers and divide by the amount of numbers you have (in this case 8). If you add all the numbers in this particular data set you get 86. You know that you have to divide by 8 and you need 12 to be the answer. Using multiplication facts, we know that 96 divided by 8 is equal to 12. That means the answer must be 10 for the eighth yard because 86+10=96.
A private club was reduced by 27 members in 3 weeks. Its size changed by the same number of members each week. What was the change in the club's size each week?
Final answer:
The club's size decreased by a total of 27 members over 3 weeks. By dividing 27 by 3, we find that the size changed by 9 members each week.
Explanation:
The question asks about a private club which lost 27 members over the course of 3 weeks, with an equal number of members leaving each week. To find the change in the club's size each week, we divide the total number of members who left by the number of weeks. This calculation is done by taking the total decrease in members, which is 27, and dividing it by the 3 weeks.
Identify the total decrease in members: 27.
Identify the total number of weeks: 3.
Divide the total decrease in members by the number of weeks: 27 members ÷ 3 weeks = 9 members per week.
Therefore, the club's size changed by 9 members each week.

Which of these equations has a y-intercept of 4?
A. y=x+4
B. y=x-4
C. y=4x
D. y+4=x
Answer:
A
Step-by-step explanation:
Since A is already in slope intercept form, we know that the b value is already in the correct place.
y = mx + b
In slope intercept form, the b is the y int.
Thank me later :)
Answer:
Option A, y = x + 4
Step-by-step explanation:
Step 1: Determine which option is correct
y = mx + b
m is the slope while b is the y-int
So... the equation with a 4 for b should be the correct answer.
Option A states the following: y = x + 4
This shows that the y-int is 4 and the slope is 1. So, this answer is correct.
Answer: Option A, y = x + 4

The symbol ≤ means less than or equal to. The symbol ≥ means greater than or equal to.The notation a ≤ b or a ⩽ b means that a is less than or equal to b (or, equivalently, at most b, or not greater than b). The notation a ≥ b or a ⩾ b means that a is greater than or equal to b (or, equivalently, at least b, or not less than b).The five inequality symbols in Maths are greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤), and not equal to symbol (≠).

Step-by-step explanation:
The area of the right triangle is
A =1/2 bh where b = (2+7) and h=(4+7)
=1/2(9)(11)
49.5
The area of the rectangle is
A = l*w where l is 2 and w is 4

The shaded region is the area of the triangle minus the area of the rectangle
A shaded = 49.5 - 8 = 41.5

A rectangle is always a square? True or false?
Answer:
False
Step-by-step explanation:
A square is defined as a quadrilateral with 4 congruent sides, but a rectangle is defined as a quadrilateral with 2 pairs of congruent sides, so unless the 2 pairs in a rectangle are the same length, no the rectangle is not a square. However all squares are rectangles.
"A rectangle is always a square" is false statement.
Rectangle:A rectangle is quadrilateral, in which opposite sides are equal in length and all four angles are equal to 90 degree.
A square is quadrilateral, in which all four sides are equal in length and all four angles are equal to 90 degree.
A square is always a rectangle, but a rectangle is not always a square.
Therefore, given statements is false.

Kesha threw her baton up in the air from the marching band platform during practice. The equation h(t) = −16t² + 54t + 40 gives the height of the baton, in feet, t seconds after it is thrown from the platform. What is the height of the platform? At what speed was the baton thrown? If she doesn't catch it, when will it hit the ground?
Answer:
(a)Height of the platform=40 feet
(b)Initial Velocity=54 ft/sec
(c)4 seconds
Step-by-step explanation:
The equation [tex]h(t) = -16t\² + 54t + 40[/tex] gives the height of the baton, in feet, t seconds after it is thrown from the platform.
(a)Height of the platform
The Height of the platform is the height at which t=0
[tex]h(0) = -16(0)\² + 54(0) + 40[/tex]
Height of the platform=40 feet
(b)To determine the speed at which the baton was thrown, we find the velocity, v(t).
[tex]v(t)=\frac{dh}{dt} =\frac{d}{dt} (-16t\² + 54t + 40)=-32t+54\\$At t=0\\v(0)=-32(0)+54=54 feet/sec[/tex]
(c)The baton will hit the ground when its height, h(t)=0
[tex]-16t\² + 54t + 40=0\\\text{Solving the quadratic formular}\\t = \frac{-54\pm \sqrt{(-54)^2 - 4*40*(-16)} }{2*-16}\\= \frac{-54\pm \sqrt{5476 }}{-32}\\= \frac{-54\pm 74}{-32}\\t=\frac{-54+ 74}{-32},\frac{-54- 74}{-32}\\t=-0.625\:or \:t=4[/tex]
Since -0.625 is not valid, the baton will hit the ground 4 seconds after it is thrown.
A right triangle has a hypotenuse of square root of 50. What are possible lengths of the two legs of this triangle?
For 45-45-90 degree triangle
The length of other two legs: 5
For 30-60-90 degree triangle
The shorter leg= 3.53
The larger leg = 6.11
Step-by-step explanation:
length of Hypotenuse = [tex]\sqrt{50}[/tex]
We need to find possible lengths of the two legs of this triangle.
If the triangle is 45-45-90 degree triangle the length of other two sides would be same and can be found by:
[tex]Length\,\,of\,\,leg:\frac{\sqrt{50} }{\sqrt{2} } \\Length\,\,of\,\,leg:5[/tex]
Since both legs are of same size so, length of other leg = 5
If the triangle is 30-60-90 degree triangle then:
To find shorter length: Divide hypotenuse by 2.
To find other side length: Multiply shorter length by [tex]\sqrt{3}[/tex]
The shorter leg = [tex]\frac{\sqrt{50} }{2}= 3.53[/tex]
The other leg (larger) = [tex]3.53\times \sqrt{3} =6.11[/tex]
