Which is constant term in the equation given in standard from 5x+3y=15
Given the equation (x - 13) ^ 2 + y ^ 2 = 64 identify the center and radius
Answer:
radius is 8; center is at (13, 0).
Step-by-step explanation:
Compare the given (x - 13) ^ 2 + y ^ 2 = 64 to:
(x - h)^2 + (y - k)^2 = r^2. (h, k) represents the center
and r the radius.
Since 64 = r^2, r = the radius = 8 units = r
We also see that h = 13 and k = 0.
Thus, the center of the given circle is (13, 0).
5x - 6y = 4

Joe is commissioned to build a small rectangular garden area on community property. The landscape committee requested that the garden be 10 feet longer than it is wide. Joe has up to 90 feet of material to use for the perimeter. What is the maximum width w of the garden?
Write an expression that represents the length of the garden.
Write the inequality that models the perimeter of the garden.
Solve the inequality.
Answer:
length = width + 10
4*width + 20 ≤ 90
width ≤ 17.5 feet
Step-by-step explanation:
The perimeter of a rectangle is given by:
Perimeter = 2*length + 2*width
The length needs to be 10 feet longer than the width, so we have:
length = width + 10
Using this length in the perimeter equation, we have:
Perimeter = 2*(width + 10) + 2*width = 4*width + 20
The perimeter needs to be up to 90 feet, so we have:
P ≤ 90
4*width + 20 ≤ 90
4*width ≤ 70
width ≤ 17.5 feet
the maximum width of the garden is 17.5 feet
You pay $8 to play the following game of chance. There is a bag containing 15 balls, 7 are red, 6 are green and the rest are yellow. You will win $14 if you draw a yellow ball, and $11 if you draw a green ball. What is the expected value of the game?
Answer:
Green ball. $11
Step-by-step explanation:
Let's see.
15 balls. 7 are red. 6 are green. rest are yellow. That means there are 2 yellow balls.
Since there are more greens than yellows, you have a better chance of getting a green. That means you have a higher chance of getting $11
The total expected value of the game is $2 if you pay $8 to play the following game of chance.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
You pay $8 to play the following game of chance. There is a bag containing 15 balls, 7 are red, 6 are green and the rest are yellow.
Yellow balls = 15 - 7 - 6= 2
Probability of yellow = 2/15
Probability of green = 6/15
Expected value of the game = 6(2/15) + 3(6/15) = $2
Thus, the total expected value of the game is $2 if you pay $8 to play the following game of chance.

Answer:
Not widely used. If you continue to increase an angle it will eventually 'double back' on itself and form a full 360° angle. This is the Full Angle. One could argue that this is the same as a zero-sized angle. But we generally mean the reflex angle and so it is a full circle or 360°. Adjust the angle above and try to create the full angle going around in both directions.

1. Mr. Smith visited the park one sunny afternoon. He noticed that only
dogs and people were in the park that day. While he was resting on a park
bench, he observed that there were 15 heads and 50 legs in the park.
Which pair of system of equations can be used to determine the number
of dogs and the number of people in the park that day (use x = # of people;
y = # of dogs)?
x + y = 50: 2x + 4y = 15
x + y = 15, 4x + 2y = 50
X + y = 15:2x + 4y = 50
x + y = 50; 4x + 2y = 15
Answer:
x+y=15 ; 2x+4y=50
Step-by-step explanation:
Let x be the number of people
Let y be the number of dogs.
Equation regarding Total Heads:Total number of heads = 15
As
1 person has 1 head
1 dog has 1 head
Total no. of heads of people = 1 * x = x
Total number of heads of dogs = 1*y = y
Equation becomes:
x+y=15
Equation regarding Total Legs:Total number of legs = 50
As
1 person has 2 legs
1 dog has 4 legs
Total no. of legs of people = 2 * x = 2x
Total number of legs of dogs = 4*y = 4y
Equation becomes:
2x+4y=50

A school has a square playground with each side
measuring 120 feet. A scale drawing of the
playground uses the scale = inch equals 12 feet.
What is the length of a side of the playground on
this scale drawing?
Help!
Answer:
10 inches
Step-by-step explanation:
The length of the playground in its actual size is 120 feet.
The scale drawing uses a scale of 1 inch to 12 feet.
This means that 1 inch in the drawing equals 12 feet in actual size.
Therefore, the length of the playground on the scale drawing is:
1 inch = 12 feet
x = 120 feet
Cross-multiply:
120 * 1 = 12 * x
=> x = 120 / 12 = 10 inches
The length of a side of the playground on the scale drawing is 10 inches.
The probability that a person has immunity to a particular disease is 0.6. Find the mean number who have
immunity in samples of size 12.
Answer:
Step-by-step explanation:
This is a binomial probability problem. There are only two outcomes. It is either a chosen person has immunity to a particular disease or he does not. The probability of success in this case, p is the probability that a chosen person has immunity to a particular disease. Thus
p = 0.6
The probability of failure, q is q = 1 - p
Thus, q = 1 - 0.6 = 0.4
Mean = np
Where n represents sample size. Thus,
Mean = 12 × 0.6 = 7.2

Graphs of functions on the interval [−4, 4] are depicted below. For each function, find:
1) The domain
2) Zeros of a function (the values of x where the function is zero)
3) Intervals where the function is positive and intervals where it is negative
Answer:
Domain : [-4,4} or [tex]-4\leq x\leq 4[/tex]
Zeros of the function: (-2, 0, 2)
Intervals when function is positive: (0,2)
Intervals where function is negative: (-4,0), (2,4)
Step-by-step explanation:
Domain can be defined as the input of all possible values of x in the given interval. We can se from the graph that minimum value of x is -4 while maximum value of x is 4. So
[tex]-4\leq x\leq 4[/tex]
The value of function becomes 0 at three places, when x becomes -2,0 or 2
We can see that the function is negative throughout the interval (-4,0), then it become positive from (0,2), then it becomes negative again from (2,4)
/ / * ANSWER PLS * / / MK and ML are tangent to circle J. If MK = 6x – 15 and ML = 2x + 9, find x.
Answer:
x=6
Step-by-step explanation:
As MK and ML are tangent to the circle, they are also congruent (MK = ML). Thus we can set the equation:
6x-15 = 2x+9
Now solve for x:
6x-2x = 9+15
4x=24
x=6
Answer:
B.
Step-by-step explanation:
MK and ML are tangents to a circle and " originating from the same point" so
MK=ML
Since MK = 6x-15 and ML = 2x+9
So,
6x-15 = 2x+9
6x-2x = 9+15
4x = 24
Dividing both sides by 4
So, we'll get
x = 6

PLEASE HELP ME FOR BRAINLIEST ANSWER An architect designs a rectangular flower garden such that the width is exactly two-thirds of the length. If 280 feet of antique picket fencing are to be used to enclose the garden, find the dimensions of the garden. The length of the garden is ? feet.
Answer:
Length: 84 ft
Width: 56 ft
Step-by-step explanation:
Let's define some variables first.
Call the length l and width w.
We know that w = 2/3l. Therefore, we can express w in terms of l with this expression.
Now, let's set up an equation. The flower garden is rectangular, and 280 feet of fencing are used to enclose the garden. This represents perimeter.
Remember the formula for perimeter of a rectangle: 2l + 2w
Let's substitute 2/3l for w:
2l + 2*2/3l = P
2l + 4/3l = 280
2 4/3l = 280
10/3l = 280
l = 84
Now, we know that the length is equal to 84 feet. We can multiply 84 feet by 2/3 to find the width.
84*2/3 = 56
Length: 84 ft
Width: 56 ft
Let's plug these values into the formula and see if they give us the correct perimeter:
2l + 2w = P
2*84 + 2*56 = P
168 + 112
= 280 feet
These are the correct dimensions!

Answer:
Any integer x can be represent in form of 3k, 3k+1, or 3k + 2 (k is integer).
Case 1: x = 3k => x^2 - 2 = 9k^2 - 2, which will not be divisible by 3
(notice that 2 is not divisibble by 3, but 9k^2)
Case 2: x = 3k + 1 => x^2 - 2 = 9k^2 + 6k + 1 - 2 = 9k^2 + 6k - 1, which will not be divisible by 3
(notice that 1 is not divisibble by 3, but 9k^2 + 6k)
Case 3: x = 3k + 2 => x^2 - 2 = 9k^2 + 12k + 4 - 2 = 9k^2 + 12k - 2, which will not be divisible by 3
(notice that 2 is not divisibble by 3, but 9k^2 + 12k)
