The equation of circles that have a diameter of 12 units and a center that lies on the y-axis is (x + 6)² + y² = 144
What is the equation of a circle?The equation of a circle with center (h, k) and radius r is given by
(x - h)² + (y - k)² = r²
To determine which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis, we must have that
for the circle to lie on the y - axis, k = 0 and r² = 144
So, comparing the equations that meet this criteria, we have
(x + 6)² + y² = 144
We cannot select the circle (x – 4)² + y² = 36. Although it lies on the y - axis, its radius is not equal to 12.
So, the circle is (x + 6)² + y² = 144

2) The volume of the second rectangular prism is 60ft³
3) The volume of the third rectangular prism 140ft³
4) The volume of the Fourth rectangular prism 216ft³
What is the rationale for the above response?Note that in order to find the volume of area of a complex figure, you must deconstruct it into manageable proportions.
Shape 1 above, we deconstructed the rectangular prism into two 3 dimensional shapes with the following metrics:
a)
Length = 7ft
Height = 2ft
widht = 2ft
Volume = Volume = 7ft x 2ft x 2ft
Volume = 28 ft³
b)
Length = 7ft
Height = 3ft
width = 7ft
Volume = 147 ft³
Total Volume = 28 ft³ + 147 ft³
Volume for Shape 1 = 175 ft³

Select the graph that represents the solution of the compound inequality –6 ≤ 4x + 6 < 14
By answering the above question, we may state that The range of -3 x 2 inequality is the answer to the compound inequality.
What is inequality?A connection between two expressions or values that is not equal in mathematics is referred to as an inequality. Hence, inequity results from imbalance. In mathematics, an inequality establishes the connection between two non-equal numbers. Egality and inequality are not the same. Use the not equal symbol most frequently when two values are not equal (). Values of any size can be contrasted using a variety of inequalities. By changing the two sides until just the variables are left, many straightforward inequalities may be solved. Nonetheless, a variety of factors support inequality: Both sides' negative values are split or added. Exchange the left and the right.
We must first remove 6 from each of the three elements of the compound inequality -6 4x + 6 14 in order to arrive at the following result:
-6 - 6 ≤ 4x < 14 - 6
If we simplify, we get:
-12 ≤ 4x < 8
Then, we divide each of the three inequality components by 4, keeping in mind that we don't need to reverse the inequality's signs because 4 is positive, to arrive at:
-3 ≤ x < 2
The range of -3 x 2 is the answer to the compound inequality.

The product will be larger than both factors.
The product will be larger than the smaller factor but smaller than the larger factor.
The product will be smaller than both factors.
The product will be an improper fraction.
Answer:
When two proper fractions are multiplied together, the product will be smaller than both factors.
Step-by-step explanation:
To understand why this is true, we can consider the concept of fractions as parts of a whole. When we multiply two proper fractions, we are essentially taking a part of a part, which results in a smaller portion overall.For example, if we multiply 1/2 by 2/3, we are taking half of something and then taking two-thirds of that half. The result is 1/3, which is smaller than both 1/2 and 2/3.Therefore, the correct answer is: The product will be smaller than both factors.
Answer:The product will be smaller than both factors.
When two proper fractions are multiplied together The product will be smaller than both factors.Take a look at the equation below.
¾ * ⅔= 3 times 2 is 6 and 4 times 3 is 12. So the equation is 6/12 .
6/12 is simplified to 1/2. 1/2 is less than both 2/3 and 3/4. Which means the product is smaller. Hence, the correct answer is the product will be smaller than both factors.

The probability of F P(F) = 0.33 and the conditional probability of F given G P(F|G) = 0.24. F and G is associated since they are not independent.
What is conditional probabilityConditional probability is known as the possibility of an event or outcome happening, based on the existence of a previous event or outcome. The conditional probability P(A|B) occur only in the case of dependent events. It gives the conditional probability of A given that B has occurred.
P(F|G) = P(F∩G) / P(G)
P(F∩G) = Probability of happening of both F and G
P(F) = 199/600 = 0.3317
P(F∩G) = 79/600 = 0.1317
P(G) = 330/600 = 0.55
P(F|G) = 0.1317/0.55
P(F|G) = 0.2394.
Two events say A and B are independent if the probability of occurrence of one of them is not affected by the occurrence of the other, mathematical expressed as P(A ∩ B) = P(A) × P(B)
P(F) × P(G) = 0.3317 × 0.55
P(F) × P(G) = 0.1824
P(F∩G) is not equal to P(F) × P(G) from the data given.
Therefore, the probability of F P(F) = 0.33 and the conditional probability of F given G P(F|G) = 0.24. F and G is associated since they are not independent.

What is the value of cos^-1 (-square root 3/2)
Answer:
Step-by-step explanation:
The value of cos^-1(-sqrt(3)/2) is -π/6 or -30 degrees.
We know that cos^-1(x) gives the angle whose cosine is x, in the range [0, π]. In this case, we are looking for the angle whose cosine is -sqrt(3)/2.
Recall that the cosine function is negative in the second and third quadrants of the unit circle. In the second quadrant, the reference angle whose cosine is sqrt(3)/2 is π/6 or 30 degrees, but the cosine function is negative in this quadrant. Therefore, the angle whose cosine is -sqrt(3)/2 is -π/6 or -30 degrees, which is in the fourth quadrant.
So, cos^-1(-sqrt(3)/2) = -π/6 or -30 degrees.

The Clarke's son suggests that they rent a car that costs $250 for the week plus $0.22c/km. Their daughter does not want to drive far, so she suggests a car that is only $96 for the week but $0.50/km.
a) Write an equation to represent the cost of the car suggested by the son
b) Write an equation to represent the cost of the car suggest by the daughter
c) When will the two cars cost the same? Used the method of elimination to solve.
d) If the Clarke's plan to drive 500km, which option is less expensive?
Answer: a) The equation to represent the cost of the car suggested by the son is:
C1 = 250 + 0.22k
where C1 represents the total cost of renting the car, and k represents the number of kilometers driven.
b) The equation to represent the cost of the car suggested by the daughter is:
C2 = 96 + 0.5k
where C2 represents the total cost of renting the car, and k represents the number of kilometers driven.
c) To find when the two cars cost the same, we need to solve the equation:
C1 = C2
Substituting the expressions for C1 and C2 from parts a and b, we get:
250 + 0.22k = 96 + 0.5k
Simplifying this equation, we get:
0.28k = 154
Dividing both sides by 0.28, we get:
k = 550
Therefore, the two cars cost the same when the number of kilometers driven is 550.
d) If the Clarke's plan to drive 500km, we can calculate the total cost for each car by substituting k=500 into the equations from parts a and b:
C1 = 250 + 0.22(500) = 360
C2 = 96 + 0.5(500) = 346
Therefore, the car suggested by the daughter is less expensive for a 500km trip, as it would cost $346 compared to $360 for the car suggested by the son.

Answer:
15 ft
Step-by-step explanation:
Use the Pythagorean theorem.
9² + 12² = c²
c² = 225
c = √225 = 15
Answer: 15 ft
Answer:
15 feet
Step-by-step explanation:
So, to start we have to find the area of the wall.
9(12)=108
Now, we need to find half of the walls area
108/2=54
We have our length and height, but we need to find the hypotenuse using Pythagoreans theorem.
9 is our A and 12 is our B
a^2+b^2=c^2
81+144=c^2
c^2=225
The square root of 225 is 15.
C=15
Therefore, the stripe will be 15 feet.

Number of Garments

15
Company 1
$55.25
$75.50
$95.75
Company 2
$31.25
$57.50
$83.75
The ordered pair representing the point where both companies would charge the same amount is (25, 136.25).
When would both companies charge the same amount?
From the given table, we can form the following equation for monthly cost of each company.
Company 1, the function for the monthly cost is;
(5, $55.25 ) and (10, $75.5). Let the monthly cost = y₁
(y₁ - 55.25 )/(x - 5) = ( 75.5 - 55.25 )/ (10 - 5)
y₁ = 4.05x + 35
Company 2, the function for the monthly cost is;
(5, $31.25 ) and (10, $57.5). Let the monthly cost = y₂
(y₂- 31.25 )/(x - 5) = ( 57.5 - 31.25 )/ (10 - 5)
y₂ = 5.25x + 5
To find the point where both companies charge the same amount, we need to set their costs equal to each other and solve for the number of garments, x:
y₁ = y₂
4.05x + 35 = 5.25x + 5
Subtracting 4.05x and 5 from both sides:
30 = 1.2x
Dividing both sides by 1.2:
x = 25
So both companies would charge the same amount when 25 garments are laundered. T
To find the cost, we can plug x = 25 into either equation:
y₁ = 4.05(25) + 35 = 136.25
y₂ = 5.25(25) + 5 = 136.25
