What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
3x + 4 = 5 is an equation.
2x + 4x = 4 is an equation.
We have,
The function f(x) represents the amount of money Barrett earns per gallon of ice cream, where x is the number of gallons of ice cream he makes.
The function g(x) represents the number of gallons of ice cream Barrett makes per hour, where x is the number of hours he works.
f(x) = 2x² + 4
g(x) = √(3x³)
Now,
f(g(x)):
= f(√(3x³))
= 2{√(3x³)}² + 4
= 2(3x³) + 4

We are given two polynomials. A polynomial is a mathematical statement that is composed of the sum of powers in one or more variables multiplied by coefficients. The polynomials are in rational form. A rational number is created by dividing an integer by an integer. The first polynomial is 2y/(y - 3). The second polynomial is (4y - 12)/(2y + 6). We need to find the product of these two polynomials. Let the product be represented by the variable "P".
P = [2y/(y - 3)]×[(4y - 12)/(2y + 6)]

ANSWER ASAP A basketball team played six games. In those games, the team won by 8 points, lost by 8, won by 7, won by 10, lost by 2, and won by 9. What was the mean difference in game scores over the six games?
The average difference or mean in game scores across six games is 5.67
MeanThe mean is the average of a data set. The mode is the most common number in a data set. The median is the middle of the set of numbers. The mean is the average or the most common value in a collection of numbers. the mean is one of the measures of b, apart from the mode and median. Mean is nothing but the average of the given set of a data.
To solve this problem, we have to write the wins and loss separate and then find the mean.
Wins = 8 points, 7 points, 20 points, 9 points
Loss = 8 points, 2 points
The sum of win points = 8 + 7 + 20 + 9 = 44 points
The sum of lost points = 8 + 2 = 10 points
The mean difference = (win - loss)/ total number of games
The mean difference = ( 44 - 10) / 6
The mean difference = 34 / 6 =5.67
The mean difference in the game scores over six games is 5.67 points

Is the absolute value of -3 less than, greater than, or equal to -7
The statements are true "3 is less than 7, and the absolute value of 3 is less than the absolute value of 7".
What is absolute value?Absolute value is defined as the magnitude or size of a number, no negatives are allowed.
The distance a number is from 0 on the number line is known as the absolute value of the number.
For example, |5| is 5 because it is 5 units away from 0. Also, |-5| is also 5 because -5 is 5 units from 0.
The absolute value of a number is how distant it is from zero. The standard procedure to represent absolute value is to use a number line to estimate the exact distance the number is from zero.
As per the option, 3 is less than 7 is true.
The absolute value of 3 is less than the absolute value of 7 is true.

The closed right circular cylindrical can of the smallest surface area whose volume is
250 π cm3 has a radius of _____ cm and a height of _____ cm
The closed right circular cylindrical can of the smallest surface area whose volume is 250π cm³ has a radius of 5cm and a height of 10 cm.
Let r and h be the radius and height of the cylinder respectively.
Volume, V= πr²h
Given,
Volume = 250 π
Now, we can solve by:
⇒ 250 π = πr²h
⇒ r²h=250
⇒ h= 250/r²
We know that,
Surface area, A = 2πr²+2πrh
⇒ A = 2πr²+ 2πr(250/r²)
⇒ A = 2πr²+ (500π/r)
Differentiating the above equation,
dA / dr = 4πr+500π(-1/r²)
For A to be maximum or minimum, dA/dr = 0
⇒ 4πr-500(π/r²) = 0
⇒ 4πr - 500π / r² = 0
⇒ 4πr³ -500π/ r² = 0
⇒ π (4r³ -500) = 0
⇒ 4r³ - 500 = 0
⇒ r = ∛125
⇒ r = 5
Putting value of r = 5, we get,
h = 250/(5)² = 10
By second derivative test,
d²A/dr² = 4π-500π(-2/r³)
At r= 5,
d²A/dr² = 4π+1000(π/r³) > 0 .
Therefore, It is a local minimum.

The cost of 4kg of kale and 1.5 kg of beetroot is 12.20
The cost of 5kg of kale and 2kg of beetroots is 15.40 work out the cost of 1kg of beetroot and 1kg of kale
The cost of 1 kg of beetroot and 1 kg of kale are 1.39 units and 2.53 units respectively
How to find the cost of beetroot and Kale?The cost of 4kg of kale and 1.5 kg of beetroot is 12.20. The cost of 5kg of kale and 2kg of beetroots is 15.40.
The cost of 1kg of beetroot and 1kg of kale can be found as follows:
Therefore,
let
x = cost of 1kg of beetroot
y = cost of 1 kg of Kale
Therefore, using equation,
1.5x + 4y = 12.20
2x + 5y = 15.40
x = 12.20 / 1.5 - 4y / 1.5
x = 8.13 - 2.67y
Hence,
5y = 15.40 - 2(8.13 - 2.67y)
5y = 15.40 - 16.26 + 5.34y
5y = -0.86 + 5.34y
5y - 5.34y = -0.86
- 0.34y = - 0.86
y = - 0.86 / - 0.34
y = 2.52941176471
y = 2.53
1.5x = 12.20 - 4(2.53)
1.5x = 12.20 - 10.12
1.5x = 2.08
x = 2.08 / 1.5
x = 1.38666666667
x = 1.39
Therefore,
cost of 1kg of beetroot ≈ 1.39

What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Total number of jerseys the football team has = 28 jerseys
Total number of jerseys that were medium sized = 10
So ,
Percentage of jerseys that were medium sized =
( Total number of jerseys that were medium sized / Total number of jerseys ) x 100
Percentage of jerseys that were medium sized = ( 10 / 28 ) x 100
= ( 5 / 14 ) x 100
= 7.14285 x 5

50 Points!!! Explain the difference between consecutive interior angles, corresponding interior angles, and co-interior angles.
Answer:
Co-interior angles or Consecutive interior angles are the two angles that are on the same side of the transversal. Co-interior angles are the interior angles and it sums up to 180 degrees. It means that the sum of two interior angles, which are on the same side of transversal is supplementary. Co-interior angles resemble like in “C” shape and both the angles are not equal to each other. The co-interior angle is also known as the consecutive interior angles or the same side interior angles.Co-interior Angles
Co-interior Angle Theorem and Proof
Statement:
If the transversal intersects the two parallel lines, each pair of co-interior angles sums up to 180 degrees (supplementary angles).
Proof:
Co-interior Angles Proof
Let us consider the image given above:
In the figure, angles 3 and 5 are the co interior angles and angles 4 and 6 are the co-interior angles.
To prove: ∠3 and ∠5 are supplementary and ∠4 and ∠6 are supplementary.
Given that, a and b are parallel to each other and t is the transversal.
By the definition of linear pair,
∠1 and ∠3 form the linear pair.
Similarly, ∠2 and ∠4 form the linear pair.
By using the supplement postulate,
∠1 and ∠3 are supplementary
(i.e.) ∠1 + ∠3 = 180
Similarly,
∠2 and ∠4 are supplementary
(i.e.) ∠2 + ∠4 = 180
By using the corresponding angles theorem, we can write
∠1 ≅∠5 and ∠2 ≅ ∠6
Thus, by using the substitution property, we can say,
∠3 and ∠5 are supplementary and ∠4 and ∠6 are supplementary.
Hence, the co-interior angle theorem (consecutive interior angle) is proved.
The converse of this theorem is “if a transversal intersects two lines, such that the pair of co-interior angles are supplementary, then the two lines are parallel”.
