Measurement:

Measurement is the process of comparison of an unknown quantity with a known or standard quantity.

Given,

Mr. Customs is correcting the class’s math homework on customary units. Here we need to find which of the following measurements is reasonable.

By looking at the given options,

A) a pencil is 12 feet long - This one is wrong because the measuring unit of pencil is cm.

B) the back porch is 12 inches wide - For this one we have to use the feet or meter scale.

C) the 3rd hole in the golf course is is 123 miles long - Here this one we have to use either cm or mm.

Therefore, option (D) the distance from New York to California is 2,250 miles is a reasonable statement.

Answer:

X intercept: (-3/4 , 0)

Y intercept: (0 , 3/7)

Step-by-step explanation: The x intercept is a coordinate whenever y is 0. The y intercept is a coordinate whenever x is 0. So to find the x intercept you put 0 in place of Y and you solve for x. So you get x=-3/4.

You do the same thing to find Y, but you put 0 instead of x and you get y=3/7.

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 remainder for the given polynomial is 9

A polynomial is an expression made up of variables, constants, and exponents that are combined using mathematical operations like addition, subtraction, multiplication, and division (No division operation by a variable). It is a function that only uses non-negative integer powers or positive integer exponents of a variable

Given f(x) = 4x^6+ x^4+4

Now f(x-1) = 0

X= 1

Substitute the x value in the function

f(x) = 4x^6+ x^4+4

f(x) = 4(1)^6+ (1)^4+4

f(x) = 4+ 1+ 4

The product of the given polynomials is 4y/(y + 3).

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)]

The equation of the graphed line is written as: y = 2x + 2.

The equation of a graphed line can be determined by calculating the slope of the line, m = rise/run, and determining the y-intercept value, b, which is the point at which the line intersects the y-axis.

Using two points on the graphed line in the diagram attached below, (-4, -6) and (2, 6):

Slope (m) = change in y / change in x = (-6 - 6) /(-4 - 2)

Slope (m) = -12/-6

Slope (m) = 2

The line cuts the y-axis at y = 2. The y-intercept of the line, b = 2.

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”.

The percentage of jerseys that were medium-sized jerseys is 35.71%

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

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.
