20/4 means 5 * 4 = 20

x = 1475/25
x = 59 <== 59 boxes of diapers were bought
==============
18h + 70(36) = 4608
18h + 2520 = 4608
18h = 4608 - 2520
18h = 2088
h = 2088/18
h = 116....she did 116 haircuts
=================

The table below represents a linear function f(x) and the equation represents a function g(x):
x f(x)
−1 -12
0 -6
1 0

g(x)
g(x) = 2x + 6


Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)

Part B: Which function has a greater y-intercept? Justify your answer. (4 points)

Answers

PART A)
if f(x) is a line, you can find this expression:

y = m * x + b

Substitute two values to find, m and b. m is the slope, b the intercept, OK?

(0,-6) ---> -6 = b, so b= -6.
(1, 0) ---> 0 = m + b = m - 6, m = 6.

f(x) = 6x-6.

Check it:

(-1,-12)? y = 6*(-1)-6 = -12, yeah!!!

Now, g(x) is written as slope-intercept already:

slope = 2 (the coefficient of x)
intercept = 6 (the term without x)

slope of f(x) =6, slope of g(x) = 2

PART B)

6>-6, so the intercept of g(x) is greater.

the distance around the tire or a motorized scooter is 21.98. the tires make one revolutioneer 1/10 second.Find the speed of the scooter in miles per hour.

Answers

for every 1/10 second it travels 21.98 inches

for a full second it travels 21.98 x 10 = 219.8 inches

for 1 minute it travels 219.8 x 60 = 2820 inches / 12 = 235 feet per minute

 235*60 = 14100 feet per hour

5280 feet per mile

14100/5280 = 2.67 = 2.7 miles per hour

The speed of the scooter with a tire circumference of 21.98 inches rotating at 1/10 second per revolution is approximately 12.5 mph after converting the distance traveled in inches per second to miles per hour.

To calculate the speed of the scooter in miles per hour, we first need to determine how far the scooter travels in 1 second. Since the tires make one revolution every 1/10 of a second, and the distance around one tire is 21.98 inches, in one second the tire will cover a distance equal to 10 revolutions (because 1 second divided by 1/10 second per revolution equals 10 revolutions). Hence, the scooter travels 21.98 inches  imes 10 revolutions = 219.8 inches per second.

To convert this speed to miles per hour, we'll first convert inches to miles (1 mile = 63,360 inches), then seconds to hours (1 hour = 3600 seconds).

Calculate Miles per Hour
Speed in miles per second = 219.8 inches/s  imes (1 mile / 63360 inches) = 0.003468 miles per second.
Speed in miles per hour = 0.003468 miles/s  imes 3600 s/h = 12.4848 mph.

Therefore, the speed of the scooter is approximately 12.5 mph.

A carton of juice shaped like a rectangular prism measures approximately 8 inches high and 4 inches along each edge. A cylindrical glass that is 3 inches in diameter is filled to a height of 3.5 inches. Approximately how many glasses of this juice can be poured from a full container? Use π π = 3.14.

Answers

Volume of a rectangular prism is
V = length × width × height

The volume of the carton juice is
V = 4 × 4 × 8 = 128 in³

Volume of a cylinder is
V = Area of circular base × height = [tex] \pi r^{2} [/tex]×h, where [tex]r[/tex] is the radius of the circular base

The volume of the cylindrical glass is
V = (1.5)² × 3.14 × 3.5 = 24.7275 in³

Hence, the number of glasses that can be filled with the juice from the carton is:

128 ÷ 24.7275 = 5.18 ≈ 5 glasses

Jeremy drew a polygon with four right angles and four sides with the same length. Name all the polygons that he could have drawn.

Answers

he could have only drawn a square

Jeremy drew a square, which is a regular polygon with four equal sides and four right angles.

If Jeremy drew a polygon with four right angles and four sides of the same length, he could have drawn a square. This is because a square is the only regular polygon with four sides (also known as a quadrilateral) that has all sides equal in length and all angles equal at 90 degrees. In a quadrilateral, the sum of all interior angles is 360 degrees, which satisfies the criteria of having four right angles, as each right angle measures 90 degrees. The shape Jeremy drew cannot be any other polygon since the definition of a square is specific to having all sides equal and all angles equal, which uniquely identifies it among four-sided polygons.

The vertices J(2,6), K(7,8), L(9,3), and M(?, ?) determine a square. Show your work to find the coordinates of M. Use complete sentences and proper grammar to give a justification why JKLM is a square.

Answers

The sketch of the square JKLM is shown in the diagram below, which also tells us the coordinate of M = (4, 1). Plotting the coordinate on a graph is the most efficient way to work out the coordinate of M.

Mathematically, JKLM is a square because all of its four sides are equal in length. We also can justify by measuring the interior angles. A further method of justifying that JKLM is a square is by showing the lines connecting at each vertex are perpendicular.

In order to build a scale model of the trail, the drawing is enlarged on the coordinate plane. If two corners of the trail are at point A(−2, 7) and point D(−10, −1), what is another point that could represent a corner of the trail?
(10, 7)
(14, 7)
(12, 7)
(8, 7)

Answers

From the coordinate plane, we can see that the enlarged point A refers to point F, and enlarged point D refers to point I. To solve for this problem, we know that the ratios of each side should be similar (both the original and enlarged). Since the given choices have all y values equal to 7, so we have to look for the enlarged point of point G. Let us call that point as point C.

In this case, we take the ratio of side IF and side FG. First solving for length using distance formula:

IF^2 = (2 – 4)^2 + (-4 - -2)^2

IF^2 = 8

IF = sqrt 8

 

FG^2 = (7 – 4)^2 + (-2 - -2)^2

FG^2 = 9

FG = 3

 

Therefore the ratio of IF/FG must be equal to the ratio of DA / AC:

IF / FG = DA / AC

Find DA first:

DA^2 = (-10 - -2)^2 + (-1 -7)^2

DA^2 = 128

DA = sqrt 128

So,

sqrt 8 / 3 = sqrt 128 / AC

AC = 12

 

Finding for point C:          y  of point C = 7

AC^2 = (x - -2)^2 + (7 – 7)^2

12^2 = (x + 2)^2

x + 2 = 12

x = 10

Write a conjecture for the pattern of the sequence

Answers

Final answer:

To conjecture a sequence, one must identify and extend the observable pattern, much like the quark hypothesis predicted unseen particles, or like recognizing the vowel sounds in specific linguistic patterns.

Explanation:

In mathematics, creating a conjecture for a sequence involves analyzing the given numbers or patterns and predicting the next element based on the identified pattern. The process comparable to what the developers of the quark hypothesis did, working to predict unknown elements based on established patterns, can aid us in formulating a conjecture for the sequence in question.

For instance, if we refer to the resonance frequencies of a closed tube which form a pattern represented by the formula An = L / (4n) where n is an odd number, we can conjecture that the next frequency in the sequence would be determined by the next odd integer following the last one used.

Similarly, the binomial theorem expansion shows a pattern of coefficients that can be used to conjecture future terms in a binomial expansion. Analyzing patterns like VCC and VCle that determine whether the vowel sound should be long or short in English offer a linguistic parallel to mathematical pattern predictions.

Final answer:

To create a conjecture for a sequence, examine the values and look for a consistent relationship or rule. An example is adding 3 to the previous term in the sequence.

Explanation:

A conjecture for the pattern of a sequence can be created by examining the values in the sequence and looking for a consistent relationship or rule. For example, if the sequence is 1, 4, 7, 10, 13, the conjecture may be that each term is obtained by adding 3 to the previous term. This can be represented mathematically as An = A(n-1) + 3, where An represents the nth term in the sequence.

How fast was Matt driving if he drove 415 miles in 7 hours?

Answers

He was driving 59 mph

The speed of Matt nearest to tenth place will be 59.3 miles per hour.

What is speed?

Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.

We know that the speed formula

Speed = Distance/Time

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

Matt drove 415 miles in 7 hours. Then the speed of Matt is calculated as,

Speed = 415 / 7

Simplify the equation, then we have

Speed = 59.2857 miles per hour

Speed = 59.3 miles per hour

The speed of Matt closest to the 10th spot will be 59.3 miles each hour.
