Number four please and please explain how to find perimeter only using vertices
Answers
you could use a graphing calculator (physical or online, i use desmos) or just graph it or use the distance formula between all the points (which would take a long time) and if you did decide to do that remember to use logic because finding the distance between the two opposite diagonal points is not part of the perimeter or finally you could count between the points, but like the distance formula only between the points that are going to be a part of the perimeter.

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
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

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

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.

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
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.

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

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
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.
