A taxi company charges an initial fee
of $2.80 plus $3.50 per mile traveled.
a. Does the situation represent a function? If so, identify
the independent and dependent variables.
b. You have enough money to travel at most 20 miles
in the taxi. Find the domain and range.
The situation is a function, & the independent and dependent variables are the number of miles and total fee, respectively
a. Does the situation represent a function? If so, identify the independent and dependent variables.The given parameters are
Initial Fee = $2.80
Rate = $3.50 per mile
Let the number of miles be x and the total fee be y
So, we have
Total fee = Initial Fee + Rate * Number of miles
This gives
y = 2.8 + 3.5x
This means that the situation is a function, & the independent and dependent variables are the number of miles and total fee, respectively
b. You have enough money to travel at most 20 miles in the taxi. Find the domain and range.Here, we have
Maximum number of miles = 20
This means that the domain is 0 <= x <= 20
Substitute 20 for x in y = 2.8 + 3.5x
y = 2.8 + 3.5 x 20
Evaluate
y = 72.8
This means that the range is 0 <= x <= 72.8

A department store advertises a sale where the customer chooses the discount. A customer may choose a flat discount of $20 off any purchase or 20% off the total purchase price. The final purchase price of an item was $175.
a. What are the possible prices of the item before each discount?
b. Which discount represents a bigger savings in cost for the customer?
The answers will be :
A. The possible prices at flat discount of $ 20 will be $195 and at flat discount of 20% will be $218.75
B. The discount of flat 20 % gives a bigger savings in cost for the customer.
What do you mean by discount ?
The discount is the difference between the purchase price and the item's par value or simply deduction from the cost price of a good.
It is given that the final purchase price of the item is $175.
A.
Let's try to find out the possible price of item before each discount.
So , price before discount can be calculated by using formula which is :
Price before discount = Discount + Final purchase price
As in first case the flat discount is of $20 , so :
Price before discount = $20 + $ 175
Price before discount = $195
Now as per the question , there is a flat discount of 20% off the total purchase price .
So , let's assume if price before discount is P then :
[ P - ( 20P / 100) ] = 175
P - 0.2 P = 175
0.8 P = 175
or
P = $ 218.75
B.
From the above calculations which we have done , we can conclude that the discount of 20 % represents a bigger savings in cost for the customer because customer is saving an amount of $218.75 which is greater than $195.
Therefore , the answers will be :
A. The possible prices at flat discount of $ 20 will be $195 and at flat discount of 20% will be $218.75
B. The discount of flat 20 % gives a bigger savings in cost for the customer.

Answer:
1.If you are to check the figure you will find that it is a rectangles. You should know the properties of a rectangle.
we are goin to use the property: Each vertex of a rectangle has angle equal to 90 degreesmeaning since m∠SUT and m∠ RUS form the vertex when added they give 90°3x+6+(5x-4)=90°
3x+5x+6°-4°=90°
8x+2°=90°

An isolated agricultural country has two distinct regions: a lowland plain and an upland of rugged hills. On one unit of land on the PLAIN, a farmer can raise 10 bushels of grain or graze 10 sheep. On one unit of land in the HILLS, a farmer can raise 2 bushels of grain or graze 4 sheep.
Determine which region has the absolute advantage for sheep production. Explain your answer.
Hills region has the advantage for sheep production because when a farmer raised 2 bushels of grain, then gaze 4 sheep.
The most popular animal fiber is sheep's wool, which is often gathered by shearing. In Commonwealth nations, ovine meat is referred to as lamb when it comes from younger animals and mutton when it comes from older ones; in the United States, meat from both older and younger animals is often referred to as a lamb.
Today, sheep are still farmed for their meat and wool, as well as on occasion for their pelts, as dairy animals, or as scientific model organisms. Most of the world's populated areas engage in sheep farming, which has been a foundational activity for several civilizations.

Step-by-step explanation:
ABCD is a rectangle.
so, it has 2 pairs of equal and parallel sides.
all 4 angles are 90°.
both diagonals are equally long and intersect each other at their midpoint. so, all 4 half-diagonal segments are equally long.
(1)
2x + 4y = 4x - y = 36/2 = 18 cm
we can split this into 2 equations
2x + 4y = 4x - y
5y = 2x
x = 5y/2
and e.g.
4x - y = 18
now we use the first equation in the second
4(5y/2) - y = 18
20y/2 - y = 18
10y - y = 18
9y = 18
y = 2
x = 5y/2 = 5×2/2 = 5
(2)
I cannot draw here, but the shortest distance between a point and a line is always a height (a line segment from the point meeting it intersecting the line at a right angle, 90°).
(3)
e.g.
AE, AD/2 and the drawn height from E to AD create a right-angled triangle.
we know AD/2 = 15 cm
from (1) we know AE = 4x - y = 4×5 - 2 = 20 - 2 = 18 cm.
the height E to AD we get via Pythagoras
AE² = (AD/2)² + height²
height² = AE² - (AD/2)² = 18² - 15² = 324 - 225 = 99
height = sqrt(99) = sqrt(9×11) = 3×sqrt(11)
remember trigonometry ?
this height = sin(theta) × AE
sin(theta) = height / AE = 3×sqrt(11) / 18 = sqrt(11)/6 =
= 0.552770798...
theta = 33.55730976...° ≈ 34°
(4)
the diagonals of a square bisect the angles of the square, so that theta would become 90/2 = 45°.

if a ball is thrown into the air with a velocity of 20 ft/second it's height in feet and seconds is given by f(t) = 20t - 10t^2. find average velocity for the time period t0 = 1 to t=2
The average velocity is -10 ft/s.
What is Average velocity?Average velocity is just the average speed with a direction. If a trip starts and ends at the same point, the total displacement is zero, so the average velocity is zero.
For example, someone who takes 40 minutes to drive 20 miles north and then 20 miles south (to end up at the same place), has an average speed of 40 miles divided by 40 minutes, or 1 mile per minute (60 mph).
Given:
f(t) = 20t - 10t²
Now, from t=1 to t=2
f(1)= 20*1 - 10 * 1*1
f(1)= 10
and, f(2)=20*2-10*2*2
f(2)= 40-40
f(2)=0
Now,
Average velocity:
v = ( 0-10 ) / ( 2- 1 )
= -10 ft/s
hence, the average velocity is -10 ft/s.

According to the solving the Hight in feet at 2 second is 74.
What is the link between height and time, as well as height and velocity?This asserts that the height (h) of a projectile is equal to the combination of two products: its initial velocity and time in the air, and indeed the acceleration constant as well as half of the time squared.
What is the Max height formula?max = h plus V02 / (4 * g) When launching from the ground, the range is maximized (h = 0). If = 0°, therefore vertical velocity becomes equal to zero (Vy = 0), indicating horizontal projectile motion.
According to the given data:Given h(t)=−16t²+69t
t = 2 sec
substituting the value of t = 2.
h(2)=−16(2)²+69(2).

An accounting machine operator wanted to divide a 65 minute job between two identical machines so that one machine would take one and a half times as long as the other. How much time was taken by the machine doing the longer job?
The slow machine did the job is 39 minutes as calculated with the help of a linear equation in one variable.
A linear equation in one variable is given by the combination of the variable with constants and coefficients such that a unique relationship is established between the terms.
Let us consider the faster machine takes x minutes the finish the job.
Hence the slower machine will take one and a half times .
∴ slower machine takes 1.5 x minutes.
Total time taken by the two machines = x + 1.5x = 2.5 x
But together the two machines will take 65 minutes to complete the job .
So now we form a linear equation with the variable x to solve for the value of x
∴ 2.5 x = 65
or, x = 65 ÷ 2.5
or, x = 26 minutes
Therefore the faster machine takes 26 minutes.
Hence the slower machine will take 1.5 x = 1.5 × 26 = 39 minutes.
