The figure shows parallelogram PQRS on a coordinate plane. Diagonals SQ and PR intersect at point T. P(2b, 2c) Q(?, ?) T S(0, 0) R(2a, 0) Part A Find the coordinates of point Q in terms of a, b, and c.
The coordinates of point Q is the location of point Q in the parallelogram
The coordinates of point Q is (2b + 2a,2c)
How to determine the coordinates of Q?The coordinates are given as:
P(2b, 2c) Q(?, ?) S(0, 0) R(2a, 0)
Since the shape is a parallelogram; it means that the distance PQ is the same as the distance RS.
The distance RS is calculated as:
RS = (2a - 0, 0 - 0)
This gives
RS = (2a, 0)
The coordinates of Q is then calculated using:
Q = P + RS
This gives
Q = (2b,2c) + (2a,0)
Evaluate the sum
Q = (2b + 2a,2c)
Hence, the coordinates of point Q is (2b + 2a,2c)

The sinusoidal function that is modeled in the graph presented in this question is the expression y = 5 + 3 · sin [π · (x+2)/4], where x and y are the independent and dependent variable, respectively.
How to model a sinusoidal functionIn this question we must analyze periodic functions to determine the most appropriate model that best fit with the graph, the determination of the model will determine the inherent characteristics of the model. The graph seem to be a sinusoidal function.
Sinusoidal functions are bounded functions characterized by use of trigonometric expressions and the presence a lower and a upper bound, a period and phase. The entire formula is described below:
y = r + 0.5*(M-m) · sin [2π · (x-F)/T] (1)
Where:
r - Middle valuem - Lower boundM - Upper boundF - Phasex - Independent valuey - Dependent valueT - PeriodThe period is the time in which a sinusoidal function completes a cycle and the phase is a horizontal translation applied to a canonical sinusoidal function.

Step-by-step explanation:
Chris and Sam earn money shoveling snow, as described below. The amount of money Chris earns can be modeled by the equation y=8.25x, where the y is the total amount of money, in dollars, earned in x hours. The table below shows the relationship between the total amount of money earned,y, in dollars, and the total amount on time worked, x, in hours, for Sam.
Based on the data given on the amounts Chris and Sam are paid, we can infer that Chris earns $0.75 more per hour than Sam.
How much do Chris and Sam earn?Chris earns $8.25 an hour according to the equation that shows how he is paid of y = 8.25x.
The amount earned by Sam can be found as:
= Any value of y / Corresponding value of x
= 30 / 4
= $7.50 per hour.
The difference between their pay is:
= 8.25 - 7.50
= $0.75

You are collecting data to find out what the most popular lunch choice is. Each lunch period, you ask 15 students who buy lunch. There are 4 lunch periods a day. 25 students choose pizza. If there are about 600 students who buy lunch each day, about how many can you predict will buy pizza?
Answer:
250
Step-by-step explanation:
1. Find the total amount of people interviewed
You asked 15 students over 4 periods of lunch. That means you have to multiply:
15 x 4 = 60. You asked 60 people total.
2. Solve
You know that 25 people chose pizza out of the 60 people that you interviewed. That would make a fraction: 25/60
Now, there are 600 people, and the question is asking you how many people will get pizza based on the ratio of 25/60
So, in this case, 25/60 = x/600
You have to multiply 60 by 10 to get 600 as your denominator.
So, similarly, you have to multiply 25 by 10 to keep the same ratio.
25 x 10 = 250
Hence, 250/600 people will buy pizza.

in the graph?
A. y=1/5x
B. y=5x
C.y=-5x
D. y=2/5x
Answer:
B.) y = 5x
Step-by-step explanation:
The point-slope test (y₁ - y₂ = m(x₁ - x₂)) can be used to determine the slope of a line. The hypotenuse of a right triangle is the diagonal line, opposite of the right angle. The slope (m) is found using two points on the line.
First point: (1,5) Second Point: (-2,-10)
y₁ - y₂ = m(x₁ - x₂) -----> (y₁ - y₂) / (x₁ - x₂) = m
(5 - (-10)) / (1 - (-2)) = m
(15) / (3) = m
5 = m
The slope-intercept equation (y = mx + b) can be used to determine the y-intercept. The y-intercept is the "y" value when "x" is zero. In the equation, the y-intercept value is represented by "b". This variable can be found using the value of the slope and a point on the line.
Point: (-2,-10) Slope: 5
mx + b = y
5(-2) + b = -10
-10 + b = -10
0 = b
After plugging in the values to the standard form equation, you are left with y = 5x. When "x" increases by one, the "y" value increases by five

a. What is asked? How long will it take to cover 330 miles travelling at a speed 50% greater than 40 mph
b. What are the given facts?
Current Speed = 40 mph
New Speed = 40 mph + 50% of 40 mph

Distance = Speed x Time
330 miles = (60 mph)*(Time)
Time = (330 miles)/(60 miles/hour)
Time = 5.5 hours
4. Check
Distance = Speed x Time

Answer:5,200ft and 145in is less than a mile and 40in
Step-by-step explanation: I got this answer by first figuring out how many feet are in 145in so i did 145 divided by 12 which gave me 12.083... so I added just 12 to 5,200 which gives 5,212
Then I know that there are 5,280ft in 1 mile which is already bigger than 5,212 then I still add 40 divided by 12 which equals 3.3... to the total which gives me 5,283ft which is more than 5,212
