The constant of proportionality is 0.2
The constant of proportionality for Josiah's speed is 0.2 miles per minute.
To find the constant of proportionality, we can use the formula:
constant of proportionality = distance / time
In this case, we have the distance Josiah skateboards from his house to school is 4 miles, and it takes him 20 minutes.
So, the constant of proportionality is:
4 miles / 20 minutes = 0.2 miles/minute
Therefore, the constant of proportionality for Josiah's speed is 0.2 miles per minute. This means that he skateboards at a constant rate of 0.2 miles per minute from his house to school.

evaluate the piecewise function
Answer:
f(-3)=-1
f(4)=7
f(-1)=-3
f(12) = -24
Step-by-step explanation:
Piecewise Functions
The piecewise functions define different pieces or subfunctions where the domain is divided into parts according to some conditions on the independent variable.
The pieces of the function are defined as shown below:
[tex]f(x)=\left\{\begin{matrix}-1 &x\le -2\\ 2x-1 &-2<x\le 4 \\ -3x+8 &x>4 \end{matrix}\right.[/tex]
Let's find the values of:
f(-3). Here the variable x is -3. We have to find the interval where x=-3 belongs. Since -3 ≤ -2:
f(-3)=-1
f(4). The variable x is 4 and it belongs to the second interval, thus
f(4)=2*4-1=7
f(4)=7
f(-1). x = -1. It belongs to the second interval, thus:
f(-1)=2*(-1)-1=-3
f(-1)=-3
f(12). x=12 belongs to the last interval since 12 > 4, thus:
f(12)= -3*12+8 = -36 + 8 = -24
f(12) = -24
Derek collects quarters that have the names of the 50 U.S. States on them. He has collected 13 different state quarters in 2.25 months. His grandfather is coming to visit him in 9 months, and he wants to show his grandfather his collection. If he continues collecting quarters at the same rate, will his collection be complete by the time his grandfather visits? Explain your answer.
Answer:
Yes, his collection will be complete by the time his grandfather visits
Step-by-step explanation:
Here, we want to know if his collection would be complete by the time his grandfather visits.
From the question;
he has collected 13 different quarters in 2.25 months
At the same rate, x different quarters will be collected in 9 months
Thus, mathematically;
x * 2.25 = 13 * 9
x = (13 * 9)/2.25 = 52
Thus, at this rate he would have collected 52 quarters in 9 months.
Since he has only 50 to collect, it means his collection would be complete by the time his grandfather visits

Yosai is making a kimono for her father, The belt for the kimono should be one hundred sixty-three centimeters long. She has two meters of fabric. How much fabric will she have left after making the belt? (State your answer in meters.)
Answer
.37 meters
Step-by-step explanation:
Convert 2 meters to 200 centimenters (1m = 100cm)
200cm - 163cm = 37cm
Convert 37cm to meters
37cm = .37 meters
Which function inputs will result in a horizontal stretch of the function f(x) = x? Check all that apply. F f(StartFraction 3 Over two EndFraction x) f(x + 2) f f(StartFraction one-half EndFraction x) f(x – 3.2) f(x) f f(StartFraction 2 Over 3 EndFraction x)
Answer:
The correct options are;
3) f(1/2·x)
5) f(2/3·x)
Step-by-step explanation:
The given parameter is presented here as follows;
f(x) = x
Therefore;
f(x) = y = x
Comparing with the general equation for a straight line, y = m·x + c, we have;
For y = x, m = 1
∴ The slope = 1
1) For f(3/2·x) = y = 3/2·x, the slope, m = 3/2 which is a steeper slope than m=1 and therefore a has more increase in y than in x values or has a vertical stretch rather than a horizontal stretch
2) For f(x + 2) = y = x + 2, the slope, m = 1 which gives an equal slope of m = 1 to the slope in the question, f(x) = x, resulting in no change in stretch
3) For f(1/2·x) = y = 1/2·x, the slope, m = 1/2 which is a gentler slope slope than m=1 as y increase half unit, for each unit increase in x and the function is horizontally stretched
4) For f(x - 3/2) = y = x - 3/2, the slope, m = 1 which gives an equal slope of m = 1 to the slope in the question, f(x) = x, resulting in no change in stretch
5) For f(2/3·x) = y = 2/3·x, the slope, m = 2/3 which is a gentler slope slope than m = 1 as y increase 2/3 unit, for each unit increase in x and the function is horizontally stretched.

Find the value of r so the line that passes through each pair of points has the given slope.
(5, 9), (r, –3), m = –4
The value of r is 8 for the points to have a slope of -4.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope of the line is also defined as the ratio of the rise and the run.
The slope is calculated by the formula below,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the points are (5, 9) and (r, –3) and the slope is -4. The value of the unknown number will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
-4 = ( -3 - 9) / ( r - 5 )
-4r + 20 = -12
-4r = -32
r = 32 / 4
r = 8
Therefore, the value of r is 8 for the points to have a slope of -4.
