A coat check service charges $2 for the first hour and $1 for each addition hour or fraction of an hour. Which point is not included in the graph of this step function.
A: (2.5,3)
B: (2.0, 3)
C: (3.0, 4)
D: (3.5, 5)
The points not included in the graph are A: (2.5,3), B: (2.0, 3), C: (3.0, 4) and D: (3.5, 5)
How to determine the point is not included in the graphFrom the question, we have the following parameters that can be used in our computation:
Initial service charge = $2
Additional charges = $1 per hour
This means that the charges after x hours is
f(x) = Initial service charge + Additional charges * x
Substitute the known values in the above equation, so, we have the following representation
f(x) = 2 + x
Using the given points, we have
f(2.5) = 2 + 2.5 = 4.25
f(2.0) = 2 + 2.0 = 4.0
f(3.0) = 2 + 3.0 = 5.0
f(3.5) = 2 + 3.5 = 5.5
This means that all of the points are not in the graph

When converted to a household measurement, 9 kilograms is approximately equal to a) 9000 grams. b) 9000 ounces. 19.8 ounces. d) 19.8 pounds.
Answer:
9000 grams
Step-by-step explanation:
1 kilogram = 1000grams
9 kilograms = 9000 grams
Answer: d) 19.8 pounds
Step-by-step explanation: (1000)(9 kilograms) = 9000 grams. And yes 9 kilograms does equal to 9000 grams but that isn't the correct answer. Also kilograms isn't equal to b) 9000 ounces, and c) 19.8 ounces even though ounces are apart of the household measurement system because 9 kilograms is equal to 317.466 ounces. (35.274)(9 kilograms) = 317.466 ounces. So the obviously only correct answer is d) 19.8 pounds because 9 kilograms is equal to 19.8 pounds. (2.205)(9 kilograms) = 19.8416 pounds.

Answer:
MN = 56
Step-by-step explanation:
This can only be solved if we know the relation of MN to other dimensions of the trapezoid. If we assume MN is a midline (AM=MD, BN=NC), then MN is the average of the base lengths:
MN = (AB +CD)/2
2MN = AB +CD . . . . . multiply by 2

What is the slope of the line that passes
through the points (8,5) and (4, -9)?
Step-by-step explanation:
Find slope
m = (y2 - y1)/(x2 - x1)
m = (-9 - 5)/(4 - 8)
m = -14/-4
m = 7/2
Slope → 7/2
A farmer has collected data from one of his crops. Suppose the farmer found that the number of seeds, () (in weeks) was
()= t^2/4 seeds per mature plant.
Further, the farmer discovered that only
()=40.56−^2/4+1801.75/^2+188.8/
plants matured to age .
Determine the maximum rate of change of the crop's seed production
The rate of change of the crop's seed production is given by differential of
the function of the number of seeds produced.
The maximum rate of change of the seed production is approximately 117 seeds per week.Reasons:
[tex]\displaystyle \mathrm{The \ number \ of \ seeds \ per \ plant, \ S(t)}= \mathbf{\frac{t^2}{4}}[/tex]
[tex]\displaystyle \mathrm{Plants \ that \ mature \ to \ age \ t, \ P(t)}= \mathbf{40.56- \frac{t^2}{4} + \frac{1,801.75}{t^2} +\frac{188.8}{t}}[/tex]
The number of seeds produced by all the plants, n = S(t) × P(t)
Which gives;
[tex]\displaystyle \mathrm{\ P(t) \times S(t)}= \left(40.56- \frac{t^2}{4} + \frac{1,801.75}{t^2} +\frac{188.8}{t}\right) \times \frac{t^2}{4}[/tex]
[tex]\displaystyle \mathrm{ \left(40.56- \frac{t^2}{4} + \frac{1801.75}{t^2} +\frac{188.8}{t}\right) \cdot\frac{t^2}{4}} = \mathbf{-0.0625\cdot t^4+10.14\cdot t^2 + 47.2 \cdot t + 450.4375}[/tex]
The maximum rate of change is the highest value of the rate of change function.
To find the maximum rate of change of the crops production, the above
function for the number of seeds is differentiated twice. The first
differentiation is to find the rate of change function, and the second
differentiation is to determine the value of t at the maximum rate of change
as follows;
The rate of change of the crop's seed production is given by following function;
[tex]\displaystyle \frac{d}{dt} \left( -0.0625\cdot t^4+10.14\cdot t^2 + 47.2 \cdot t + 450.4375 \right) = -0.25\cdot t^3+ 20.28 \cdot t - 47.2[/tex]
Rate of change function, n'(t) = -0.25·t³ + 20.28·t + 47.2
At the maximum value of the above rate of change function, we have
[tex]\displaystyle \frac{d}{dt} \left( -0.25\cdot t^3+ 20.28 \cdot t - 47.2 \right) = \mathbf{-0.75 \cdot t^2 + 20.28} = 0[/tex]
Which gives
[tex]\displaystyle t^2 = \frac{20.28}{0.75} = \mathbf{27.04}[/tex]
t = √27.04 = 5.2
At the maximum rate of change, the number of weeks, t = 5.2
Plugging in the value of t = 5.2 into the rate of change function gives;
n'(5.2) = -0.25·5.2³ + 20.28·5.2 + 47.2 = 117.504
The maximum rate of change of the crop's seed production is approximately 117 seeds per week.Learn more here:

Write the equation for the line that goes through ( 10, - 12 ) with slope m= - 4
Answer:
The equation of a line is written in the form y=mx+b. “m” is the slope and “b” is the y-intercept. With the given slope, the equation so far is y=-4x+b. To find the value of b, substitute the given point.
-12=-4(10)+b
-12=-40+b
28=b

The sum of the squares of two numbers is 8 . The product of the two numbers is 4 . Find the numbers.
Hello there.
First, assume the numbers [tex]x,~y[/tex] such that they satisties both affirmations:
The sum of the squares of two numbers is [tex]8[/tex].The product of the two numbers is [tex]4[/tex].With these informations, we can set the following equations:
[tex]\begin{center}\align x^2+y^2=8\\ x\cdot y=4\\\end{center}[/tex]
Multiply both sides of the second equation by a factor of [tex]2[/tex]:
[tex]2\cdot x\cdot y = 2\cdot 4\\\\\\ 2xy=8~~~~~(2)^{\ast}[/tex]
Make [tex](1)-(2)^{\ast}[/tex]
[tex]x^2+y^2-2xy=8-8\\\\\\ x^2-2xy+y^2=0[/tex]
We can rewrite the expression on the left hand side using the binomial expansion in reverse: [tex](a-b)^2=a^2-2ab+b^2[/tex], such that:
[tex](x-y)^2=0[/tex]
The square of a number is equal to [tex]0[/tex] if and only if such number is equal to [tex]0[/tex], thus:
[tex]x-y=0\\\\\\ x=y~~~~~~(3)[/tex]
Substituting that information from [tex](3)[/tex] in [tex](2)[/tex], we get:
[tex]x\cdot x = 4\\\\\\ x^2=4[/tex]
Calculate the square root on both sides of the equation:
[tex]\sqrt{x^2}=\sqrt{4}\\\\\\ |x|=2\\\\\\ x=\pm~2[/tex]
Once again with the information in [tex](3)[/tex], we have that:
[tex]y=\pm~2[/tex]
The set of solutions of that satisfies both affirmations is:
[tex]S=\{(x,~y)\in\mathbb{R}^2~|~(x,~y)=(-2,\,-2),~(2,~2)\}[/tex]
This is the set we were looking for.
