pls help!!! I will make you brainiest!!!!! what is the rate of change
Answer:
$2.69
Step-by-step explanation:
We can divide the cost in dollars to the gallons of gasoline to find the rate of change.
16.14 / 6 = $2.69
21.52 / 8 = $2.69
24.21 / 9 = $2.69
32.28 / 12 = $2.69
53.80 / 20 = $2.69
This means that each gallon costs $2.69, in other words this is the rate o change.

A junk drawer at home contains five pens, two of which work . What is the probability that you randomly grab two pens from the drawer and don’t end up with a pen that works? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.
Answer:
The probability is [tex]P(k) = \frac{4}{25}[/tex]
Step-by-step explanation:
From the question we are told that
The number of pens from the drawer is n = 5
The number of pens that doesn't work is k = 2
The probability that a does not work is
[tex]p = \frac{k}{n}[/tex]
=> [tex]p = \frac{2}{5}[/tex]
The probability that a pen works is
[tex]q = 1- p[/tex]
[tex]q = 1- \frac{2}{5}[/tex]
=> [tex]q = \frac{3}{5}[/tex]
Generally the probability that ending up with a pen that doesn't work is mathematically represented as
[tex]P(k) = p^2[/tex]
=> [tex]P(k) = [\frac{2}{5} ]^2[/tex]
=> [tex]P(k) = \frac{4}{25}[/tex]
The probability that you randomly grab two pens from the drawer and don’t end up with a pen that works is [tex]\dfrac{4}{25}[/tex].
Given information:
The number of pens in the drawer is [tex]n=5[/tex].
The number of pens that doesn't work is [tex]a=2[/tex].
So, the number of pens which works will be, [tex]b=5-2=3[/tex].
The probability of grabbing a pen that doesn't work will be,
[tex]P_a=\dfrac{2}{5}[/tex]
Now, two pens are grabbed randomly from the drawer. So, the probability that you randomly grab two pens from the drawer and don’t end up with a pen that works will be calculated as,
[tex]P=(P_a)^2\\P=\dfrac{2}{5}\times \dfrac{2}{5}\\P=\dfrac{4}{5}[/tex]
Therefore, the value of the required probability will be [tex]\dfrac{4}{5}[/tex].

Suppose the graph of a polynomial function P(x) has an x-intercept at (c,0) . Write 4-6 sentences analyzing whether (c,0) is also an x-intercept of the graphs that result from applying single transformations to P(x) . For each transformation, elaborate on whether (c,0) is always, sometimes, or never an x-intercept of the transformed graph, explaining your reasoning. For any transformations for which (c,0) is only sometimes an x-intercept of the transformed graph, design specific functions to illustrate how the other x-intercepts of the original graph determine whether (c,0) is an x-intercept of the transformed graph.

Solve this equation 5x–4=3x+18.
Answer:
Step-by-step explanation:
Step 1: Subtract 3x from both sides.
5x−4−3x=3x+18−3x
2x−4=18
Step 2: Add 4 to both sides.
2x−4+4=18+4

two angles are complementary. The larger angle is 6 more than five times the other. How large is the smaller angle?
Answer:
14 degrees
Step-by-step explanation:
Complementary angles means they add up to 90 degrees.
If the smaller angle times 5 plus 6 equals the bigger angle, then:
14 x 5 = 70
70 + 6 = 76
76 + 14 = 90
The measurements of the angles are 76 degrees and 14 degrees because the sum of the two complementary angles is up to 90 degrees.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called a "Angle."
Let x and y be the numbers:
From the definition of the complementary numbers:
x + y = 90
x = 6 + 5y
The above represents two linear equations in two variables solved by the substitution method:
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
6 + 5y + y = 90
6y = 90 - 6
6y = 84
y = 84/6
y = 14 degrees
The measure of the other angle x = 90 - 14 = 76 degrees
Thus, the measure of the angles is 76 degrees and 14 degrees because the sum of the two complementary angles is up to 90 degrees.

Bullco blends silicon and nitrogen to produce two types of fertilizers. Fertilizer 1 must be at least 40% nitrogen and sells for $70 per pound. Fertilizer 2 must be at least 70% silicon and sells for $40 per pound. Bullco can purchase up to 80 pounds of nitrogen at $15 per pound and up to 100 pounds of silicon at $10 per pound. Assuming all fertilizer products can be sold, formulate and solve an LP to help Bullco maximize profits.
Answer:
Maximize
z = 70(Xs1 + Xn1 ) + 40(Xs2 + Xn2 ) - 10 (Xs1 + Xs2 ) - 15(Xn1 + Xn2 )
Subject to the constraints
Xs1 + Xs2 ≤ 100
Xn1 + Xn2 ≤ 80
Xn1 ≥ 0.4 ( Xs1 + Xn1 )
Xs2 ≥ 0.7 ( Xs2 + Xn2 )
All Variables ≥ 0
Step-by-step explanation:
Firstly lets consider Xs1 and Xs2 to be the number of pounds of silicon used in fertilizer1 and fertilizer2 respectively
Also let Xn1 and Xn2 be the number of pounds of nitrogen used in fertilizer1 and fertilizer2 respectively
We know that the objective is to maximize the profits of Bullco.
z = [(Selling price of fertilizer1) (Amount of silicon and nitrogen used to produce fertilizer1) + (Selling price of fertilizer2) (Amount of silicon and nitrogen used to produce fertilizer2) - (Cost of silicon) (Amount of silicon used to produce fertilizer I and 2) - (Cost of nitrogen) (Amount of nitrogen used to produce fertilizer I and 2)]
so
z = 70(Xs1 + Xn1 ) + 40(Xs2 + Xn2 ) - 10 (Xs1 + Xs2 ) - 15(Xn1 + Xn2 )
Now
Constraint 1; At most, 100 lb of silicon can be purchased
Amount of silicon used to produce fertilizer 1 and 2 ≤ 100
Xs1 + Xs2 ≤ 100
Constraint 2; At most, 80 lb of nitrogen can be purchased
Amount of nitrogen used to produce fertilizer 1 and 2 ≤ 80
Xn1 + Xn2 ≤ 80
Constraint 3; Fertilizer 1 must be at least 40% of nitrogen
Amount of nitrogen used to produce fertilizer 1 ≥ 40% (fertilizer 1)
Xn1 ≥ 0.4 ( Xs1 + Xn1 )
Constraint 4; Fertilizer 2 must be at least 70% of silicon
Amount of silicon used to produce fertilizer 2 ≥ 70% (fertilizer 2)
Xs2 ≥ 0.7 ( Xs2 + Xn2 )
so the formulization of the given linear program is,
Maximize
z = 70(Xs1 + Xn1 ) + 40(Xs2 + Xn2 ) - 10 (Xs1 + Xs2 ) - 15(Xn1 + Xn2 )
Subject to the constraints
Xs1 + Xs2 ≤ 100
Xn1 + Xn2 ≤ 80
Xn1 ≥ 0.4 ( Xs1 + Xn1 )
Xs2 ≥ 0.7 ( Xs2 + Xn2 )
All Variables ≥ 0

Explain some methods of reducing friction between of matyer
Answer:
Step-by-step explanation:
1. Use of lubricants
Lubricants like oil and grease helps to decrease friction by forming a thin film in between different parts of the machine. This film covers up the scratches and bumps on the surfaces of different parts. This reduces interlocking between the two surfaces. Thus reducing the friction.
2. Use ball bearings
Two moving surfaces in a machine are attached by placing small steel balls or steel rollers in between them. This way, the moving parts avoid direct contact and the force of sliding friction turns into rolling friction. Rolling friction is less than sliding friction, in doing so reducing the friction.
3. Polishing
Polishing reduces the unevenness of a surface. This will reduce interlocking between the surfaces.
4. Streamlining
Streamlining is the process where you make a machine in a shape that avoids air and water resistance. This reduces friction because a streamlined object cuts through the water and air molecules.
