At the end of a snow storm, Gavin saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. There was a depth of 10 inches of snow on the lawn when the storm ended and then it started melting at a rate of 0.5 inches per hour. Make a table of values and then write an equation for S,S, in terms of t,t, representing the depth of snow on Gavin's lawn, in inches, tt hours after the snow stopped falling.
Answers
Answer:
s (t) = 12 - 0.75t
Step-by-step explanation:
Given: The snow started melting at a rate of 0.75 inches per hour and it is known that 4 hours after the storm ended, after the storm ended, the depth of snow was down to 9 inches.
Snow melted in 4 hours =
Initial depth of snow = 9 + 3 inches = 12 inches.
Now, depth of snow on Tristan's lawn = Initial depth -0.75(Number of hours)
Let S(t) be the depth of snow on Tristan's lawn, in inches, t hours after the snow stopped falling.

Answers
Answer:
a.) 10 months
b.) Kool Karate
c.) Karate Klub
Step-by-step explanation:
Karate Klub : y=25x+200
Kool Karate : y=35x+100
A.) First, set the equations equal to each other then solve for x. [tex]A.) 25x+200=35x+100\\\\[/tex]
take away 100 from both sides
[tex]25x+100=35x[/tex]
take away 25x from both sides
[tex]100=10x[/tex]
divide 10 from both sides so x can be by itself and equal to 1
[tex]10=x[/tex]
This means that at 10 months, the cost is the same for both.
B.) Substitute 6 for x in both equations
Karate Klub : [tex]y=25(6)+200\\y=350[/tex]
Kool Karate :[tex]y=35(6)+100\\y=310[/tex]
The cost for Kool Karate is cheaper, so that is what he should join.
C.) Substitute 12 for x in both equations.
x=12 because there are 12 months in a year.
Karate Klub:[tex]y= 25(12)+200\\y=500[/tex]
Kool Karate:[tex]y=35(12)+100\\y=520[/tex]
The cost for Karate Klub is cheaper, so that is what he should join.

Answers
Using the binomial distribution, it is found that about 75 batteries each day are defective.
For each battery, there are only two possible outcomes, either it is defective, or it is not. The probability of a battery being defective is independent of any other battery, hence the binomial distribution is used to solve this question.
What is the binomial probability distribution?It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
In this problem:
3 out of 20 batteries are defective, hence p = 3/20 = 0.15.Each day, 500 batteries are produced, hence n = 500.Then:
[tex]E(X) = np = 500(0.15) = 75[/tex]
About 75 batteries each day are defective.

Part B: Test the solution(s) found in Part A using substitution. Identify each solution as either valid or extraneous.
Part C: Explain how the solution(s) of the equation 1/2x +2 = 1 / x^2 - 1 can be tested using a graph.
Answers
Answer:
x= 3
Step-by-step explanation: I'll assume the problems is
Cross multiply to get:
x2 - 1 = 2x + 2
x2 - 2x - 3 = 0
(x - 3)(x + 1) = 0
x = 3 and x = -1
Test (x = 3):
1/(2•3+2) = 1/(32 - 1)
1/8 = 1/8 true, so x = 3 is a valid solution
Test (for x = -1):
1/(2•(-1)+2) = 1/((-1)2 - 1)
1/0 = 1/0 not true since division by zero is undefined so x = -1 is not a solution (aka, it is extraneous).
To find solutions via graphing, graph y = 1/(2x + 2) and graph y = (x2 - 1) and find the points of intersection. Doing so confirms that the only solution is x = 3.

What most likely will happen if the pie maker bakes a seventh pie? The marginal cost will most likely decrease to $1. 00 The marginal cost will most likely increase to $2. 00 The marginal revenue will most likely decrease to $8. 0. The marginal revenue will most likely increase to $12. 0.
Answers
The marginal cost will most likely increase to $2.00
What is the marginal cost?Marginal cost is the change in the production costs that would be required to make one extra unit of production.
The marginal costs will continue to rise, increasing the total cost, while the marginal revenue remains the same, decreasing the profit.
For example, if a company produces a cup for $5, and 10 cups would be $50, therefore, the marginal cost is the extra cost it would take to manufacture an additional cup.
Hence, the marginal cost will most likely increase to $2.00

Step-by-step explanation:
Concept:
We will start by explaining each option one after the other
Step 1:
The sum of two odd numbers
Let the first odd number be
[tex]2a+1[/tex]
Let the second odd number be
[tex]2B+1[/tex]
By adding the two numbers, we will have
[tex]2a+1+2B+1=2(a+B)+2[/tex]
Hence,
The sum of two odd numbers is even
Step 2:
The difference of two odd number
Let the first odd number be
[tex]2a+1[/tex]
Let the second odd number be
[tex]2B+1[/tex]
To find their difference, we will have
[tex]2a+1-(2B+1)=2a+1-2B-1[/tex]
[tex]=2a-2B[/tex]
Hence,
The difference between two odd numbers is even
Step 3:
Let the first even number be
[tex]2a[/tex]
Let the second odd number be
[tex]2B+1[/tex]
By adding the two numbers, we will have
[tex]2a+2B+1[/tex]
Hence,
The sum of an odd number and an even number is odd
Step 4:
The difference between an odd number and an even number
Let the first even number be
[tex]2a[/tex]
Let the second odd number be
[tex]2B+1[/tex]
Hence,
The difference will be
[tex]2a-(2B+1)[/tex]
[tex]2a-2B-1[/tex]
Hence,
The difference between an odd number and an even number is odd

- When graphing, if it is only less/greater than (< or >) the dot will be open
- When graphing, if it is less/greater than and equal too (≤ or ≥) the dot will be closed
- Then, if the x value is on the left side, the arrow will go in the direction of the inequality sign

x ≤ 9
[4] Divide both sides by -0.4, flip the sign, and then I flipped the equation to make it easy to graph
