Step-by-step explanation:
Does the MVT apply? Explain why or why not.
y=-x^2/x-1 ; [-1,1]
Hi there!
[tex]\large\boxed{\text{No, it does not.}}[/tex]
[tex]y = \frac{x^{2} }{x-1}[/tex]
Looking at the equation, we can see that there is a discontinuity at x = 1 (Vertical Asymptote).
The interval given also includes x = 1 as an enclosed value.
Therefore, the MVT does not apply because the equation is not continuous on the interval [-1, 1].

Step-by-step explanation:
Step 1: Define Equation
1/2x + 4 = 6
Step 2: Solve for x
Subtract 4 on both sides: 1/2x = 2Divide 1/2 on both sides: x = 4Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 1/2(4) + 4 = 6Multiply: 2 + 4 = 6Add: 6 = 6Here we see that 6 does indeed equal 6.
∴ x = 4 is the solution to the equation.

Answer:
D) 41.81 degrees
Step-by-step explanation:
In this problem, we are given a leg length (a=12) and the hypotenuse (c=18).
We need to select which trigonometric identity to use with the acronym SOHCAHTOA:
SOH -> sine=opposite/hypotenuse
CAH -> cosine=adjacent/hypotenuse
TOA -> tangent=opposite/adjacent
Given side a is opposite of angle A and side c is the hypotenuse, we clearly need to use the sine function.
Set up an equation based on the information you have:
sin(A)=12/18
Now take the inverse:
sin^-1(sin(A))=sin^-1(12/18)
A=41.8103149
So the best option is answer D) 41.81 degrees

the variable y varies directly as x. when x=20, y=12. what is the value of y when x=15?
Answer:
9
Step-by-step explanation:
The value of y at x =15 is 9.
What is Direct Variation?Two variables are said to be in Direct Variation when increasing one variable the other also increases.
The direct variation is represented by
y ∝ x
y = kx
where k is the proportionality constant
the value of y =12 , x = 20
12 = k * 20
12/20 = k
k = 0.6
The equation becomes
y = 0.6 x
The value of y at x = 15 is
y = 0.6 * 15
y =9
Therefore, the value of y at x =15 is 9.

Sakura's house is at an elevation between 113 m and 120 m above sea level. Her friend Ted lives about 15 m below her. Choose the compound inequality that describes the elevation x of Ted's house. Part B Ted lives between _____m and _______m above sea level.
The compound inequality to describe the elevation of Ted's house is 135 > x > 128.
Ted lives between 128m and 135m above sea level.
How to explain the inequality?Now it is given that,
Sakura's house is at an elevation between 113 m and 120 m above sea level.
Let x be the elevation of Sakura's house.
So, 120 > x > 113
Now Ted lives about 15 m below her
Ted's house elevation = x - 15
So, the compound inequality to describe the elevation of Ted's house,
120 > x - 15 > 113
Adding 15 to the inequality we get,
120 + 15 > x - 15 + 15 > 113 + 15
Solving we get,
135 > x > 128
This is the required compound inequality.
Thus, the compound inequality to describe the elevation of Ted's house is 135 > x > 128.

Find the average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4].
The average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4] is 111.
According to the given question.
We have a function g(x) = 7x^2 + 8x^3.
And a interval [-3, 4].
As we know that, the average rate of change of y over an interval between 2 points (a, f(a)) and (b, f(b)) is the slope of the secant line connecting the 2 points.
To calculate the average rate of change between the 2 points we use the formula
f(b) - f(a)/ b - a
Therefore, the average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4] is given by
[7(4)^2 + 8(4)^3 - 7(-3)^(2) - 8(-3)^3]/4 + 3
= [112 + 512 - 63 + 216]/7
= 777/7
= 111
Hence, the average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4] is 111.

The price of fuel may increase due to demand and decrease due to overproduction. Marco is studying the change in the price of two types of fuel, A and B, over time.
The price f(x), in dollars, of fuel A after x months is represented by the function below:
f(x) = 2.27(0.88)x
Part A: Is the price of fuel A increasing or decreasing and by what percentage per month? Justify your answer. (5 points)
Part B: The table below shows the price g(m), in dollars, of fuel B after m months:
m (number of months) 1 2 3 4
g(m) (price in dollars)3.44 3.30 3.17 3.04
Which type of fuel recorded a greater percentage change in price over the previous month? Justify your answer.
Answer:
A. decreasing 12% per month
B. fuel A recorded the greater change
Step-by-step explanation:
Given an equation and a table of values, you want to compare the rates of change each represents.
A.The fuel price is described by ...
f(x) = 2.27(0.88^x)
We recognize this exponential equation to be of the form ...
f(x) = (initial value) × (growth factor)^x
Comparing parts of the equation, we see ...
growth factor = 0.88
The relation between growth factor and growth rate is ...
growth factor = 1 + growth rate
growth rate = growth factor - 1 = 0.88 -1 = -0.12 = -12%
This tells us the rate of change in fuel price is -12% per month.
B.To find the percentage change, we can use the formula ...
percent change = ((new value) / (old value) -1) × 100%
Applied to the first two table values, we have ...
percent change = (3.30/3.44 -1) × 100% ≈ -4.07%
This decrease of 4.07% is less than the decrease of 12% represented by the equation. Type A fuel recorded the greater percentage change.
