Answer:
Evans would have $852.8
Step-by-step explanation:
Given
\(PV = \$800\)
\(r = 3.25\%\)
\(t = 2\)
\(n = 1\) --- annually'
Required
The future value
This is calculated using:
\(FV = PV*(1 + \frac{r}{n})^{nt\)
So, we have:
\(FV = 800 * (1 + 3.25\%/1)^{2*1}\)
\(FV = 800 * (1 + 3.25\%)^{2}\)
\(FV = 800 * (1 + 0.0325)^{2}\)
\(FV = 800 * (1 .0325)^2\)
\(FV = 852.845\)
\(FV = 852.8\)

The average rate of change of the function over the interval is -6
Finding the average rate of changeFrom the question, we have the following parameters that can be used in our computation:
The graph
The interval is given as
From x = 2 to x = 4
The function is a quadratic function
This means that it does not have a constant average rate of change
So, we have
f(2) = -3
f(4) = -15
Next, we have
Rate = (-15 + 3)/(4 - 2)
Evaluate
Rate = -6
Hence, the rate is -6

The properties that we can use in order to solve this equation are:
- Reflexive
- Addition
- Subtraction
- Multiplication
- Division
- Distributive
From S1 to S2, the property we applied is the R1 = Subtraction property of equality, because both sides of the equation were subtracted by 32.
From S2 to S3, the property we applied is the R2 = Distributive property of equality, because we expanded the product of 9 by the term (x - 2).
From S3 to S4, we can divide both sides by 9, so we will be using R3 = Division property of equality, and the result would be S4 = x - 2 = 43/9
Then, from S4 to S5, using the addition property of the equality, we added 2 to both sides of the equation, so the result is x = 61/9.
For R5, we can write the Reflexive property of equality, because we are just stating the value of x
For the following exercises, consider the function f(x) = (1+x)^1/x. Round all answers to five decimal places. Evaluate f(-0.01).
The value of f(-0.01) is approximately 0.99005.
To evaluate f(-0.01), we substitute -0.01 into the function f(x) = (1+x)^(1/x). Thus, we have f(-0.01) = (1+(-0.01))^(1/(-0.01)).
Using a calculator, we simplify this expression to f(-0.01) = 0.99005. Therefore, the value of f(-0.01) rounded to five decimal places is approximately 0.99005.
The function f(x) = (1+x)^(1/x) represents an exponential function with a variable exponent. In this case, we are evaluating the function at x = -0.01.
By substituting this value into the function and performing the necessary calculations, we find that f(-0.01) is approximately 0.99005. This means that when x is equal to -0.01, the function value is approximately 0.99005.

c. In an algebraic expression each term can only be combined with another like term. For example x terms can be combined only with x terms, y terms can be combined only with y terms etc.
This is similar to the above example in which pizza(p) can only be combined with pizza(p), drinks (d) can only be combined with drinks(d) and cone(c) can only be combined with cone(c)
Step-by-step explanation:
a.
From the cute diagram we see that the family bought
2 pizzas + 2 drinks + 1 cone + 1 pizza + 1 cone + 2 pizzas + 1 drink
Using the variables provided, this becomes
2p + 2d + 1c + 1p + 1c + 2p + 1d
b.
Combining like terms the total purchase is:
(2p + 1p + 2p) + (2d + 1d) + (1c + 1c)
Adding the coefficients of each grouped term we get
(5p) + (3d) + (2c)
Opening the brackets, this becomes

Caleb was Blank blocks from home. He is walking home at a rate of Blank blocks per minute
First we are going to see if the relationship is proportional or not.
Let us calculate 2 ratios with two pairs to see if there is a constant of proportionality
10/1 = 10
8/2= 4
Since the ratios are not the same this relationship is not proportional.
From the information we can deduce that each minute the distance is reduced 2 blocks. Then, at the beginning Caleb was 12 blocks from home and he is walking at a rate of -2 blocks per minute.
- Since the relationship is not proportional we can not write an equation of the form y=k*x.

The solution set of f(x) > 0 is x ∈ (-2, 8).
What is the set of the function?
To find the solution set of f(x) > 0, we need to first determine the critical values of x where f(x) changes sign.
Let's start by finding the domain of the function:
x² - 6x - 16 ≠ 0
We can solve for x by using the quadratic formula:
x = [6 ± √(6² + 4(16))]/2 = [6 ± √52]/2 = 3 ± √13
So the domain of f(x) is (-∞, 3 - √13) U (3 + √13, ∞).
Now let's factor the numerator and denominator of f(x):
f(x) = (x + 10)/[(x - 8)(x + 2)]
The critical points occur where the numerator or denominator of f(x) changes sign.
The numerator changes sign at x = -10, and the denominator changes sign at x = -2 and x = 8.

Able is carving a rectangular pyramid clock out of green quartz. The length of the rectangle base is 14 cm and the height of the clock is 9cm. If the clock needs to have a volume of 168cm3 what is the width of the base
Answer:
14cm
Step-by-step explanation:
Volume of the pyramid = Base area × height/3
V = BH/3
Base area = 14×width
Height= 9cm
Volume = 168cm³
Substitute into the formula
168 = 4w×9/3
36w = 168×3
36w = 504
w = 14cm
Hence the width of the pyramid is 14cm
A research study investigated differences between male and female students. Based on the study results, we can assume the population mean and standard deviation for the gpa of male students are µ = 3. 5 and σ = 0. 5. Suppose a random sample of 100 male students is selected and the gpa for each student is calculated. What is the probability that the random sample of 100 male students has a mean gpa greater than 3. 42?
The probability that the random sample of 100 male students has a mean gpa greater than 3. 42 is 0.9452.
What is Standard deviation?A statistic known as the standard deviation is used to describe how volatile or dispersed a group of numerical values is. While a big standard deviation denotes that the values are scattered across a wider range, a low standard deviation indicates that the values tend to be close to the set mean.
From the given information, a scores random sample of 100 male students is selected and the GPA for each student is calculated which follows approximately normal with a mean of 3.5 and standard deviation of 0.5. That is,
µ = 3. 5 and σ = 0. 5
and the random sample of 100 male students has a mean GPA 3.42 is considered.
The z-score value is,
Z=( 3.42-3.5)/ (0.5/√100)
Z= -0.08/0.05
Z=-1.6
The value of z-score is obtained by taking the difference of x and µ. Then the resulting value is divided with the standard deviation by sample size.
The probability that the random sample of 100 male students has a mean GPA greater than 3.42 is obtained below:
The required probability is,
P(X>3.42)=P(z>-1.6)
= 1- P(Z≤-1.6)
From the “standard normal table”, the area to the left of Z=-1.6 is 0.0548.
P(X>3.42)= 1- P(Z≤-1.6)
=1-0.0548
=0.9452

The component form of the following vectors is Option A. V = (38.3, 32.1).
To find the component form of a vector given its magnitude and direction angle, we can use trigonometry.
The component form of a vector in two dimensions is represented as (x, y), where x is the horizontal component and y is the vertical component.
In this case, the magnitude of the vector is given as 50, and the direction angle θ is 50°. We can use this information to calculate the horizontal and vertical components.
The horizontal component (x) can be found using the formula x = magnitude * cos(θ), and the vertical component (y) can be found using y = magnitude * sin(θ).
Let's calculate the components:
x = 50 * cos(50°) ≈ 38.3
y = 50 * sin(50°) ≈ 32.1
Rounding the answers to the nearest tenth, we get the component form of the vector V as (38.3, 32.1).
Therefore, the correct answer is A. V = (38.3, 32.1).

Describe the graph of the function.
y =Square root of
x-1 + 4
Answer: The answer is D. the last option
Step-by-step explanation:
The correct answer is option d) The graph is the radical function, y = √x shifted right 1 unit and up 4 units.
The original function is y = √(x - 1) + 4, which represents a radical function.
This function involves taking the square root of the quantity (x - 1) and then adding 4 to the result.
By shifting the function right 1 unit, we are replacing x with (x - 1). This means that the graph will be shifted horizontally by 1 unit to the right compared to the standard square root function.
By shifting the function up 4 units, we are adding 4 to the output of the square root function.
This means that the graph will be shifted vertically by 4 units compared to the standard square root function.
Therefore, the graph of the function y = √(x - 1) + 4 is the radical function y = √x shifted right 1 unit and up 4 units.

Therefore
Critical Value
\(X=(\alpha,df_1)\)
\(X'=(\alpha,df_2)\)
Where
\(df=n-1\)
Therefore
\(X=(0.95,24)\)
\(X'=(0.95,15)\)
From Table
\(T_{Critical}=T_x,T_{x'}\)
\(T_{Critical}=0.41,2.701\)
Therefore
\(T_x<T<T_{x'}\)
Hence,We fail to reject the Null Hypothesis \(H_0\)
Option A , should not be rejected
