a. When a is large (graph b):
b. When a is small (graph c):
c. When a is negative (graph d):
See below for the changes when the exponential function is transformed
How to determine the effect of aThe exponential functions are given as:
[tex]y = \sqrt x[/tex]
[tex]y = 5\sqrt x[/tex]
[tex]y = 14\sqrt{x[/tex]
[tex]y = -2\sqrt{x[/tex]
An exponential function of the above form is represented as:
[tex]y = a\sqrt{x[/tex]
See attachment for the graph of the four functions.
When a is large
This is represented by [tex]y = 14\sqrt{x[/tex]
In this case, the curve of the base form [tex]y = \sqrt x[/tex] is vertically stretched and it moves closer to the y-axis
When a is small
This is represented by [tex]y = 5\sqrt x[/tex]
In this case, the curve of the base form [tex]y = \sqrt x[/tex] is vertically stretched and it moves away from the x-axis
When a is negative
This is represented by [tex]y = -2\sqrt{x[/tex]
In this case, the curve of the base form [tex]y = \sqrt x[/tex] is vertically stretched and is reflected across the y-axis.

The combinations of ordered triplets that are possible is equal to: A. 18.
How to find the possible number of ordered triplet?Since the common difference (d) between the consecutive terms in an arithmetic progression (AP) is constant, we have:
d = y - x = z - y
Rearranging the terms, we have:
x = y - d
z = y + d
From the given equation:
x + y + z = 30
y - d + y + y + d = 30
3y = 30
y = 30/3
y = 10.
So the arithmetic progression (AP) is given by:
(10 - d), 10, (10 + d)....
Since the common difference (d) is a natural number which would be from 1 to 9, the combinations of ordered triplets that are possible is as follows:
Number of possibilities = 9 × 2
Number of possibilities = 18.

The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $1,020,000, and it would cost another $22,000 to install it. The machine falls into the MACRS 3-year class, and it would be sold after 3 years for $599,000. The MACRS rates for the first three years are 0.3333, 0.4445, and 0.1481. The machine would require an increase in net working capital (inventory) of $19,500. The sprayer would not change revenues, but it is expected to save the firm $386,000 per year in before-tax operating costs, mainly labor. Campbell's marginal tax rate is 25%. (Ignore the half-year convention for the straight-line method.) Cash outflows, if any, should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to the nearest dollar. What is the Year-0 net cash flow? $ What are the net operating cash flows in Years 1, 2, and 3? Year 1: $ Year 2: $ Year 3: $ What is the additional Year-3 cash flow (i.e, the after-tax salvage and the return of working capital)? $ If the project's cost of capital is 11%, what is the NPV of the project? $ Should the machine be purchased? -Select-
1. The Year-0 net cash flow is -$1,061,500.
2. The net operating cash flows in Years 1, 2, and 3 are as follows:
Year 1: $288,750 ($386,000 x 1 - 0.25)
Year 2: $288,750 ($386,000 x 1 - 0.25)
Year 3: $288,750 ($386,000 x 1 - 0.25)
3. The additional Year-3 cash flow (i.e, the after-tax salvage and the return of working capital) is $468,750 {($599,000 x 1 - 0.25) + $19,500}.
4. The NPV of the project is ($13,139).
5. The machine should not be purchased because it does not yield a positive NPV.
What is the net present value?The net present value (NPV) shows the difference between the present value of cash inflows and the present value of cash outflows over a period of time.
It is determined by calculating the present values of cash flows using their present value factors as below:
Data and Calculations:Initial cash outlay = $1,061,500 ($1,020,000 + $22,000 + $19,500)
Salvage value = $599,000
Increase in net working capital = $19,500
Annual savings before tax = $386,000

Which of the following equations has roots x=−2, x=3 (multiplicity 2), and x=1, and passes through the point (0,-18)?
f(x) = x^4 - 5x^3 + x^2 + 21x - 18
=======================================================
Explanation:
The root x = -2 means x+2 is a factor. This is because we add 2 to both sides of x = -2 to get x+2 = 0.
Similarly, x = 3 leads to x-3 being another factor. It's a double root so we really have two copies of (x-3)
The last root is x = 1 which gives the factor x-1.
The four factors are: (x+2)(x-3)(x-3)(x-1)
Let's use the FOIL rule to expand out the first two factors
(x+2)(x-3) = x^2-3x+2x-6 = x^2-x-6
Do the same for the last two factors
(x-3)(x-1) = x^2-1x-3x+3 = x^2-4x+3
--------------------
So far we have:
(x+2)(x-3) = x^2-x-6
(x-3)(x-1) = x^2-4x+3
which leads to
(x+2)(x-3)(x-3)(x-1) = (x^2-x-6)(x^2-4x+3)
From here I'll use the box method to multiply these trinomials. Check out the diagram below. Each inner cell is the result of multiplying the headers. Example: x^2 times x^2 = x^4 in the upper left corner.
I've color-coded the inner cells to show the like terms. Add up those like terms:
-4x^3 + (-x^3) = -5x^33x^2 + (4x^2) + (-6x^2) = x^2-3x + 24x = 21xTherefore we end up with
(x^2-x-6)(x^2-4x+3) = x^4 - 5x^3 + x^2 + 21x - 18 which is choice B
--------------------
To verify this answer, plug in x = 0 and you should get y = -18 to show that we have the correct y intercept. If we tried this with choice A, then we'd get y = 18 which helps eliminate choice A.
Furthermore, plug in x = -2 into choice B and you should get y = 0 as an output. The same applies to x = 3 and x = 1. This confirms that they are roots or x intercepts of the polynomial.
Another way to verify the answer is to use something like WolframAlpha to type in (x+2)(x-3)(x-3)(x-1). Under the "expanded form" subsection, it says x^4 - 5x^3 + x^2 + 21x - 18

Answer:
-4sin(2x)
Step-by-step explanation:
Angle sum identities can be used to simplify this expression.
cos(a+b) = cos(a)cos(b) -sin(a)sin(b)sin(a+b) = sin(a)cos(b) +sin(b)cos(a)sin(2x) = 2sin(x)cos(x)NumeratorThe cosine function is even, so cos(-x) = cos(x). The cosine of the sum is ...
cos(90°+x) = cos(90°)cos(x) -sin(90°)sin(x) = -sin(x)
Then the numerator simplifies to ...
4cos(-x)cos(90°+x) = -4cos(x)sin(x) = -2sin(2x)
DenominatorMatching the denominator expression to the sine of a sum relation, we see
sin(30° -x)cos(x) +sin(x)cos(30° -x) = sin((30°-x) +x) = sin(30°) = 1/2
Simplified ExpressionThe simplified expression is the ratio of the simplified numerator to the simplified denominator:
= -sin(2x)/(1/2)
= -4sin(2x)

one of the two of A two digit is three times the other digit. if you interchange the digits of this two digit number and add the resulting number to the original number you get 88.what is the original number. give solution
ASAP PLEASE
Given that, one digit of a two digit number is three times the other digit.
Let assume that digit at ones place be x.
digit at ones place be x.So, digit at tens place be 3x.
digit at ones place be x.So, digit at tens place be 3x.So, two digit original number = 10 × 3x + 1 × x = 30x + x = 31x
Now, number formed on interchanging its digits, i.e.
Reverse number = 10 × x + 1 × 3x = 10x + 3x = 13x
According to statement, if we interchange the digits of this two digit number and add the resulting number to the original number, we get 88.
[tex]\begin{gathered}\sf \: 31x + 13x = 88 \\ \\ \end{gathered}[/tex]
[tex]\begin{gathered}\sf \: 44x = 88 \\ \\ \end{gathered}[/tex]
[tex]\begin{gathered}\sf \: x = \dfrac{88}{44} \\ \\ \end{gathered}[/tex]
[tex]\begin{gathered}\sf\implies \: x = 2 \\ \\ \end{gathered}[/tex]

Answer:
26 or 62
Step-by-step explanation:
If one of the two digits of a two-digit number is three times the other digit, then the options for the two-digit number are:
13 or 3126 or 6239 or 93If you interchange the digits of this two-digit number and add the resulting number to the original number, you get 88.
From inspection of the listed pairs of numbers, the only pair that sums to 88 is 26 and 62:

How many integers n satisfy both of the inequalities 4n + 3 < 25 and -7n + 5 < 24?
Answer:
1) All real numbers n such that [tex]n < 5.5[/tex]
2) All real numbers n such that [tex]n > -\frac{19}{7}[/tex]
Step-by-step explanation: How did I come up with such answers? Let me show you!
For the first problem, we just solve the inequality easily.
Subtracting 3 from both sides, we get:
4n < 22
Dividing by 4 from both sides, we get:
n < 5.5
Thus, all real numbers n that is less than 5.5 when plugged in for x will be less than 25.
For the next problem, it will be slightly trickier.
Subtracting 5 from both sides, we get:
-7n < 19
Dividing -7 from both sides, we get:
n > -19/7
Did you catch that? We just flipped the inequality sign and turned it from less than to a greater than. Whenever we divide by a negative number, the signs always change.
Thus, for all real numbers n greater than -19/7, when plugging in for x, you will get less than 24.
