Answer:Exponential functions follow all the rules of functions. However, because they also make up their own unique family, they have their own subset of rules. The following list outlines some basic rules that apply to exponential functions
Step-by-step explanation:The parent exponential function f(x) = bx always has a horizontal asymptote at y = 0, except when b = 1. You can’t raise a positive number to any power and get 0 or a negative number.
This rule is true because you can raise a positive number to any power. However, the range of exponential functions reflects that all exponential functions have horizontal asymptotes. All parent exponential functions (except when b = 1) have ranges greater than 0, or
The order of operations still governs how you act on the function. When the idea of a vertical transformation applies to an exponential function, most people take the order of operations and throw it out the window. Avoid this mistake.
You can’t multiply before you deal with the exponent.
You can’t have a base that’s negative. For example, y = (–2)x isn’t an equation you have to worry about graphing in pre-calculus. If you’re asked to graph y = –2x, don’t fret. You read this as “the opposite of 2 to the x,” which means that (remember the order of operations) you raise 2 to the power first and then multiply by –1. This simple change flips the graph upside down and changes its range to
A number with a negative exponent is the reciprocal of the number to the corresponding positive exponent. For instance, y = 2–3 doesn’t equal (–2)3 or –23. Raising any number to a negative power takes the reciprocal of the number to the positive power
When you multiply monomials with exponents, you add the exponents. F
When you have multiple factors inside parentheses raised to a power, you raise every single term to that power. For instance, (4x3y5)2 isn’t 4x3y10; it’s 16x6y10.
When graphing an exponential function, remember that the graph of an exponential function whose base number is greater than 1 always increases (or rises) as it moves to the right; as the graph moves to the left, it always approaches 0 but never actually get there. For example, f(x) = 2x is an exponential function, as is
The table shows the x and y values of these exponential functions. These parent functions illustrate that, as long as the exponent is positive, the graph of an exponential function whose base is greater than 1 increases as x increases — an example of exponential growth — whereas the graph of an exponential function whose base is between 0 and 1 decreases towards the x-axis as x increases — an example of exponential decay.
The graph of an exponential function who base numbers is fractions between 0 and 1 always rise to the left and approach 0 to the right. This rule holds true until you start to transform the parent graphs.

Nick wants to write
thank-you notes to 15 of
his friends. The cards
are sold in packs of 6.
How many does he need
to buy?
Answer:
Nick needs to buy 3 packs.
Step-by-step explanation:
If Nick buys 3 packs he will have 18 cards. If he uses 15 of them he will have 3 left over. If he only bought 2 packs he would be 3 cards short of the amount he really needed.
Answer:
Nick needs to buy 3 packs because if he buys 2 packs he'll have 12 cards which won't be enough. He will have an extra 3 cards remaining.
The positive difference of two integers is 13. The sum of the larger number and the square of the smaller is 103. Give your solution(s) as ordered pair (larger, smaller).
Answer:
(22, 9)
Step-by-step explanation:
The positive difference of two integers is 13. The sum of the larger number and the square of the smaller is 103. Give your solution(s) as ordered pair (larger, smaller). I'll call the two integers a and b.
a - b = 13 a + b² = 103
+b +b
a = 13 + b plug this into the second equation
a + b² = 103
(13+b) + b² = 103 subtract 103 from both sides to get one side equal to zero
-103 -103
b² + b - 90 = 0 what factors (two numbers multiply) to -90 that also add up
to 1? The only two that work are -9 and 10.
(b-9)(b+10) = 0 so b-9 = 0 or b+10 = 0
+9 +9 or -10 -10
b = 9 or b = -10 but both numbers must be positive
b = 9 and a = 13 + b so a = 13 + 9 = 22

Flippin Middle School spends $11 for every workbook it buys. At most how many workbooks can Flippin Middle school buy if it has $44 to spend?
Answer:
4
Step-by-step explanation:
4 because 11x4=44
Flippin Middle School can buy at most 4 workbooks if it has $44 to spend.
To determine the maximum number of workbooks that Flippin Middle School can buy with $44, we need to divide the total amount of money available by the cost of each workbook.
Let's denote the number of workbooks that can be bought as [tex]\( W \)[/tex], and we know that each workbook costs $11. Therefore, the total cost for [tex]\( W \)[/tex] workbooks would be [tex]\( 11W \)[/tex].
Given that the school has $44 to spend, we can set up the following inequality to find the maximum number of workbooks that can be purchased:
[tex]\[ 11W \leq 44 \][/tex]
Now, we divide both sides of the inequality by 11 to solve for [tex]\( W \)[/tex]:
[tex]\[ W \leq \frac{44}{11} \][/tex]
[tex]\[ W \leq 4 \][/tex]
Since [tex]\( W \)[/tex] must be a whole number because one cannot buy a fraction of a workbook, the maximum number of workbooks that Flippin Middle School can buy is 4.

The Federal Unemployment Tax Act (FUTA) tax rate is 6% of the first $7,000 paid to each employee per year.
So,
For person 1:
The FUTA tax is 6% of $3500 = $210.
For person 2:
The FUTA tax is 6% of $7000 = $420
Since the FUTA tax is limited to $7000 of wages per employee per year.
For person 3:
The FUTA tax is 6% of $7000 = $420.
Since the FUTA tax is limited to $7000 of wages per employee per year.
The maximum FUTA deduction would be the sum of the FUTA tax for each employee.
= $210 + $420 + $420
= $1050.
Therefore,
The maximum FUTA deductions for the first quarter is $1050.

Determine the explicit formula of the following sequence -3,-18,-108...
Answer:
[tex]a_{n}[/tex] = - 3[tex](6)^{n-1}[/tex]
Step-by-step explanation:
Note the common ratio r between consecutive terms, that is
r = - 18 ÷ - 3 = - 108 ÷ - 18 = 6
This indicates the sequence is geometric with n th term ( explicit formula )
[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]
where a is the first term and r the common ratio
Here a = - 3 and r = 6, thus

Y=3.2x+5 what is the answer for y
Answer:
Step-by-step explanation:
Y = 3.2x + 5 is a linear function with slope 3.2 and y-intercept 5.
For any x value you choose to substitute for x, you'll obtain a unique y value. For example, if we were to substitute -3 for x, we'd get:
f(-3) = y = 3.2(-3) + 5, or y = -9.6 + 5 = -4.6
There is only one y result for each choice of x.
Y=3.2x+5 alone does not have an "answer." Again: You must pick your own x values and for each such value you must calculate y.

The airline distance from Rome, Italy to Paris, France is 697 miles. The distance from Paris to Berlin,
Germany is 545 miles and the distance from Berlin to Rome is 734 miles. What is the angle formed from
Berlin to Paris to Rome?
Answer:
Angle Rome to Paris = 44.68°
Angle Paris to Berlin = 71.26°
Angle Berlin to Rome = 64.06
Step-by-step explanation:
See attachment for diagram illustration for this.
Let represent distance from Rome to Paris as a, distance from Paris to Berlin as b, and distance from Berlin to Rome as c.
Therefore we say
a = 697miles, b = 545miles, c = 734miles
To find the respectively angle formed from, Berlin to Paris to Rome, we will apply the cosine rule, which states that:
c² = a² + b² - 2abCosC
734² = 697² + 545² - 2(697*545)cosC
2(697*545)cosC = 697² + 545² - 734²
759739 cosC = 244078
cosC = 244078/759739
cosC = 0.3212
C = cos-¹0.3212
C = 71.26°
To get angle B, we will apply the sine rule, which states that:
a/sineA = b/sineB = c/sineC
Therefore we have
545/sineB = 734/sine71.26
= 545/sineB = 734/0.947
= 545/sineB = 734/0.947
= 545/sineB = 775.08
SineB = 545/775.08
B = sine-¹0.7032
B = 44.68°
Angle A = 180 - (B+C) angle in a triangle
A = 180 - (44.68 + 71.26)
A = 180 - 115.94
A = 64.06°
A = 64.06°
B = 44.68°
C = 71.26°

Answer:
The Angle formed from Rome to Berlin(R)=44.68 degreesThe Angle formed from Paris to Berlin(P)=71.26 degreesThe Angle formed from Berlin to Paris(B)=64.06 degreesStep-by-step explanation:
The movement of the airplane can be represented using a triangle. In Triangle PRB, we are required to find Angles P, R and B.
Using Law of Cosines
[tex]cos R=\frac{p^2+b^2-r^2}{2pb} \\cos R=\frac{734^2+697^2-545^2}{2*734*697}\\R=arcCos\left(\frac{734^2+697^2-545^2}{2*734*697}\right)\\R=44.68^0[/tex]
Using law of Sines
[tex]\frac{r}{sin R}=\frac{p}{SIn P} \\\frac{545}{sin 44.68}=\frac{734}{Sin P} \\\text{Cross Multiply}\\545 X Sin P=734 X sin 44.68\\Sin P=\frac{734 X sin 44.68}{545} \\P=arcSin\left(\frac{734 X sin 44.68}{545}\right)\\P=71.26^0[/tex]
Now,
P+R+B=180 degrees (Sum of Angles in a Triangle)
[tex]71.26^0+44.68^0+B=180^0\\B=180^0-[71.26^0+44.68^0]\\B=64.06^0[/tex]

Ms. Sung budgets a maximum of $320 per month for groceries. She grocery shops 4 times a month. Which inequality can be used to find the possible values of x, the amount she can spend at the grocery store during each shopping trip?
Answer:
Less than or equal to $80
Step-by-step explanation:
If she get $320 a month and shops 4 times a month, you have to find the unit rate. This is so that you know the maximum amount of money she can spend.
320÷4=80
She can't go above $80, but she can spend any amount under $80. Than means the amount she can spend is less than or equal to $80.
The inequality that can be used to find the possible values of x is x≤80.
Maximum budget per month =$320
Number of times Ms Sung goes to a shop a month = 4
Amount spent on each shopping trip = x
What is inequality?Inequality is a statement that equates to two expressions.
So, the amount spent on 4 shopping trips = 4x
The maximum amount she can spend on all trips=$320
This means, [tex]4x\leq 320[/tex]
So, [tex]x\leq 80[/tex]
Hence, the inequality that can be used to find the possible values of x is x≤80.
