Consider the function f(x) = 3x and a translation of f(x) named g(x). Janeen created a table for select values of x. Her table is shown below. What can be concluded about the relationship between the two functions? Check all that apply.
The functions have the same base.
The functions have the same range.
The functions have the same exponent.
The functions have the same domain.
g(x) is a translation left 1 unit.
g(x) is a translation right 2 units.
g(x) is a translation up 2 units.
Answers
Answer:
The correct options are:
So, these functions have the same range.
The functions have the same base.
The functions have the same domain.
g(x) is a translation left 1 unit.
Step-by-step explanation:
According to the table, both are exponential functions.
We have that
[tex]f(x) = 3^{x}[/tex]
[tex]g(x) = 3^{x+1}[/tex]
Lets see each affirmation:
The functions have the same base.
An exponential function [tex]a^{x}[/tex] has base a.
In this problems, both f and g have base 3.
The functions have the same range.
The range of f are all the values that f can assume. That is, all the positive numbers.
The range of g are all the values that g can assume. That is, also all the positive numbers.
So, these functions have the same range.
The functions have the same exponent.
An exponential function [tex]a^{x}[/tex] has exponent x.
f has exponent x and g has exponent x + 1. So those functions do not have the same exponent.
The functions have the same domain.
Yes, they both have x = {0,1,2,3} as domain.
g(x) is a translation left 1 unit.
g(x) = f(x+1). So yes, g(x) is a translation left 1 unit.
g(x) is a translation right 2 units.
g(x) is not f(x-2). So g(x) is not a translation right 2 units.
g(x) is a translation up 2 units.
g(x) is not f(x) + 2. So g(x) is not a translation up 2 units.

4: 2 meters squared per minute
5: 7 meters per minute
This is actually for a game but I'm really bad at math.
Answers
Answer:
The rate of change of the area of the circle when the radius is 4 meters = 2 meters²/minute ⇒ answer 4
Step-by-step explanation:
* Lets revise the chain rule in the derivative
- If dy/da = m and dx/da = n, and you want to find dy/dx
∴ dy/dx = dy/da ÷ dx/da = m ÷ n = m/n
* In our problem we have
- The rate of increasing of the circumference dC/dt = 0.5 meters/minute
- We need the find the rate of change of the area of the circle
when the radius is 4 meters
- The common element between the circumference and the area
of the circle is the radius of the circle
* We must to find dC/dr and dA/dr and use the chain rule to
find dA/dr
- Find the rate of change of the radius dr/dt
∵ C = 2πr
- Find the derivative of C with respect to r
∴ dC/dr = 2π ⇒ (1)
∵ dC/dt = 0.5 meters/minute ⇒ (2)
- Divide (1) by (2) to get dr/dt by using chain rule
∵ dC/dt ÷ dC/dr = 0.5 ÷ 2π
∴ dC/dt × dr/dC = 0.5 × 1/2π ⇒ cancel dC together and change
0.5 to 1/2
∴ dr/dt = 1/2 × 1/2π = 1/4π ⇒ (3)
- Find the rate of change of the area dA/dt
∵ A = πr²
- Find the derivative of A with respect to r
∴ dA/dr = 2πr
∵ r = 4
∴ dA/dr = 2π(4) = 8π ⇒ (4)
- Multiply (4) by (3) to get dA/dt by using chain rule
∵ dA/dr × dr/dt = 8π × 1/4π ⇒ divide 8 by 4 and cancel π
∴ dA/dt = 2 meters²/minute
* The rate of change of the area of the circle when the radius is
4 meters = 2 meters²/minute
The rate of change of the area of the circle when the radius is 4 meters is 2m²/min
How to calculate the circumference and area of a circleThe formula for calculating the circumference of a circle is expressed as;
C = 2πr
where:
r is the radius of the circle
The rate of change of circumference is expressed as:
[tex]\frac{dC}{dt} = \frac{dC}{dr} \times \frac{dr}{dt} \\0.5=2 \pi \times \frac{dr}{dt}\\ \frac{dr}{dt} = \frac{0.5}{2\pi} \\ \frac{dr}{dt} = 0.0796 m/min[/tex]
The change in area of the circle is expressed as:
[tex]\frac{dA}{dt} = \frac{dA}{dr} \times \frac{dr}{dt}\\ \frac{dA}{dt} =2 \pi r\times 0.0796\\ \frac{dA}{dt} = 2(3.14)(4)\times 0.0796\\ \frac{dA}{dt} = 2m^2/min\\[/tex]
Hence the rate of change of the area of the circle when the radius is 4 meters is 2m²/min

How do the values in Pascal’s triangle connect to the coefficients?
Answers
Explanation:
Each row in Pascal's triangle is a listing of the values of nCk = n!/(k!(n-k)!) for some fixed n and k in the range 0 to n. nCk is the number of combinations of n things taken k at a time.
If you consider what happens when you multiply out the product (a +b)^n, you can see where the coefficients nCk come from. For example, consider the cube ...
(a +b)^3 = (a +b)(a +b)(a +b)
The highest-degree "a" term will be a^3, the result of multiplying together the first terms of each of the binomials.
The term a^b will have a coefficient that reflects the sum of all the ways you can get a^b by multiplying different combinations of the terms. Here they are ...
(a +_)(a +_)(_ +b) = a·a·b = a^2b(a +_)(_ +b)(a +_) = a·b·a = a^2b(_ +b)(a +_)(a +_) = b·a·a = a^2bAdding these three products together gives 3a^2b, the second term of the expansion.
For this cubic, the third term of the expansion is the sum of the ways you can get ab^2. It is essentially what is shown above, but with "a" and "b" swapped. Hence, there are 3 combinations, and the total is 3ab^2.
Of course, there is only one way to get b^3.
So the expansion of the cube (a+b)^3 is ...
(a +b)^3 = a^3 + 3a^2b +3ab^2 +b^3 . . . . . with coefficients 1, 3, 3, 1 matching the 4th row of Pascal's triangle.
__
In short, the values in Pascal's triangle are the values of the number of combinations of n things taken k at a time. The coefficients of a binomial expansion are also the number of combinations of n things taken k at a time. Each term of the expansion of (a+b)^n is of the form (nCk)·a^(n-k)·b^k for k =0 to n.
The values in Pascal's triangle are the coefficients in the binomial expansion of (x+y)^n. Each row in the triangle represents the coefficients for a certain power of the binomial being expanded.
Explanation:In mathematics, Pascal's triangle is a triangular array of numbers where each number is the sum of the two immediately above it. Each row of Pascal's Triangle corresponds to the coefficients in the binomial expansion of (x+y)n. For example, the third row of the Pascal's triangle is 1, 2, 1, which are the coefficients for the expansion of (x+y)2, yielding x2 + 2xy + y2. To put it differently, the values in Pascal's triangle provide the coefficients for each term in the binomial expansion. The index of the row in the triangle indicates the power of the binomial being expanded. So, effectively, the values in Pascal’s triangle connect directly to the coefficients in an algebraic binomial expansion.

Answers
Answer:
A. Step 1: Multiply 1 × 5.
Step 2: Multiply 2 × 3.
Step 3: Add the two products.
Step-by-step explanation:
The total number of miles hiked will be the sum of the numbers of miles hiked each day. Each day, the number of miles hiked can be computed by multiplying time by speed:
distance = speed × time
So, the total number of miles hiked is ...
total miles = miles on day 1 + miles on day 2 . . . . . (sum, not a difference—eliminates choice B)
total miles = (speed on day 1)×(time on day 1) + (speed on day 2)×(time on day 2) . . . . . (sum of products—eliminates choices C and D)
Choice A correctly describes the computation.

Step-by-step explanation:
Volume of cylinder A

Where height of A is ha
If the height of B is twice the corresponding height of A
hb = 3ha
Volume of B Vb = 1/3πr²(3ha)...(2)
If volume of A is 13cm³ and
Va = 1/3πr²ha
Then 13 = 1/3πr²ha
39 = πr²ha
πr² = 39/ha ... (3)

Vb = 1/3(39/ha)(3ha)
Vb = 39/ha × ha

Answer:
The required functions are [tex]f(x)=x^2+3[/tex], [tex]g(x)=2x^2-3[/tex], [tex]h(x)=x^2-3[/tex] and [tex]j(x)=-2x^2-3[/tex].
Step-by-step explanation:
The vertex from of a parabola is
[tex]y=a(x-h)^2+k[/tex]
Where, (h,k) is the vertex of parabola is a is the vertical stretch factor.
If a is negative, then it is downward parabola and if a is positive then it is an upward parabola.
If |a|<1, then it is compressed vertical and if |a|>1, then it is stretched vertically.
The graph of f(x) has vertex at (0,3) and it is not stretch vertically so the value of a is 1. So, the function f(x) is defined as
[tex]f(x)=1(x-0)^2+3[/tex]
[tex]f(x)=x^2+3[/tex]
The graph of g(x) has vertex at (0,-3) and it is stretch vertically by factor 2 so the value of a is 2. So, the function g(x) is defined as
[tex]g(x)=2(x-0)^2-3[/tex]
[tex]g(x)=2x^2-3[/tex]
The graph of h(x) has vertex at (0,-3) and it is not stretch vertically so the value of a is 1. So, the function h(x) is defined as
[tex]h(x)=1(x-0)^2-3[/tex]
[tex]h(x)=x^2-3[/tex]
The graph of j(x) has vertex at (0,-3) and it is stretch vertically by factor 2 and it is downward so the value of a is -2. So, the function j(x) is defined as
[tex]j(x)=-2(x-0)^2-3[/tex]
[tex]j(x)=-2x^2-3[/tex]
Therefore the required functions are [tex]f(x)=x^2+3[/tex], [tex]g(x)=2x^2-3[/tex], [tex]h(x)=x^2-3[/tex] and [tex]j(x)=-2x^2-3[/tex].

Pencils are on sale for $0.99 per dozen. Ms. Klein buys 8 pencils for each of her 96 students. How much will she spend on pencils?
Answers
Answer:
$63.36
Step-by-step explanation:
First we need to determine how many pencils are needed
8 pencils times 96 students
8*96 =768 pencils
A dozen is 12 pencils
Divide the number of pencils needed by 12 to determine how many dozen pencils are needed
768/12 =64
We need 64 dozen pencils
They cost .99 per dozen
64*.99 =63.36
It will cost $63.36 for the pencils

Question 5(Multiple Choice Worth 7 points)
Use graphs and tables to find the limit and identify any vertical asymptotes of limit of 1 divided by the quantity x minus 3 as x approaches 3 from the left.
∞ ; x = -3
-∞ ; x = -3
-∞ ; x = 3
1 ; no vertical asymptotes
Answers
Answer:
-∞ ; x = 3
Step-by-step explanation:
The graph tends toward -∞ as x approaches 3 from the left. Thus there is a vertical asymptote at x=3, the value of x that makes the denominator zero.
If the price of theater tickets increases at 8% per year, about how long will it take to double the price?
Answers
Answer:
[tex]9\ years[/tex]
Step-by-step explanation:
Let
P----> the initial price of the ticket
y ---> the price of the ticket after t years
t---> the time in years
we know that
100%+8%=108%=108/100=1.08
so
[tex]y=P(1.08)^{t}[/tex] ----> equation A
If the price is doubled
then
[tex]y=2P[/tex] -----> equation B
equate equation A and equation B and solve for t
[tex]2P=P(1.08)^{t}[/tex]
Simplify
[tex]2=(1.08)^{t}[/tex]
Apply log both sides
[tex]log(2)=t*log(1.08)[/tex]
[tex]t=log(2)/log(1.08)=9\ years[/tex]
It will take approximately 9 years for the price of theater tickets to double at an annual increase of 8%.
To solve this problem, we can use the Rule of 70, which is a quick and easy way to estimate the number of years required for a quantity to double at a constant growth rate. The Rule of 70 is given by the formula:
[tex]\[ \text{Years to double} \approx \frac{70}{\text{Annual growth rate}} \][/tex]
Given that the annual growth rate is 8%, we can apply this formula:
[tex]\[ \text{Years to double} \approx \frac{70}{8} \] \[ \text{Years to double} \approx 8.75 \][/tex]
Since we cannot have a fraction of a year in this context, we round to the nearest whole number. Therefore, it will take approximately 9 years for the price to double.
Partial qoutients 231÷11
Answers
Answer:
21
Step-by-step explanation:
We are to find partial quotients of 231 ÷ 11
In other words the question asks: How many 11s are there in 231
First, there are twenty 11s in 220 i.e 20 × 11 = 220
Then, subtract 220 from 231 to get 11
Finally ask yourself: How many 11s are in eleven? Definitely its only one 11.
So there are 20 + 1 elevens in 231
Or, there are 21 elevens in 231
if a coin is flipped 10 times what is the probability that it will show all heads or all tails?
A. 1/2
B. 1/512
C. 1/1,022
D. 1/1,024
E. 1/2,048
Answers
The answer would be A
If a coin is flipped 10 times then the probability that it will show all heads or all tails is 1/512.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The probability of getting all heads or all tails on 10 flips in a row is the sum of the probabilities of getting all heads and getting all tails.
P(all heads or all tails) = P(all heads) + P(all tails)
Since the coin flips are independent events, we can use the multiplication rule to find the probability of getting all heads or all tails:
P(all heads) = (1/2)¹⁰ = 1/1024
P(all tails) = (1/2)¹⁰ = 1/1024
So, the probability of getting all heads or all tails is:
P(all heads or all tails) = P(all heads) + P(all tails)
= 1/1024 + 1/1024
= 1/512
Therefore, if a coin is flipped 10 times then the probability that it will show all heads or all tails is 1/512.
