Answer:
A general exponential equation is written as:
f(x) = A*(r)^x
Where:
A is the initial value, this is the value that the function takes when x = 0.
r is the rate of growth
x is the variable.
In this case, the function is:
f(x) = 2*(4)^x
The initial value is:
f(0) = 2*(4)^0 = 2*1 = 2
The initial value is 2.
And the rate of growth is 4.
So Martin seems to mixed these two values (he said initial value = 4, and rate = 2, which is the opposite of what we found)

8. A truck is carrying peach juice, pear juice,
and grape juice bottles in a ratio of 4:3:5. If
there are 76 peach juice bottles, then how many
pear juice bottles are there?
Answer:
57 pear juices
Step-by-step explanation:
because we know we have 76 peach juices and the ratio is 4, so we get 19. This means that 19=x. And then we multiply 19 by 3 and we get 57.

Activity
Andrew is paid $4 per hour for the first 30 hours he works each week. He makes $5 per hour for each hour he works over 30 hours per week. In
other words, total wages = fixed wages for 30 hours + additional wages at $5 per hour.
Apply function notation to answer the following questions about Andrew's wages.
Part D. How does the function notation in this example compare with the standard notation
Answer:
Step-by-step explanation:
For the first 30 hours, Andrew will earn 4(30) = $120. For each additional hour beyond 30 that Andrew works, he will earn 5(h - 30). Therefore, the function that gives Andrew's total wages when he works more than 30 hours is:
w = 120 + 5(h - 30).
So, if he works 35 hours, he will earn:
120 + 5(35 - 30) = 120 + 5(5) = 120 + 25 = $145.
If he works 42 hours, he will earn:
120 + 5(42 - 30) = 120 + 5(12) = 120 + 60 = $180.
I hope this helps!

2/5 ? 7/10
Answer:
2/5 < 7/10
I think this is it
Answer:
2/5 < 7/10
The least common denominator is 10 so if you do 5*2 = 10 and 2*2 = 4 then compare it to 7/10, it would be less than because 4/10 is not greater than 7/10.

Answer:
slope: 1.25
Part B: The order in which the points are given does not change the value of the slope
Step-by-step explanation:
Part A. Given two points we can find slope using the slope formula
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Given the points ( -6, 1/2) and ( -4,3 )
We plug in the y values and x values (starting with the last point give )
[tex]m=\frac{3-.5}{-4-(-6)} \\3-\frac{1}{2} =2.5\\-4-(-6)=2\\\frac{2.5}{2} =1.25\\[/tex]
so we can conclude that the slope of a line that passes through the points ( -6, 1/2) and ( -4,3 ) is 1.25
Part B. The order in which the points are given does not change the value of the slope
Observe -
* flip the order in which the points are given *
given (-4,3) and (-6,1/2)
we use the same formula
*plug in the y and x values starting with the last point*
[tex]m=\frac{.5-3}{-6-(-4)} \\.5 - 3=-2.5\\-6-(-4)=-2\\\frac{-2.5}{-2} =1.25[/tex]
The slope still equals 1.25 meaning that the order in which the points are given does not matter.
If the loss incurred on selling an article is 7/20 of the cost price, then find the loss percentage.
Answer: The loss percentage = 65%
Step-by-step explanation:
Let x be the cost price.
As per given,
Selling price = [tex]\dfrac{7}{20}x[/tex]
Loss =Cost price - Selling price
[tex]=x-\dfrac{7}{20}x\\\\=\dfrac{20-7}{20}x\\\\=\dfrac{13}{20}x[/tex]
The loss percent = [tex]\dfrac{loss}{Cost\ price}\times100[/tex]
[tex]=\dfrac{\dfrac{13}{20}x}{x}\times100\\\\=\dfrac{13}{20}\times100\\\\=13\times5\%\\\\=65\%[/tex]
Hence, the loss percentage = 65%
The volume of a sphere is 62,208π cubic centimeters. Find the radius
Answer:
The radius of the sphere is 36 centimeters.
Step-by-step explanation:
Given that the volume of a sphere is 62,208π cubic centimeters, to find the radius the following calculation must be performed, knowing that the formula to obtain the volume of a sphere is V = 4/3 π x radius³:
62,208 x 3.14 = 4/3 x 3.14 x X³
195,333.12 = 4/3 x 3.14 x X³
195,333.12 = 4.18666 x X³
195,333.12 / 4.18666 = X³
46.656 = X³
³√ 46,656 = X
36 = X
Therefore, the radius of the sphere is 36 centimeters.
What is the 12th term of the geometric sequence if a1= 30 and r=4.
Answer:

Which fraction is equivalent to the fraction below?
18/24
Answer:
6/8 , 12/16 , 48/64
Step-by-step explanation:
f(3) = 12 for a geometric sequence that is defined
recursively by the formula f(n) = 0.5 ∙ f(n – 1), where
n is an integer and n > 0.
Write the equation in explicit form.
Answer:
[tex]f(n) = 96 * 0.5^n[/tex]
Step-by-step explanation:
Given
[tex]f(3) = 12[/tex]
[tex]f(n) = 0.5 * f(n-1)[/tex]
Required
Write as an explicit function
When n = 3, we have:
[tex]f(3) = 12[/tex]
[tex]f(3) = 0.5 * f(3-1)[/tex]
[tex]f(3) = 0.5 * f(2)[/tex]
Substitute: [tex]f(3) = 12[/tex]
[tex]12 = 0.5 * f(2)[/tex]
Solve for f(2)
[tex]f(2) = 12/0.5[/tex]
[tex]f(2) = 24[/tex]
So, we have;
[tex]f(3) = 12[/tex]
[tex]f(2) = 24[/tex]
Since it is a geometric sequence, calculate the common ratio (r)
[tex]r = \frac{f(3)}{f(2)}[/tex]
[tex]r = \frac{12}{24}[/tex]
[tex]r = 0.5[/tex]
Calculate the first term using:
[tex]r = \frac{f(2)}{f(1)}[/tex]
Solve for f(1)
[tex]f(1) = \frac{f(2)}{r}[/tex]
[tex]f(1) = \frac{24}{0.5}[/tex]
[tex]f(1) = 48[/tex]
The explicit function is then calculated as:
[tex]f(n) = f(1) * r^{n-1[/tex] ----nth term of a gp
[tex]f(n) = 48 * 0.5^{n-1[/tex]
Split the exponent
[tex]f(n) = 48 * \frac{0.5^n}{0.5^1}[/tex]
[tex]f(n) = 48 * \frac{0.5^n}{0.5}[/tex]
[tex]f(n) = 96 * 0.5^n[/tex]

x = 5
Step-by-step explanation:
Hope that this helps! :)
Have a great rest of your day/night!
Answer:
x = 5
Step-by-step explanation:
2x + 5 = 4x - 5First you will need to add 5 to each side.
2x + 10 = 4xThen you need to subtract 2x to each side.
10 = 2xLastly, you will need to divide each side by 2.
5 = xHave a nice day!Solve. 40 = -10x + 20
Answer:

Help!! Solve 1 1/4 + 5 5/6
Answer:
7 2/24
Step-by-step explanation:
We can start by making the denominators the same (the bottom number)
1 1/4+5 5/6
1 6/24+ 5 20/24=7 2/24
Answer:
so what you would want to do is get your fraction into improper fractions and to do that you multiply the whole number by the denominator and add it to your numerator, once you do that you get 5/4, and 35/6, now we want to get common denominators, so we multiply 5/4, by 6/6, and 35/6 by 4/4 which would get us 30/24 and 140/24 then we add them and get 170/24 and then simplify, which gets you 85/12 and then put it into a mixed number which is 7 1/12

Volume? Correct answers please
Answer:
V = 1385.44
Step-by-step explanation:
The equation for volume is V = π r 2 h! Where V = volume, r = radius (half the diameter), and h = height. Now lets substitute what we know into this equation!
Since we are giving the diameter (14) we must divide by 2 to find the radius.
14 ÷ 2 = 7
Radius = 7
Height = 9
V = ?
Time to plug these values in!
V = π [tex]7^{2}[/tex] (9)
We have to distribute pi to 7 square that term and then multiply the value by 9.
V = 1385.44
Hope this Helps! :)

Answer: I think 8?
Step-by-step explanation:
You might be adding the 6 so therefore maybe you do 6+2= 8 if the median was eqaul to 6.
If this isnt right, I'm sorry!
Answer: 1
The set is:
6 1 5 4 8 7 2 1 2 2
First: We get the median of the original set. To do this we change it from highest to lowest.
1 1 2 2 2 4 5 6 7 8
Then we take the middle number of this set which is the median
2 and 4 are the middle so the median is 3
The median of set 1 is 3
Second: We get the median of the set but with another 6 added
1 1 2 2 2 4 5 6 6 7 8
Take the middle number of this set which is the median
4
The median of set 2 is 4
From this we know the median increases by 1 if the number 6 is added!
