Answer:
The value of g'(10)=[tex]\frac{(-1)}{16}[/tex]
Step-by-step explanation:
Given function is f(x)=[tex]\frac{4}{x} + 2[/tex]
Take f(x)=y
y=[tex]\frac{4}{x} + 2[/tex]
Subtract 2 from both side.
y-2=[tex]\frac{4}{x}[/tex]
x=[tex]\frac{4}{y-2}[/tex]
The inverse of f(x) is written as [tex] \frac{4}{y-2}[/tex]
It is said as g is inverse of f
g(y)=\frac{4}{y-2}[/tex]
g(y)=[tex]\frac{4}{y-2}[/tex]
g(10)=[tex]\frac{4}{10-2}[/tex]
g(10)=[tex]\frac{1}{2}[/tex]
Differentiating both sides we get,
g'(y)=[tex]\frac{4(-1)}{(y-2)^{2}}+0[/tex]
g'(y)=[tex]\frac{(-4)}{(y-2)^{2}}[/tex]
To find g'(10)=[tex]\frac{(-4)}{(10-2)^{2}}[/tex]
g'(10)=[tex]\frac{(-1)}{16}[/tex]
Is mean absolute deviation a measure of center
measure of variation ?
or a
A. measure of center
B. measure of variation
The mean absolute deviation is a measure of variation in a dataset, not its center. It helps indicates how spread out the data is from the mean value.
Explanation:The mean absolute deviation is not a measure of center,instead, it is a measure of variation. The center of a data set is typically represented by measures like the mean, median, or mode. These describe the common, central value in the dataset.
Conversely, the mean absolute deviation is a statistical tool used for understanding the dispersion or variation in a set of values. It gives an average of the absolute differences between each data point and the mean of the data set. This helps identify how spread out the data is from the mean.

Find an exponential function with a horizontal asymptote y = - 7 whose graph contains the points (0.- 6) and (1,6).
The exponential function with a horizontal asymptote y = -7 that passes through the points (0, -6) and (1, 6) is:
y = [tex]e^{(ln(13)x)} - 7[/tex].
To find an exponential function with a horizontal asymptote y = -7 that passes through the points (0, -6) and (1, 6), we can use the general form of an exponential function:
[tex]y = A * e^{(kx)} + C[/tex]
where A is the initial value, k is the growth/decay rate, e is the base of the natural logarithm (approximately 2.71828), x is the independent variable, and C is the y-coordinate of the horizontal asymptote.
Step 1: Determine the value of C (the y-coordinate of the horizontal asymptote):
Since the asymptote is y = -7, we set C = -7.
Step 2: Use the given points to find A and k:
For point (0, -6):
-6 = A * e⁰ - 7
-6 + 7 = A
A = 1
For point (1, 6):
6 = 1 * [tex]e^{(k*1)[/tex] - 7
13 = [tex]e^{k[/tex]
Step 3: Solve for k:
Take the natural logarithm of both sides: ln(13) = k
Step 4: Write the exponential function:
The exponential function with a horizontal asymptote y = -7 that passes through the points (0, -6) and (1, 6) is:
y = [tex]e^{(ln(13)x)} - 7[/tex].
This function will have a horizontal asymptote at y = -7 and pass through the given points (0, -6) and (1, 6).

use a tape diagram to solve and if-then statement
Answer:
p=11 packets were purchased
Step-by-step explanation:
30+11p=151
11p=121
then
121/11
so
p=11
Hope I understood the question :/
Answer:
Step-by-step explanation:
I believe the correct answer is that Andrew's Math Teacher purchased 11 packets of 10 tests each, meaning that the total number of test would be 110. I got this by subtracting the $30 entrance fee from the $151. After doing this we are left with $121. I then divided the $121 by the cost per packet and I was left with 11 packets. Since every packet contains 10 tests I multiplied that by the number of packets to get the final answer... 110 tests purchased.
The cost of a babysitting on a cruise is 10 for the first hour, and 12 for each additional hour. If the total cost of baby Aaron was 58, how many hours was Aaron at the sitter?
Answer:
5 hours was Aaron at the sitter
Explanation:
Cost of baby sitting for the first hour: 10
Cost of baby sitting for additional hour= 12
Total cost of babysitting= 58
Since the cost of first hour is 10
Hence the remaining cost after first hour
= 54-10
=48
Which means 1 hour is consumed in the first hour
Now to calculate the remaining hours for every additional hour
= [tex]\frac{48}{12}[/tex]
=4 hours
Hence the total hour Aaron was with the sitter
= 1 hour + 4 hours
= 5 hours
James has a bag 77 of nickels and dimes. The total value of coins is $6.60. How many dimes does James have?
James has 55 dimes in the bag
Step-by-step explanation:
The given is:
James has in a bag 77 of nickels and dimesThe total value of coins is $6.60We need to find how many dimes James has
Assume that the number of nickels is x and the number of
dimes is y in the bag
∵ There are x nickels in the bag
∵ There are y dimes in the bag
∵ There are 77 coins in the bag
∴ x + y = 77 ⇒ (1)
∵ 1 nickel = 5 cents
∴ The value of nickles in the bag = 5x cents
∵ 1 dime = 10 cents
∴ The value of dimes in the bag = 10y cents
∵ The total value of coins is $6.60
∵ 1 dollar = 100 cents
∴ $6.60 = 6.60 × 100 = 660 cents
∴ 5x + 10y = 660 ⇒ (2)
Now we have a system of equations to solve it
Multiply equation (1) by -10 to eliminate y
∵ -10x - 10y = -770 ⇒ (3)
- Add equations (2) and (3)
∴ -5x = -110
- Divide both sides by -5
∴ x = 22
Substitute the value of x in equation (2) to find y
∵ 22 + y = 77
- Subtract 22 from both sides
∴ y = 55
∴ The number of dimes is 55
James has 55 dimes in the bag

The zurassic zoo charges $11 each for adult admissions and $4 each for each child. The total bill for the 138 people from a school trip was $839. How many adults and how many children went to the zoo?
The number of adults = 41
The number of children = 97
Step-by-step explanation:
Let x be the number of adults and
y be the number of children
then according to the given conditions
[tex]x+y = 138\ \ \ Eqn\ 1\\11x+4y = 839\ \ \ Eqn\ 2[/tex]
From equation 1:
x = 138-y
Putting in equation 2
[tex]11(138-y)+4y = 839\\1518-11y+4y = 839\\1518 -7y = 839\\-7y = 839-1518\\-7y = -679\\[/tex]
Dividing both sides by -7
[tex]\frac{-7y}{-7} = \frac{-679}{-7}\\y = 97[/tex]
Putting y = 97 in equation 1
[tex]x+ 97 = 138\\x = 138-97\\x = 41[/tex]
Hence,
The number of adults = 41
The number of children = 97

Answer:
The values are x = 0° or x = 60°
Step-by-step explanation:
Given:
[tex]\cos x + \frac{1}{\sqrt{3} }\times \sin x = 1[/tex]
Let it be in the form of
[tex]a\cos x + b\sin x = 1[/tex] such that
a = 1
[tex]b=\frac{1}{\sqrt{3} }[/tex]
We have
[tex]\sqrt{(a^{2}+b^{2} )}=\sqrt{(1^{2}+(\frac{1}{\sqrt{3} }) ^{2} )}\\=\sqrt{\frac{4}{3}}\\=\frac{2}{\sqrt{3} }[/tex]
Now, Dividing both the side by [tex]\frac{2}{\sqrt{3} }[/tex] we get
[tex]\frac{\sqrt{3} }{2}\cos x + \frac{1}{2}\sin x =\frac{\sqrt{3} }{2}\\[/tex]
We Know
[tex]\sin 60 =\frac{\sqrt{3} }{2}\\and\\\cos 60 = \frac{1}{2}[/tex]
Now by replacing with above values we get
[tex]\sin 60\times \cos x + \cos 60\times \sin x = \frac{\sqrt{3} }{2}\\[/tex]
Also we have formula
[tex]\sin A\times \cos B + \cos A\times \sin B = \sin (A+B)[/tex]
By applying the above Formula we get
[tex]\sin (60+x)=\frac{\sqrt{3} }{2}\\[/tex]
Also ,
[tex]\sin (60)=\frac{\sqrt{3} }{2}\\and\\\sin (120)=\frac{\sqrt{3} }{2}[/tex]
Comparing we get
60 + x = 60 or 60 + x = 120
∴ x = 0° ∴ x = 120 - 60 = 60°
Therefore, the values are x = 0° or x = 60° i.e between 0° to 360°

Answer:
The average rate of speed of the model airplane, per second is 18 feet.
Step-by-step explanation:
Given:
It took the model airplane 5 seconds to go 90 feet.
Now, to find the average rate of speed in feet per second.
So, in 5 seconds the airplane go to = 90 feet.
In 1 second the airplane go to = 90 ÷ 5 feet.

Find two consecutive positive integers whose product is 552.
Answer:
The numbers are 23 and 24
Step-by-step explanation:
Let
x ----> the first positive consecutive integer
x+1 ----> the second positive consecutive integer
we know that
The product of the two consecutive positive integers is 552
so
The algebraic expression that represent this situation is
[tex]x(x+1)=552[/tex]
Convert to expanded form
[tex]x^2+x-552=0[/tex]
Solve the quadratic equation by graphing
The roots of the equation are
[tex]x_1=-24[/tex] ----> the number cannot be negative
[tex]x_2=23[/tex]
see the attached figure
therefore
[tex]x=23\\x+1=24[/tex]
The numbers are 23 and 24
To find two consecutive positive integers whose product is 552, set up the equation x(x + 1) = 552, expand and solve the quadratic equation.
Explanation:To find two consecutive positive integers whose product is 552, we can set up the equation x(x + 1) = 552, where x represents the smaller integer.
Expanding the equation, we get x^2 + x - 552 = 0. This is a quadratic equation, and we can solve it by factoring or using the quadratic formula.
Factoring the quadratic equation, we find that (x - 23)(x + 24) = 0. So the two consecutive positive integers are 23 and 24.

Lora, a campaign manager, distributes flyers to 35% of the homes in her community. Lora distributes flyers to 630 homes. How many homes are in her community?
To calculate the total number of homes in Lora's community, the number of flyers distributed (630) is divided by the percentage of homes that received flyers (35%), resulting in a total of 1800 homes.
To find the total number of homes in Lora's community, we need to set up a proportion where the number of flyers delivered represents 35% of all homes. Since Lora distributed flyers to 630, that is 35% of the total homes. Using the percentage formula:
Total Homes = Distributed Flyers / Percentage of Homes
So, in this case, it would be:
Total Homes = 630 / 0.35
Dividing 630 homes by 0.35 (35% as a decimal) gives us:
Total Homes = 1800
Therefore, there are 1800 homes in Lora's community.
