The estimated value of f(0.98,3.08) is 5.358
To find the differential of[tex]f(x,y) = \sqrt{(x^2 + y^3)}[/tex], we can use the formula for the differential:
df = (∂f/∂x) dx + (∂f/∂y) dy
where dx and dy are small changes in x and y, respectively.
Taking the partial derivatives of f(x,y) with respect to x and y, we have:
∂f/∂x = [tex]x\sqrt{(x^2 + y^3)}[/tex]
∂f/∂y = [tex](3/2)y^(1/3) / \sqrt{(x^2 + y^3)}[/tex]
Substituting x = 1 and y = 3, we get:
∂f/∂x (1,3) = 1/√28
∂f/∂y (1,3) = (3/2)(3(1/3))/√28
So the differential of f(x,y) at (1,3) is:
df = (1/√28) dx + (3/2)(3(1/3))/√28 dy
To estimate f(0.98,3.08), we need to find the values of dx and dy that correspond to a small change in x and y from (1,3) to (0.98,3.08). We have:
dx = 0.98 - 1 = -0.02
dy = 3.08 - 3 = 0.08
Substituting these values into the differential, we get:
df ≈ (1/√28) (-0.02) + (3/2)(3(1/3))/√28 (0.08)
≈ 0.0187
f(0.98,3.08) ≈ f(1,3) + df
≈ √28 + 0.0187
≈ 5.358

What is horizontal line test answer?
The horizontal line test is a method used in mathematics to determine if a given function is one-to-one. A function is one-to-one if for every unique x-value, there is a unique y-value.
The horizontal line test is used to determine if a function is one-to-one by drawing a horizontal line through the graph of the function and seeing if the line intersects the graph at most once.
The horizontal line test is based on the idea that if a horizontal line intersects the graph of a function more than once, then there must be at least one pair of x-values that correspond to the same y-value.
This means that the function is not one-to-one and therefore, not invertible. A function that is not invertible is not a function in strict mathematical sense.
It's important to note that the horizontal line test can only be applied to functions that are defined on a closed interval or on all real numbers.
Also, It is only a sufficient condition, meaning that a function that passes the horizontal line test is one-to-one, but not all one-to-one function pass the horizontal line test.
In conclusion, the horizontal line test is a method used to determine if a given function is one-to-one by drawing a horizontal line through the graph of the function and seeing if the line intersects the graph at most once.
If it does, the function is one-to-one, if not, the function is not one-to-one and therefore not invertible. The test is only sufficient and should be used with caution.

The line passes through the origin, therefore one point on the line is sufficient to determine the equation:
y = kx, is the form of this equationThe point on the line is (1, - 3), so the line is:

Rachna ha nickel, dime, and quarter in her piggy bank. She ha $4. 65 altogether. She ha three more quarter han dime and twice a mahy nickel a quarter. How many quarter doe Rachna have?
Rachel has 0.41 quarters that can be obtained using the equation Q + D + N = T.
We can start by using the following equation to find the number of quarters Rachel has: Q + D + N = T
Where Q is the number of quarters, D is the number of dimes, N is the number of nickels, and T is the total amount of money in dollars. We know that T is $4.65, and we know that Rachel has twice as many nickels as quarters, and three more quarters than dimes.
Let's assume that Rachel has x number of quarters
So we can write the above equation as:
x + (x+3) + 2x = 4.65
4x+3 = 4.65
4x = 1.65
x = 0.4125
Rachel has 0.4125 quarters, Which is not possible as it is a decimal. So we need to round it off to the nearest whole number.
Rachel has 0.4125 quarters which is equivalent to o.41 quarters.
Therefore, Rachel has 0.41 quarters that can be obtained using the equation Q + D + N = T.

The perimeter of a rectangle is 172 feet. Find the length and width if the length is an integer and the width is 2 times the next consecutive integer.
The length of the rectangle is 28 feet, and the width is 58 feet.
How to find the length and width of the rectangle?We know that for a rectangle of length L and width W, the perimeter can be written as:
P = 2*(L + W)
Here we know that the perimeter is 172 ft, then we can write:
172 ft = 2*(L + W)
And we know that the length is an integer:
L = x
And the width is two times the next integer:
W = 2*(x + 1)
Then we can replace these two in the perimeter equation so we get:
172 = 2*(x + 2*(x + 1))
172 = 2*(x + 2x + 2)
172 = 6x + 4
172 - 4 = 6x
168 = 6x
168/6 = x
28 = x

In Ms. Rickets’ math class, students made a “polygon path” that consists of regular polygons of 3, 4, 5, and 6 sides joined together as shown.
All the angles from the polygon path made by the students are;
∠1 = 96°
∠2 = 90°
∠3 = 162°
∠4 = 132°
∠5 = 60°
How up illustrate the polygon?The images of the polygon are missing and so i have attached them. From the attached image, we can see we have;
Triangle (3-sided polygon)
Square (4-sided polygon)
Pentagon (5-sided polygon)
Hexagon (6 sided polygon)
Now, we know that formula for external angle of a polygon with n sides is 360/n.
Thus, for the 6-sided polygon, the ∠5 = 360/6
∠5 = 60°
Since ∠4 is shared by the pentagon and hexagon, then;
∠4 = (360/5) + 60
∠4 = 72° + 60°
∠4 = 132°
Since ∠3 is shared by the square and pentagon, then;
∠3 = 90 + 72
∠3 = 162°
∠2 = 90° because external angles of a square = 360/4 = 90°

At noon, a tank contains 5 in of water. After several hours, it contained 3 in of water. What is the percent decrease of water in the tank?
Answer: To calculate the percent decrease of water in the tank, we can use the following formula:
Percent decrease = (Initial value - Final value) / Initial value x 100%
In this case, the initial value of water in the tank is 5 inches and the final value is 3 inches. So, the percent decrease is:
(5 - 3) / 5 x 100% = 2 / 5 x 100% = 40%
So, the percent decrease of water in the tank is 40%.

O The distribution is bell shaped.
O The distribution is skewed right.
O The distribution is uniform.
O The distribution is skewed left.
The distribution of the data is skewed right, which means that the data is not evenly distributed across the range of values.
To calculate the skewness, we can use the formula Skewness = (Mean - Mode) / Standard Deviation. In this case, the mean is 599.2 seconds, the mode is 590 seconds, and the standard deviation is 110.88 seconds. Plugging these values into the formula, we get Skewness = (599.2 - 590) / 110.88 = 0.8094. This indicates that the data is skewed right, as the skewness is greater than 0. A right-skewed distribution typically occurs when the majority of data points are closer to the minimum value, while there are fewer data points near the maximum value.

Jerry tarted doing it-up every day. The firt day he did 15 it-up. Every day after that he did 2 more it-up than he had done the previou day. Today Jerry did 33 it-up. Write an equation that could be olved to find the number of day Jerry ha been doing it-up, not counting the firt day
Jerry has been doing it-up for number of 10 days , not counting the first day.
n + 14 = 33
n = 19 days
We know that Jerry did 15 it-up on the first day and 33 it-up today. Therefore, we can subtract 15 from 33 to get the total number of it-up that Jerry did over the past few days.
33 - 15 = 18e
We know that Jerry did 2 more it-up each day, so we can divide 18 by 2 to get the number of days.
18 / 2 = 9
Finally, we need to add 1 to the result to account for the first day.
9 + 1 = 10 days
Jerry has been doing it-up for 10 days, not counting the first day.

a Ferris wheel has a radius of 65 ft what is the circumference of the circle ( this would be the distance traveled by a passenger in one full rotation of the Ferris wheel use pi equals 3
never mind it equals 390 ft because C= 2 x 3 x 65 witch equals 390 ft
The circumference of the Ferris is 408.2 ft.
What is the circumference?We know that the circumference can be described as the distance round the circle. We have to note that the radius of the feriis would be very important as we try to obtain the circumference of the ferris.
We can see that the radius of the Ferris as is clear from the question that we have here is 65 ft. When the circumference can be gotten from the use of;
C = 2πr
Where r = radius and C = circumference
Thus;
C = 2 * 3.14 * 65
C = 408.2 ft
