Taking Derivatives with respect to x
Basic Power Rule:
f(x) = cxⁿ f’(x) = c·nxⁿ⁻¹Chain Rule: [tex]\displaystyle \frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)[/tex]
Step-by-step explanation:
Step 1: Define
Function: y = f(x), twice differentiable.
[tex]\displaystyle f(1) = 3\\\frac{dy}{dx} = (4y^2 + 7x^2)^{\frac{1}{2}}[/tex]
Step 2: Differentiate
Remember we are taking the derivative with respect to x.
Chain Rule [Basic Power Rule]: [tex]\displaystyle \frac{d^2y}{dx^2} = \frac{1}{2}(4y^2 + 7x^2)^{\frac{1}{2} - 1} \cdot \frac{dy}{dx} (4y^2 + 7x^2)[/tex][2nd Derivative] Simplify: [tex]\displaystyle \frac{d^2y}{dx^2} = \frac{1}{2}(4y^2 + 7x^2)^{-\frac{1}{2}} \cdot \frac{dy}{dx} (4y^2 + 7x^2)[/tex][2nd Derivative - Chain Rule] Basic Power Rule: [tex]\displaystyle \frac{d^2y}{dx^2} = \frac{1}{2}(4y^2 + 7x^2)^{-\frac{1}{2}} \cdot (0 + 2 \cdot 7x^{2 - 1})[/tex][2nd Derivative] Simplify: [tex]\displaystyle \frac{d^2y}{dx^2} = \frac{1}{2}(4y^2 + 7x^2)^{-\frac{1}{2}} \cdot 2 \cdot 7x[/tex][2nd Derivative] Simplify: [tex]\displaystyle \frac{d^2y}{dx^2} = \frac{7x}{\sqrt{7x^2 + 4y^2}}[/tex]Step 3: Evaluate
We are given x = 1 and f(1) = 3. This will tell us the instantaneous slope.
Substitute [2nd Deriv]: [tex]\displaystyle f''(1) = \frac{7(1)}{\sqrt{7(1)^2 + 4(3)^2}}[/tex][√Radical] Exponents: [tex]\displaystyle f''(1) = \frac{7(1)}{\sqrt{7(1) + 4(9)}}[/tex][Fraction] Multiply: [tex]\displaystyle f''(1) = \frac{7}{\sqrt{7 + 36}}[/tex][√Radical] Add: [tex]\displaystyle f''(1) = \frac{7}{\sqrt{43}}[/tex]This tells us that the rate of change of the slope of the tangent line is [tex]\displaystyle \frac{7}{\sqrt{43}}[/tex].
We can also write an equation for the instantaneous slope:
[Equation] [tex]\displaystyle y - 3 = \frac{7}{\sqrt{43}}(x - 1)[/tex]

What is the slope of the line represented by the equation y = 4/5x-3
Answer:
slope = [tex]\frac{4}{5}[/tex]
Step-by-step explanation:
The equation [tex]y = \frac{4}{5} x -3[/tex] is already written in slope-intercept form, or [tex]y = mx + b[/tex]. In this form, the number in place of the [tex]m[/tex] represents the slope. In this equation, the [tex]\frac{4}{5}[/tex] takes the place of that [tex]m[/tex], so the slope would be [tex]\frac{4}{5}[/tex].

Answer:
y= 38x
Step-by-step explanation:
It is going up by 38 each time. There is no b value (y=mx + b), because if you times 6 by 38, you get 228. You don't need to add any remainders.

Find x & y so that quadrilateral is a parallelogram. (Look at image)
Answer:
x = 5° y = 75
Step-by-step explanation:
Here given it is a quadrilateral
105° + y = 180° ( being co-interior angles)
y = 180° - 105°
y = 75°
Now
15x + 105° = 180° (being co-interior angles)
15x = 180° - 105°
15x = 75°
x = 75° / 15
x = 5°
Hope it will help :)❤

Why is 2x 3/4 less than 2?
Answer & Step-by-step explanation:
It is less because 2 times 3/4 is the same as 2/1 times 3/4 which is 6/4 then simplify it and you get 3/2 which then is 1 1/2.
That is why 2 times 3/4 is less than 2.
Hope that helps ;)

(-3, 0) to polar form.
9514 1404 393
Answer:
(3; 180°)
Step-by-step explanation:
The point (-3, 0) is located on the -x axis at a distance of 3 units from the origin. The -x axis is at an angle of 180° CCW from the +x axis. So, the polar coordinates are ...
r = 3
θ = 180°
This might be written as ...
(r; θ) = (3; 180°) = (3; π radians)

Answer:
93.69 Ft for fencing
Explanation:
So first find the perimeter for the rectangle (what is exposed)
SO its 17+25+25=67
Now we need to find the Circumference of the circle (perimeter of circle)
SO circumference formula is just
π*d
So in this case 17 *3.14 is 53.38
53.38 is the full Circumfrnce but divide that by 2 due to the circle being only half exposed
53.38/2=26.69
Now 26.69+67= 93.69 ft
For perimeter
Answer:
soit should angle + angle
Step-by-step explanation:
because what number they are you have to add both of the first numbers then you have too add the second two times

A small pot holds 25% as much dirt as a large pot. If the small pot holds 8 cups of dirt, How many cups of dirt does the large pot hold
Given :
A small pot holds 25% as much dirt as a large pot.
To Find :
If the small pot holds 8 cups of dirt, How many cups of dirt does the large pot hold.
Solution :
It is given that small pot holds 25% as much as dirt.
It means that large pot can hold 4 times as small pot.
Let, large pot holds x cups of dirt.
[tex]x = 4\times 8\\\\x = 32 \ cups[/tex]
Therefore, large pot holds 32 cups.

The IRS was interested in the number of individual tax forms prepared by small accounting firms. The IRS randomly sampled 50 public accounting firms with 10 or fewer employees in the Dallas-Fort Worth area. The following frequency table reports the results of the study.
Number of Clients Frequency
25 up to 40 3
40 up to 55 11
55 up to 70 24
70 up to 85 8
85 up to 100 4
Estimate the mean and the standard deviation. Round squared deviations to the nearest whole number and the final answer to 2 decimal places.
Answer:
Estimates of the number of individual tax forms prepared by small accounting firms:
1. Mean = 10
2. Standard deviation = 7.56
Step-by-step explanation:
a) Data and Calculations:
Number of Clients Frequency Mean Diff Squared Deviation
25 up to 40 3 -7 49
40 up to 55 11 1 1
55 up to 70 24 14 196
70 up to 85 8 -2 4
85 up to 100 4 -6 36
Sum 50 286
Mean of frequencies = 10 (50/5) 57.2 (286/5)
Standard deviation = square root of 57.2 = 7.56
b) The IRS can obtain the mean value of the number of individual tax forms prepared by small accounting firms by dividing the sum of the frequencies by the numbers (50/5). Similarly, the IRS can calculate the standard deviation of the number of individual tax forms prepared by small accounting firms, which measures how spread out the data is about the mean value, by working out the mean of the frequency numbers. Then subtract the mean for each number and square each result. Add up the squared differences and divide by the number to get the mean. Finally, take the square root of the mean differences.
