Answer:
[tex]f''(x)=36x^2+4[/tex]
Step-by-step explanation:
Let's start by finding the first derivative of [tex]f(x)= 3x^4+2x^2-8x+4[/tex]. We can do so by using the power rule for derivatives.
The power rule states that:
[tex]\frac{d}{dx} (x^n) = n \times x^n^-^1[/tex]This means that if you are taking the derivative of a function with powers, you can bring the power down and multiply it with the coefficient, then reduce the power by 1.
Another rule that we need to note is that the derivative of a constant is 0.
Let's apply the power rule to the function f(x).
[tex]\frac{d}{dx} (3x^4+2x^2-8x+4)[/tex]Bring the exponent down and multiply it with the coefficient. Then, reduce the power by 1.
[tex]\frac{d}{dx} (3x^4+2x^2-8x+4) = ((4)3x^4^-^1+(2)2x^2^-^1-(1)8x^1^-^1+(0)4)[/tex]Simplify the equation.
[tex]\frac{d}{dx} (3x^4+2x^2-8x+4) = (12x^3+4x^1-8x^0+0)[/tex] [tex]\frac{d}{dx} (3x^4+2x^2-8x+4) = (12x^3+4x-8(1)+0)[/tex] [tex]\frac{d}{dx} (3x^4+2x^2-8x+4) = (12x^3+4x-8)[/tex][tex]f'(x)=12x^3+4x-8[/tex]Now, this is only the first derivative of the function f(x). Let's find the second derivative by applying the power rule once again, but this time to the first derivative, f'(x).
[tex]\frac{d}{d} (f'x) = \frac{d}{dx} (12x^3+4x-8)[/tex] [tex]\frac{d}{dx} (12x^3+4x-8) = ((3)12x^3^-^1 + (1)4x^1^-^1 - (0)8)[/tex]Simplify the equation.
[tex]\frac{d}{dx} (12x^3+4x-8) = (36x^2 + 4x^0 - 0)[/tex] [tex]\frac{d}{dx} (12x^3+4x-8) = (36x^2 + 4(1) - 0)[/tex] [tex]\frac{d}{dx} (12x^3+4x-8) = (36x^2 + 4 )[/tex]Therefore, this is the 2nd derivative of the function f(x).
We can say that: [tex]f''(x)=36x^2+4[/tex]
Answer:
[tex]y = f(x) = 3 {x}^{4} + 2 {x}^{2} - 8x + 4 \\ \frac{dy}{dx} = 12 {x}^{3} + 4x - 8 \\ \frac{d {}^{2} y}{dx {}^{2} } = 36 {x}^{2} + 4 \\ \boxed{\frac{d {}^{2} y}{dx {}^{2} } = 4(9 {x}^{2} + 1)}[/tex]

The volume of a cone is 1/3 that of a cylinder when the radius and height are the same (v= 1/3(pi)(r)^2(h). What is the volume of a cone with a radius of 10 inches and a height of 12 inches.
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Surface Areas and Volumes.
Since, Volume of cone = 1/3 π r^2 h,
here, r = 10 Inches and h= 12 inches, also π =3.14
so, VOC = 1/3 π (10)^2 × (20)
VOC = 1/3(3.14)(100)(20)= 2093.33 inch^3
=> so the volume of the cone is 2093.33 cubic inches.

Let f(x) = 2x2 + x − 3 and g(x) = x − 1. Find f(x) • g(x).
Answer:
Simply place the f(x) polynomial over g(x) to get the f(x) / g(x) result. Since polynomials have an infinite domain, the only gap you will get comes from the denominator equaling zero. That happens when:
X - 1 = 0
+1 +1
X = 1
So the domain is: D: X≠ 1

Answer:
2x + 3y = -13
Step-by-step explanation:
We can first find the equation of the line in point-slope form. The slope of the line is given by [tex](y_2-y_1)/(x_2-x_1)[/tex], which is (-5-(-3))/(1-(-2)), or -2/3. The equation for a line in point-slope form is [tex]y-y_1=m(x-x_1)[/tex] where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex] is a point on the line -- in this case, we may use (1, -5). Therefore, the equation for the line is y + 5 = -2/3 (x-1).
The question asks for the equation of the line in standard form -- which is [tex]Ax+By=C[/tex]. We can get this by simplifying the equation above to get[tex]2x+3y=-13[/tex].

Car Sales A manufacturer of economy cars has determined that 50,000 cars per month can be sold at a price of $18,000 per car. At a price of $17,500, the number of cars sold per month would increase to 55,000. Determine a linear function that predicts the number of cars that will be sold at a price of x dollars. Use this model to predict the number of cars that will be sold at a price of $17,000.
Answer: 60,000 cars would be sold at $17000.
Step-by-step explanation:
• first we find the slope of the function between two points
(50,000, 18000) and ( 55,000, 17500)
• Let the number of cars sold be the x axis coordinate.
and the price is the y axis coordinate.
• next we plot this points.
m= Change in y / Change in x = rise / run
The slope m = (18000 - 17500/ 50,000 - 55,000)
= -0.1
• The equation of the line in point slope form is m(x-x1)=(y-y1)
• substituting for the first point
-0.1 (X-50,000) = y-18000
-0.1x - 5000 = y - 18000
-0.1x = 18000 + 5000
y = -0.1x + 23000
our slope -0.1 is negative.
In order to find the number of cars to be sold at a price of $17000, substitute this value y in the equation such that:
17000 =-0.1x+23000
solve for x
-0.1x = 23000-17000
0.1x = 6000
divide both sides by 0.1
x = 60000
60,000 cars would be sold at $17,000

other side (a) 7cm (b) 9cm (c) 13cm 76
2.
Answer:
(a)
Step-by-step explanation:
since a parallelogram has atleast 2 equal sides, we take the 12cm and double it. That equals 24cm. So, 38cm take away 24cm equals 14cm. And since a parallelogram has 4 sides we half 14cm, which gives us 7cm.

What is mZSVT?
Enter your answer in the box.
Answer:
The measure of ∠SVT is 79°
Step-by-step explanation:
In the given figure
∵ US ∩ RT at V
∴ ∠SVT and ∠UVR are vertically opposite angles
∵ The vertically opposite angles are equal in measures
∴ m∠SVT = m∠UVR
∵ m∠SVT = (5y + 9)°
∵ m∠UVR = (8y - 33)°
→ Equate them
∴ 8y - 33 = 5y + 9
→ Add 33 to both sides
∴ 8y - 33 + 33 = 5y + 9 + 33
∴ 8y = 5y + 42
→ Subtract 5y from both sides
∴ 8y - 5y = 5y - 5y + 42
∴ 3y = 42
→ Divide both sides by 3
∵ [tex]\frac{3y}{3}[/tex] = [tex]\frac{42}{3}[/tex]
∴ y = 14
→ Substitute the value of y in the measure of ∠SVT
∵ m∠SVT = 5(14) + 9
∴ m∠SVT = 70 + 9
∴ m∠SVT = 79°
∴ The measure of ∠SVT is 79°
