Answer:
7953.873
Step-by-step explanation:
The first derivative is ...
f'(x) = 4·3x²·e^x +4x³·e^x = e^x(4x³ +12x²)
Then the second derivative is ...
f''(x) = (12x² +24x)e^x +(4x³ +12x²)e^x
f''(x) = e^x(4x³ +24x² +24x)
So, f''(3) = (e^3)(4·27 +24·9 +24·3) = 396e^3 = 7953.87262158
Rounded to thousandths, this is ...
f''(3) = 7953.873
Answer:
f''(x) ≈ 7953.87

Basic Power Rule:
f(x) = cxⁿf’(x) = c·nxⁿ⁻¹Product Rule: [tex]\displaystyle \frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)[/tex]
Derivative Rule: [tex]\displaystyle \frac{d}{dx} [e^x]=e^x[/tex]
Step-by-step explanation:
Step 1: Define
f(x) = 4x³eˣ
f''(x) is x = 3 for 2nd Derivative
Step 2: Differentiate
[1st Derivative] Product Rule [Basic Power Rule]: f'(x) = 3 · 4x³⁻¹eˣ + 4x³eˣ[1st Derivative] Simplify: f'(x) = 12x²eˣ + 4x³eˣ[1st Derivative] Factor: f'(x) = eˣ(12x² + 4x³)[2nd Derivative] Product Rule [Basic Power Rule]: f''(x) = eˣ(12x² + 4x³) + eˣ(2 · 12x²⁻¹ + 3 · 4x³⁻¹)[2nd Derivative] Simplify: f''(x) = eˣ(12x² + 4x³) + eˣ(24x + 12x²)[2nd Derivative] Distribute eˣ: f''(x) = 12eˣx² + 4eˣx³ + 24eˣx + 12eˣx²[2nd Derivative] Combine like terms: f''(x) = 24eˣx² + 4eˣx³ + 24eˣx[2nd Derivative] Factor: f''(x) = 4xeˣ(x² + 6x + 6)Step 3: Evaluate
Substitute: f''(x) = 4(3)e³(3² + 6(3) + 6)Exponents: f''(x) = 12e³(9 + 6(3) + 6)Multiply: f''(x) = 12e³(9 + 18 + 6)Add: f''(x) = 12e³(27 + 6)Add: f''(x) = 12e³(33)Multiply: f''(x) = 396e³Evaluate: f''(x) ≈ 396(20.0855)Multiply: f''(x) ≈ 7953.8725X1/10 simplest form

19. Brian bought a new jacket at a discount of 30%. If the original price was $65, how much did Brian pay for the jacket?
Answer:45.5
Step-by-step explanation:
65•30%=19.5
65-19.5=45.5
Cost of the jacket with the discount is given by the equation A = $ 45.50
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of the jacket with the discount be A
Now , the equation will be
The cost of the jacket = $ 65
The discount percentage =30 %
So , the discount amount = ( 30/100 ) x 65
The discount amount = 0.3 x 65
The discount amount = $ 19.50
Now , the cost of the jacket with the discount A = cost of the jacket - discount amount
Substituting the values in the equation , we get
The cost of the jacket with the discount A = 65 - 19.50
The cost of the jacket with the discount A = $ 45.50
Hence , the cost is $ 45.50

Step-by-step explanation:
the rate of change between the first two pairs of x-and-y values is 12/3, between the second pair it is 21/3, and 15/3 between the last pair
4, 7, and 5 are all different values so there is not one constant of proportionality
Jim is 9 years older than June. Alex is 8 years younger than June. If the total of
their ages is 82, how old is the eldest of them?
Answer:
36 years old (jim)
Step-by-step explanation:
looks like a good ol' word problem!
first, if you don't know what to do, always assign variables
Jim's age: x+9
June's age: x
Alex's age: x-8
we know the sum of their ages which is 82
so, x+9+x+x-8=82
simplify
3x+1=82
3x=81
x=27, but we're not done yet
Now we know x
jim: 36
june: 27
Alex: 21
so the oldest is jim at 36

Find the missing side lengths leave your answers as radicals in simplest form
Answer:
14
Step-by-step explanation:
To find x, you will need to use sine. If you want to find y, use cosine:
sin 45 = x / 14 sqrt(2)
x = 14
(Since this is a 45 45 90 special triangle, x and y have the same length)
Since I talk about special triangles, 45 45 90 triangles are very simple:
To find the other two side lengths, just divide the hypotenuse by sqrt 2
14 sqrt(2) / sqrt(2) = 14
So both ways will still lead to 14

Answer:
There is an outlier because she was injured and could not run.
Step-by-step explanation:
There are several reasons why Cassie wouldn't have been able to run on Sunday, but a potential reason is because she had a minor injury that took her one day to heal. Because of her taking this day off, it creates an outlier in our table.
