[tex]\( f(2) = \ln \left( \frac{14}{3} \right) \)[/tex]. You can calculate this value to get a numerical result.
To find the particular solution [tex]\( y = f(x) \)[/tex] to the given differential equation [tex]\( \frac{dy}{dx} = \frac{x^2 + 1}{e^y} \)[/tex] with the initial condition [tex]\( f(1) = 0 \)[/tex] and then evaluate [tex]\( f(2) \),[/tex] we can follow these steps:
1. Separate variables:
[tex]\[ e^y dy = (x^2 + 1) dx \][/tex]
2. Integrate both sides:
[tex]\[ \int e^y dy = \int (x^2 + 1) dx \][/tex]
[tex]\[ e^y = \frac{1}{3} x^3 + x + C \][/tex]
3. Apply the initial condition [tex]\( f(1) = 0 \):[/tex]
[tex]\[ e^0 = \frac{1}{3} (1)^3 + 1 + C \][/tex]
[tex]\[ 1 = \frac{1}{3} + 1 + C \][/tex]
[tex]\[ C = \frac{2}{3} \][/tex]
So, the particular solution is:
[tex]\[ e^y = \frac{1}{3} x^3 + x + \frac{2}{3} \][/tex]
4. Solve for y :
[tex]\[ y = \ln \left( \frac{1}{3} x^3 + x + \frac{2}{3} \right) \][/tex]
Now, we need to find f(2), which means finding the value of y when x = 2:
[tex]\[ y = \ln \left( \frac{1}{3} (2)^3 + 2 + \frac{2}{3} \right) \][/tex]
[tex]\[ y = \ln \left( \frac{8}{3} + 2 + \frac{2}{3} \right) \][/tex]
[tex]\[ y = \ln \left( \frac{14}{3} \right) \][/tex]
use the fact that 2 1/2 divided by 1/8 equals 20 to find 2 1/2 divided by 5/8.
Answer:
The value of the expression is 4.
Step-by-step explanation:
Consider the provided information.
We have given that:
[tex]\dfrac{2\dfrac{1}{2} }{\dfrac{1}{8} } =20[/tex]
Now we need to find the value of:
[tex]\dfrac{2\dfrac{1}{2} }{\dfrac{5}{8} } =?[/tex]
Consider the provided fact:
[tex]\dfrac{2\dfrac{1}{2} }{\dfrac{1}{8} } =20[/tex]
Multiply [tex]\frac{1}{5}[/tex] both sides.
[tex]\dfrac{1}{5}\times \dfrac{2\dfrac{1}{2} }{\dfrac{1}{8} } =20\times\dfrac{1}{5}[/tex]
[tex]\dfrac{1\times2\dfrac{1}{2} }{5\times\dfrac{1}{8} } =20\times\dfrac{1}{5}[/tex]
[tex]\dfrac{2\dfrac{1}{2} }{\dfrac{5}{8} } =4[/tex]
Hence, the value of the expression is 4.

4 times a number divided by 3 is 5 more than that number divided by 2 what is the value of that number
Answer:
x=6
Step-by-step explanation:
Let the number be x
Then 4 times a number divided by 3 is 5 more than that number divided by 2 gives the equation:
[tex] \frac{4x}{3} = \frac{x}{2} + 5[/tex]
Multiply through by the LCD, which is 6.
[tex] 6 \times \frac{4x}{3} = 6 \times \frac{x}{2} + 5 \times 6[/tex]
Cancel out to obtain:
[tex] 2 \times 4x =3 \times x + 30[/tex]
[tex]8x = 3x + 30[/tex]
Group similar terms
[tex]8x - 3x = 30[/tex]
Simplify the LHS
[tex]5x = 30[/tex]
Divide both sides by 5 to get:
[tex]x = 6[/tex]
can you graph 6=6? infinite solutions
Answer:6 = 6 represents a true statement because 6 is always equal to 6. When graphed on a coordinate plane, this equation would result in a straight line at y = 6, which means that every point on the line corresponds to a solution of the equation. Since the line extends infinitely in both directions, there are infinitely many solutions to this equation.
Step-by-step explanation:
Identify the x intercept and y intercept of the line 2x-4y=-12
The x-Intercepts of the line 2x - 4y = -12 is -6 and the y-intercept is 3.
To identify the x and y intercepts of the line, we set one variable to zero and solve the equation for the other variable.
For the x-intercept, we set y=0 and solve for x in the equation: 2x - 4(0) = -12, hence x = -6.
For the y-intercept, set x=0 and solve for y in the equation: 2(0) - 4y = -12, hence y = 3.
Therefore, the x-intercept is -6 and the y-intercept is 3

Use the drawing tools to form the correct answers on the graph. Plot the zeros of this function: f(x) = (x – 1)(x – 7).
The answer is in the graph picture
The zeros of the function f(x) = (x - 1)(x - 7) are 1 and 7
The function is given as:
f(x) = (x - 1)(x - 7)
Set the function to 0.
So, we have:
f(x) = (x - 1)(x - 7) = 0
This gives
(x - 1)(x - 7) = 0
Split
(x - 1) = 0 or (x - 7) = 0
Remove brackets
x - 1 = 0 or x - 7 = 0
Solve for x
x = 1 or x = 7
Hence, the zeros of the function are 1 and 7

What is the prime factorization of 40?
2 times 5
2 times 20
2 times 2 times 2 times 5
2 times 2 times 4 times 5
Answer:
C.
Step-by-step explanation:
2 times 2 times 2 times 5 = 40
The prime factorization of 40 is 2 times 2 times 2 times 5, which can be written as 2^3 * 5. So, option C, "2 times 2 times 2 times 5," is the correct prime factorization of 40.
The prime factorization of the number 40 is 2^3 * 5. To arrive at this factorization, we break down 40 into its prime factors. We start by dividing 40 by the smallest prime number, 2. Since 40 is even, it can be divided by 2 evenly, resulting in 20. We continue this process until we can no longer divide by 2, which leaves us with 20. Now, we try to divide 20 by the next smallest prime, which is also 2. This division gives us 10. Once again, we divide by 2, and we are left with 5. Since 5 is a prime number, we cannot further divide it. Therefore, we have prime factorized 40 as 2 * 2 * 2 * 5, which can be expressed as 2^3 * 5, where the exponent 3 indicates that we have three 2s multiplied together, and the 5 is the prime factor on its own.

A pen in the shape of an isosceles right triangle with legs of length x ft and hypotenuse of length h ft is to be built. If fencing costs $ 4 divided by ft for the legs and $ 16 divided by ft for the hypotenuse, write the total cost C of construction as a function of h.
Answer:
[tex]\frac{8h}{\sqrt{2}} + 16h[/tex]
Step-by-step explanation:
First we need to compute the side length as a function of h
So x be the side length of the right isosceles triangle, in Pythagorean formula we have
[tex]x^2 + x^2 = h^2[/tex]
[tex]2x^2 = h^2[/tex]
[tex]x = \frac{h}{\sqrt{2}}[/tex]
The cost for the legs is
[tex]C_l = 4*2x = \frac{8h}{\sqrt{2}}[/tex]
The cost for the hypotenuse is
[tex]C_h = 16h[/tex]
So the total cost in term of h is
[tex]C = C_l + C_h = \frac{8h}{\sqrt{2}} + 16h[/tex]
The total cost C of construction as a function of h is C = 16 / h + 8√2 / h
The pen is in the shape of an isosceles right angle. This means one of the
angle is 90 degrees and 2 sides of the triangle are equal and the base angles
are equal too.
Using pythagora's theorem
Therefore,
x² + x² = h²
2x² = h²
x² = h² / 2
x = √h²/ √2 = h/√2
cost of the legs = 4 / h/√2 + 4 / h /√2 = 8√2 / h
cost of the hypotenuse = 16 / h
Total cost = 16 / h + 8√2 / h
C = 16 / h + 8√2 / h

Sarai is mixing a solution. She pours all the liquid from a full small beaker into a larger beaker. The liquid fills the large beaker to 15% of its capacity. If the small beaker holds 300 mL, how much does the large beaker hold?
Answer:
2000 ml
Step-by-step explanation:
Given: Sarai pours all the liquid from a full small beaker into a larger beaker.
The liquid fills the large beaker to 15% of its capacity.
The small beaker holds 300 ml.
Lets assume capacity of large beaker to hold be "x".
As given, Sarai pours all the liquid from a full small beaker into a larger beaker
∴ [tex]15\% \times x= 300\ ml[/tex]
⇒ [tex]0.15x= 300[/tex]
Dividing both side by 0.15
⇒[tex]x= \frac{300}{0.15}[/tex]
∴ [tex]x= 2000\ ml[/tex]
Hence, the large beaker can hold 2000 ml of liquid.

Make an x and y table, and pick any values to plug in for x in the equation.
I will use the numbers from -2 to 2
Now plug in the values you picked for x into the equation to find its y-value
x = -2
y = 3x - 1 Plug in -2 for x
y = 3(-2) - 1
y = -6 - 1
y = -7
x = -1
y = 3x - 1
y = 3(-1) - 1
y = -3 - 1
y = -4

The graph of which function has a minimum located at (4, –3)?
f(x) = one-halfx2 + 4x – 11
f(x) = –2x2 + 16x – 35
f(x) = one-halfx2 – 4x + 5
f(x) = 2x2 – 16x + 35
Answer:
f(x) = 1/2x^2 – 4x + 5 (the third option)
Step-by-step explanation:
I looked it up on a graphing calculator.
The quadratic function that has a minimum located at (4, -3) is:
[tex]f(x) = (1/2)*x^2 - 4x + 5[/tex]
Which function has a minimum located at (4, -3)?All the options are quadratic functions, so we need to find the one with a leading coefficient positive, which also has a vertex at (4, -3).
The 3 ones with positive leading coefficients are:
[tex]f(x) = (1/2)*x^2 + 4x -11[/tex]
[tex]f(x) = (1/2)*x^2 - 4x + 5[/tex]
[tex]f(x) = 2x^2 - 16x + 35[/tex]
The vertex of the first one is at:
[tex]x = -4/(2*1/2) = -4[/tex]
The x-value of the vertex must be x = 4, so we can discard this.
For the second quadratic function the x-value of the vertex is:
[tex]x = -(-4)/(2*1/2) = 4[/tex]
Then the y-value of the vertex is:
[tex]f(4) = (1/2)*4^2 - 4*4 + 5 = -3[/tex]
Then the vertex is at (4, -3), so this is the correct option.
