The exact length of the given curve is 62/3
We can calculate the above answer by following the steps given below,
We have been given the following values,
x = 1/3 √y (y - 3), 4 ≤ y ≤ 16
The curve is of the length, x = f(y) from y =a to y = b is given by:
x = 1/3 √y (y - 3)
x = 1/3 (- 3)
dx/dy = 1/3 [(3/2)- (3/2)]
= 1/3 [(3/2) - (3/2)]
= 1/2 [ - 1/]
= (y-1)/2√y = f'(y)
Now we will calculate the length of the curve
= [tex]\int\limits^a_b {\sqrt{1+f'(y)^{2} } } \, dy[/tex]
= [tex]\int\limits^a_b{\sqrt{1+ (\frac{y-1}{2\sqrt{y} } )^2} } \, dy[/tex] (here a= 4, b=16)
= [tex]\int\limits^{16} _4 {\sqrt{1+ (\frac{y^2+2y-1}{4y} } )^} } \, dy[/tex]
= [tex]\int\limits^{16} _4 {\sqrt{\frac{4y+ y^2+ 2y-1}{4y} } } \, dy[/tex]
= [tex]\int\limits^{16}_4 {\frac{y+1}{2\sqrt{y} } } \, dy[/tex]
= [tex]\int\limits^{16}_4 {\frac{1}{2}\sqrt{y} } \, dy+ \int\limits^{16}_4 {\frac{1}{2\sqrt{y} } } \, dy[/tex]
= [1/3 (64-8)] +[4-2]
= (56/3)+2
= 62/3
Therefore the exact length of the curve that we get after solving the equation for curve is x = 1/3, 4 ≤ y ≤ 16, is 62/3.

Rider and Caleb bought 5 gallons of juice for a classroom party. The cost was $25.55. What is the cost per pint of juice? (Round your answer to the nearest cent.)
The cost per pint of juice $0.63875.
What is division?
Division, or the process by which two or more numbers are joined together to generate a new number, is one of the four basic arithmetic operations. Addition, subtraction, and multiplication make up the remaining operations.
Weight of juice for a classroom party is 5 gallons.
Total price is $25.55.
We know that 1 US liquid pint = 0.125 US liquid Gallon
=> 0.125 US liquid Gallon = 1 US liquid pint
Therefore, 5 US liquid Gallon = 5/0.125 US liquid pint
=> 5 US liquid Gallon = 8*5 US liquid pint
=> 5 US liquid Gallon = 40 US liquid pint
Now, the required price is 25.55/40 = $0.63875
Hence, the cost per pint of juice $0.63875.

Suppose that the number of hours that it takes for a student to finish an inquiry has density
f(x) =
{ 2/5(x + 1) if 1 < x < 2
{ 0 otherwise.
a) Find the probability that the student finishes the inquiry in less than 1.5 hours.
b) Find the mean and standard deviation of the number of hours it takes to finish the inquiry.
The probability that the student finishes the inquiry in less than 1.5 hours is 0.45.
Mean= 4/3 and standard deviation= √(11/90)
a) To find the probability that the student finishes the inquiry in less than 1.5 hours, we need to find the area under the probability density function (PDF) of f(x) between the lower limit of 1 and the upper limit of 1.5.
This is given by the definite integral of f(x) from 1 to 1.5:
∫f(x)dx from 1 to 1.5
= ∫(2/5(x + 1))dx from 1 to 1.5
= (2/5)∫(x + 1)dx from 1 to 1.5
= (2/5)[x^2/2 + x] from 1 to 1.5
= (2/5)[(1.5)^2/2 + 1.5 - (1)^2/2 - 1]
= (2/5)[2.25/2 + 1.5 - 1/2 - 1]
=(2/5)[2.25/2]
=0.45
b) To find the mean, we need to use the formula:
Mean = ∫x*f(x)dx from a to b
In this case:
Mean = ∫x*(2/5(x + 1))dx from 1 to 2
= (2/5)∫x(x + 1)dx from 1 to 2
= (2/5)[x^3/3 + x^2/2] from 1 to 2
=(2/5)[(2)^3/3 + (2)^2/2 - (1)^3/3 - (1)^2/2]
= (2/5)[8/3 + 4/2 - 1/3 - 1/2]
=(2/5)[7/3 + 3/2]
=(2/5)[(20)/6]
=4/3
=1.333
To find the standard deviation, we need to use the formula:
Standard deviation^2 =(∫(x-μ)^2*f(x)dx) from a to b
Where μ is the mean
In this case,
Standard Deviation ^2= ∫(x-μ)^2(2/5)(x+1) dx from 1 to 2
=(2/5)∫(x-μ)^2(x+1) dx from 1 to 2
Simplifying, we get,
(x-μ)^3*(3x+μ+4)/30 from 1 to 2
=[(2-μ)^3*(6+μ+4)-(1-μ)^3*(3+μ+4)]/30
=[(2-μ)^3*(10+μ)-(1-μ)^3*(7+μ)]/30
Substituting the value of μ,
=[(2-4/3)^3*(10+4/3)-(1-4/3)^3*(7+4/3)]/30
=11/90
Therefore, Standard Deviation= √(11/90)

Solve for:
a)
b)
c)
d)
It's worth noting that to solve for T2 you need to have the values of other variables such as K1, K2, Ea, R and T1
What is the Arrhenius Equation?
The Arrhenius equation is a mathematical equation that describes the relationship between the rate constant (K) of a chemical reaction and the temperature (T) of the reaction. The equation was first proposed by Svante Arrhenius in 1889 and it states that the rate constant of a chemical reaction is directly proportional to the exponential of the negative activation energy (Ea) of the reaction, divided by the gas constant (R) and the absolute temperature (T). The equation can be written as:
K = A * e^(-Ea / (R*T))
The Arrhenius Equation Two-point form is a mathematical equation that describes the relationship between the rate constant (K) of a chemical reaction, the activation energy (Ea) of the reaction, the universal gas constant (R), and the temperature (T) of the reaction.
Given the equation K2/K1 = Ea / R (1/T1 - 1/T2)
a. To solve for K2, we can multiply both sides of the equation by
K1: K2 = K1 * Ea / R (1/T1 - 1/T2)
b. To solve for K1, we can divide both sides of the equation by
Ea / R (1/T1 - 1/T2): K1 = K2 / Ea / R (1/T1 - 1/T2)
c. To solve for Ea, we can multiply both sides of the equation by
R (1/T1 - 1/T2): Ea = K2/K1 * R (1/T1 - 1/T2)
d. To solve for T2, we can use the equation 1/T2= 1/T1 - Ea/R * K1/K2
It's worth noting that to solve for T2 you need to have the values of other variables such as K1, K2, Ea, R and T1.

Solve 6x - 7y= 18 for y
To solve the equation 6x - 7y = 18 for y, you can start by isolating y on one side of the equation. To do this, you can add 7y to both sides of the equation:
6x - 7y + 7y = 18 + 7y
6x = 18 + 7y
Next, divide both sides of the equation by 7:
6x/7 = 18/7 + 7y/7
x = 3 + y
So the solution is y = 3 - x
This is the final solution for y in the equation 6x - 7y = 18

Given:
ST=4x-4, TU=4x-10, and SU =5x+1
We have to find the numerical length of TU.
Here,
SU = ST + TU
5x + 1 = 4x - 4 + 4x - 10
Simplifying,
5x + 1 = 8x - 14
Subtract 1 on both sides,
5x + 1 - 1 = 8x - 14 - 1
5x = 8x - 15
Subtract 5x on both sides,
5x - 5x = 8x - 15 - 5x
0 = 3x - 15
3x = 15
x = 5
⇒ TU = 5(5) + 1 = 25 + 1 = 26

find the length of the curve. r(t) = 6t i + 8t3/2 j + 6t2 k, 0 ≤ t ≤ 1
The length of the curve is given by the integral of the magnitude of the velocity vector, which is the derivative of the position vector. Taking the derivative of the position vector, we get the velocity vector as follows:
v(t) = 6i + 24t1/2j + 12tk
The magnitude of this vector is
√(6²+ 24²t + 12²t²)
= √(36 + 576t + 144t²).
To find the length of the curve, we need to integrate this magnitude from t=0 to t=1. This is given by the integral:

Part AUse the coordinates to determine the function.
Point (0, 2):
2 = a*b⁰ ⇒ 2 = aThe function becomes:
y = 2bˣIt has a multiplier of 0.8, so b = 0.8, so the function is:
y = 2*0.8ˣPart BUse the first point:
3.5 = a*b⁰ ⇒ 3.5 = aUse the second point:
31.5 = 3.5*b²9 = b²b = √9b = 3The function is:
y = 3.5*3ˣAnswer:
[tex]\textsf{a)} \quad y=2(0.8)^x[/tex]
[tex]\text{b)} \quad y=3.5(3)^x[/tex]
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Function}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]
Question (a)Given:
y-intercept = (0, 2) ⇒ a = 2multiplier = 0.8 ⇒ b = 0.8Substitute the values of a and b into the exponential function formula:
[tex]\implies y=2(0.8)^x[/tex]
Question (b)The y-intercept is when x = 0. Therefore, given the function passes through point (0, 3.5), the y-intercept is 0.35 ⇒ a = 3.5.
Substitute the found value of a and given point (2, 31.5) into the exponential function formula and solve for b:
[tex]\implies 31.5=3.5b^2[/tex]
[tex]\implies b^2=9[/tex]
[tex]\implies b=3[/tex]
Substitute the values of a and b into the exponential function formula:
[tex]\implies y=3.5(3)^x[/tex]
