We have this equation, logarithm base 10 of x, which is equal to y.
This equation can be reorganized like this: \(10^{y}\) = x, or 10 to the y power is equal to x.
y represents the power that 10 (the base) is raised to, while x represents the result of \(10^{y}\) (the base to the power of y).

Find an equation for the circle of curvature of the curve r(t) = t i + sin(5t) j at the point [π/2, 1].(The curve parameterizes the graph of y = sin (5x) in the xy-plane.)
Choose the correct equation for the circle of curvature.
a. [x - π/2]^2 + (y - 1)^2 = 1/625
b. [x - π/2]^2 + [y - 24/25]^2 = 1/625
c. [x - π/2]^2 + (y - 1)^2 = 625
d. [x - π/2]^2 + (y - 26/25)^2 = 625
The correct equation for the circle of curvature.
\(a. [x - \pi /2]^2 + (y - 1)^2 = 1/625\)
To find the equation for the circle of curvature of the curve, we need to determine the center and radius of the circle. The circle of curvature is the locus of the centers of the osculating circles of the curve at various points.
The curvature of a curve r(t) = x(t) i + y(t) j is given by the formula:
\(K(t) = |(x'(t)y''(t) - y'(t)x''(t)) / [(x'(t)^2 + y'(t)^2)^{3/2})|\)
where prime denotes the derivative with respect to t.
First, let's find the derivatives of the given curve:
r(t) = t i + sin(5t) j
r'(t) = 1 i + 5cos(5t) j
r''(t) = -25sin(5t) i
x(t) = t
x'(t) = 1
y(t) = sin(5t)
y'(t) = 5cos(5t)
y''(t) = -25sin(5t)
Now, let's evaluate these derivatives at t = π/2:
x'(π/2) = 1
y'(π/2) = 5cos(π/2) = 5(0) = 0
x''(π/2) = 0
y''(π/2) = -25sin(π/2) = -25
Substituting these values into the curvature formula:
\(K(\pi /2) = |(1)(-25) - (0)(0) / [(1^2 + 0^2)^{3/2}]|\\= |-25 / 1^{3/2}|\\= 25\)
The radius of curvature (ρ) is the reciprocal of the curvature:
ρ = 1 / κ(π/2)
= 1 / |-25|
= 1/25
The center of the circle of curvature lies on the normal line to the curve at the point [π/2, 1].
The normal line is perpendicular to the tangent line, which has the direction vector given by r'(π/2) = 1 i + 0 j = i.
The normal line passing through the point [π/2, 1] is given by the equation:
r(t) = [π/2, 1] + t i
The center of the circle lies on this line, so we can express it as:
C = [π/2, 1] + t i
To find t, we substitute the point [π/2, 1] into the equation of the line:
[π/2, 1] = [π/2, 1] + t i
This implies t = 0.
Therefore, the center of the circle is C = [π/2, 1].
Now, we have the center and radius of the circle, so we can write its equation in the form:
\([(x - \pi /2)^2 + (y - 1)^2] = (1/radius of curvature)^2\\[(x - \pi /2)^2 + (y - 1)^2] = (1/25)^2\\[(x - \pi /2)^2 + (y - 1)^2] = 1/625\)

By multiplying 5/3^4 by _________, we get 5^4
The missing Value, x, that when multiplied by 5/3^4 gives the result of 5^4 is 13125.
The missing value that, when multiplied by 5/3^4, gives the result of 5^4, we can set up the equation:
(5/3^4) * x = 5^4
To solve for x, we can simplify both sides of the equation. First, let's simplify the right side:
5^4 = 5 * 5 * 5 * 5 = 625
Now, let's simplify the left side:
5/3^4 = 5/(3 * 3 * 3 * 3) = 5/81
Now we have:
(5/81) * x = 625
To solve for x, we can multiply both sides of the equation by the reciprocal of 5/81, which is 81/5:
(81/5) * (5/81) * x = (81/5) * 625
On the left side, the fraction (81/5) * (5/81) simplifies to 1, leaving us with:
1 * x = (81/5) * 625
Simplifying the right side:
(81/5) * 625 = 13125
Therefore, the missing value, x, that when multiplied by 5/3^4 gives the result of 5^4 is 13125.

Molly's school is selling tickets to a play. On the first day of ticket sales the school sold 7 senior citizen tickets and 11 student tickets for a total of $125. The school took in $180 on the second day by selling 14 senior citizen tickets and 8 student tickets. What is the price each of one senior citizen ticket and one student ticket?
Answer: the price of one senior citizen ticket is $10, and the price of one student ticket is $5.
Step-by-step explanation:
Let's assume the price of one senior citizen ticket is 's' dollars and the price of one student ticket is 't' dollars.
According to the given information, on the first day, the school sold 7 senior citizen tickets and 11 student tickets, totaling $125. This can be expressed as the equation:
7s + 11t = 125 ---(1)
On the second day, the school sold 14 senior citizen tickets and 8 student tickets, totaling $180. This can be expressed as the equation:
14s + 8t = 180 ---(2)
We now have a system of two equations with two variables. We can solve this system to find the values of 's' and 't'.
Multiplying equation (1) by 8 and equation (2) by 11, we get:
56s + 88t = 1000 ---(3)
154s + 88t = 1980 ---(4)
Subtracting equation (3) from equation (4) eliminates 't':
(154s + 88t) - (56s + 88t) = 1980 - 1000
98s = 980
s = 980 / 98
s = 10
Substituting the value of 's' back into equation (1), we can solve for 't':
7s + 11t = 125
7(10) + 11t = 125
70 + 11t = 125
11t = 125 - 70
11t = 55
t = 55 / 11
t = 5
Therefore, the price of one senior citizen ticket is $10, and the price of one student ticket is $5.

A triangular prism is 12 meters long and has a triangular face with a base of 8 meters and a height of 9 meters. What is the volume of the triangular prism?
The volume of the triangular prism is 216 cubic meters.
To find the volume of a triangular prism, we need to multiply the area of the triangular base by the length of the prism.
Calculate the area of the triangular base.
The base of the triangular face is given as 8 meters, and the height is 9 meters. We can use the formula for the area of a triangle: area = (1/2) * base * height.
Plugging in the values, we get:
Area = (1/2) * 8 meters * 9 meters = 36 square meters.
Multiply the area of the base by the length of the prism.
The length of the prism is given as 12 meters.
Volume = area of base * length of prism = 36 square meters * 12 meters = 432 cubic meters.
Adjust for the shape of the prism.
Since the prism is a triangular prism, we need to divide the volume by 2.
Adjusted Volume = (1/2) * 432 cubic meters = 216 cubic meters.
Therefore, the volume of the triangular prism is 216 cubic meters.

For the acute angles in a right triangle, sin(5x)° = cos(3x + 2)°.
What is the number of degrees in the measure of the smaller
angle?
Answer is The smaller angle is 35°.
To solve for the acute angles in a right triangle when sin(5x)° = cos(3x + 2)°, we need to use trigonometric identities.
Recall that sin(x) = cos(90 - x) for any angle x. Using this identity, we can rewrite sin(5x)° as cos(90 - 5x)°.
Similarly, cos(x) = sin(90 - x) for any angle x. Using this identity, we can rewrite cos(3x + 2)° as sin(90 - (3x + 2))°, which simplifies to sin(88 - 3x)°.
Now we have cos(90 - 5x)° = sin(88 - 3x)°. Since these two expressions are equal, we can set them equal to each other and solve for x:
cos(90 - 5x)° = sin(88 - 3x)°
sin(5x)° = sin(88 - 3x)°
5x = 88 - 3x
8x = 88
x = 11
Therefore, the acute angles in the right triangle are 5x° and 90 - 5x°, or 55° and 35°. The smaller angle is 35°.

The nonsingular matrix p such that `p^-1ap` is diagonal is p = [2 -1 -1; 1 0 1; 1 1 0].
Given a matrix A `a = [ 2 -2 3; 0 3 -2; 0 -1 2]`.
Steps to diagonalize a matrix: `Set up the matrix `P` such that the eigenvectors are the columns of `P`To get the diagonalized matrix `D`, we use `P^-1 * A * P = D`.
We know that for a diagonal matrix D to exist, the matrix A must have three linearly independent eigenvectors.
The determinant of the matrix is also non zero, which means the matrix is invertible.
Let us first compute the eigenvalues of the matrix `A` by solving for det(A - λI) = 0 where `λ` is the eigenvalue of `A`.
The characteristic equation of the matrix `A` is given by: |A - λI| = 0
where `λ` is the eigenvalue of `A` and `I` is the identity matrix.
|A - λI| = |2 - λ -2 3 -2 - λ 0 -1 2 - λ|
= (λ - 1)(λ - 2)^2
=0
On solving the equation we get the eigenvalues of the matrix `A`.
Eigenvalues of `A` are `λ1 = 1, λ2 = 2, λ3 = 2`.
Let us now compute the eigenvectors of the matrix `A`.
For each eigenvalue, we have to solve the system of linear equations given by: (A - λI) X = 0
where `X` is the eigenvector.
For `λ1 = 1` we have (A - λ1I )X = 0(2 - 1 -2 3 -2 - 1 0 -1 2 - 1) X
= 0X
= [2; 1; 1]
For `λ2 = 2` we have(A - λ2I) X = 0(2 - 2 -2 3 -2 - 2 0 -1 2 - 2) X
= 0X
= [-1; 0; 1]
For `λ3 = 2` we have(A - λ3I) X = 0(2 - 2 -2 3 -2 - 2 0 -1 2 - 2) X
= 0X
= [-1; 1; 0]
The eigenvalues of the matrix `A` are `λ1 = 1, λ2 = 2, λ3 = 2`.
The eigenvectors of the matrix `A` are
`X1 = [2; 1; 1],
X2 = [-1; 0; 1],
X3 = [-1; 1; 0]`
We can now set up the matrix `P` by using the eigenvectors as columns.
That is `P = [X1 X2 X3]`.P = [2 -1 -1; 1 0 1; 1 1 0]
The inverse of the matrix `P` is given by `P^-1 = 1/6 * [1 1 1; -1 -2 1; -1 1 -1]`.
We can now compute `P^-1 * A * P` to get the diagonalized matrix `D`.
D = P^-1 * A * P = 1/6 * [1 1 1; -1 -2 1; -1 1 -1] * [2 -2 3; 0 3 -2; 0 -1 2] * [2 -1 -1; 1 0 1; 1 1 0]= diag(1,2,2).
Therefore, the nonsingular matrix p such that `p^-1ap` is diagonal is p = [2 -1 -1; 1 0 1; 1 1 0].
