cscθ is the same as 1/sinθ
Explanation:
csc stands for cosec which is equivalent to 1/sinθ
The expression is thus equal to 1/[sin(4π/3)]
Since we know by consulting the unit circle that sin(4π/3) = - [(√3)/2]
we get the expression 1/[sin(4π/3)] = 1/(-√3/2)
which can be simplified to 1/(-√3/2) = 2/(-√3) = (-2√3)/3
Identify the probability of rolling a prime number and then rolling a multiple of 2 when a number cube is rolled twice.
The Probability of rolling a prime number and then rolling a multiple of 2 is 1/4 or 0.25.
A number cube is rolled, there are six possible outcomes: 1, 2, 3, 4, 5, and 6. To determine the probability of rolling a prime number and then rolling a multiple of 2, we need to first identify the prime numbers and the multiples of 2.
The prime numbers are 2, 3, and 5. There are three prime numbers out of a total of six possible outcomes, so the probability of rolling a prime number on the first roll is 3/6 or 1/2.
The multiples of 2 are 2, 4, and 6. There are three multiples of 2 out of a total of six possible outcomes, so the probability of rolling a multiple of 2 on the second roll is also 3/6 or 1/2.
To find the probability of both events occurring, we can multiply the probabilities of each event. Therefore, the probability of rolling a prime number and then rolling a multiple of 2 when a number cube is rolled twice is:
(1/2) × (1/2) = 1/4
So the probability of rolling a prime number and then rolling a multiple of 2 is 1/4 or 0.25.

Suppose w = x+y where x = e^t, y=2+sin(2t), and z = 2 + cos(5t).A) Use the chain rule to find dw/dt as a function of x, y, z, and t. Do not rewrite x, y, and z in terms of t, and do not rewrite e as x. dw/dt =____?
To find dw/dt using the chain rule, we need to differentiate w = x + y with respect to t. We are given that x = e^t, y = 2 + sin(2t), and z = 2 + cos(5t).
Using the chain rule, the derivative of w with respect to t, dw/dt, can be found as follows:
dw/dt = dx/dt + dy/dt
Now, let's find the derivatives of x and y with respect to t:
dx/dt = d/dt(e^t) = e^t
dy/dt = d/dt(2 + sin(2t)) = 2cos(2t)
Substituting these derivatives into the expression for dw/dt, we have:
dw/dt = dx/dt + dy/dt
= e^t + 2cos(2t)
Therefore, dw/dt = e^t + 2cos(2t).

The equation of the function in standard form is -5.83x² + 816.2x - 25895 (option c).
To find the equation of the function in standard form, we can use the given values of f(x) and x to form a system of equations. Since we know that the function is quadratic, we need at least three values of f(x) to solve for the constants a, b, and c.
Using the given values from the table, we can form the following system of equations:
1,272 = a(50)² + b(50) + c
1,884.5 = a(55)² + b(55) + c
2,322 = a(60)² + b(60) + c
2,584.5 = a(65)² + b(65) + c
2,672 = a(70)² + b(70) + c
2,584.5 = a(75)² + b(75) + c
2,322 = a(80)² + b(80) + c
To find the vertex of the parabola, we can use the formula h = -b/2a and k = f(h). Once we have the vertex, we can substitute its values into the vertex form of the equation to get the standard form of the quadratic function.
Using the given values from the table, we can find the vertex of the parabola:
h = -b/2a b = (f(60) - f(70))/(60-70)
b = -49 h = -b/2a 60 = -(-49)/(2a)
a = -5.83
k = f(h) k = f(60) k =25,895
Now, we have the values of a, h, and k, which we can substitute into the vertex form of the equation:
y = a(x-h)² + k y = -5.83x² + 816.2x - 25895
Expanding this equation, we get:
y = -5.83x² + 816.2x - 25895
This is the equation of the function in standard form.
Therefore, the answer is (C) -5.83x² + 816.2x - 25895

Explanation:
Imagine a pizza split into 5 equal slices. Then imagine that you split each slice in half. This means we now have 5*2 = 10 slices.
Eating 3 out of the original 5 is equivalent to eating 6 smaller slices out of the now 10 total.
In other words: The fraction 3/5 is the same as 6/10
Put another way: Multiply top and bottom of 3/5 by 2 to get 6/10.

Gary painted 3/10 of the fence in the morning, and then 3/5 of it in the afternoon. We can replace the "3/5" with "6/10".
3/10 in the morning6/10 in the afternoon3/10 + 6/10 = (3+6)/10 = 9/10 total
Going back to the pizza scenario, we can imagine 3/10 as eating 3 slices out of 10 total. Then 6/10 adds 6 more slices to get 3+6 = 9 slices total. That's how we end up with 9/10 as the answer.
Calculate the median of the following data 18, 24, 55, 59, 34, 39, 22, 32, 57, If 55 is replaced by 33, calculate the new median
Answer:
34, and if 55 was replaced with 33, the new median would be 33.
Step-by-step explanation:
The median is the number that is in the middle of a data set, once the numbers are organized from least to greatest. If we put the numbers in order (18, 22, 24, 32, 34, 39, 55, 57, 59), the number in the middle is 34. If we do the same, but replace 55 with 33, (18, 22, 24, 32, 33, 34, 39, 57, 59), we get 33 as the median.

Using an integrating factor, solve y-y-5 CD- in the method for solving a first-order linear differential equation, the first step is to put the equation in the standard form y alty bit). is the given equation in the standard form? No Yes Identify a(t) and bit)
The value of a(t) is -1 and b(t) is 55 + \(e^t\)
No, the given equation y' - y = 55 + \(e^t\) is not in the standard form of a first-order linear differential equation.
In the method for solving a first-order linear differential equation, an integrating factor is a function used to transform the equation into a form that can be easily solved.
For an equation in the standard form y' + a(t)y = b(t), the integrating factor is defined as:
μ(t) = e^∫a(t)dt
To solve the equation, you multiply both sides of the equation by the integrating factor μ(t) and then simplify. This multiplication helps to make the left side of the equation integrable and simplifies the process of finding the solution.
To put it in standard form, we need to rewrite it as y' + a(t)y = b(t).
Comparing the given equation with the standard form, we can identify:
a(t) = -1
b(t) = 55 + \(e^t\)
Therefore, The value of a(t) is -1 and b(t) is 55 + \(e^t\)

Can someone show me how to factor this please?
Answer:
\(\displaystyle \theta = \left\{\frac{7\pi}{6}, \, \frac{3\pi}{2}, \frac{11\pi}{6}\right\}\)
Step-by-step explanation:
We want to solve the equation:
\(2\sin ^2 \theta + 3\sin \theta + 1 = 0\)
In the interval [0, 2π).
Notice that this is in quadratic form. Namely, by letting u = sin(θ), we acquire:
\(\displaystyle 2u^2 + 3u + 1 = 0\)
Factor:
\(\displaystyle (2u+1)(u+1) = 0\)
By the Zero Product Property:
\(\displaystyle 2u + 1 = 0\text{ or } u + 1 = 0\)
Solve for each case:
\(\displaystyle u = -\frac{1}{2} \text{ or } u = -1\)
Back-substitute:
\(\displaystyle \sin \theta = -\frac{1}{2} \text{ or } \sin \theta =-1\)
Use the Unit Circle. Hence, our three solutions in the interval [0, 2π) are:
\(\displaystyle \theta = \left\{\frac{7\pi}{6}, \, \frac{3\pi}{2}, \frac{11\pi}{6}\right\}\)
