Answers
Answer:
around 12.08
Step-by-step explanation:
to do this, you need to do sine cosine tangent. Make sure your calculator is in degrees, not radians. Since the only other side given is the hypotenuse, 16, and y is adjacent to the angle, you use cosine (adjacent/hypotenuse). You do cos(41) and multiply it by 16 to get 12.08
Answer:
12.1
Step-by-step explanation:
41 + x = 90
x= 49
Sine rule:
Sin90 = Sin49
16 y
y= 16sin49
y is approx. 12.1

Step-by-step explanation:
in the third step, they did 2 x -12 and got 24. It should’ve been -24 since it was a positive times a negative. It shouldve been
-24 - (-30)
-24 + 30
= 6
Answer:
yo wassup
Step-by-step explanation:
The product of two numbers with different signs is negative, so 2(-12) = -24, not 24. Then -24 — (-30) = -24 + 30 = 6.

At a local fair, the admission fees are $1.50 for children, $3 for college students, and $5 for adults.

The number of college student tickets sold was 100 less than the number of children's tickets sold.
How many children's tickets were sold?

General Formulas and Concepts:

MatricesReduced Row Echelon Form (RREF)Step-by-step explanation:
Step 1: Define Variables
x = children tickets
y = college tickets
z = adult tickets
Step 2: Define Systems
Use the given information to set up the equations.
x + y + z = 1500
1.5x + 3y + 5z = 5500
y = x - 100
Step 3: Redefine Systems
x + y + z = 1500
1.5x + 3y + 5z = 5500
-x + y = -100
Step 4: Solve for x
Rewrite [Matrix]: [tex]\left[\begin{array}{ccc}1&1&1 | 1500\\1.5&3&5 | 5500\\-1&1&0 | -100\end{array}\right][/tex][Matrix] RREF: [tex]\left[\begin{array}{ccc}1&0&0 | 400\\0&1&0 | 300\\0&0&1 | 800\end{array}\right][/tex]Here we see that our x = 400, y = 300, and z = 800. Correspond this with our defined variables and we have our answer.

A second-order differential equation with limitations on the solution y = y(x) at two different values of x makes up a second-order boundary-value issue.
What is a differential equation?
Any equation involving the abstract representation y=f(x) including one or more of its derivatives is known as a differential equation.
A function y=f(x) that fulfills the differential equation whenever f and also its derivatives are replaced into the equation is a response to a differential equation.
A system of ordinary differential equations having a solution and derivative values defined at more than one place is referred to as a boundary value problem. A two-point boundary value problem is one where the solution and derivatives are typically provided at just two positions (the boundaries).
A second-order differential equation with limitations on the solution y = y(x) at two different values of x makes up a second-order boundary-value issue. For instance, the boundary value issue y′′ + y = 0 with y(0) = 0 and y (/6) = 4 is quite straightforward.
In light of y′(0) = 0 and y′ (/6) = 4, is y′′ + y = 0.

Answers
The image of the point after a rotation of 270∘ counterclockwise about the origin is (9, 7)
How to determine what is the image of the point after a rotation of 270∘ counterclockwise about the origin?The point is given as
Point = (-7, 9)
The transformation rule is given as
270 degrees counterclockwise rotation
The rule of 270 degrees counterclockwise rotation is
(x,y) = (y,-x)
When the above rule is applied to the vertices of the point, we have:
Point' = (9, 7)
Hence, the image of the point after a rotation of 270∘ counterclockwise about the origin is (9, 7)
