Answer:
Cosecant U = 53 / 28
Step-by-step explanation:
Please see attached photo for diagram.
We'll begin by calculating the ratio of sine U. This can be obtained as follow:
Angle U = θ
Opposite = 28
Hypothenus = 53
Sine U =?
Sin θ = Opposite / Hypothenus
Sine θ = 28 / 53
Thus,
Sine U = 28 / 53
Finally, we shall determine the ratio of cosecant U. This can be obtained as follow:
Sine U = 28 / 53
Cosecant U =?
Cosecant U = 1 / Sine U
Cosecant U = 1 ÷ 28 / 53
Cosecant U = 1 × 53 / 28
Cosecant U = 53 / 28
Answer:
(-1, -1) and (2, 2)
Step-by-step explanation:
Substitute for y in the first equation and solve the quadratic.
x = x^2 -2
x^2 -x -2 = 0 . . . . subtract x
(x -2)(x +1) = 0 . . . .factor
Solutions are the values of x that make these factors be zero:
x = 2, x = -1
Since y=x, the solutions are ...
(x, y) = (-1, -1) and (2, 2)
Answer:
you have to add them together
Wow ! If I understand what's go0ing on here, then
we have to be careful, and THINK .
I was going to ask you "What does Ф mean ?", and then I realized,
Ф is a new operation that the teacher invented.
The first line on the board is the definition of Ф .
Ф means "<u>Add the two numbers and subtract 4</u>."
Now you have to use this new invention to find the value
of the second line:
Take care of the stuff inside the parentheses first: ( 4 Ф 2 )
<u>Add the two numbers and subtract 4
</u>4 + 2 - 4 = <u>2</u><u>
</u>That's the part inside the parentheses. It's <span><u>2</u> .</span><u>
</u>NOW, we have to do the new operation with the 2 inside,
and the 3 that's outside the parentheses:<u>
</u>3 Ф 2
<u>Add the two numbers and subtract 4</u>
3 + 2 - 4 =<u> 1</u>
And that's the final value of 3 Ф (4 Ф 2) . It's <u>1</u> .
Pretty sneaky.

Answer:
2/3
Step-by-step explanation:
Even numbers are 2,4,6,8,10,12,14
Multiple of 3 ( other than 6,12 ) are 3,9,15
P=10/15 (simplify by 5)
P=2/3
