By definition we have to:
Sin (x) = C.O / h
Where,
x = angle
C.O = opposite leg
h: hypotenuse.
Substituting values we have:
Sin (C) = AB / 82
We should look for AB. For this, we use the following relationship:
AB ^ 2 + 80 ^ 2 = 82 ^ 2
Clearing AB:
AB = root ((82 ^ 2) - (80 ^ 2))
AB = 18
Substituting we have:
Sin (C) = 18/82
Simplifying:
Sin (C) = 9/41
Answer:
the trigonometric ratio for sin C is:
Sin (C) = 9/41
Answer:
B
Step-by-step explanation:
Drop an altitude. Either of the two resulting right triangles with legs of length 5 and x and a hypotenuse of 10.
By the Pythagorean theorem, it follows that the answer is B.
Answer:
Choice 2.
Step-by-step explanation: do 3x^2+10x-8, distribute AC -(15x+4), and you would get -15x-4. Combine like terms, and get 3x^2-5x-12
It -8 because if u do -5+-6+3 it =8

<h3>
What is the general form of a quadratic equation?</h3>
The general form of the quadratic equation is given by;

Where; a, b, and c are the constants.
x; 0 1 2 3 4 5
y; 2.82 3. 29 3. 46 3. 33 2. 88 2. 24
From the table when the value of x = 0 the value of y is 2.82.
Then,

From the table when the value of x = 3 the value of y is 3.33.

From the table when the value of x = 5 the value of y is 2.24.

And the value of b is;

Therefore,
The quadratic regression equation for this data set is;

Hence, the quadratic regression equation for this data set is
.
