Answer:
sin ∠A = 3/5
Step-by-step explanation:
sin ∠A = opposite side/hypotenuse
sin ∠A = 3/5
Hope it helps, Cheers!
EXPLANATION:
STEPS:
1.First we have to find the partial distances in the two equations given and then find the total, but to do so we must find the value of x, then replace it in each of the equations and finally the sum will give us the total of all the magnitudes.
2.
Answer: Yes it is
Step-by-step explanation:

Re-write with common denominator, in this case 6:

Answer:


Step-by-step explanation:
<u>Factored form of a quadratic function</u>

where:
- p and q are the x-intercepts
- a is some constant
Given x-intercepts:
Therefore:


To find a, substitute the given vertex (2, -8) into the equation and solve for a:



Therefore, the function's equation in factored form is:

<u>Vertex form of a quadratic equation</u>
<u />
where:
- (h, k) is the vertex
- a is some constant
Given:
Therefore:

To find the constant a, substitute one of the x-intercepts into the equation and solve for a:



Therefore, the function's equation in vertex form is:
