Answer:
<u>The lengths of side A is 22.4 and B is 11.9</u>.
Step-by-step explanation:
Given:
If side A is twice as long as B and C is 25 using the Pythagorean Theorem.
Now, to find the lengths of side A and B.
Let the side B be 
So, the side A be 
Side C = 25.
Now, to solve by using Pythagorean Theorem:
A² + B² = C²
<em>Dividing both sides by 5 we get:</em>
<em>Using square root on both sides we get:</em>
<u>B rounding to the nearest tenth = 11.9.</u>
Now, to get A by substituting the value of 
:
<u>A rounding to the nearest tenth = 22.4.</u>
Therefore, the lengths of side A is 22.4 and B is 11.9.
According to the vertex and the directrix of the given parabola, the equation is:
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:
In which a is the leading coefficient.
The directrix is at y = k + 4a.
In this problem, the vertex is (1,4), hence:
The directrix is at y = 7, hence:
Hence, the equation is:

Answer:
5/4 is your slope.
Step-by-step explanation:
5-0= 5
4-0= 4
slope is chang in y over change in x. Your first point is (0,0) and you second is (4,5).
