Answer:
Step-by-step explanation:
We want to find a quadratic that passes through the points:
In intercept form.
First, note that the first two given points are the <em>x</em>-intercepts of our quadratic. Intercept or factored form is given by:
Where <em>p</em> and <em>q</em> are the <em>x</em>-intercepts, and <em>a</em> is the leading coefficient.
So, we will substitute -4 and 2 for <em>p</em> and <em>q: </em>
Simplify:
Next, the third point (6, -20) tells us that <em>y</em> = -20 when <em>x</em> = 6. So:
Solve for <em>a: </em>
Thus:
Hence, our equation in intercept from is:
Answer:B

Answer:
Solution:
<u>Let's use PRT/100 to find the simple interest.</u>
- 3500 x 7.5 x 3/100 = Interest
- → 35 x 7.5 x 3 = Interest
- → 35 x 7.5 x 3 = Interest
- → $787.5 = Interest
Hence, the simple interest is $787.5.
