Answer:
y = -3x^2 +3x +6
Step-by-step explanation:
For roots p and q, the equation can be written as ...
y = a(x -p)(x -q)
The value of 'a' must be determined so that the product <em>apq</em> is equal to the y-intercept. One could say that the formula is ...
y = (y-intercept)/(pq)·(x -p)(x -q)
For your given values of p = 2, q = -1, y-intercept = 6, this becomes ...
y = 6/(2(-1))(x -2)(x +1)
y = -3(x^2 -x -2) . . . . . simplifying a bit
y = -3x^2 +3x +6
Answer:
783
Step-by-step explanation:
We have to find the sum of Arithmetic series from t = 1 to t = 18 represented by (5t - 4)
The formula to find the sum of an Arithmetic series when first and the last term is known is:
Here,
n = Total number of terms = 18
= First Term = 5(1) - 4 = 1
= 18th Term = 5(18) - 4 = 86
Using the values in the above formula, we get:
Thus, the sum of 18 terms of the given Arithmetic Series is 783.
