Answer:
y = x² + 2x + 5
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here the vertex = (- 1, 4), thus
y = a(x + 1)² + 4
To find a substitute (0, 5) a point on the graph into the equation
5 = a(0 + 1)² + 4
5 = a + 4 ( subtract 4 from both sides )
a = 1, thus
y = (x + 1)² + 4 ← expand and simplify
= x² + 2x + 1 + 4
= x² + 2x + 5
Answer:
3.68
Step-by-step explanation:
If 3/5 of the weight is apples, then 2/5 of the weight is pears.
2/5 * 9.2 = 3.68

If a company makes two discounts with one being made first and then another, the equivalent discount is 37%.
<h3>What was the equivalent discount?</h3>
Assume that the price of a good in the company was $10.
The initial discount of 30% takes the price to:
= 10 x ( 1 - 30%)
= $7
Then there is a 10% discount:
= 7 x (1 - 10%)
= $6.30
The equivalent discount is:
= (10 - 6.3) / 10
= 37%
