Answer:
After 22 seconds the projectile reach its maximum height of 4,840 units
Step-by-step explanation:
we have

This is a vertical parabola downward (because the leading coefficient is negative)
The vertex is a maximum
Find out the coordinates of the vertex
Convert the quadratic equation in vertex form
Factor -10

Complete the square


Rewrite as perfect squares

The vertex is the point (22,4,840)
therefore
After 22 seconds the projectile reach its maximum height of 4,840 units

Answer:
Step-by-step explanation:
y = 4 - 3x + x^2 is to be rewritten in standard form. To do this, rearrange the terms in order of powers of x, from highest to lowest.
y = 4 - 3x + x^2 becomes y = x^2 - 3x + 4
Answer:
14
Step-by-step explanation:
I first multiplied 490 by 3/7
giving me 1470/7
I divide 1470 by 7 giving me 210
As I got 210
I multiplied 210 with 2 and got 410/3
I divided 410 by 3, getting 140.
It then said half of what was delivered was put into 5 pound bags, so
140× 1/2 or 140÷2 is 70
70 divided by 5 is 14
They made 14 5-pound bags.
