-->A missile is fired straight into the air from a military installation. The missile's height (in feet) is given by the formula h(x) - - 16x2 +400x + 100. ***remember to put the units***
1. How high is the missile after 4.5 seconds?
2. At what time will the missile reach its maximum height?
3. What is the maximum height the missile will reach?
4. When will the missile be 2500 feet above the ground?
5. When will the missile reach its target (on the ground)?

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
