-->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?
2600 feet
4. When will the missile be 2500 feet above the ground?
5. When will the missile reach its target (on the ground)?

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.

step-by-step explanation:

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .
