Answer:
<h3>1 secs</h3>
Step-by-step explanation:
Given the height of the discus can be modeled by the equation y=−16x
^2
+32x+4, where y represents the height in feet of the discus in seconds, the velocity of the discus at its maximum height is zero.
Velocity v = dy/dx = 0
dy/dx = -32x + 32
0 = -32x + 32
32x = 32
x = 1 secs
Hence it will take the discus 1 secs to reach its maximum height
Use the formula i=prt, where i is the interest earned, p is the principal, r is the rate (as a decimal fraction) and t is the elapsed time, in years.
Here i = $72 = $1200 r (9/12) (9 months is 9/12, or 3/4, of 1 year)
Reducing,
$72 = $900r
Solving for r, r=0.08, or 8 percent per year.
So this is so easy
the answer is33
pay attention what i’m saying:
if you have a circle like this and you have arc if the arc doesnt pass the center of the circle and fit to the environment of circle the measure of angle is half of the measure of arc
2500 is 40% of the 100%
so, from the 40%, figure out 10%
2500/4=600
600 x 6=3,600
so, 3,600 is the answer
