Answer:
The object will reach its highest point 0.5 seconds after it has been thrown.
Step-by-step explanation:
The object reaches its maximum height when velocity is equal to zero, the velocity is the derivative of function height. That is:
(1)
Where 
is the velocity of the object at time 
, in feet per seconds.
If we know that 
and 
, then the time when object reaches its highest point is:
The object will reach its highest point 0.5 seconds after it has been thrown.

Answer:
$2353 at 12.5% and $7647 at 8.25%
Step-by-step explanation:
I'll say a is the amount he invested in one market, and b is the amount in the other.
a + b = 10000, or b = 10000 - a
multiplying the investments with the percentages and adding them together will give the total earned interest.
(a × 0.125) + (b × 0.0825) = 925
0.125a + 0.0825b = 925
Use substitution to solve for a.
0.125a + 0.0825(10000 - a) = 925
0.125 a + 825 - 0.0825a = 925
0.0425a = 100
a = 2352.94
Use substitution to find b
b = 10000 - 2352.94
b = 7647.06
The questions are to the nearest dollar so round a and b.
$2353 and $7647
Answer:
A. 9.8 ft
Step-by-step explanation:
first convert the degrees to radians:
80° x (pi/180) ≈ 1.396
arc length = r x θ (always in radians)
= 7 x 1.396
= 9.772 ≈ 9.8 ft
