Answer:
It will take 2.6 s for the ball to hit the ground.
Step-by-step explanation:
This is a standard physics problem
The equation that defines the movement of Ryans baseball is given by the initial velocity, and the acceleration
Distance = Do + Vo*t + 0.5*a*t^2
Where
Do is the initial distance.
(Do = 2m over the ground)
Vo is the initial velocity = 12m/s
a is the acceleration that is exerted on the body (in this case a = g = -9.8 m/s^2 )
t is the time
We substitute in the equation, and solve for t (time)
(0)= 2+ (12)*t + 0.5*(-9.8)*t^2
We get that
t = 2.606 s = 2.6 s
The following compounding formula applies:
A = P (1+R/2)^2t
Where, A = Amount after 5 years = $26,000; P = Amount invested now; R = Annual rate of earning = 6% = 0.06; t = time = 5 years.
Substituting;
26000 = P(1+0.06/2)^2*5 = P(1.3439)
Therefore, P = 26000/1.3439 = $19,346.44
The correct answer is d.

Answer:
9, 9√2
Step-by-step explanation:
The ratios of side lengths in a 45°-45°-90° triangle are ...
1 : 1 : √2
The other leg is the same as the first, and the hypotenuse is √2 times that.
The other sides are 9 and 9√2.
