The answer is 8%
Compound interest formula is:
A = P(1 + r/n)ⁿˣ
A - the final amount
P - the initial amount
r - interest rate
n - number of compoundings per year
x - time period
We have:
A = <span>$1389.08
P = </span><span>$1000
r = ?
n = 2 (it is semiannual)
x = 4
</span>A = P(1 + r/n)ⁿˣ
1389.08 = 1000(1 + r/2)²*⁴
1389.08 = 1000(1 + r/2)⁸
(1 + r/2)⁸ = 1389.08/1000
(1 + r/2)⁸ = 1.389
r = 0.08 = 8/100 = 8%
SOLUTION
The quotient of a number and -15, simply means the number divided by -15.
So, let the unknown number be x,
This statement can be written mathematically as
This becomes
Hence, the number is equivalent to -1,500
Given , h = -16 + 50t where h is the height of the rocket in feet and t is the time in seconds after liftoff.
The rocket will remain in the air till it reaches the ground.
To find the time taken to reach the maximum height we use a formula
t =
From the given equation , a= -16 , b= 50
Apply the values in the formula
t =
t = 1.5625 seconds
The rocket will reach the maximum point in 1.5625 seconds and it reaches the ground in another 1.5625 seconds.
1.5625 + 1.5625 = 3.125 seconds
The rocket will remain in the air for 3.1 seconds
Answer:
C. 500
Step-by-step explanation:
Given that
The ordering cost per order is $50
The carrying cost percentage is 20%
The weekly demand is 100 units and there are 50 weeks in the work year
The cost per unit is $10
We need to find out the economic order quantity i.e. EOQ
So we applied the above formula
= √(2 × weekly demand × no of weeks × ordering cost) ÷ √(carrying cost × cost per unit)
= √(2 × 100 × 50 × $50) ÷ √(20% × $10)
= √(500,000 ÷ 2)
= 500 units
hence, the option c is correct
