d = 5,000 mi the distance between the missiles
v1 = 2,000 mph the rate of the first missile
v2 = 1,000 mph the rate of the second missile
t = 1 min = 1/60 hr
Since distance = speed*time the distance 1 minute before the impact is:
v1t + v2t = t(v1 + v2) = (1/60)(2,000 + 1,000) = 50 miles.
Answer:
B. 600,000 (1.15)^{n-1}
Step-by-step explanation:
The <em>n-th</em> term of a geometric sequence with initial value a and common ratio r can be determined by multiplying the first term of the sequence (i.e. initial value a) by r^{n-1}.
The first term (i.e. initial value a) is 600,000.
The common ratio r can be calculated by dividing any two consecutive terms in the sequence:
r = 690,000/600,000 = 1.15 <em>or</em> r = 793,500/690,000 = 1.15
Thus, we get the answer:
the explicit rule that can be used to determine the value of the art collection n years after that is 600,000 (1.15)^{n-1}
Well 12 inches is a foot so 24inches is 2 feet so there is a hint so 90 divided by 12 and there is part of it
An equation because of the equal sign
