Answer:
The amount is $8358.7 and the interest is $3858.7.
Step-by-step explanation:
Explanation
STEP 1: To find amount we use formula:
A=P(1+rn)n⋅t
A = total amount
P = principal or amount of money deposited,
r = annual interest rate
n = number of times compounded per year
t = time in years
In this example we have
P=$4500 , r=7% , n=2 and t=9 years
After plugging the given information we have
AAAA=4500(1+0.072)2⋅9=4500⋅1.03518=4500⋅1.857489=8358.7
STEP 2: To find interest we use formula A=P+I, since A=8358.7 and P = 4500 we have:
A8358.7II=P+I=4500+I=8358.7−4500=3858.7
Answer:

Step-by-step explanation:
i think it's this i dont know i honestly forgot decimals
A.)Here, High speed Train in New York = 4.96 * 10¹ = 49.6 m/s
High speed Train in China = 0.96 * 10² = 96 m/s
As 96 > 49.6
Train in China is faster than in New York!!
B.) You need to divide, New York Train's speed from China's, as follows:
China / New York = 96 / 49.6 = 1.93
So, your final answer for this part is 1.93 times
Hope it helped!
