D. 16.8 units
A radius is half of the diameter, so to get the answer all you need to do is multiply the length of the given radius by 2.
8.4x2= 16.8
To arrange in ascending order means to arrange numbers from the smallest value to the greatest value in the set of numbers provided.
9) 3.021 < 3.12 < 3.121 < 3.21
Look at the 1st decimal place after the point first. 0 is less than 2 & 1, so 3.021 is the least number. Now, for 3.12 & 3.121, look at the 3rd place. 3.12 = 3.120, so it’s smaller than 3.121. Then comes 3.21 which is the greatest number in this set.
10) 5.0090 < 5.05 < 5.059 < 5.5
Here, 5.0090 is the smallest number. Then comes 5.05 = 5.050 which is smaller than 5.059. 5.5 is the greatest number.

Answer:it will take 5 years
Step-by-step explanation:
Initial amount deposited into the account is $500 This means that the principal is
P = 500
It was compounded quarterly. This means that it was compounded 4 times in a year. So
n = 1
The rate at which the principal was compounded is 5.6%. So
r = 5.6/100 = 0.056
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years. A is already given as $750
Therefore,
750 = 500 (1+0.056/4)^4×t
750 = 500 (1+0.014)^4t
750 = 500 (1.014)^4t
(1.014)^4t = 750/500 = 1.5
Take root 1/4 of both sides
(1.014)^4t ×1/4 = 1.5^1/4
(1.014)^t = 1.107
t = 5 years
Answer:
x^6
Step-by-step explanation:
(x^2)^3 the power inside would multiply the power outside the parentheses so it gives us
x^2*3=x^6
