You apply the rule to put the exponent in front, and lower it by one. But since this is a nested expression, you apply it twice:
4*(5x^3-4)^3 * 3*5x^2 =
60x^2 (5x^3-4)^3
Answer:
The value of radius is 34.395..
Step-by-step explanation:
The formula for finding the circumference of the circle is:
C=2πr.
Here we have given the values:
circumference = 216 units
π = 3.14.
r = ?
Substitute the values in the formula:
216 = 2(3.14)r
216=6.28r
Now divide both sides by 6.28.
We get,
216/6.28 = 6.28r/6.28
34.395=r
Thus the value of radius is 34.395...
Answer:
5000 ;
11125
Step-by-step explanation:
Given :
Total principal = 16125
Rates = 8.5% and 4%
Period, t = 2 years
Total interest = 1740
Let :
Principal amount invested at 8.5% = x
Principal amount invested at 4% = 16125 - x
Interest formula :
Interest = principal * rate * time
Hence, mathematically ;
(x * 8.5% * 2) + [(16125 - x) * 4% * 2] = 1740
(0.17x + 1290 - 0.08x ) = 1740
0.09x + 1290 = 1740
0.09x = 1740 - 1290
0.09x = 450
x = 450 / 0.09
x = 5000
Amount invested at 4% :
16125 - 5000 = 11125

Answer: 25y/2x
Explanation:
First you need to find the GCF of 125 and 10, which is 5
making it 25y^2/2xy, Then you get rid of 1 of the y's from both of the sides because you don't need them, they cancel eachother out, 25y/2x
I hope this helped!
