To get rid of
, you have to take the third root of both sides:
![\sqrt[3]{x^{3}} = \sqrt[3]{1}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bx%5E%7B3%7D%7D%20%3D%20%5Csqrt%5B3%5D%7B1%7D%20)
But that won't help you with understanding the problem. It is better to write
as a product of 2 polynomials:
From this we know, that
is the solution. Another solutions (complex roots) are the roots of quadratic equation.
Answer:
The Growth of sunflower duing 3 weeks is 8.5 inches or 8 (1/2).
Step-by-step explanation:
Given:
Growth of sunflower each week .
To find :
Total growth during 3 weeks?
Solution:
According to given data:
Growth is
- 1st week=2 and 1/2 inches=5/2=2.5 inches .
- 2nd week =2 and 3/4 inches=11/4 inches.
- 3rd week=3 and 1/4 inches=13/4 inches.
Total growth is given by,
=growth of (1st week +2 week+ 3 week)
=5/2+11/4+13/4
=34/4
=17/2
=8 and 1/2 inches.
Hence the overall growth is about 17/2 or 8.5 inches in 3 weeks .

Answer:
- The value of k is 12.57
- Radius of a seventeenth-century cannonball is 2.999 inches which can be rounded off to 3
Step-by-step explanation:
Let s be the surface area and r be the radius
Then according to given statement
s∝r²
Removing the proportionality symbol introduces k, the constant of proportionality
Now
A soap bubble with a 0.75 in. radius has a surface area of approximately 7.07 square inches.
Putting in the equation
The euqation beomes
Putting s = 113.1 in the equation
Hence,
- The value of k is 12.57
- Radius of a seventeenth-century cannonball is 2.999 inches which can be rounded off to 3
