X + y = 2400
y = 3x
x + 3x = 2400
4x = 2400
x = 2400/4
x = 600 <== Mrs. Storey drove 600 miles
y = 3x
y = 3(600)
y = 1800 <== Mr. Storey drove 1800 miles
Answer:
The approximate volume of the sphere= 4187 cubic units
Step-by-step explanation:
<u>Points to remember</u>
Volume of sphere = (4/3)πr³
Where 'r' radius of sphere
<u>To find the volume of sphere</u>
It is given that the radius of the sphere is 10 units. ,
Here radius r = 10 units
Volume = (4/3)πr³
= (4/3) * 3.14 * 10³
= (4/3) * 3140
= 4186.666 ≈ 4187 cubic units
Answer:
Step-by-step explanation:
Given the function:
To find:
Domain of the function.
Solution:
First of all, let us learn about definition of domain of a function.
Domain of a function is the valid input values that can be provided to the function for which output is defined.
OR
Domain of a function 
are the values of 
for which the output is a valid value.
i.e. The function does not tend to 
or does not have 
form.
So, we will check for the values of for which is not defined.
For value to tend to , denominator will be 0.
So, the domain can not have x = 2
Any other value of x does not have any undefined value for the function .
Hence, the answer is:
[2 is not included in the domain].
The answer would be 5 - the square root of 24
