Find the maximum volume of the cylindrical can such that the sum of its height and its circumference is 45 cm.
The maximum volume of the cylindrical can such that the sum of its height and its circumference is 45 cm is 337.5 cm³
Let's denote the radius of the cylindrical can as r, and its height as h.
The circumference of the base of the can is 2πr, so the sum of the height and the circumference can be written as:
h + 2πr = 45..(1)
We want to find the maximum volume of the can, which is given by:
V = πr²h..(2)
From (1), h = 45 - 2πr
Substitute h value in equation above
V = πr²(45-2r)
V = 45πr² - 2π²r³
To find the maximum volume, we have to find the differentiation of V
dV/dr = 90πr - 6π²r² = 0
Solving for r, we get:
r = 15/π cm
Now plug in r value in h
V = π(15/π)²(15)
= 337.5 cm³

x2+10x+=()2
step by step
The value of the expression x² + 10x, when x = 2 is 24.
In the expression x² + 10x, x represents a variable, which is a placeholder for a value that can change. We are given that x = 2, which means we substitute 2 for x in the expression:
x² + 10x = 2² + 10(2)
Here, 2² means 2 raised to the power of 2, which is 2 multiplied by itself: 2² = 2 x 2 = 4.
10(2) means 10 multiplied by 2, which is 20.
So we can substitute these values in the expression:
x² + 10x = 2² + 10(2)
= 4 + 20
= 24
Therefore, when x is equal to 2, the value of the expression x² + 10x is 24.

Given data ,
Let the probability that the student does not own a trampoline be P ( A ' )
Given that there are 14 students who own a trampoline out of 24 students in total, the probability of owning a trampoline is 14/24. Therefore, the probability of not owning a trampoline is:

p
Work out the power of the kettle if it takes 90 seconds to boil.
If your answer is a decimal, give it to 1 d.p.
The power of the kettle if it takes 90 seconds to boil given the inverse proportionality is 3 kilowatts.
What is the power of the kettle?Let
number of seconds that it takes for a kettle to boil = n
power of the kettle = p
n = 270/p
If n = 90 seconds
n = 270/p
90 = 270/p
90 × p = 270
90p = 270

Determine whether the given ordered list of numbers is a solution of the the system of equations
It should be noted that to evaluate whether an organized array of numbers serves as a resolution for a combination of equations, one can apply this method.
How to explain the methodWrite down the arrangement of equations that you wish to evaluate the solution for. For illustration, let us say that we have this system:
2x + 3y = 7
x - y = 2
Inject the data from the orderly list into the equations. For example, if the ordered list is (x=1, y=3), then we have:
2(1) + 3(3) = 7
1 - 3 = -2
Verify whether the outcome of the equations are equivalent to the values in the ordered list. If they are, then the orderly list is a resolution of the arrangement of equations. On the other hand, if not, then it is not a solution.
