Is it an isosceles triangle
Answer:
You cannot simplify this problem down anymore; it is at its simplest form.
Step-by-step explanation:
You cannot add together x^4 and x^2 due to the simple fact that they do not share similar exponents.
For example you could add together x^4 and x^4 to get 2x^4. But you cannot add x^4 and x^2.
So do 21/7 to give you how much they do in a day. The answer is three so they do 3 aceres in a day.
The answer would be 28 but couldnt you have done this yourself?
Answer:
The diameter will increase at a rate of 1/30π cm/min
Step-by-step explanation:
Here we want to calculate the rate at which the diameter will increase
Mathematically, the area of a sphere is given as;
A = 4πr^2
But r = d/2
so A = 4 * π * d/2 * d/2 = πd^2
dA/d(d) = 2πd
Thus dd/dA = 1/2πd = 1/2 * π * 15 = 1/30π
Given dA/dt = 10
Mathematically;
d(d)/dt = d(d)/dA * dA/dt
dd/dt = 1/30π * 10 = 10/30π = 1/3π cm/min
