Answer:
Heun's method is also known by its other name called Modified Euler methods. This method is used in computational or mathematical science.
Step-by-step explanation:
Euler method is the method that is also pronounced in two similar stages such as Runge- Kutta methods. This method has been named after Dr. Heun.
This method is used for the solution of ordinary differential equations with its given values. There is some method to calculate this method. The improved Runge Kutta methods are also called the Butcher tableau method, the other methods are also called the Ralston methods.
Ignoring the "?" in your question:

If the "?" is a squared symbol that wasn't caught:

Use the quadratic formula

to get the solutions:

as you can see, the discriminant is negative, so the equation has no solution.
Well, that means that the sides and top are toutching the sphere
radius of sphere=10 so radius of cylinder=10
the height is the diameter or 20
V=hpir^2
v=20pi10^2
v=20pi100
v=2000pi
answer is D
Answer: 6.44m squared
steps:
use A = l x w
A= ?
l = 2.8m
w = 2.3m
A = (2.8m)(2.3m)
= 6.44m^2
Answer:
-4/3
Step-by-step explanation:
you do change in y over change in x which is -1-3 over -3-(-6)
when you do the calculations you get -4/3
