What is a square plus b square?
C Square
Project on the whole square of a plus b plus c?
(a+b+c)²=a²+b²+c²+ 2ab+2bc+2ac
If A is proportional to B square and B is proportional to C Square then A is proportional to?
A is proportional to C4.
Show that among all rectangles with area A the square has the minimum perimeter?
Suppose sqrt(A) = B ie the square with sides B has an area of A and its perimeter is 4*B. Now consider a rectangle with sides C and D whose area is A. So C*D = A = B*B so that D = B*B/C Perimeter of the rectangle = 2*(C+D) = 2*C + 2*D = 2*C +2*B*B/C Now consider (C-B)2 which, because it is a square, is always >= 0 ie C*C + B*B - 2*B*C >= 0 ie C*C + B*B >= 2*B*C Multiply both sides by 2/C (which is >0 so the inequality remains the same) 2*C + 2*B*B/C >= 4*B But, as shown above, the left hand side is perimeter of the rectangle, while the right hand side is the perimeter of the square.
How do you calculate the diagonal in a rectangle?
You do a^2 x b^2 = c^2 where a=the base, b= the height and c=the diagonal.More info: take the square of "a" and the square of "b" and multiply them together, then take your answer and find the square root of it, that is "c" (the diagonal).
How do you complete a square in a math problem?
Here are the steps: ax^2 + bx + c = 0 Subtract c and divide by a x^2 + (b/a)x = -(c/a) Take the square of (b/a)/2 and add it to both sides (x + ((b/a)/2))^2 = -(c/a) + ((b/a)/2)^2 Take the square root of both sides Subtract ((b/a)/2) and you have your solutions: x = -(c/a) + ((b/a)/2)^2 - ((b/a)/2) x = (c/a) - ((b/a)/2)^2 - ((b/a)/2)
Solve for a c equals the square root of a squared plus b square?
This question cannot be answered. You will have to give me the number to the square root. * * * * * a = ±sqrt(c^2 - b^2)
How is the square root of a number found?
Let x be the parameter to be taken square root. a = 0 b = x loop: c = (a+b)/2 if c*c > x then b = c else a = c Repeat until accurate enough result is obtained in c or until c*c equals x.
What is the square root of a squared plus b squared?
It's the square root of a2+b2. It cannot be simplified. It is NOT a+b. The answer is c square.
A plus b-c whole square?
(a+b-c)2 = a2 + b2 +c2 +2ab - 2bc - 2ac
When a squared plus b squared equals c squared what is the square root of the square root of the square root of a squared squared squared plus b squared squared squared?
Since a squared plus b squared equals c squared, that is the same as c equals the square root of a squared plus b squared. This can be taken into squaring and square roots to infinity and still equal c, as long as there is the same number of squaring and square roots in the problem. Since this question asks for a and b squared three times, and also three square roots of a and b both, they equal c. Basically, they cancel each other out.
Find the area of a trapezoid?
Area measured in square units = 1/2*(sum of parallel sides)*height If a and b are parallel, and b>a ((a+b) sqrt((a-b+c-d) (a-b-c+d) (a-b+c+d) (-a+b+c+d)))/(4 (b-a))
