Well the equation is (A^2)+(B^2)=(C^2)

A= x
B= 2x
C will always be the longest side because it is the Hypotenuse = 25

So if you plug in those numbers into the equation...

(x^2) + (2x^2) = (25^2)

x^2 + 4x^2 = 625

Combine like terms

5x^2 = 625

Divide by five to both sides

x^2 = 125

Then Square root,

x = sqrt(125)

x = sqrt(25* 5)

x = 5sqrt(5)

Alla [95]

Answer:

If its a cube function. Then I think this is the answer. Can you mark brainliest? And can you tell me if it's right or wrong?

Step-by-step explanation:

Consider the cubic function f(x) = ax^3 + bx^2 + cx + d. Determine the values of the constants a, b, c and d so that f(x) has a point of inflection at the origin and a local maximum at the point (2,...

Consider the cubic function f(x) = ax^3 + bx^2 + cx + d. Determine the values of the constants a, b, c and d

so that f(x) has a point of inflection at the origin and a local maximum at the point (2, 4). ==>c=3
