In your lab, a substance's temperature has been observed to follow the function T()- (x- 2)3 +8. The turning point of the graph

Vlad1618 [11]

We have the function:

$T(x)=(x-2)^3+8$

A turning point happens when the function reaches a maximum or a minimum.

In that points the value of the first derivative of the function is equal to 0.

So we can find the turning points by finding the first derivative and equal to zero:

$undefined$

Find the missing leg if one leg is 18 units and the hypotenuse is 30 units

irina1246 [14]

Answer:

Step-by-step explanation:

I will assume this is a right triangle with the information given

a^2+b^2 = c^2 is the Pythagorean theorem

18^2 + b^2 = 30^2

Subtract 18^2 from each side

18^2 - 18^2+ b^2 = 30^2 -18^2

b^2 =900 -324

b^2 =576

Take the square root of each side

sqrt(b^2) = sqrt(576)

b =24
