Answer: the answer is 3
Step-by-step explanation: The gradient (or slope) of the tangent to a curve at any particular point is given by the derivative at that point If y = x 3 then d y d x = 3 x 2 When x = 1 ⇒ d y d x = 3 So the slope equals 3
Answer:
they give you its a right angle. right angle means its 90 degrees. to find x simply just subtract 62 from 90
Answer:
60
Step-by-step explanation:
step one: ADD.
Answer:
And by definition the radius would be lower than the diameter and we have the following relationship:

And then the best answer would be:
B 2r
Step-by-step explanation:
When we have a circle we know that the area is given by:

And we also know that the diameter is the distance between two any points in the circle passing through the center.
And by definition the radius would be lower than the diameter and we have the following relationship:

And then the best answer would be:
B 2r
