Answer:
C, one angle measures more than 90 degrees.
Step-by-step explanation:
All triangles have two acute angles (less than 90 degrees)
so that eliminates A and B.
A right triangle has one 90 degree angle, so it's not D.
Obtuse is more than 90 degrees so there goes E.
Hope this helps! :)
Answer: 4 2/3
How: well you don't have to do anything to the 5 for now so make sure that 1/6 and 1/2 have common denominators...so 1/2 time 3 both top and bottom (numerator and denominator) now 1/6 - 3/6 is -2/6 and simplified is -1/3 so now you subtract 5 and 1/3 and you have to have common denominators so 5/1 times 3 with both numerator and denominator is 15/3, so 15/3 - 1/3 is 14/3 and to make in to a mixed number you have to divide,and 3 goes into 14 4 times because 4 x 3 and you can't do a number that's bigger than 14 so 12 is good ( 4 x 3) now 14 - 12 is 2 so you would have 4 2/3
+Answer:
The derivative is 2x + 2.
Step-by-step explanation:
The definition of the derivative is the limit of
[ f(x + h)^2 - f(x)] / h when h ---> 0.
For f(x) = x^2 + 2x:
Derivative = the limit as h --> 0 of f(x)
= [ (x + h)^2 + 2(x + h) - (x^2 + 2x)] / h
= [x^2 + 2hx + h^2 + 2x + 2h - x^2 - 2x] / h
= (2hx + 2h + h^2) / h
= 2x + 2 + h
The h can be neglected
So it is 2x + 2.
