Answer:
Lim (f(9+h)-f(9))/h as h->0 = 2916
Step-by-step explanation:
f(x)=x⁴
f'(x)
= Lim (f(9+h)-f(9))/h as h->0
= 4x³
At x = 9, f'(x) = f'(9) = 4*9³ =4*729 = 2916
(btw if i write 4x^3 it means 4x to the power of 3)
1) (2x+3)(x-2)
2x^2 -4x + 3x -6
2x^2 -x -6
2) x^2 +10x +24
(x+12)(x-2)
3) 6x^2 -13x +6
(2x )(3x ) not sure on this one
4) x^2 +8x +15
(x+3)(x+5)
x= -3 x=-5
5) x^2 -4x -45
(x+5) (x-9)
x=-5 x=9
hope this helps, if you need any help understanding what happens just ask
Answer:
10
Step-by-step explanation:
By Pythagoras' Theorem:
16 + r = √(24^2 + r^2)
(16 + r)^2 = 24^2 + r^2
256 + 32r + r^2 = 576 + r^2
32r = 320
r = 10
