Answer:
I really cant see the picture that well or, i would help.
Step-by-step explanation:
Answer:
1.)-8
2.)-5
3.)4
Step-by-step explanation:
So, the function f(x)=3x-5
The questions say "If you were to substitute these numbers what answer would you get?"
Understanding this,
First question is with x=-1
f(-1)=3(-1)-5
f(-1)=-3-5=-8
_____________________________________
f(0)=3(0)-5
f(0)=0-5=-5
_____________________________________
f(3)=3(3)-5
f(3)=9-5=4
= (16x3 - 8x2 + 4x4) / 2x
= 4x * (4x2 - 2x + x3) / 2x
= 2 * (4x2 - 2x + x3)
= 8x2 - 4x + 2x3
Answer A
Answer:
r = 45 m.
Step-by-step explanation:
pi r^2 = 6358.5
r^2 = 6358.5 / pi
r = √(6358.5 / pi)
= 44.989 m
Answer:
Step-by-step explanation:
2x² - 7x - 3 = 1
Step 1: 2x² - 7x - 4 = 0
Step 2: incorrect.
Use Quadratic Formula to solve for roots.
x = [7 ± √(7² – 4·2(-4))] / [2·2]
= [7 ± √81] / 4
= [7 ± 9] /4
= -0.5, 4
