Answer:
Here we will use the relationships:
And a number:
is between 0 and 1 if a is positive and larger than 1, and n is negative.
if a is positive and 0 < a < 1, then we need to have n positive such that:
0 < a^n < 1
A) 
This is between zero and 1,
B) 
This is greater than 1, because the exponent is positive.
C) 
Because a is smaller than 1, and the exponent is positive, then the expression is between 0 and 1.
D) 
The exponent is negative (and pair) then the expression is between 0 and 1.
Remember that when the exponent is pair, we always have that:
(-N)^m = (N)^m
So (-7)^-2 = 7^-2
Answer:
-85
Step-by-step explanation:
(-8.5)(-5)(-2)
=(-8.5)(10)
=-85
Answer:
-3 is a zero of the function False
-1 is a zero of the function True
1 is a zero of the function False
2 is a zero of the function True
4 is a zero of the function False
Hey!
----------------------------------------------------------------------
We know that (a = -3), (b = 2), (c = 5), and (d = -4).
----------------------------------------------------------------------
Solution #1:
≈ 1.57
----------------------------------------------------------------------
Solution #2:
= a - 4b / 3c + 2d
= (-3) - 4(2) / 3(5) + 2(-4)
= (-3) - 8 / 15 + (-8)
= (-3) - 0.53 + (-8)
= (-3.53) + (-8)
= -11.53
----------------------------------------------------------------------
Solution #1 Answer: 1.57
Solution #2 Answer: -11.53
