Answer:
The conjecture cannot work for any negative numbers, It works for x > 1.3.
Step-by-step explanation:
An odd power preserves the sign. For |x| > 1, the power increases the magnitude. For x < 0, adding -2 only increases the magnitude more. A negative number of larger magnitude will not be "greater than" the reference. It will be "less than."
It only takes a counterexample to show the conjecture is incorrect.
x^5 -2 ?? x
(-2)^5 -2 ?? (-2)
-32 -2 ?? -2
-34 < -2 . . . . . . not greater than
Answer:
$0.97
Step-by-step explanation:
7328*100/108^(4*29)
a bunch of math later, with rounding...
0.97
*note-may be wrong
Answer:
y=-9/2x plus 4
Step-by-step explanation:
y=ax plus b
Use points from the task.
4=0x plus b
so b=4
-5=-2a plus 4
-2a = -9
a = -9/2
y=-9/2x plus 4
For three lengths two be able to be the sides of a triangle, the longest side must be less than the sum of the two other sides.
A.
25 is the longest side.
16+10=26
25<26
It is possible.
B.
15 is the longest side.
13+12=25
15<25
It is possible.
C.
18 is the longest side.
5+10=15
18 is NOT less than 15.
It is not possible.
D.
15 is the longest side.
8+8=16
15<16
It is possible.
Therefore, the answer is c.
Hope this helps!
15 i think sorry if its wrong
