Answer:
add up all the numbers then divide by the answer you got by the amount of numbers there are
Step-by-step explanation:
for example:
3,4,5,6,7
step 1
3+4+5+6+7=25
step 2
25 divided by 5 (because there are 5 numbers)=5
For this case, what you must do is place both numbers in a number line.
The largest number will be the number that is located farthest from the number 0.
We observe that the number that is furthest from zero is 5/8.
Therefore, it is fulfilled:
Answer:
See attached image to see the numeric line.
F(x)=2x^4 +5x^3 - x^2 +6x-1
Answer:
Two complex roots.
Step-by-step explanation:
F(x)=2x^4 +5x^3 - x^2 +6x-1
is a polynomial in x of degree 4.
Hence F(x) has 4 roots. There can be 0 or 2 or 4 complex roots to this polynomial since complex roots occur in conjugate pairs.
Use remainder theorem to find the roots of the polynomial.
F(0) = -1 and F(1) = 2+5-1+6-1 = 11>0
There is a change of sign in F from 0 to 1
Thus there is a real root between 0 and 1.
Similarly by trial and error let us find other real root.
F(-3) = -1 and F(-4) = 94
SInce there is a change of sign, from -4 to -3 there exists a real root between -3 and -4.
Other two roots are complex roots since no other place F changes its sign
Here,
(s-3)²=0
→s-3=0
→s=3
Substituting s=3 in,
(s+3)(s+5)
=(3+3)(3+5)
=(6)(8)
=48
B. 3/16
C. 5/16
D. 7/16
