Answer:
The value of 
is -16.
Step-by-step explanation:
We need to evaluate for x = -1, y = 5 and let us assume that z = 1
It can be simply done by putting the values of x,y and z in the given expression.
We know that the value of 4² = 16
So,
So, the value of is -16.
Answer:
The initial velocity of the runner was 4 m/s, and the runner stopped after 8 seconds.
Step-by-step explanation:
Answer:
x = 8 or x = -8
Step-by-step explanation:
x^4 - 256 = 0
<=>x^4 - 4^4 = 0
<=>(x - 8)(x + 8)(x^2 + 64) = 0
Case 1 :
x - 8 = 0
<=>x = 8 (choose)
Case 2:
x + 8 = 0
<=>x = -8 (choose)
Case 3:
x^2 + 64 = 0
<=>x^2 = -64 (nonsense)
so x = 8 or x = -8
Done :))
Answer:
an = -2 -3(n-1)
Step-by-step explanation:
an = a1+(n-1) d
a1 =-2
d = -5--2
d = -5+2
d=-3
we are decreasing by 3 each time
an = -2 + (n-1) * -3
an = -2 -3(n-1)
