Answer:
A
Step-by-step explanation:
t to know what i8 is...
Since 8 is an even number, we can factor a 2 out of the exponent of your problem, like this:
i8=(i2)4.
But, i2=-1, so your problem becomes:
-14.
This means, multiply -1 by itself 4 times, to get 1
(Remember, -1 raised to an even power is always 1, so -14=1)
The final answer is: 1
the answer is 8, -1
the picture attached is the steps
Answer:
x=8a
Step-by-step explanation:
(3/a) x - 4 = 20
add 4 to both sides
(3/a) x = 24
Divide by 3/a
x = 24 / (3/a)
Use KCF (keep change flip)
x = (24/1) x (a/3)
x = 24a / 3
simplify
x = 8a
The answer is D, (0,-3), (0,3).
The vertices are the highest and lowest points of each parabola of the graph. O<span>n a positive parabola (one that curves upward), the vertice is the lowest point, on a negative parabola (one that curves downward), the vertice is the highest point.</span> In this particular case, the vertice of the parabola on top is (0,3) because its lowest point is (0,3). The vertice of the parabola on the bottom is (0,-3) because its highest point is (0,-3).
