which expression is equal to 6 to the fourth power:
D. 6•6•6•6
Step-by-step explanation:
6 to the fourth power is basically 6 written 4 times or 6•6•6•6.
6×6 is 36
36×6 is 216 ( we have multiplied 6×6×6 so far)
and 216×6 is 1296
A and B are not the answer bc they do not equal 1296.
C is not the answer bc 4•4•4•4•4•4 is 4096 which is not 1296
D is the only answer standing and it DOES equal 1296 so it is the answer.
Answer:
ABOVE the x-axis
Step-by-step explanation:
Please use "^" to denote exponentiation: y = x^2 + 2x + 3
To find the vertex, we must complete the square of y = x^2 + 2x + 3, so that we have an equivalent equation in the form f(x) = (x - h)^2 + k.
Starting with y = x^2 + 2x + 3,
we identify the coefficient of x (which is 2), take half of that (which gives
us 1), add 1 and then subtract 1, between "2x" and "3":
y = x^2 + 2x + 1 - 1 + 3
Now rewrite x^2 + 2x + 1 as (x + 1)^2:
y = (x + 1)^2 - 1 + 3, or y = (x + 1)^2 + 2. Comparing this to f(x) = (x - h)^2 + k, we see that h = 1 and k = 2. This tells us that the vertex of this parabola is at (h, k): (1, 2), which is ABOVE the x-axis.
Answer:
-2m
Step-by-step explanation:
-6+4 = -2 or 4-6 = -2 so -2m

Answer:
1200 ounces
Step-by-step explanation:
Let x represent the weight of 30% copper that needs to be added to the mix. Then the total weight will be (600+x) ounces, and the amount of copper in the mix is ...
0.30x +0.60(600) = 0.40(600 +x)
0.3x +360 = 240 +0.4x . . . . . simplify
120 = 0.1x . . . . . . . . . . . . . subtract 0.3x+240
1200 = x . . . . . . . . . . multiply by 10
1200 ounces of 30% copper should be added to the mix.
1. True because a straight line is a function
2. IDK because y is f(x) but it is not written there so I am guessing True.
