Answer:
Step-by-step explanation:
The tough part of this question is figuring out what to do with √(7^2). You could do it by expanding the square. √(7^2) = √49
Now what is the square root of 49? Is it not 7?
√49 = 7
7^6 * 7^1
7 ^(6 + 1)
7 ^ 7
Answer:
77% of the invited guests attended the wedding.
There are a couple of different ways you could do this, but I'll show the simpler way. We will use the formula
along with the fact that the vertex has h and k coordinates of 1 and 4 respectively, and that a point on the graph is (3, 5). We could have used any point on the graph where there is a definite integer coordinate pair. We will fill in accordingly and solve for a.
and
5 = 4a + 4. If we subtract 4 from both sides we get that 
. Now we will fill in the formula and expand as needed:
and
. If we distribute the 1/4 in and then add the constants the final equation for that graph will be

Answer:
p(x) = x^4 - x^3 - 9x^2 - 11x - 4
Step-by-step explanation:
You are saying there are 3 roots of x = -1 and one x = 4 root
so...
p(x) = [(x + 1)^3 ] * (x - 4)
p(x) = (xxx + 3xx + 3x + 1 )*(x- 4)
p(x) = x^4 + 3 x^3 + 3x^2 + x - 4x^3 - 12xx - 12x - 4
p(x) = x^4 - x^3 - 9x^2 - 11x - 4
