Answer:
Step-by-step explanation:
-16
Answer: -16
Step-by-step explanation:
-4 x -4 = -16
squaring is basically just multiplying the # by itself.
a = 4i + 3j, b = -4i + 4j
The required dotproduct of the given vector is given as -4.
Given that,
a = 4i + 3j, b = -4i + 4j
a • b is to be determined.
The dot × of twovectors is described as the sum of the products of the relevant directionalvector.
Here,
a.b = (4i + 3j).(-4i + 4j)
a.b = 4×-4 (i.i) + 3×4 (j.j) + 4×4 (i.j) + 3×-4(i.j)
a.b = -16 + 12
a.b = -4 (since i.j or j.i for dot product gives zero.)
Thus, the required dotproduct of the given vector is given as -4.

g(x) = 4(x2 – 6x + 9) + 1
g(x) = –3(x2 – 8x + 16) – 6
g(x) = 8(x2 – 6x + 9) – 5
Answer:
g(x) = 8(x2 – 6x + 9) – 5
Step-by-step explanation:
A function with a form (x - a)^2 - b where a and b are some constants are a transformation to the right and down from the parent function, f(x) = x^2. Then, option:
g(x) = 4(x2 – 6x + 9) + 1 = 4(x - 3)^2 + 1
is discarded
The vertex form of a quadratic equation is f(x) = c*(x - h)^2 + k, where c, h and k are all constant, and point (h,k) is the vertex of the quadratic function. If c > 0, then the vertex is a minimum and if c < 0 then the vertex is a maximum. Therefore, options:
g(x) = –9(x2 + 2x + 1) – 7 = -9(x + 1)^2 - 7
g(x) = –3(x2 – 8x + 16) – 6 = -3(x - 4)^2 - 6
are dicarded
In consequence, the correct option is:
g(x) = 8(x2 – 6x + 9) – 5 = 8(x - 3)^2 - 5
Answer:
The last choice is the one you want
Step-by-step explanation:
First of all, a parabola has a minimum value if it is a positive parabola, one that opens upward. The first and the third parabolas are negative so they open upside down. That leaves us with choices 2 and 4. We find the side to side and up or down movement by finishing the completion of the square that has already been started for us. Do this by factoring what's inside the parenthesis into a perfect square binomial.
The second one factored becomes:
which reflects a shift to the right 3 and up 1. Not what we are asked to find.
The fourth one factored becomes:
which reflects a shift to the right 3 and down 5. That's what we want!
