The answer is 16 because 16•5=80 and then 80-9=71 yk?
Even function
(unchanged under reflection over y-axis)
Hope this helped :)
A perfect square is a number made by squaring a whole number.
Since
numbers 1, 16, 100 are perfect squares. You cannot find such whole number n, that
therefore, numbers 2, 18, 32, 44, 94 are not perfect squares.
Answer: 1, 16, 100.
It is the first equation, 3x-y=-7.
It is the only equation that both sets of points satisfy as true.
Answer:
Approximately
radians, which is approximately
.
Step-by-step explanation:
Dot product between the two vectors:
.
Magnitude of the two vectors:
.
.
Let
denote the angle between these two vectors. By the property of dot products:
.
Apply the inverse cosine function
to find the value of this angle:
.
