Answer:
a reflection over the x-axis
Step-by-step explanation:
say you plotted (1,1) and the plotted (-1,1). The result would be a reflection over the x-axis.
It'd be easier to do #18 if y ou were to break it up:
14* (first term + 14th term)
Sum from n=1 to 14 of n = S = ---------------------------------
14 2
14(1+14)
= ---------------- = 7(15) = 105
2
The sum of twice that is 210. The sum of "1 from n=1 to n=14" is just 14.
The final sum is 210 + 14 = 224 (answer)
Answer:
2
Step-by-step explanation:
We take the denominator.
That is 8.
8 goes in twice.
16÷8=2
Answer:
M/_! and M/_3
Step-by-step explanation:
Answer:
C = 8 pi cm
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
16 pi = pi r^2
Divide each side by pi
16 = r^2
Taking the square root
4 = r
The circumference is
C = 2 * pi *r
C = 2* pi *(4)
C = 8 pi cm
