Answer:
B. 4
Step-by-step explanation:
Determine the constant of variation for the direct variation given.
(0, 0), (3, 12), (9, 36)
A. 3
B. 4
C.12
Direct variation is given by:
y = kx
Where,
k = constant of variation
(3, 12)
x = 3; y = 12
y = kx
12 = k*3
12 = 3k
k = 12 / 3
k = 4
(9, 36)
x = 9; y = 36
y = kx
36 = k * 9
36 = 9k
k = 36 / 9
= 4
k = 4
Constant of the variation = 4
<span>A geometric sequence is a sequence of
numbers where each term after the first is found by multiplying the
previous one by a fixed, non-zero number called the common ratio.
</span>The common ration is obtained by dividing the a term by the preceding term.
Given that f<span>our
students wrote sequences during math class with
Andre writing

Brenda
writing </span>
Camille writing
Doug writing

Notice that the common ratio for the four students is

.
For Andre, the last term is wrong and hence his sequence is not a geometric sequence.
For Brenda, the last term is wrong and hence her sequence is not a geometric sequence.
For Camille, her sequence is not a geometric sequence.
For Doug, his sequence is a geometric sequence with a common ratio of

.
Therefore, Doug wrote a geometric sequence.

Answer:
im pretty sure the answer is either a or c because. if i had to choose one though i'd probably go with C
Step-by-step explanation:
a function is a y for every x and im pretty sure both a and c display that, but a is going to all of numbers in the other bubble and there arent any other letters in the first one. hope this helps
Answer:
r = 5.58
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
97.9 = 3.14 r^2
Divide each side by 3.14
97.9/3.14 =3.14 /31.4 r^2
31.17834395 = r^2
Take the square root of each side
sqrt(31.17834395) = sqrt(r^2)
5.583757153 = r
