Answer:
C
Step-by-step explanation:
To determine which point lies on the graph, substitute the x-coordinate into f(x) and if the value is equal to the y-coordinate then the point is on the graph
A (15, 1)
f(15) = 3 ×
≠ 1 ← not on graph
B (0, 15)
f(0) = 3 ×
= 3 × 1 = 3 ≠ 15 ← not on graph
C (1, 15)
f(1) = 3 ×
= 3 × 5 = 15 ← lies on graph
D (0, 0)
f(0) = 3 ×
= 3 × 1 = 3 ≠ 0 ← not on graph
Answer:
n^2 + 2n.
Step-by-step explanation:
n = 1 2 3 4 5
term t = 3 8 15 24 35
Diffs = 5 7 9 11
2 2 2 - so the nth term contains n^2.
n^2 = 1 4 9 16 25
t - n^2 = 2 4 6 8 10
This is an arithmetic sequence with nth term = 2 + (n-1)2 = 2n
So the nth term of the quadratic sequence = n^2 + 2n.
Answer:
Step-by-step explanation:
cos theta is 2/3 because cos means reciprocal of sec
C
Angle 1 and 2 make up a straight angles and straight angles always equal 180.
Subtract 35 from 180 to find Angle 2s measure which is 145
Answer:
The question gives the fact that both lines are parallel.
So:
3p - 15 = 7p - 5
3p = 7p + 10
-4p = 10
p = 10/-4
p = 5/-2
