Answer:
320 or 40 sorry if I´m wrong
Step-by-step explanation:
Answer:

Step-by-step explanation:
Rewrite the Pythagorean Theorem equation in terms of
.

Subtract b squared from both sides.

X^2 + y^2 - 2x + 7y + 1 = 0
(x^2 - 2x) + (y^2 + 7y) + 1 = 0
(x^2 - 2x + 1) + (y^2 + 7y) + 1 = 0+1
(x^2 - 2x + 1) + (y^2 + 7y + 49/4) + 1 = 0+1+49/4
(x - 1)^2 + (y + 7/2)^2 + 1 = 0+1+49/4
(x - 1)^2 + (y + 7/2)^2 + 1-1 = 0+1+49/4-1
(x - 1)^2 + (y + 7/2)^2 = 49/4
(x - 1)^2 + (y + 7/2)^2 = (7/2)^2
The final answer is choice B
Answer:
0
Step-by-step explanation:
According to the divergence test, for an infinite series
, the series diverges if
.
Applying the divergence test here:

Therefore, the limit of the infinite series is 0.
Answer: x = 39 because 39 + 102 = 141 and 180 - 141 = 39
