Answer:
t = 4
Step-by-step explanation:
Anything divided by itself is 1
Option B:
A ray has two endpoints and extends infinitely in both directions.
Solution:
Option A: Two lines that intersect are called skew lines.
It is false because,
Two lines are said to be skew lines if they do not intersect and do not lie in the same plane.
Option B: A ray has two endpoints and extends infinitely in both directions.
It is false because,
A ray has one endpoint and extends infinitely in one direction.
Option C: A line is a set of points that extends infinitely in both directions.
It is false true.
A line is a set of points that extends infinitely in both directions.
Option D: Two lines in the same plane are said to be perpendicular if they never intersect.
It is false because,
Two lines are said to be perpendicular if they are intersect.
Hence Option B is true. A line is a set of points that extends infinitely in both directions.
I think it would be any number closest to 30,000 so maybe 29,900. Hope it's correct.
Answer:
$496, 000
Step-by-step explanation:
2021 is 11 years since 2010, hence t = 11
Substitute t = 11 into the equation
p = (1.95 × 11²) + (12.25 × 11) + 125
= 235.95 + 134.75 + 125
= 495.7 ( thousands of dollars ), thus the best estimate is
p = $ 496, 000
Answer:
237.9 meters
Step-by-step explanation:
Let x represent the length of the tunnel.
Applying the Cosine Law, we have:
x² = 201² + 146² - 2*201*146*Cos(85)
x² = 61,717 - 58,692*0.0872
x² = 61,717 - 5,117.9424
x² = 56,599.0576
x = √56,599.0576
x = 237.9 m (nearest tenth)
