Answer:
x = 2 degree and unknown angle = 31 degree
Step-by-step explanation:
149 + 13x + 5 =180 degree (being linear pair)
154 + 13x = 180
13x = 180 - 154
x = 26/13
x = 2 degree
unknown angle = 13x + 5
=13*2 + 5
=26 + 5
=31 degree
Answer:
1 meter farther
Step-by-step explanation:
The difference in time from 4 seconds to 10 seconds is 6 seconds.
The speed is half of the difference of time.
That is why the speed is 3 m/s.
The difference in time from 10 to 18 is 8 seconds.
Take the time and divide it by 2 to get the speed.
The speed is 4 m/s.
The object's position is 1 more meter.
4 m/s - 3 m/s = 1 m/s
Answer:
ARC= 15.7
ARC= 2(3.14)10(90/36)
Step-by-step explanation:
Step-by-step answer:
standard deviation (sigma) = 12 inches
mean (mu) = 90 inches.
For 36 years, the standard error of the mean is
e = sigma / sqrt(n) = 12" / sqrt(36) = 2".
Deviation from the mean
= 92.8 -90 = 2.8
Since the standard error of the mean follows the normal distribution, we have
Z=(92.8-90)/2 = 1.4
Looking up the normal distribution tables, or check R, we find
P(Z>1.4) = 1-P(Z<1.4) = 1-0.9192433 = 0.08075666
Answer: P(snowfall>92.8) = 0.0808 (to four decimal places)
Derivatives:
cos --> -sin
sin ----> cos
f' = cost - sint
f ' (pi) = cos(pi) - sin(pi)
= -1 -0
= -1
