Fnet=mass * acceleration
=150kg* 10= 1500N
Answer: £30.31
Explanation:
100/140 minutes of calls were free. Then, 40 x .09, which is 3.6
61 non-free texts, costing 11p each. So... 61 x .11 = 6.71
Add those together, with 20.
Answer:
None of the above
Step-by-step explanation:
7/10=70/100
(-5+-√25-4(-4.9)(9))/-9.8
(-5+-√25+19.6(9))/-9.8
(-5+-√25+176.4)/-9.8
(-5+-√201.4)/-9.8
(-5+-14.9)/-9.8
-19.9/-9.8
t=2.4
9.9/-9.8
t=-1
Time can't be negative, so time is approximately 2.4
Answer:
<em>A) The reference angle should be </em><u><em>
,</em></u><em> and the sign of the value should be </em><u><em>negative.</em></u>
Step-by-step explanation:
cos(
)
Remove full rotations of 2π until the angle is between 0 and 2
.
cos(
)
Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the third quadrant.
-cos()
The exact value of cos() is 
.
