Answer:
Four (4) pounds
Step-by-step explanation:
Because we required two (2) pounds to stretch the spring eight (8) inches, we need double the force to stretch it sixteen (16) inches. Sixteen is just double the original amount, meaning we need four (4) pounds to stretch the spring sixteen inches.
Hope this helps!
20 Cars on the bridge
60% of 20 ＝ 12 Passenger Car
12×1.00＝$12
20-12＝8 Other Vehicles
8×2.75＝$22
12+22＝$34
So expected revenue is $34

Step-by-step explanation:
0.7S + 0.5L <u><</u> 11
0.7S + 0.5(10) <u><</u> 11
0.7S + 5 <u><</u> 11
0.7S <u><</u> 6
6 ÷ 0.7 = 8.5
Answer:
sin(t) = √15/4,
cos(t) = - 1/4,
tan(t) = - √15
Step-by-step explanation:
The coordinates of the terminal point P(x, y) determined by t are x = - 1/4, and y = √15/4;
sin(t) = y = √15/4
cos(t) = x = - 1/4
tan(t) = y/x = √15/4 / - 1/4 = - √15
