Step-by-step explanation:
They are saying that F(d)=110+0.12d.
D stands for the meters climbed
so 110 is the fixed fee and 0.12 is the increase in price every meter.
100 times 0.12 is 12

Step-by-step explanation:
L.H.S=(1-cosB)(1+cosB)
=(1-cos^2B). {using (a+b) (a-b)=(a^2-b^2)in second step}
=sin^2B
=1/cosec^2B
Therefore,L.H.S=R.H.S proved
Answer:
Step-by-step explanation:
<u>Formula is given</u>
<u>If C = 15 yd, π = 3.14, then r is</u>
- C = 2πr
- r = C/2π
- r = 15/(2*3.14) = 2.39 yd rounded to the nearest 100th
A good rule is to change 10 to 15 percent of the water each week. If your tank is heavily stocked, bump that up to 20 percent each week. A lightly stocked aquarium can maybe get by for two to four weeks, but this should be the maximum length of time between water changes.
