Step-by-step explanation:
<u>Step 1: Define</u>
-1.6 - 2x = 5x + 0.9
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 2x on both sides: -1.6 = 7x + 0.9
- Subtract 0.9 on both sides: 2.5 = 7x
- Divide 7 on both sides: 0.357143 = x
- Rewrite: x = 0.357143
Answer:
The altitude is changing at a speed of 200 √3 km/hr
Step-by-step explanation:
Here, we want to know how far the altitude of the plane is changing
we are told that the airplane makes an angle of 60 degrees with the ground
So therefore , the rate of change of its altitude will be ;
sin 60 = x/ 400
x = 400 sin 60
x = 400 * √3/2
x = 200 √3 km/hr
+ The volume of each candle is : 6*5*14= 420 cm³
+ The company used 4620 m³, so we have 4620:420= 11 candles
That is for you, 11 candles
Ii would have to go with 25m to the second power so b
