Recognizing that the dotted line is sin(x) and solid line is cos(x), it's clear to see that the sin(x) has a larger amplitude than cos(x). So, we get a1 > a2.
Only B and E satisfies the above. But E is clearly incorrect since amplitude cannot be less than 0.
Therefore, B would be the correct choice.
Answer:
The last gearwheel would make 3 revolutions.
Step-by-step explanation:
The measure of the revolution of a gear per minute is referred to as the speed ratio. The speed ratio is the ratio of the speed of the driver gear to that of the driven gear, or ratio of the number of teeth of the driven gear to the number of teeth of the driver gear.
In the given question, the second and third gears are idlers. while the first is the driver and the fourth the driven.
The revolution of the last gearwheel can be determined by;
Speed ratio = 
= 
= 
Speed ratio = 1 : 3
The last gear would make 3 revolutions.
Answer:
10 sides, 114, for each interior angle, and 36 for each exterior angle.
Step-by-step explanation:
Since the sum of all exterior angle is 360 multiply by 4 which gets you 1140. Then we know that there are 8 sides to an octagon to find the sum of all the interior angles we can multiply the number of sides minus 2 by 180. Now knowing this we can do this for an octagon which gives us 1080. Since that is close to 1140 we can play around with the numbers and we will eventually go with the number 10 we minus this by 2 and multiply by 180 to get 1140. To find the measurement of 1 interior angle we would divide that number by the sides, so 1140 by 10 to get 114 for our 1 interior measurement. to get the 1 exterior measurement we would divide 360 by the number of sides which gives us 36 since the sum of all exterior measurements equals 360. I hope this helps.
Answer:
1 2/3.
Step-by-step explanation:
4 - 2 3/9
= 4 - 2 1/3
= 4 - 7/3
= 12/3 - 7/3
= 5/3
= 1 2/3
Y=4 is going to be the answer.
