Answer:
Horizontal component = 9.6
Step-by-step explanation:
Recall that the horizontal component is given by the cosine projection;

which in our case (using the fact that in each degree of angle one has 60 minutes of angle, and therefore 30 minutes of angles is the same as 0.5 degrees) becomes:

And rounding to the nearest tenth as requested, we have:

Would it be 33/10? If you are multiplying and then division you would use the inverse of the divided fraction and multiply. So you could invert 2/5 to 5/2 and add to 4/5. After finding the common denominator it would be adding 8/10 + 25/10 = 33/10.
The first one A 7/2
You can just round up 6.75 -> 7 and 1.67->2
Answer:
8.1 , 8.2, 8.3, 8.4 , 8.5, ............. etc.
Answer:
Mr. Mole is descending by 2.4 meters per minute
Step-by-step explanation:
Let
x ----> the time in minutes
y ---> the distance in meters
we know that
In this problem the rate of change or slope is the same that the speed
The formula to calculate the slope between two points is equal to

take two points from the table
(5,-18) and (8,-25.2)
substitute the values in the formula

---> is negative because is descending
