Step-by-step explanation:
(x,y) = P + (a)t
(x,y) = (4,7) + t(3,8)
(x,y) - (4,7) = t(3,8)
(x-4, y-7) = t(3,8)
Answer:
27
Step-by-step explanation:
The actual mean is 27.008333333333, round that as you will.
Answer: First option is correct.
Explanation:
Since we have given that
Radius = 11 inches
Height = 14 inches
Now, according to question, we have mentioned that all the dimensions of the cylinder is to be quadrupled i.e. four times.
Then,
Radius is given by

Height is given by

As we know the formula for " Volume of cylinder ":

Hence, our volume of new similar cylinder is 340426.24 cubic in.
Therefore, First option is correct.
I believe the answers are C. Acute (all angles less than 90 degrees) and E. Scalene (all 3 sides different values).
