Answer:
units or 14.2 units (rounded to the nearest tenth)
Step-by-step explanation:
To find the distance between a pair of two points, use the distance formula 
. Substitute the x and y values of (-1,-2) and (8,9) into the formula and simplify:
So, as an exact answer, the distance is units.
(To find the decimal approximate of that answer, enter it into a calculator. This would make the decimal approximate 14.2 units, when rounded to the nearest tenth.)
Answer: I honestly have no clue
Step-by-step explanation:
True!
The surface area of a cylinder is:
SA = 2πr² + 2πrh
r = 1 in
h = 4 in
π = 3.14
SA = 2 * 3.14 * 1² + 2 * 3.14 * 1 * 4
= 6.28 + 25.12
= 31.4 in²
A: is 14
B: is 10-14=-4
C:-27+-15=-42
-42+100=58.
7800 because it grows 300 per 2 hours so 3000 + 4800 = 7800
