Use the distance formula to find the distance between the points (−10,−9) and (−3,8).
1 answer:
Step-by-step explanation:
the distance can be seen as Hypotenuse of a right-angled triangle with its legs being the x and y coordinate differences.
so, we use Pythagoras
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90 degree angle).
distance² = (-10 - -3)² + (-9 - 8)² = (-7)² + (-17)² = 49+289 =
= 338
distance = sqrt(338) = sqrt(2×169) = 13×sqrt(2) =
= 18.38477631...

Answer:
2.25 cm³
Step-by-step explanation:
The volume of a pyramid can be found using the formula:
Base area
= area of square
= side ×side
= 1.5²
= 2.25 cm²
Volume of paperweight
= ⅓(2.25)(3)
= 2.25 cm³
