Answer:
nice question you asked me dear
Answer:
d
Step-by-step explanation:
The answer must have a negative slope because the graph is decreasing.
The y-intercept is 10. The equation must have +10 at the end.
y = -3x + 10
1. cylinder to cone:
(πr^2h)/((1/3)πr^2h) = 3:1
2. sphere to cylinder:
((4/3)πr^3)/(πr^2h) = 4r:3h
3. cone to sphere:
((1/3)πr^2h)/((4/3)πr^3) = h:4r
4. hemisphere to cylinder:
half the ratio of sphere to cylinder = 2r:3h
Answer:
131
Step-by-step explanation:
Using proportion,
If Out of 550 calculators = 6 are defective,
Then out of 12000 calculators = ? are defective
= 21.8 * 6
= 130.8 ≈ 131
∴ Approximately 131 calculators are defective
Answer:
An important use of the dot product is to test whether or not two vectors are orthogonal. Two vectors are orthogonal if the angle between them is 90 degrees. ... Thus, two non-zero vectors have dot product zero if and only if they are orthogonal.
