Well, you take a set of numbers and you find the biggest number and you subtract the smallest number from it. that is the mean and the mean is the average number.
Answer:
Find the coordinates of the point of intersection of the axis and the directrix of the parabola whose focus is (3,3) and directrix is 3x−4y=2. Find also the length of the latus-rectum.
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Using the Addition/ Subtraction formulae for cosine
Consider the left side
cos(x - y) - cos(x + y)
= cosxcosy + sinxsiny - (cosxcosy - sinxsiny) ← distribute
= cosxcosy + sinxsiny - cosxcosy + sinxsiny ← collect like terms
= 2sinxsiny = right side ⇒ proven
Answer:
4. 16.5 minutes 2508 words - Robert
5. 60 words (c)
6.I don't really know sorry :)
Step-by-step explanation:
4. 304 ÷ 2 = 1 minute 152 words - Robert
2508 ÷ 152 = 16.5 minutes 2508 words - Robert
5. 152 × 20 = 3040 words - Robert
483 ÷ 3 = 1 minute 161 words - Michaela
161 × 20 = 3220 words - Michaela
316 ÷ 2 = 1 minute 158 words - Laura
158 × 20 = 3160 words - Laura
= 3220 - 3160
= 60 words (c)
