That would be tan
(1-cos)(1+cos)=1-cos² which equals to sin²
√sin²/cos²= sin/cos which equals to tan
Very good job! They are all correct and it shows how you got the answer! ^_^ 100%
Answer:
B (3, 13.5)
Step-by-step explanation:
Using point (0,0) and (15, 67.5) we can find the slope(gradient).
(y - y¹) / (x - x¹) = (67.5 - 0) / (15 - 0)
= 67.5 / 15 = 4.5
slope = 4.5
using the point given in option A (0, 4.5) with point (15, 67.5) to calculate the slope it gives 4.2 which is not equal to what we calculated.
using the option B (3, 13.5) with (15, 67.5) gives a slope of 4.5 which is equal to the slope of the line.
Answer:
188 legs
Step-by-step explanation:
A game of legs!!
In this question, we are asked to calculate the number of legs of animals present in the question.
Let’s first identify the individual brands of animals present. We have ;
4 dogs, 7 bees, 5 cockroaches, 8 spiders, 3 deers, 4 boars and 2 antlers.
A dog has 4 legs; this means total number of legs contributed by the dogs to the pool will be 4 * 4 = 16 legs
A bee has six legs; total number of bees legs is thus 7 * 6 = 42 legs
A cockroach has 6 legs; total number of cockroaches legs is 6 * 5 = 30 legs
8 spiders have a total of 8 * 8 = 64 legs
3 deers, 4 boars and 2 antlers have 4 legs each making a total of 9 * 4 = 36 legs
The total number of legs present is thus; 36 + 64 + 30 + 42 + 16 = 188 legs
30cm
First you want to add the decimals 9.5 and6.5 so you get 16 then you add the other 14 cm to get a total of 30
