Hello there! As far as we can see, the y-intercept is 2. Going up 2 helps move the line up by 2. We can go ahead and eliminate C, because that equation only goes up one, and D, because we don't go down any. We have the points (1, 3) and (2, 4). We add the x-value and we can see that 1 + 2 is 3 and 2 + 2 is 4. The only equation that fits the line at all is A. Therefore, the answer is A.
Cos x = -12/13
sin x = -sqrt(13^2 - 12^2) / 13 = -5/13
tan x = 5/12
tan x/2 = (1 - cos x) / sin x = 1 - (-12/13) / -5/13 = 25/13 * -13/5 = -5
2sin^2 x/2 = 1 - cos x = 1 - (-12/13) = 25/13
sin^2 x/2 = 25/13 / 2 = 25/26
sin x/2 = 5/√26
sin x/2 / cos x/2 = tan x/2
cos x/2 = sin x/2 / tan x/2 = 5/√26 / -5 = -1/√26
sin x/2 = 5/√26
cos x/2 = -1/√26
tan x/2 = -5
Answer:
180 km
Step-by-step explanation:
3/5 times 300 is 180
Answer:
13
Step-by-step explanation:
Given:
- Square stickers that were 3/4 in long
- The spine is 10 and 1/2 in long
If she laid the stickers side by side without gaps or overlaps so the number of sticker to cover the length of the spine:
10 : 
≈13
She needs 13 stickers cover the length of the spine
