The answer would be D because triangles add up to 180 degrees and the two angles together only add up to 140, so the missing angles would be 40 degrees
The answer is 47 and cows cows like 47 in a way that cows like 47. it could also be blue or red or 13 or 27 have fun guessing
Answer:
By using the 90 degree clockwise rotation formula, we are able to determine that the answer is (7, 6)
Step-by-step explanation:
The formula for 90 degree clockwise rotation is
(x,y)--->(y,-x)
The reason why our -6 turns into a positive is because the negative was replacing that negative therefore making it positive.
Hope this helps!
I'll leave the rest of the formulas I have in my notes for you!
180 degree rotations
(x,y)--->(-x,-y)
90 degree counterclockwise
(x,y)--->(-y,x)
270 degree rotation
(x,y)--->(y,-x)
Answer:
32.3m
Step-by-step explanation:
Use equation A = Ao(0.5)^(t/t½)
Now input values: 40 = 980(0.5)^(t/7)
rearrange for t: t = [7ln(2/49)]/ / ln(0.5). Then from here, you can extract 32.3 as your answer
