sin 30 = .5 and cos 60 = .5
sin 60 = sqrt(3) / 2 and cos 30 = sqrt(3) / 2
answer - cos 60 and cos 30
I also think the answer is D, who else agrees with me? Btw, thank you for posting this question. I enjoy answering fun things sometimes.
Answer:
what is this ?
Step-by-step explanation:
The formula given to us relates circumference with radius but we are given diameter instead. good thing we know that diameter is twice the length of radius so if diameter=28, the radius=14. therefore, using our formula, we can find the circumference:
C = 2(pi)(14)
C = 87.96
and this answer is close to 88 so the answer is A
let me know if you have any questions!!!
Answer:
y = x + 1
Step-by-step explanation:
We can see the line is linear so we can write the equation using y = mx + b. The components of the equation are m = slope and b = y-intercept. We can see from the graph that the y-intercept is 1 as the graph crosses the y axis at y = 1 and if we do 
or 
, we can plug in the y-intercept's coorinates and the point in red's coordinates to get the slope of 1. Therefore, the equation would be y = 1x + 1 or y = x + 1
