Answer:
d. 42
Step-by-step explanation:
PEDMAS
We do brackets first, so:
4 + 4 = 8
Then multiplication,
5 x 8 = 40
Then addition
40 + 2 = 42
Step-by-step explanation:
the formula to calculate a circumference is
(consider x as the diameter)
so I'll be noting the circumference as C alongside the circle's ranking
a.
b.
c.
hope I helped
Answer:
3/-1
Step-by-step explanation:
The slope is 3/-1 (Rise 3 on the y axis, run to the negatives by 1 on the x axis)
To find the slope of two points, use the formula of y2-y1/x2-x1 (For example, with this equation it would be 10-4/10-12)
I'm not sure what it means to interpret the slope, but hopefully this helped you!
Answer:
a+b
Step-by-step explanation:
=1a+1b
=1(a+b)
=a+b
Cot x = cos x / sin x
cot π/4 = cot 45° = cos 45° / sin 45°
We know that sin 45° and sin 45° have the same value:
cos 45° = sin 45° = √2 / 2;
cos 45° / sin 45° = √2/2 : √2/2 = 1
Answer:
cot π/4 = 1
