Answer:
5) arccos A = 28°
6) arcsin A = 53°
Step-by-step explanation:
5) cos A = 30/34
6) sin A = 32/40
Answer:
0/13 This is a zero slope
Step-by-step explanation:
y2-y1/x2-x1
if the number in the numerator is a zero, it is a zero slope. if the zero is in the denominator it is undefined
trick for remembering zero slope vs undefined: if the zero is UNDEr it is UNDEfined- this makes more sense if you say it out loud ;)
Answer:
x = -2/3 or 4/5
Step-by-step explanation:
-15r^2 + 2r + 8
Point G(4, -2)
Point H(-1, 10)
We want the distance of line segment GH.
Use the distance formula for points.
Note: d(G, H) means the distance from point G to point H.
d(G, H) = sqrt{(10 -(-2))^2} + (-1 -4)^2
d(G, H) = sqrt{(12)^2 + (-5)^2}
d(G, H) = sqrt{144 + 25}
d(G, H) = sqrt{169}
d(G, H) = 13
