Answer:
2.5, 5, 7.5
Step-by-step explanation:
Count.
Step-by-step explanation:
tanB + cotB = (sinB)/(cosB) + (cosB)/(sinB)
= (sin2B + cos2B)/[(cosB)(sinB)]
= 1/[(cosB)(sinB)]
= (1/cosB)(1/sinB)
= (secB)(cscB)
Answer:
(
2
,
8
)
Explanation:
Two lines are parallel if they share the same slope.
Any line parallel to
y
=
10
x
will have the slope 10.
Now, we have:
y
=
3
x
2
−
