Take out common factor 3:
Factorise (x² - 1):
Answer:
Step-by-step explanation:
By applying Pythagoras theorem in the triangle given in the picture,
(Hypotenuse)² = (leg 1)² + (leg 2)²
PO² = (15)² + 8²
PO² = 225 + 64
PO = √289
PO = 17
By applying sine rule in the given triangle,
sin(x°) =
=
cos(y°) =
Relation between the ratio of sin(x) and cos(x) will be,
=
=
There could be five in each class.
Answer:I don’t think so since 5/8 is closer to a whole but 61%=61/100 seems bigger
Step-by-step explanation:
Volume of a cylinder= π r² h
r= 5ft
h= 15ft
V= π (5²)(15)
V= π(25)(15)
V= 375π ft³ ≈ 1178.10 ft³
Answer:
The volume is about 1178.10 cubic feet.
