Answer:
cos²x.sec²x =1 (formula)
cos and sec are reciprocal to each other
cos²x=1/sec²x
now from the eq above,open the brackets and multiply
1-cos²2x
sin²2x
Answer:
2 * 50/(y + 8)
Step-by-step explanation:
"twice the quotient of 50 and a sum of a number y and 8"
y + 8
"twice the quotient of 50 and a sum of a number y and 8"
50/(y + 8)
"twice the quotient of 50 and a sum of a number y and 8"
2 * 50/(y + 8)
Property of equality
k=k
10/2=5
5=5
We know that
[LA]=pi*r*l
where
LA is the lateral area of the cone
r is the radius
l is the slant height
l=LA/(pi*r)
r=15.1 cm
LA=555*pi cm²
l=(555*pi)/(pi*15.1)----> l=36.75 cm
the answer is
the slant height is 36.75 cm
