Step-by-step explanation:
first of all
put above of equation
(sin/cos)(sin)+cos =sec
sin²/cos +cos=sec
take l.c.m
sin²+cos²/cos=sec
as sin ²+cos²=1 so
1/cos=sec
sec=sec
hence proved
Answer:
area of circle=pi times radius^2
diameter/2=radius
area of rectangle=length times width
rectanlge-circle=scarf
rectanlge=28 by 15=28*15=420
circle, diameter is 15 so radius is 15/2=7.5
area=pi7.5^2=pi56.25=3.14*56.25=176.625
so
rectangle-circle=420-176.625=243.375 square inches
the area of the scarf is 243.375 square inches
Step-by-step explanation:
Answer: 18600 feet
Step-by-step explanation:
f(t)=33600-1500t
f(t)=33600-1500(10)
f(t)=33600-15000
f(t)=18600
Answer:
8/-7
Step-by-step explanation:
using the equation: y₂-y₁/x₂-x₁
10-2/0-7 = 8/-7
