Y= arcsin(x) is equivalent to sin(y) = x
we know that -1≤x+1, hence the range of y is: -π/2≤y≤+π/2
Area is trapezium =
A=1/2h(a+b)
84=1/2(6)(7+b)
84=3(7+b)
84=21+3b
3b=84-21
B=63/3
B= 21 cm
I’m sorry if my answer turned out to be wrong but I tried my best so best of luck !!
Answer:
cos 23 = x/7.8
Step-by-step explanation:
Horizontal translation: 2 units right.
Vertical translation: 5 units up
Stretch/compression: stretched by a factor of 3.
Reflection: not reflected.
2 pieces of squid = $3.50
Therefore 1 piece of squid = $1.75 (3.50÷2)
1 piece of eel = $3.25
3 pieces of tuna = $6.75
Therefore 1 piece of tuna = $2.25 (6.75÷3)
4 pieces of crab = $8.00
Therefore 1 piece of crab = $2 (8÷4)
Put them in order of price and you get
$1.75 , $2 , $2.25 , $3.25
squid,crab,tuna,eel
