The correct answer should be 95. I don’t know how you did it but try the PEMDAS method (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)
To see if it's a right triangle we need to determine if a²+b²=c²
(
)² + (
)² =
+
=
+
=
=
So it is a right triangle
Largest doll = 12 inches
2nd doll = (12) x 0.7
3rd doll = (12 x 0.7) x 0.7
4th doll = [(12 x 0.7) x 0.7) x 0.7
So, the height of the nth doll can be expressed as: 12 x 0.7^(n-1)
Example: 4th doll = 12 x 0.7^(4-1) = 12 x 0.7^3
Answer:
y = 2sinx + 2
Step-by-step explanation:
∵ y = Asin(Bx - C) + D
∵ D is the vertically shift
∵ It moves 2 units up
∴ D = 2
∴ y = 2sinx + 2
