Answer:
The amplitude is 3
Step-by-step explanation:
Given
The right function is:
Required
The amplitude
A sine function is represented as:
Where
By comparing:
and
So:
<em>Hence, the amplitude is 3</em>
40/16 = 24/x
16*24 = 384
x = 384 / 40
x =9.6
it cast a shadow 9.6 feet long
The second option is correct
(Most probably)
I'll do the 2d problem to show you how it's done; always remember your order of operations - PEMDAS (Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction).
6h - (9 - 3h) = 6 - 3(h + 2) Distribute what's in front of the parenthesis to the inside
6h - 9 + 3h = 6 - 3h - 6 combine like-terms on both sides
9h - 9 = - 3h Isolate the variable onto one side
12h = 9 Divide by 12 to get the variable alone
h = 9/12
-10x + 1 + 7x =37
-10x + 7x = 37 - 1
-2x = 36
X = 36 / -2
X = -18
Answer is x = -18
I think this is the answer
