Answer:

Step-by-step explanation:
<u>Sinusoid</u>
The shape of a sinusoid is well-know because it describes a curve with a smooth and periodic oscillation. The sine and cosine are the two trigonometric functions in which the graph matches the description of a sinusoid. The sine can be identified because its value is zero at time zero.
The graph shown in the figure corresponds to a sine. The other characteristics of the sine function are
* It completes a cycle in
radians
* It has a maximum of 1 and a minimum of -1
* It's increasing for a quarter of the cycle, decreasing for half of the cycle, and increasing for the remaining quarter of the cycle
* The equation is

The function starts decreasing for the first quarter, which only is possible if the amplitude A is negative. We can also see the maximum and minimum values are 2 and -2 respectively. This means the amplitude is A=-2
We can also see the function completes 3 cycles in
radians or 6 cycles in
radians. Or, equivalently



Thus, the function can be expressed as

C - 0.17c = 0.83c
When you write “c” at the start, or x or whatever, it has an understood (invisible) number 1. So you’re subtracting the decimal on the next variable from 1.
ANSWER
C. 28
EXPLANATION
The given expression is

We want to evaluate this function at x=-2.
We just have to substitute x=-2 into the given expression.
In other words, we have to replace x with -2 wherever we see x in the expression

We evaluate the exponent to get

We multiply next to get:

We now add to obtain:

The correct answer is C
Answer: You would share in exactly 55 squares.
Step-by-step explanation: To solve this, you need to know how to convert, divide, and multiply.
10*10=100
100/n=20
n=5
11*5=55
SO, you shade in 55 squares.
Answer:
30%
Step-by-step explanation:
What is the percent decrease if the original price is $582 and it went down 30%
or decreased 30%
Check:
582 x 0.70 = 407.4
582-407.4=174.6
174.6/582= 0.3
