Sin 3pi/4 is angle 135 degrees or 45 degrees below 180 degrees. Hence it's opposite side is 1 and adjacent is 1, implying the hypothenus is sqrt(2). Hence
Sin 3pi/4 = 1/sqrt(2). Now multiply by sqrt(2)/sqrt(2) to get:
[1/sqrt(2).] * [sqrt(2)/sqrt(2)] = sqrt2)/2
Y=5x+7
The slope-intercept equation is y=mx+b, m is the slope and b is the y intercept.
Answer:
Step-by-step explanation:
<u>Surface area, 4 faces only, excluding the area of the base:</u>
- A = 4*(1/2*12*20) = 480 m²
<u>Total surface area, including the base:</u>
<h3><u>
The value of the number is equal to 16.</u></h3>
7x + 8 = 120
<em><u>Subtract 8 from both sides.</u></em>
7x = 112
<em><u>Divide both sides by 7.</u></em>
x = 16
Just find a calculator and just type the converted decimals:
490 divided by 3.5
