3 0

Answer:

2,087,000,000 583,000 3,000,000

Step-by-step explanation:

You're taking the decimal point of 2.087 and moving it to the right nine times, getting you 2,087,000,000.

The same applies to 5.83 x 10^5, moving the decimal point to the right five times, getting you 583,000.

3 x 10^6 -> 3,000,000

Find the area of the region bounded by the curves y= sin^-1(x/6), y=0, and x=6 obtained by integrating with respect to y. Your w
Ahat [919]
Check the picture below.

let's check where the quadratic and x = 6 meet, bear in mind we're integrating by "y", so

\bf y=sin^{-1}\left( \frac{x}{6} \right)\implies sin(y)=\cfrac{x}{6}\implies \boxed{6sin(y)=x}
\\\\\\
\begin{cases}
6sin(y)=x\\
x=6\\
y=0\\
x=0\leftarrow y-axis
\end{cases}\\\\
-------------------------------\\\\
6sin(y)=6\implies sin(y)=\cfrac{6}{6}\implies sin(y)=1\implies \measuredangle \boxed{y=\frac{\pi }{2}}
\\\\\\
6sin(y)=0\implies sin(y)=0\implies \to  \boxed{\measuredangle y=0\ ,\ \pi }

\bf -------------------------------\\\\
\displaystyle \int\limits_{0}^{\frac{\pi }{2}}\ [6-6sin(y)]dy\implies \left. \cfrac{}{} 3y^2+6cos(y) \right]_{0}^{\frac{\pi }{2}}
\\\\\\
\left[ \cfrac{3\pi 2}{4}+0 \right]-[0+6]\implies \cfrac{3\pi^2}{4}-6\approx 1.4022033

A triangle has three angles that measure 15 degrees, 85 degrees and (4x - 20). What is the value of x?
Lostsunrise [7]
180=15+85+(4x-20)
180-15-85=4x-20
80=4x-20
4x-20=80
4x=80+20
4x=100
x=100/4
x=25

the larger of two number is 15 more than three times the smaller number. If the sum of the two numbers is 63, find tge numbers.
irakobra [83]
X is the smaller number. 3x + 15 is the larger number. So x + 3x + 15 = 63. 4x + 15 = 63.
4x = 48. x = 12. (Smaller number) The larger 36 + 15 or 51.
