What is the perimeter of the rectangle? Write your answer in scientific notation. The area is 2.76 x 10 pw12
MrRa [10]
We know that
area of a rectangle=length*width
length=area/width
area=2.76 x 10^12 units²<span>
width=4.6 x 10</span><span>^5 units
</span>length=2.76 x 10^12/4.6 x 10^5 ------> 6 x 10^6 units

perimeter of a rectangle=2*[length+width]
width=4.6 x 10^5 units----> is equal to 0.46 x 10^6 units
length=6 x 10^6 units

perimeter of a rectangle=2*[6x10^6+0.46x10^6]----> 12.92 x 10^6 units

the answer is
12.92 x 10^6 units

Hello, could anyone please help me with my homework?
IRINA_888 [86]

Answer: See below

Step-by-step explanation:

100\left(\frac{1}{2}\right)^{\frac{t}{214}}=20

\mathrm{Divide\:both\:sides\:by\:}100

\frac{100\left(\frac{1}{2}\right)^{\frac{t}{214}}}{100}=\frac{20}{100}

Simplify

\left(\frac{1}{2}\right)^{\frac{t}{214}}=\frac{1}{5}

\mathrm{If\:}f\left(x\right)=g\left(x\right)\mathrm{,\:then\:}\ln \left(f\left(x\right)\right)=\ln \left(g\left(x\right)\right)

\ln \left(\left(\frac{1}{2}\right)^{\frac{t}{214}}\right)=\ln \left(\frac{1}{5}\right)

\mathrm{Apply\:log\:rule\:}\log _a\left(x^b\right)=b\cdot \log _a\left(x\right)

\ln \left(\left(\frac{1}{2}\right)^{\frac{t}{214}}\right)=\frac{t}{214}\ln \left(\frac{1}{2}\right)

\frac{t}{214}\ln \left(\frac{1}{2}\right)=\ln \left(\frac{1}{5}\right)

\frac{\ln \left(\frac{1}{2}\right)t}{214}=\ln \left(\frac{1}{5}\right)

\mathrm{Multiply\:both\:sides\:by\:}214

\frac{214\ln \left(\frac{1}{2}\right)t}{214}=214\ln \left(\frac{1}{5}\right)

-\ln \left(2\right)t=-214\ln \left(5\right)

\mathrm{Divide\:both\:sides\:by\:}-\ln \left(2\right)

\frac{-\ln \left(2\right)t}{-\ln \left(2\right)}=\frac{-214\ln \left(5\right)}{-\ln \left(2\right)}

t=\frac{214\ln \left(5\right)}{\ln \left(2\right)} or \mathrm{Decimal}:\quad t=496.89261\dots
