8 0

Answer:

The exact area is 5\pi

Step-by-step explanation:

The area of the major circle is subtracted from the area of the minor circle (blank)

Major circle

r=\frac{6}{2} =3

A=\pi r^{2} =\pi (3)^{2} =\pi (9)=9\pi

Minor circle:

r=\frac{4}{2} =2

A=\pi r^{2} =\pi (2)^{2} =\pi (4)=4\pi

The shaded area:

9\pi -4\pi =5\pi

Hope this helps

\displaystyle\lim_{x\to\inty}(3x+1)^{4/x}=\lim_{x\to\infty}e^{\ln(3x+1)^{4/x}}=e^{\lim\limits_{x\to\infty}\ln(3x+1)^{4/x}}

\displaystyle\lim_{x\to\infty}\ln(3x+1)^{4/x}=\lim_{x\to\infty}\frac{4\ln(3x+1)}x\stackrel{\mathrm{LHR}}=\lim_{x\to\infty}\frac{4\frac3{3x+1}}1=\lim_{x\to\infty}\frac{12}{3x+1}=0

\implies\displaystyle\lim_{x\to\infty}(3x+1)^{4/x}=e^0=1

What are the solutions of the equation x4 – 5x2 – 36 = 0? Use factoring to solve.
pentagon [3]

Answer:

x=+/-3

Step-by-step explanation:

x^4-5x^2-36=0

factor

(x^2-9)(x^2+4)=0

split into 2 equations because one of these terms will need to equal zero for the eqation to be true

x^2-9=0              x^2+4=0

x^2=9                    x^2=-4

x=+/-3                    no real numbers

Statement 3: a+[c+(-c)]=b+[c(-c)]
Statement 4: a+0=b+0
<span>Statement 5: a=b. </span>
<span>What is the reason for Statement 2?
