Answer: 16700

Step-by-step explanation:

First, we must factor 167^2-167*67

Factoring out 167 gives:

167(167-1*67)

Following Order of Operations, you get 167(167-67) which then gets 167(100)

Then, multiply and get 16700

(k/3^k)(x-6)^k

enot [183]

$\displaystyle\sum_{k\ge0}\frac k{3^k}(x-6)^k$

converges by the ratio test for

$\displaystyle\lim_{k\to\infty}\left|\frac{\frac{k+1}{3^{k+1}}(x-6)^{k+1}}{\frac k{3^k}(x-6)^k}\right|=\frac{|x-6|}3\lim_{k\to\infty}\frac{k+1}k$

The limit is 1, so the series converges as long as

$\dfrac{|x-6|}3$

which indicates a radius of convergence of 3.

Mrs. Child bakes pumpkin pies using a deep‐dish pie plate with a 9 inch diameter. If she cuts her pies into 12 equal slices and

andrew11 [14]

Answer: $4.71\ in.$

Step-by-step explanation:

Given

diameter of pie is $d=9\ inch$

radius $r=\frac{9}{2}=4.5\ inch$

If child divides pie into 12 equal parts then each part subtends an angle of

$=\frac{360^{\circ}}{12}=30^{\circ}$ at the center

and crust length of single piece is

$=\frac{30}{360}\times 2\pi r$

$=\frac{1}{12}\times 2\times \pi \times 4.5$

$=2.35\ in.$

For two slice length is $2\times 2.35=4.71\ in.$

Thus the total length of crust eaten is $=4.71\ in.$

Which of the following correctly describes the sum of two rational numbers?

Elena-2011 [213]

Answer:

"The sum of two rational numbers is rational."

By definition, a rational number can be expressed as a fraction with integer values in the numerator and denominator (denominator not zero). So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.
