1. (a) Use the integral test to show that P[infinity] n=1 1/n4 converges. (b) Find the 10th partial sum, s10, of the series P[in

scZoUnD [109]

Answer:

Step-by-step explanation:

a) $\int\limits^{\infty} _1 {\frac{1}{n^4} } \, dn\\ =\frac{n^{-3} }{-3}$

Substitute limits to get

= $\frac{1}{3}$

Thus converges.

b) 10th partial sum =

$\int\limits^{10} _1 {\frac{1}{n^4} } \, dn\\ =\frac{n^{-3} }{-3}$

= $\frac{-1}{3} (0.001-1)\\= 0.333$

c) Z [infinity] n+1 1 /x ^4 dx ≤ s − sn ≤ Z [infinity] n 1 /x^ 4 dx, (1)

where s is the sum of P[infinity] n=1 1/n4 and sn is the nth partial sum of P[infinity] n=1 1/n4 .

Lelechka [254]

Answer:

C = 25 + 3n

Step-by-step explanation:

Andre has a summer job selling magazine subscriptions.

We are told that:

Andy earns $25 per week plus $3 for every subscription he sells.

Let us represent

C = Total amount of money he makes this week

n = the number of magazine subscriptions Andre sells this week.

Hence, Our Algebraic expression =

C = $25 + $3 × n

C = 25 + 3n

Margie babysits for two families. Mr. and Mrs. Smith pay her $6.50 an hour to babysit their son, Shea. Mr. and Mrs. Jones pay Ma

rodikova [14]

Answer:

A) $\$ 6.5\timesx$ is the expression to represent total amount of money she earns babysitting for Smith family.

B) $\$45.5$ she will earn for Smith family for 7 hours

C) It would take $12 \ hrs$ for Margie to make $\$78$ when babysitting for the Smith family

Step-by-step explanation:

Given.

Mr. and Mrs. Smith pay Margie $\$6.50$ an hour to babysit their son, Shea.

Mr. and Mrs. Jones pay Margie $8 an hour to babysit their children, Sarah, Susan, and Dawn.

Let x be number of hours.

Solving for Part A.

Amount of Money earn from Smith family = Pay per hour $\times$ Number of hours = $\$ 6.5 \times x= \$ 6.5x$

Solving for Part B.

x=7

Margie earns from smith family for 7 hours = $\$ 6.5x=\$6.5\times7=\$45.5$

Solving for part C.

Margie earned = $\$ 78$

To find number of hours

No of hour Margie has done babysitting for Smith family $x=\frac{\$78}{\$6.5}=12 \ hrs$
