T_n = a_1 + (n - 1) d

<em>The sequence is:</em>
24, 31, 38,45, 52

<em>We can see from the sequence:</em>
a = 24, d = 7

<em>Find nth term:</em>
T_n = 24 + 7(n - 1)
T_n = 24 + 7n - 7
T_n = 7n + 17

<em>When  = 500,</em>
T_{500} = 7(500) + 17
T_{500} = 3517

Answer: 500th term is 3517

Aneli [31]

Answer:

181 mi^2

Step-by-step explanation:

Dimensions of large rectangle, on the left, are 6 mi by 8 m; area is 48 m^2;

Dimensions of small rectangle, in the middle of the diagram, are 4 mi by 5 mi, or 20 mi^2; area is 20 mi^2.

Dimensions of circle:  r = 12 mi; area of quarter circle is (1/4)(3.14)(12 mi)^2, or 113 mi^2.

Total area is 113 mi^2 + 20 mi^2 + 48 mi^2, or 181 mi^2

after 6 years what is the total anount of a compound intrest investment of $35,000 at 4% intrest compound quarterly
tangare [24]
The pertinent formula is    A = P (1 + r/n )^(nt), where
P is the original amount of money (Principal),
A is the compound amount,
r is the annual interest rate, expressed as a decimal fraction, 
n is the # of compounding periods per year, and 
t is the # of years.

Here,   A = $35000 ( 1 + 0.04/4)^(4*6)
                = $35000 (1.01)^24
                = $35000 (1.2697) =    $44440.71

In a study of automobile collision insurance costs, a random sample of n = 35 repair costs of front-end damage caused by hitting
laiz [17]

Answer: The maximum error = $105.76.

Step-by-step explanation:

Formula to find the maximum error:

E= z^*\dfrac{\sigma}{\sqrt{n}}

, where n= sample size.

\sigma = Population standard deviation

z*= Critical value(two-tailed).

As per given  , we have

\overline{x}=1438

n= 35

\sigma=269

For 98% confidence  , the significance level = 1-0.98=0.02

By z-table , the critical value (two -tailed) =z^* = z_{\alpha/2}=z_{0.01}=2.326

Now , the maximum error = E= (2.326)\dfrac{269}{\sqrt{35}}

E= (2.326)\dfrac{269}{5.9160797831}

E= (2.326)\times45.4692989044=105.761589252\pprox105.76

Hence, With 98% confidence level , the maximum error = $105.76.
