A quantity with an initial value of 160 grows continuously at a rate of 0.65% per hour.
dangina [55]

Answer:

167.10

Step-by-step explanation:

Here, we write out the general form for an exponential equation;

y = I (1 + r)^n

where y is the current value which we want to calculate

I is the initial value which is 160

r is the growth rate = 0.65% = 0.65/100 = 0.0065

402 minutes to hours will be 402/60 = 6.7 hours which is n

Substituting these values, we have

y = 160( 1 + 0.0065)^6.7

y = 160(1.0065)^6.7

y = 167.10

Tonya plans to join a fitness club. She researched the costs to join different clubs in her area and found that there is a linea
Ne4ueva [31]

Answer: 1 club - Club 2

Step-by-step explanation:

You can find the monthly rates by deducting the cost at 12 months from the cost at 24 months and dividing it by 12.

Club 1                                         Club 2                                 Club 3

= (432 - 216) / 12                       = (390 - 210) / 12                 = (504 - 252) / 12

= $18                                          = $15                                   = $21

Multiply these rates by 6 months and any club total cost at 6 month that differs from your answer has a joining fee.

Club 1;                                          Club 2;                                 Club 3

= 18 * 6                                         = 15 * 6                                = 21 * 6

= $108                                          = $90                                  = $126

<em>Same as total cost at              </em><u><em> Joining fee of $30</em></u><em>;      </em>         <em>No joining fee as </em>

<em>6 months so no joining            120 - 90 = $30                      this is the same </em>

<em>fee.                                                                                           as total cost at 6 </em>

<em>                                                                                                 months.</em>
