Dalia Ramirez Anchondo deposits $ 200 into her savings annuity every paycheck. She gets paid weekly. The credit union will pay Dalia 4% compounded quarterly. What is the future value of Dalia in 4 years. Help me

$41,418.96‬

Explanation:

There are four quarters in a year and the interest rate is a yearly rate that should be converted to a quarterly rate:

= 4% / 4

= 1%

Delia gets paid $200 a week. There are 12 weeks in a quarter so the quarterly contribution is:

= 200 * 12

= $2,400

The number of quarters she invests is:

= 4 * 4years

= 16 quarters

As this payment is constant, it is an annuity.

Value after 4 years will be:

= Annuity * Future value interest factor of annuity, 1%, 16 periods

= 2,400 * 17.2579

= $41,418.96‬

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
