1. Identify the initial amount a and the rate of growth r (as a percent) of the exponential function y=350(1+0.75)^t . Evaluate the function when t=5 . Round your answer to the nearest tenth. a= __ r= __% when t = 5 , y = __

2. determine wether r (t) = 0.4 (1.06)^t represents exponential growth or exponential decay.
- this function represents; exponential decay, exponential growth, or neither growth nor decay
- identify the perent rate of change = __%

3. write a function in terms of t that represents the situation; your starting annual salary of 35,000 increased by 4% each year
y= __

4. identify the initial amount a and the rate of growth r (as a percent) of the exponential function y= 25 (1.2)^t. evaluate the function when t=5. round your answer to the nearest tenth.
a= ___ r=___ when t=5 , y= ___

5. write a function in terms of t that represents the situation. a population of 210,000 increases by 12.5% each year
y=

b. x + 1

step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
