Answer:

<u><em>750 Books Per Year</em></u>

Step-by-step explanation:

For this problem, we will be using the standard Rate Of Change formula that we use for graphs:

<em>RoC = (y2 - y1) / (x2 - x1)</em>

y = books

x = year

By plugging in the given values:

RoC = (19000 - 16000) / (1999 -1995)

RoC = 3000 / 4

<u>RoC = 750</u>

VARVARA [1.3K]

Her IRA interest at the end of 30 years is mathematically given as

Interest= 438,765.56

<h3> IRA interest </h3>

Question Parameters:

  • N = 30
  • PV = 0
  • rate = 5%
  • FV = 800,000

Generally the equation for the payment function on excel is mathematically given as

A=PMT(rate, nper, pv, [fv], [type])

Therefore, inputting our functions

A=PMT(rate, nper, pv, [fv], [type])

where

A=PMT(5%, 30, 0, [800000], [])

A = 12,041.1481

Hence

interest = 800,000 - 30*12,041.1481

Interest= 438,765.56

Right now the number 33 and 89 to estimate their sum
ozzi

<span> <span><span>Addition, you can have 89 + 33 = 122 </span>
<span>Commutative Property by moving: 33 + 89 = 122
<span>Associative Property by grouping: (3 + 30) + (80 + 9 ) = 122 </span>
<span>Distributive Property by allotting: 10 (8.9) + 33 = 113   </span>


</span></span> Other examples include:
Addition, you can have 33 +  = 113 </span>
<span>Commutative Property by moving: 107 + 6 = 113 </span>
<span>Associative Property by grouping: (3 + 3) + (100 + 7 ) = 113 </span>
<span>Distributive Property by allotting: 2 (3) + 107 = 113   </span>

<span>Multiplication, you can have 6 x 107 = 642 </span>
<span>Commutative Property by moving: 107 x 6 = 642 </span>
<span>Associative Property by grouping: (3 + 3) x (100 + 7 ) = 642 </span>
