The value of his investment at the third year is
F (3)=300×(1.02)^(3)=318.36

The value of his investment at the fifth year is
F (5)=300×(1.02)^(5)=331.22

The average rate of change of the value is
(331.22−318.36)÷2 years=6.43 per year

prisoha [69]

Answer:

Less than $12

Step-by-step explanation:

I changed everything into decimals to make it easier to solve:

1 2/5= 1.4

2 3/10= 2.3

1.4+2.3=3.7

2.99·3.7=11.063 (Round it to the nearest hundredth and you get 11.06)

Expand . ( 3x –2 ) 2 please help me with this.
Ainat [17]

-------------------------------------------------------------------------------------------------------------

Answer:  \textsf{9x}^2\textsf{ - 12x + 4}

-------------------------------------------------------------------------------------------------------------

Given:  \textsf{(3x - 2)}^2

Find: \textsf{Simplify the expression}

Solution:  It looks like 2 is at the end of the parenthesis where the power would be instead of distributing the number.  If so the following steps would be followed.

<u>Expand</u>

  • \textsf{(3x - 2)}^2
  • \textsf{(3x - 2)(3x - 2)}
  • \textsf{(3x * 3x) + (3x * (-2)) + (3x * (-2)) + (-2 * (-2))}

<u>Simplify</u>

  • \textsf{9x}^2\textsf{ - 6x - 6x + 4}
  • \textsf{9x}^2\textsf{ - 12x + 4}

Therefore, after following the provided information we are able to determine that the expanded form would be 9x^2 - 12x + 4.

Write an equation in slope intercept form for the line that passes through (-6,-2) and has a slope of 1/3
BabaBlast [244]

Answer:

y=1/3x-2

Step-by-step explanation:

Since the slope intercept form formula is y=mx+b all we need to do is input the values. So m is the slope. Input 1/3. X is next to it because we solve for this. B is the y intercept. Meaning its the point that crosses the line on the graph that is vertical. And you already have -2. Since we know: (x,y) so choose the y. And you have your equation.

Hope this helps!! If so please mark brainliest and rate/heart to help my account if it did!!
