Answer:

A=1000(1+\frac{0.023}{12})^{12t}

Rate of interest (r) = 0.19% monthly

Step-by-step explanation:

Given: The total amount of money in a saving account after t years.

A=1000(1.023)^t

Formula:

A=P(1+r)^t

Now we compare this formula with with given model.

P=1000

Rate of interest annually (r) = 0.023

Time = t

We need to change into monthly interest

New rate will divide by 12

New time will multiply by 12

r=\frac{0.023}{12}=0.0019

t=12\times t =12t

Function for monthly rate

A=1000(1+\frac{0.023}{12})^{12t}

Rate of interest (r) = 0.19% monthly

\text{Thus, Function Monthly interest rate: }A=1000(1+\frac{0.023}{12})^{12t}\text{ and Monthly Interest rate }= 0.19\%

Please find the fully simplified intercept form!!!! Will mark Brianliest !!!!!!!!!!!
photoshop1234 [79]

Answer:

  • y = -1/3x  - 8

Step-by-step explanation:

<u>Slope intercept form:</u>

  • y = mx + b

<u>Use two points from the graph:</u>

  • (0, -8) and (3, -9)

<u>The first point is the y-intercept: </u>

  • b = -8

<u>Find the slope using the slope formula:</u>

  • m = (y2 - y1)/(x2 - x1)
  • m = (-9 - (-8))/3 = -1/3

<u>The equation is:</u>

  • y = -1/3x  - 8

A car radiator needs a 80% antifreeze solution. The radiator now holds 15 liters of a 70% solutions. How many liters of this sho
slavikrds [6]
So... the radiator has 15 liters of 70% antifreeze.. but needs an 80% antifreeze

well, so, you need to drain some and put some with higher percentage, seems to be, you will end up at the same 15 liters, possible the radiator's capacity, of 80% antifreeze

so, the same amount going out, of 70% is the same amount going in, of 100% antifreeze

now.. let's use the decimal format for the percents, or 70% is 70/100 or 0.7 and so on
\bf \begin{array}{lccclll}&#10;&amount&concentration&&#10;\begin{array}{llll}&#10;concentration\\&#10;amount&#10;\end{array}\\&#10;&-----&-------&-------\\&#10;\textit{70\% sol'n, out}&x&0.7&0.7x\\&#10;\textit{100\% sol'n, in}&x&1.00&x\\&#10;\textit{current 70\% sol'n}&15&0.7&10.5\\&#10;-----&-----&-------&-------\\&#10;mixture&15&0.8&12&#10;\end{array}

so.. let's subtract, from the current solution, 0.7x and add 1x or x, our antifreeze concentration amount, should be 12 though

10.5 - 0.7x + x = 12

solve for "x"

Eliza started her savings account with $100. Each month she deposits $25 into her account. Determine the average rate of change
Afina-wow [57]
First, lets create a equation for our situation. Let x be the months. We know four our problem that <span>Eliza started her savings account with $100, and each month she deposits $25 into her account. We can use that information to create a model as follows:
</span>f(x)=25x+100
<span>
We want to find the average value of that function </span>from the 2nd month to the 10th month, so its average value in the interval [2,10]. Remember that the formula for finding the average of a function over an interval is: \frac{f(x_{2})-f(x_{1})}{x_{2}-x_{1} }. So lets replace the values in our formula to find the average of our function:
\frac{25(10)+100-[25(2)+100]}{10-2}
\frac{350-150}{8}
\frac{200}{8}
25

We can conclude that <span>the average rate of change in Eliza's account from the 2nd month to the 10th month is $25.</span>

Choose the best answer. The diagonals of a rectangle:
erastovalidia [21]

C.) Are the same length

<u>How you know-</u>

No matter how long the rectangle is the diagonals always will measure the same length. Think about two sides of a square, they have to equal the same length because if they were not the same then the shape wouldn't be a square.
