The formula for simple interest is A = P(1+rt)

Where P is the principal ( amount of money deposited)

R is the interest rate

t is the amount of time

A is the total of the principal and interest.


Using the information given in the problem:

A = 4200(1+0.0325*3)

A = 4200(1 + 0.0975)

A = 4200(1.0975)

A = 4609.50


Now subtract the principal from the total to find the amount of interest:


4609.50 - 4200 = 409.50


Amount of interest = $409.50

How do u do number 2???
Mila [183]

Answer:

The answer is C.

Step-by-step explanation:

Well all you have to do is plug in X for the X, and Y for the Y.

So for C it says y= -5x+27 and you plug in (6, -3). X is 6. Y is -3. It would be

-3= -5(6) +27

-3= -30+ 27

-3= -3

In the coordinate plane, two vertices of square ABCD are A (0,0) and B (0, m). What are the coordinates of points C and D? Do no
Sonbull [250]

Answer:

Step-by-step explanation:

As shown in the graph,

A, B, C and D are the vertices of a square, all sides of the square will be equal in measure.

Coordinates of A → (0, 0)

Coordinates of B → (0, m)

Distance between point D and point A = m

Therefore, coordinates of point D → (m, 0)

Now point C will be equally distant from the points B and D.

Coordinates of C → (m, m)

Find the point on the x-axis that is equidistant from the points (−3,−1) and (1,6)
Klio2033 [76]

well, we'll be using the distance formula twice here.

that point, is on the x-axis, what's the value of "y" at the x-axis?  well y = 0, since it's way down at the 0 level, so the point must be (x , 0).

the distance then from (x,0) to (-3,-1) is the same distance as from (x,0) to 1,6).

\bf \begin{array}{rcllll} \stackrel{\textit{distance from (x,0) to (-3,-1)}}{\sqrt{(-3-x)^2+(-1-0)^2}}&=&\stackrel{\textit{distance from (x,0) to (1,6)}}{\sqrt{(1-x)^2+(6-0)^2}} \\\\\\ (-3-x)^2+(-1-0)^2&=&(1-x)^2+(6-0)^2 \\\\\\ 9+6x+x^2+1&=&1-2x+x^2+36 \\\\\\ x^2+6x+10&=&x^2-2x+37 \end{array} \\\\\\ 6x+10=-2x+37\implies 8x+10=37\implies 8x=27 \\\\\\ x = \cfrac{27}{8}\implies x = 3\frac{3}{8}~\hfill \blacktriangleright \left( 3\frac{3}{8}~,~0 \right) \blacktriangleleft
