scoray [572]

Answer:

$1545.65.

Step-by-step explanation:

We have been given that Victor has a credit card with an APR of 13.66%, compounded monthly. He currently owes a balance of $1,349.34.

To solve our given problem we will use compound interest formula.

$A=P(1+\frac{r}{n})^{nt}$ , where,

A = Final amount after t years,

P = Principal amount,

r = Interest rate in decimal form,

n = Number of times interest is compounded per year,

t = Time in years.

Let us convert our given interest rate in decimal form. $13.66=\frac{13.66}{100}=0.1366$

Upon substituting our given values in compound interest formula we will get,

$A=1,349.34(1+\frac{0.1366}{12})^{12*1$

$A=1,349.34(1+0.011383333)^{12$

$A=1.349.34(1.011383333)$

$A=1,349.34*1.145485275522$

$A=1,545.64910167397$ ≈ $ $1545.65$

Therefore, Victor will owe an amount of $1545.65 after one year.

A rhombus has coordinates A(-6, 3), B(-4, 4), C(-2, 3), and D(-4, 2). What are the coordinates of rhombus A′B′C′D′ after a 90° c

Liula [17]

We are given that the coordinates of the vertices of the rhombus are:
A(-6, 3)
B(-4, 4)
C(-2, 3)
D(-4, 2)

To solve this problem, we must plot this on a graphing paper or graphing calculator to clearly see the movement of the graph. If we transform this by doing a counterclockwise rotation, then the result would be:
A(-6, -3)
B(-4, -4)
C(-2, -3)
D(-4, -2)

And the final transformation is translation by 3 units left and 2 units down. This can still be clearly solved by actually graphing the plot. The result of this transformation would be:

A′(6, -8)
B′(7, -6)
C′(6, -4)
D′(5, -6)

Find the value of x that will make a||b help ?

nydimaria [60]

Answer:

x=30

Step-by-step explanation:

Find the value of x that will make A and B parallel

For A & B to be parallel, the interior angles must be supplementary, i.e.

4x+2x = 180

6x=180

x=30

When x=30, the interior angles are 120 and 60 which are supplementary.
