What is an equation of the line that passes through the point (4,-3)(4,−3) and is perpendicular to the line 4x+y=34x+y=3?
zlopas [31]

Step-by-step explanation:

Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

4x+ y= 3

y= -4x + 3

slope = -4

the new slope = 1/4

the equation formula y= mx+b

m = new slope

y = (x/4) + b

From the point given (4,-3)

y = -3. x = 4

-3 = 1 + b

b = -4

the equation =

y =  \frac{1}{4} x - 4

$1210 is invested in an account earning 11.5% interest compounded monthly. What is the balance at the end of 13 years? Group of
kap26 [50]

Answer:

Final amount = $5357.52

Step-by-step explanation:

Formula to be used,

Final amount = \text{Initial amount}\times (1+\frac{r}{n})^{nt}

Here, n = number of compounding in a year

t = Duration of investment

Now we substitute the given values in the question.

Final amount = 1210(1+\frac{0.115}{12})^{12\times 13}

                      = 1210(1.009583)^{156}

                      = 1210(4.4277)

                      = $5357.52
