How long will it take for $6400 to grow to $43,800 at an interest rate of 3.4% if the interest is compounded continuously?

andrew-mc [135]

Answer:

57.53years to the nearest hundredth

Step-by-step explanation:

For compound interest,A=P(1+r/100)^t

where r=rate of interest

t= investment tenor

$43800=6400(1+3.4/100)^t

which simplifies to 57.5250≈57.53 to the nearest hundredth

Choose the correct range for the quadratic function?

Ray Of Light [21]

Answer:

$-2 \le y < \infty$

Step-by-step explanation:

The range is the set of values of the y-coordinates of all the points in the function.

We see in the graph that the lowest y-coordinate is -2. The graph goes up from -2 on both sides all the way to infinity. The range is -2 and all values greater than -2.

Answer: $-2 \le y < \infty$

What is the zero in the quadratic function f(x)= 9x^2-54x-19?

Alex17521 [72]

Answer:

6.33... and 0.333...

Step-by-step explanation:

The quadratic formula is

$x=\frac{-b+\sqrt{b^2-4ac} }{2a}$ .

It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions. Using the formula will require less work than finding the factors if factorable. We will substitute a=9, b=-54 and c=-19.

$x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}\\x=\frac{-(-54)+/-\sqrt{(-54)^2-4(9)(-19)} }{2(9)}\\x=\frac{54+/-\sqrt{2916+684} }{18}$

We will now solve for the plus and the minus.

The plus,,,

$x=\frac{54+\sqrt{3600}}{18}\\x=\frac{54+60}{18}\\x=\frac{114}{18}\\x=6.3$

and the minus...

$x=\frac{54-\sqrt{3600}}{18}\\x=\frac{54-60}{18}\\x=\frac{-6}{18}\\x=-0.333...$

Ahmad deposits $3000 into an account that pays simple interest at a rate of 3% per year. How much interest will he be paid in th

Sonja [21]

Answer:

.......

Step-by-step explanation:

Jahlan, simple interest means that interest is paid every year on the original $4000.

To find 2% of 4000, you multiply 4000(.02) = $80.

Since the interest is the same, 3(80) = $240.
