Question 10

vazorg [7]

Answer:

$83,320

Step-by-step explanation:

The formula to apply here is;

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

where;

A=Amount at the end

P=the amount to invest/principal

r=rate of interest as a decimal

n=number of compoundings in a year

t=time in years

Given that;

A=$400,000

P=?

r=8%=0.08

n=2

t=20

Substitute values in equation

$A=P(1+\frac{r}{n} )^{nt} \\\\\\400,000=P(1+\frac{0.08}{2} )^{2*20} \\\\\\400,000=P(1+0.04)^{40} \\\\\\\\400,000=P(1.04)^{40} \\\\\\400,000=P(4.80102062794)\\\\\\\\\frac{400,000}{4.80102062794} =\frac{4.80102062794P}{4.80102062794} \\\\\\83315.617=P\\\\$

P=$83,320 (to the nearest dollar)

Perform the specified operations on the polynomials: Subtract 2x2−3xy+4y2from 3x2−5xy−6y2

tankabanditka [31]

Answer:

Solution to the given expression is $(x^2 -10y^2 -2xy)$

Step-by-step explanation:

Here, the given expression are:

$P(x) = 2x^2- 3xy+4y^2\\Q(x) = 3x^2 - 5xy-6y^2$

To Solve for : Q(x) - P(x)

Now substitute the value of P(x) and Q(x) , we get:

$Q(x) - P(x) = P(x) = (3x^2 - 5xy-6y^2) - (2x^2- 3xy+4y^2)\\= 3x^2 - 5xy-6y^2 - 2x^2+3xy-4y^2\\=x^2-10y^2-2xy\\\implies Q(x) - P(x) = (x^2-10y^2-2xy)$

Hence solution to the given expression is $(x^2 -10y^2 -2xy)$
