Can someone explain to me how to do this question? It needs to be simplified and no decimals or fractions.

Masteriza [31]

$\sqrt{180} - \sqrt{45 } \\ = \sqrt{2 \times 2 \times 3 \times 3 \times 5} - \sqrt{3 \times 3 \times 5 } \\$

Taking common

$\sqrt{3 \times 3 \times 5} ( \sqrt{4} - 1) \\ = 3 \sqrt{5} (2 - 1) \\ = 3 \sqrt{5}$

Hope it helps mate

For the following amount at the given interest rate compounded continuously, find (a) the future value after 9 years, (b) the

Stella [2.4K]

Answer:

(a) The future value after 9 years is $7142.49.

(b) The effective rate is $r_E=4.759 \:{\%}$ .

(c) The time to reach $13,000 is 21.88 years.

Step-by-step explanation:

The definition of Continuous Compounding is

If a deposit of $P$ dollars is invested at a rate of interest $r$ compounded continuously for $t$ years, the compound amount is

$A=Pe^{rt}$

(a) From the information given

$P=4700$

$r=4.65\%=\frac{4.65}{100} =0.0465$

$t=9 \:years$

Applying the above formula we get that

$A=4700e^{0.0465\cdot 9}\\A=7142.49$

The future value after 9 years is $7142.49.

(b) The effective rate is given by

$r_E=e^r-1$

Therefore,

$r_E=e^{0.0465}-1=0.04759\\r_E=4.759 \:{\%}$

(c) To find the time to reach $13,000, we must solve the equation

$13000=4700e^{0.0465\cdot t}$

$4700e^{0.0465t}=13000\\\\\frac{4700e^{0.0465t}}{4700}=\frac{13000}{4700}\\\\e^{0.0465t}=\frac{130}{47}\\\\\ln \left(e^{0.0465t}\right)=\ln \left(\frac{130}{47}\right)\\\\0.0465t\ln \left(e\right)=\ln \left(\frac{130}{47}\right)\\\\0.0465t=\ln \left(\frac{130}{47}\right)\\\\t=\frac{\ln \left(\frac{130}{47}\right)}{0.0465}\approx21.88$

The solution of the system of equations Ax+y=5 and Ax+By=20 is (2,-3). What are the values of A and B

STatiana [176]

Answer:

A = 4
B = -4

Step-by-step explanation:

Put the values of x and y in the equations and solve the resulting system.

A(2) +(-3) = 5

A(2) +B(-3) = 20

__

The first equation tells the value of A:

2A = 8 . . . . add 3

A = 4 . . . . . .divide by 2

This and the second equation tells the value of B:

(4)(2) -3B = 20

-3B = 12 . . . . . subtract 8

B = -4 . . . . . . . divide by -3

The values of A and B are 4 and -4, respectively.
