Tyrone has $500 in his savings account. He wants to save more money. He is looking at two investment plans. Under plan A, he wil

Marrrta [24]

Answer:

$\$522.78$

Step-by-step explanation:

Let

x ---> the number of years

y ---> the amount in the account balance

Plan A

we have a linear equation of the form

$y=mx+b$

where

The slope is equal to

$m=\$100\ per\ year$

The y-intercept or initial value is

$b=\$500$

substitute

$y=100x+500$

For x=10 years

substitute

$y=100(10)+500=\$1,500$

Plan B

we have a exponential growth function of the form

$y=a(1+r)^x$

where

$a=\$500\\r=15\%=15/100=0.15$

substitute

$y=500(1+0.15)^x$

$y=500(1.15)^x$

For x=10 years

substitute

$y=500(1.15)^{10}=\$2,022.78$

Find the difference of the two account balances after 10 years

$\$2,022.78-\$1,500=\$522.78$

Find the value of a and b if root3-1/root3+1+ root3+1/root3-1=a+root3 b

Digiron [165]

Answer:

a=4 and b = 0

Step-by-step explanation:

Given : $\dfrac{\sqrt 3 -1}{\sqrt 3+1}+\dfrac{\sqrt 3+1}{\sqrt 3-1}=a+\sqrt 3 b$

To find, The value of a and b

Solution,

Solving LHS of the given equation,

$\dfrac{(\sqrt 3-1)^2+(\sqrt3+1)^2}{(\sqrt 3+1)(\sqrt 3-1)}=a+\sqrt 3 b$

Since,

$(a-b)^2=a^2+b^2-2ab\\\\(a+b)^2=a^2+b^2+2ab\\\\(a-b)(a+b)=a^2+b^2$

So,

$\dfrac{3+1-2\sqrt 3+3+1+2\sqrt 3}{3-1}=a+\sqrt 3 b\\\\4=a+\sqrt 3 b$

$4+0=a+\sqrt 3 b$

On comparing we get :

a = 4 and b = 0
