The problem says to add, so

3.54 + 5.12 + 2.3 =

10.96 in (your sum/perimeter)

Matt bought a home in 2001 and paid $150,000 for it. He sold the home for $450,000. How much of the profit on his home will be t

butalik [34]

Answer:

profit to be taxable will be $300,000

Step-by-step explanation:

Matt home cost = $150,000

Matt sold his home for = $450,000

so,

cost price will be $150,000

selling price will be $450,000

profit = selling price - cost price

profit = $450,000 - $150,000

profit = $300,000

hence the taxable amount for his home this year will be $300,000

Using a linear approximation, estimate f(2.1), given that f(2) = 5 and f'(x) = √3x-1.

algol [13]

Answer:

$f\left( {2.1} \right) \approx 5.22360$ .

Step-by-step explanation:

The linear approximation is given by the equation

${f\left( x \right) \approx L\left( x \right) }={ f\left( a \right) + f^\prime\left( a \right)\left( {x - a} \right).}$

Linear approximation is a good way to approximate values of $f(x)$ as long as you stay close to the point $x= a$ , but the farther you get from $x=a$ , the worse your approximation.

We know that,

$a=2\\f(2) = 5\\f'(x) = \sqrt{3x-1}$

Next, we need to plug in the known values and calculate the value of $f(2.1)$ :

${L\left( x \right) = f\left( 2 \right) + f^\prime\left( 2 \right)\left( {x - 2} \right) }=5+\sqrt{3(2)-1}(x-2) =5+\sqrt{5}(x-2)$

Then

$f\left( {2.1} \right) \approx 5+\sqrt{5}(2.1-2)\approx5.22360$ .

E^4x-1=3 please help what is the exact solution

Roman55 [17]

combine like terms4ln(x) = 8

divide both sides by 4.ln(x) = 2

exponentiate both sides.eln(x) = e^2

inverse property of exponents and logs x = e^2
