Answer:

$ 4096 on the 7th day

Step-by-step explanation:

From the amount earned for the first 3 days it's 1 , 4 , 16 , .... We realize it increases exponentially.

So therefore:

Day 1 =4⁰

Day 2=4¹

Day 3=4²

Day 4=4³

Day 5=4⁴

Day 6=4⁵

Day 7=4⁶

Therefore on day 7 he saves 4⁶ which is $4096

Use linear approximation, i.e. the tangent line, to approximate √ 16.2 as follows: Let f ( x ) = √ x . Find the equation of the

Dvinal [7]

The linear approximation to $f(x)$ near $x=16$ is

$L(x)=f(16)+f'(16)(x-16)$

We have

$f(x)=\sqrt x\implies f(16)=4$

$f'(x)=\dfrac1{2\sqrt x}\implies f'(16)=\dfrac18$

$\implies L(x)=4+\dfrac18(x-16)=\dfrac x8+2$

Then

$f(16.2)\approx L(16.2)\iff\sqrt{16.2}\approx\dfrac{16.2}8+2$

$\implies\boxed{\sqrt{16.2}\approx4.025=\dfrac{161}{40}}$

Pat invested x dollars in a fund that paid 8% annual interest, compounded annually. Which of the following represents the value,

uysha [10]

Answer: D. $(1.08)^5\times x$

Step-by-step explanation:

The formula to find the compound amount (investment plus interest ) at the end of t years :

$A= (1+r)^t\times P$ (1)

, where r= rate of interest ( in decimal)

P= Initial amount.

As per given , we have

P = x dollars

r = 8% = 0.08

t = 5

Put all the values in (1) , we get

$A= (1+0.08)^5\times x$

$A= (1.08)^5\times x$

Therefore , the the expression that represents the value, in dollars, of Pat's investment plus interest at the end of 5 years :

$(1.08)^5\times x$

Hence, the correct answer is D. $(1.08)^5\times x$
