Prove the following limit. lim x → 5 3x − 8 = 7 SOLUTION 1. Preliminary analysis of the problem (guessing a value for δ). Let ε

Temka [501]

$\displaystyle\lim_{x\to5}3x-8=7$

means to say that for any given $\varepsilon>0$ , we can find $\delta$ such that anytime $|x-5|$ (i.e. the whenever $x$ is "close enough" to 5), we can guarantee that $|(3x-8)-7|$ (i.e. the value of $3x-8$ is "close enough" to the limit value).

What we want to end up with is

$|(3x-8)-7|=|3x-15|=3|x-5|$

Dividing both sides by 3 gives

$|x-5|$

which suggests $\delta=\dfrac\varepsilon3$ is a sufficient threshold.

The proof itself is essentially the reverse of this analysis: Let $\varepsilon>0$ be given. Then if

$|x-5|$

and so the limit is 7. QED

$1689 invested for 4 years at 3% compounded annually ?

Ira Lisetskai [31]

The amount gotten after $1689 invested for 4 years at 3% compounded annually is $1901

The amount of money gained after an investment is compounded is given by:

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

Where P is principal, A is the final amount, r is the rate, n is the number of times compounded per period and t is the time

Given that P = $1689, t = 4, r = 3% = 0.03, n = 1, hence:

$A=P(1+\frac{r}{n} )^{nt}\\\\A=1689(1+\frac{0.03}{1} )^{4*1}\\\\A=\$1901$

The amount gotten after $1689 invested for 4 years at 3% compounded annually is $1901

A linear relationship has a constant rate of change. agree? or disagree? and why?

mestny [16]

Yes, a linear relationship (mathematical) is a constant change happening to x, for example, if in the first step it adds 2 to the table chart or graph, it will always be adding 2 every step of the equason

Taylor used 2 cans of blue paint and 5 cans of yellow paint to decorate a wall. Each can contains 200 millilitres of paint.

rewona [7]

Answer:

Step-by-step explanation:

200 X 5 = 1000

200 X 2 = 200

1000-200= 800.

Taylor uses 800 ml more of yellow paint compared the blue paint.
