Answer:

y=4/3x-2

Step-by-step explanation:

We know the base equation is mx+b and the y-intercept is at -2 so we can determine that as the b value. The m value is 4/3 because if you look at where the line meets the next point is over 3 and up 4 indicating that the m value is 4/3. Hope this helps!

The equation of the line is y = 4/3x -2.

The y-intercept is -2 because the line crosses the y-axis at (0,-2).

The slope is 4/3x because the rise over run of the line is 4/3.

What is the value of log0.5 16 (0.5 is the small bottom number)<br>-4.00<br>-0.25<br>1.51<br>2.41

eduard

we are given

$log_0_._5(16)$

Firstly, we will factor out 16

$16=2\times 2\times 2\times 2\times 2$

$16=2^4$

we can write it as

$16=(\frac{1}{2})^{-4}=(0.5)^{-4}$

we can replace it as

$log_0_._5(16)=log_0_._5((\frac{1}{2})^{-4})$

now, we can use property of log

$log_a(b^n)=nlog_a(b)$

we get

$log_0_._5(16)=-4log_0_._5(0.5)$

$log_0_._5(16)=-4\times 1$

$log_0_._5(16)=-4$ .............Answer

Answer:

a) 13913

b) 4913.82

Step-by-step explanation:

The compound interest formula is given by:

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

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

In this question:

Investment of 9000, so $P = 9000$
