<h3>Answer:</h3>

17. 2x^4 + x^3 + x^2 + 4x + 3 + 8/(x -1)

18. x = 2, x = -2

19. The slant asymptote is y = x + 14

<h3>Explanation:</h3>

17. See the first attachment for the synthetic division. The summary statement is the expression represented by the result.

18. The denominator is the difference of two squares, so is readily factored to ...

... (x -2)(x +2)

The zeros of this product are the locations of the vertical asymptotes of f(x). They are ...

... x = 2, x = -2.

19. Dividing the numerator by the denominator (using synthetic division, if you like) gives the result ...

... f(x) = x + 14 + 104/(x -8)

The linear expression y=x+14 defines the end behavior when x gets large. That is, it is the slant asymptote of the function. See the second attachment for a graph.

(There will be a horizontal asymptote only when the degrees of numerator and denominator are the same. In this case, they are not.)

Elena-2011 [213]

Answer:

5 years

Step-by-step explanation:

In the question we are given;

Amount invested or principal amount as $5048
Rate of interest as 4% compounded 12 times per year
Amount accrued as $6,163.59

We are required to determine the time taken for the money invested to accrue to the given amount;

Using compound interest formula;

$A=P(1+\frac{r}{100})^n$

where n is the interest period and r is the rate of interest, in this case, 4/12%(0.33%)

Therefore;

$6,163.59=5,048(1+\frac{0.333}{100})^n$

$1.221=(1+\frac{0.333}{100})^n$

$1.221=(1.0033)^n$

introducing logarithms on both sides;

$log1.221=log(1.0033)^n\\n=\frac{log1.221}{log1.0033} \\n=60.61$

But, 1 year = 12 interest periods

Therefore;

Number of years = 60.61 ÷ 12

= 5.0508

= 5 years

Therefore, it will take 5 years for the invested amount to accrue to $6163.59

1. Some roads in Poland have a speed limit of 140 km/h. How fast is this in miles per minute?

Y_Kistochka [10]

I only know number one here you goSolution
Conversion for Km to Miles
1km = 0.621 miles

Conversion Hours to minutes
1 hr = 60 mins

solve
140 (0.621 miles / 60 mins )
= 140 (0.01035 miles/min)
= 1.449 miles/min
