a pipeline is laid at a rate of 1/8 mile per day.How many miles of line would be completed in 29 1/2 days​
Setler [38]

Answer:

In 29  1/2 days, the total pipe laid is (\frac{59}{16}) mile.

Step-by-step explanation:

The length of pipe laid in 1 day = 1/8 mile

So, the length of pipe laid in half day = half of (1/8 mile)

= \frac{1}{2}  \times \frac{1}{8}  = \frac{1}{16}  \textrm{mile}

Now, 29 1/2 days on simplification means 29 and half day.

So, length of pipe in 29 days = 29 \times \frac{1}{8}  = \frac{29}{8} mile

Now adding the length laid in half day = \frac{29}{8}  + \frac{1}{16}  = \frac{29 (2) + 1}{16}  = \frac{59}{16}  \textrm{mile}

So, in 29  1/2 days, the total pipe laid is (\frac{59}{16}) mile.

What are the vertical and horizontal asymptotes for the function f(x)=<br> 3x2/x2-4
Alecsey [184]

Answer:  f(x) will have vertical asymptotes at x=-2 and x=2 and horizontal asymptote at y=3.

Step-by-step explanation:

Given function: f(x)=\dfrac{3x^2}{x^2-4}

The vertical asymptote occurs for those values of x which make function indeterminate or denominator 0.

i.e. x^2-4=0\Rightarrow\ x^2=4\Rightarrow\ x=\pm2

Hence, f(x) will have vertical asymptotes at x=-2 and x=2.

To find the horizontal asymptote , we can see that the degree of numerator and denominator is same i.e. 2.

So, the graph will horizontal asymptote at y=\dfrac{\text{Coefficient of }x^2\text{ in numerator}}{\text{Coefficient of }x^2\text{ in denominator}}

i.e. y=\dfrac{3}{1}=3

Hence, f(x) will have horizontal asymptote at y=3.

Solve 5kx + 6 = 7kx for x.<br> А. x=3/k<br> в. х = -2/k<br> с. x =-3/k<br> D. x=2/k
slamgirl [31]

Answer:

A.  x = 3/k.

Step-by-step explanation:

5kx + 6 = 7kx

5kx - 5kx + 6 = 7kx - 5kx

6 = 2kx

x = 6 / 2k

x = 3/k.
