Answer:  The required zero of the given function is x = -1.4.

Step-by-step explanation:  We are given to find all the real zeroes of the following function :

y=-5x-7~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

Since the given function is linear, so it will have only one real zero.

Also, the zeroes of a function y = f(x) is given by f(x) = 0.

So, the zero of the given function (i) is

y=0\\\\\Rightarrow -5x-7=0\\\\\Rightarrow 5x=-7\\\\\Rightarrow x=-\dfrac{7}{5}\\\\\Rightarrow x=-1.4.

Thus, the required zero of the given function is x = -1.4.

Find the distance between the points (5, -5) and (-7,4).
abruzzese [7]

Answer:

<h2>The answer is 15 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(5, -5) and (-7,4)

The distance between them is

d =  \sqrt{ ({5 + 7})^{2}  +  ({ - 5 - 4})^{2} }  \\  =  \sqrt{ {12}^{2}  + ( { - 9})^{2} }  \\  =  \sqrt{144 + 81}  \\  =  \sqrt{225}  \\  = 15 \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>15 units</h3>

At total of 2 feet of snow falls over three days on the first day 1/6 of the snow falls on the second day 7/12 of the snow falls
ioda

Answer:

Day\ 3 = 1\frac{3}{12}

Step-by-step explanation:

Given

Total = 2ft

Day\ 1 = \frac{1}{6}

Day\ 2 = \frac{7}{12}

Required

Determine the amount of snow on day 3

This can be calculated using:

Day\ 1 + Day\ 2 + Day\ 3 = Total

Substitute values for the known parameters

\frac{1}{6} + \frac{7}{12} + Day\ 3 = 2

Collect Like Terms

Day\ 3 = 2 - \frac{1}{6} - \frac{7}{12}

Take LCM

Day\ 3 = \frac{24 - 2 - 7}{12}

Day\ 3 = \frac{15}{12}

Express as mixed number

Day\ 3 = 1\frac{3}{12}
