To find the total increase, we will subtract -14 from 36.
36--14=50
(A double negative is a positive.)

The range of the function is \{-19,-4,16\}

Explanation:

The function is f(n)=5n-4

The domain of the function is \{-3,0,4\}

We need to find the range of the function.

The range can be determined by substituting the values of domain in the function.

Thus, the range of the function when the domain is -3 is given by

f(-3)=5(-3)-4

         =-15-4

         =-19

Thus, the range is -19 when n=-3

The range of the function when the domain is 0 is given by

f(0)=5(0)-4

       =0-4

       =-4

Thus, the range is -4 when n=0

The range of the function when the domain is 4 is given by

f(4)=5(4)-4

       =20-4

       =16

Thus, the range is 16 when n=4

Thus, the range of the function is \{-19,-4,16\} when their corresponding domain is \{-3,0,4\}

Arranging the range in order from least to greatest is given by

\{-19,-4,16\}

Hence, the range of the function is \{-19,-4,16\}

In the figure, two poles are 25 m and 35 m high. A cable 23 m long Joins the tops of the poles. Find the distance between the po
sukhopar [10]

Answer: 20.71 m

Step-by-step explanation:

Given

the length of the poles are 25m and 35 m

The length of the cable is 23 m

Suppose the distance between them is x

From the figure, apply Pythagoras theorem

\Rightarrow 23^=x^2+10^2\\\Rightarrow 529-100=x^2\\\Rightarrow x^2=429\\\\\Rightarrow x=\sqrt{429}=20.71\ m

Distance between Poles is 20.71 m

Archy [21]
<span>2x-3y=18 
when x = 3
2(3) - 3y = 18
6 - 3y = 18
-3y = 12
   y = -4

so(3, -4) is the solution
