svetoff [14.1K]

Answer: Peters average speed in m/min is 294.1176 m/min


Step-by-step explanation:


Peter participated in a 5000m race and finished the race in 17 min.


Speed is calculated as Distance/Time


Peters average speed in m/min = Distance covered in m / Time taken in minutes

= 5000/17

= 294.1176 m/min


Therefore, Peters average speed in m/min = 294.1176 m/min


Hope it helps.


Thank you :)

Please Helpppppp!!!!! What is the value of x.
timama [110]

Answer:

Step-by-step explanation:

Remark

By corresponding angles and vertical angles, these two angles are equal.

Equation

-1 + 14x = 12x + 17                      Subtract 12x   from both sides

Solution

-1 + 14x - 12x = 12x - 12x + 17

-1 + 2x = 17                                 Add 1 to both sides

-1+1 + 2x = 17 + 1

2x = 18                                       Divide by 2

2x/2 = 18/2

x = 9

Determine f^-1(2) given the following: f(1 = -3f(2) = -2f(-1) = 2f(3) = -1
lana [24]

We assume that the function is as follows:

f^{-1_{}}(2)=?

Then, we have that:

f^{-1}(x)=\frac{1}{f(x)}

Thus, if we have that:

f(2)=-2\Rightarrow f^{-1^{}_{}}(x)=\frac{1}{f(x)}\Rightarrow f^{-1}(2)=\frac{1}{f(2)}=\frac{1}{-2}\Rightarrow f^{-1}(2)=-\frac{1}{2}

Therefore, the value for the function is f^-1(2) = -1/2 or

f^{-1}(2)=-\frac{1}{2}
