Answer:
3) 
Step-by-step explanation:
The equation of a circumference is 2

r. Since we know that r=17, we plug that into the formula, and get an answer of C. 34
Answer:
The x-coordinate of another point is zero
Step-by-step explanation:
step 1
Find the slope between the two given points
The formula to calculate the slope between two points is equal to
we have
substitute in the formula
Simplify
step 2
Find the x-coordinate of another point
we have
(x,-3)
we know that
If the other point is on the line, then the slope between the other point and any of the other two points must be the same
so
Find the slope between the points
Remember that
substitute in the formula
the denominators must be the same


therefore
The x-coordinate of another point is zero
Answer:
The speed of the cars is 
Step-by-step explanation:
First we must first have the clear concept that
or 
Our question is the speed of the cars then the variable to clear will be s.
Let's raise the equation for each car taking into account that we have the following data:
Car 1:
,
and 
Car 1:
,
and 
The two cars travel the same distance so we will raise the distance formula for each car and then match them.
<em>Car 1</em>



<em>Car 2</em>







The speed of the cars is 32 km/hr
