Answer:

Step-by-step explanation:
Notice that the focus is a points on the vertical axis, that means the parabolla opens vertically, and has the form

Because the parameter
is positive and equal to 0.75. Additionally, the vertex is at the origin, that's why the equation is this simple.
Replacing the parameter value, we have

Therefore, the equation of a parabolla with vertex at the origin and focus at (0, 0.75) is
.
11 3/8 would be the simplified version and 91/8 would be the other way.
Average speed = Total distance/Time
A = 550km/6.5hr
A = 84.6 km per hr
Answer:
40.56
Step-by-step explanation:
you need the circumference of the cirle aka perimeter of circle so 8(pi) and then because its only half, divided by 2... 12.56
now you hgave circumference so add 12.56 to 28 and there you go. you can round how ever necessary
Hello!
<em><u>Answer:</u></em>
<em><u>p<6</u></em>
<em><u>*The answer must have a positive sign and less than symbol sign.</u></em>
Step-by-step explanation:
First, you subtract by 7 from both sides of an equation.

Then, simplify.

Next, multiply by -1 from both sides of an equation.

Simplify.

You can also divide by 2 from both sides of an equation.

And finally, simplify and solve. You can also divide by the numbers.

Final answer: 
Hope this helps!
Thanks!
