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
.
Answer:
3 multiply by 6 multiply by 5
= 90 cm²
Answer:
The answer is t=8
Step-by-step explanation:
simplify both sides or the equation, then isolate the variables
This would be displayed as
3x/5
