Answer:
45t = distance
Step-by-step explanation:
Distance = speed * time
Distance= 45 mph * t hours = 45t
5. 623. Just split the shape into two. then find the area of two figures that you created. Then add.
6. V = 138.125. Just multiply all the numbers together for this problem.
7. SA = 392. Use the formula <span>2(lw + lh + wh). </span>
An equation for the parabola would be y²=-19x.
Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis. This means we will use the standard form
(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.
Beginning with the directrix:
x=h-p=4.75
h-p=4.75
Since the vertex is at (0, 0), this means h=0 and k=0:
0-p=4.75
-p=4.75
p=-4.75
Substituting this into the standard form as well as our values for h and k we have:
(y-0)²=4(-4.75)(x-0)
y²=-19x
