Answer:
.3 repeating
Step-by-step explanation:
Answer:
V ≈ 143.91938 ft
Step-by-step explanation:
V = π r² h
V = π r² h = π · 49² · 180
V ≈ 1.35773 × 10⁶
V ≈ 143.91938 ft
<em><u>Solution:</u></em>
Given that we have to find the vertex
<u><em>The vertex form of equation is written as:</em></u>
Where, (h, k) is the vertex
Given equation is:
Convert to vertex form
The above equation is of vertex form
On comparing vertex form with above equation,
On comparing we get,
h = 0
k = -2
Thus vertex is (h, k) = (0, -2)

Step-by-step explanation:
Distance = Speed * Time
If Maria drove to a business appointment at 30 mph, then
d = 30t where d is her distance and t is the time
If her average speed on the return trip in the afternoon was 20 mph and the return trip took 1/2 hr longer, then;
her speed s = 20mph
her time t1 = 1/2 + t
distance d = 20(1/2+t)
Since the distance both going and returnin are the same then:
30t = 20(1/2 + t)
3/2 t = 1/2 + t
3/2 t - t = 1/2
1/2 t = 1/2
t = 1 hr
Substitute t = 1hr into the first equation to get the distance
d = 30t
d = 30(1)
d = 30miles
Hence she travelled 30 miles to the appointment
