Write in vertex form the quadratic that has a vertex of (3,4)

a = 1

h = ?
k = ?

Step-by-step explanation:

By definition, we know that the quadratic equation in the vertex form is:

Where (h, k) is the vertex.

We have the vertice. (3, 4)

Then, if the vertex is (3,4), the equation sought is the following:

Therefore the answer is:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
