Answers

Answer:

f(x) = -(x-3)^2 + 4

Step-by-step explanation:

(h; k) are the coordinates of the vertex.

On the graph are (3, 4), therefore we have:

f(x) = a(x-3)^2 + 4

We have the x- intercept (1,0) -> x=1; y=0.

Substitute them into the equation:

0 = a(1 - 3)^2 + 4

0 = a(-2)^2 + 4

4a + 4 = 0 | -4

4a = -4   |-4

a = -1

So, we have the answer:

f(x) = -(x-3)^2 + 4

y-4/9=5 1/3
pls step by step

Answers

Answer:

y = 5 7/9

Step-by-step explanation:

To get y in it's own, first add 4/9 + 5 1/3 or 4/9 + 16/3. To solve this, find the common denominator (9): 4/9 + 48/9. Add to get: 52/9. Now switch to a mixed number: 5 7/9. This can't be simplified any further, so our new equation is:

y = 5 7/9

If d represents the distance that the plane flies at this speed for t hours, write an equation that relates t and d.

Answers

Answer:

d = rt

Step-by-step explanation:

D = Distance

An equation that relates t and d is

Given :

If d represents the distance that the plane flies at this speed for t hours

To write the equation that relates t  and d

We know that distance is equal to speed times time taken

'd' is the distance

't' is the time taken

[tex]Distance = speed \cdot time \\speed =\frac{distance }{time }[/tex]

Lets replace the variables for distance and time

d represents the distance and 't' represents the time in hours
