BaLLatris [955]
40 mph would be 120 miles in 3 hours (120/40)

80 mph is 120 miles in 1.5 hours(120/80)

3 - 1.5 = 1.5, not 3 hrs

Change the speed to 20 mph( 1/2 the speed) to double the hours.

20 mph = 6 hours(120/20)

40 mph = 3 hrs(120/40)

6 - 3 = 3 hours difference

Jessica is a custodian at Oracle Arena. She waxes 20 \text{ m}^220 m 2 20, space, m, start superscript, 2, end superscript of th
Evgesh-ka [11]

Given that Jessica is a custodian at Oracle Arena.

She waxes 20 square meters space of the floor in 5/3 of an hour. Jessica waxes the floor at a constant rate means rate will remain fixed for any hour.

Now we have to find about how many square meters can she wax per hour.

To find that we just need to divide 20 squaer meters by 5/3 hours

\frac{20}{\left(\frac{5}{3}\right)}

=20\cdot\frac{3}{5}

=\frac{60}{5}

=12

Hence final answer is 12 square meters can she wax per hour.

Which can also be written as 12m^2 per hour.

The standard form of a parabole is: (y-k) = a(x-h)², Where (h , k) are the coordinates of the vertex
In the example Vertex (3,1) ,
so (y-1) = a(x-3)². (a)
Now let's calculate a. The y-intercept coordinates(0 , 10), Replace in (a) x by 0 & y by 10:
(10-1) = a(0 - 3)²
9 = 9a and a=1
<u />The equation becomes : y-1 = (x-3)², Expand (y-1) = x²-6x+9
<u />and finally y = x² - 6x +10 (ANSWER C)
