Answer:
The equation that can be used to solve for a is 1 = a(0=1)²-3.
Explanation:
In this case, I would model the parabola in vertex form. Vertex form is y = a(x-h)²+k, where (h,k) is the vertex of the parabola. Using the information from the question, we can plug in values to get 1 = a(0+1)²-3. (This could be simplified as 1 = a(1)²-3 ⇒ 1 = a-3 ⇒ a = 4, but we are only interested in finding the equation that can solve for a.)

Step-by-step explanation:
I think this is just a simple addition problem to calculate the exact distance in kilometers.
So add 3.6+4.705+5.92=
14.225 kilometers that Andrea ran over the three days.
Hope this helps, have a good day. c;
Answer:
mean = 172.72cm and variance = 645.16
Step-by-step explanation:
1 inch = 2.54 centimetres
mean = 68 * 2.54 = 172.72 cm
standard deviation = 10 *2.54 = 25.4 cm
variance = square of standard deviation
variance = 25.4 * 25.4
variance = 645.16 cm
