First isolate y for each equation so that y = x^2 + 3 and y = 2x^2 + 2 now set those equal to eachother and solve for x, 

x^2 + 3 = 2x^2 + 2
= √x^2 = <span>√1
x is +- 1

then plug in x for one of the original equations y = 1^2 + 3 = 4

x = +-1
y = 4</span>

Answer:

The function that best models the given data is;

B. h(t) = -6.73·t² + 14.19·t + 0.83

Step-by-step explanation:

The data in the given table is presented as follows

\begin{array}{cccccc}Time, \, t(s)&0&0.5& 1.0 & 1.5& 2.0\\Height, \, h \, (m) & 1.0 & 5.42 & 9.71 & 5.9 & 2.6\end{array}

Where;

Time, t(s) is the independent variable

Height, h(m) is the dependent variable

Therefore, we have;

When t = 0, h = 1.0

From the given functions, we have the following table of the result of the function generated with Microsoft Excel

\begin{array}{cccccc}\\t & h & A & B & C& D\\0 & 1.0 & 1.22 & 0.83& 0.83& 1.22\\0.5 & 5.42 & 5.26 & 6.2425 & 9.6075 & 10.17\\1 & 9.71 &  4.39 & 8.79 & 21.75 & 24.03 \\ 1.5 & 5.9 &  -1.39& 6.9725& 37.2575 &42.8\\2& 2.6 & -12.08 & 2.29 & 56.13 & 66.48\end{array}

By comparison, the function that nest models the given data is the function 'B', given as follows;

h(t) = -6.73·t² + 14.19·t + 0.83.

alina1380 [7]

Answer:

23.5 miles a gallon, and $18.90 trip cost.

Step-by-step explanation:

16 is the full tank, and 6 is 3/8ths of that, so 6 gallons were used during the trip.

Miles per gallon:

141/6 = 23.5

The fuel mileage was <em>23.5</em> miles a gallon.

Cost:

6 * 3.15 = 18.9

The cost of the trip was <em>$18.90.</em>
