This is a parabola which looks like an inverted U. Its will have a maximum value when t = 7 as we see from the vertex form below:-
- t^2 + 14t - 40
= - ( t - 7)^2 + 49 - 40
= -(t - 7)^2 + 9
There is an axis of symmetry at x = 7.
so a is true since 7 is the maximum value of the function and its less at t = 6.
c is also true because of the symmetry about t = 7
It helps demonstrate it since it forms a right triangle in the middle with 2 base lengths and a hypotenuse. The areas of the squares can be plugged into the pythagorean theorem in order to find the answer
6x^2/2x^2

The amount that Tony and his friend's will spend at the dell can be found by
writing an expression for the total cost.
<h3 /><h3>Response;</h3>
- The amount that they spent at the dell is <u>$16</u>
<h3 /><h3>Method used in finding the amount that was spent;</h3><h3>Given;</h3>
The number of Toby's friends = 3
Number of people that ate lunch, n = Toby + His friends = 1 + 3 = 4
The cost of the sandwiches and drinks
![\begin{tabular}{|c|c|c}Item&Cost(\$)\\Sandwich&2.75\\Drink &1.25\end{array}\right]](https://tex.z-dn.net/?f=%5Cbegin%7Btabular%7D%7B%7Cc%7Cc%7Cc%7DItem%26Cost%28%5C%24%29%5C%5CSandwich%262.75%5C%5CDrink%20%261.25%5Cend%7Barray%7D%5Cright%5D)
<h3>Solution;</h3>
The expression that gives the amount Toby and his friends spend altogether is therefore;
Amount spent = n × (Cost of a sandwich + cost of a drink)
Which gives;
4 × (2.75 + 1.25) = 16
- The amount Tony and his friends spent is<u> $16</u>.

Unfortunately, your answer is incorrect, but I totally understand your thinking. However, 1/4 is the probability for each individual that they'll be placed in a general civil case. Since there are two of them, and the question is asking the probability that only one will be in a general civil case, you have to approach the problem slightly differently.
There is a 1/16 chance that both will be put in the case (1/4 * 1/4), a 9/16 chance that neither will be put in the case (3/4 * 3/4), and therefore leaving a 6/16 chance that only one of them will be placed in the civil case. (1 - (1/16 + 9/16). This is equivalent to the decimal 0.375.
Draw out a chart of all the 16 possibilities, and circle the ones where the criteria meet. You'll find that there are 6 instances where one of them is put in a general civil case alone.
