The answer is c i hope this help you out.
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
Answer:
13.2
Step-by-step explanation:
1 liter is equal to 0.264172
0.264172 * 50 = 13.2086

Answer:
Monica has 3 more pieces of gold than silver after she cut all her wire
Step-by-step explanation:
Total length of gold wire Monica has= 7.68 meters
Length of each piece Monica wants to cut the wire into = 0.96 meters
Total number of pieces she can cut =
= 8 pieces of gold wire
Total length of gold wire Monica has = 7.45 meters
Length of each piece Monica wants to cut the wire into = 1.49 meters
Total number of pieces she can cut =
=5 pieces silver wire
Gold wire pieces= 8
Silver wire pieces= 5
Difference in the number of pieces = 
Monica has 3 more pieces of gold than silver after she cut all her wire
