Tyler finds an expression for V(x) that gives the volume of an open-top box in cubic inches in terms of the length x in inches o
f the square cutouts used to make it. This is the graph Tyler gets if he allows x to take on any value between -1 and 7.
What is the approximate maximum volume for his box?

Answer:
x = 7.99 cm
Step-by-step explanation:
By applying cosine rule in the given triangle,
AC² = AB² + BC² - 2(AB)(AC)cosC
Substitute the measures of the sides and the angle in this formula,
x² = 6² + 10² - 2(6)(10)cos(53°)
x² = 36 + 100 - 72.217
x² = 63.782
x = √(63.782)
x = 7.99 cm
Answer:
Option C
The student's conclusion is correct because the solution to the system of equations and
is
Step-by-step explanation:
Let
x------> the cost of each burger
y-----> the cost of each sandwich
we know that
-----> equation A
----> equation B
Solve the system of equations
Multiply the equation B by
----->
------> equation C
Adds equation A and equation C
Substitute the value of x in the equation B
The solution of the system of equations is the point
so
The price of each burger is
The price of each sandwich is
