Answer:
Step-by-step explanation:
From the question we are told that:
Function given
Co-ordinates
(x,y)=[1, 4]
Generally the second differentiation of function is mathematically given by
Therefore critical point
Generally the substitutions of co-ordinate into function is mathematically given by
For 1
For 4
For critical point 3
Therefore the maximum value of f(x) = –x2 + 6x over the interval [1, 4] is given by
Answer:
2.8 cm
Step-by-step explanation:
The area of a trapezoid is calculated using the formula:
where
B is the length of the major base
b is the length of the minor base
h is the height of the trapezoid
In this problem, the glass window has the shape of a trapezoid. We know that:
B = 2 cm is the length of the top base
b = 4.5 cm is the length of the bottom base
is the area of the trapezoid
Solving for h, we can find the height of the stained glass window:
