Answer:
Step-by-step explanation:
Let
Side of square base=x
Height of rectangular box=y
Area of square base=Area of top=
Area of one side face=
Cost of bottom=$9 per square ft
Cost of top=$5 square ft
Cost of sides=$4 per square ft
Total cost=$204
Volume of rectangular box=
Total cost=
Substitute the values of y
Differentiate w.r.t x
It takes positive because side length cannot be negative.
Again differentiate w.r. t x
Substitute the value
Hence, the volume of box is maximum at x=2.2 ft
Substitute the value of x
Greatest volume of box=
Approximately 21.22 yards.
Answer:
x = 17°
Step-by-step explanation:
<u>Angles And Parallel Lines
</u>
If two parallel lines are crossed by a third line, corresponding angles are congruent. Also, consecutive angles are supplementary
We can clearly see in the image provided, being w and b parallel, that the corresponding angles (4x-3) and 65° are congruent. We can express that relation as
Operating
So the value of the angle x is 17°
It is within 5 minutes ahead or behind 5 minutes of 64 minutes because deviantion means a different face value than the original hope this helps
