Explanation of Solution
Given:
Height of
Breadth of rectangle=
Length of rectangle=
Formula used:
Area of triangle=
Area of rectangle=
Calculation:
Area of figure= 2(area of triangle)+area of rectangle.
Rectangle,
Substituting values,
Area=
Solving,
Area=
Now,
Area=
Hence area of rectangle=
Triangle,
Here,
2( base ) = length of triangle
So,
Substituting values in formula,
Area=
Solving,
Area=
Now, put values of area in above,
Area of figure=
Solving,
=
Adding terms,
=
Hence, this is the area of the figure.

To find the maximum value of h
b.

Answer to Problem 8.3.2P
Explanation of Solution
Given:
Equation is
Calculation:
To find the maximum value of h,
Put
Multiplying by -1,
Grouping values,
Now taking common,
Taking common again,
For equation to be 0,
Taking
So,
Put value of h in equation.
Maximum area is 55.55 cubic unit

- Café Michigan's manager, Gary Stark, suspects that demand for mocha latte coffees depends on the price being charged. Based on historical observations, Gary has gathered the following data, which show the numbers of these coffees sold over six different price values: Price Number Sold $2.70 765 $3.50 515 $2.00 990 $4.30 240 $3.10 325 $4.00 475 Using simple linear regression and given that the price per cup is $1.85, the forecasted demand for mocha latte coffees will be cups (enter your response rounded to one decimal place).arrow_forwardGiven the correlation coefficient (r-value), determine the strength of the relationship.
