Answer:

62.8 square inches

Step-by-step explanation:

we know that

To find out how many square inches of space the rolling pin comes in contact with after one complete roll, determine the lateral area of the rolling pin

The lateral area of a cylinder is given by the formula

LA=\pi Dh

we have

D=2\ in\\h=10\ in\\\pi=3.14

substitute

LA=3.14(2)(10)=62.8\ in^2

Solve 2x2 + 3x = −8.
77julia77 [94]

Answer:

Final answer iis choice B) x=\frac{-3\pm i\sqrt{55}}{4}

Step-by-step explanation:

2x^2 + 3x =-8

2x^2 + 3x +8 = 0

Compare with quadratic equation ax^2 + bx +c = 0, we get:

a=2, b=3, c=8

Now plug these values into quadratic formula:

x=\frac{-3\pm \sqrt{\left(3\right)^2-4\left(2\right)\left(8\right)}}{2\left(2\right)}

x=\frac{-3\pm \sqrt{9-64}}{4}

x=\frac{-3\pm \sqrt{-55}}{4}

x=\frac{-3\pm i\sqrt{55}}{4}

Hence final answer iis choice B) x=\frac{-3\pm i\sqrt{55}}{4}

lions [1.4K]

Answer:

  4424 books

Step-by-step explanation:

After the revenue from each book pays for its own cost, it can contribute to the payment of the fixed costs. That "contribution margin" is ...

  $25.50 -11.25 = $14.25

If each book sold contributes that much to the recovery of fixed costs, then the total number of books that must be sold to break even is ...

  $63,042/($14.25/book) = 4424 books

4424 books must be produced and sold so production costs equal sales.
