Answer:

1) Volume of prism = $\frac{105}{8}ft^3=13.125ft^3$

2) Option B is the correct answer.

Explanation:

1) Volume of a prism is given by the expression, Volume V = Base area of prism x Height of prism.

Base area = $3\frac{1}{2} *2\frac{1}{2}=\frac{3*2+1}{2} *\frac{2*2+1}{2} =\frac{7}{2} *\frac{5}{2}=\frac{35}{4} ft^2$

Volume = $\frac{35}{4}*1\frac{1}{2} =\frac{35}{4}*\frac{1*2+1}{2}=\frac{35}{4}*\frac{3}{2}=\frac{105}{8}ft^3$

Volume of prism = $\frac{105}{8}ft^3=13.125ft^3$

2) Volume of a prism is given by the expression, Volume V = Base area of prism x Height of prism.

Base area = $4\frac{1}{4} *3in^2$

Volume = $4\frac{1}{4} *3*1\frac{1}{4}in^3$

Option B is the correct answer.

Answer:

Equation of the parabola: y = 3 - 7x^2

Step-by-step explanation:

The equation of the parabola with vertex (h,k) is y = a(x - h)^2 + k

Thus, the equation of this parabola is y = ax^2+3

To find a, use the fact that the parabola passes through the point (1,−4):

-4 = a(1)^2 +3

Solving this equation, we get that a = −7.

Thus, the equation of the parabola is y = 3 − 7x^2.

It costs a publishing company $0.55 to print one copy of a certain novel. This company paid $725,000 for the rights to the novel

Dmitrij [34]

Answer:

The correct answer is b. 116,900

The publishing company must sell 116,900 copies of the book to break even.

Step-by-step explanation:

Each book costs 0.55 to make and the company can sell it at 6.75, which means that the company earns 6.20 from each book, this is called the net value. If you divide the amount htat the company paid for the rights by the net value you can find the total number of copies that the company has to sell to break even.

# books = $725,000/$6.20 = 116935 or approximately 116900 copies of the book.
