During covalent bonding, if the nuclei of the two atoms are unequally attractive to the electrons this molecule is said to be…

RNA and DNA are both composed of nucleotides.

Which of the following statements concerning enzymes is TRUE?

Which of the following augmented matrices are in reduced row-echelon form?

Suppose the Going Home Club held a fundraiser so they can… go home. They sold cookies for $2 each and brownies for $4 each. At the end of the day, the club leader tells everyone that they raised $4000, and they sold three times as many cookies as they did brownies. Set up (but do not solve) a system of equations to determine the numbers of cookies (\(c\)) and brownies (\(b\)) sold.

In the summer of 1991, Sega launched a bundle of their Genesis video game console with Sonic the Hedgehog. To aggressively sell it, they lowered the price of the bundle from $190 to $150. Suppose marketing data showed that if the price was $190, they would have only sold 390,000 units that summer. Instead, at the new price, they sold 750,000 units that summer. What is the demand function, \(p(x)\), for the Genesis for that summer, where \(p\) is in dollars and \(x\) is the number of bundles sold?   TO DO: Change to “last week of June 1991” and divide all quantities by 10.

Suppose we have a line described by the equation 10x – 2y = 8. If \(x\) were to decrease by 8 units, what would the corresponding change in \(y\) be?

Multiplying a matrix by a single number will not change the number of rows and columns of the matrix.

The following augmented matrix, in reduced row-echelon form, represents a system of linear equations in two variables, \(x\) and \(y\). This system has [n] solutions.

Suppose \(A\) is a 4×3 matrix and \(B\) is a 3×4 matrix. What are the dimensions of \(29A\) ? If these calculations are not possible, just put DNE in each blank.   Your answer: [r] x [c]
