Explanation Obtain the product of 2 A . Each entry of the matrix A multiplied by a scalar 2. 2 A = 2 [ 1 0 24 6 ] = [ 1 ( 2 ) 0 ( 2 ) 24 ( 2 ) 6 ( 2 ) ] = [ 2 0 48 12 ] That is, 2 A = [ 2 0 48 12 ] (1) Obtain the product of 3 B . Each entry of the matrix B multiplied by a scalar 3. 3 B = 3 [ 22 2 5 3 ] = [ 22 ( 3 ) 2 ( 3 ) 5 ( 3 ) 3 ( 3 )

Algebraic Expressions

In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.

Numbers

Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.

Subtraction

Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.

Use a calculator to find a decimal approximation for the following trigonometric function. cot 226°54' cot 226°54' (Simplify your answer. Type an integer or a decimal. Round to eight decimal places as needed.)

In preparing for the upcoming holiday season, Fresh Toy Company (FTC) designed a new doll called The Dougie that teaches children how to dance. The fixed cost to produce the doll is $100,000. The variable cost, which includes material, labor, and shipping costs, is $31 per doll. During the holiday selling season, FTC will sell the dolls for $39 each. If FTC overproduces the dolls, the excess dolls will be sold in January through a distributor who has agreed to pay FTC $10 per doll. Demand for new toys during the holiday selling season is extremely uncertain. Forecasts are for expected sales of 60,000 dolls with a standard deviation of 15,000. The normal probability distribution is assumed to be a good description of the demand. FTC has tentatively decided to produce 60,000 units (the same as average demand), but it wants to conduct an analysis regarding this production quantity before finalizing the decision. (a) Determine the equation for computing FTC's profit for given values of the…
