The <em><u>correct answers</u></em> are:

3/2 - expansion; 1/4 - contraction; 4 - expansion; 0.8 - contraction; -3 - expansion.

Explanation:

A scale factor larger than 1 would be an expansion. The factors we have listed that are larger than 1 are 3/2 and 4.

A scale factor between 0 and 1 would be a contraction. The factors we have listed that are between 0 and 1 are 0.8 and 1/4.

A negative scale factor will result in a larger, inverted figure. This means the scale factor of -3 will be an expansion.

Contractions are dilations less than 1 but more than 0, and Expansions are dilations more than 1.

3/2 : Expansion
1/4 : Contraction
4 : Expansion
0.8 : Contraction
-3 : Expansion

These should be the right answers.

Solve the following maximization problem graphically.

rjkz [21]

The maximized value of the function is (c) 119/2

<h3>Maximization problem</h3>

Maximization problems are used to determine the optimal solution of a linear programming model

<h3>Objective function</h3>

The objective function is given as:

$P(x,y) = 11x + 10y$

<h3>Constraints</h3>

The constraints are given as:

$22x + 2y \le 68$

$8x + 16y \le 68$

$x,y\ge 0$

<h3>Graph</h3>

See attachment for the graph of the constraints

From the graph, the optimal solution is: (2.83, 2.83)

So, the maximized value is:

$P(x,y) = 11x + 10y$

$P =11 \times 2.833 + 10 \times 2.833$

$P =59.493$

Approximate

$P =59.5$

Rewrite as a fraction

$P =\frac{119}{2}$

Hence, the maximized value of the function is (c) 119/2

What is the perimeter of quadrilateral ABCD?

Bogdan [553]

Answer:

I believe it is 18 + the square root of 26.

Step-by-step explanation:

The slope of line BC should be 5/1 because it goes up 5 times and to the right once. If you square root 26 you get 5.09.

Which is bigger 5/8 or 0.58

Luden [163]

Hello!

To compare the two, we must convert 5/8 to a decimal. We'll do that buy dividing the numerator by the denominator.

5 ÷ 8 = 0.625

Compare the two decimals.

0.625 vs. 0.580

So, 5/8 is obviously bigger than 0.58.
