PEMDAS

The PEMDAS rule is an acronym representing the order of operations in math:

Parentheses
Exponents
Multiplication and Division (from left to right)
Addition and Subtraction (from left to right)

Solution Option 1

(Taking * as a multiplication sign)

Given equation:

4(2 × 2 + 3) - 2 × 2 = -(3 × 2 - 1) + 29

Following the order of operations, carry out the operations inside the parentheses first, starting with the multiplication:

4(4 + 3) - 2 × 2 = -(6 - 1) + 29

Carry out the addition and subtraction inside the parentheses:

4(7) - 2 × 2 = -(5) + 29

Now carry out the multiplication:

28 - 4 = -5 + 29

Finally carry out the addition and subtraction:

24 = 24

Solution Option 2

(Taking * as a "raising to the power of" sign)

Given equation:

4(2² + 3) - 2² = -(3² - 1) + 29

Following the order of operations, carry out the operations inside the parentheses first, starting with the exponents:

4(4 + 3) - 2² = -(6 - 1) + 29

Carry out the addition and subtraction inside the parentheses:

4(7) - 2² = -(5) + 29

Now carry out the exponents:

28 - 4 = -5 + 29

Finally carry out the addition and subtraction:

24 = 24

What are the approximate values of the minimum and maximum points of f(x) = x5 − 10x3 + 9x on [-3,3]? A. maximum point: (–2.4, 3

slava [35]

Answer:

(-2.4, 37.014)

Step-by-step explanation:

We are not told how to approach this problem.

One way would be to graph f(x) = x^5 − 10x^3 + 9x on [-3,3] and then to estimate the max and min of this function on this interval visually. A good graph done on a graphing calculator would be sufficient info for this estimation. My graph, on my TI83 calculator, shows that the relative minimum value of f(x) on this interval is between x=2 and x=3 and is approx. -37; the relative maximum value is between x= -3 and x = -2 and is approx. +37.

Thus, we choose Answer A as closest approx. values of the min and max points on [-3,3]. In Answer A, the max is at (-2.4, 37.014) and the min at (2.4, -37.014.

Optional: Another approach would be to use calculus: we'd differentiate f(x) = x^5 − 10x^3 + 9x, set the resulting derivative = to 0 and solve the resulting equation for x. There would be four x-values, which we'd call "critical values."

Paha777 [63]

Answer:

S(-8,-3), T(0, -3), and U(-7, -8)

Step-by-step explanation:

for all of the coordinates, you would subtract 8 from their X-values, and subtract 13 from their Y-values.
