Answer:

For #9, the part of the expression that represents the quotient is the division problem in parenthesis. Specifically, "(45 ÷ 9)". I believe you only need the division symbol for this, though. Correct me if I'm wrong.

As for #10, the part of the expression representing the product of two factors is 5.2 being multiplied by the variable $u$ . This results in the the term $5.2u$ , with the coefficient being 5.2 and the variable being $u$ .

Given the function f ( x ) = − 1 x + 3 x 4 , f(x)=− x 1 + 4 3 x , find f ′ ( 4 ) . f ′ (4). Express your answer as a single fraction in simplest form.

Answers

Step-by-step explanation:

The question is not well written. Let us say the function given as expressed as;

f(x) = -1/x + 3/x⁴

f'(x) means we are to differentiate the function with respect to x;

Given f(x) = axⁿ

f'(x) = naxⁿ⁻¹

f(x) = -x⁻¹ + 3x⁻⁴

Applying the differentiation formula we will have;

f'(x) = -1(-x⁻²)+(-4)3x⁻⁴⁻¹

f'(x) = x⁻²-12x⁻⁵

Express as a fraction

f'(x) = 1/x²-12/x⁵

To get f'(4), we will have to substitute x = 4 into the resulting expression

f'(4) = 1/4²-12/4(5)

f'(4) = 1/16-12/20

f'(4) = 1/16-3/5

Find the LCM

f'(4) = (5-48)/80

f'(4) = -43/80

Note that the function used was assumed but the same method can be employed to any other functions.

The graph of an inequality has an open circle at 3.9, and the ray moves to the right. What inequality is graphed?

Answers

Answer:

The required inequality is x > 3.9

Step-by-step explanation:

Consider the provided information.

The closed circle means that the set contain that extreme.

For closed circle we use the inequality "≤" or "≥"

The open circle means that the set does not contain that extreme.

For open circle we use the inequality "<" or ">"

Here, it is given that the graph has an open circle, therefore the required inequality should be "<" or ">"

If the ray moves right, in the usual notation, the real numbers increase to the right, if it moves to left the real numbers decreases.

It is given that the ray moves to right that means the set of numbers bigger than 3.9, that does not contain the number 3.9

Hence, the required inequality is x > 3.9

Where x is any number greater than 3.9.

The answer would be x > 3.9

Evaluate (3+8i)(-2-i)

Answers

Answer:

2 - 19i

Step-by-step explanation:

note that i² = - 1

given

(3 + 8i)(- 2 - i) ← expand using FOIL

= - 6 - 3i - 16i - 8i²

= - 6 - 3i - 16i - 8(- 1)

= - 6 - 3i - 16i + 8 ← collect like terms

= 2 - 19i

How do you find the value of x or y so that the line through the points has a given slope?

Answers

We can make a linear equation system to deduce it.

$\left \{ {{y_1=ax_1+b~(I)} \atop {y_2=ax_2+b~(II)}} \right. \n \n (II)-(I): y_2-y_1=a(x_2-x_1) \n \n \boxed {a= (\Delta x)/(\Delta y) }$

ok so if you had the points
(x1,y1) and (x2,y2)
slope=rise/run so
slope=(y2-y1)/(x2-x1)

Ryan was adding numbers on a number line. He started at –3 and then he added +2. He wrote that his answer was –5 . Is Ryan's answer reasonable?

A.
No, it is not reasonable because if you start at –3, you will move 2 spaces to the right and get –1.

B.
No, it is not reasonable because if you add two integers, you get a positive integer. The answer is +5.

C.
Yes, it is reasonable because if you start at –3, you will move 2 spaces to the left and get –5.

Answers

The answer is A because it is -1 because it would go to the right when you add two
