Find the derivative of f(x) = negative 8 divided by x at x = 11.

Answers

Answer 1

Answer: I think it’s

f ` (x) = - 8 / x²

f ` (11) = - 8 / 121

Answer 2

The value of the derivative at x = 11 is 8/121

The equation of the function is given as:

[tex]f(x) = -\frac 8x[/tex]

Rewrite the above equation as:

[tex]f(x) = -8x^{-1}[/tex]

Using the first principle, the derivative of f(x) is:

[tex]f'(x) = -1 \times -8x^{-1-1}[/tex]

[tex]f'(x) = -1 \times -8x^{-2}[/tex]

Evaluate the product

[tex]f'(x) = 8x^{-2}[/tex]

Rewrite the above equation as:

[tex]f'(x) = \frac{8}{x^2}[/tex]

Substitute 11 for x

[tex]f'(11) = \frac{8}{11^2}[/tex]

[tex]f'(11) = \frac{8}{121}[/tex]

Hence, the value of the derivative at x = 11 is 8/121

Which expression has the same value as 8 – (-1)?​

Answers

Answer: 9

Step-by-step explanation:

Two negatives make a positive. So the expression 8-(-1) is equal to 9, because the two subtraction signs the equation create an addition sign, and the equation becomes 8 + 1.

Therefore, 9 has the same value as 8-(-1).

Max car holds 18 gallons of gasoline driving on the highway the car uses approximately 2 gallons per hour. let H represent the number of hours max has been riding on the highway. write an expression that shows how many gallons of gasoline Max has left after driving H hours. then find the number after max drives 3.5 hours on the highway.

Answers

y= 18 gallons-2(h)
y is what you're trying to find out and since there are 18 gallons in the tank after every hour you would have 2 less gallons. So, you can multiply how many hours he's been driving by the 2 gallons and subtract it from 18

Adam purchased some items at the school store. He bought 3 pencils for $0.15 each and 5 single-subject notebook
If these items cost a total of $6.45, what was the cost of each notebook?
O A. $1.20
B. $1.26
O c. $1.29
OD. $1.38

Answers

Answer:

The answer is A

Step-by-step explanation:

Fist multiply 3 and .15 to get .45 for 3 pencils. Then subtract .45 from 6.45 and get 6. Then divided 6 by 5 to get 1.2 for each book

i think the answer is a: $1.20

my work:

3 x 0.15 = 0.45.

6.45 - 0.45 = 6.00

6.00 / 5 = 1.20

and i checked my work by doing 1.20 x 5 + 0.40 = $6.45.

21 square feet

Step-by-step explanation:

To find out the area of this irregular figure, divide it into two rectangles and add their areas.. This can be done in two ways.

Version 1: 6 * 2 rectangle and 3 * 3 square

(6 * 2) + (3 * 3)

12 + 9

21 sq. ft.

Version 2: 5 * 3 rectangle + 2 * 3 rectangle

(5 * 3) + (2 * 3)

You could really just do 7 * 3 here.

7 * 3

21 sq. ft.

Either way, you still get 21 square feet as your answer.

whats the answer to 3x+4=6x+19

Answers

Answer:

x = -5

Step-by-step explanation:

[tex]3x + 4 = 6x + 19\\-3x + 4 = 19\\-3x = 15\\x = -5[/tex]

3x+4=6x+19 subtract 3x from both sides
4=3x+19 subtract 19 from both sides
-15=3x divide by 3 on both sides
-5=x
