Answers

For this derivative, you could set

[tex]\boxed{u = x^2 - 4x}[/tex]

Then

[tex]y = \sin(x^2-4x) = \sin(u)[/tex]

so that

[tex]\boxed{\dfrac{\mathrm dy}{\mathrm du} = \cos(u)}[/tex]

and

[tex]\boxed{\dfrac{\mathrm du}{\mathrm dx} = 2x - 4}[/tex]

Then the chain rule gives

[tex]\dfrac{\mathrm dy}{\mathrm dx} = \dfrac{\mathrm dy}{\mathrm du}\dfrac{\mathrm du}{\mathrm dx} \\\\ \dfrac{\mathrm dy}{\mathrm dx} = \cos(u)(2x-4) \\\\ \boxed{\dfrac{\mathrm dy}{\mathrm dx} = (2x-4)\cos(x^2-4x)}[/tex]

What is the equation of this line?

y=3/4x+2

y=4/3x−2

y=3/4x−2

y=−3/4x−2

Answers

Answer:

y=3/4x-2

Step-by-step explanation:

Y-Intercept is -2 so it can't be the first option.

Then for the slope it goes up 3 and over 4. So the slope is 3/4.

So the equation is y=3/4x-2

Determine the equation of the line passing through the point (4,5) ​with the slope equal to 2.

Answers

Answer:

 y=2x-3

Step-by-step explanation:

slope (m)= 2

The Slope intercept of the line passing through (4,5) is

y=mx+b

5 = 2(4) + b

5 = 8 + b

b = -3

The equation of the line passing through pt. (4,5) is  

 y= mx+b

If fat contains 9 calories per gram, what is the maximum number of grams of fat he should consume? Give me a whole number or decimal rounded to one decimal place. Thanks! Expert only please.

Answers

Answer:-

According to the question, therefore, the maximum number of grams of fat he should consume will be 76.3 grams.

Step-by-step explanation:-

Directly divide 687 by 9 as both are fat content. Therefore, by dividing them, we get to know about how grams of fat can be consumed.

A jacket is on sale for 15% off. If
the original price is $165, how much
would you save by buying it on sale?
A. $ 15.00
B. $ 24.75
C. $140.25
D. $189.75
E. $247.50

Answers

B is the only right answer

Answer:

$24.75

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 165 × 15/100

Discount = 165 x 0.15

You save = $24.75

Final Price = Original Price - Discount

Final Price = 165 - 24.75

Final Price = $140.25

Choose an equation that would be used to solve

0 = -x^2 + 10x -8


(x+25)^2 = -8

(x-5)^2 = 17

(x-10)^2 = 25


Answers

The equation that would be used to solve the function is (x+5)^2 = 17

Given the quadratic equation -x^2 + 10x -8 = 0

This can also be written as:

-x^2 + 10x -8  = 0

x^2 - 10x + 8 = 0

x^ 2- 10x  = -8

The coefficient of x is -10

Half of the coefficient of -10 = -10/2 = -5

Square the result = 5^2 = 25

Add 25 to both sides of the equation

x^2 - 10x + 25 = -8 + 25

x^2 - 10x + 25 = 17

(x+5)^2 = 17

Hence the equation that would be used to solve the function is (x+5)^2 = 17

James uses 1 1/2 cups of milk and 2 1/4 cups of flour for his favorite cookie recipe. This makes 60 cookies. How much milk and flour would he need to make 40 cookies?

Answers

Answer:

to get you answer you would have to add 1 1/2 and 2 1/4, then your equation would be 60 ÷ 3 3/4 , then whatever your total is, multiply that by 40 and that would be your answer

The amount of milk and flour (x) that he needs to make 40 cookies will be 5/2 cups.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

James uses 1 1/2 cups of milk and 2 1/4 cups of flour for his favorite cookie recipe. This makes 60 cookies.

The amount of milk and flour will be

⇒ 1  1/2 + 2  1/4

⇒ 3/2 + 9/4

⇒ 15/4

Then the amount of milk and flour (x) that he needs to make 40 cookies will be

x / (15/4) = 40 / 60

x = 5/2 cups

The amount of milk and flour (x) that he needs to make 40 cookies will be 5/2 cups.
