sin x + x · cos x + cos x

Step-by-step explanation:

f(x) = u · v → f'(x) = u' · v + u · v'

f(x) = (x + 1) sin x

f'(x) = 1 · sin x + (x + 1) · cos x

f'(x) = sin x + x · cos x + cos x

Answer:

45

Step-by-step explanation:

First add the angles given: 85+50=135

Since all the angles of a triangle combined have to equal 180, you can subtract it from 180.

180-135=45

So your answer would be 45.

The statement that correctly compares the function shown on the graph with the function y=4x + 2 is 'The function shown on the graph has a smaller rate of change, but a higher starting point.'

The rate at which one quantity is changing with respect to another quantity.

For given question;

It is given a function y = 4x + 2

This function represents a line.

We have slope of the line = 4 and y - intercept = 2

We already know that the rate of change of line is given by its slope.

So, the rate of change of given function ;

y = 4x + 2 is 4.

The starting point of function f(x) is 2.

The graph of the line passing through points (-1, 1) and (0, 4)

So using slope formula,

m = (4-1)/ 0-(-1)

m = 3

So, the rate of change of function is 3.

The rate of change of function shown on the graph is smaller than the rate of change of function y = 4x + 2

Thus, the statement that correctly compares the function shown on the graph with the function y=4x + 2 is 'The function shown on the graph has a smaller rate of change, but a higher starting point.'

Hence, The correct answer is option (A)

Answer:

X = 8⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Answer:

Step-by-step explanation:

[tex]13x-\dfrac{1}{2}(4x + 50) = 8x - 1\\\\13x -\dfrac{1}{2}*4x - \dfrac{1}{2}*50 = 8x - 1[/tex]

13x  - 2x  - 25 = 8x - 1

11x - 25 = 8x - 1

11x = 8x - 1 + 25

11x- 8x = 24

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

The number of 1/3 cups of servings in 10/3 cups of dried beans is 10 cups of servings.

i.e

= 10/3 ÷ 1/3

= 10/3 x 3/1

=  10/3 x 3

= 3

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example: 1/2, 1/3 is a fraction.

We have

Number of dried beans = 10/3 cups

The number of 1/3 cup servings can be found by dividing the total number of cups of dried beans by 1/3.

The number of 1/3 cup servings:

= Number of dried beans cups ÷ 1/3

= 10/3 ÷ 1/3

= 10/3 x 3/1

= 10 cups servings

Thus,

The number of 1/3 cups of servings in 10/3 cups of dried beans is 10 cups of servings.

Answer:

Jacob lost the biggest percentage of his starting weight.

Jacob: 8%

Timothy: 6.4%

Hamza: 7.5%

Formula: (initial weight - new weight)/initial weight times 100.

Step-by-step explanation:

Jacob: 225 pounds - 207 pounds = 12 pounds

x/100 = 12/225

= 1800/225

= 8%

Timothy: 200 pounds - 188 pounds = 12 pounds

x/100 = 12/188

= 1200/188

= 6.4%

Hamza: 280 pounds - 259 pounds = 21 pounds

x/100 = 21/280

= 2100/280

= 7.5%

x = 5 and y = 8

Step-by-step explanation:

→ Subtitute the value of y to second equation :

4x - 5y = -20

4x - 5(3x - 7) = -20

4x - 15x + 35 = -20

-11x + 35 = -20

-11x = -20 - 35 → (multiplied by -1)

11x = 20 + 35

11x = 55

x = 5

→ Subtitute x to one of Equation :

For example i take from First Equation…

y = 3x - 7

y = 3(5) - 7

y = 15 - 7

y = 8

∴ So, the value of x = 5 with y = 8
