Use an equation to find the value of k so that the line that passes through the given points has the given slope. (

shutvik [7]

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (4, -4) and (k, -1) and the slope m = 34.

Substitute:

$\dfrac{-1-(-4)}{k-4}=34\\\\\dfrac{3}{k-4}=\dfrac{34}{1}\qquad|\text{cross multiply}\\\\34(k-4)=3\qquad|\text{use distributive property}\\\\34k-136=3\qquad|+136\\\\34k=139\qquad|:34\\\\k=\dfrac{139}{34}$

Answer:

Step-by-step explanation:

Please see the answer in the picture attached below.

" From Step 1: We find that Angle N1 equals to 75 gradius => Answers A and C wrong. Answers B and D are left.

" From Step 4: We find that Angle N2 equals to 129 gradius => Answer B is true.

You don't need to find the exact value of the angle N3 in oder to choose the right answers from A,B,C,D.

Hope this answer can help you. Have a nice day!

3. Nancy and Harry are sliding a stone statue and moving it to a new location in their garden. Nancy is pushing the statue with

Elis [28]

Answer:

197,8879 N.

Step-by-step explanation:

The magnitude of the horizontal force exerted on the statue can be calculated using trigonometric functions.

The question given says that Nancy is pushing the statue with a force of 120 N at a 60° angle to the horizontal and Harry is pulling the statue with a force of 180 N at a 40° angle with the horizontal.

With that information can be calculated the horizontal force exerted on the statue by Nancy, the horizontal force exerted on the statue by Harry and, adding that results, the total horizontal magnitude can be calculated.

The cosine function can be used to calculate the horizontal component of the forces exerted by Nancy and Harry, to determine the horizontal component of the force exerted on the statue.

F= (120 N cos 60°) + (180 N x cos 40°)

F= 197,8879 N

7.19 divided by 58 estimate the quotients

lozanna [386]

Answer:

0.124

Step-by-step explanation:

$\frac{7.19}{58}$

To divide the numbers, we need to remove the decimal point

To remove decimal point , we multiply top and bottom by 100

$\frac{719}{5800}$

Use long division. After using decimal point at the top we can include any number of zeros with 719

. 1 2 3 9

---------------------

5800 7190

5800

------------------------(subtract)

13900

Division goes on ............

Estimate the quotient to 3 decimal places

Quotient = 0.124
