1. Evaluate the following expression:

stira [4]

Answer:

1. 37, 2. 1 2/5

Step-by-step explanation:

For Question 1:

Step 1: Replace the x values

x= 3, y=5

Now you get...

9x + 2y ---> (9 x 3) + (2 x 5)

(Remember, if an x value is beside a number, and it is replaced, that replaced number is to be multiplied with the number the previous x value was.)

Parentheses first, Multiplication second, Addition third (look at PEMDAS below :) )

Step 2: Multiply and Add

(9 x 3) + (2 x 5)

27 + 10

For Question 2:

Step 1: Replace the x and y values

m = 1, p = 5

Now your equation should look like this:

m + p ÷ 5 ---> 1 + 2 ÷ 5

Now, which one to do first? Use the PEMDAS strategy

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

You have to do it from top to bottom

Division comes first, which means, you have to divide first, then add:

2 ÷ 5 = 2/5

2/5 + 1 = 1 2/5

Hope this helps :)

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

Nimfa-mama [501]

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

Triangle GHJ and its image, triangle G’H’J’, are graphed on the coordinate grid below. On a coordinate plane, triangle G H J has

Ipatiy [6.2K]

The rotation is 90° counter clockwise.

Step-by-step explanation:

Triangle GHJ has the points G(2,5), H(3,3) and J(1,4)

And the coordinates changes after 90° counterclockwise rotation,

the points are changed from (x,y) to (-y, x) ,

so the triangle G'H'J' has the points G'(-5,2), H'(-3,3), J'(-4,1).
