Let x = the number

Let c = the factor

You want

√(cx) = 2√x

Solve for c:

cx = 4x

c = 4

You need to multiply by 4 to double the square root. Have a great day!!

when there are equal forces from opposite directions acting on an object the forces are said to be which of the following

svetoff [14.1K]

Answer: Balanced Forces

Step-by-step explanation:

Since both of the forces are equal and going opposite directions on an object, the object will not move and the forces are then identified as Balanced Forces. Therefore, the net force is equal to 0.

Find the equation of the line that passes through (1,2) and is perpendicular to y=2x+3. Leave your answer in the form y=mx+c

zhenek [66]

Answer:

y = -1/2x + 5/2

Step-by-step explanation:

If two lines are perpendicular to each other, they have opposite slopes.

The first line is y = 2x + 3. Its slope is 2. A line perpendicular to this one will have a slope of -1/2.

Plug this value (-1/2) into your standard point-slope equation of y = mx + b.

y = -1/2x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (1, 2). Plug in the x and y values into the x and y of the standard equation.

2 = -1/2(1) + b

To find b, multiply the slope and the input of x (1)

2 = -1/2 + b

Now, add 1/2 to both sides to isolate b.

5/2 = b

Plug this into your standard equation.

y = -1/2x + 5/2

This equation is perpendicular to your given equation (y = 2x + 3) and contains point (1, 2)

Hope this helps!
