What is the perimeter of the triangle
damaskus [11]

Answer:30 centimeters

Step-by-step explanation:

The bigger square with an area of 144 cm squared has a perimeter of 100 with each side equal to 25. You find this by seeing that 25 times 25 equals the area of the square. Same thing with the smaller square 5 times 5 equals 25. Now that we have the perimeter for the sides that are connected to the square (25) and (5), multiply those together just as you would with finding the area of a square. (25)(5)=60. Since this is a triangle you divide your answer in half which is 30.

In two or more complete sentences, identify the parent function, and describe the transformations that were applied to
pantera1 [17]

Answer:

Step-by-step explanation:

Transformed of the function has been given as,

f(x) = \sqrt{(2x+6)}+3

     = \sqrt{2}(\sqrt{x+3})+3

Parent function of this transformed function = \sqrt{x}

Vertical stretch = By a factor of \sqrt{2}

Horizontal shift = 3 units to the left

Vertical shift = 3 units up

Now we can summarize these transformations as,

1). Parent function g(x) = \sqrt{x} has been vertically stretched by a factor of \sqrt{2}

2). Followed by the translations of 3 units left and 3 units up.

I need help with this math problem
mr Goodwill [35]

Let X = number of minutes.

Plan A = 50 + 0.04X

Plan B = 60 + 0.02X


50 + 0.04X = 60 + 0.02X

Subtract 50 from each side:

0.04X = 10 + 0.02X

Subtract 0.02X from each side:

0.02X = 10

Divide both sides by 0.02

X = 10 / 0.02

X = 500

It will take 500 minutes.
