How would you describe the relationship between the real zeros and x-intercepts of the function y = log (x-2)?
lakkis [162]

Answer:

When you set the function equal to zero, the solution is x = 3; therefore, the graph has an x-intercept at x = 3.

Step-by-step explanation:

The given function is y=\log (x - 2).

So, for real zeros and x-intercept, the y-coordinate must be equal to zero.

Then it becomes 0 = \log (x-2)

⇒ x - 2 = 1 {Since log 1 = 0}

⇒ x = 3

Therefore, when you set the function equal to zero, the solution is x = 3; therefore, the graph has an x-intercept at x = 3. (Answer)

5w=5×10 to the second power
torisob [31]
Hey there!


5 x w = 10 to the second power . . .

10 x 10 = 100

5 x 100 = 500

5 x w = 500

500 = 5w

w = 100 <-------

Hope this helps you.
Have a great day!

The length of a rectangle is six times its width. If the area of the rectangle is 384^2, find its perimeter.
Leno4ka [110]

Answer:

Perimeter, P = 112 meters

Step-by-step explanation:

  • Let the length of the rectangle be L.
  • Let the width of the rectangle be W.

Translating the word problem into an algebraic expression, we have;

L = 6W  ...... equation 1

<u>Given the following data;</u>

  • Area of rectangle = 384 m²

To find the perimeter of the rectangle;

First of all, we would determine the dimensions of the rectangle using its area.

Mathematically, the area of a rectangle is given by the formula;

Area of rectangle = LW  ..... equation 2

Substituting eqn 1 into eqn 2, we have;

384 = 6W(W)

384 = 6W²

Dividing both sides by 6, we have;

W² = 384/6

W² = 64

Taking the square root of both sides, we have;

W = √64

Width, W = 8 meters

Next, we would find the length;

L = 6W

L = 6 * 8

Length, L = 48 meters

Lastly, we would determine the perimeter of the rectangle using the above dimensions;

Mathematically, the perimeter of a rectangle is given by the formula;

Perimeter = 2(L + W)

Substituting the values into the formula, we have;

Perimeter, P = 2(48 + 8)

Perimeter, P = 2(56)

<em>Perimeter, P = 112 meters</em>
