Which is a stretch of an exponential decay function ?
sergiy2304 [10]

Using translation concepts, a stretch of a decay exponential function is given by:

f(x) = 5\left(\frac{1}{5}\right)^x

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

An exponential decay function is given by:

y = ab^x

In which |b| < 1.

A stretch means that the function is <u>multiplied by a factor with absolute value greater than 1</u>, hence the function would be given by:

f(x) = 5\left(\frac{1}{5}\right)^x

please help really simpleeeeeeeeeeeee plsssss help really simple i am just checking my awnser pease tell me what would the coord
Furkat [3]

Answer:

P(-1, 0); Q(0, -1); R(2, -1).

Step-by-step explanation:

When you reflect coordinates over the y-axis, the y-coordinates do not change, while the signs of the x-coordinates are flipped. You can see the example attached!

And so, after reflecting P'(1, 0), you would get P(-1, 0) because the sign of the x-value is flipped and the y-value does not change.

Q'(0, -1) becomes Q(0, -1) because 0 is neither negative nor positive, and the y-value does not change.

R'(-2, -1) becomes R(2, -1) because the sign of the x-value is flipped to positive and the y-value does not change.

Hope this helps!

Find the perimeter of a rectangle with a length of
Luba_88 [7]

Answer:

P = 8\sqrt{2} + 10 + 2\sqrt{6}

Can only be simplified through calculator using decimal equivalents.

Step-by-step explanation:

The perimeter of a rectangle is the formula P=2l+2w. Here l=4\sqrt{2} and w=5+\sqrt{6}. So the perimeter is:

P= 2l+2w\\P = 2(4\sqrt{2} ) + 2(5+\sqrt{6} )\\P = 8\sqrt{2} + 10 + 2\sqrt{6}
