If you apply the changes below to the absolute value parent function,
QveST [7]

Answer:

F(x) = |x|

And we need to apply some transformations. The first part is hift 8 units left. And we need to do this:

F(x) = |x+8|

Then we need to apply the second transformation Shift 3 units down. and we can do this:

F(x) = |x+8|-3

Step-by-step explanation:

For this case we have the following function given:

F(x) = |x|

And we need to apply some transformations. The first part is hift 8 units left. And we need to do this:

F(x) = |x+8|

Then we need to apply the second transformation Shift 3 units down. and we can do this:

F(x) = |x+8|-3

In ΔCDE, the measure of ∠E=90°, the measure of ∠D=23°, and EC = 1.3 feet. Find the length of DE to the nearest tenth of a foot.
BabaBlast [244]

Answer: length of DE is about 3.3 ft

Step-by-step explanation:  A calculator is necessary!

DE is the unknown hypotenuse of the triangle

get the sine of 23° = 0.3907311285

Use the equation for sine

<em>sin = o/h</em> .

To find h,  Substitute values for sin and o.  O is EC, Opposite the 23° angle D

<em>0.3907311285 = 1.3/h</em> multiply both sides by h

h(0.3907311285) = 1.3 divide both sides by 0.3907311285

h = 1.3/0.3907311285

3.327096065 = h, the length of the hypotenuse, DE.
