Answer:

f(11) = 9

Step-by-step explanation:

f(x) = 1/4(5-x)^2

f(x) = 1/4 (5-11) ^2

f(11) = 1.25 - 2.75 ^2

f(11) = 9

Answer:

<h2><em><u>-15</u></em></h2>

Step-by-step explanation:

(\sqrt{20} - 2\sqrt{45} +\sqrt{5} )*\sqrt{5}

=  \sqrt{20}  \times  \sqrt{5}  - 2 \sqrt{45}  \times  \sqrt{5}  +  \sqrt{5}  \times  \sqrt{5}

=  \sqrt{100}  - 2 \sqrt{225}  +  \sqrt{25}

= 10 - 2 × 15 + 5

= 10 - 30 + 5

= 15 - 30

=<em><u> -15 (Ans)</u></em>

A line segment with endpoints (5,8) and (-6,8) is rotated around the origin 270 clockwise how long will the new segment be?
aliina [53]

A rotation doesn't change the length of anything.

The length of the rotated line segment would be the same as the original line segment.

Because both Y values are the same, you just need to calculate the length of the X values.

5 to 0 = 5

0 to -6 = 6

Total length = 5 +6 = 11 units long.

What’s the answer to this
pantera1 [17]

Answer:

A

Step-by-step explanation:

Given f(x) the f(x) + c represents a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here c = - 6, thus a shift down, thus

g(x) = x² - 6  → A
