Figure MNPQR will be reflected across the x-axis to create figure M'N'P'Q'R'. Which rule describes this transformation? A.(x,y)

kolbaska11 [484]

Answer:

D.(x,y) → (x,-y)

Step-by-step explanation:

If it is reflected across the X-axis, then the X variable will stay the same and the Y variable will change.

I hope this helps!! Good luck!!

(Sorry if I'm wrong! It's kinda awkward because it is placed in the second quadrant instead of the first.)

A triangle has a hypotenuse of 2.9ft and a leg of 2.6ft. Find the smallest angle.

OleMash [197]

Answer:

Lowest angle of the triangle with hypotenuse of 2.9ft and a leg of 2.6ft is 26.29°.

Explanation:

A triangle has a hypotenuse of 2.9ft and a leg of 2.6ft

We have smallest angle = Angle C

We have, Cos C = AC/BC

= 2.6/2.9

= 0.897

C = 26.29°

So lowest angle of the triangle with hypotenuse of 2.9ft and a leg of 2.6ft is 26.29°.

Given that f(x) = x2 – 12x + 27 and g(x) = x – 9, find (f.g)(x) and express

nikklg [1K]

Step-by-step explanation:

$f(x) = {x}^{2} - 12x + 27 \\ g(x) = x - 9 \\ (f \times g)(x) = ( {x}^{2} - 12x + 27)(x - 9) \\ (f \times g)(x) = {x}^{3} - 9 {x}^{2} - 12 {x}^{2} + 108x + 27x - 243 \\ (f \times g)(x) = {x}^{3} - 21 {x}^{2} + 135x - 243$
