Answer:

AS IT IS RIGHT ANGLE .

THEREFORE, 1 ANGLE =90°

A=55°,

LET LAST ANGLE BE Y.

THEREFORE, Y=90-55=35°

RATIO OF A:Y=55:35=11/7

RATIO OF ANÔTHER SIDE :X=11:7

HYPOTENOUES=8

THEREFORE8^2=11X^2+7X^2

Please help me out with this problem!
MA_775_DIABLO [31]

Answer:

C

Step-by-step explanation:

The red graph is the graph of y = f(x) shifted 1 unit right and then reflected in the x- axis.

Given y = f(x) then f(x + a) is a horizontal translation of a units

• If a > 0 then shift to the left of a units

• If a < 0 then shift to the right of a units

Here shift to the right of 1 unit, thus

y = f(x - 1)

Under a reflection in the x- axis

a point (x, y ) → (x, - y )

Note the y- coordinates are the negative of each other, thus

- y = f(x)

Now \frac{y}{-1} = - y, hence

The equation for the red graph is

\frac{y}{-1} = f(x - 1) → C
