For the function f(x) = (5-6x)^2, fine f^-1

Scorpion4ik [409]

Answer:

f(-1) = 121

Step-by-step explanation:

f(x) = (5-6x)^2 (First we will substitute x for -1)

f(-1) = (5-6(-1))^2 (Then we will combine like terms)

f(-1) = (11)^2 (Then we will square it)

f(-1) = 121 (You are done)

What is the equation of a line that passes through the point (6, 1) and is perpendicular to the line whose equation is y=−2x−6y=

Mandarinka [93]

Lets get the negative reciprocal of the slope so we get
$m = \frac{1}{2}$
Now the equation that is perpendicular is
$y = \frac{1}{2} x + b$
Lets solve for b by plugging in the point (x,y)=(6,1)
$1 = \frac{1}{2} (6) + b \\ 1 = 3 + b \\ 1 - 3 = b \\ b = - 2$
Now plug that into the equation. So the equation of the line that is perpendicular and
passes through the point (6, 1) is
$y = \frac{1}{2} x - 2$

Albert is growing tomato plants and studying their heights. He measured Plant A at 3 7/8 feet. He measure Plant B at 2 1/4 feet.

mr_godi [17]

Answer: Albert is wrong

Step-by-step explanation:

You first have to subtract Plant B's measurement from Plant A's measurement.

3 7/8-2 1/4 => 3 7/8-2 2/8

If you solve it you get 1 5/8. Since it cannot be reduced this is the final answer.
