The function y = x2 - 4x + 8 approximates the height, y, of a bird, and its
horizontal distance, x, as it flies from one fence post to another. all distances
are in feet. complete the square to find and interpret the extreme value
(vertex).
select two answers: one extreme value and one interpretation.
height (feet)
distance (feet)
a. minimum at (2,4)
o
b. when the bird is 2 feet away from the first fence post, it reaches
its minimum height of 4 feet.
i c. minimum at (4,8)
i
d. when the bird is 4 feet away from the first fence post, it reaches
its minimum height of 8 feet.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
