Minus 1 both sides
x²-8x=-1

take 1/2 of the linear coefient and square it
-8 is the linear coefient
-8/2=-4, (-4)²=16
add 16 to both sides

x²-8x+16=16-1
factor perfect squaer trinomial
(x-4)²=15
square root both sides, remember to take positive and negative roots
x-4=+/-√15


not exactly sure what to put in the blnaks

but
the solutions are x=4+√15 and x=4-√15

Which of the following describes the end behavior over the domain of the square root function graphed above?
krok68 [10]

Answer:

A.

As x decreases in value, f(x) decreases in value.

As x increases in value, f(x) increases in value.

Step-by-step explanation:

As we move our eyes towards the right following the curve, we see that the y-values are larger and larger. As we move to the right following the curve, the values of the x-variable in the horizontal axis are increasing. Then as x increases, the values of f(x) also increase.

On the other hand, if we move our eyes to the left following the curve, this way looking into what values the function adopts for smaller and smaller values of x, we see that the f(x) values decrease (the curve goes down).

Then, to summarize:

a) As we move to the right, thus increasing the values of x, we see the values of f(x) increase

b) As we move to the left, thus decreasing the values of x, we see the values of f(x) decrease.

A 32 foot ladder is leaning against a building and forms a 29.37 angle with the ground how far away from the building is the bas
Ber [7]

In the picture below, h is height of building and x is the distance the base of the ladder is away from the base of the building.

We use trigonometry to find x, particularly the cosine function.

cos(29.37°) = x/32

cos(29.37°)(32) = x

27.8870633052 = x

We now round off to the nearest hundredths, which means to two decimal places.

27.89 feet = x
