Which graph shows the same end behavior as the graph of f(x) = 2x6 - 2x2 - 5?

aleksandrvk [35]

Step-by-step explanation:

End behavior of a polynomial function is the behavior of the graph of f(x) as x tends towards infinity in the positive or negative sense.

Given function:

f(x) = 2x⁶ - 2x² - 5

To find the end behavior of a function:

Find the degree of the function. it is the highest power of the variable.

Here the highest power is 6

Find the value of the leading coefficient. It is the number before the variable with the highest power.

Here it is +2

We observe that the degree of the function is even

Also the leading coefficient is positive.

For even degree and positive leading coefficient, the end behavior of a graph is:

x → ∞ , f(x) = +∞

x → -∞ , f(x) = +∞

The graph is similar to the attached image

What is the greatest common factor of 40 and 27?

Olenka [21]

To find the greatest common factor of 40 and 27, we can first start by making a list of factors for each number.

The factors of 27 are: 1, 3, 9, 27

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40

When looking at these numbers, we can see that 1 is the greatest common factor of both 40 and 27.

Plssssss help fast!!!!Launching From a Tower

aleksandrvk [35]

Answer:

A. h = 64

B. t = 4 -> 4 seconds

C. t = 1.5 -> 1.5 seconds

D. maximum height is 100 ft

E. The domain that makes sense for the function in this context is t

is any positive real number since time can not be negative.

Step-by-step explanation:

h = -16t2 + vt + 64

A. What tower platform height was the projectile launched from?

when the projectile was not launched, t = 0

h = -16(0)^2 + v(0) + 64 = 64

B. How long was the projectile in the air?

if the projectile lands, its height = 0 so substitute 0 for h

0 = -16(t)^2 + 48(t) + 64

= -16(t^2 - 3t - 4)

= -16(t - 4)(t + 1)

t = 4 or t = -1

Since time can not be negative, t = -1 can not be the answer. Therefore, the projectile lands when t = 4 or 4 seconds.

C. When did it reach its maximum height?

maximum -> t=-b/2a where in -16(t)^2 + 48(t) + 64, b = 48 and a = -16

t = -48/-32 = 1.5

D. What was its maximum height?

plug t = 1.5 into -16(t)^2 + 48(t) + 64

-16(1.5)^2 + 48(1.5) + 64 = -36 + 72 + 64 = 100

E. The domain that makes sense for the function in this context is t

is any positive real number since time can not be negative.

The line passing through which two points is parallel to the line x - 2y = 16?

Naddika [18.5K]

Answer:

E) -4,7 and -2,8

Step-by-step explanation:

parallel lines have same slope

x - 2y = 16

y = 1/2 x -8 slope: 1/2

E. slope = Δy / Δx = (8-7) / (-2 - -4) = 1/2
