Answer:

$x < 2.5$

Step-by-step explanation:

$- 4x + 5 > - 5 \\ - 4x > - 5 - 5 \\ - 4x > - 10 \\ \frac{ - 4x}{ - 4} > \frac{ - 10}{ - 4} \\ x < \frac{5}{2} \\ x < 2.5$

hope this helps

Answer:

C. Yes Devon should have evaluated f(3).

Step-by-step explanation:

She substituted the wrong value. For x - 3 to be a factor f(3) must equal 0.

f(3) = 3^3 + 3^2 - 10(3) + 8 = 27 + 9 - 30 + 8

= 14, so x- 3 is not a factor anyway but she did substitute the wrong value.

Answer:

Period = $\frac{2}{3}$

The Ferris wheel will complete one round in 40 seconds.

Step-by-step explanation:

We have the function representing the height of the passenger by,

$h=82.5 \sin 3\pi(t+0.5)+97.5$ , where t = time in minutes.

It is known that when a function f(x) has period P, then the function a×f(bx+c)+d will have the period $\frac{P}{|b|}$ .

Since, the function $\sin x$ has period $2\pi$ , so the function h will have period $\frac{2\pi}{3\pi}$ i.e. $\frac{2}{3}$ .

Thus, the period of the given function is $\frac{2}{3}$ .

Now, as the period is $\frac{2}{3}$ minutes i.e 40 seconds.

Hence, we get that the Ferris wheel will complete one round in 40 seconds.
