Answer:

√89

Step-by-step explanation:

Can someone help me with this ​
Nataly_w [17]

Answer:

  b, e

Step-by-step explanation:

a, b) ordinarily, we claim the variable on the vertical axis is a function of the variable on the horizontal axis. By that claim, <em>temperature is a function of time</em>.

If the graph passed the horizontal line test (a horizontal line intersects in one place), then we could also say time is a function of temperature. The graph does not pass that test, so we cannot make that claim.

c) The graph has negative slope between 4:00 and 5:00. Temperature is decreasing in that interval, not increasing.

d) The graph has two intervals in which it is horizontal: 5:00-9:00 and 11:00-12:00. In those intervals it is neither increasing nor decreasing.

e) The graph shows a minimum in the interval 11:00-12:00. <em>The lowest temperature first occurs at 11:00</em>.

Answer:

  15.71 units

Step-by-step explanation:

The arc length is given by the formula ...

  s = rθ

where r represents the radius, and θ represents the central angle in radians.

The angle of 60° is π/3 radians, so the arc length is ...

  s = 15(π/3) = 5π ≈ 15.71 . . . units

  LN ≈ 15.71 units

__

<em>Note</em>: if you use 3.14 for π, you will get 15.70.
