Answer:

  (c)  52.0

Step-by-step explanation:

The angle whose cosine is 8/13 is found using the inverse cosine function:

  y° = arccos(8/13) ≈ 52.0°

  y ≈ 52.0

__

The calculator button to compute this value is probably labeled cos⁻¹. You may need to access the function using a <em>Shift</em> or <em>2nd</em> key. The calculator must be set to degrees mode to prevent the answer from appearing in radians or grads. If you use a spreadsheet, your formula may look like ...

  =DEGREES(ARCCOS(8/13))

Graph the line that represents a proportional relationship between yyy and xxx where the unit rate of change of yyy with respect
My name is Ann [436]

Answer:

y=\frac{4}{3}x

The graph in the attached figure

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m or unit rate of the line and the line passes through the origin

so

In this problem we have

k=\frac{4}{3}

substitute

y=\frac{4}{3}x

using a graphing tool

Can someone help me find the relative maximum and minimum? please i really need help
bearhunter [10]

9514 1404 393

Answer:

  • relative maximum: -4
  • relative (and absolute) minimum: -5

Step-by-step explanation:

The curve has a relative maximum where values on either side are lower. This looks like a peak in the curve. There is one of those on the y-axis at y = -4.

The relative maximum is -4.

__

A relative minimum is a low point, where the curve is higher on either side. There are two of these, located symmetrically about the y-axis. The minimum appears to be about y = -5. (They might be at x = ± 1, but it is hard to tell.)

The relative minima are -5.

__

A minimum or maximum is absolute if no part of the curve is lower or higher. Here, the minima are absolute, while the maximum is only relative. (The left and right branches of the curve go higher than y=-4.)

_____

Identifying the points on the curve should be the easy part. Deciding what the coordinates are can be harder when the graph is like this one.
