Step-by-step explanation:

-2.1 = 2.5z - 2.6

-2.1 + 2.6 = 2.5z

0.5 = 2.5z

0.5/2.5 = z

5/25 = z

1/5 = z

0.2 = z

Set {0.2}

-2.1 = 2.5z - 2.6

-2.5z = -2.6 + 2.1

-2.5z = -0.5

z = -0.5 ÷ (-2.5)

z = 0.2

EleoNora [17]
We want to find 9.5% of $50.

First put 9.5% in decimal form. 9.5% = 0.095.

Then multiply 0.095 by 50. 50 * 0.095 = $4.75 fee

The money Kennedy will recieve is going to be 50 dollars minus the $4.75 fee.

50 - 4.75 = $45.25 with the fee subtracted

Which graph represents the polar curve r = 4cos(30)?
stepan [7]

The equation of the polar curve r = 4\cos(3\theta) is an even cosine function.

<h3>Polar curves</h3>

In geometry, polar curves are curves that are represented by the polar coordinates such that they are drawn around a fixed point

The equation of the polar curve is given as:

r = 4\cos(3\theta)

To graph the polar curve, we make use of the following representations:

  • r represents the y-axis
  • \theta represents the x-axis

Using the above representation, we can graph the polar curve

See attachment for the graph that represents r = 4\cos(3\theta)

AURORKA [14]

The percent change would be 36%

<h3>What is percent change?</h3>

Percent increase and percent decrease are measures of percent change, which is the extent to which a variable gains or loses intensity, magnitude, extent, or value.

Given:

4 candy bars = 5$

1 candy bar = 5/4

1 candy bar = 1.25$

Now,

5 candy bars = 4$

1 candy bar =4/5

1 candy bar = 0.8$

% change = (0.8-1.25) / 1.25 *100

                  = 36%
