sum is angles of a Pentagon=540°

x°+138°+2x°+80°+112°=540°

3x°+330°=540°

3x°=540°-330°

3x°=210°

3x°/3°=210°/3°

x=70

Which graph would help you find the solutions of 2 – x2 = –x?
Lelechka [254]

Step-by-step explanation:

A quadratic graph will surely help you find the solutions

X2-x-2=0

x1=2 x2= -1

Substitute each of the x value in the original equation to get the y value

(2)^2-(2)-2= 0 (2,0)

(-1)^2-(-1)-2=-2 (-1,-2)

plot the coordinates on the graph,the graph should be a curve

Answer: The mean is 3780

Step-by-step explanation:

Mean is found by adding all values and dividing the sum by how many values were added.

4250+4019+3895+3739+3401+3376=22680
22680/6=3780

The graph shows the data points in the table and the exponential regression model associated with the data ?
Ipatiy [6.2K]
From the graph, it is obvious that the trend is decreasing from 100 on day 2, to 1 on day 10. So, the answer could either be A or C. The question would be how fast is it decreasing? To illustrate this, let's find the difference of consecutive data:

100 - 26 = 74
26 - 6 = 20
6 - 2=4
2-1=1

It must not be an additive rate because there is no common difference. Let's illustrate if the trend is in multiplicative rate:

100/26 = 3.85
26/6 = 4.33
6/2 = 3
2/1 = 2

More or less, they have a common divider. Hence, the decreasing rate is in multiplicative rate. The answer is A.
