alex used the data to make the graph below. how could it be misleading? how could you redraw it to be less misleading?
Maru [420]
The graph is misleading because it does not start out at 0 inches of rainfall. 
To make it accurate, you'd redraw it and start with 0 inches of rainfall and go up from there.

Through: (3, -5) and (0, -2) <br><br><br>please add the steps please.​
Vlad [161]
1: -5 = 3m + c
2: -2 = 0 + c

From equation 2, we knew c = -2
So we sub into equation 1 and got the value of m

-5 = 3m - 2
m = -1

The equation of line is y = -x - 2

Answer:

Q3: x1=2+i, x2=2-i Q4: x1=-3/2+i, x2=-3/2-i

Step-by-step explanation:

x^{2} - 4x + 5 =0

( 4± \sqrt{16 - 4*1*5} ) / 2 = (

x1= 2+i

x2= 2-i

2x^{2} +6x + 5 =0

( -6 ± \sqrt{36 - 4*2*5} ) / 4 = (-6 ± \sqrt{-4} )/4= (-3 ± i)/2

x1 = -3/2 +i

x2 = -3/2 -i

The graph of the derivative of a function f crosses the x-axis 3 times. What does this tell you about the graph of f ?
expeople1 [14]

Answer:

D. The function f has 3 horizontal tangent lines

Step-by-step explanation:

Well whenever any function crosses the x-axis, it means that the y-value is equal to zero.

In this case when the derivative passes the x-axis it indicates the tangent line corresponding to that x-value has a slope of zero, which when plotted is a horizontal line.

This means that the graph f has 3 horizontal tangent lines.
