Which line is parallel to y= -52 + 6 and passes through (4, -2)?
Alexxandr [17]

Answer:

\[y=-5x+18\]

Step-by-step explanation:

Given that the line is parallel to \[y = -5x + 6\]

Hence the slope of the line is given by -5

Hence the equation of the required line can be represented by \[y = -5x + c\]

This line passes through (4,-2). Substituting:

\[-2 = -5 * 4 + c\]

=> \[-2 = -20 + c\]

=> c = 20-2 = 18

So the required equation of the line is given by : \[y = -5x + 18\]

From the given options, option 3 is the correct one.

In the right triangle below, tanA = 0.45. What is the approximate length of AB?
kodGreya [7K]

Answer with Step-by-step explanation:

We are given that:

tanA = 0.45

tanA= \dfrac{Perpendicular}{Base}

      =  \dfrac{BC}{AC}

⇒  \dfrac{BC}{AC}=0.45

⇒  \dfrac{9}{AC}=\dfrac{45}{100}

⇒  \dfrac{9}{AC}=\dfrac{9}{20}

⇒  AC= 20

Hence, by pythagoras theorem

AB²=AC²+BC²

AB²=20²+9²

AB²=481

⇒  AB=21.9 units

Hence,  the approximate length of AB is:

22 units

Zina [86]

Answer:

1.6

Step-by-step explanation:

The average of this ten number is (1+6+2+4+4+3+5+5+2+8)/10=4

So the MAD is (|1-4|+|6-4|+|2-4|+|4-4|+|4-4|+|3-4|+|5-4|+|5-4|+|2-4|+|8-4|)/10

=(3+2+2+0+0+1+1+1+2+4)/10

=1.6
