Hernan cuts a board that is 7/10 of a meter long After the cut the board is 3/10 of a meter long how long is the piece that he c

Darina [25.2K]

Given that original lenght of the board before cut $= \frac{7}{10}$ meter

Lenght of the board that is left after cutting from the original piece by Hernan $= \frac{3}{10}$ meter

Now we have to find the lenght of the piece which is cut.

To find that we just need to subtract smaller piece from larger piece

Required Length $= \frac{7}{10}-\frac{3}{10}$ meter

Required Length $= \frac{7-3}{10}$ meter

Required Length $= \frac{4}{10}$ meter

reduce the fraction

Required Length $= \frac{2}{5}$ meter

Hence final answer is $\frac{2}{5}$ meter.

What is - 4i ^ 19, simplify

german

Answer:

$"i"$

Step-by-step explanation:

$i =\sqrt{-1} \\i^{2}= -1\\\\i^{3}= -i\\\\i^{4}= 1\\\\i^{5}= i\\$

the cycle repeats every 4

19/4 = 4.75

16 is divisible by 4 plus three more

thus $i^{19} = -i$ but you problem has a minus in front so "i"

Graph this function

galben [10]

Solve the equation to get values for x and y.

For example,

When x is 0,

y = 1

You have one point on the line (0,1)

Now, when y = 0,

x = 36/5 = 7.2

You have one more point on the line (7.2,0)

Plot these points on the x and y axes.

Draw a straight line joining these two points. ( I hope you can plot the points)
