4 0

Answer:

I would tell you the exact coordinates, but since I do not know the coordinates, the best I can say is

Step-by-step explanation:

multiply the coordinates of E by two, and then yoy should get the dilation.

Let C, S and H be the diameters of cell, sand and hair


Diameter of a cell: C=1 \cdot 10^{-5}m

Diameter of a grain of sand: S=2 \cdot10^{-4}m

Part A:

H=0.000025=2.5 \cdot 10^{-5} meters, because it takes 5 movements right of the decimal dot, until there is only one digit to its left.

Part B:

we are comparing S=2 \cdot10^{-4} m to C=1 \cdot10^{-5} m ,

\frac{S}{C}= \frac{2 \cdot 10^{-4}}{1 \cdot 10^{-5}}=\frac{20 \cdot 10^{-5}}{1 \cdot 10^{-5}}=20

thus S is 20 times larger than C

Part C

1m=1 \cdot10^9nm

thus,

H=2.5 \cdot 10^{-5}m=2.5 \cdot 10^{-5} \cdot 1 \cdot 10^9nm=2.5 \cdot 10^{-5+9}=2.5\cdot10^4nm

Part D.

1m=1\cdot 10^9nm\\\\1nm=\displaystyle{ \frac{1m}{10^9}=1\cdot 10^{-9}m}

thus 300 nm are written in meters as follows:

300nm= 300\cdot 1\cdot 10^{-9}m=3\cdot 10^2 \cdot 10^{-9}m=3\cdot 10^{-7}m

The distance between two points is 6_/6.One endpoint is (4,-1). It is known that the y-coordinate of the other endpoint is 9.
babunello [35]

The x-coordinate of the given endpoint will be "x = 4 \pm 2\sqrt{29}".

According to the question,

The end points are:

  • (x_1,y_1) = (4,-1)
  • (x_2, y_2) = (x,9)

Distance,

  • 6\sqrt{6}

As we know,

The distance formula,

→ Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

By substituting the values, we get

→         6\sqrt{6} = \sqrt{(x-4)^2+(9+1)^2}

→          216= (x-4)^2+100

→   (x-4)^2 = 116

→       x-4 = \pm \sqrt{116}

→       x-4=\pm 2\sqrt{29}

→             x = 4 \pm 2\sqrt{29}                

Thus the above answer is right.
