Answer:

Step-by-step explanation:

m = $\frac{y_{2} - y_{1} }{x_{2} -x_{1} }$

(- 2, - 10)

(4 , - 4)

m = $\frac{-4+10}{4+2}$ = 1

y + 4 = (x - 4) ⇒ <em>y = (x - 4) - 4</em>

Answer:

0.5 m³

Step-by-step explanation:

Volume is the combination of 2 volumes

1. Dimensions: 0.5 m, 05 m and 1.5 - 1 = 0.5 m
2. Dimensions: 1 m, 0.5 m and 0.75 m

So the volume is:

0.5*0.5*0.5 + 1*0.5*0.75 = 0.5 m³

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:

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