(2.3 x 105)(1.5 x 104) in scientific notation plssss ASAP

zhenek [66]

By using scientific notation we calculated (2.3 $\times$ 10⁵)(1.5 $\times$ 10⁴) we got 345 $\times$ 10⁷.

Given that,

(2.3 $\times$ 10⁵)(1.5 $\times$ 10⁴)

By using scientific notation

The scientific notation allows us to express extremely large or extremely small numbers by multiplying them by single-digit integers and by 10 raised to the power of the corresponding exponent. The exponent is either positive or negative depending on how big or little the number is.

Now, we calculate

(2.3 $\times$ 10⁵)=2.5 $\times$ 100000=230000

(1.5 $\times$ 10⁴)=1.5 $\times$ 10000=15000

Now,

=230000 $\times$ 15000

=3450000000

=345 $\times$ 10⁷

Therefore, By using scientific notation we calculated (2.3 $\times$ 10⁵)(1.5 $\times$ 10⁴) we got 345 $\times$ 10⁷.

Find the Y-coordinate of point P that lies 1/3 along segment RS, where R (-7, -2) and S (2, 4).

QveST [7]

Solution:

Given that the point P lies 1/3 along the segment RS as shown below:

To find the y coordinate of the point P, since the point P lies on 1/3 along the segment RS, we have

$\begin{gathered} RP:PS \\ \Rightarrow\frac{1}{3}:\frac{2}{3} \\ thus,\text{ we have} \\ 1:2 \end{gathered}$

Using the section formula expressed as

$[\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n}]$

In this case,

$\begin{gathered} m=1 \\ n=2 \end{gathered}$

where

$\begin{gathered} x_1=-7 \\ y_1=-2 \\ x_2=2 \\ y_2=4 \end{gathered}$

Thus, by substitution, we have

$\begin{gathered} [\frac{1(2)+2(-7)}{1+2},\frac{1(4)+2(-2)}{1+2}] \\ \Rightarrow[\frac{2-14}{3},\frac{4-4}{3}] \\ =[-4,\text{ 0\rbrack} \end{gathered}$

Hence, the y-coordinate of the point P is
