namely, how many times does 4 x 10⁻³ go into 8 x 10⁶.


\bf ~~~~~~~~~~~~\textit{negative exponents}\\\\a^{-n} \implies \cfrac{1}{a^n}\qquad \qquad\cfrac{1}{a^n}\implies a^{-n}\qquad \qquad a^n\implies \cfrac{1}{a^{-n}}\\\\-------------------------------\\\\\cfrac{\stackrel{elephant}{8\times 10^6}}{\stackrel{ant}{4\times 10^{-3}}}\implies \cfrac{8}{4}\times \cfrac{10^6}{10^{-3}}\implies 2\times 10^6\cdot 10^3\\\\\\2\times 10^{6+3}\implies 2.0\times 10^9

(6,-3) and (x,-29); slope=-3
Sidana [21]

Answer:

x=44/3

Step-by-step explanation:


slope = (y2-y1)/(x2-x1)

substitute what we know

-3 = (-29--3)/(x-6)

simplify

-3 =(-29+3)/(x-6)

multiply each side by (x-6)

-3(x-6) = (-29+3)/(x-6) * (x-6)

the (x-6)'s on the right cancel

-3(x-6) = (-29+3)

distribute

-3x*-3*-6 = -29+3

-3x+18 = -26

subtract 18 from each side

-3x = -44

divide by -3

x = -44/-3

x=44/3

2.6 1.8 4.2 3.3 how do i estimate these decimals
Masja [62]
Hello!

If the digit to the right is less than 5, you drop it to the left one. If the digit is greater than 5, then you round it to the next decimal. So, here are the answers:

2.6 rounded = 3

1.8 rounded = 2

4.2 rounded = 4

3.3 rounded = 3

A rectangle has a length of x and a width of 5x^3+4-x^2. What is the polynomial that models the perimeter of the rectangle
sveticcg [70]

Answer:

L= x

And the width for this case is:

W= 5x^3 +4 -x^2

And we know that the perimeter is given by:

P= 2L +2W

And replacing we got:

P(x) = 2x +2(5x^3 +4 -x^2)= 2x +10x^3 +8 -2x^2

And symplifying we got:

P(x)= 10x^3 -2x^2 +2x+8

Step-by-step explanation:

For this problem we know that the lenght of the rectangle is given by:

L= x

And the width for this case is:

W= 5x^3 +4 -x^2

And we know that the perimeter is given by:

P= 2L +2W

And replacing we got:
