Answer:

6 pairs of socks for 6.99.

Step-by-step explanation:

Because 11.99 is almost $12 and 6.99 is almost $7, so 6 for 7 is better than 10 for 12. Also if you divide 11.99 by 10 you get 1.199 and if you divide 6.99 by 6 you get 1.165.

(2^8 * 3^-5 * 6^0)^-2 * (3^-2/ 2^3) ^4 * 2^28

11Alexandr11 [23.1K]

$\left(2^8\cdot \:3^{-5}\cdot \:1\right)^{-2}=\left(1\cdot \frac{256}{243}\right)^{-2}=\left(\frac{256}{243}\right)^{-2}=\left(\frac{243}{256}\right)^2$

$\left(2^8\cdot \:3^{-5}\cdot \:6^0\right)^{-2}\left(\frac{3^{-2}}{2^3}\right)^4\cdot \:2^{28}$

$=2^{28}\left(\frac{3^{-2}}{2^3}\right)^4\left(3^{-5}\cdot \:2^8\cdot \:1\right)^{-2}$

Consider

$\left(2^8\cdot \:3^{-5}\cdot \:1\right)^{-2}=\left(1\cdot \frac{256}{243}\right)^{-2}=\left(\frac{243}{256}\right)^2=\frac{243^2}{256^2}$

$=2^{28}\left(\frac{3^{-2}}{2^3}\right)^4\frac{243^2}{256^2}$

$=2^{28}\cdot \frac{1}{2^{12}\cdot \:3^8}\cdot \frac{243^2}{256^2}$

$=\frac{243^2\cdot \:1\cdot \:2^{28}}{256^2\cdot \:3^8\cdot \:2^{12}}$

$=\frac{2^{16}\cdot \:243^2}{3^8\cdot \:256^2}$

$=\frac{2^{16}\cdot \:3^{10}}{2^{16}\cdot \:3^8}$

$=3^2$

$=9$

Let f(x)= 2x2−3x+8 What is the value of f(-4)?

Ne4ueva [31]

Answer:

52

Step-by-step explanation:

So we have the function:

$f(x)=2x^2-3x+8\\$

And we want to find f(-4).

To find f(-4), substitute -4 for x. Thus:

$f(-4)=2(-4)^2-3(-4)+8$

Square:

$f(-4)=2(16)-3(-4)+8$

Multiply:

$f(-4)=32+12+8$

Add:

$f(-4)=44+8$

Add:

$f(-4)=52$

And we're done!

Our answer is 52.

Answer:

49 = 0 +9.8t
t = 5

Step-by-step explanation:

It usually works to follow directions.

a) Substitute the numbers into the formula:

v = u + at

49 = 0 +9.8t

b) Solve the equation:

49/9.8 = t = 5 . . . . . divide by the coefficient of t
