Answer:

$4 \sqrt{2}$

Step-by-step explanation:

Rewrite 32 as the product of 16 and 2:

$\implies \sqrt{32}=\sqrt{16 \cdot 2$

Apply exponent rule $\sqrt{a \cdot b}=\sqrt{a}\sqrt{b}$

$\implies \sqrt{16 \cdot 2}=\sqrt{16}\sqrt{2}$

Rewrite 16 as 4²:

$\implies \sqrt{16}\sqrt{2}=\sqrt{4^2}\sqrt{2}$

Apply exponent rule $\sqrt{a^2}=a$

$\implies \sqrt{4^2}\sqrt{2}=4 \sqrt{2}$

Divide the number 480 in a ratio of 3:5

Schach [20]

If it is a ratio of 3:5 you are dividing 480 into 8 parts (3+5).

So divide 480 by 8: 480/8 = 60

Then the ratio is (3x60):(5x60) or 180:300

To check it is correct, add up the two parts to see that they come to 480:

180+300 = 480. All good.

Hope this helps

What is the slope of the line that passes through the points (4, 9) and (1, 6)?

Aleksandr [31]

a = ( 1 , 6 )

b = ( 4 , 9 )

$slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\$

Now just need to put the coordinates in the above equation :

$slope = \frac{9 - 6}{4 - 1} \\$

$slope = \frac{3}{3} \\$

$slope = 1$

And we're done...♥️♥️♥️♥️♥️
