Answer:

So let's take two ratios
6×x=9
6/9=x
2/3=x

I will give u brianliest

Bond [772]

Answer:

1: $3$ × $2$

2: $y^6$

Step-by-step explanation:

1:

Multiply the numbers: $y(^3^*^2)$

$3*2 = 6$

Write it without exponents:

$y * y * y * y *y *y$ so $6y$ .

2:

$(y^3)^2$

Apply exponent rule : $(a^b)^c=a^b^c,$ assuming $a\geq 0$

$(y^3)^2=y^3^*^2$

$=y^3^*^2$

Multiply the numbers: $3 * 2 = 6$

$= y^6$

Hope I helped! If so, may I get Brainliest and a Thanks?

Thank you, have a good one! =)

The magnitude of vector a = (5,m) is 13 and the magnitude of vector b = (n, 24) is 25. What are m and n

Ulleksa [173]

Answer:

$m=12\,,n=7$

Step-by-step explanation:

The magnitude of vector $(x,y)$ is given by $\sqrt{x^2+y^2}$

The magnitude of vector $a=(5,m)$ is $13$ .

$\sqrt{5^2+m^2}=13\\5^2+m^2=13^2\\25+m^2=169\\m^2=169-25\\m^2=144\\m=12$

The magnitude of vector $b=(n,24)$ is $25$ .

$\sqrt{n^2+24^2}=25\\n^2+24^2=25^2\\n^2+576=625\\n^2=625-576\\n^2=49\\n=7$

Therefore,

$m=12\,,n=7$

"Suppose the leftmost digits of 2 numbers are 8 and 3. Can you tell which number is greater? Explain."

Mariulka [41]

No, without further information you can't tell which number is greater. This is because there could be any amount of other digits to the right, which changes the value of the leftmost digit depending on the number it is a part of. Hope this helps! :)
