Answer: All x-coordinates are different, so this relation is a function.

Having the same y value more than once is not a problem for a function.

"This (does not/does) represents a function because different (x values/y values) can have the same (x values/y values)."

What is the value of (3/10)3

Elenna [48]

Answer:

$\frac{9}{10}$

Step-by-step explanation:

In this question, one is asked to multiply a fraction by a whole number, first model the question.

$\frac{3}{10}(3)$

In a situation like this, one multiplies the whole number by the numerator (number) over the fraction.

$\frac{3*3}{10}$

Simplify,

$\frac{9}{10}$

A common error that people make is that they will multiply both the numerator and denominator by the whole number, this is the same as multiplying the answer by (1), thus it is incorrect.

Identify the ordered pair that represents the vector from A(-8,-1) to B(-5,3) and the magnitude of vector AB.

wel

In order to find the vector that points from A to B we need to subtract each component of A from the corresponding component of B, according to the formula: v(a→b)=(b1−a1,b2−a2) In this case we have : v(a→b)=(−5−(−8),3−(−1)) <span>v(a→b)=(3,4)

</span>To find the magnitude we use the formula: ||v|= √(v1^2)+(v1^2)

So:
||v|= √(32)+(42) ||v|= √9+16 ||v|= <span>√</span>25 ||v|= 5
