We know that
the distance formula is
d=√[(y2-y1)²+(x2-x1)²]
point (0,0) and point <span>(–2, –4)
</span>d=√[(-4-0)²+(-2-0)²]---------> d=√[16+4]-------> d=√20
d=4.47 units

the answer is the option B
see the attached figure

How do I answer this question

soldi70 [24.7K]

The answer is C. 2.

This is because the part that is inside of the parentheses is equal to 4. Multiplying the fractions in the numerator is equal to $4^\frac{3}{2}$ .

$\frac{4^\frac{3}{2}}{4^\frac{1}{2}}=4.$ , using the exponential rule 3/2-1/2=2/2 or 1. 4^1=4.

Now, we reduced the fraction, so all that is left is $(4)^\frac{1}{2}$ . This is equal to 2.

So your answer is 2.

I hope this helps :)

Find the values of x and y.

Harrizon [31]

4x+5x = 90
9x = 90
x = 10

10y + 10 + 5x = 180
10y + 10 +5(10) = 180
10y + 60 = 180
10y = 120
y = 12

answer
<span>d) x = 10, y = 12</span>

Victor has 861 marbles he’s putting into bags with twenty five in each bag. How many marbles will have in the bag that isn’t ful

Rashid [163]

11 since you’d divide 861 by 25, but you’d still not get a whole number so you’d get that as a remainder. then you’d divide .44 by 25 and get 11, cause there was 25 marbles in each bag.
