Answer:

$d = \sqrt{(x2 - x1) {}^{2} + (y2 - y1) {}^{2} }$

Step-by-step explanation:

$d = \sqrt{( - 4 + 3) {}^{2} + (7 - 9) {}^{2} }$

$d = \sqrt{(1 + 4)} = \sqrt{5}$

Factor 75t2 + 12.<br> 3(5t + 2)2<br> 3(25+2 +4)<br> 3(251-4)

frosja888 [35]

Answer:

$75t^2+12=3(25t^2+4)$

Option C)

Step-by-step explanation:

Here we are given with the expression $75t^2+12$

The GCF of $75t^2$ and 12 is 3

Hence we take 3 as GCF and bring it in front of the bracket.

$3(25t^2+4)$

It can not be factorise furthure as there is no GCF of 25 and also there is no rule for sum of squares so that we may apply it on this. Hence the answer would be

$3(25t^2+4)$

Option C)

Anna is draining water out of a 50 gallon rain barrel. The graph shows the relationship between time in minutes and the gallons

tatiyna

Answer:

6 < x ≤ 20

Step-by-step explanation:

First, let's use the points (0, 50) and (20, 0) to find the equation of the line.

m = Δy / Δx

m = (0 − 50) / (20 − 0)

m = -2.5

y = -2.5x + 50

Now find the time when y = 35.

35 = -2.5x + 50

-15 = -2.5x

x = 6

So there is less than 35 gallons in the barrel when 6 < x ≤ 20.
