Answer:

170

Step-by-step explanation:

168.9 is between 160 and 170 ← both to 2 significant figures.

However 168.9 is nearer to 170 than 160, hence

168.9 ≈ 170 ( to 2 significant figures )

Write an equation of the line that passes through the point (8, -1) and is perpendicular to the line pictured.
True [87]

Answer:

y = -1/4x+1

Step-by-step explanation:

First we need to find the slope of the line pictured

(1,4) and (0,0)

m = (y2-y1)/(x2-x1)

   = (0-4)/(0-1)

   = -4/-1

   =4

The perpendicular line has a slope that is the negative reciprocal

-1 /(4)

-1/4

We have a point and a line

y = mx+b  where m is the slope and b is  the y intercept

y = -1/4x +b

-1 = -1/4(8) +b

-1 = -2+b

Add 2 to each side

b = 1

y = -1/4x+1

A colony of 85 bacteria doubles in size every 126 minutes. What will the population be 378
SVETLANKA909090 [29]

Answer:

680 Bacteria

Step-by-step explanation:

378 is evenly divisible by 126, which is equal to 3.

The first 126 minutes, the 85 bacteria will double to 170 bacteria.

The second 126 minutes (252 minutes total), the 170 bacteria will double to 340 bacteria.

The final 126 minutes (378 minutes total), the 340 bacteria will double to 680 bacteria total.

If this helped, a brainliest would be greatly appreciated!
