Answer:

  1.60×10^-12 m^2

Step-by-step explanation:

The prefix μ stands for "micro-", which means 10^-6. So, 1 micro-meter is ...

  1 μm = 10^-6 m

A square micrometer is then ...

  (1 μm)^2 = (10^-6 m)^2 = 10^-12 m^2

1.6 of them is ...

  1.6 μm^2 = 1.6×10^-12 m^2

Which equation represents a line that passes through (4, 1/3,) and has a slope of 3/4 ?
Aleks [24]

Answer:

second option

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = \frac{3}{4} and (a, b) = (4, \frac{1}{3} ) , thus

y - \frac{1}{3} = \frac{3}{4}(x - 4)

The base and height of a triangle with base 12 in and the height 6 in are both tripled
Marysya12 [62]

Answer:

Base=36

Height=18

Step-by-step explanation:

To work this out you would first multiply 12 by 3, which gives you 36. Then you would multiply 6 by 3, which gives you 18.

1) Multiply 12 by 3.

12*3=36

2) Multiply 6 by 3.

6*3=18

3) Base=36

Height=18

What is the slope of the line segment with endpoints at (2,-5)<br> and (-1, -1)?
Advocard [28]

Answer:

The slope of the line segment is m=-\frac{4}{3}

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have the points

(2,-5)  and (-1, -1)

substitute in the formula

m=\frac{-1+5}{-1-2}

m=\frac{4}{-3}

m=-\frac{4}{3}
