What is the product written in scientific notation? (1.4 × 103)(2.5 × 10–6) A. 3.9 × 10–3 B. 3.9 × 10–18 C. 3.5 × 10–3 D. 3.5 × 10–2

Answers

Answer 1

Answer: Just multiply as shown below:-

1.4 * 2.5 = 3.5
10^-6 and 10^3 = 10^-6+3 = 10^-3

3.5 * 10^-3

Answer: C. 3.5 × 10–3

Answer 2

Answer: Hi

1.4 × 10³ × 2.5 × 10⁻⁶ = 1.4 × 2.5 × 10³ × 10⁻⁶ = 3.5 × 10⁻³

1.4 × 2.5 = 3.5

10³ × 10⁻⁶ = 10³⁻⁶ = 10⁻³

Answer: C) 3.5 × 10⁻³

If the area of a rectangle is 40" and the perimeter is 48", what are the side lengths of the rectangle?

Figure 2 length 10 width find perimeter and area

Answers

Alrighty man, I'm gonna teach you a math.
If you're looking for perimeter, thats how long the shape is on the outside. To find the perimeter, add your base and your height and multiply it by two. For us, height is 10, and base is 2. 10+2x2= 24.
To find area, you have to multiply the base times the height. 10x2= 20
The area is 20 units squared and the perimeter is 24 units.

find the slope of the line through the given pair of points, if possible. Based on the slope, indicate whether the line through the points rises from left to right, falls from left to right, is horizontal, or is vertical (-7,-9) and (-5,-8)

Answers

easy peasy
slope=(change in rise)/(change in run)
aka
slope between points (x1,y1) and (x2,y2) is
slope=(y2-y1)/(x2-x1) since y is rise/up and x is run/leftright

points

(-7,-9) and (-5,-8)
x1=-7
y1=-9
x2=-5
y2=-8
remember minusing a negative means addin a positive
slope=(-8-(-9))/(-5-(-7))=
(-8+9)/(-5+7)=1/2

slope=1/2

positive slopes go from bottom left to top right

since it is less than 1
it is more horizonal than vertical

What two numbers multiply to 12 and add to 8

Answers

to get the answer, lets first make the factors of 12
1 * 12 = 12
2 * 6 = 12
3 * 4 = 12

Now we can easily get our answer, we know
1 +12 =13 so this is not a correct option.
3 + 4 = 7 this is also not the correct answer.
6 + 2 = 8 this is the correct answer

Hope this helped you.. :)

Your answer would be 6 and 2.
Six times two equals 12, and when 6 is added to 2, it equals 8.
