Answer:
pd = 6
Step-by-step explanation:
p ∝ 1/d
change ∝ to = by adding constant k or c
p = k * 1/d
p = k/d
Cross multiply
pd = k
k = pd
k = 2 * 3
k = 6
From pd = k
pd = 6
Answer:
2.79 * 10^4
Step-by-step explanation:
6.4 x 10^3+ 1.4 x 10^4+ 7.5 x 10^3
The exponents need to be the same
6.4 x 10^3+ 14 x 10^3+ 7.5 x 10^3
Add the numbers
6.4 + 14+ 7.5 =27.9
Multiply by the exponent
27.9 * 10 ^3
But this is not in scientific notation
Move the decimal one place to the left and add one to the exponent
2.79 * 10^4
The area of a rhombus can be found by using the formula:
A = (1/2)(d1)(d2)
Area = (1/2)(8)(6)
Area = 24 cm^2
Your other option is to remember that in a rhombus the diagonals bisect each other, and form right triangles. So you have 4 right triangles each with sides of 4 cm (1/2 of 8 cm) and 3 cm (1/2 of 6 cm). 4 x [(1/2) x (4)(3)] = 4 x 6 = 24 cm^2.
Answer:
-3
Step-by-step explanation:
This is slope-intercept form y = mx + b where m is slope and b is y-intercept.
You just read the numbers knowing what they represent, and in this case b is -3.
