Find the area of the triangle given: B = 3b^2 H = 12p^7b^19

Bogdan [553]

Step-by-step explanation:

$\frac{3 {b}^{2} \times 12 {p}^{7} {b}^{19} }{2} = \frac{3 {b}^{21} \times 12 {p}^{7} }{2} = \\ = 3 {b}^{21} \times 6{p}^{7} = \\ = 18 {b}^{21} \times {p}^{7}$

How many arrangements of 3 digits can be formed from the digits 0 through 9?

nalin [4]

Answer: The required number of arrangements is 1000.

Step-by-step explanation: We are given to find the number of arrangements of 3 digits that can be formed from the digits 0 to 9.

Since we are talking about the 3 digit arrangements, not the 3 digit numbers,

so we have 10 options 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 for each of the three places in the arrangement.

Therefore, the number of 3 digit arrangements that can be formed is given by

$n=10\times 10\times 10=1000.$

Thus, the required number of arrangements is 1000.

Work out the length of CD Answer to 3 significant figures

vladimir1956 [14]

Answer:

Step-by-step explanation:

I can be wrong but i most likely sure it is correct because a triangle is 180 degrees you have to add 102 with 52 take that total and subtract it with 180 to find that angle is what you need to find the length. Again i am not sure but might be right.

What type of quadrilateral is created by the points: L (-5,4), M (2,2), N (0,-3), S (-7,-1)

kumpel [21]

Given same lengths and slopes of the opposite sides and nature of the angle between adjacent sides, we have;

The type of quadrilateral is a parallelogram

<h3>How can the type of quadrilateral be found?</h3>

The given points are;

L(-5, 4), M(2, 2), N(0, -3), S(-7, -1)

Lengths of the sides are;

Length of LM = √((2-(-5))²+(2-4)²) ≈ √(53)

Length of MN = √((2-0)²+(2-(-3))²) ≈ √(29)

Length of NS = √((0-(-7))²+((-3)-(-1))²) ≈ √(53)

Length of LS = √(((-7)-(-5))²+((-1)-4)²) ≈ √(29)

Therefore;

The lengths of opposite sides are the same.

Slope of LM = (2-4)/(2-(-5)) = -2/7

Slope of MN = (2-(-3))/(0-2) = 5/2

Slope of NS = ((-3)-(-1))/(0-(-7)) = -2/7

Slope of LS = ((-1)-4)/(-7-(-5)) = 5/2

Therefore;

The opposite sides are parallel, and

The the adjacent sides are not perpendicular

The quadrilateral created by the points L(-5, 4), M(2, 2), N(0, -3), S(-7, -1) is therefore;

A parallelogram
