Please help with geometric mean!!

Mathematics
1 answer:
aleksandr82 [10.1K]3 years ago
8 0

The exact value of y is 4\sqrt{3}.

Solution:

The attached below shows how the formula is written.

Using geometric mean,

Total base length (p + q) = 8

q = 6

p = 8 – 6 = 2

Let us first find the height of the triangle.

h^2=pq

h^2=2\times6

h^2=12

Taking square root on both sides,

h=\sqrt{12}

Using Pythagoras theorem,

<em>In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.</em>

y^2=(\sqrt{12})^2+6^2

y^2=12+36

y^2=48

y=4\sqrt{3}

The exact value of y is 4\sqrt{3}.

HELP! last one of the day!

The bisector of the angle at A (call it AQ) divides the segment BC into segments BQ:QC having the ratio AB:AC. Use this fact to find x.

.. 9:15 = (2x -1):3x
.. 15(2x -1) = 9*3x . . . . . the product of the means equals the product of extremes
.. 30x -15 = 27x
.. 3x = 15
.. x = 5

___
According to the value of x, the bisector AQ divides the triangle into two isosceles triangles: ABQ, ACQ.

Are -3.9 and -0.99 on the same side or the opposite side of zero ?
MAXImum [283]

Same side.  Locate -3.9 on the number line.  Then -0.99 is to the right of -3.9, with both numbers being on the same side (that is, on the left side) of zero.

Find the gradients of line a and b
34kurt

Answer:

3 and - 4

Step-by-step explanation:

Calculate the gradients using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

Line A

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (1, 1) ← 2 points on the line

m = \frac{1+2}{1-0} = 3

Line B

with (x₁, y₁ ) = (1, 1) and (x₂, y₂ ) = (0, 5) ← 2 points on the line

m = \frac{5-1}{0-1} = \frac{4}{-1} = - 4
