2,000.h for h = 0.004<br> 2,000 h =

Gekata [30.6K]

Answer:

$h=2\times 10^6$

Step-by-step explanation:

We need to find h for the following condition.

2,000×h = 0.004

Dividing both sides by 2000

$\dfrac{2000h}{2000}=\dfrac{0.004}{2000}\\\\h=0.000002\\\\h=2\times 10^6$

So, the value of h is equal to $2\times 10^6$ .

HELP!!! Show work!!!!!!

Misha Larkins [42]

A) x^5/6 ≠ 5√6, Because 5 is in numerator & 6 in denominator in exponential expression so it can be in direct expression.

It is False.

b) (16)^1/4 = 2.
It is False

c) a^2/7 + a^4/7 = a^2/7+4/7 = a^6/7
It is False.

d) Here, powers are not equivalent.
Again, It is False

e) (27x^6)^2/3 = 27^2/3 x^12/3
= 9x^4
It is True.

13) Here, expression would be: a^2/3
In short, Your Answer is Option B

14) ∛8x^6
= ∛8 x^6/3
= 2x²
In short, Your Answer would be Option C

Hope this helps!

I don’t know how to use the triangle area to calculate the area of the inscribed polygons

Trava [24]

First of all, let's recall the area of a triangle, knowing its base (b) and height (h):

$A = \cfrac{bh}{2}$

The exercise is showing you that, if you inscribe a polynomial with more and more side, the area of the polynomial will approximate the area of the circle better and better (you can see youself that the polygon is "filling" the circle more and more as the number of sides increase).

Now, the second column tells you the area of each of the triangles the polygon is split into. So, we can see that the first polygon is split into 3 triangles, each of them having base 1.73 and height 0.5.

So, the area of each triangle is

$A = \cfrac{1.73 \cdot 0.5}{2} = 0.4325$

There are three of these triangles, so the area of the whole polygon is

$A = 0.4325 \cdot 3 = 1.2975$

In the second case, you have six triangles, each with base 1 and height 0.87. So, the whole area is

$A = 6 \cdot \cfrac{1\cdot 0.87}{2} = 0.87 \cdot 3 = 2.61$

Finally, in the last case you have 8 triangles, each with base 0.77 and height 0.92. So, the whole area is

$A = 8 \cdot \cfrac{0.77\cdot 0.92}{2} = 0.77\cdot 0.92 \cdot 4 = 2.8336$

Mr. and Mrs. McClurrie are debating on whether or not to remove a tall tree in their front yard. Mr. McClurrie is concerned that

hichkok12 [17]

Tanα=y/x

y=xtanα, we are told that x=25ft and α=30°

y=25tan30° ft

y≈14.43 ft (to nearest hundredth of a foot)

Since their home is 20 feet from the base of the tree, it poses no risk right now.
