Solve x3 = 125 over 27. 25 over 9 ą25 over 9 5 over 3 ą5 over 3

1 answer:

3 0

<span>x^3 = 125/27

Real solution:
x = (125/27)^(1/3) = 5/3

NOTE: -5/3 is not a solution, because
(-5/3)^3 = (-5/3) * (-5/3) * (-5/3) = -125/27</span>

To measure the height of a tree, a surveyor walked a short distance from the tree and found the angle of elevation was 43.9°, th

padilas [110]

Answer:

The height of the tree is H = 77.06 m

Step-by-step explanation:

From Δ ABC

AB = height of the tree

$\tan 43.9 = \frac{AB}{BC}$

$\tan 43.9 = \frac{h}{x}$

h = 0.9623 x ------- (1)

From Δ ABD

$\tan 37.6 = \frac{h}{20+ x}$

h = 0.77 (x + 20) ----- (2)

Equating Equation 1 & 2 we get

0.9623 x = 0.77 (x + 20)

0.9623 x = 0.77 x + 15.4

x (0.1923) = 15.4

x = 80.08 m

Thus the height of the tree is given by

H = 0.9623 x

H = 0.9623 × 80.08

H = 77.06 m

Therefore the height of the tree is H = 77.06 m

Answer: Choice [D] - "power of a power" ✅

Step-by-step explanation:

Hii, do you need to know which law you should use to simplify $\sf\bigg(x^4\bigg)^9$ ?

No problem!

The law we will use here is "power of a power".

What "power of powers" means is we raise a power to a power, which is exactly what we do here: We raise x^4 to the power of 9. To simplify our expression, we multiply the powers. ( $\boldsymbol{4\cdot9}$ )

So the right answer is: Choice [D] - "Power of a power"

The simplified answer is $\LARGE\boldsymbol{x^{4\cdot9}=x^{36}}$

Voila! There's our answer, cheers!

Hope that this helped! Best wishes.

Find the area of the figure.

gayaneshka [121]

Answer:

33 units squared is the area of the shape.

Step-by-step explanation:

We know that the the area of the orange (bookmark) shape would be 42 units squared total, since the length is 7 and width is 6 (or vice versa) Now, all we need to find is how many squares inside the rest of the small portion to fill in the shape and subtract that from 42. Adding the squares and half squares in the small portion, I got 9. 42-9 is 33 units squared

How are mountains and plateaus alike?

IgorLugansk [536]

Answer:

It is similar to a mountain in that it is dramatically higher than what is immediately around it. But mountains usually have a distinct apex or peak that is very small relative to the base and not typically level. Plateaus and mesas have tops only a little smaller than the base, and relatively flat. If the aspect ratio is less than 1, plateau. If greater than 1, mesa.
