Answer: (7)^(^6^x^)=(7)^(^6^x^+^3^)

Step-by-step explanation:

49^3^x=343^2^x^+^1

(7^2)^(^3^x^)=(7^3)^(^2^x^+^1^)

(7)^(^6^x^)=(7)^(^6^x^+^3^)

Up to this points, is the equation in terms of base, from now on, I'm going to try to solve it.

Since we have the same base, exponents must be equal

6x=6x+3\\6x-6x=3\\0=3

Since we lost our variable, there's nothing to solve for. Therefore, this has no solution.

The Eiffel Tower is 324 m tall. If a tourist is looking at it from 100 m away from the base,
romanna [79]

Answer:

80,94º

Step-by-step explanation:

What I've done is, first draw a triangle with a 90º angle and write down the height (324m) and the tourist's distance (100m).

So I calculated the tangent of the angle of the tourist.

The formula is tan=Oposite side/adjacent

tan=\frac{opposite side}{adjacent}

tan=\frac{324}{100} =3.24

And now with your calculator you press "shift" and "tan". Then introduce 3,24 and it will give you the result (80,94º).

I hope it helped.

A skydiver falls 144 feet in 3 seconds. How far does the skydiver fall per second?
Mekhanik [1.2K]
If a skydiver falls 144 feet in 3 seconds in you need to find the time per second that they’re falling, you would simply have to get the time per one second. You have to get the 3 to one, so you would divide by 3 on both sides, getting 48 feet per second. (assuming they fell at the same rate all 3 seconds)
