Answer:

$y^{-2}$

Step-by-step explanation:

there is a rule that says

$(x^a)^b=x^{ab}$

so in our case

$(y^{\frac{-1}{2} })^4=y^{\frac{-4}{2} }=y^{-2}$

so that's our answer

$y^{-2}$

What is the weight, in Newtons, of a person on Earth whose mass is 90 kilograms? Gravity near the Earth's surface is 9.8 m/s2.

valentinak56 [21]

Answer:

W = 882 N

Step-by-step explanation:

Given that,

The weight of a person, W = 90 kg

The value of acceleration due to gravity, g = 9.8 m/s²

We need to find the weight of the person on Earth. The formula for the weight of an object is given by :

W = mg

Substitute all the values,

W = 90 kg × 9.8 m/s²

W = 882 N

So, the weight of the person is equal to 882 N.

Since 1972 the US. inflation rate has averaged 4.8 % per year . Use the approximate doubling time formula to estimate the doubli

Artemon [7]

Answer:

14 3/4 years

Step-by-step explanation:

Let's assume compound inflation. The appropriate formula for that is:

A = P(1 + r)^t.

If we represent current prices by P, then double that would be 2P:

2P = P(1 + 0.048)^t Find t, the time required for prices to double.

Then:

2 = 1.048^t

Taking the natural log of both sides, we get:

ln 2 = t·ln 1.048, so that:

t = (ln 2) / (ln 1.048) = 14.78

At 4.8 inflation, with annual compounding, prices will double in approx. 14 3/4 years.
