Answer:  The 2/9 should have been simplified to 2/3. Then multiply 1/7 and 2/3 to find the product, 2/21

You have to "simplify" both factors at the same time before moving on to multiplying them.

Step-by-step explanation:

Another way to do this is to multiply straight across 3/7 × 2/9 to get  6/63 then notice that the numerator and denominator are both multiples of 3.

Simplify by dividing numerator and denominator by 3 to get 2/21

Simplify the product.
liberstina [14]

The value of the product expression is –6p^3 + 8p^2 – 10p

<h3>How to simplify the product?</h3>

The product expression is given as:

2p(–3p2 + 4p – 5)

Rewrite properly as:

2p(–3p^2 + 4p – 5)

Remove the bracket

2p * –3p^2 + 2p * 4p – 2p * 5

Evaluate the products

–6p^3 + 8p^2 – 10p

Hence, the value of the product expression is –6p^3 + 8p^2 – 10p

The radioactive substance polonium-210, with a half-life of 138.39 days, is present in tobacco. Suppose that the soot in an ex-s
Ksju [112]

Answer:

16.07 milligrams

Step-by-step explanation:

From the question,

Using the formula of radioactive decay,

R/R' = 2ᵃ/ᵇ..................... Equation 1

Where R = Original mass of the polonium-210, R' = Final mass of polonium-210 after decaying, a = Total disintegration time, b = half life of polonium-210.

Make R' the subject of the equation

R' = R/(2ᵃ/ᵇ)................ Equation 2

Given: R = 100 milligrams, a = 1 years = 365 days, b = 138.39 days

Substitute these values into equation 2

R' = 100/(2³⁶⁵⁰⁰/¹³⁸³⁹)

R' = 100/(6.222)

R' = 16.07 milligrams of plonium-210
