Using disks ...
$V= \pi \int\limits^5_2 {(x-1)^{2}} \, dx =\pi(\frac{1}{3}(5^{3}-2^{3})-(5^{2}-2^{2})+(5-2))=21\pi$

The volume is 21π units³ ≈ 65.97 units³

'Polonium-210 is a radioactive substance with a half-life of 138 days. If a nuclear

Tatiana [17]

Answer:

<u>59.0891 g (rounded to 4 decimal places)</u>

Explanation:

<em>Half-life time</em> of a radioactive substance is the time for half of the substance to decay.

Thus, the amount of the radioactive substance that remains after a number n of half-lives is given by:

$A=A_0\cdot (1/2)^n$

Where:

A is the amount that remains of the substance after n half-lives have elapses, and

A₀ is the starting amount of the substance.

In this problem, you have that the half-live for your sample (polonium-210) is 138 days and the number of days elapsed is 330 days. Thus, the number of half-lives elapsed is:

330 days / 138 days = 2.3913

Therefore, the amount of polonium-210 that will be left in 330 days is:

$A=310{g}\cdot (1/2)^{2.3913}=59.0891g$

Let ƒ(x) = x + 1 and g(x) = 5x. Evaluate the composition (ƒ ∘ g)(–1). Question 2 options: A) (ƒ ∘ g)(–1) = 6 B) (ƒ ∘ g)(–1) = –4

Papessa [141]

Answer:

answer B

Step-by-step explanation:

hello,

$f(x)=x+1\\g(x)=5x \ \ so\\(fog)(-1)=f(g(-1))=f(-5)=-5+1=-4$

so the winner is the answer B

Mr. Davis bought 2 chairs during the sale. The regular price of each chair was $168. What was the total price, in dollars, for b

S_A_V [24]

Answer:

tatol price= $335.16

Step-by-step explanation:

regular price for one item= $168

sale=1/2 %

168 × 0.5/100 = 0.84 (discount)

price of discounted chair= 168-0.86

= 167.16

168+167.16 = $335.16
