Which inverse operation would be used to verify the following equation? 102 ÷ 3 = 34

Answers

An inverse operations is the reverse of the equation. For example, since it's 102 ÷ 3 = 34, to get the inverse you would take the opposite sign of "÷" and make it "×," while changing the equal sign to make the statement true. The inverse operation used to verify this is 102 = 3 × 34

Which of the following accurately shows the range of the function defined below?

Answers

Answer: The answer is (b) (2, ∞)

Step-by-step explanation: We are given a function f(x) in the figure and we are to select out of the given options that accurately shows the range of the function defined.

$\textup{For }x < 0, \textup{we have}~f(x)=3.$

$\textup{For }0\leq x<2,\textup{ we have }f(x)=x^2+2\geq 2.$

$\textup{For }x\geq 2,\textup{ we have }f(x)=(1)/(2)x+5\geq 5.$

Therefore, the range of the function f(x) will be greater then or equal to 2. So, the range will be [2, ∞).

Thus, the correct option is (b) (2, ∞).

it's b

Earlier this year in a drug bust in Shanghi, China, police seized 2.4 tons of methamphetamines. If a typical dosage is 50mg, how many doses is that bust, which the Chinese police prevented from being sold to the public?

Answers

2.4 tons=2.4 tons*(1,000 Kg / 1ton)*(1,000,000 mg / 1 kg)=
=2,400,000,000 mg=2.4 x 10⁹ mg

Now, we solve this problem by the rule of three.

50 mg ---------------------1dose
2.4x10⁹ mg---------------- x

x=(2.4 x 10⁹ mg * 1 dose) / 50 mg=48,000,000 doses.

Answer: 48,000,000 doses
