Answer:

D. 60y + 48

Step-by-step explanation:

You distribute (multiply) the 12 to everything inside the parentheses.

12 X 5y = 60y 12 X 4 = 48

60y + 48 is your answer. Hope this helps.

6 x 10^8 = 600 x 10^6 compare to 3 x 10^6

Since both now have same exponents

so 600/3 = 200

Conclusion: Answer is 2nd option

6 x 10^8 is 200 times larger than 3 x 10^6

The number of cars entering a roadway at a specific exit during the morning rush hour traffic (6AM to 9AM, M-F) is a random vari

rusak2 [61]

Answer:

0.5

Step-by-step explanation:

This is an example of mutually exclusive event in which two or more events cannot occur at the same time or in a single performance.

Therefore, the probability the number of cars entering the roadway is between 4 and 6 cars per minute (inclusive) implies that it is either 4, 5 or 6 cars enter in a minute. Since we have an average of 6 cars per minute, the probability of each of the event occurring is 1/6. This can therefore be calculated as follows:

P(4 or 5 or 6) = (1/6) + (1/6) + (1/6)

= 3/6

= 1/2

= 0.5

Therefore, the probability the number of cars entering the roadway is between 4 and 6 cars per minute (inclusive) is 0.5.

Differentiate Vx(x + 2) with respect to x.

Travka [436]

Answer:

$y'= \frac{3x+2}{2\sqrt{x} }$

General Formulas and Concepts:

Calculus

The derivative of a constant is equal to 0

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Product Rule: $\frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)$

Chain Rule: $\frac{d}{dx}[f(g(x))] =f'(g(x)) \cdot g'(x)$

Step-by-step explanation:

Step 1: Define

$y=\sqrt{x} (x+2)$

Step 2: Rewrite

$y=x^{\frac{1}{2} } (x+2)$

Step 3: Differentiate

Product Rule [Basic Power/Chain Rule]: $y'= \frac{1}{2} x^{\frac{1}{2} -1}(x+2)+x^{\frac{1}{2} }(1)$
Simplify: $y'= \frac{1}{2} x^{\frac{-1}{2}}(x+2)+x^{\frac{1}{2}}$
Rewrite: $y'= \frac{x+2}{2\sqrt{x} } + \sqrt{x}$
Add: $y'= \frac{3x+2}{2\sqrt{x} }$
