If a^b=x, what is a^(b+2)?
prisoha [69]
\bf \boxed{a^b=x}\implies \sqrt[b]{a^b}=\sqrt[b]{x}\implies \boxed{a=\sqrt[b]{x}}\\\\
-------------------------------\\\\
a^{b+2}\implies a^b\cdot  a^2\implies \boxed{x}\cdot \left( \boxed{\sqrt[b]{x}} \right)^2\implies x\cdot \sqrt[b]{x^2}\implies x\sqrt[b]{x^2}

jek_recluse [69]

Answer:

The probability of drivers who are not intoxicated is P(I¯) and is given as 0.99411.

Step-by-step explanation:

As the event is indicated as I for the drivers who are intoxicated, the value of I¯ is for the drivers who are not intoxicated. Its value is calculated as follows

P(I¯)=1-P(I)

P(I¯)=1-0.00589

P(I¯)=0.99411

So the probability of drivers who are not intoxicated is P(I¯) and is given as 0.99411.

Angle A is 45 
Angle R is 72 because S and R are the corresponding angles in the triangle.

To find angle RVA add 72 and 45 and the subtract by 180.

RVA = 180-(72+45) = 63

Hope this helps :)

Cas walks 3/5 miles in 24 min at a steady pace, how long does it take him to walk 2 miles?
san4es73 [151]
Your answer is 80 mins, or an hour and 20 mins. You simply turn that fraction to a decimal by diving 3 with 5. This should turn out to be 0.6. Then you multiply the 24 mins with the 2 miles and it turns out to be 48. After this, you divide 48 by 0.6 and you get 80.
