The correct answer is 3, it is irrational and equal to 5\sqrt{2}.

The first step is to figure out the answer, then we can deduct whether it is rational or not, giving us our answer. To solve this, we first need to simplify \sqrt{32}. \sqrt{32} is equal to \sqrt{2 * 2 * 2 * 2 * 2}, which is equal to 4\sqrt{2}. Now our expression is 4\sqrt{2} + \sqrt{2}. This simplifies to 5\sqrt{2}. Since this expression has a square root, it is irrational, and since the result is 5\sqrt{2}, the answer is 3).

Your new phew is standing on his deck which is 4 feet off the ground. He tosses his toy up into the air. The equation h(t) = -2t
Tpy6a [65]

Answer:

The height of the toy is 9 feet after 1 second

Step-by-step explanation:

we have

h(t)=-2t^2+7t+4

where

h(t) is the toys height from the ground

t is the time in seconds

so

For t=1 sec

substitute the value of t in the quadratic equation and solve for h(t)

h(1)=-2(1)^2+7(1)+4

h(1)=9\ ft

Andrei [34K]

Answer:

The probability that the town has 30 or fewer residents with the illness = 0.00052.

Step-by-step explanation:

So, we have the following set of data or information or parameters given from the question above and they are; the number of people living in that particular society/community/town = 74,000 residents and the proportion of people that the diseases affected = .000215.

The first step to do is to determine the expected number of people with disease. Thus, the expected number of people with disease = 74,000 × .000215 = 15.91.

Hence, the probability that the town has 30 or fewer residents with the illness = 1.23 × 10^-7 × 15.91^30/ 2.65253 × 10^-32 = 0.00052.

Note the formula used in the calculating the probability that the town has 30 or fewer residents with the illness =  e^-λ × λ^x/ x!

I need help with #10!
DiKsa [7]

Answer: 6 years old.

Step-by-step explanation:

For this exercise let "x" represents your present age.

According to the information provided in the exercise, you know that  In three years, Chad will be three times your present age.

Then, your age in three years can be represented with the following expression:

x+3

Knowing at that time Chad's age will be three times yours and you will be half as old as old as Chad, you can write the following equation to represent this situation:

x+3=\frac{3x}{2}

Therefore, the final step is to solve for "x" in order to find its value.

You get that this is:

2(x+3)=3x\\\\2x+6=3x\\\\6=3x-2x\\\\x=6
