If an object is dropped from a height of 144 feet, the function h(t)=-16t^2+144 gives the height of the object after t seconds.
shtirl [24]

Answer:

A. 3s

Step-by-step explanation:

The height of the object after t seconds is given by:

h(t) = -16t^2 + 144

When will the object hit the ground?

It hits the ground after t seconds, and t is found when h(t) = 0. So

h(t) = -16t^2 + 144

0 = -16t^2 + 144

16t^2 = 144

t^2 = \frac{144}{16}

t^2 = 9

t = \sqrt{9}

t = 3

3 seconds, so the correct answer is given by option a.

g On any day, the probability of rain is 0.3. The occurrence of rain on any day is independent of the occurrence of rain on any
Ksju [112]

Answer:

0.249579

Step-by-step explanation:

P(rain) = 0.3

P(no rain) = 1 - 0.3 = 0.7

The event of rain falling a second time within the next 5 days is possible in these ways

1. Rain on days 1 and 2

2. Rain on days 1 and 3; none on day 2

3. Rain on days 1 and 4; none on days 2 and 3

4. Rain on days 1 and 5; none on days 2, 3 and 4

5. Rain on days 1 and 6; none on day 2, 3, 4 and 5

P(\text{second rain within 5 days}) = 0.3^2+0.3^2\times0.7+0.3^2\times0.7^2+0.3^2\times0.7^3+0.3^2\times0.7^4 = 0.3^2(1+0.7+0.7^2+0.7^3+0.7^4)= 0.09\times2.7731=0.249579

25 less than 3 times a number is 38. What is the number?
Nookie1986 [14]

You would set up the problem like this: 3n-25=38

To solve for n:

3n-25=38

   +25 +25          (Add 25 to both sides)

3n=63

/3   /3                  (Divide by 3 on both sides)

n=21

The answer is 21.
