We are standing on the top of a 896 feet tall building and launch a small object upward. The object's
vertical position, measured in feet, after t seconds is h(t) = – 16t+ 160t + 896. What is the highest
point that the object reaches?

Answer:

13 minutes and 30 seconds

Step-by-step explanation:

Okay so first you would divide 128 by 576. But since it takes her 3 minutes just to type 128 words you have to multiply 4.5 times 3. It will take her 13.5 minutes to type 576 words or 13 minutes and 30 seconds.

Answer:

Penguins can swim at a speed of 19.77 miles per hour.

Step-by-step explanation:

Since penguins can swim at speeds of up to 29 feet per second, to convert this speed to miles per hour, knowing that 1 mile is equal to 5280 feet, the following calculation must be performed:

1 hour = 60 minutes

1 minute = 60 seconds

1 hour = 60x60 seconds = 3,600 seconds

29 x 3,600 = feet per hour = 104,400

104,400 / 5,280 = miles per hour = 19.77

Thus, penguins can swim at a speed of 19.77 miles per hour.

Answer:

22/7 - irrational number

1.141141114 - irrational number

17/4 - rational number

-6 - integer

[tex]\frac{\pi }{2}[/tex] - irrational number

0 - whole number

9 - natural number and whole number

21/3 - natural number and whole number

Step-by-step explanation:

natural numbers would be numbers 1,2,3,4,5,6,7...

whole numbers would be numbers 0,1,2,3,4,5,6...

integers are negative whole numbers

rational numbers are fractions and numbers that have decimal points

irrational numbers are number such as [tex]\pi[/tex] or [tex]\sqrt{5}[/tex]

3 hours

15 x 3 = 45 miles

Answer:

The required sample size is 329.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

31% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money.

This means that [tex]\pi = 0.31[/tex]

Confidence level is not given, so we assume 95%.

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

What is the required sample size if you want to estimate this proportion with a margin of error of 0.05?

We need a sample size of n. n is found when M = 0.05. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.05 = 1.96\sqrt{\frac{0.31*0.69}{n}}[/tex]

[tex]0.05\sqrt{n} = 1.96\sqrt{0.31*0.69}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.31*0.69}}{0.05}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.31*0.69}}{0.05})^2[/tex]

[tex]n = 328.6[/tex]

Rounding up

The required sample size is 329.

Answer:

150

Step-by-step explanation:

100%/ x% = 219/ 416

Cross multiply

x = 150 %

219 is 150% of 416

Answer:

2

Step-by-step explanation:

[4^2/(-1+3)^3+2*10] / (10+1)

= [16/8+20] / 11

= 22/11

=2

Hope this helps :) Giving me brainiest would help a lot :))

Answer:

Step-by-step explanation:

So diameter is 9.

Circumference = pi x d

= 22/7 x 9

=28.29inch.

Answer:

104 cm 3

Step-by-step explanation:

4×4×2 = 32

6×6×2 = 72

32+72 = 104

Answer:

8.94 if no rounding is necessary.

Step-by-step explanation:

Pythagorean Theorem. What we know is only one leg and the hypotenuse, sooo...

8² + b² = 12²

64 + b² = 144

Subtract 64 from both sides...

64 - 64 + b² = 144 - 64

b² = 80

[tex]\sqrt{80}[/tex] = 8.94 if you're not rounding.

Since KLM and MLN are complementary they add up to 90 degrees.

LM bisects KLN so it divides it to two equal parts so 90/2= 45 degrees

So, KLM and MLN are both 45 degrees.

Answer:

29 degrees I believe

Step-by-step explanation:

If each triangle is worth 180 degrees, then the answer is 29 degrees.

Answer:

d=7

Answer:

Ima say the answer is 9, likely she bought 6 more new and with the fire half were destroyed of this 6 new posters only are 3 left so she has 12 posters left that means only 3 are added to how much posters she had before, so in some words she started with 9 also 9+3=12.

For where it says write and equation I think the answer would be something like 9+6-3. In where it says work I want to assume is your explaination so you can use the first paragraph I made. Check Its prob a re do of the work you have done to make sure its right. Coming with "Define the value" Im not sure of this but i think is to define your equation.
