The radius of a circle measures 15 ft. What is the circumference of the circle?
Use 3.14 for n, and do not round your answer. Be sure to include the correct unit in your answer

Answer:

Step-by-step explanation:

13 693:n=x, remainder 19  => 13 693=n*x+19

17 191:n=y, remanider 19  => 17 191=n*y+19

n>19

13 693-19=n*x

17 191-19=n*y

13 674=n*x

17 172=n*y

n=(13 674; 17 172)

13 674 = 2*3*43*53

17 172=2²*3⁴*53

n=2*3*53

n=318

whats the question??

Step-by-step explanation:

5. Your track coach is letting you choose between two different workouts.

A: Run 10 minutes on Monday and double that time every day through Friday.

B: Run 30 minutes on Monday and add 10 minutes every day through Friday.

What type of function is represented by plan A? By plan B? Which plan should you choose if you have plans Friday night and want a short workout on Friday? Why? Create a table to justify your answer.

Plan A: Geometric function

Plan B: Arithmetic function

I would choose plan B because Plan A has me working out for 160 minutes on Friday, but I want a short workout that day because I have plans.

Plan A minutes

Plan B minutes

To have lesser workout on Friday, You must choose plan B.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

There are 2 plans.

Plan A : run 10 min on Monday and double that time everyday through Friday.

Here the function is going on as,

10, 2 × 10 = 20, 2 × 20 = 40, 2 × 40 = 80, 2 × 80 = 160

10, 20, 40, 80, 160

This is a geometric Function since the ratio of minutes on two consecutive days is constant which is 2.

Plan B : Run 30 minutes on Monday and add 10 min everyday through Friday.

Here the function is going on as,

30, 30 + 10 = 40, 40 + 10 = 50, 50 + 10 = 60, 60 + 10 = 70

30, 40, 50, 60, 70

This is a arithmetic function since the difference of minutes between two consecutive days is constant which is 10.

If I need shorter workout on Friday, I would choose plan B, since there is only 70 minutes of workout on Friday.

Hence plan B is better in order to keep shorter workout on Friday.

Answer:

f(2) = 25

f(3) = 125

Step-by-step explanation:

Step 1: Define

f(n) = 5ⁿ

f(2) = n = 2

f(3) = n = 3

Step 2: Substitute and Evaluate

f(2) = 5² = 25

f(3) = 5³ = 125

Answer:

f(2)=5² =25

f(3)=5³ =125

Step-by-step explanation:

if f(n)=5^n then we can assume that the given values of 2 and 3 will replace n. so we just write 2 (or 3) as the exponent on 5 rather than n.

Answer:

A) (66438.35, 80241.65)

B) there's very likely to be a genuine case of early transmission failures, that needs be further investigated.

Step-by-step explanation:

From the table, the values of the miles driven are;

82256

There are 50 number (n) of miles driven.

Thus;

Mean = sum of all miles driven/50

Sum of all miles driven = 85092 + 39323 + 64342 + 74276 + 74425 + 37831 + 77539 + 32609 + 89641 + 61978 + 66998 + 67202 + 89341 + 88798 + 59465 + 94219 + 67998 + 40001 + 118444 + 73341 + 77437 + 116803 + 59817 + 72069 + 53500 + 85288 + 32534 + 92857 + 101769 + 25066 + 79294 + 138114 + 64090 + 63436 + 95774 + 77098 + 64544 + 53402 + 32464 + 65605 + 121352 + 69922 + 86813 + 85586 + 59902 + 85861 + 69568 + 35662 + 116269 + 82256 = 3667015

Mean;x' = 3667015/50 ≈ 73340

From online calculations, standard deviation; s ≈ 24899

Now, margin of error is given by;

E = zs/√n

We are told confidence interval is 95%. z - value at that is 1.96 from online sources.

Thus;

E = (1.96 × 24899)/√50

E = 6901.65

Now the 95% confidence interval is given by;

(x' - E), (x' + E)

This gives;

(73340 - 6901.65), (73340 + 6901.65) = (66438.35, 80241.65)

B) From the miles driven, the median is;

(53500 + 85288)/2 = 69394

This value is less than the mean of 73340. Thus, half of the transmission failures already happened before the average running miles. Therefore, there's very likely to be a genuine case of early transmission failures, that needs be further investigated.

C) we are told to use 5000 miles and 95% confidence interval.

Thus; E = 5000 and s remains 24899

The required sample size is given by;

N = (z•s/E)²

N = (1.96 × 24899/5000)²

N ≈ 96

Answer:

1.) 15.26

2.). 5.74 miles

Step-by-step explanation:

1. We will solve this using the pythagorean theorem

Ab² + bc² = ac²

= 13² + 8² = ac²

= 169 + 64 = ac²

233 = ac²

We take square root of both sides to get ac

√233 = ac

15.26 = ac

So the distance from his home to his place of work is approximately equal to 15.26

2. Actual distance = 13 + 8 = 21 miles

21 miles - 15.26 = 5.74miles

Therefore his one way trip would be 5.74 miles shorter everyday.

Answer:

slump, weathering, and creep

Step-by-step explanation:

edge2020

Freezing and thawing cycle in geology is the process in which water gets in between soil space or rock cracks, freeze in a cold season, and then melt in a warmer season, exerting a force on the soil or rock around it. This force is due to the expansion and contraction of water when it changes from ice to liquid water.

The three geological processes slump, weathering and creep all depend on thawing and freezing cycle among other factors.

Slump: Slump is a type of geological process that occurs when coherent mass of loosely consolidated materials or a rock layer moves a short distance down a slope. The movement of a slump is characterized by sliding along a concave-upward or planar surface. Causes includes earthquake shocks, thorough wetting, freezing and thawing, undercutting, and loading of a slope.

Weathering: This is a geological process that results in the gradual disintegration of rocks into smaller sizes. It is one of the most important soil formation process, and is different from erosion by the degree of movement of the soil formed. Weathering does not move the soil from its origin. Thawing and freezing cycle plays a major role in weathering by helping crack up the rocks and by also tearing the rock apart. plays a major role.

Creep: This is the slow, often imperceptible downslope movement of soil or other debris. The effects of creep is often seen in the presence of physical characteristics like bent trees, tilted fences, and cracked walls.  Creep is caused by multiple factors, of which heaving is likely the most important process. Heaving involves the expansion and contraction of rock fragments, and occurs during cycles of wetting and drying, as well as freezing and thawing.

Answer:

P(at least 1 wrong in 10) =0.5160

Step-by-step explanation:

Let A be the event  that there is a problem in the proces. Then the probability of problem with the process is P ( A) = 0.07

Let B be the event  that the process is without the problem. Then the probability of without problem is P ( B) = 0.93

Now we want to find the 10 successive points of event B. Since the events are independent we can find this as

P(B)+P(B)+P(B)+P(B)+P(B)+P(B)+P(B)+P(B)+P(B)+P(B)

or

P(B)^ 10= .93^10=0.48398

As we have to calculate at least 1 in 10 then we will subtract it from 1.

P(at least 1 wrong in 10) = = 1 - .93^10 =1- 0.48398=0.5160

Answer:

3/4 cups

Step-by-step explanation:

First convert 1 1/4 to an improper fraction which would give you 5/4. Next, you have to manipulate 5/4 and 1/2 so they have the same denominator, so you are able to subtract. So 1/2 = 2/4. Next subtract the two to get the remaining amount of flour. 5/4 - 2/4 = 3/4 cups.

Answer: $58.33 (Rounded bc it ends up in becoming a decimal)

Explanation: Let's make an equation for this problem. We know that if she works 3 hours for $25, 3*2=6 with 1 hour leftover. We can substitute those 6 hours for 2 sets of the 3 hours, giving us $50 so far. For the last hour, we have to divide 25 by 3 because it's only 1 hour instead of 3, meaning she'll get paid a third of the original pay rate. 25/3 equals 8.33333333334, so we'll just round that to 8.33, since it's cash. 50+8.33=$58.33. So, you'd earn 58 dollars and 33 cents for working for 7 hours.
