Answer:

The answer is d(t)=3,906,000 miles.

Step-by-step explanation:

To solve this is pretty easy,

We know that the equation is d(t)=186000t, and since we have to find the distance in 21 seconds, you just have to substitute the variable.

t=time\\d(t)=186000(t)\\d(21)=186000(21)\\d(21)=3,906,000

Determine whether the three segment lengths will produce a triangle. Type yes or no in the space provided.
tresset_1 [31]

Answer:

20 , 20 , 30 will produce a triangle

Step-by-step explanation:

* Lets study how to know if the lengths of the three segments

 can formed a triangle

- It is a fact that in any triangle the sum of the smallest two sides

 must be greater than the largest side

- Lets study some examples

# If the lengths of the three segments are 5 , 6 , 7

∵ 5 and 6 are the smallest

∴ 5 + 6 = 11

∵ 11 > 7 ⇒ the sum greater than the 3rd side

∴ 5 , 6 , 7 can formed a triangle

# If the lengths of the three segments are 5 , 7 , 12

∵ 5 and 7 are the smallest

∴ 5 + 7 = 12

∵ 12 = 12 ⇒ the sum equal the 3rd side

∴ 5 , 7 , 12 can not formed a triangle

# If the lengths of the three segments are 10 , 12 , 24

∵ 10 and 12 are the smallest

∴ 10 + 12 = 22

∵ 22 < 24 ⇒ the sum less than the 3rd side

∴ 10 , 12 , 24 can not formed a triangle

* Now lets solve the problem

∵ The length of the three segments are 20 , 20 , 30

∵ 20 and 20 are the smallest

∴ 20 + 20 = 40

∵ 40 > 30 ⇒ the sum greater than the 3rd side

∴ 20 , 20 , 30 will produce a triangle

A football coach wants to see how many laps his players can run in 15 minutes. During a non-mandatory meeting, the coach asks fo
mestny [16]

Answer:

Step-by-step explanation:

There are three reasons here why randomization is not being applied.

First, the coach is only observing football players attending the meeting.  This is not representative of the entire team.

Second, there is no selection process.  The coach isn't using a random generator or using a similar method.

Third, the players are volunteering for the test.  The results will be biased because of this.

I know this is an exponential function based on the fact the f(x) multiplies. But how do I get an equation from the table? I wil
almond37 [142]

Answer:An exponential function is defined by the formula f(x) = ax, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.

Step 1: Take the natural log of both sides:

Step 2: Simplify the left side of the above equation using Logarithmic Rule 3:

Step 3: Simplify the left side of the above equation: Since Ln(e)=1, the equation reads

Ln(80) is the exact answer and x=4.38202663467 is an approximate answer because we have rounded the value of Ln(80)..

Check: Check your answer in the original equation.

Example 2: Solve for x in the equation tex2html_wrap_inline133

Step 1: Isolate the exponential term before you take the common log of both sides. Therefore, add 8 to both sides: tex2html_wrap_inline135

   

Step 2: Take the common log of both sides:

Step 3: Simplify the left side of the above equation using Logarithmic Rule 3:

Step 4: Simplify the left side of the above equation: Since Log(10) = 1, the above equation can be written

Step 5: Subtract 5 from both sides of the above equation:

is the exact answer. x = -3.16749108729 is an approximate answer..
