How far does the first car will drive in the 2 hours head start it gets? Now, at t = 2 hours, both cars are moving. How much faster is the second car than the first car? You can determine this by dividing the head start by the difference in the two speeds. If car 1 has a 20-mile head start, and car two is five mph faster, then it will take 20/5 = 4 hours to catch up.

Answers

let they meet after second car travels for x hours'
let v be the speed  of second car and V be speed of first car.
Then time taken by first car=x+2
V(x+2)=vx (distance covered is same.)
[tex] \frac{v}{V} = \frac{x+2}{x} subtract 1 from both sides \frac{v-V}{V} = \frac{2}{x} v-V= \frac{2V}{x} [/tex]

Solve the problem. Round to the nearest hundredth of a percent if needed. During clinical trials of a new drug intended to reduce the risk of heart attack, the following data indicate the occurrence of adverse reactions among 1100 adult male trial members. What is the probability that an adult male using the drug will experience nausea?


A. 2.02%

B. 1.73%

C. 27.59%

D. 2.18%

Answers

Based on the given table above, the correct answer would be option D. 2.18%. So how did we get this result. Looking at the table, the number of adults experiencing nausea is 24 and the total number of trial members is 1100. So given these values, the probability of getting nausea (as a percentage) is (24/1100)*100. (0.0218)*100, so we get 2.18. Which gives the probability of 2.18%. Hope this answer helps.

describe how to draw a line that passes through the origin and has a slope of 3/5

Answers

A slope of 3/5 means it rises 3 units and runs 5 units. Thus, to draw such a line, we go up three units from the origin and go to the right 5 units after this point. The point obtained will be one point on the line. We continue this procedure for two to three points and then join them to obtain a line.

The maximum gas mileage for a compact car is estimated using the graph shown below.


The average gas mileage for an SUV is modeled by the function m(s)=−0.015(s−55)2+15, where s is the SUV's speed in miles per hour.


The difference in maximum mileage between these two vehicles is _____ mpg (miles per gallon).


Enter the number that correctly fills in the blank in the previous sentence.

Answers

the graph's maximum is at 33 mpg for reference −0.015(x−55)2+15so just plug it inlet's set y to 0

y=−0.015(x−55)2+15 0=−0.015(x−55)2+15 subtract 15 −15=−0.015(x−55)2 divide both sides by -0.015 1000=(x−55)2
the other maximum is at x=55
and we want the y value
at x=55, y=-0.015(55-55)^2+15 y=-0.015(0)+15 y=15
 the compact has a max of 33mpg and the SUV 15mpg

so you would subtract the 33 and the 15

A flagpole is located at the edge of a sheer y = 70-ft cliff at the bank of a river of width x = 40 ft. See the figure below. An observer on the opposite side of the river measures an angle of 9° between her line of sight to the top of the flagpole and her line of sight to the top of the cliff. Find the height of the flagpole.

Answers

I would solve this using tangents.  Let h be height of flagpole.
Set up 2 right triangles, each with a base of 40.
The larger triangle has height of "h+70"
Smaller triangle has height of 70.

Now write the tangent ratios:
[tex]tan A = \frac{h+70}{40} , tan B = \frac{70}{40} [/tex]

Note: A-B = 9
To solve for h we need to use the "Difference Angle" formula for Tangent
[tex]tan (A-B) = \frac{tanA - tanB}{1+tan A tan B}[/tex]
Plug in what we know:
[tex]tan(9) = \frac{ \frac{h+70}{40} - \frac{70}{40}}{1+ (\frac{h+70}{40})(\frac{7}{4})} [/tex]
[tex]tan (9) = \frac{ \frac{h}{40}}{ \frac{7h +650}{160}} = \frac{4h}{7h+650} [/tex]
[tex]h = \frac{650 tan(9)}{4-7 tan(9)}[/tex]
[tex]h = 35.6[/tex]

If we plot the points and connect them, we get this triangle: 

 

Let point 
A=(xA,yA)
B=(xB,yB)
C=(xC,yC) 



------------------------------- 
Let's find the equation of the segment AB 


Start with the general formula 

 


Plug in the given points 

 


Simplify and combine like terms 

 


So the equation of the line through AB is  


------------------------------- 
Let's find the equation of the segment BC 


Start with the general formula 

 


Plug in the given points 

 


Simplify and combine like terms 

 


So the equation of the line through BC is  




------------------------------- 
Let's find the equation of the segment CA 


Start with the general formula 

 


Plug in the given points 

 


Simplify and combine like terms 

 


So the equation of the line through CA is  




So we have these equations of the lines that make up the triangle 


 



So to find the equation of the line that is perpendicular to  that goes through the point C(2,-5), simply negate and invert the slope  to get 

Now plug the slope and the point (2,-5) into  


 

 Solve for y and simplify 

So the altitude for vertex C is  



Now to find the equation of the line that is perpendicular to  that goes through the point A(4,5), simply negate and invert the slope to get  

Now plug the slope and the point (2,-5) into  


 

 Solve for y and simplify 

So the altitude for vertex A is  




Now to find the equation of the line that is perpendicular to  that goes through the point B(-4,1), simply negate and invert the slope to get  

Now plug the slope and the point (-4,1) into  


 

 Solve for y and simplify 

So the altitude for vertex B is  



------------------------------------------------------------ 
Now let's solve the system 


 

 Plug in  into the first equation 

 Add 2x to both sides and subtract 2 from both sides 

 Divide both sides by 3 to isolate x 


Now plug this into  

 

 



So the orthocenter is (-2/3,1/3) 

So if we plug in  into the third equation , we get 


 


 


 

 

So the orthocenter lies on the third altitude

explain the difference between 1/(sinx) and ((sin^-1)x) ...?

Answers

1/sin(x) is the inverse of the entire value of sin(x), while sin⁻¹(x) is the inverse of the value of x. These are different operations so yield different answers. For example, let x = π/2
1/sin(π/2) = 1
sin⁻¹(π/2) does not exist because π/2 lies outside the range of sin(x).

Eugenia wants to find out how fast she walked along the hiking trail that took her 1.5 h to complete. She counted the number of steps with a pedometer and got 10000 steps. in order to calculate the distance she walked she estimated the length of her stride. she walked 10 steps three times at her usual rate and measured the distance with a measuring tape (the smallest division is 1cm) and got 745cm, 748 cm, 739 cm. Find the length of her stride. What is the length of the hiking trail? What are absolute and relative uncertainties in that length?

Answers

1) length of her stride

- 745/10 = 74.5

- 748/10 = 74.8

-739/10 = 73.9

Average: 74.5 + 74.8 + 73.9]/3 = 74.4 cm

2) length of the hiking trial

74.4 cm/step * 10,000steps = 744,000 cm = 7,440 m = 7.4 km

3) Absolute error

legnth with the smallest step measure: 73.9 * 10,000 = 739,000 cm

length with the largest step measure: 74.8 * 10,000 = 748,000 cm

maximum error 744,000cm - 739,000cm = 5,000 cm

4)  relative error

[absolute error / measure] * 100

[5,000 cm / 744,000 cm] * 100 = 0.67%
