A jogger runs on a path at a speed of 0.075 miles per minute. A second jogger starts 5 minutes later from the same spot, but runs at a rate of 0.1 miles per minute. Create a pair of parametric equations to represent the paths of the joggers. How far down the path from the starting point does the second runner overtake the first runner?
Answer:
1.5 miles
Step-by-step explanation:
graph on desmos graphing calculator
(0.075t, 0.1t-5)
The second runner will overtake after 1.5 miles.
What is an Equation?An equation is a mathematical statement that is formed when two algebraic expressions are equated using an equal sign.
Let t represent the time taken at which both the joggers meet
Then the distance covered is given by
For jogger A = 0.075 t
For jogger B = 0.1 (t-5)
0.075 t = 0.1t - 0.5
0.025t = 0.5
t = 20 seconds
The distance at which they meet is
=0.075 * 20
= 1.5 miles

Answer:
59°
Step-by-step explanation:
According to the given description, [tex] \angle QRS[/tex] is the exterior angle of [tex] \triangle PQR[/tex]
So, by exterior angle property of a triangle, we have:
[tex] m\angle QRS=m\angle RPQ+m\angle PQR\\\\
(10x - 1)\degree = (3x +17)\degree+(2x +12)\degree\\\\
(10x - 1)\degree = (3x +17+2x +12)\degree\\\\
(10x - 1)\degree = (5x +29)\degree\\\\
(10x - 1)= (5x +29)\\\\
10x - 5x = 29 + 1\\\\
5x = 30\\\\
x = \frac{30}{5}\\\\
x = 6\\\\
\because m\angle QRS = (10x - 1)\degree \\\\
\therefore m\angle QRS = (10\times 6- 1)\degree \\\\
\therefore m\angle QRS = (60- 1)\degree \\\\

How do you do this geometry
Answer:
y = 62
z = 35
Step-by-step explanation:
Basically, you know one of the angles, that is 62. And since y is the same angle as 62 that would also be 62. And since the straight line is 180, just subtract 180 - 62, and that equals 118. So, then I just tried to find numbers that when multiplied by 6, and then subtracted by 92, equal 118. Honestly, z was just a guessing game for me. But I do know that I got the right answer, i just didn't figure it out the right way lol.
Good luck!
Answer:
y = 118°
z = 35
Step-by-step explanation:
All 8 of the angles formed by these three lines are only two different measures. They are all either 62° or
(180°-62°) 118°.
Also, any two of the angles are either the same or they add up to 180°.
The angle marked y° and the 62° angle are called "consecutive" angles or "same-side interior angles. They add up to 180°
y + 62° = 180°
y = 118°
The angle marked y° and the angle marked (6z - 92)° are called "vertical angles" and they are equal.
6z - 92 = 118°
add 92.
6z = 210°
Divide by 6.
z = 35

1.in an earlier example, we examined data on highway gas mileages of model year 2012 midsize cars. the following dotplot shows the difference (highway – city) in epa mileage ratings for each of the 24 car models from the earlier example.
The fuel economy lies between 7 to 12 and minimum fuel economy in the city
The dot above 12 represents that there's one automobile whose difference (dual carriageway-city) in EPA milege scores is 12 . this is the automobile model have 12 EPA higher economy than within the city. From the graph we have a look at that the minimum gas financial system within the town as opposed to on the motorway for the auto model is extra in metropolis than motorway.whilst the median and maximum gas economic system is more on motorway than in the town.whilst the gas economy on motorway is more and lies between 7 to twelve .The time period "gas financial system" describes how many miles an vehicle can go on a given amount of fuel. For electric powered cars, it's far expressed in miles consistent with gallon or miles in keeping with gallon gas equivalent (or MPGe). The similarly an vehicle can travel on a tank of gasoline and the extra its gasoline efficiency, the higher the miles consistent with gallon.To learn more about fuel economy visit:

5 + 100
Which expression could be a step in rewriting this sum?
Answer:
the answer of this qst is A
Applying the least common multiple, the fraction is rewritten as
[tex]\frac{4200(x+100)}{x(x+100)} + \frac{4200x}{x(x+100)}[/tex]
Which is option A.
---------------------------------------
The fraction given is:
[tex]\frac{4200}{x} + \frac{4200}{x + 100}[/tex]
When two fractions with different denominators are added, the first step is finding the least common multiple of the denominators. The lcm of x and x + 100 is x(x + 100), thus we use it to factor the fraction.
[tex]\frac{4200}{x} + \frac{4200}{x + 100} = \frac{4200\frac{x(x+100)}{x}}{x(x+100)} + \frac{4200\frac{x(x+100)}{x+100}}{x(x+100)} = \frac{4200(x+100)}{x(x+100)} + \frac{4200x}{x(x+100)}[/tex]

Gabriel is buying bagels for a family gathering. Each bagel costs $1.75. Answer the questions below regarding the relationship between the total cost and the number of bagels purchased.
The independent variable, x, represents the
, and the dependent variable is the
, because the
depends on the
.
A function relating these variables is N(x) =N(x)=
.
So N(14) =N(14)=
, meaning 1414
.
Answer:
Independent Variable: Number of bagels bought
Dependent Variable: Total cost because it depends on the number of bagels bought.
Function: N(x)=1.75x
So, if x is the number of bagels bought, N(14) means that 14 bagels were bought. So you multiply 14 by the price; 1.75. So, N(x)=1.75*14 = $24.5
Step-by-step explanation:
Answer:
The independent variable, x, represents the number of bagels purchased, and the dependent variable is the total cost of the bagels, because the total cost of the bagels depends on the number of bagels purchased.
A function relating these variables is V(x) =1.75x.
So V(14) = 24.5, meaning 14 bagels will cost 24.5 dollars.
