In this relationship between the number of miles per gallon on the highway and that in the city for some cars are:
For each additional city mpg, the highway value goes up by
0.9478 mpg.
And It is inappropriate to interpret the intercept because no cars get 0 mpg in the city.
According to the statement
we have given that the relationship between the number of miles per gallon on the highway in the graphical representation and that in the city for some cars.
And we have to give some reasons for the given statements.
So, For this purpose, we know that the
A. In this statement we have to tell that the what is shown in the given relationship in the graph.
So, For each additional city mpg, the highway value goes up by
0.9478 mpg.
And the second statement is
B. I this we have to tell the intercept of the plane in the given Relationship.
So, It is inappropriate to interpret the intercept because no cars get 0 mpg in the city.
So, In this relationship between the number of miles per gallon on the highway and that in the city for some cars are:
For each additional city mpg, the highway value goes up by
0.9478 mpg.
And It is inappropriate to interpret the intercept because no cars get 0 mpg in the city.

Answer:
When Aria sold her house after eleven years it worth was <u>$95,300</u>.
Step-by-step explanation:
Given:
Aria paid $75,000 for her house. Its property value increased by 2.2% per year.
Now, to find the worth of Aria house when sold after eleven years.
Let the amount of house after eleven years be
Amount Aria paid for her house (A) = $75,000.
Rate of property increased per year (r) = 2.2%.
Time (t) = 11 years.
Now, to get the amount of house after eleven years we put formula:
<em>The amount of house after eleven years to the nearest hundred dollars is $95,300.</em>
Therefore, when Aria sold her house after eleven years it worth was $95,300.
Answer:
a. see attached
b. H(t) = 12 -10cos(πt/10)
c. H(16) ≈ 8.91 m
Step-by-step explanation:
<h3>a.</h3>The cosine function has its extreme (positive) value when its argument is 0, so we like to use that function for circular motion problems that have an extreme value at t=0. The midline of the function needs to be adjusted upward from 0 to a value that is 2 m more than the 10 m radius. The amplitude of the function will be the 10 m radius. The period of the function is 20 seconds, so the cosine function will be scaled so that one full period is completed at t=20. That is, the argument of the cosine will be 2π(t/20) = πt/10.
The function describing the height will be ...
H(t) = 12 -10cos(πt/10)
The graph of it is attached.

<h3>b. </h3>See part a.

<h3>c.</h3>The wheel will reach the top of its travel after 1/2 of its period, or t=10. Then 6 seconds later is t=16.
H(16) = 12 -10cos(π(16/10) = 12 -10cos(1.6π) ≈ 12 -10(0.309017) ≈ 8.90983
The height of the rider 6 seconds after passing the top will be about 8.91 m.
