True/False?: A best-fit line is created to model data comparing the gasoline consumed by a car (x) and the distance traveled in the car (y). The equation is y=24x−1. One possible explanation for the y-intercept being −1 is that cars that idle (sit still) also use some gas. So, while the model predicts that cars get 24 miles of travel per gallon of gas consumed, some gas is consumed just by a car running (not traveling).

Find the annual percentage yield of a saving account that pays 2.75% compounded quarterly
Answers
Answer:
The annual percentage yield is of 2.78%.
Step-by-step explanation:
Annual percentage yield of an account:
The annual percentage yield of an account compounded n times during the year with a decimal interest rate of r is given by:
[tex]Y = (1+\frac{r}{n})^n - 1[/tex]
Pays 2.75% compounded quarterly
This means that [tex]r = 0.0275, n = 4[/tex]. So
[tex]Y = (1+\frac{r}{n})^n - 1[/tex]
[tex]Y = (1+\frac{0.0275}{4})^4 - 1[/tex]
[tex]Y = 0.0278[/tex]
0.0278 = 2.78%
The annual percentage yield is of 2.78%.

(q1) Find the area of the region bounded by the graphs of y = x - 2 and y2 = 2x - 4.
Answers
the area of the region bounded by the graphs of y = x - 2 and [tex]y^2 = 2x - 4[/tex], is 0.67. Option D
To find the area of the region bounded by the graphs of y = x - 2 and[tex]y^2 = 2x - 4,[/tex]we need to determine the points of intersection between the two graphs and then integrate the difference between the two functions within the bounds.
Let's begin by finding the points of intersection:
Setting the two equations equal to each other, we have:
x - 2 = 2x - 4
Simplifying the equation, we get:
x = 2
Substituting x = 2 into either equation, we find the corresponding y-value:
y = 2 - 2 = 0
So the points of intersection are (2, 0).
Now, we need to determine the bounds for integration. The graphs intersect at x = 2, so the region of interest lies between x = 0 and x = 2.
To find the area, we integrate the difference between the two functions within these bounds:
A = ∫[0,2] (x - 2 - √(2x - 4)) dx
We can simplify this equation as follows:
A = ∫[0,2] (x - 2 - (2x - 4)^(1/2)) dx
= ∫[0,2] (x - 2 - (2(x - 2))^(1/2)) dx
= ∫[0,2] (x - 2 - 2(x - 2)^(1/2)) dx
To evaluate this integral, we need to use numerical methods or software. Integrating the equation within the bounds gives us an area of approximately 0.67 sq. units.Therefore, the correct answer is Option D
