<h2 />

A) True
B) False
C) True

<h2 /><h2><u>True or false</u></h2>

Since Leia and Thaddeus are reading the same 225-page book, and Leia starts reading the book and plans to read 25 pages a day while Thaddeus has already read 45 pages and is reading 20 pages a day, to determine if each statement is true or false the following calculations must be performed:

A) Leia will finish the book in 9 days.

225/25 = X
9 = X

Therefore, it is true that Leia will finish the book in 9 days.

B) f (x) = 20x represents the number of pages Thaddeus has read in x days.

20 x 5 = 200
45 + 20 x 5 = 245

Therefore, it is false that this equation represents the number of pages Thaddeus has read in x days.

C) They will both finish the book in 9 days.

45 + 20 x 9 = X
45 + 180 = X
225 = X

Therefore, it is true that they will both finish the book in 9 days.

Answer:

a) 72

b) $259.2

Step-by-step explanation:

A- The bus travels 40 miles on 8 gallons of gasoline. The bus is traveling 360 miles in total.

360/40= 9

9*8= 72

B- $3.60 per gallon and 72 gallons in total.

3.60*72=259.2

$259.2

What are the coordinates of the vertex of the parabola represent by the equation y=-5x^2+30x-25

Jobisdone [24]

Answer:

The coordinate of the vertex of the parabola is (h,k) = (3,20)

Step-by-step explanation:

The given equation of the parabola is $y=-5x^2+30x-25$

Now, the General Parabolic Equation is of the form:

$y = a (x-h)^2 + k$ , then the vertex is the point (h, k).

Now, to covert the given equation in the standard form:

$y=-5x^2+30x-25 = -5(x^2 -6x + 5)$

Using the COMPLETE THE SQUARE METHOD,

$-5(x^2 -6x + 5) = -5(x^2 -6x + (3)^2 + 5 - (3)^2)\\\implies -5(((x^2 -6x +(3)^2) + 5 - 9)\\= -5((x-3)^3 -4)\\= -5(x-3)^2 + 20$

or $y = -5(x-3)^2 + 20$

⇒The general formed equation of the given parabola is

$y = -5(x-3)^2 + 20$

Comparing this with general form, we get

h = 3, k = 20

Hence, the coordinate of the vertex of the parabola is (h,k) = (3,20)
