Answer:

- 2(x - 6)(x - 4)

Step-by-step explanation:

Given

- 2x² + 20x - 48 ← factor out - 2 from each term

= - 2 (x² - 10x + 24) ← factor the quadratic

Consider the factors of the constant term (+ 24) which sum to give the coefficient of the x- term (- 10)

The factors are - 6 and - 4, since

- 6 × - 4 = + 24 and - 6 - 4 = - 10, thus

x² - 10x + 24 = (x - 6)x - 4) and

- 2x² + 20x - 48 = - 2 (x - 6)(x - 4) ← in factored form

You run around the perimeter of a baseball field at a rate of at least 10 feet per second. Which of the following are possible a
vovikov84 [41]
1) we have to calculate the lenght of the baseball field.

perimeter of the baseball field=2(radius)+lenght of a semicircle.

2(radius)=2(175 ft)=350 ft
lenght of a semicircle=40% of a circumference=(40/100)(2πr)

Perimeter of the baseball field=2(175 ft) + (40/100)(2π175 ft)=
=350 ft + 140π ft=350 ft + 439.82 ft=789.82 ft,


2)Now, we calculate the amounts of time that it takes you to ruan arount the baseball field.

10 ft------------------------1 second
789,82 ft-----------------    x

x=(789.82 ft * 1 second) / 10 ft=78.98 s≈79 s


answer: 79 seconds.

Help me please, I’m still struggling with y intercepts, rates of change, etc.
BaLLatris [955]

Answer:

(a) The y-intercepts of both functions are the same, 0.  However, the rate of change for the school library is 0.25, while the rate of change for the city library is 0.35.  

(b) The 3-day late fee at the school library is $0.75 and the 3-day late fee at the city library is $1.05.

Step-by-step explanation:

The functions represented in the question are linear, which means that they have a consistent rate of change over time.  In this example, it means that for every day, the late fee charged by each library is the same.  At the school library, the rate of change is 0.25, which means for each day the book is late, the school charges a fee of $0.25.  At the city library, the table shows that for each day the book is late, the city charges a fee of $0.35.  So, the city library is more expensive.  Y-intercept refers to the initial cost, or how much do the libraries charge if the book is not late, or turned in on time.  In this case, neither library charges a fee for books turned in on time, so both would have a y-intercept of 0.

Which of the following equations represents a line that passes through the points ( − 3 , − 3 ) and (−2,0)?
jek_recluse [69]

y=3x+6

Use

y=mx+b

to calculate the equation of the line, where

m

represents the slope and

b

represents the y-intercept.

Slope is equal to the change in

y

over the change in

x

, or rise over run.
