Answer:
x = 2.5m/s.
Step-by-step explanation:
Given that F = 0.5 + 0.004(x + 50)(x – 2.5), where x is the speed in m/s and F is the force in N. To know the speed, x, with F = 0.5N, we have:
0.5 = 0.5 + 0.004(x + 50)(x – 2.5)
This gives
0.004(x + 50)(x – 2.5) = 0 (after adding –0.5 to both sides).
For the multiplication to be 0, (x + 50)(x – 2.5) = 0 because 0.004 is not equal to 0.
Hence
x = –50 or x = 2.5
Since it is said from the question that x is positive then x = 2.5m/s.
The two stadiums with the largest capacities are Marshfield Stadium and Bowden Stadium. Marshfield Stadium has a capacity of 7,675 more than Bowden. If the combined capacity for the two stadiums is 210,355, find the capacity for each stadium.
Answer: Capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.
Step-by-step explanation:
Let x = Capacity of Marshfield Stadium.
y = Capacity of Bowden.
As per given, we have
x - y = 7,675 (i)
x+y = 210,355 (ii)
2x = 218030 (iii)
[tex]\Rightarrow\ x= \dfrac{218030}{2}\\\\\Rightarrow\ x= 109015[/tex]
Put value of x in (i) , we get
109015 - y = 7675
⇒ y= 109015 - 7675
⇒ y= 101,340
Hence, capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.

2. Rewrite the equation 8x + 4y = 16 in slope-intercept form.
3. Rewrite the equation 20x - 5y = 30 in slope-intercept form.
Answer:
1. 126
2. y = -2x + 4
3. y = 4x - 6
Step-by-step explanation:
1. 12 + 6 * 19 = 126
2. 8x + 4y = 16
(4y = -8x + 16) / 4
y = -2x + 4
3. 20x - 5y = 30
(-5y = -20x + 30) / -5
y = 4x - 6

Answer:
D. Both a relation & a function.
Step-by-step explanation:
A relation is a set of one or more ordered pairs. A function is a relation in which each input has exactly one output. A set of ordered pairs represents a function if, for every value of x, there is only one value of y. In the given situation, the x-coordinate is the number of weeks since she starts recording and the y-coordinate is the number of books read per week. It can be seen from the given set that each x-value corresponds with exactly one y-value. Therefore, the set of ordered pairs is best described as both a relation and a function.

5. A video store charges a monthly
membership fee of $12.00, but charges to
rent each movie is only $1.50 per movie.
Another store has no membership fee, but it
costs $3.00 to rent each movie. How many
movies need to be rented each month for
the total fees to be the same from either
company?
Answer:
8
Step-by-step explanation:
With the information from the question, you create the equation 1.5x+12=3x where x represents the fee per movie. subtract 1.5x on each side, leaving you with 12=1.5x, and divide 12 by 1.5, leaving you with the answer of x=8.

Find the slope, or rate of change, from the following ordered pair
(16,2) and (32,4)
Answer:
m = [tex]\frac{1}{8}[/tex]
Step-by-step explanation:
Slope Formula is...
m= rise / run or [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Two Coordinate Points / Ordered Pair: (16,2) and (32,4)
Your rise is...
4 - 2
Your run is...
32 - 16
Together the fraction reads...
(4 - 2) / (32 - 16)
Then do the subtracting to get....
2 / 16 ( 2 over 16)
Don't forget to simplify...
*2 can go into 2 and 16
Making the equation....
1 / 8 (one over 8)
So your m (slope) is ... [tex]\frac{1}{8}[/tex]
