At the beginning of the day, the sum of the stocks in the Dow Jones was
$10,335.24. At the end of the day, the sum of the stocks in the Dow Jones
was $10,215.78. What was the rate of change of the Dow Jones on this
particular day?
Answer:
- 1.15585%
Step-by-step explanation:
Given that:
Sum of stock at beginning = $10,335.24
Sum of stock at the end of the day = $10,215.78
Rate of change of the Down Jones on that day :
The change in price on the day:
Ending - Beginning
10,215.78 - 10,335.24 = −119.46
The rate if change is thus ;
(Change in price / beginning stock price) * 100%
(-119.46 / 10,335.24) * 100%
-0.0115585 * 100%
- 1.15585%
Answer: -1.2%
Step-by-step explanation:

If the radius of a circle is 9 cm, what is the area of the circle?
The diameter of the circle is 100 cm what is the circumference of the circle? (Use = 3.14.)
Step-by-step explanation:
the formula for the area of a circle is
πr²
plug 9 in for r (radius) to get
3.14 (81) = 254.34 cm² as our area
the circumference is equal to πd , with π being pi and d being diameter.
the circumference is then 3.14(100) = 314cm
Use the graph shown. State the number of real zeros of the function.
Answer:
Option B
Step-by-step explanation:
Zeros of a function are defined by the values of x at y = 0,
In other words, x-intercepts of a function graph are the zeros of the function.
Real zeros means graph should intersect or touch the x-axis.
If it is imaginary, the graph will have no x-intercept.
From the graph attached,
There are 3 points where the graph intersects the x-axis.
Therefore, the function will have 3 real zeros.
Option B is the answer.
Match the scenarios to the equations.
Answer:
first one is -4+y=20 second is 4+y=-20

The ratio of teachers to students on a field trip to New York City is 2 to 9. If there are 243 students on the trip,
Answer:
54 teachers
Step-by-step explanation:
Step one:
given data
The ratio of teachers to students on a field trip to New York City is 2 to 9.
That is the ratio is 2:9
We are told that there are 243 students
Required
We want to find the number of teachers
Step two:
Applying the part to part method we have
let the number of teachers be x
2/9= x/243
cross multiply we have
9x= 243*2
9x= 486
divide both sides by 9
x= 54
Hence there are 54 teachers

y = 1/5x
Answer:
y=3x+1
Step-by-step explanation:
You get all the steps you need in order to make a linear graph line. you see 3x is where the x intercept is going to be. you always need to see a number at the end of the equation with either +/- sign as in (+1).
(have a great day!)
two equations are shown in the picture please answer. giving brainiest
Answer:well for the first one I am not sure but I think that since four is over the x there should be 4/x + 3 so tragically I don’t know the answer but I think it should be 12 the x should be 12 because 4x3=12 so yea 12
Step-by-step explanation:and for the other one I don’t know but ima try it should be two because 2x2=4 and so y=1-2x2-4 that’s what I think sorry. I got it wrong and do good on your test for me please
pls help me pls plz plzplz

A florist was looking at her flower order. The ratio of roses to sunflowers was 4 to 9. When she was done, she realized there were 65 MORE sunflowers than roses. How many of each flower was there?
Answer:
[tex]52[/tex] roses and [tex]117[/tex] sunflowers
Step-by-step explanation:
Since the ratio of roses to sunflowers is [tex]4:9[/tex], we can represent how many there are of each as [tex]4x[/tex] and [tex]9x[/tex], respectively. We know that there are [tex]65[/tex] more sunflowers than roses, so we can set up the following equation to solve for [tex]x[/tex]:
[tex]4x+65=9x[/tex]
Solving for [tex]x[/tex], we get:
[tex]4x+65=9x[/tex]
[tex]4x+65-4x=9x-4x[/tex] (Subtract [tex]4x[/tex] from both sides of the equation to isolate [tex]x[/tex])
[tex]65=5x[/tex] (Simplify)
[tex]5x=65[/tex] (Symmetric Property of Equality)
[tex]\frac{5x}{5}=\frac{65}{5}[/tex] (Divide both sides of the equation by [tex]5[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=13[/tex] (Simplify)
Therefore, since [tex]x=13[/tex], we know that there are [tex]4x=4*13=52[/tex] roses and [tex]9x=9*13=117[/tex] sunflowers. Hope this helps!

Step-by-step explanation:
Absolute value function:
|x| = x when x >= 0.|x| = -x when x < 0.Swim 3 feet under water => |-3|
Stand 20 feet above => |20|
Using the absolute value function,
we have |-3| = 3 and |20| = 20.
Since 3 is less than 20, |-3| < |20|. (C)
Thinkers and leaders other than Martin Luther King Jr. have created tension to bring about change.
What evidence from the passage supports this statement?
“Just as Socrates felt that it was necessary to create a tension in the mind so that individuals could rise from the bondage of myths...”

“I just referred to the creation of tension as a part of the work of the nonviolent resister. This may sound rather shocking. But I must confess that I am not afraid of the word tension.”
“Too long has our beloved Southland been bogged down in the tragic attempt to live in monologue rather than dialogue...”
