Answer: y = -2x² + 920x - 84168
suppose: the equation of the parabola is y = ax² + bx + c
because the parabola passes through (126,0); (134,3200); (334,0)
=> we have the equations:
126².a + 126b + c = 0
134².a + 134b + c = 3200
334². a + 334b + c = 0
⇒ a = -2
b = 920
c = -84168
=> the equation of the parabola is y = -2x² + 920x - 84168

Nicolas sold 86 newspapers on Monday 79 on Tuesday and 68 on Wednesday and 83 on Friday how many newspapers did Nicholas sell on Thursday if he sold a total of 391 in five days?
Define a variable, write an equation, then solve.
Answer:
75
Step-by-step explanation:
86+79+68+83=316
391-316=75
Answer:
75 newspapers
Step-by-step explanation:
391 is equal to the combination of all the newspapers Nicholas sold over those 5 days. This can be written as an equation:
391 = 86 + 79 + 68 + 83 + x
x represents the number of newspapers Nicholas sold on Thursday.
Now let's solve for x:
First, combine like terms:
391 = 316 + x
now subtract 316 from both sides to isolate x:
391 - 316 = 316 - 316 + x
75 = x
Nicholas sold 75 newspapers on Thursday.

what is the vaule 7 to the 6 power
Answer:
117,649
Step-by-step explanation:
Good luck! <3
Answer:
7 to the 6th power is conventionally written as 76, with superscript for the exponent, but the notation using the caret symbol ^ can also be seen frequently: 7^6.
76 stands for the mathematical operation exponentiation of seven by the power of six.
As the exponent is a positive integer, exponentiation means a repeated multiplication:
The exponent of the number 7, 6, also called index or power, denotes how many times to multiply the base (7).
Thus, we can answer what is 7 to the 6th power as
7 to the power of 6 = 76 = 117649.

In ABC, angle A = 30 degree , angle b=45 degree find the angle c
Answer:
95 degrees
Step-by-step explanation:
in a triangle angles add up to 180 degrees.
a + b + c = 180
30 + 45 + c = 180
85 + c = 180
c= 180 - 85
c= 95 degrees
Over the last week, the daily low temperatures in degrees Fahrenheit have been −2, 6.9, 17 1 2 , −5.1, 24, − 1 4 , and 1.45. List these numbers in order from greatest to least.
Answer:
24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1
Step-by-step explanation:
Given the following temperature values :
2, 6.9, 17 1/2 , −5.1, 24, − 1/4 , and 1.45.
Ordering the values above from greatest to least ; (descending order)
Expressing all temperature values in the same format :
Let's make sure all values are in decimal to make comparison easier :
2.0
6.9
17 1/2 = 35/2 = 17.5
-5.1
24.0
-1/4 = - 0.25
1.45
We begin from the temperature value which is highest :
24 > 17.5 > 6.9 > 2.0 > 1.45 > - 0.25 > - 5.1
Hence ;
24 > 17 1/2 > 6.9 > 2 > 1.45 > - 1/4 > - 5.1

There are two types of cellular phones, handheld phones (H)that you carry and monile phones (M) that are mounted invehicles. Phone calls can be classified by the travelingspeed of the user as fast (F) or slow (W). The probabilitymodel for this experiment has the following information: P[F] =0.5, P[HF] = 0.2, P[MW] = 0.1. What is the sample space ofthe experiment? Calculate the followng probabilites:a) P[W]b) P[MF]c) P[H]
Answer:
Explained below.
Step-by-step explanation:
(1)
Sample space is a set of all possible outcomes of an experiment.
The sample space in this case is:
S = {HF, HW, MF, MW}
(a)
Compute the value of P (W) as follows:
P (F) + P (W) = 1
P (W) = 1 - P (F)
P (W) = 1 - 0.50
P (W) = 0.50
(b)
Compute the value of P (MF) as follows:
P (HF) + P (MF) = P (F)
P (MF) = P (F) - P (HF)
P (MF) = 0.50 - 0.20
P (MF) = 0.30
(c)
Compute the value of P (M) as follows:
P (M) = P (MF) + P (MW)
P (M) = 0.30 + 0.10
P (M) = 0.40
Compute the value of P (H) as follows:
P (H) + P (M) = 1
P (H) = 1 - P (M)
P (H) = 1 - 0.40
P (H) = 0.60

Work Shown:
4/9 + 9/18
8/18 + 9/18 ... see note below
(8+9)/18
17/18
----------------
note: To go from 4/9 to 8/18, we multiply top and bottom by 2. So that's why 4/9 = 8/18.
The diagram below shows a visual representation of why 4/9 = 8/18.
In the top row, I've drawn out 9 rectangles of the same size. Then I've shaded 4 of the 9 rectangles to represent the fraction 4/9. In the bottom row, I've cut each of those 9 rectangles into two smaller equal pieces, so we have 9*2 = 18 rectangles now. Note how the shaded regions are the same size, so this shows 4 green regions doubles to 2*4 = 8 yellow regions; therefore 4/9 is the same as 8/18.
Answer: its 17/18

Answer:
y= -1/2 + 2
Step-by-step explanation:
To find m or the slope you need to find 2 locations that the line intercepts a point on the graph. I used (0,2) and (2,1).
Then you find the difference of the x and y coordinates. (x,y)
X-coordinates: 0 and 2. 0 - 2 = -2
Y-coordinates: 2 and 1. 2 - 1 = 1
A slope fraction is the difference of y over the difference of x coordinates. It would be written as 1/-2 or -1/2. m= -1/2
To find the b value, just look at the y-intercept or where the line intercepts the y-axis. Which is at (0,2). So b=2
Evan is going to the county fair this weekend. The admission to the fair is $5 and the cost per ride is $.50. Write and solve a linear equation to find out how many rides he can go on.
Answer:
Evan can go on 30 rides (based on the assumption that Evan's parent gave him $20)
Step-by-step explanation:
Given that:
The admission to the fair = $5
The cost per ride = $0.50
Let assume that the number of ride Evan can go = x
So if The cost per ride = $0.50
x ride = $0.50x
We are not told that he is given money by anybody, but let assume his parent gave him $20,
Then, if Evan pays $5 for admission into the fair. Then he will have $(20-5) = $15 left
The relation expressing how many rides Evan can go is:
0.5x = 15
Since the cost per ride = $0.5
x rides cost $15/0.5
x = 15/0.5
x = 30
Hence, Evan can go on 30 rides
What is the mean of the data 25, 27, 24, 26, 40 and what is the median
Answer:
mean is = 28.4
median is = 26
Step-by-step explanation:
mean- average
( 25+ 27+ 24+ 26+ 40 )/5 = 28.4
median- middle
25, 27, 24, 26, 40
{ rearrange }
24, 25, 26, 27, 40
the middle number is 26

Answer: yes
Step-by-step explanation:
Answer:
Yes, he has enough money to get his things.
Step-by-step explanation:
3 (the amount of grass seed bags he's buying) x 23 (how many dollars it costs) = 69
3 (the amount of flower pots he's buying) x 15 (how many dollars it costs) = 45
69 + 45 = 114
He will have $6 left over his purchases.
