Answer:
y = 1/4x^1 -x -4
Step-by-step explanation:
Same question as previous parts. The working is identical, using different numbers.
Focus-vertex distance is (y-difference) p = -4-(-5) = 1. Vertex is (h, k) = (2, -5). Putting these values into the vertex form and expanding to standard form, you get ...
y = (1/(4p))(x -h)^2 +k
y = 1/4(x -2)^2 -5 . . . . . . . . fill in the values for p, h, k
y = 1/4(x^2 -4x +4) -5 . . . . expand the square
y = 1/4x^2 -x +1 -5 . . . . . . . use the distributive property to eliminate parens
y = 1/4x^1 -x -4 . . . . . . . . . collect terms

A grocery store sells a bag of 7 oranges for $3.08. What is the cost of oranges, in dollars per orange
Answers
Answer:
$0.44 each
Step-by-step explanation:
3.08/7 = 0.44
The required cost in dollars per orange is $0.44.
Given that,
A grocery store sells a bag of 7 oranges for $3.08. What is the cost of oranges, in dollars per orange is to be determined.
The ratio can be described as the proportion of the fraction of one amount towards others. e.g.- water in milk.
What is arithmetic?In mathematics, it deals with a number of functions according to the statements.
here,
Let the cost of 1 orange = $x
The grocery store sells a bag of 7 oranges for $3.08.
So for 1 orange,
x = 3.08 / 7
x = $ 0.44
Thus, the required cost in dollars per orange is $0.44.

· Amanda has $210 in her school lunch account. She spends $35 each week on school lunches. The
equation a = 210 - 35w represents the total amount in Amanda's school lunch account a for w
weeks of purchasing lunches.
Answers
Answer:
(See step-by-step)
Step-by-step explanation:
Let’s start by making A-(X) and W-(Y). So, when substituting the variables you get x=210-35y. When x=0, the answer to the equation is 6. So, the y-intercept (when x=0) is 6 or (0,6). When y=0, the answer to the equation/x-intercept(y=0) is 210 or (210,0). The graph itself looks like the image included.
The domain, realistically, is x>=0 however on the graph itself, the domain is x= All Real Numbers. The range realistically is y>=0, but on the graph it is also All Real Numbers.
The x-intercept is the account when no weeks have passed and no money is lost (210) and the y-intercept is the maximum amount of weeks before there is no more money in the account (6).

A boat traveled 225 miles downstream and back. The trip downstream took 9 hours. The trip
back took 45 hours. Find the speed of the boat in still water and the speed of the current.
Answers
Answer:
30 hrs
Step-by-step explanation:
Downstream. In water, the direction along the stream is called downstream.
Upstream. In water, the direction against the stream is called upstream. Let the speed of a boat in still water be u km/hr and the speed of the stream be v km/hr, then. Speed downstream = (u + v) km/hr. Speed upstream = (u - v) km/hr

What is the weight of a 32 kg child
Answers
Answer:
32000 grams
Step-by-step explanation:
The weight of a 32 kg child in pounds is 70.56 pounds.
What is Measurement unit?
A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.
Given that;
The weight of baby = 32 kg
Now,
Since, 1 kg = 2.205 pounds
So, We convert the weight of baby from kg to pounds as;
1 kg = 2.205 pounds
32 kg = 32 x 2.205 pounds
= 70.56 pounds.
Thus, The weight of a 32 kg child in pounds is 70.56 pounds.

Step-by-step explanation:
Construct the indicated confidence interval for the difference between population proportions p1 - p2. Assume that the samples are independent and that they have been randomly selected. A marketing survey involves product recognition in New York and California. Of 558 New Yorkers surveyed, 193 knew the product while 196 out of 614 Californians knew the product. Construct a 99% confidence interval for the difference between the two population proportions.
Answers
Answer:
-0.0423≤p≤0.0977
Step-by-step explanation:
The margin error formula is expressed as;
ME = p±√p(1-p)/n
n is the sample size
For the first population proportion p1:
p1 = 193/558 = 0.3469
n1 = 558
p2 = 196/614 = 0.3192
n2 = 614
Taking the difference in the confidence of the proportion
p = p1-p2
p = 0.3469-0.3192
p= 0.0277
Get the margin of error
Margin of error = z*√p(1-p)/n
Margin of error = 2.5758*√0.35(1-0.35)/558 + 2.5758*√0.32(1-0.32)/614
Margin of error = 2.5758*√0.35(0.65)/558 + 2.5758*√0.32(0.68)/614
Margin of error = 2.5758*(0.02019)+2.5758(0.0188)
Margin of error = 0.07
Get the confidence interval
CI = p±ME
CI = (p-ME, p+ME)
CI = (0.0277-0.07, 0.277+0.07)
CI = (-0.0423, 0.0977)
Hence a 99% confidence interval for the difference between the two population proportions is -0.0423≤p≤0.0977
A car rental company charges a flat rate of $19.99 for an SUV in addition to $0.79 per mile driven. Nimer's family rents an SUV from this company and drives from St. Louis to Chicago and back. If the distance from St. Louis to Chicago is 297 miles, how much did Nimer's family's pay for the car rental?
Help this is my finals
Answers
Answer:
Nimer's family paid $489.25 for the car rental
Step-by-step explanation:
Nimer's family rents an SUV from a company that charges a flat rate of $19.99 plus $0.79 per mile driven.
They travel from St. Louis to Chicago and back. The distance between these cities is 297 miles, so they drive 2*297 = 594 miles.
The total charges include a flat fee of $19.99 and the cost of 594 miles:
$19.99 + $0.79 * 594 = $19.99 + $469.26 = $489.25
Nimer's family paid $489.25 for the car rental
