15 points help me please. show steps!!
Answers
Answer:
12 mph & 4 mph
Step-by-step explanation:
Let s and s - 8 be the speed of Caitlin going on her friend and her speed on her way home respectively.
Distance = Speed × Time
Distance/Speed = Time
9/s + 9/(s - 8) = 3
9(s - 8) + 9s = 3s(s - 8)
9s - 72 + 9s = 3s² - 24s
3s² - 42s + 72 = 0
s² - 14s + 24 = 0
(s - 2)(s - 12) = 0
s - 2 = 0
s = 2
s - 12 = 0
s = 12
If s = 2, then s - 8 = - 6 < 0. We want s and s - 8 to be positive so s = 12 mph. It follows that her speed on her way home is 4 mph.
The table represents the height of a ball thrown up from the roof of a building, h(t), in meters, t seconds after it is thrown upward.

Which statements are true? Check all that apply.
The ball is at the same height as the building between 8 and 10 seconds after it is thrown.
The height of the ball decreases and then increases.
The ball reaches its maximum height about 4 seconds after it is thrown
The ball hits the ground between 8 and 10 seconds after it is thrown.

Step-by-step explanation:
You are the operations manager for an airline and you are considering a higher fare level for passengers in aisle seats. How many randomly selected air passengers must you survey? Assume that you want to be 95% confident that the sample percentage is within 4.2 percentage points of the true population percentage.
Answers
Answer:
545 randomly selected air passengers must be surveyed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
Assume that you want to be 95% confident that the sample percentage is within 4.2 percentage points of the true population percentage.
We dont know the true proportion, so we use [tex]\pi = 0.5[/tex], which is when the largest sample size will be needed. We have to find n for which [tex]M = 0.042[/tex]. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.042 = 1.96\sqrt{\frac{0.5*0.5}{n}}[/tex]
[tex]0.042\sqrt{n} = 1.96*0.5[/tex]
[tex]\sqrt{n} = \frac{1.96*0.5}{0.042}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96*0.5}{0.042})^2[/tex]
[tex]n = 544.4[/tex]

A truck like the one shown delivers a load of gasoline to a gas station 3 times a week. The storage tank at the gas station holds 9 loads of fuel. How much more gas does the storage tank hold than the truck.
The truck hauls 2,700 gallons.
Answers
Answer:
21,600 gallons
Step-by-step explanation:
The truck hauls 2,700 gallons.
Given :
A truck load of gasoline = 2700 gallons
Capacity of storage tank = 9 loads
Gallons of fuel which storage tank can take :
9 loads
1 load = 2700 gallons
9 * 2700 gallons
= 24300 gallons
Hence, the storage tank holds (9 - 1) = 8 more loads of gasoline than the truck :
24300 gallons - 2700 gallons = 21600 gallons

Answer:
The speed of the train is 560 MPH.
Step-by-step explanation:
The car's speed can be detemined by Distance / Time. This would mean we would have to do 224 / 4, which would equal 56.
Now, all we have to do is mulitply 56 by 10. This would equal 560.

A patient has an illness that typically lasts about 24 hours. The temperature, T, in degrees Fahrenheit, of the patient t hours after the illness begins is given by:T(t) = -0.02t^2 +0.4968 +98.
a. When does the patient's temperature reach its maximum value
b. What is the patient's maximum temperature during illness
Answers
Step-by-step explanation:
Given that,
The temperature, T, in degrees Fahrenheit, of the patient t hours after the illness begins is given by:
[tex]T(t)=-0.02t^2 +0.4968 t+98[/tex] ...(1)
(a) We need to find when does the patient's temperature reach its maximum value.
For maximum value.
Put dT(t)/dt = 0
[tex]\dfrac{d(T(t)}{dt}=\dfrac{d}{dt}(-0.02t^2 +0.4968t +98)\\\\=-0.04t+0.4968\\\\-0.04t+0.4968=0\\\\t=12.42\ h[/tex]
(b) Put t = 12.42 in equation (1) :
[tex]T(12.42)=-0.02(12.42)^2 +0.4968 (12.42)+98\\\\=101.08^{\circ} F[/tex]
Hence, this is the required solution.

Answer:
n(x) = g(f(h(x)))
Step-by-step explanation:
Given
[tex]f(x) = x^3[/tex]
[tex]g(x) = x-7[/tex]
[tex]h(x) = x + 2[/tex]
Required
Which function represents [tex]n(x) = (x + 2)^3 - 7[/tex]
Start by solving for f(h(x)):
Given that:
[tex]f(x) = x^3[/tex] and [tex]h(x) = x + 2[/tex]
Substitute x + 2 for the x in f(x)
[tex]f(h(x)) = (x + 2)^3[/tex]
Next, solve for g(f(h(x)))
Given that:
[tex]g(x) = x-7[/tex] and [tex]f(h(x)) = (x + 2)^3[/tex]
Substitute (x + 2)^3 for the x in g(x)
[tex]g(f(h(x))) = (x + 2)^3 - 7[/tex]
Recall that:
[tex]n(x) = (x + 2)^3 - 7[/tex]
Hence:
[tex]n(x) = g(f(h(x))) = (x + 2)^3 - 7[/tex]
