A driver of a car stopped at a gas station to fill up his gas tank. He looked at his watch, and the time read exactly 3:40 p.m. At this time, he started pumping gas into the tank. At exactly 3:44, the tank was full and he noticed that he had pumped 15.3 gallons. What is the average rate of flow of the gasoline into the gas tank? (Round your answer to one decimal place.)
Step-by-step explanation:
first what is the time
3:40 - 3:44
that is 4 minutes
4 min = 15.3 g
rate per min
we need to get 4 min to 1

List the discontinuities for the function f(x) = cot( 5x/3 ).
Answer:
[tex]x=\frac{3\pi n}{5}[/tex]
Step-by-step explanation:
We know that [tex]cot(\frac{5x}{3})=\frac{cos(\frac{5x}{3})}{sin(\frac{5x}{3})}[/tex], so [tex]cot(\frac{5x}{3})[/tex] is undefined where [tex]sin(\frac{5x}{3})=0[/tex]:
[tex]sin(\frac{5x}{3})=0\\\\\frac{5x}{3}=\pi n\\\\5x=3\pi n\\\\x=\frac{3\pi n}{5}[/tex]
So, the discontinuities for the function [tex]f(x)=cot(\frac{5x}{3})[/tex] are where [tex]x=\frac{3\pi n}{5}[/tex] with [tex]n[/tex] being any integer.

The area of a rectangular field is equal to 300 square meters. Its perimeter is equal to 70 meters. Find the length and width of this rectangle.
Answer:
perimeter L = 35 - w
Step-by-step explanation:
L × W = 300 : area , L is the length and W is the width. 2 L + 2 W = 70 : perimeter L = 35 - w : solve for L (35 - W) × W = 300 : substitute in the area equation W = 15 and L = 20 : solve for W and find L using L = 35 - w.

We must do the first derivative test. Here is the steps:
Step 1: Differentiate the polynomial once
we get
[tex]2 {x}^{2} - 2x - 112[/tex]
Step 2: Set this equal to zero and solve for x.
[tex]2 {x}^{2} - 2x - 112 = 0[/tex]
[tex] {x}^{2} - x - 56 = 0[/tex]
[tex](x - 8)(x + 7) = 0[/tex]
[tex]x = 8[/tex]
[tex]x = - 7[/tex]
The solutions are your critical points.
So our critical points are (8,-7).
Step 3: Plot -7 and 8 on a number line. First, pick a number lesser than -7 and plug plug in the derivative function.
Let use -10.
[tex]( - 10 - 8)( - 10 + 7) = 54[/tex]
Since that number is positive, this means are increasing when (-oo,-7)
Next, pick a number greater than 8. Let use 9.
[tex](9 - 8)(9 + 7) = 16[/tex]
Since that is positive, the interval is increasing whe (8,oo)
C. If we pick a number in between -7 and 8, we will get a negative number which means the function is decreasing on interval (-7,8)

Part A: Is triangle POR similar to triangle PAB? Explain using what you know about triangle similarity (5 points)
Part B: Which line segment on triangle PAB corresponds to line segment QR? Explain your answer. (3 points)
Part C: Which angle on triangle PAB corresponds to angle Q? Explain your answer. (2 points)
Answer:
A: the triangles are similar
B: AB corresponds to QR
C: ∠PAB corresponds to angle Q
Step-by-step explanation:
A line segment parallel to the base of a triangle will create a similar triangle. The AA similarity postulate can be used to conclude that.
__
Part A:The triangles PQR and PAB are similar. This derives from the fact that angle P is in both triangles, and corresponding angles PAB and PQR are congruent. The AA congruence postulate applies.
__
Part B:Based on the similarity statement, segment AB corresponds to segment QR.
__
Part C:Transversal PQ crosses parallel lines AB and QR at points A and Q, respectively. The corresponding angles are PAB and PQR.
g A pharmaceutical manufacturer has been researching new formula to provide quicker relief of minor pains. His laboratories have produced several different formula which he wanted to test. Fifteen people who complained of minor pains were recruited for an experiment. Five were given formula 1, five were given formula 2, and the last five were given formula 3. Each was asked to take the medicine and report (X) the length of time until some relief was felt. Using the results of the output, at 0.05 level of significance, what is the critical value for testing differences in the population mean times for pain relief
Answer:
Step-by-step explanation:
From the question we are told that
The sample size is n = 15
The level of significance is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o:\mu_1 = \mu_2 = \mu_3[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 \ne \mu_2 \ne \mu_3[/tex]
Generally the degree of freedom is mathematically represented as
[tex]df = 5 + 5 + 5 - 3[/tex]
=> [tex]df = 12[/tex]
Generally the critical value of [tex]\alpha = 0.05[/tex] at a degree of freedom of [tex]df = 12[/tex] is

Kelsey bought some roses and tulips.She bought twice as many tulips as roses. Roses cost $5 each. Tulips cost $2 each .Kelsey spent $36 total. How many of each kind of flower did Kelsey buy ?
Answer: 4 roses and 8 tulips.
Step-by-step explanation: Each rose costs $5, so she bought 4 of them, which is $20 so far. Since she already bought 4 roses, she bought twice that amount for tulips, which is 8. Each tulip costs $2, so that's $16. Add both $20 and $16 and you have $36.

Round your answers to at least four decimal places. (a) What proportion of the diameters are less than 24.3 millimeters? (b) What proportion of the diameters are greater than 24.6 millimeters? (c) To meet a certain specification, a ball bearing must have a diameter between 24.2 and 24.5 millimeters. What proportion of the ball bearings meet the specification? Part: 0 / 30 of 3 Parts Complete Part 1 of 3 What proportion of the diameters are less than 24.3 millimeters? The proportion of the diameters that are less than 24.3 millimeters is .
Answer:
Z = x - µ / ∂
= 24.2 – 24.6 / 0.07
=-0.4/ 0.07
= -5.71
Step-by-step explanation:
Solution:
Mean = µ = 24.4mm
Standard deviation = ∂= 0.07 mm
(a) Diameter less than 24.3 mm
P(x < 24.3)
The formula for normalized z value:
Z = x - µ / ∂
= 24.3 - 24.4 / 0.07
= - 0.1 / 0.07
= -1.4286
P(z < -1.428) = 1 – p ( z > -1.428)
= 1 – p( z < 1.42)
=1 – 0.4233
= 0.5767
(b) Diameter greater than 24.6 mm
P( x > 24.6)
The formula for normalized z value:
Z = x - µ / ∂
= 24.3 – 24.6 / 0.07
=-0.3 / 0.07
= - 4.285
P( z > -4.285) = 1 – p(z < -4.285)
= 1 – p ( z > 4.285)
=
(c) Diameter between 24.2 and 24.5 mm.
P(x > 24.5)
Z = x - µ / ∂
= 24.5 – 24.6 / 0.07
=-0.1/ 0.07
= -1.4286
P(z < -1.428) = 1 – p ( z > -1.428)
= 1 – p( z < 1.42)
=1 – 0.4233
= 0.5767
P(x < 24.2)
Z = x - µ / ∂
= 24.2 – 24.6 / 0.07
=-0.4/ 0.07
= -5.71

The function of the amount of money is an illustration of an exponential function
The initial balance of the investment is $700, and the rate is 83.53%
How to interpret the function?The function of the amount of money in the investment is given as:
[tex]A(t) = 700(0.8353)^t[/tex]
The above function is an exponential function, and an exponential function is represented as:
[tex]A(t) = ab^t[/tex]
Where:
a represents the initial value, and b represents the rate.
By comparison, we have:
a = 700
b = 0.8353 = 83.53%
Hence, the initial balance of the investment is $700, and the rate is 83.53%
