Answer:
The function written in python is as follows
def min(str1,str2):
if str1 < str2:
return str1
else:
return str2
Step-by-step explanation:
This line defines the function min, along with two parameters str1 and str2
def min(str1,str2):
This line checks if str1 is less than str2
if str1 < str2:
If yes, the function returns str1
return str1
If otherwise,
else:
The function returns str2
return str2
Take for instance
str1 = "abc"
str2 = "cba"
The function will return str1 because str1 is less than str2 in the sense that the first letter of str1 (a) is less than the first letter of str2 (c)
According to the Insurance Institute of America, a family of four spends between $400 and $3,800 per year on all types of insurance. Suppose the money spent is uniformly distributed between these amounts. If we select a family at random, what is the probability they spend less than $2,000 per year on insurance per year? (Round your answer to 4 decimal places.)
Answer:
0.471
Step-by-step explanation:
Calculation for the probability that they spend less than $2,000 per year on insurance per year
First step is to find the base
Base =$2,000-$400
=$1,600
Second step is to find the probability using this formula
P=1/b+a×base
Where,
b represents $3,800
a represents $400
base represents $1,600
Let plug in the formula
P=1/$3,800-$400×$1,600
Hence,
P=1×$1,600/$3,800-$400
P=$1,600/$3,400
P=0.471
Therefore the probability that they spend less than $2,000 per year on insurance per year will be 0.471

y = x + 3
y= x2 + 2x-4
A. x+ 3 = x2 + 2x - 4
B. X+ 3 = x2
C. y= (x+3)2 + 2(x + 3) - 4
D. y= x2 + 2x - 4 - (x+3)
Answer:
(A)[tex]x + 3= x^2 + 2x-4[/tex]
Step-by-step explanation:
Given the equations:
[tex]y = x + 3\\y= x^2 + 2x-4[/tex]
Substitution simply means replacing the variable y in the second equation with its equivalent x+3 from the first equation.
Substitution of y into [tex]y=x^2 + 2x-4[/tex] gives us:
[tex]x + 3= x^2 + 2x-4[/tex]
The correct option is A.
After the first 4 quizzes, Ron’s quiz average is an 87. There are two quizzes remaining for the quarter and the maximum score for any individual quiz is 100. What is the minimum grade Ron can score on one of these two quizzes and still score high enough on the other so that the final quiz average of the six quizzes is at least a 90?
Answer:
Minimum = 92 ; maximum =100
Step-by-step explanation:
Total number of quizzes = 6
Number of completed quizzes = 4
Number of quizzes left = 2
Average score on completed quizzes = 87
Target average = 90
Maximum score for any individual quiz = 100
Current total score on the 4 quizzes to obtain an average of 87:
87 * 4 = 348
To obtain an average of 90:
Total score must in the six quizzes must be :
90 * 6 = 540
Therefore total score needed in the remaining 2 quizzes to attain an average of 90:
540 - 348 = 192
Since the highest attainable score is 100:
Maximum score Ron can attain on one quiz = 100
Minimum he can attain in the other = 192 - 100 92 in other to score an average of 90 in the six quizzes.
A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, determine which system of inequality best explains whether the company can build 20 child bikes and 6 adult bikes in the week. (2 points)
Answer:
4 (20) + 6(6) = 120
4(20) + 4 (6) = 100
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations with the information given:
Build time (hours) = 4c + 6a = 120
Test time (hours) = 4c + 4 a = 100
Where c represents the number of child bikes and a represents adult bikes.
So, for 20 child bikes and 6 adult bikes:
4 (20) + 6(6) = 120
4(20) + 4 (6) = 100

Answer:
The correct option is;
The domain is all real numbers and the range is all real numbers greater than or equal to -4
Step-by-step explanation:
A function defines an output given an input and the set of all the possible inputs to a function is the domain of a function such that there is an output, such that the domain is the set of x values which are points on the curve of the function
The set of outputs that are produced from a given input is the range of a function
The given function is f(x) = (x + 2)(x + 6)
From the curve we see that the minimum y-coordinate, f(x), value is at -4, which is the lower bound of the range, while the x-coordinate values, the domain can be seen extending past the graph sheet which from the expression for the function also (f(x) = (x + 2)(x + 6)) indicates that the x values is the set of all real numbers (on the number line)
Therefore, the correct option is;
The domain is all real numbers and the range is all real numbers greater than or equal to -4.
Answer:
The domain is all real numbers and the range is all real numbers greater than or equal to -4

x + 2y = -1
5x - 4y = 16
Put your answer in ordered pair (x, y) DECIMAL form.
Answer:
(x, y) = (2, -1.5)
Step-by-step explanation:
x + 2y = -1
5x - 4y = 16
<=>
(2)x + (2)2y = (2)(-1)
5x - 4y = 16
<=>
2x + 4y = -2
5x - 4y = 16
<=>
7x = 14
<=>
x = 2
(*)x + 2y = -1
=> 2 + 2y = -1
=> 2y = -3
=> y = -1.5
=> (x, y) = (2, -1.5)

What is the measure of ZE, in degrees?
Answer:
B. 84 deg
Step-by-step explanation:
Sides DE and FE are congruent since they both have the same length.
That makes angles D and F congruent.
m<D = m<F = 48
The sum of the measures of the angles of a triangle equals 180 deg.
m<E + m<D + m<F = 180
m<E + 48 + 48 = 180
m<E = 84
John is filling a bathtub that is 12 inches deep. He notices that it takes two minutes to fill the tub with three inches of water. He estimates it will take 10 more minutes for the water to reach the top of the tub if it continues at the same rate. Is he correct?
Answer:
No
Step-by-step explanation:
2 = 3 inches
2x5=10
10 = 3x5 of 15 inches
so no and it would take 8 minutes to fill up the tub
The numbers -1/5 and -5 are 'negative reciprocals.' True or False?
Answer:
False

Find the point-slope equation for the line that passes through the points (-8,-32) and (3,1). Use the first point in your equation.
Hey there! :)
Answer:
y + 32 = 3(x + 8)
Step-by-step explanation:
Begin by finding the slope of the line using the slope formula:
[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Plug in the coordinates of the points into the equation:
[tex]m = \frac{1 - (-32)}{3 - (-8)}[/tex]
Simplify:
[tex]m = \frac{33}{11}[/tex]
m = 3.
Point-slope form is:
y-y₁=m(x-x₁)
Plug in the coordinates of the first point, as well as the slope:
y - (-32) = 3(x - (-8)
y + 32 = 3(x + 8)
Answer: y+32=3(x+8)
Step-by-step explanation:
First you need to find the slope.The slope is the change in y divided by the change in x values.
-32 - 1 = -33
-8 - 3 = -11
-33/-11 = 3 the slope is 3
and in point-slope form is like y-b= m(x-a) where b is a y coordinate and a is the x coordinate.
it could be like y-1=3(x-3) or y+32= 3(x+8)
the illumination due to a source of light varies directly as the strength of the source and inversely as the square of the distance from the source. two sources are 6 meters apart and one of them is 8 times stronger than the other. at what distance from the weaker source on the line segment joining them is the illumination the least
Answer:
Point is at x = 4 m
Step-by-step explanation:
From the question, we can write the formula for intensity as;
I = strength/distance²
Now,
- Let x be the position from the stronger source
- Let k be the strength of the weaker light source
- 8k will be the strength of the stronger light source.
We are told that the two sources are 6 meters apart and one of them is 8 times stronger than the other.
Thus, the total illumination is;
I(x) = (8k/x²) + k/(6 - x)²
Using chain rule to get the critical points, let's find the first derivative and equate to zero;
I'(x) = -16k/x³ + 2k/(6 - x)³ = 0
Adding -16k/x³ to both sides, we have;
2k/(6 - x)³ = 16k/x³
Cross multiply to get;
2kx³ = 16k(6 - x)³
Dividing both sides by 16k to give;
x³/8 = (6 - x)³
Taking cube root of both sides to give;
x/2 = 6 - x
Multiply both sides by 2 to give;
x = 12 - 2x
x + 2x = 12
3x = 12
x = 12/3
x = 4 m

The temperatures of Charleston, South Carolina on May 3rd are recorded in the table below. Determine the equation that models this data.
Answer:
Ok, the first step to see the behavior of this data is doing a graph of it,
So we can see that it looks like an reversed V. (at the bottom of the answer you can see the graph)
Then, we can model this with a piecewise function like:
For the first part we can take the two pairs:
if 11 am is our t = 0h
(0, 85) and (6, 93)
then the linear equation
y = a*t + b
a = (93 - 85)/(6 -0) = 8/6.
and b = 85.
then the linear equation is:
y = (8/6)*t + 85. for 0h ≤ t ≤ 6h
The second part of this equation can be modeled with the points
(6, 93) and (11, 84)
then we have:
y = s*t + c
s = (84 - 93)/(11 - 6) = -7/5
and we can find the value of c as:
93 = (-7/5)*6 + c
93 + (7/5)*6 = 101.4
then this second part is:
y = (-7/5)*t + 101.4 for 6 ≤ t ≤ 11h
then, in conclusion we have:
y = (8/6)*t + 85. for 0h ≤ t ≤ 6h
f(x) =
y = (-7/5)*t + 101.4 for 6 ≤ t ≤ 11h
