Answer: (A) [tex]A=300l-l^{2}[/tex]
(B) Length varies between 1 and 150
(C) Largest area is 22500ft²
Step-by-step explanation: Suppose length is l and width is w.
The rectangular garden has perimeter of 600ft, which is mathematically represented as
[tex]2l+2w=600[/tex]
Area of a rectangle is calculated as
[tex]A=lw[/tex]
Now, we have a system of equations:
[tex]2l+2w=600[/tex]
[tex]A=lw[/tex]
Isolate w, so we have l:
[tex]2w=600-2l[/tex]
w = 300 - l
Substitute in the area equation:
A = l(300 - l)
A = 300l - l²
(A) Function of area in terms of length is given by A = 300l - l²
(B) The practical domain for this function is values between 1 and 150.
(C) For the largest area, we need to determine the largest garden possible. For that, we take first derivative of the function:
A' = 300 - 2l
Find the values of l when A'=0:
300 - 2l = 0
2l = 300
l = 150
Replace l in the equation:
w = 300 - 150
w = 150
Now, calculate the largest area:
A = 150*150
A = 22500
The largest area the fence can enclose is 22500ft².

Step-by-step explanation:
Verify experimentally that the angle opposite to the longer side is greater than
the angle opposite to the shorter side in any triangle (at least two figures are
necessary)
Answer:
If two sides of a triangle are unequal, the angle opposite to the longer side is larger (or greater). You may prove this theorem by taking a point P on BC such that CA = CP.
Step-by-step explanation:
That's how you can prove which side is bigger

If you made $125 in 10 hours , how many hours would you take to have to work to earn 550$
Answer:
44 hours
Step-by-step explanation:
If you set up a proportion 10/125= x/550. Then you cross multiply and get 125x=5500 and divide by 125. Now you have x=44

Which relationships would most likely be causal? Select two options.
a positive correlation between the number of homework assignments completed and the grade on the exam
a positive correlation between the temperature in a canyon in the early spring and the number of snakes seen by
hikers
a positive correlation between a child's shoe size and reading speed
a negative correlation between the time a glass of ice water sits on the counter and its temperature
a positive correlation between the number of students attending football games and the number of games that are
won
Answer:
A and B
Step-by-step explanation:
The relationships that are most likely to be causal are:
A positive correlation between the number of homework assignments completed and the grade on the examA positive correlation between the temperature in a canyon in the early spring and the number of snakes seen by hikers.When are relationships causal?A relationship is causal when one variable has a direct effect on another variable. For example, the number of assignments completed would have an effect on the grade on an exam because as a students compeletes his assingment he becomes more familiar with the course.
Positive correlation means that the two variables have a positive relationship with each other. If one of the variable increases, the other vairable increases.

1 over 3 , 3 over 4 ,4 over 7 , 7 over 11, 11over 8 .... (i)one termof this sequence is p over q . Find the term of p and q , the next term in this sequence . Find the 6th term of this sequence 1).... 2).....
Answer:
Next term will be the 6th term i.e. a₆ will be:
a₆ = 14/11Here:
p = numerator = 14q = denominator = 11Step-by-step explanation:
Given the sequence
[tex]\frac{1}{3},\:\frac{3}{4},\:\frac{4}{7},\:\frac{7}{11},\:\frac{11}{8},...[/tex]
First of all the terms of the sequence are in p/q form, where p is the numerator and q is the denominator.
As the fifth term of the sequence is:
a₅ = 11/8
From the given sequence it is clear that the numerator is changing by 3 units and the denominator is also changing by 3 units.
Thus,
The next term will be the 6th term i.e. a₆ will be:
a₆ = 14/11Here:
p = numerator = 14q = denominator = 11!!EASY!! look at the picture
