if you know that 7 + 2i is a root of a polynomial function ,what is another root of that same function?
Answer: Another root of the same function is 7-2i.
Step-by-step explanation: Given that 7+2i is a root of a polynomial function.
We are to find the another root of the same function.
We know that
if a complex number a+ib is one of the roots of a polynomial function f(x), then the conjugate a-ib is another root of the same polynomial f(x).
According to the given information, the conjugate of 7+21, that is, 7-2i is another root of the same polynomial function.
Thus, another root of the same function is 7-2i.

Tricia is baking a key lime pie for her friends. She is baking the pie in a pie dish that is 9 inches in diameter. What is the circumference of her pie?
Answer: 28.26 inches
Step-by-step explanation:
We know that the circumference of a circle is given by :-
[tex]\text{Circumference}=\pi d[/tex], where d is the diameter of the circle.
Given: The diameter of pie dish (d)= 9 inches
Then the circumference of the pie dish is given by :_
[tex]\text{Circumference}=\pi (9)\\\\\Rightarrow\text{Circumference}=(3.14)(9)\text{Circumference}=28.26\ inches[/tex]

If Mary deposits $275 in principal at an interest rate of 3.2 percent,how much interest will she earn in one year
Final answer:
Mary would earn $8.80 in interest after one year on her deposit of $275 at an annual interest rate of 3.2%, using the simple interest formula.
Explanation:
To calculate the amount of interest Mary would earn from her deposits of $275 at an annual interest rate of 3.2%, we can use the formula for simple interest, which is:
Interest = Principal × rate × time
In this case, Mary's principal is $275, the rate is 3.2% (or 0.032 when expressed as a decimal), and the time is 1 year. Plugging these values into the formula gives us:
Interest = $275 × 0.032 × 1
Interest = $8.80
Therefore, Mary would earn $8.80 in interest after one year.
In Andrew’s Furniture Shop, he builds bookshelves and tables. Each type of furniture takes him about the same time to make. He figures he has time to make, at most, 25 pieces of furniture by this Saturday. The materials for each bookshelf cost him $20.00 and the materials for each table cost him $45.00. He has $675.00 to spend on materials. Andrew makes a profit of $60.00 on each bookshelf and a profit of $100.00 for each table. How many of each piece of furniture should Andrew make to maximize profit? A. define variables B. Write the constraint inequalities that represent the situation, and explain what each of the inequalities represents. (You should have four inequalities.) C. What are the vertices of the feasible region?
We have defined two variables, bookshelves (b) and tables (t), to reflect the number of each that Andrew can make. The constraints representing time and cost are given by two inequalities and these produce a feasible region of possible combinations of bookshelves and tables. Within this region, Andrew can determine the combination that gives maximum profit.
Explanation:Let's define the variables: Let's say 'b' is the number of bookshelves Andrew makes and 't' is the number of tables he makes.
B. The constraint inequalities are: b + t <= 25 due to the time constraint, and 20b + 45t <= 675 due to the cost constraint. These inequalities represent the limit on the number of pieces he can make due to time and the limit due to money available to buy materials.
C. In this system of inequalities, the feasible region would be determined by finding the intersecting points (vertices) of our inequalities. The feasible region is the set of all points that satisfy all the constraints of the problem.
To ascertain the maximum profits, Andrew should calculate his profit for each possible combination of bookshelves and tables within the feasible region to find the combination with the maximum profit.

Pedro was simplifying four over seven divided by five over eight. and his work is shown below. Identify where he made his error. Original problem: four over seven divided by five over eight. Step 1: four over seven multiplied by eight over five . Step 2: four times five over seven times eight. Step 3: twenty over fifty-six. Step 4: five over fourteen.
Answer: it's the 2nd step
Pedro made an error in step 2, he crossed multiplied instead of multiplying.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have:
Pedro was simplifying four over seven divided by five over eight.
= (4/7)/(5/8)
= (4/7)x(8/5)
= 32/35
In Step 2 Pedro made mistake, he crossed multiplied instead of multiplying the numerators, and then the denominators.
Thus, Pedro made an error in step 2, he crossed multiplied instead of multiplying.

(6.03) what is the coefficient of the variable in the expression 6-4x-8+2
A group of children each rode a horse to the bottom of the canyon. They had 20 eyes and 30 legs between them, how many horses were there
You can calculate that, since all children and horses have two eyes, and that children have two legs and horses have four, and the total number of eyes is 20 and the total number of legs is 30, there were 5 children and 5 horses.
Explanation:This problem can be solved using basic algebra. We need to count the numberOfChildren and numberOfHorses in a manner where each child and each horse contribute two eyes and with each child having two legs while each horse has four legs.
Let's make two assumptions:
numberOfChildren = number of children numberOfHorses = number of horsesSo, we can write two equations according to the question:
The total number of eyes = 20 (which implies that numberOfChildren + numberOfHorses = 10, because each creature, whether child or horse, has two eyes)The total number of legs = 30 (which implies that 2*numberOfChildren + 4*numberOfHorses = 30, as each child has two legs and each horse has four)By solving these two equations, we find that the numberOfChildren = 5 and numberOfHorses = 5.

How many times larger is the value 0.75 than the value 0.0075? Please show how to solve the problem.
The value 0.75 is 100 times larger than the value 0.0075.
To solve the problem, we need to determine how many times larger 0.75 is compared to 0.0075. This can be done by dividing the larger number by the smaller number and then simplifying the result.
First, write both numbers as fractions to make the division easier:
[tex]\[ 0.75 = \frac{75}{100} \][/tex]
[tex]\[ 0.0075 = \frac{75}{10000} \][/tex]
Now, divide the fraction representing 0.75 by the fraction representing 0.0075:
[tex]\[ \frac{0.75}{0.0075} = \frac{\frac{75}{100}}{\frac{75}{10000}} \][/tex]
When dividing fractions, we multiply the first fraction by the reciprocal of the second fraction:
[tex]\[ \frac{\frac{75}{100}}{\frac{75}{10000}} = \frac{75}{100} \times \frac{10000}{75} \][/tex]
The 75s in the numerator and denominator cancel out:
[tex]\[ \frac{75}{100} \times \frac{10000}{75} = \frac{10000}{100} \][/tex]
Now, simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which in this case is 100:
[tex]\[ \frac{10000}{100} = \frac{100 \times 100}{100} = 100 \][/tex]
