The answer choice which could be the length of side BC is; BC < 12.
Which answer choice could be the length of side BC?It follows from the task content that the possible length of the side BC is to be determined.
Since, the sides given AB and BC both have length sum equal to 12. It follows from the triangle inequalities that the length of the third side must be less than the sum of lengths of the other two sides.

Find the zero of the given polynomial :
[tex]p(x) = {x}^{2} + 1[/tex]
Answer:
x = i, -i
Explanation:
p(x) = x² + 1
To set a polynomial to zero, p(x) = 0.
⇒ x² + 1 = 0
relocate variable
⇒ x² = -1
square root both sides
⇒ x = ±√-1
breakdown
⇒ x = √-1, -√-1
simplify if x = √-a then √a i
⇒ x = i, -i
Answer:
+i , -i
Step-by-step explanation:
Zero of the polynomial:p(x) =0
x² + 1 = 0
x² = -1
Take square root both sides,
[tex]\sf x = \sqrt{-1}\\\\x =\sqrt{i^2}\\[/tex]

One side of a triangle has length $10$, and the triangle has integer perimeter. What is the smallest possible perimeter of the triangle
The smallest possible perimeter of the triangle is 21.
The third important property of triangles is the triangle inequality rule, which states: that the length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference between the lengths of the other two sides.
so let 10 = a
10 < b+c
So a good integer value for b+c would be 11
10 > b-c
If we let b be the bigger of the two 10 and 1 would work for b and c respectively or 7 and 4 or 6 and 5 or 6.5 4.5, etc
10 + 11 = 21.

An error was made when working out this sale price.
The price was reduced by 30% instead of 20%.
Calculate the correct sale price for the football shirt.
The correct sales price for the football shirt is $24.75.
What is the correct sales price?The first step is to determine the initial price of the shirt before the 30% discount was applied:
(1 + 0.3) x 23.80 = $30.94

Answer:
[tex]\huge\boxed{\sf (f+g)(x) = 4x - 1}[/tex]
Step-by-step explanation:
Given functions:f(x) = 3x - 2g(x) = x + 1Solution:Add both functions
(f+g)(x) = 3x - 2 + x + 1
Combine like terms
(f+g)(x) = 3x + x - 2 + 1
(f+g)(x) = 4x - 1
[tex]\rule[225]{225}{2}[/tex]
Answer:
[tex](f+g)(x)=4x-1[/tex]
Step-by-step explanation:
FunctionsFunctions written in equation form usually have several parts:
nameinputMathematical rule/expression that tells what the function does to the input to give an output.So, for instance, [tex]g(x)=x+1[/tex] has a name of "g", has an input of "x", and has a rule that it adds 1 to the input to get the output.
The name of the function should tell what rule to follow (look for the equation with that function name), or it may give some details on what the function does.
Dealing with so many different problems, functions often get a default name of "f", "g", or "h".
If a function is special and/or used commonly, it will sometimes get a special name (like the natural logarithm function "ln").
This functionIn this case, the function is (f+g)(x). The function name means that the result of each function, f and g, will be added together, while using the same input "x" for both functions.
[tex](f+g)(x)=f(x)+g(x)\\=(3x-2)+(x+1)\\=3x+(-2)+x+1\\=4x+(-1)\\=4x-1[/tex]
So, given these two functions for "f" and "g", [tex](f+g)(x)=4x-1[/tex]
A bike store marks up the wholesale cost of all bikes they sell by 30%. calvin wants to buy a bike that has a price log of 123.50. what was the wholesale cost of the bike?
The wholesale cost of the bike is 95.
Wholesale price is the price charged for a product as sold in bulk to large trade or distributor groups as opposed to what is charged to consumers.
The selling price is how much a buyer pays for a product or service.
The profit formula is used to calculate the amount of gain that has been made in a transaction
Profit = Selling Price (S.P.) - Cost Price (C.P.)(here it is the wholesale price)
Given =
Selling Price = 123.50Wholesale price = ?Profit = 30% of wholesale priceSubstituting it in the profit formula we get
0.3 x wholesale price = 123.50 + wholesale price
1.3 x wholesale price = 123.50
Wholesale price = [tex]\frac{123.50}{1.3}[/tex] = 95
Thus the wholesale cost of the bike is 95.

infinitely many
Answer:
C. Infinitely many
Step-by-step explanation:
First, find x.
3(x-2)=22-x
Use distributive property.
3x-6=22-x
Add x to both sides.
4x-6=22
Add 6 to both sides.
4x=28
Divide 4 from both sides.
x=7
Plug in 7 for x into the original equation.
3(7-2)=22-7
3(5)=22-7

For the following exercises, determine whether the relation is a function.
2. {(5, 2), (6, 1), (6, 2), (4, 8)}
Answer:
The given relation {(5,2),(6,1),(6,2),(4,8)} is not a function.
Step-by-step explanation:
The relation {(5,2),(6,1),(6,2),(4,8)} is given.
It is required to determine whether the given relation is a function.
To determine whether the given function is a relation, identify the domain and range and then check whether the given relation is a function.
Step 1 of 1
The given relation is {(5,2),(6,1),(6,2),(4,8)}.
The set of the first components of each ordered pair is called the domain.
From the relation, the domain is {5,6,6,4}.
The set of the second components of each ordered pair is called the range.
From the relation, the range is {2,1,2,8}.
The domain of the function does not have a unique range. So, the given relation is not a function.

To gauge how strongly two variables are related to one another, correlation coefficients are used.
A statistical indicator of the strength of the association between the relative movements of two variables is the correlation coefficient. The values are in the -1.0 to 1.0 range. There was a measurement error in the correlation if the estimated value was larger than 1.0 or lower than -1.0. Perfect negative correlation is shown by a correlation of -1.0, and perfect positive correlation is shown by a correlation of 1.0. A correlation of 0.0 indicates that there is no linear link between the two variables' movements. Finance and investing can benefit from the usage of correlation statistics.

Please help me to solve thiss!!
Answer:
x=11, y=2
Step-by-step explanation:
We can set 1 equal to x-5y and then solve for x. and y.
x = 5y+1
y = x-1/5
We can use this information and plug back in the values for 3y-x or x-5y.
We can set -3 = 3y-x or 1 = x-5y.
To solve for x using -3 = 3y-x we can swap the values of x and y which would make it -3 = 3(x-1/5)-5(x-1/5)+1.
We can do a bit of algebra which would get us x = 11.
Knowing that y = x-1/5 we can plug in 11 for x. y = 11-1/5.
y=2
x=11, y=2

The T statistic does not require any information about the population.
The T - statistic is the ratio of the predictable value of a parameter from its hypothesized value to its standard disputable values.
The T statistic uses the sample variance instead of the population variance.
Since, the T statistic depends on the hypothesized population mean. So in place of the standard deviation of population, size or mean of the population, T-statistic depends on the sample mean, the sample standard deviation and the sample size .
