Miriam buys the chair shown. The tax rate is . How much was the tax on the chair?
The tax on the chair is $7.50.
What is a tax?A tax is a mandatory financial charge or other sort of levy imposed by a governmental entity on a taxpayer in order to fund government spending and related public expenses.
The tax rate is the ratio at which a firm or individual is taxed in a tax system. A tax rate can be presented in numerous ways: statutory, average, marginal, and effective.
Let the cost of the chair be $150 and the assumed tax rate be 5%.
In this case, the tax on the chair will be:
= Tax rate × Cost of chair
= 5% × $150
= 0.05 × $150

I need help graphing this piecewise function!
The piecewise function on the graph is,
f(x) = { 1 -3x ; if x ≤ 2
{ 4-x ; if x > 2
The graph of a piecewise function is given. The left function is defined on the interval x ≤ 2 and the right function is defined on the interval x > 2.
To find the functions we need two points on each function since both functions are straight lines.
First we will find the left function defined on x ≤ 2.
So the two points are (x₁, y₁) = (0,1) and (x₂, y₂) = (2, -5).
Now slope of the left function, m₁ = (y₂ - y₁)/(x₂ - x₁)
= -5 - 1/2 - 0
= -6/2
= -3
So the equation of the left function is,
y - y₁ = m(x-x₁)
⇒ y - 1 = -3(x-0)
⇒ y = 1 -3x
Thus the left function is f(x) = 1 -3x
Consider the right function.
The two points on the graph of the right function are (x₁, y₁) = (4,0) and (x₂, y₂) = (6, -2).
So slope of the second function, m₂ = (y₂ - y₁)/(x₂ - x₁)
= -2 - 0/6-4
= -2/2
= -1
Now equation for the right function is,
y - y₁ = m(x-x₁)
⇒ y - 0 = -1(x-4)
⇒ y = 4 -x
So the right function is f(x) = 4-x
Hence the piecewise function is,
f(x) = { 1 -3x ; if x ≤ 2
{ 4-x ; if x > 2

during the winter olympics the us curling team scored 2 points more than the canadian team. the canadian curling team scored 4 points more than the norwegian team. altogether the three teams scored a total of 208 point. how many points did the canadian team scored?
Answer:
70 points
Step-by-step explanation:
u = US points
c = Canadian points
n = Norwegian points
u = c + 2
n = c - 4
208 = u + c + n
208 = ( c + 2 ) + c + ( c - 4 ) = 3c - 2
Isolate c:
208 = 3c - 2
210 = 3c
c = 70
what is the sum?17.34 8.03+0.009
In order to add these numbers, first let's write all of them with the same number of decimal places:
17.34 = 17.340
8.03 = 8.030
0.009 = 0.009.
Then, let's add all algarisms that are in the same position in each number:
0 + 0 + 9 = 9
4 + 3 + 0 = 7
3 + 0 + 0 = 3
7 + 8 + 0 = 15 (5 plus 1 to next algarism)
1 + 0 + 0 (+ 1) = 2
So the final result is 25.379.
1/6 (x-3) = 1/3 (x+2)
The value of x in the equation given as 1/6(x - 3) = 1/3(x + 2) is 7
How to evaluate the equation?The equation is given as
1/6(x - 3) = 1/3(x + 2)
From the question, we can see that the equation is a linear equation with one variable
As a general rule: linear equations are equations that have constant average rates of change.
We start by multiplying both sides of the equation by 6
So, we have the following equation
6 * 1/6(x - 3) = 1/3(x + 2) * 6
Next, we evaluate the products
So, we have the following equation
x - 3 = 2x + 4
Next, we collect the like terms
So, we have the following equation
2x - x = 3 + 4
Evaluate the like terms in the above equation
x = 7
This means that the solution of the equation is 7

What are square roots?
The opposite of squaring an integer is finding its square root. The result of multiplying a number by itself yields its square value, whereas the square root of a number may be found by looking for a number that, when squared, yields the original value. It follows that a, a = b if "a" is the square root of "b." Every integer has two square roots, one of a positive value and one of a negative value because the square of any number is always a positive number. For instance, the square roots of 4 are both 2 and -2. However, the square root of a number is typically only expressed as the positive value.
The value of a number's power 1/2 is the number's square root. It is the number whose product by itself yields the original number, to put it another way. It is symbolized by the character "." The number behind the square root sign is referred to as the radicand, whereas the square root symbol itself is known as a radical.

The management of the UNICO department store has decided to enclose a 903 ft2 area outside the building for displaying potted plants and flowers. One side will be formed by the external wall of the store, two sides will be constructed of pine boards, and the fourth side will be made of galvanized steel fencing. If the pine board fencing costs $7/running foot and the steel fencing costs $4/running foot, determine the dimensions of the enclosure that can be erected at minimum cost.
The dimensions of the enclosure that can be erected at minimum cost are 21.25 feet by 42.50 feet
How to determine the dimensions of the enclosure that guarantees the minimum costFrom the question, the given parameters are
Area = 903 square feet
Shape = rectangle
From the question, we understand that:
One side of the area would be enclosed by the external wall of the store
If the dimensions of the area are Length (L) and Width (W), then we have
Area = LW
Perimeter = 2L + W
Rewrite as
A = LW
P = 2L + W
Substitute 903 for A in A = LW
LW = 903
Make W the subject
W = 903/L
Substitute W = 903/L in P = 2L + W
P = 2L + 903/L
Differentiate the equation
So, we have
P' = 2 - 903/L²
Set to 0
2 - 903/L² = 0
So, we have
903/L² = 2
This gives
L² = 903/2
Divide
L² = 451.5
Take the square roots
L = 21.25
Substitute L = 21.25 in W = 903/L
W = 903/21.25
Evaluate
W = 42.50
Hence, the dimensions of the enclosure are 21.25 feet by 42.50 feet

8. (15 pts) Explain clearly why Graph A IS a function, while Graph B is NOT a function. (Youcan indicate where the graphs pass or fail and reference that in your explanation)
We can see two graphs and we need to determine the reason why graph A IS a function, and graph B is NOT a function.
To achieve that, we can proceed as follows:
1. A function is a relation in which for each element of the domain we have only (exactly) one element of the range.
2. The domain of a function is the values for x for which the function is defined, and the range is those values for y that result when the function takes values for x and after following the rule of the function (the values for which the function is defined).
3. To determine if a graph is a function, we can use the vertical line test. Given the above definitions, this test tells us that if a vertical line passes through a graph at more than a point, then the relation is NOT a function.
4. Now we can use the Vertical Line Test on each graph as follows:
Graph A:As we can see from the graph, the vertical line passes through only one point (one value for y associated to x). We can see that the open circle indicates that the function is not defined for the value while the solid circle indicates that the function is defined for that value.
For instance, for x = -1 the value of the function is y = 0 (and not y = -1 - see the open circle). We have a similar case for x = 1 (y = 1) (not y = 0).
Therefore, graph A IS a function.
Graph B
In this case, we can say that the vertical line passes through more than one point in most of the values. However, we can say that there are some values where the line passes through one point - from x = -3 to x = -2 (included) -, and for values greater than 2 (x>2).
However, since the vertical line test indicates that the line passes through more than a point (there are more than a value, y, for each x) then Graph B is NOT a function.
Therefore, in summary, we can say that using the method of the vertical line test, Graph A IS a function, while Graph B is NOT a function.
