Write an equation of a line that passes through the point (4,3) and is perpendicular to the graph of the equation y=−1/3+4
Answer:
Step-by-step explanation:
Hello:
an equation for the line is : y =mx +b (m: is a slope )
perpendicular to the line described by : y = -1/3 x +4
So : product for two slopes = -1 means : m×-1/3=-1
m = 3
now : y = 3 x+b
but this line :
through the point (4,3) : 3 =3(4)+b....... b=-9
conclusion :
the equation is : y =3x -9

one way to test if a graph is a function or not is by doing a?
One way to test if a graph is a function or not is by doing a vertical line test.
The vertical line test is tested by testing if any vertical line is drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function, if there isn't any such line, the graph is a function.
Hope that helps!
Answer:
Vertical line test. (literally what it say)
Step-by-step explanation:
Given a graph, use the vertical line test to determine if the graph represents a function. Inspect the graph to see if any vertical line drawn would intersect the curve more than once.
Therefore you would have x value being the same for several points.

How to find the mean of a data set?
Mean is the ratio of the sum of the values of the data set to the total number of values available in the data set.
Thus, we get;
[tex]\rm Mean = \dfrac{\text{Sum of the observations of the data set}}{\text{Total number of observations}}[/tex]
We are given that;
The data set= {425, 255, 267, 507, 307, 435, 253, 250, 433}
Now,
The five-number summary of a data set consists of the minimum, first quartile (Q1), median, third quartile (Q3), and maximum12.
To find the five-number summary of this data set, follow these steps:
Put the numbers in ascending order: {250, 253, 255, 267, 307, 425, 433, 435, 507}
Find the minimum: The smallest number is 250
Find the maximum: The largest number is 507
Find the median: The middle number is 307
Find Q1: The median of the lower half of the data is 255
Find Q3: The median of the upper half of the data is 435
Therefore, by the mean the answer will be {250, 255, 307, 435, 507}

A bag of chocolates is labeled to contain 0.384 pounds of chocolates. The actual weight of the chocolates is 0.3798 pounds. Are the chocolates heavier or lighter than the weight stated on the label?
Based on the information given the chocolates stated on the label is 0.0042-ounce lighter.
Weight:
Using this formula
Chocolate weight=Current weight-Actual weight
Where:
Current weight=0.384
Actual weight=0.3798
Let plug in the formula
Chocolate weight=0.384-0.3798
Chocolate weight=0.0042 ounce
In conclusion, the chocolates stated on the label are 0.0042-ounce lighter.

A 25-year, $1,000 par value bond has an 8.5% annual coupon. The bond currently sells for $875. If the yield to maturity remains at its current rate, what will the price be 5 years from now?
Given the current yield to maturity of the bond, the price of the bond five years for now is $883.10.
What is the price of the bond five years from now?The first step is to determine the yield to maturity of the bond. The yield to maturity is the return on the bond if the bond is held to matuity.
Yield to matuity can be determined using a financial calculator:
Cash flow in year 0 = -875
Cash flow each year from year 1 to 25 = 85
Cash flow in year 25 = $1000
Yield to matuity = 9.86%
Future price of the bond: (coupon x future price factor) + [FV / (1 + YTM)^n)]
Future price factor = [1 - (1/YTM)^n] / YTM
= [1 - 1/0.0986^20] 0.0986 = 8.595555
[85 x 8.595555 ] + 152.478323 = $883.10

Angle α is drawn on the unit circle in standard position. The terminal side of angle α intersects the unit circle at point (-0.292, 0.956). What is the approximate decimal value of tan(α)?
Using the unit circle, it is found that the approximate decimal value of tan(α) is given by -3.274.
What is the unit circle?For an angle [tex]\alpha[/tex] the unit circle is a circle with radius 1 containing the following set of points: [tex](\cos{\alpha}, \sin{\alpha})[/tex].
In this problem, we have point (-0.292, 0.956), hence [tex]\cos{\alpha} = -0.292, \sin{\alpha} = 0.956[/tex].
Applying the definition of the tangent, we have that:
[tex]\tan{\alpha} = \frac{\sin{\alpha}}{\cos{\alpha}} = \frac{0.956}{-0.292} = -3.274[/tex].
Hence the second option is correct.
