Answer:
Step-by-step explanation:
Let A = Adam, B = Betty
Adam and Betty purchased a printer together for $258.
This means we can say A + B = 258.
We are also told Adam paid $18 less than twice Betty.
You can write this as:
Adam = 2 x Betty - 18
A = 2B - 18
Substitute "A" into the A + B equation and you get:
A + B = 258
2B - 18 + B = 258
3B - 18 = 258
Add 18 to both sides.
3B = 258 + 18
3B = 276
Divide both sides by 3 to find B
B = 276/3 = 92 (This means Betty paid $92).
Since the total that they paid together was $258.
This means Adam pays the Total - How much Betty paid
Adam = 258 - 92 = $166
Adam pays $166 for the printer.
Given that,
adam and betty purchased a printer together for $258. If adam paid $18 less than twice betty, how much money did Adam pay for the printer is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
What is the equation?The equation is the relationship between variables and represented as y = ax +b is an example of a polynomial equation.
x + y = 258 - - - - -(1)
x = 2y - 18 - - - - -- - (2)
2y - 18 + y = 258
3y = 276
y = $92
Now, put y in equation 2
x = 2 * 92 - 18
x = $166
Thus, Adam pays $166 for the printer.

Answer:
On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 49) and (0, 100).
Which is the graph of the given function?
Here we have the exponential decay:
f(x) = 100*(0.7)^x
So, as x increases, y will tend to zero (because this is a decay, the number with the exponent x is between zero and 1).
Now, if we evaluate in x = 0 we get:
f(0) = 100*(0.7)^0 = 100
Then it goes through the point (0, 100).
If we evaluate in x = 2, we get:
f(2) = 100*(0.7)^2 = 49
Then it also goes through the point (2, 49).
With all that in mind, the correct option is:
"On a coordinate plane, a curve approaches y = 0 in quadrant 1 and curves up into quadrant 2. It goes through (2, 49) and (0, 100)."

Find the volume of the parallelepiped with one vertex at (−2,−2,−5), and adjacent vertices at (−2,5,−8), (−2,−8,−7), and (−7,−9,−1)
The to find the volume of the parallelepiped is V = |A · B × C| where A, B, and C are vectors representing three adjacent sides of the parallelepiped and | | denotes the magnitude of the cross product of two vectors.
The cross product of two vectors is a vector that is perpendicular to both the vectors, and its magnitude is equal to the product of the magnitudes of the two vectors multiplied by the sine of the angle between the two vectors he three adjacent sides of the parallelepiped can be represented by the vectors v1, v2, and v3, and these vectors can be found by subtracting the coordinates of the vertices
:v1 = (-2, 5, -8) - (-2, -2, -5)
= (0, 7, -3)v2 = (-2, -8, -7) - (-2, -2, -5)
= (0, -6, -2)v3 = (-7, -9, -1) - (-2, -2, -5)
= (-5, -7, 4)
Using the formula V = |A · B × C|, we can find the volume of the parallelepiped as follows:
V = |v1 · (v2 × v3)|
where v2 × v3 is the cross product of vectors v2 and v3, and v1 · (v2 × v3) is the dot product of vector v1 and the cross product v2 × v3.Using the determinant formula for the cross-product, we can find that:
v2 × v3
= (-6)(4)i + (-2)(5)j + (-6)(-7)k
= -48i - 10j + 42k

Consider a variant of the hamburger and figs example from class. Rachel has $50 in income, the price per hamburger is $3 and the price per bag of figs is $2. a) Write out an expression for Rachel's budget line. Sketch a graph, with hamburgers on the x axis. b) Suppose the price of figs increases to $3. Write out the new budget line equation and illustrate in your graph. c) Suppose income is $50, the price per hamburger is $3 and the price per bag of figs is $3. Rachel also receives $10 in cash from a friend. Write out a new budget line equation and illustrate in a graph. d) Suppose income is $50, the price per hamburger is $3 and the price per bag of figs is $3. Instead of cash, Rachel's friend gives her a gift basket containing 3 free bags of figs. Sketch Rachel's new budget line? Has the slope of the budget line changed? Can you write out a new budget line equation?
a. The graph of the budget line would have hamburgers on the x-axis and bags of figs on the y-axis. b. the budget line equation represents Rachel's affordability based on her income and the prices of hamburgers and figs. Changes in prices, income, or additional resources can affect the slope, position, or rotation of the budget line on a graph.
a) Rachel's budget line equation can be written as follows:
Budget = (Price of Hamburger * Quantity of Hamburgers) + (Price of Figs * Quantity of Figs)
Since the price per hamburger is $3 and the price per bag of figs is $2, the equation becomes:
Budget = 3x + 2y
Where x represents the quantity of hamburgers and y represents the quantity of bags of figs. The graph of the budget line would have hamburgers on the x-axis and bags of figs on the y-axis.
b) If the price of figs increases to $3, the new budget line equation becomes:
Budget = 3x + 3y
The graph of the new budget line would show a steeper slope compared to the original budget line. This indicates that the relative price of figs has increased, making them relatively more expensive compared to hamburgers.
c) In this scenario, Rachel has an income of $50, the price per hamburger is $3, the price per bag of figs is $3, and she receives an additional $10 in cash from a friend. The new budget line equation can be written as:
Budget = (3x + 3y) + 10
The graph of the new budget line would shift upward parallel to the original budget line. The additional cash from Rachel's friend increases her purchasing power, allowing her to afford more hamburgers and/or bags of figs.
d) Now, Rachel's friend gives her a gift basket containing 3 free bags of figs. In this case, the budget line equation remains the same as in part c:
Budget = (3x + 3y) + 10
However, since Rachel receives 3 free bags of figs, she can allocate more of her budget towards purchasing hamburgers. This would cause the budget line to rotate outward from the y-intercept, resulting in a flatter slope. The new budget line would reflect Rachel's ability to purchase more hamburgers with the same income and price of figs.
In summary, the budget line equation represents Rachel's affordability based on her income and the prices of hamburgers and figs. Changes in prices, income, or additional resources can affect the slope, position, or rotation of the budget line on a graph.

Step-by-step explanation:
A woman is 5 times as old as her daughter . Two years ago the sum of the squares of their age was 1114. Find their present age
A woman is 5 times as old as her daughter. Two years ago the sum of the squares of their age was 1114. Then the present age of daughter is 7 and the mother's age is 35 respectively.
If x is the age of the girl, then the mother's age is 5x. Two years ago, the girl was x - 2 years old, and the mother was 5x - 2 years old. We know the total of their squares two years ago was 1114, so we can write:
(x - 2)² + (5x - 2)² = 1114 -------(1)
Expanding the squares, we get:
x² - 4x + 4 + 25x² - 20x + 4 = 1114
26x² - 24x - 1106 = 0 ----------(2)
Dividing the equation by 2, which will lead to simplifying the equation as:
13x² - 12x - 553 = 0 ----------(3)
Using the quadratic formula
x = - b ± √(b² -4ac)/ 2a
Using this formula, the value of x can be found. For that we substitute the values of b = -12 , a = 13 & c = -553.
x = -(-12) ± √(-12² - 4*13*-553)/2*13
x = 12 ± √(144)- 28756)/26
After solving the equation we will get x = 7 & x = -6.07
We can disregard the negative solution because we are searching for the age of the daughter. As a result, the girl is about 7 years old, and the mother is about 5 times her age, or about 35 years old. To ensure that our answer is accurate, we can check that the sum of their ages two years ago is indeed 1114:
5² + 33² = 1114
Therefore, we can confirm that the daughter's present age is 7 and age of mother is 35.

an triangle has a angle of 75 degrees, x and y are the missing angles but x is twice y, what are the possibilities of x and y?
Answer:
x = 70°
y = 35°
Step-by-step explanation:
Given one angle of a triangle is 75° and the other two are 'x' and 'y', you want to find the possible values of 'x' and 'y' when x = 2y.
SetupThe angle sum theorem and the given relation give rise to two equations:
75 +x +y = 180
x = 2y
SolutionUsing the second equation to substitute for x in the first equation, we have ...
75 +(2y) +y = 180
3y = 105 . . . . . . . . . subtract 75 and simplify
y = 105/3 = 35
x = 2y = 2(35) = 70
The measures of angles x and y are 70° and 35°, respectively.
In a certain triangle, the measure of angle A is three times as big as the measure of angle C and the measure of angle B is 30 degrees bigger than the measure of angle C. What is the degree measure of angle A
The degree measure of angle A is 90 degrees if the measure of angle A is three times as big as the measure of angle C and the measure of angle B is 30 degrees bigger than the measure of angle C.
Let x be the measure of angle C in degrees.
According to the problem statement, angle A is three times as big as angle C, measuring 3x degrees.
Angle B is 30 degrees bigger than angle C, so its measure is x + 30 degrees.
The sum of the measures of the angles in a triangle is always 180 degrees so that we can write:
A + B + C = 180
Substituting the expressions we found for the angles in terms of x, we get:
3x + (x + 30) + x = 180
Simplifying and solving for x, we get:
5x + 30 = 180
5x = 150
x = 30
Therefore, angle C has a measure of 30 degrees, angle B has an estimate of 30 + 30 = 60 degrees, and angle A has a measure of 3(30) = 90 degrees.
So the degree measure of angle A is 90 degrees.

Find the Principal unit normal for r(t) = sintit cost; + tk Evaluate it at t = Tyz Sketch the situation
We can plot the vector r(t) and the vector N(T) at the given value of t = T.
To find the principal unit normal for the vector-valued function r(t) = sin(t)i + tcos(t)j + tk, we need to compute the derivative of r(t) with respect to t and then normalize it to obtain a unit vector.
First, let's find the derivative of r(t):
r'(t) = cos(t)i + (cos(t) - tsin(t))j + k
Next, we'll normalize the vector r'(t) to obtain the unit vector:
||r'(t)|| = sqrt((cos(t))^2 + (cos(t) - tsin(t))^2 + 1^2)
Now, we can find the principal unit normal vector by dividing r'(t) by its magnitude:
N(t) = r'(t) / ||r'(t)||
Let's evaluate the principal unit normal at t = T:
N(T) = (cos(T)i + (cos(T) - Tsin(T))j + k) / ||r'(T)||
To sketch the situation, we can plot the vector r(t) and the vector N(T) at the given value of t = T.

The normal density curve is symmetric about Group of answer choices An inflection point Its mean The horizontal axis A point located one standard deviation from the mean
The normal density curve is symmetric about its mean, with the highest point at the "mean."
The normal density curve is a continuous probability distribution that is widely used in statistics.
It is symmetric about its mean, which is a measure of central tendency. This means that half of the observations fall below the mean, and half fall above it. The curve is bell-shaped, with the highest point at the mean, and it becomes increasingly flatter as it moves away from the mean. The horizontal axis represents the range of possible values for the variable being measured, and the area under the curve represents the probability of observing a given value. An inflection point is a point where the curve changes direction, from concave upwards to concave downwards or vice versa. It is located one standard deviation away from the mean, and it marks the point where the curve begins to flatten. This point is important because it is used to define the standard deviation, which is a measure of how spread out the observations are from the mean. The standard deviation is used to calculate probabilities and to compare different sets of data.In summary, the normal density curve is symmetric about its mean, with the highest point at the mean. The curve is bell-shaped and becomes increasingly flatter as it moves away from the mean.
