HELP HELP HELP!!!!! Mason and Jack are lifting weights. Mason uses a 19-kg bar, increasing the weight by 7 kg on each set. Jack starts with an 18-kg bar and increases by 8 kg on every set. Eventually, Mason and Jack will be lifting the same amount. A. How many sets will they have completed? B. How much weight will they be lifting then?
They will lift the same weight (which is 26 kilograms) after one set.
How many sets will they have completed when they lift the same weight?Mason starts at 19kg bar and adds 7kg after each set, so after x sets, he will be lifting:
M(x) = 19 + 7*x
And Jack starts at 18kg, and after each set adds 8kg, then in this case the linear equation is:
J(x) = 18 + 8*x
They will lift the same weight when:
M(x) = J(x)
19 + 7*x = 18 + 8*x
19 - 18 = 8x - 7x
1 = x
So they will be lifting the same weight after one set, and that is:
J(1) = 18 + 8*1 = 26

The x- intercepts in parabola is (1,0) and (5,0).
What do you mean by parabola?A parabola is a type of symmetrical, U-shaped curve that is a graph of a quadratic function. It is defined by the equation y = ax² + bx + c, where a, b, and c are constants. The shape of the parabola is determined by the value of the coefficient "a". If a > 0, the parabola opens upwards, and if a < 0, the parabola opens downwards.
Parabolas are used in many areas of mathematics and science, including physics, engineering, and economics. For example, they are used to model the trajectory of objects under the influence of gravity, to describe the motion of objects in space, and to analyze the behavior of systems that exhibit parabolic patterns.
The vertex of a parabola is the point that represents the highest or lowest point on the curve, and the axis of symmetry is a line that separates the curve into two congruent halves.
The x-intercepts of a parabola can be found by setting the y-value to 0 and solving for x. In this case, the y-coordinate of the x-intercepts will be 0, so we have:
y = 0
To find the x-intercepts, we can use the information given in the coordinates of the parabola: (1,0), (5,0), and (0,6).
From the coordinates (1,0) and (5,0), we can see that the x-intercepts are at 1 and 5.
From the coordinate (0,6), we can see that the y-intercept is at (0,6).
So, the x-intercepts of the parabola are (1,0) and (5,0).

C. assuming the model is correctly specified, what is the long-run change in the log of sales toward which the series will tend to converge
As per the regression equation, the value of intercept coefficient is 1.5707
Regression is a statistical technique used to determine the relationship between an independent variable and a dependent variable.
In this case, the regression statistics provided in table 6 show the results of estimating the model
=> Δln (Sales t) = b0 + b1Δln (Sales t −1) + εt,
where Δln (Sales t) is the change in the natural log of sales for Cisco Systems quarterly observations from 3Q:1991 to 4Q:2000.
The R-squared value of 0.0661 indicates that only about 6.61% of the variation in the change in the log of sales can be explained by the change in the log of sales from the previous quarter.
The standard error of 0.4698 indicates the average deviation between the actual and predicted change in the log of sales.
If the results show that the specification is correct, then the long-run change in the log of sales toward which the series will tend to converge can be determined by the intercept coefficient, which in this case is 1.5707.

three strangers meet at a taxi stand and decide to share a cab to cut down the cost. each has a different destination but all are heading in more-or-less the same direction. bob is traveling 10 miles, sally is traveling 20 miles, and mike is traveling 30 miles. if the taxi costs $2 per mile, how much should each contribute to the total fare? what do you think is the most common answer to this question?
The most common answer to this question is that people would suggest splitting the fare equally i.e. each person contributes $40.
Each stranger should contribute to the total fare based on the distance traveled, so the fare would be divided as follows -
Bob: 10 miles * $2/mile = $20
Sally: 20 miles * $2/mile = $40
Mike: 30 miles * $2/mile = $60
Total fare: $20 + $40 + $60 = $120
Therefore, each stranger should contribute $120/3 = $40 to the total fare.
The most common answer to this question is that people would suggest splitting the fare equally, i.e. each person contributes $40, regardless of the distance traveled. This is because it is a simpler and fairer solution, as each person benefits from the shared ride and the cost savings, regardless of the distance traveled.

how many distinct initial possible pairings are there for a single-elimination ping-pong tour- nament involving n players that result in distinct tournament brackets, for n = 2, 4, 8?
The number of distinct initial possible pairings for a single-elimination ping-pong tournament with n players that result in distinct tournament brackets is 2^(log2(n) - 1).
What is logarithm ?
The logarithm is the inverse function to exponentiation. That means the logarithm of a number x to the base b is the exponent to which b must be raised, to produce x.
In a single-elimination ping-pong tournament, each player plays one match in each round until a champion is determined. For n players, there are log2(n) rounds in the tournament, and in each round half the players are eliminated.
For n = 2, there is only 1 player left after the first round, so there is only 1 distinct pairing and 1 distinct tournament bracket.
For n = 4, there are 2 players left after the first round, and they play in the final. There are 2 possible pairings for the first round, which result in 2 distinct tournament brackets.
For n = 8, there are 4 players left after the first round, and there are 4 possible pairings for the first round. These pairings result in 4 distinct tournament brackets.
So the number of distinct initial possible pairings for a single-elimination ping-pong tournament with n players that result in distinct tournament brackets is 2^(log2(n) - 1).

find a parametrization of the tangent line to ()=(ln()) −10 10 at the point =1.
The tangent line to the curve y = ln(x) - 10 at the point (1, -9) is parametrized by x = t and y = t - 10
To find the tangent line to the curve y = ln(x) - 10 at the point (1, -9), we need to find a parametrization of the line. We can do this by finding the slope of the tangent line and the point at which the tangent line intersects the y-axis.
First, we find the slope of the tangent line by taking the derivative of the function y = ln(x) - 10 at x = 1:
dy/dx = d/dx ln(x) = 1/x
So, the slope of the tangent line at (1, -9) is m = 1/1 = 1.
Next, we find the y-intercept of the tangent line. This can be found by using the point-slope form of a line:
y - y1 = m(x - x1)
Substituting in the values for m, x1, and y1, we get:
y - (-9) = 1(x - 1)
Simplifying, we find:
y + 9 = x - 1
y = x - 10
So, the y-intercept of the tangent line is -10.
Putting everything together, we find that the parametrization of the tangent line to the curve y = ln(x) - 10 at the point (1, -9) is given by:
x = t
y = x - 10 = t - 10
So, the tangent line to the curve y = ln(x) - 10 at the point (1, -9) is parametrized by x = t and y = t - 10.

Answer: 2 3/4.
Step-by-step explanation: To multiply the mixed numbers, we need to first make them into improper fractions. To make 2 1/5 into an improper fraction, we multiply the whole number 2 by the denominator, 5, and add that to the numerator 1, giving us 11/5. We do the same for 1 1/4, giving us 5/4. 5/4 x 11/5 equals 55/20. 55/20 simplifies to 2 3/4.
In a circle with radius 4, an angle intercepts an arc of length 8\pi8π. Find the angle in radians in simplest form.

m∠1 = 49°, m∠2 = 41°, m∠3 = 41°, m∠ADC = 90°, AB = 6.9, BD = 10, and CE = 5.
How to calculate the angles and lengths for the rectangle.Considering the triangle AEB, angles A and B are base angles of a the isosceles triangle AEB so;
2(m∠ABE) + 98 = 180° {sum of interior angles of a triangle}
m∠ABE = (180 - 98)/2
m∠ABE = 41°
m∠1 = 90° - 41° {complementary angles of a rectangle}
m∠1 = 49°
angles m∠2 and m∠BAC are alternate angles and are equal so;
m∠2 = 41°
m∠ADC is one of the four interior angles of a rectangle so m∠ADC = 90°
Considering the right triangle ∆ABD and the tangent of angle B = 41°, we can solve for the length of AB as follows:
tan 41° = 6/AB {opposite/adjacent}
AB = 6/tan41° {cross multiplication}
AB = 6.9022.
m∠3 and m∠ABD are alternate angles so;
m∠3 = 41°
lines AC and BD are diagonals of the rectangle and they bisect each other, since EB = 5 then;
BD = 2 × 5 = 10
CE = 5
Therefore, the following are the respective measures of angles and lengths of the rectangle ABCD:
m∠1 = 49°, m∠2 = 41°, m∠3 = 41°, m∠ADC = 90°, AB = 6.9, BD = 10, and CE = 5.

Angle α is in quadrant III and angle β is in quadrant IV. If sin α = –5/6 and cos β = 1/2, find cos(α + β).
Answer:
Step-by-step explanation:
The expansion for cos(x+y) is cosx*cosy - sinx*siny. We have sin x and cos y, now we need cosx and siny.
Angle x is in QIII and has a sin ratio of -5/6. Since the hypotenuse will never be negative and sin is opposite over hypotenuse, the side across from the reference angle, aka the height of the triangle, is -5 and the hypotenuse is 6. Using Pythagorean's Theorem we can find the third side:
[tex]6^2=(-5)^2+x^2[/tex] and
[tex]36=25+x^2[/tex] and
[tex]36-25=x^2[/tex] so
x = √11.
We do the same for the other angle y. We have the cos of angle y is 1/2 and since the cos ratio is adjacent over hypotenuse, the side next to the reference angle is 1 and the hypotenuse is 2 and we will find the third side using Pythagorean's Theorem:
[tex]2^2=1^2+y^2[/tex] and
[tex]4=1+y^2[/tex] and
[tex]3=y^2[/tex] so
y = √3.
We already know sinx = -5/6, now we know that cosx = -√11/6.
We already know cosy = 1/2, now we know that siny = -√3/2.
Now we can fill in the expansion for cos(x+y):
[tex](-\frac{\sqrt{11} }{6})(\frac{1}{2})-(-\frac{5}{6})(-\frac{\sqrt{3} }{2})[/tex] Multiplying straight across the top and bottom we get
[tex]-\frac{\sqrt{11} }{12}-\frac{5\sqrt{3} }{12}[/tex] which simplifies to
[tex]\frac{-\sqrt{11}-5\sqrt{3} }{12}[/tex]
And you're done!
