Yes, this classic puzzle can be solved by drawing 4 straight lines that cross through all 9 dots without lifting your pencil off the paper or retracing backwards over lines.
To do this, you must extend your lines beyond the boundaries of the 3x3 grid. Start by drawing a line that connects the top left dot to the bottom right dot, then draw a line from the top right dot to the bottom left dot. Next, draw a line from the top middle dot to the bottom middle dot, and finally, draw a line from the left middle dot to the right middle dot. This solution requires thinking outside the box and extending the lines beyond what may seem like the obvious solution.

A company sells widgets. The amount of profit, y, made by the company, is the selling price of each widget, x, by the given equation. Using this equation, find out what price the widgets should be sold for, to the nearest cent, for the company to make the maximum profit. y = -x^2+ 101x – 900
We want maximum profit, which is the max value of y.
We basically want for which x value, we have y as the maximum.
First,
let's take the derivative of y:
\(\begin{gathered} y=-x^2+101x-900 \\ y^{\prime}=-2x+101 \end{gathered}\)Maximum is when the derivative is equal to 0. So, the x-value when derivative is 0:
\(\begin{gathered} y^{\prime}=-2x+101 \\ 0=-2x+101 \\ 2x=101 \\ x=\frac{101}{2} \\ x=50.5 \end{gathered}\)To get max profit, the widgets should be sold at $50.50

Answer:
y = (3/2)x + 3
Step-by-step explanation:
Comment
The general equation is
y = mx + b
Finding m
The equation for the slope is
m = (y2 - y1)/(x2 - x1)
Givens
y2 = 3
y1 = 0
x2 = 0
x1 = - 2
m = (3 - 0)/(0 - -2)
m = 3 / 2
m = 3/2
Finding b
b is the y intercept which is (0,3)
x = 0
y = 3
3 = 0*3 + b
b = 3
So the equation is
y = (3/2) x + 3

$41,000 worth of furnaces? Use pencil and paper. Suppose sales would double. What would be
true about the commission? Explain without using any calculations,
The commission is $
Answer: $1640
Step-by-step explanation:
Since the salesperson's commission rate is 4%, therefore the commission from the sale of $41,000 worth of furnaces will be calculated as follows:
= 4% × $41000
= 4/100 × $41000
= 0.04 × $41000
= $1640
Therefore, the commission is $1640.

Assume that each year the IRS randomly audits 30% of the tax returns. If a married couple has filed separate returns, answer the following questions. (a) What is the probability that both the husband and the wife will be audited? (b) What is the probability that only one of thern will be audited? (c). What is the probabkity that neither one of them will be audited? (d) What is the probability that at least one of them will be audited?
The problem entails calculating the probability for a scenario in which the IRS audits 30% of tax returns at random and a married pair has filed separate returns. Calculate the chances of both husband and wife being audited, just one of them being audited, neither of them being audited, and at least one of them being audited.
a) Probability that both the husband and the wife will be audited: (0.3)² = 0.09 or 9%
b) Probability that only one of them will be audited:
Probability of the husband being audited and the wife not being audited: (0.3)(0.7) = 0.21 or 21%Probability of the wife being audited and the husband not being audited: (0.7)(0.3) = 0.21 or 21%The probability that only one of them will be audited is the sum of the two probabilities which equals 0.42 or 42%.c) Probability that neither one of them will be audited: (0.7)² = 0.49 or 49%
d) Probability that at least one of them will be audited: This is the complement of the probability that neither one of them will be audited. So, the probability that at least one of them will be audited is 1 - 0.49 = 0.51 or 51%.
The relevant terms in this question are probability and statistics. To solve for the probability of each scenario, we used the formulas for independent probabilities and complements.

Answer:
x = 3/85
Step-by-step explanation:
log2 (6) - log2 (5x) = log2 ( 34)
We can use the properties of logs.
First subtract log2 (6) from each side.
log2 (6) - log2 (5x) - log2 (6) = log2 ( 34)-log2 (6)
- log2 (5x) = log2 ( 34)-log2 (6)
Now we know that log a - log b = log a/b
- log2 (5x) = log2 ( 34/6)
- log2 (5x) = log2 ( 17/3)
Multiply each side by -1
log2 (5x) = -log2 ( 17/3)
We know that -log (a/b) = log ( b/a)
log2 (5x) = log2 ( 3/17)
The terms inside the logs must be the same
5x = 3/17
Divide each side by 5
5x/5 = 3/17 * 1/5
x = 3/85

A spherical balloon is inflated so that its volume is increasing at the rate of 3.9 ft^3/min. How rapidly is the diameter of the balloon increasing when the diameter is 1.7 feet?
The diameter of the balloon is increasing at a rate of approximately 0.47 ft/min when its diameter is 1.7 feet.
To find the rate at which the diameter is increasing, we can use the relationship between the volume and the radius of a sphere. The volume of a sphere is given by the formula V = (4/3)πr^3, where V is the volume and r is the radius (half of the diameter).
We are given that the volume is increasing at a rate of 3.9 ft^3/min. Taking the derivative of the volume equation with respect to time, we have dV/dt = 4πr^2(dr/dt), where dV/dt is the rate of change of volume with respect to time and dr/dt is the rate of change of the radius with respect to time.
Since we are interested in finding the rate of change of the diameter, which is twice the rate of change of the radius, we can rewrite the equation as dV/dt = (4/3)π(2r)(2dr/dt) = (8/3)πr(dr/dt).
Plugging in the given values, we have 3.9 = (8/3)π(0.85)(dr/dt), where the diameter is 1.7 feet and the radius is half of that (0.85 feet). Solving for dr/dt, we find that dr/dt ≈ 0.47 ft/min. Therefore, the diameter of the balloon is increasing at a rate of approximately 0.47 ft/min when the diameter is 1.7 feet.

an airplane is 58 m long. a scale model of the plane is 40.6 cm long.
determine the scale factor used to create the model as a decimal rounded
to the nearest thousandth
If a scale model of the plane is 40.6 cm long, the scale factor used to create the model is approximately 1:142.857 or 0.007 rounded to the nearest thousandth.
To determine the scale factor used to create the model, we need to divide the length of the actual airplane by the length of the model airplane:
58 m / 40.6 cm
To perform this calculation, we need to convert the units so that they match. We can convert 58 m to cm by multiplying by 100:
58 m = 58 × 100 cm = 5800 cm
Now we can divide:
5800 cm / 40.6 cm = 142.857...
Rounding to the nearest thousandth, we get:
142.857... ≈ 142.857
Therefore, the scale factor used to create the model is approximately 1:142.857 or 0.007 rounded to the nearest thousandth.

Two consecutive angles of a parallelogram measure 3x+42 and 9x-18. What are the measures of the angles?
The angles are 81 degrees and 99 degrees
============================================================
Explanation:
Consecutive angles, aka adjacent angles, of a parallelogram always add to 180 degrees. They are considered supplementary.
(angle A)+(angle B) = 180
(3x+42)+(9x-18) = 180
(3x+9x)+(42-18) = 180
12x+24 = 180
12x = 180-24
12x = 156
x = 156/12
x = 13
We can then find the measure of each angle
angle A = 3x+42 = 3*13+42 = 81angle B = 9x-18 = 9*13-18 = 99Then notice that A+B = 81+99 = 180 to confirm the answers.

Mary evaluates goods 1 and 2 according to the following utility function: u(x1,x2 )=3x1 +x2
. For which of the following vectors of prices would Mary only buy good 1 ?
a. p1=3,p2 =2
b. p 1 =10,p2=3
c. p1=4,p2=1
d. p1=15,p2 =4
e. None of the above, since the price of good 1 is larger than the price of good 2
The price vectors a. p₁ = 3 and p₂ = 2, Mary will consume only good 1.
Here we have the Utility function as
U(x₁ , x₂) = 3x₁ + x₂
From the given utility function we can clearly see that these goods are substitutes for each other
Now,
δU/δx₁ = 3
δU/δx₂ = 1
Hence we get the Marginal Rate of Substitution or MRS
\(=- \frac{\delta U/ \delta x_1 }{\delta U/ \delta x_2}\)
= -3
The MRS signifies that for every additional unit of 1, Mary is willing to give up 3 units of good 2
|MRS| = 3
For Mary to only consume good 1, |MRS| > p₁/p₂
Hence here we get the p/p ratio for the 4 price vectors to be
a. 3/2 = 1.5
b. 10/3 = 3.33
c. 4
d. 15.4 = 3.75
Hence we can clearly say that for the price vectors p₁ = 3 and p₂ = 2, Mary will consume only good 1.

altitude, h, be? Round to the
nearest tenth of a mile.
The plane’s altitude will be approximately 6,336 feet when it has flown over 7 miles of ground and climbed at a 9° angle.
What is meant by miles?
Miles are a unit of distance used in the United States and some other countries, equal to 5,280 feet or 1.609 kilometres. Miles are commonly used to measure distances between cities, countries, and other geographical locations.
What is meant by angle?
A geometric shape known as an angle is created by two rays or line segments that have a similar terminal (referred to as the vertex). Angles can be expressed as radians or degrees and are used to describe how lines and shapes are oriented, situated, and related to one another. Angles can be categorised according to their size and shape as acute, right, obtuse, straight, or reflex.
According to the given information
The problem can be solved using trigonometry 1. The altitude of the plane can be calculated using the tangent function as follows: tan(9°) = h/7 h = 7 tan(9°) ≈ 1.2 miles ≈ 6,336 feet
Therefore, the plane’s altitude will be approximately 6,336 feet when it has flown over 7 miles of ground and climbed at a 9° angle.

a soccer team has 13 players. a starting lineup consist of 11 players, one of whom is a goalkeeper and the other 10 regular players (players are interchangeable). how many different starting lineups can the team have?
The soccer team can have 1,716 different starting lineups. The number of ways to choose 1 player out of 13 for the goalkeeper position is given by the combination formula: C(13, 1) = 13.
To calculate the number of different starting lineups, we need to determine the combinations of players that can be chosen for the starting lineup. Since there are 13 players on the team and 11 positions in the starting lineup, we need to choose 1 player for the goalkeeper position and 10 players for the regular positions. Similarly, the number of ways to choose 10 players out of the remaining 12 players for the regular positions is given by the combination formula:
C(12, 10) = 66.
To find the total number of different starting lineups, we multiply the number of choices for the goalkeeper position by the number of choices for the regular positions: 13 * 66 = 858.
However, the order of the players in the lineup doesn't matter, so we need to divide the result by the number of permutations of the 10 regular players: 858 / 10! = 1716. The soccer team can have 1,716 different starting lineups.
