In the back of the maze, you will see two numbers at the start and end points of the maze. Let's call these numbers a and b.

To solve the maze, we need to find the geometric mean of a and b, which is the value that, when multiplied by itself, gives us the product of a and b.

The formula for the geometric mean is:

Geometric Mean = √(a × b)

So, to solve the maze, we need to find the geometric mean of the starting and ending numbers, and then follow the path in the maze that matches that value. This path will lead us to the end of the maze.

Once we find the geometric mean of the starting and ending numbers, we can use a calculator or mental math to simplify the expression and find the value.

What is Trigonometric Functions?

Trigonometry uses six fundamental trigonometric operations. Trigonometric ratios describe these operations. The sine function, cosine function, secant function, co-secant function, tangent function, and co-tangent function are the six fundamental trigonometric functions. The ratio of sides of a right-angled triangle is the basis for trigonometric functions and identities. Using trigonometric formulas, the sine, cosine, tangent, secant, and cotangent values are calculated for the perpendicular side, hypotenuse, and base of a right triangle.

y=tanx

dy/dx = dy/dx = cos x.cos x - sin x(-sin x) / cos² x

⇒ dy/dx = (cos² x + sin² x) / cos² x

⇒ dy/dx = 1 / cos²x

⇒ dy/dx = sec²(x)

Thus, the derivative of y = tan(x) is sec²(x).

Answer:2>x[tex]\geq[/tex]-3

Step-by-step explanation:

when we divide each side with a negative number "<" turns into ">",">" turns into "<" and so on.

we can divide each side with -1, the we get,

2>x[tex]\geq[/tex]-3

[tex]-2 < -x \leq 3 \iff 2 > x \geq -3[/tex]

The possible value of x that is here, a are 8 and 12, when the sum of two number and product is given.

A group of two or more equations that must be solved all at once is known as a system of equations. The values of the variables in a system of equations that make all of the equations in the system true are known as the solutions. Several approaches, including substitution, elimination, and graphing, can be used to solve systems of equations. Several branches of mathematics, science, and engineering employ systems of equations to represent and solve issues that arise in the real world.

Let us suppose the two numbers = a and b.

Thus, from the given statement we have:

a + 2b = 20 (Equation 1)

and

ab ≤ 48 (Equation 2)

Using equation 1:

a = 20 - 2b

Substituting this expression for "a" into Equation 2, we get:

(20 - 2b)(b) ≤ 48

-2b² + 20b - 48 ≤ 0

b² - 10b + 24 ≥ 0

This inequality can be factored as:

(b - 4)(b - 6) ≥ 0

Since we want the product of the two numbers to be less than or equal to 48, both "a" and "b" must be positive.

We only need to consider the values of "b" that make this inequality true:

b ≤ 4 or b ≥ 6

Plug each of these values of "b" back into Equation 1:

When b = 4, we get:

a + 2(4) = 20

a = 12

When b = 6, we get:

a + 2(6) = 20

a = 8

Therefore, the possible values of "a" are 8 and 12.

What is area and volume?

A flat, two-dimensional object's area is the space it takes up in a plane. A three-dimensional object's volume is the area it takes up in space.

We know that

Curved surface area = 2πrh

So, using this we get

⇒Curved surface area = 2 × 3.14 × 14 ×25

⇒Curved surface area = 2,198 square centimeter

Similarly,

Total surface area = 2πr (r + h)

So, using this we get

⇒Total surface area = 2 × 3.14 × 14 (14 + 25)

⇒Total surface area = 2 × 3.14 × 14 (39)

⇒Total surface area = 3,428 square centimeter

Similarly,

Volume = π[tex]r^{2} h[/tex]

Answer:A

Step-by-step explanation:

1) y + (1/2)x = 2

2)-59 - 153i

3)1315 - 62i

4)No real solutions

1) Equation for a line perpendicular to y=2x+3 and passing through the point (4-6)A line perpendicular to y = 2x + 3 would have a slope of -1/2 (the negative reciprocal of 2). To find the equation of the line, we use point-slope form. We substitute the point (4, -6) and the slope of -1/2:We know that the line must pass through the point (4, -6) and be perpendicular to the line y = 2x + 3, so we can write its equation in point-slope form as follows:y - (-6) = (-1/2)(x - 4)y + 6 = (-1/2)x + 2The answer is y + (1/2)x = 2.

2) Multiplying the complex numbers (11-3i)(7-12i)We will be using the FOIL method (first, outer, inner, last) for multiplying two binomials:First, we multiply 11 and 7 to get 77.Then, we multiply 11 and -12i to get -132i.Next, we multiply -3i and 7 to get -21i.Last, we multiply -3i and -12i to get 36i² (remembering that i² is equal to -1).Finally, we combine like terms:77 - 132i - 21i + 36i² = 77 - 153i - 36 = -59 - 153iThe answer is -59 - 153i.

3) Dividing complex numbers (185-72i) divided by (11+10i)To divide complex numbers, we need to multiply the numerator and denominator by the conjugate of the denominator (in which the sign of the imaginary part is changed):We multiply the numerator and denominator by the conjugate of 11 + 10i, which is 11 - 10i in this case, to eliminate the imaginary part from the denominator:(185 - 72i)(11 - 10i) = (185 × 11 - 72i × 11) - (185 × 10i + 72i × 10i) = (2035 - 792i) - (1850i + 720i²)Simplifying, we get:(2035 - 792i) - (1850i + 720i²) = (2035 - 792i) - (1850i + 720(-1)) = (2035 - 792i) - (1850i - 720) = 1315 - 62iThe answer is 1315 - 62i.

4) Solving an equation by completing the square: y² - 6y + 19 = 5First, we isolate the y terms and move the constant to the other side:y² - 6y + 14 = 0Next, we divide both sides by the leading coefficient (1 in this case):y² - 6y = -14To complete the square, we take half the coefficient of y, square it, and add it to both sides. In this case, that's (-6/2)² = 9:y² - 6y + 9 = -5Now, we factor the left-hand side as a perfect square:(y - 3)² = -5Finally, we take the square root of both sides:(y - 3) = ±√(-5)This expression has no real solutions because the square root of a negative number is imaginary. Therefore, the answer is "No real solutions."

Answer: Let's call the number of large boxes purchased "L" and the number of small boxes purchased "S".

From the problem, we know that:

Each small box has 100 nails, so the total number of nails from the small boxes is 100S.

Each large box has 450 nails, so the total number of nails from the large boxes is 450L.

The contractor bought 3 more small boxes than large boxes, so S = L + 3.

The total number of nails purchased is 2500, so 100S + 450L = 2500.

We can use the second equation to solve for one of the variables in terms of the other. For example, we can solve for L:

100S + 450L = 2500

Substituting S = L + 3:

100(L + 3) + 450L = 2500

Expanding the parentheses:

100L + 300 + 450L = 2500

Combining like terms:

550L + 300 = 2500

Subtracting 300 from both sides:

550L = 2200

Dividing both sides by 550:

L = 4

So the contractor purchased 4 large boxes of nails.

We can use the equation S = L + 3 to find the number of small boxes purchased:

S = L + 3 = 4 + 3 = 7

So the contractor purchased 7 small boxes of nails.

Therefore, the contractor purchased 4 large boxes and 7 small boxes of nails.

Answer:

b ≈ 2.636.

Step-by-step explanation:

First, we can simplify both sides of the equation by combining like terms:

2b + 8 - 5b + 3 = -13 + 8b - 5

-3b + 11 = 8b - 18

Next, we can isolate the variable term on one side of the equation by adding 3b to both sides:

-3b + 3b + 11 = 8b - 18 + 3b

11 = 11b - 18

Then, we can isolate the variable term again by adding 18 to both sides:

11 + 18 = 11b - 18 + 18

29 = 11b

Finally, we can solve for b by dividing both sides by 11:

29/11 = b

b ≈ 2.636

Therefore, the solution to the equation is b ≈ 2.636.

Answer:

b = 29/11

Step-by-step explanation:

2b + 8 - 5b + 3 = -13 + 8b - 5

-3b + 11 = -18 + 8b

-11b + 11 = -18

-11b = -29

b = 29/11

Using the Law of Cosines the length of l, to the nearest 10th of a centimeter is 4.6 cm.

To find the length of side l in triangle LMN, we can use the Law of Cosines, which states that c² = a² + b² - 2ab cos(C), where c is the side opposite the angle C.

In this case, we have:

a = 5.9 cm

b = 8.7 cm

C = 163°

First, we need to convert the angle from degrees to radians by multiplying it by π/180:

C = 163° × π/180 = 2.847 radians

Now we can plug in the values into the Law of Cosines:

l² = 5.9² + 8.7² - 2(5.9)(8.7)cos(2.847)

Simplifying the right-hand side:

l² = 68.81 - 60.83 × cos(2.847)

Taking the square root of both sides:

l ≈ 4.6 cm

The p-value is 0.1138 for the given hypothesis.

What exactly is a p-value?

A p-value, or probability value, is a statistical measure that helps to determine the strength of evidence against a null hypothesis in a hypothesis test. In hypothesis testing, a null hypothesis is a statement or assumption about a population parameter that we want to test using sample data. The p-value is the probability of obtaining a test statistic as extreme as, or more extreme than, the observed test statistic, assuming the null hypothesis is true.

Now,

To test the hypothesis,

 we need to perform a hypothesis test using a significance level (α) to determine whether the sample proportion of satisfied customers is significantly different from 0.9.

The null hypothesis (H0) is that the true proportion of satisfied customers is equal to 0.9. The alternative hypothesis (H1) is that the true proportion is not equal to 0.9.

We can use the normal approximation to the binomial distribution to test this hypothesis, since the sample size is large (n = 1000) and both np and n(1-p) are greater than or equal to 10, where p is the true proportion of satisfied customers.

The test statistic is given by:

z = (P - p0) / √(p0(1 - p0) / n)

where p0 is the proportion (0.9), P is the sample proportion (850/1000 = 0.85), and n is the sample size.

Plugging in the values, we get:

z = (0.85 - 0.9) / √(0.9 * 0.1 / 1000) = -1.5811

The P-value is the probability of getting a test statistic as extreme as -1.5811 or more extreme, assuming the null hypothesis is true. Since this is a two-tailed test (H1: p ≠ 0.9), we need to find the area in both tails of the standard normal distribution.

Using a standard normal distribution table, we find that the area to the left of -1.5811 is 0.0569, and the area to the right of 1.5811 is also 0.0569. Therefore, the total area in both tails is:

p-value = 0.0569 + 0.0569 = 0.1138

So,

     the p-value is 0.1138.
