Remark

There are a couple of things you should keep in mind.

1. Your coefficient should always be a number between 1 and 9.999...

2. If you move right, you have a negative exponent. If you move left, you get a positive exponent.

Solution

So you are going right. The exponent is minus. You have 2 places to go to get a number between 1 and 9.99999. In this case, the coefficient is 3.55 So it goes in the blue box.

The red box is - 2

The answer is: blue 3.55

Answer:

\(\boxed {\boxed {\sf d= 13}}\)

Step-by-step explanation:

Distance can be calculated using this formula:

\(d= \sqrt {(x_2-x_1)+(y_2-y_1)\)

where (x₁, y₁) and (x₂, y₂) are the points. We are given the points (6, -9) and (1, 3). Therefore:

\(x_1= 6\\y_1= -9 \\x_2= 1\\y_2=3\)

Substitute the values into the formula.

\(d= \sqrt {(1-6)^2+(3--9)^2\)

Solve inside the parentheses.

\(d= \sqrt{(-5)^2 + (12)^2\)

Solve the exponents.

\(d= \sqrt { 25+144}\)

Add and take the square root.

\(d=\sqrt{169} \\d= 13\)

The distance is 13.

Using trigonometric ratio, the length of BE is 10 units, the value of sin B is 0.64 and cos B is 0.64 respectively

This is the ratio between the angles and sides of a right-angle triangle. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

In this problem, we have that

1)

Using tangent of B

tan B = opposite / adjacent

tan B = NE / BE

3/4 = 7.5 / BE

BE = 7.5 / 0.75

BE = 10

2)

To find sin B, we need to calculate the hypothenuse of the triangle which we will use Pythagoras's theorem

NB² = BE² + NE²

NB² = 10² + 7.5²

NB = 12.5

sin B = NE / NB

sin B = 7.5 / 12.5

B = sin⁻¹ (7.5 / 12.5)

B = 0.64

3)

cos B = BE / NB

cos B = 10 / 12.5

B = cos⁻¹ (10/12.5)

B = 0.64

Option (c) 26.7% of the global oceans are Marine Protected Areas (MPAs). Marine Protected Areas (MPAs) are designated areas in the oceans that are set aside for conservation and management purposes.

They are intended to protect and preserve marine ecosystems, biodiversity, and various species. MPAs can have different levels of restrictions and regulations, depending on their specific objectives and conservation goals.

As of the current knowledge cutoff in September 2021, approximately 26.7% of the global oceans are designated as Marine Protected Areas. This means that a significant portion of the world's oceans has some form of protection and management in place to safeguard marine life and habitats. The establishment and expansion of MPAs have been driven by international agreements and initiatives, as well as national efforts by individual countries to conserve marine resources and promote sustainable practices.

It is worth noting that the percentage of MPAs in the global oceans may change over time as new areas are designated or existing MPAs are expanded. Therefore, it is important to refer to the most up-to-date data and reports from reputable sources to get the most accurate and current information on the extent of Marine Protected Areas worldwide.

From the information given, the linear function is modeled by:

\(y = -10x + 60, 0 \leq x \leq 6\)

A linear function is modeled by:

\(y = mx + b\)

In which:

In this problem, it goes through point (0,60), hence when \(x = 0, y = 60\), meaning that the y-intercept is \(b = 60\).

It also goes through point (6,0), and considering the slope is given by the change in y divided by change in x:

\(m = \frac{0 - 60}{6 - 0} = -10\)

Hence, the equation is:

\(y = -10x + 60\)

After the car stops, the velocity will not be negative, hence the function is valid only for x = 0 to x = 6, that is:

\(y = -10x + 60, 0 \leq x \leq 6\)

Answer:

1/2 or 0.50

Step-by-step explanation:

To find the probability of getting either blue or green on a spinner, we must add both probabilities together.

\(\frac{3}{10}+\frac{1}{5} = ?\)

To make adding our two fractions easier, we need to make sure they have like denominators.

\(\frac{1*2}{5*2} =\frac{2}{10}\)

Now that the denominators of our probabilities are the same, we can add them together to get our answer.

\(\frac{3}{10} +\frac{2}{10}=\frac{5}{10}\)

\(\frac{5}{10} =\frac{1}{2}\) or \(0.50\)

To estimate the probability that the frog jumps off the board within 60 seconds, we need to simulate the frog's jumps using the provided random number table.

By tracking the jumps and determining if the frog reaches the edge within the given time frame, we can calculate the estimated probability.

We will simulate the frog's jumps using the random numbers provided in the table. Each random number will represent a jump duration in seconds. If the sum of the jump duration is equal to or exceeds 60 seconds, it means the frog jumps off the board within the time frame. We mark the jumps directly on or above the table to keep track of the simulation.

Repetition 1: Starting from the first random number 126, we mark the first jump. We continue adding the jump durations until the cumulative sum exceeds 60 seconds or we reach the end of the provided numbers. Let's say, after the fourth jump, the cumulative time is 68 seconds, which means the frog jumped off the board within 60 seconds.

Repetition 2: We repeat the process using the second set of random numbers starting from 127. We mark the jumps and calculate the cumulative time. Suppose after the fifth jump, the cumulative time is 56 seconds. In this case, the frog did not jump off the board within 60 seconds.

Repetition 3: We repeat the process using the third set of random numbers starting from 128. We mark the jumps and calculate the cumulative time. Suppose after the third jump, the cumulative time is 42 seconds. Again, the frog did not jump off the board within 60 seconds.

After performing the three repetitions, we count how many times the frog jumps off the board within 60 seconds. If the frog jumped off in one repetition out of three, then the estimated probability is 1/3 or approximately 0.333. This indicates that there is a 33.3% chance that the frog jumps off the board within 60 seconds based on the simulated data.

The extreme values of the function f(x, y) = xy(2y^2 x^4 − y^4) on the circle x^2 + y^2 = 1 are approximately ±0.235

To find the extreme values of the given function f(x, y) = xy(2y^2 x^4 − y^4) on the circle x^2 + y^2 = 1, we can use the method of Lagrange multipliers.

First, we write down the Lagrangian function L(x, y, λ) as follows:

L(x, y, λ) = xy(2y^2 x^4 − y^4) + λ(x^2 + y^2 − 1)

Then, we take the partial derivatives of L with respect to x, y, and λ and set them equal to zero:

∂L/∂x = y(2y^2 x^4 − y^4) + 2λx = 0

∂L/∂y = x(6y^3 x^4 − 4y^3) + 2λy = 0

∂L/∂λ = x^2 + y^2 − 1 = 0

Simplifying the first two equations, we get:

2y^5 x^4 − y^5 + 2λxy = 0

6y^4 x^4 − 4y^4 + 2λxy = 0

Dividing these equations, we obtain:

3x^4 = 2y^2

Substituting this back into the equation x^2 + y^2 = 1, we get:

3x^4 + x^2 = 1

This is a quartic equation in x^2. We can solve it using numerical methods to get the two possible values of x:

x ≈ ±0.681

y ≈ ±0.732

Plugging these values into the equation 3x^4 = 2y^2, we get:

y ≈ ±0.524

Now we can calculate the corresponding values of the function f(x, y) = xy(2y^2 x^4 − y^4):

f(x, y) ≈ ±0.235

Therefore, the extreme values of the function f(x, y) on the circle x^2 + y^2 = 1 are approximately ±0.235, and they are attained at the points (±0.681, ±0.732) and (±0.732, ±0.681).

Answer:

Must get common denominators (explained more in explanation)

Step-by-step explanation:

To add or subtract polynomials with unlike denominators, you first have to get common denominators, For example:

\(\frac{9}{q} +\frac{x-3}{q^{2} }\)

Multiply the first fraction on the left by \(q\) so we get:

\(\frac{9q}{q^{2} } +\frac{x-3}{q^{2} }\)

After this, you just have to add them

\(\frac{9q+x-3}{q^2}\)

Another example is:

\(\frac{x-3}{2} +\frac{x-4}{5}\)

We multiply the first fraction by 5 and the second fraction by 2 through distributive property

\(\frac{(5)x-3}{(5)2} +\frac{(2)x-4}{(2)5}\)

Multiply

\(\frac{5x-3}{10} +\frac{2x-4}{10}\)

Add

\(\frac{5x-3+2x-4}{10}\)

Simplify by combining like terms

Answer:

The volume of the box would be 6x³+33x²+54x+27.

Step-by-step explanation:

The new dimensions of the box would be (x+3), (2x+3), and (3x+3). Since the volume of a rectangular prism are calculated by multiplying the length, width, and depth, we can just multiply all three of these dimensions together to come up with the answer.

Using foil on the first two terms originally you get (x+3)×(2x+3)= 2x²+3x+6x+9 which can be simplified to 2x²+9x+9.

Then you multiply this equation by (3x+3). (2x²+9x+9)×(3x+3)= 6x³+6x²+27x²+27x+27x+27 which can be simplified to 6x³+33x²+54x+27.
