Answer:

two are supplementary. the measure of one of these angles is 12 degrees less than one-third the measure of the other.what is the measure of each angle

Let's call the measures of the two angles x and y, where x is the larger angle. We know that the two angles are supplementary, which means they add up to 180 degrees:

x + y = 180

We also know that one of the angles (let's say y) is 12 degrees less than one-third the measure of the other angle (x):

y = (1/3)x - 12

Now we can substitute the second equation into the first equation to solve for x:

x + (1/3)x - 12 = 180

Multiplying both sides by 3 to get rid of the fraction, we have:

3x + x - 36 = 540

Combining like terms, we get:

4x - 36 = 540

Adding 36 to both sides, we get:

4x = 576

Dividing both sides by 4, we get:

x = 144

Now we can use the first equation to solve for y:

144 + y = 180

Subtracting 144 from both sides, we get:

y = 36

Therefore, the measures of the two angles are 144 degrees and 36 degrees.

The sum of the sides of a regular polygon is 96ft, find the measure of it side.

Let's say that the regular polygon has n sides, and each side has length s. The formula for the sum of the sides of a regular polygon is:

sum of sides = n * s

We know that the sum of the sides is 96ft, so we can write:

96 = n * s

We want to find the length of each side, so we need to isolate s on one side of the equation. We can do this by dividing both sides by n:

s = 96/n

Now we can substitute this expression for s into the formula for the perimeter of a regular polygon:

Perimeter = n * s

Perimeter = n * (96/n)

Simplifying this expression, we get:

Perimeter = 96

We know that the perimeter of a regular polygon is the sum of the lengths of all its sides, so we can divide the perimeter by the number of sides to find the length of each side:

s = Perimeter / n = 96 / n

Therefore, the length of each side of the regular polygon is 96/n feet. We cannot determine the value of n from the given information in the problem.

Answer: 46.39 grams of radium

Step-by-step explanation:

We can use the half-life formula to solve this problem:

A = A₀(1/2)^(t/t₁/₂)

where:

A₀ = initial amount (present)

A = final amount (in 710 years)

t = time elapsed (710 years)

t₁/₂ = half-life (1690 years)

First, we need to calculate the number of half-lives that will occur in 710 years:

n = t / t₁/₂

n = 710 / 1690

n ≈ 0.42

This means that in 710 years, the amount of radium will be reduced to half its current amount (1/2). And then reduced to half again (1/2 * 1/2) in another 1690 years.

Now we can calculate the final amount of radium after 710 years:

A = A₀(1/2)^n

A = 70(1/2)^0.42

A ≈ 46.39 grams

Therefore, after 710 years, approximately 46.39 grams of radium will be left.

The equation y = (-2/3)x + 6 represents a line that is decreasing from left to right and intersects the y-axis at the point (0, 6).

The slope refers to the measure of the steepness of a line or a curve. It is defined as the ratio of the vertical change (rise) to the horizontal change (run) between any two points on the line or the curve.

The equation of a line can be written as with the help of slope intercept form is given by:

y = mx + b

Where "b" is the y-intercept and "m" is the line's slope of the line.

In the equation y = (-2/3)x + 6, we can see that the slope 'm' is -2/3, which means that for every unit increase in x, the y-value decreases by 2/3 of a unit. This tells us that the line represented by this equation is decreasing (i.e., sloping downwards) from left to right.

The y-intercept 'b' is 6, which means that the line intersects the y-axis at the point (0, 6). This is the starting point of the line, where the value of y is 6 when x is 0.

Therefore, the equation y = (-2/3)x + 6 represents a line that is decreasing from left to right and intersects the y-axis at the point (0, 6).

To find zx and zy, we need to take partial derivatives of z with respect to x and y. Taking z with respect to x, we get zx = 3x2 + 12xy and zy = 6x + 16y. Taking z with respect to y, we get zy = 6x + 16y and g(x, y) = 3xy - 7x. Therefore, gx = 3y - 7 and gy = 3x.

A derivative is a measure of how much a function changes as its input changes. More specifically, the derivative of a function at a particular point is the slope of the function at that point, which describes how quickly the function is changing at that point.

Geometrically, the derivative of a function at a given point can be thought of as the slope of the tangent line to the function at that point.

To find zx and zy, we need to take partial derivatives of z with respect to x and y, respectively.

Given z = [tex]x^3 + 6x^2y + 8y^2[/tex],

Taking partial derivative of z with respect to x, we get:

Let's denοte the width οf the rectangle as w. Then accοrding tο the prοblem, the length οf the rectangle is 7 inches mοre than the width, sο we can express the length as w + 7.

The area οf the rectangle is given by:

The perimeter οf the rectangle is given by:

[tex]P = 2 * (length + width) = 2 * (w + 7 + w) = 4w + 14[/tex]

According tο the problem, the area of the rectangle is equal to 2 inches mοre than 2 times the perimeter, so we can set up the following equation:

[tex]w^2 + 7w = 2(4w + 14) + 2[/tex]

These distances show that AB, which is only 10 nautical miles apart, and AB are the closest pair of islands.

Step-by-step explanation:

We must first locate the three pairs of islands in order to establish which pair is nearest before determining the safest route for the ship.

Give the three islands the letters A, B, and C. The three island groups are designated as AB, AC, and BC. Finding the closest pair is necessary.

We can leverage the separation between the islands to do this. Assuming that the islands are separated by the following distances:

A and B are separated by 10 nautical miles.

A and C are separated by 15 nautical miles.

B and C are separated by 12 nautical miles.

These distances show that AB, which is only 10 nautical miles apart, and AB are the closest pair of islands.

The trigonometry equations when evaluated are ∅ = 82π/125 and ∅ = 28π/23

Equation 1

Given that

cos ∅ = -8/17, π/2 < ∅ < π

Take the arc cos of both sides of the equation

So, we have the following

∅ = 82π/125

Equation 2

The trigonometry equation from the question is given as

tan ∅ = 2/5

The domain of the function is given as

π < ∅ < 3π/2

This means that the definition of the function is

tan ∅ = 2/5, π < ∅ < 3π/2

Take the arc tan of both sides of the equation

So, we have the following

∅ = tan⁻¹(2/5), π < ∅ < 3π/2

Express fraction as decimal

This gives

∅ = tan⁻¹(0.4), π < ∅ < 3π/2

Evaluate the arc tan

Answer: Let's call the base of the triangle "b" and the height of the triangle "h". We are given that the sum of the base and the height is 22 cm, so we can write:

b + h = 22

We want to find the dimensions for which the area of the triangle is a maximum. The formula for the area of a triangle is:

A = (1/2)bh

We can use the equation b + h = 22 to solve for h in terms of b:

h = 22 - b

We can substitute this expression for h into the formula for the area:

A = (1/2)b(22 - b)

Simplifying this expression, we get:

A = 11b - (1/2)b^2

To find the value of "b" that maximizes the area, we can take the derivative of this expression with respect to "b" and set it equal to zero:

dA/db = 11 - b = 0

Solving for "b", we get:

b = 11

Substituting this value of "b" back into the equation b + h = 22, we get:

h = 22 - b = 22 - 11 = 11

Therefore, the dimensions for which the area of the triangle is a maximum are:

base = 11 cm

height = 11 cm

And the maximum area is:

A = (1/2)bh = (1/2)(11 cm)(11 cm) = 60.5 square cm
