Based on the complementary relationship between sine and cosine, if sin 90º = 1, then cos 0º = 1 is the true statement. The cosine of 0º is equal to 1 because 0º is the complement of 90º.

Given that sin 90º = 1, we can determine the corresponding value of the cosine for certain angles based on the complementary relationship between sine and cosine.

In trigonometry, the cosine and sine are complementary functions. This means that the sine of an angle is equal to the cosine of its complement, and vice versa. The complement of an angle is the difference between that angle and a right angle (90º).

In this case, sin 90º = 1 implies that the angle 90º has a sine value of 1. Since the sine and cosine are complements, we can conclude that the cosine of the complement of 90º, which is 0º, must also be 1. Therefore, cos 0º = 1.

To summarize, based on the complementary relationship between sine and cosine, if sin 90º = 1, then cos 0º = 1 is the true statement. The cosine of 0º is equal to 1 because 0º is the complement of 90º.

Factors considered for potential aquifers: permeability, porosity, recharge. Avoid areas near contamination or high population density.

Examining the geology of a region for potential useable aquifers involves considering various characteristics and factors. Permeability, the ability of rocks or sediments to transmit water, is a key attribute. Highly permeable formations like sandstone or limestone facilitate water movement, making them favorable for aquifer development. Porosity, the amount of empty space within rocks or sediments, indicates the storage capacity of an aquifer. High porosity allows for greater water storage.

Recharge rates, the rate at which water replenishes the aquifer, are also important. Areas with consistent and sufficient rainfall or access to water sources like rivers and lakes tend to have higher recharge rates, making them suitable for aquifer utilization.

However, it is crucial to consider natural and human factors to determine areas to avoid. Proximity to contamination sources, such as industrial activities or landfills, can pose a risk to the water quality of an aquifer. Additionally, regions with high population density often face increased demands for water, which may lead to excessive groundwater extraction, causing depletion and long-term sustainability concerns.

Answer:

The slopes of the sides of the square ABCD are -1/3 and 3

Step-by-step explanation:

The coordinates of the vertices are;

A(-2, 5) and B(4, 3), therefore, we have;

The slope of segment AB, m, is given  as follows;

\(Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\)

Where, (x₁, y₁) = (-2, 5) and (x₂, y₂) = (4, 3), we have;

\(Slope, m \ of \ line \ AB, \ m_{AB}=\dfrac{3-5}{4-(-2)} = \dfrac{-2}{6} = -\dfrac{1}{3}\)

Therefore, given that the adjacent sides of a square are perpendicular, we have;

The slope of a line perpendicular to another line with slope, m is equal to the negative inverse of the slope of the line

Therefore, the given that the slope of a line = m, the slope of the perpendicular = -1/m

Therefore;

\(The \ slope \ of \ the \ perpendicular \ to \ the \ line \ AB = -\dfrac{1}{The \ slope \ of \ the \ line \ AB }\)

\(The \ slope \ of \ the \ perpendicular \ to \ the \ line \ AB = -\dfrac{1}{-\dfrac{1}{3} } = 3\)

Given that the one other side is parallel to the line AB, whereby the slope of parallel lines are equal, and that two sides are perpendicular to the line AB, we have, the slopes of the sides of the square ABCD are;

-1/3 and 3.

To evaluate \((g \circ f)(0)\), you'd start by rewriting this as \((g \circ f)(0) = g\big(f(0)\big)\) and your first step of evaluation is to evaluate \(f(0)\).

When you evaluate \(f(0)\), you have the following:

    \(f(0) = \dfrac{1}{0}\)

and this is undefined.  Since you cannot perform the first step of the evaluation, you cannot evaluate \((g\circ f)(0)\).

Answer:

m = 1/2

Step-by-step explanation:

Use two points on the line given.

(0 , 2) & (-4 , 0)

You are solving for the slope. The slope formula:

m (slope) = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (-4 , 0)

(x₂ , y₂) = (0 , 2)

Plug in the corresponding numbers to the corresponding variables:

m = (2 - 0)/(0 - (-4))

Simplify:

m = (2)/( 0 - (-4))

m = (2)/(0 + 4)

m = 2/4

Simplify the slope. Divide the common factor 2 from both the numerator and denominator:

m = (2/4)/(2/2) = 1/2

1/2 is your slope.

Answer:

The value of x° = 23°

Step-by-step explanation:

Given the angles of the right-angled triangle

We know that the sum of angles of a triangle is 360°.

so,

90° + 67° + x° = 180°

157° + x° = 180°

Subtracting 157° in both sides

157° + x° - 157° = 180° - 157°

x° = 23°

Therefore, the value of x° = 23°

The equation of the tangent line to the curve `y = 2ex cos(x)` at the point (0,2) is given by `y = 2ex + 2`.

To find an equation of the tangent line to the curve at the given point (0,2) whose equation is given by `y = 2ex cos(x)`, we need to determine the derivative `y'` of `y = 2ex cos(x)` first. Using the product rule, we have;

`y = 2ex cos(x)`...let `u = 2ex` and `v = cos(x)`, then `u' = 2ex` and `v' = -sin(x)`.`y' = u'v + uv'` `= 2ex cos(x) - 2ex sin(x)` `= 2ex(cos(x) - sin(x))`

Therefore, the derivative of `y = 2ex cos(x)` is `y' = 2ex(cos(x) - sin(x))`.

The equation of the tangent line to the curve at the point (0,2) is obtained by using the point-slope formula, which is given by: `y - y1 = m(x - x1)`where `(x1,y1)` is the point of tangency, `m` is the slope of the tangent line.

Substituting the values of `m`, `x1` and `y1`, we obtain: `m = y' |(0,2)` `= 2e(1 - 0)` `= 2e`Using the point-slope formula with `(x1,y1) = (0,2)` and `m = 2e`, we have: `y - 2 = 2e(x - 0)` `y - 2 = 2ex` `y = 2ex + 2`

The distance between the Earth and the Moon is equal to the distance between the Sun and the Moon multiplied by the sine of angle x.

Let,

EM = the distance between the Earth and the Moon.

y = the distance between the Sun and the Moon.

we know that,

In the right triangle of the figure

The sine of angle x is equal to divide the opposite side to angle x (distance between the Earth and the Moon.) by the hypotenuse (distance between the Sun and the Moon)

so, sin(x) = EM/y

Solve for EM

EM = (y)sin(x)

Therefore, the distance between the Earth and the Moon is equal to the distance between the Sun and the Moon multiplied by the sine of angle x.
