Similar triangles are triangles that share these two features presented as follows:

The bisection, represented by the altitude segment in this triangle, divides the triangle into two similar triangles, hence the equivalent side lengths are given as follows:

Then the proportional relationship for these side lengths is given as follows:

b/(28 - b) = 27/15

Step-by-step explanation:

We use the property that the sin of the angle of a right triangle is the ratio of the side opposite that angle divided by the hypotenus

Therefore
[tex]\begin{aligned}\sin x & = \dfrac{2.1}{4}\\& = 0.525\\\end{aligned}\\\begin{aligned}x &= sin^{-1}(0.525)\\& = 31.7^\circ \end{aligned}[/tex]

The shape with 7 sides is called a heptagon.

There a several shapes which has more number of sides than the usual shapes like square, circle or triangle.

As the number of the sides in the shape increases the propertied of the shape also changes. If the shape has 7 sides it is called a heptagon and if it has 6 sides than it is called a hexagon, it it has a 5 sides it is called a pentagon.

If all the 7 sides of the pentagon are equal in magnitude then the heptagon is said to be a regular heptagon but is not equal then they are called heptagon with different features.

Distance for the anchor drop every 5 seconds is,

⇒ E = 63 meters

Multiplication means to add number to itself a particular number of times. Multiply will be viewed as a process of repeated addition.

Given that;

A big ship drops its anchor.

Here, E represents the anchor's elevation relative to the water's surface (in meters) as a function of time t (in seconds).

E = - 2.4t + 75

Now, Distance for the anchor drop every 5 seconds is,

Put t = 5;

E = - 2.4t + 75

E = - 2.4 × 5 + 75

E = - 12 + 75

Answer: Jessica's average clothing budget for the first six months of 2001 was $102.

Explanation: To calculate the average amount of money that Jessica's budget allowed for clothing in the first six months of 2001, we first need to find her monthly budget.

We can do this by dividing her annual salary by 12 (the number of months in a year):

$48,960 / 12 = $4,080 per month

Next, we need to find her clothing budget for one month. We're told that her clothing budget is 5% of her monthly budget, so we can calculate this as follows:

5% of $4,080 = (5/100) x $4,080 = $204

Therefore, Jessica's clothing budget for one month is $204.To find her average clothing budget for the first six months of 2001, we simply need to multiply her monthly clothing budget by the number of months (i.e., 6):

$204 x 6 = $1,224

Finally, we divide this total by the number of months to find the average: $1,224 / 6 = $102

The measure of the angles required are,

Angle A = 58.3deg

Angle B = 121.7deg

If two angles sum up to 180 degrees, they are referred to as supplementary angles. When paired, supplementary angles result in a straight angle (180 degrees). In other words, if angle 1 plus angle 2 equals 180 degrees, angle 1 and angle 2 are supplementary. In this case, Angles 1 and 2 are referred to as "supplements" of one another.

Supplementary angles, by definition, add to to a sum of 180deg.

So what we know is:

Angle B + Angle A = 180deg

Angle B - 63.4deg = Angle A

By substitution:

Angle B + (Angle B - 63.4deg) = 180deg

Using the commutative property of addition, we can re-write the equation as:

(Angle B + Angle B) - 63.4deg = 180deg

We can add 63.4deg to both sides of the equation:

(Angle B + Angle B) - 63.4deg + 63.4deg = 180deg + 63.4deg

By simplifying, that gives us:

2(Angle B) = 243.4deg

Dividing both sides of the equation by 2, we can determine the measure of Angle B:

Angle B = 243.4deg/2 = 121.7deg

Now we have the measure of one of the angles, which we can plug back into our first equation:

Angle B + Angle A = 180deg

121.7deg + Angle A = 180deg

Subtracting 121.7deg from both sides, we get:

Angle A = 180deg - 121.7deg = 58.3deg

There’s your answer:

Angle A = 58.3deg

Angle B = 121.7deg

A- The average rate of change of g(x) over the interval [-2, 2] is 4, B- the instantaneous rates of change at the endpoints are different from the average rate of change over the interval.

A) To find the average rate of change of the function g(x) over the interval [-2, 2], we need to compute the difference quotient:

average rate of change = [g(2) - g(-2)] / [2 - (-2)]

First, we find the values of the function at the endpoints of the interval:

g(-2) = [tex]-2^{3}[/tex] - 6 = -14

g(2) = [tex]2^{3}[/tex] - 6 = 2

Substituting these values into the

average rate of change = (2 - (-14)) / (2 - (-2)) = 16 / 4 = 4

Therefore, the average rate of change of g(x) over the interval [-2, 2] is 4.

B) To compare this rate with the instantaneous rates of change at the endpoints of the interval, we need to find the derivatives of the function at x=-2 and x=2 using the power rule of differentiation:

g'(x) = 3[tex]x^{2}[/tex]

g'(-2) = 3[tex]-2^{2}[/tex] = 12

g'(2)  = 12

The instantaneous rate of change at x=-2 is 12, and the instantaneous rate of change at x=2 is also 12. These values are equal to the average rate of change over the interval [-2, 2], which is 4.

This means that the function g(x) is not a linear function over the interval [-2, 2], and the instantaneous rates of change at the endpoints are different from the average rate of change over the interval.

Moore's law is an observation made by Gordon Moore, co-founder of Intel Corporation, in 1965. It states that the number of transistors on a microchip doubles approximately every two years, while the cost of the chip is halved. Essentially, this means that computing power increases exponentially over time.

Moore's law is associated with exponential functions because it describes a situation in which a quantity (the number of transistors) grows at a rate proportional to its size, resulting in exponential growth. Exponential functions are often used to model phenomena in science, engineering, and other fields that exhibit this kind of behavior. In the case of Moore's law, the rate of growth is approximately 41% per year, or a doubling every 1.5 to 2 years. The formula for exponential growth is:

Where:

Moore's law can be expressed using this formula as:

Where:

For example, if a microchip had 1,000 transistors in 2000, according to Moore's law it would have 2,000 in 2002, 4,000 in 2004, 8,000 in 2006, and so on. The exponential function describes the growth of the number of transistors over time, and the formula allows us to predict future values based on past observations.

Answer:

The context that could not be modeled by an exponential function is "A car depreciates at a rate of 3.7% per year." Exponential functions are typically used to model situations involving growth or decay that occur at a constant rate over time. In this case, the rate of depreciation of the car is decreasing over time, so it cannot be modeled by an exponential function. A linear function or a more complex model may be more appropriate.

Silver Gym:

In Silver Gym, the membership is a flat fee (constant) of $45, and training sessions are $25 for each session (25x, x denoting the amount of sessions).

Therefore, total cost is:

Total Cost (c) = Training session x Training cost per session + Flat Fee

or

c = 25x + 45

Fit Factor:

In Fit Factor, the membership is a flat fee (constant) of $75, and training sessions are $15 for each session (15x, x denoting the amount of sessions).

Therefore, the total cost is:

Total Cost (c) = Training session x Training cost per session + Flat Fee

or

c = 15x + 75

You are trying to solve for the amount of training sessions that have to be bought in which both prices will be the same. Note that both equations are equal to c. Based on the transitive property of equality, if a = b and b = c, then a = c. Therefore:

c = 25x + 45

c = 15x + 75

15x + 75 = c = 25x + 45

15x + 75 = 25x + 45

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 25x and 75 from both sides of the equation:

15x (-25x) + 75 (-75) = 25x (-25x) + 45 (-75)

15x - 25x = 45 - 75

-10x = -30
