Find the area of a regular polygon with 6 sides. The radius is 6 ft. Please show work. Thank you :D

A linear model can be represented by the equation y = mx + b, where y is the dependent variable (megawatt hours generated by hydropower), x is the independent variable (years since 2007), m is the slope of the line, and b is the y-intercept.

To find the slope (m) and y-intercept (b) for this problem, we can use the two points given: (2007, 248) and (2012, 277).

m = (277 - 248) / (2012 - 2007) = 29 / 5 = 5.8

b = 248 - (5.8)(2007) = 248 - 11456 = -11208

So the linear model representing the number of megawatt hours generated by hydropower as a function of the number of years since 2007 is:

y = 5.8x - 11208

where x is the number of years since 2007.

The 4 types of triangle are

Acute triangle

Obtuse Triangle

Right triangle

Equivalent triangle

A triangle is said to be equilateral if each of its three sides is the same length. In the well-known Euclidean geometry, an equilateral triangle is also equiangular, meaning that each of its three internal angles is 60 degrees and congruent with the others.

A triangle having three acute angles is known as an acute triangle. A triangle having one obtuse angle and two acute angles is known as an obtuse triangle. No Euclidean triangle may contain more than one obtuse angle because in Euclidean geometry, a triangle's angles must add up to 180°.

A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.

Obtuse-angled triangles or obtuse triangles are triangles with any one of its angles being an obtuse angle or more than 90°. Only 180° is equivalent to the internal angles of an acute triangle.

Answer:175 are not suvs

Step-by-step explanation:

Answer: 175

Step-by-step explanation:

The length of BC is 5

The length of AC is 10

From the given information, we are to calculate the length of the given parts of line AC

From the given information,

B is the midpoint of AC

Thus,

We can write that

AB + BC = AC

and

AB = BC

Also, from the given information,

AB = 5

Therefore,

BC = 5

From the equation,

AB + BC = AC

Substitute the values of AB and BC

5 + 5 = AC

10 = AC

AC = 10

Hence, BC = 5 and AC = 10

The constant of proportionality of the graph is 12.

Proportional relationships are relationships between two variables where their ratios are equivalent. In other words, a proportional relationship is one in which two quantities vary directly with each other.

Proportional relationship can be represented mathematically as follows:

y = kx

Therefore, let's use (3, 36) to find the constant of proportionality.

Hence,

y = kx

36 = 3k

divide both sides by 3

3k / 3 = 36 / 3

The endpoint of a titration can be found by various methods like visual indicators, conductometric titration, volumetric titration, etc.

The endpoint of a titration is the point at which the reaction between the acid and base is complete. In other words, it is the point at which the acid and base have been neutralized, and the solution reaches a neutral pH of 7.0. There are several ways to determine the endpoint of a titration, including:

To find the endpoint, it is important to use a suitable indicator that changes color in the range of pH close to the endpoint of the titration. It's also important to use a burette to measure the volume of the titrant added and use it to plot the titration curve.

A linear equation is one that has the form y=mx+b in algebra. B is the slope, and m is the y-intercept. It's usual to refer to the previous clause as a "linear equation with two variables" because y and x are variables. The two-variable linear equations known as bivariate linear equations.

A scatterplot that shows the number of hours studied on the x-axis and the number of errors on the y-axis would best support the teacher's observation.

Error in math is an incorrect answer to a mathematical equation or problem. It can be caused by a variety of factors, such as inaccurate calculations, misreading instructions, or not understanding the problem. Error in math can be frustrating and can lead to poor grades, but it can also be an opportunity for learning and growth. With the proper guidance and understanding, students can learn from their mistakes and become better mathematicians.

The scatterplot would likely show a negative correlation, with the number of errors decreasing as the number of hours studied increases. This indicates that as students study more, their performance on multiplication tests improves. It could also show an outlier or two, which could indicate that some students are able to learn multiplication facts more quickly than others.

No, 3x2 is not an exponential function. An exponential function is a function in which the variable (x) is in the exponent.

The general form of an exponential function is f(x) = a^x, where a is the base and x is the exponent.

In the case of 3x2, the variable (x) is not in the exponent, it's being multiplied by the coefficient 3. This is a linear function, not an exponential function. The general form of a linear function is f(x) = mx+c, where m is the coefficient and c is the y-intercept.

In summary, 3x2 is not an exponential function. An exponential function is a function in which the variable (x) is in the exponent.

In mathematics, a percentage (from Latin: per centum, "by a hundred") is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%",although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number (pure number); it has no unit of measurement.

The term "percent" is derived from the Latin per centum, meaning "hundred" or "by the hundred". The sign for "percent" evolved by gradual contraction of the Italian term per cento, meaning "for a hundred". The "per" was often abbreviated as "p."—eventually disappeared entirely. The "cento" was contracted to two circles separated by a horizontal line, from which the modern "%" symbol is derived.

The longest side in a right triangle is the hypotenuse, which is the side opposite the right angle.

In ∆ XYZ, if X is the right angle, then the hypotenuse would be the side connecting points Y and Z. This is because in a right triangle, the hypotenuse is always the side opposite the right angle and is also the longest side in the triangle. This can be proven using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
