Is a triangle 180 or 360?.

Answer:

To calculate the number of sides of the polygon, divide 360 by the amount of the exterior angle. For example, if the exterior angle is 60 degrees, then dividing 360 by 60 equals 6, which is the number of sides the polygon has.

The temperature when the plane reached an altitude of 5,000 ft will be 49.7°F.

According to the question,

For every thousand feet, the temperature drops 1.6°F.

So, 5000 feet (five thousand feet) the temperature drop

= (1.6 × 5)°F   ( using multiplication)        

=8°F

The temperature on the ground is 57. 7°F .

The temperature when the plane reached an altitude of 5,000 ft will be

                                = (57.7 - 8)°F        (using subtraction)

                                 =49.7°F

So, when the plane reaches an altitude of 5,000 ft, the temperature will be = 49.7°F.

In the given question of inequality, the greater than symbol makes the statement true, 14 > 5/6​.

A relationship between two expressions or values that is not equal to each other is known as inequality in mathematics. So inequality emerges from an imbalance.

"Less than or equal to," "less than," or "not equal to" are all ways to describe an inequality, which is a mathematical relationship between two expressions.

Both equations and inequalities are mathematical phrases created by connecting two expressions. The equal sign (=) in an equation denotes that the two expressions are regarded as equal. In contrast, an inequality indicates that the two phrases are not always equal by using the symbols >, <, or =.

Less than or equal to, larger than, less than, and more than or equal to are the four fundamental inequalities.

Therefore, the correct answer is option b) >.

A quadratic equation's graph is referred to as a parabola in mathematics. Y = a(x - p)(x - q), where p and q are the parabola's x-intercepts, or the x-values at which the parabola crosses the x-axis.

It is the factored form of a parabola, also known as the intercept form of a parabola. We can locate the function's x-intercepts or zeros with the use of factored form.

It is referred to as being in factored form when a quadratic expression is represented as the sum of two linear factors plus a constant. To establish if a graph reflects a function, use the vertical line test. The graph is a function if a vertical line drawn across it is moved and only ever touches it at one point.

The difference in the account balances at the end of the loan terms is $313.98.

The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also earns additional income in terms of the recipient, known as interest, taking into account the time value of money.

Given A homeowner is financing the cost of new windows.  Two lenders have approved the homeowner for a $12,000 loan.

principal  = $12,000

Offer 1:  4.5% annual simple interest, with a total account balance of $14,430 after a 54-month term

Amount of offer 1 = $14,430

Offer 2: 3.75% annual interest compounded monthly for a 66-month term

the amount is given by,

A = [tex]p(1 + \frac{r}{n} )^{nt}[/tex]

nt = 66 months

n = 12

r = 3.75% = 0.0375

p = $12,000

substitute the values in the formula,

A = 12000(1 + (0.0375/12))⁶⁶

A = 12000(1.228665)

A = $14,743.98

Difference in amounts = $14,743.98 - $14,430

By using the Pythagorean identities we can find the sine of an acute angle.

What is angle ?

An angle is a measure of rotation about a point or a line. It is a geometric concept that describes the amount of rotation between two lines or planes. Angles are typically measured in degrees or radians.

What is acute angle ?

An acute angle is an angle that measures less than 90 degrees. It is an angle that is smaller than a right angle. Acute angles are commonly found in triangles and other geometric shapes. They are represented by the symbol "α" (alpha) in trigonometry.

What is Pythagorean identities?

The Pythagorean identities are a set of trigonometric identities that are based on the Pythagorean theorem. They relate the sine, cosine, and tangent of an angle to the ratios of the sides of a right triangle. The Pythagorean identities can be used to find the sine of an acute angle by relating it to the ratio of the opposite side to the hypotenuse of a right triangle.

Specifically, the identity [tex]sin^2(x) + cos^2(x) = 1[/tex] can be used to find the sine of an acute angle x by first finding the cosine of x and then subtracting it from 1.

The equation becomes [tex]sin(x) = \sqrt{1 - cos^2(x)}[/tex].

Answer: The equation of a line can be written in the slope-intercept form y = mx + b, where m is the slope of the line and b is the y-intercept.

To find the equation of a line that passes through the point (3, 2) and cuts off equal intercepts on the x and y axes, we can use the following steps:

First, we need to find the slope of the line using the point (3, 2) and the fact that the line cuts off equal intercepts on the x and y axes. Since the line cuts off equal intercepts on the x and y axes, it means that it is a line of symmetry, which means that the slope of the line is zero.

Now we can use the point-slope form of a linear equation which is y-y1 = m(x-x1) and substitute the point (3,2) and the slope (0)

The equation of the line will be y = b where b is the y-intercept.

So the equation of the line which passes through the point (3, 2) and cuts off equal intercepts on the axes is y = 2

The line is a horizontal line passing through the point (3,2) and it cuts the x-axis at y = 2.

Step-by-step explanation:

The coordinates where the wood strips cross are (17.11,44). The solution is obtained using the concept of slope of line.

What is slope of line?

The change in y coordinate relative to the change in x coordinate is referred to as a line's slope in mathematics.

The symbols delta y and delta x stand for the net change in the y-coordinate and the net change in the x-coordinate, respectively.

We are given that Hana attaches thin strips of wood from each vertex perpendicular to the opposite edge.

Therefore, the point of concurrency will be in orthocenter.

We are given a triangle with coordinates X(0,0), Y(0,58), Z(36,44)

Now, we will find the slope

Slope(m) = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

Slope of XY = (58-0)/0-0 = 0

Slope of YZ = (44-58)/(36-0) = -7/18

We know that slope of line perpendicular to XY is 0

Using point slope form, equation of the altitude perpendicular to XY is

⇒[tex]y-y_{1} = m(x-x_{1} )[/tex]

⇒y-44 = 0(x-36)

⇒y=44

Slope of line perpendicular to YZ is 18/7

Using point slope form, equation of the altitude perpendicular to YZ is

⇒y-0 = 18(x-0)/7

⇒y = 18x/7

Substitute the value of y in the above equation, we get

⇒44 = 18x/7

⇒x = 17.11

Hence, the coordinates where the wood strips cross are (17.11,44).

The slope-intercept form is a way of expressing the equation of a straight line in algebraic terms. The equation of a line in slope-intercept form is typically written as:

y = mx + b

Where m represents the slope of the line and b represents the y-intercept, which is the point at which the line crosses the y-axis. The slope-intercept form is useful because it allows you to quickly identify the slope and y-intercept of a line, given its equation. The slope represents the rate of change of y with respect to x, and the y-intercept represents the initial value of y when x is equal to 0.
