A parabola opening up or down has vertex
(-4, -6) and passes through (-14, 13/2)
Write its equation in vertex form.

It should be noted that the function that can model the data is a linear function since there's a constant difference or -5.The linear function is y = -5x - 9.

In this case, to determine whether the data is best modeled by a linear, quadratic, or exponential function, we can first plot the data points and see what type of curve they form. However, since we are only given five data points, it can be difficult to make a definitive determination.

One way to estimate the type of function is to look at the differences between the y values. For example, if the differences between the y values increase by a constant amount, then the data may be best modeled by a linear function. If the differences increase by a constant squared amount, then the data may be best modeled by a quadratic function.

Here, the constant difference will be:

= -29 - (-24)

= -5

This depicts a linear function.

Value of base and hypotenuse of triangle are 9√3 and 18 respectively.

A right triangle is a triangle with one interior angle measuring 90 degrees, known as a right angle. The side opposite to the right angle is called the hypotenuse, and the other two sides are known as the legs of the right triangle. The length of the hypotenuse can be found using the Pythagorean theorem,  that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs.

Height of triangle=9

Base of triangle=y

Hypotenuse of triangle=x

Using trigonometric ratio

Sin30°=Height/Hypotenuse

½=9/x

x=18

Cos30°=Base/hypotenuse

√3/2=y/18

y=9√3

Hence, value of base and hypotenuse of triangle are 9√3 and 18 respectively.

Answer:

y = [tex]\frac{1}{3}[/tex] x - 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x - 10 ← is in slope- intercept form

with slope m = - 3

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-3}[/tex] = [tex]\frac{1}{3}[/tex] , then

y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

to find c substitute (9, - 2 ) into the partial equation

- 2 = [tex]\frac{1}{3}[/tex] (9) + c = 3 + c ( subtract 3 from both sides )

- 5 = c

y = [tex]\frac{1}{3}[/tex] x - 5 ← equation of perpendicular line

The base 10 logarithmic function is a continuous function, which means that the distance between any two consecutive values on the number line is the same. Therefore, if 2 is halfway between 1 and 3, the value of the logarithm that is halfway between log 1 and log 3 should be the average of log 1 and log 3, which is:

(log 1 + log 3) / 2 = (0 + 0.477) / 2 = 0.2385

To find the value of x such that 10^x = 505, we can take the logarithm of both sides using base 10:

log 10^x = log 505

x = log 505

Using a calculator, we can find that log 505 is approximately 2.702.

To find the value of x such that 10^x = 100, we can take the logarithm of both sides using base 10:

log 10^x = log 100

x = log 100

Using a calculator, we can find that log 100 is exactly 2.

Therefore, the logarithm that is equal to 2 is log 100, not log 505.

We can use trigonometry to solve this problem. Let x be the distance from the foot of the ladder to the building, and let y be the length of the ladder. Then, we have:

tan(52) = y/x (since tangent = opposite/adjacent, and y is opposite to the angle of elevation and x is adjacent)

We also know that the ladder reaches 12 feet above the ground, so we have:

y = 12 + x (since y is the hypotenuse of the right triangle formed by the ladder, the ground, and the building)

We can substitute the second equation into the first to get:

tan(52) = (12 + x)/x

Simplifying this equation, we get:

tan(52)x = 12 + x

Using a calculator to find the tangent of 52, we get:

1.2799x = 12 + x

Solving for x, we get:

0.2799x = 12

x = 42.87 feet (rounded to two decimal places)

Therefore, the foot of the ladder is approximately 42.87 feet away from the building.

The approximate diameter of the pile of sand in the cone that sand was dumped in is 9.30 feet.

What is the approximate diameter?

A cone is a 3-dimensional object that consists of a ciruclar base and a vertex. The diameter is twice the length of the radius.

Radius = √[volume / (1/3 x π x height)]

=> Radius=√[136 / (1/3 x 22/7 x 6)]

If the number of school districts in Indiana were proportional to the number of school districts in Illinois, we would expect to see 440 school districts in Indiana.

Ratios are used to compare different parts of a whole, to compare different amounts of something, or to compare different measurements of the same thing.

The expected number of school districts in Indiana can be calculated by using the population of the two states.

We know that Illinois has 859 school districts and 12.9 million people, and Indiana has 295 school districts and 6.6 million people.

To determine how many school districts we would expect to see in Indiana if they were proportional to the number in Illinois, we can set up a proportion:

⇒number of school districts in Indiana/number of school districts in Illinois = population of Indiana/population of Illinois

⇒number of school districts in Illinois/number of school districts in Indiana = population of Illinois/population of Indiana

We can rearrange this proportion to solve for the number of school districts in Indiana:

⇒number of school districts in Indiana/number of school districts in Illinois = population of Indiana/population of Illinois

⇒number of school districts in Illinois/number of school districts in Indiana = population of Illinois/population of Indiana

Substituting the given values, we have:

number of school districts in Indiana =

6.6/12.9×859 ≈ 440

number of school districts in Indiana=

12.9 /6.6 ×859≈440

The cost a consumer pays to purchase a good or a commodity is known as the selling price. It is a price that is higher than the cost price and includes a profit margin. The cost of an item when acquired is referred to as its selling price (S.P.).

Here, we have

Given: A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation.

y = -3x² + 239x - 2268

At a maximum profit, dy/dx = 0, hence:

dy/dx = -6x + 239

0 = -6x + 239

x = 239/6

Triangles and circles have a close relationship in geometry, and several interesting properties and theorems connect them.

One triangle inscribed in circle: This statement is true, and it refers to the property of a circle that can be inscribed in a triangle. In other words, if we draw a circle that passes through all three vertices of a triangle, then the triangle is said to be inscribed in the circle. The center of the circle is called the circumcenter of the triangle, and it is the intersection point of the perpendicular bisectors of the sides.

Many triangles inscribed in circle: This statement is also true, as there are many different triangles that can be inscribed in the same circle. For example, if we draw a circle and pick any three points on its circumference, then we can connect these points to form a triangle that is inscribed in the circle.

One circle inscribed in triangle: This statement is true, and it refers to the property of a triangle that can be inscribed in a circle. In other words, if we draw a circle that is tangent to all three sides of a triangle, then the circle is said to be inscribed in the triangle. The center of the circle is called the incenter of the triangle, and it is the intersection point of the angle bisectors.

Many circles inscribed in triangle: This statement is false, as there can only be one circle that is inscribed in a given triangle. However, there are other circles that can be associated with a triangle, such as the circumcircle and the excircles. The circumcircle is the circle that passes through all three vertices of the triangle, while the excircles are the circles that are tangent to one side of the triangle and the extensions of the other two sides.

The distance between the two towns on the map was found to be 30.67 centimeters by setting up and solving a proportion between the distances on the map and the actual distances.

The problem provides us with a scale on the map of 3 cm to 45 km, which means that every 3 centimeters on the map represents 45 kilometers in the actual world. Let x be the distance between the two towns on the map in centimeters. Using the proportion, we can set up the relationship between the distances on the map and the actual distances as follows:

3 cm / 45 km = x cm / 460 km

Here, we set up a ratio between the distance on the map and the actual distance, where the distance on the map is x centimeters and the actual distance between the towns is 460 kilometers. We can then cross-multiply to solve for x:

45 km * x cm = 3 cm * 460 km

This gives us:

45x = 1380

x = 1380 / 45

x = 30.67 cm

Therefore, the distance between the two towns on the map is 30.67 centimeters.

Answer:

122 degrees.

Step-by-step explanation:

To calculate the measure of the sector that represents the probability of a rainy day using a spinner, we need to first determine the angle of the sector that represents the probability of a rainy day.

The probability of a rainy day is given as P(raining) = 0.34, which means that out of 100 days, 34 are rainy. Therefore, we can express the angle of the sector as:

Angle of sector = Probability of rain * Total angle of the spinner = 0.34 * 360 = 122.4 (rounded to the nearest degree)

So the measure of the sector that represents the probability of a rainy day is 122 degrees (rounded to the nearest degree).

Therefore, the answer is 122 degrees.

Answer:122°

Step-by-step explanation:

we have a 34% probability that it will rain and 66% that it won't rain. and full spin is 360 degrees which we can also symbolize as 100%.
