The missing side is 90 when all the other side are 30, 45 and 45.

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees. A closed, two-dimensional figure with four sides, four angles, and four vertices is called a quadrilateral. Square, rectangle, and trapezium are a few examples of quadrilaterals. A quadrilateral is a four-sided polygon with four edges and four corners that is used in geometry. The Latin words quadri, a variation of four, and latus, meaning "side," are the source of the name.

Given

Sides 30, 45 and 45

As we know sum of quadrilateral is 180

Let other side be x.

30 + 45 + 45 + x = 180

90 + x = 180

x = 180 - 90

x = 90

The missing side is 90 when all the other side are 30, 45 and 45.

Answer:

It is important to analyze the relationships between a sample and full population for several reasons:

To help make more informed statements about a population: Analyzing the relationships between a sample and full population helps us to make more accurate and informed statements about the population. By examining a sample, we can draw conclusions about the characteristics of the larger population.

To bring diverging data into analysis: Sometimes, a sample may not accurately reflect the larger population, particularly if the sample is small or biased. Analyzing the relationship between the sample and population can help to identify any diverging data and adjust the analysis accordingly.

To limit variance: Variance is a measure of how much the data varies from the mean. By analyzing the relationship between the sample and population, we can better understand the variance and take steps to limit it.

To find out how many data points are necessary to be statistically valid: Analyzing the relationship between the sample and population can help us to determine the sample size needed to be statistically valid. This can help us to avoid drawing inaccurate conclusions based on a sample that is too small.

Overall, analyzing the relationship between a sample and full population is important for ensuring that our analysis is accurate, representative, and informative.

It is important to analyze the relationships between a sample and the full population to limit variance and to help make more informed statements about a population.

Analyzing the relationships between a sample and the full population is important because it helps limit variance in the data and brings diverging data into the analysis. It also helps to determine how many data points are necessary to be statistically valid and make more informed statements about the population.

By examining a sample and comparing it to the full population, we can identify any biases or errors in our data and ensure that our conclusions are accurate and representative of the entire population. Additionally, understanding the relationship between the sample and the population can help us make predictions and draw conclusions with greater confidence and precision.
By understanding the relationship, you can ensure that the sample accurately represents the population, leading to better inferences and decision-making.

Answer:

1.) 12000

2.) 6750

3.) 2.41

Step-by-step explanation:

Given the Equation :

f(t)=12,000(3/4)^t. ; where, t = time ; f(t) = worth of car at time, t

When, car was purchased, t = 0

t = 0

f(0) = 12000(3/4)^0

= 12000 * 1

= 12000

2.)

f(2) ; this mean the worth of the car after 2 years :

f(2)=12,000(3/4)^t.

12000(3/4)^2

12000 * 0.5625

= 6750

When car will be worth 6000

f(t) = 6000

f(t)=12,000(3/4)^t.

6000 = 12,000(3/4)^t

6000 / 12000 = (3/4)^t

1/2 = (3/4)^t

Take the log of both sides :

Log(0.5) = log(0.75)^t

log(0.5) = tlog(0.75)

- 0.301029 = - 0.124938t

t = - 0.301029 / - 0.124938

t = 2.4094

t = 2.41 years

Answer:

2(x+3)(x-1)

Step-by-step explanation:

Because 2x^2+4x-6 can be divided by 2, you can divide them by two. This would make the equation 2(x^2+2x-3). To factor this, you have to find two equation that would make it true. The equation have to be _+_=2 and _x_=-3. The two blanks would be 3 and -1. 3+-1=2 and 3x-1=-3. This means that the equation is 2(x-1)(x+3).

Answer:

Step-by-step explanation:

The number of one-liter bottles she can fill from 5 gallons is A = 19

Given data ,

Aisha brings 5 gallons of a sports drink to a game

Now , 1 liter≈ 4.2 cups

And , 1 gallon is approximately equal to 3.78541 liters.

So, 5 gallons is approximately equal to 5 * 3.78541 = 18.92705 liters

On simplifying the equation , we get

Now, we divide the total liters by 1 liter (the capacity of each bottle) to find the number of bottles Aisha can fill:

Number of bottles = 18.92705 liters / 1 liter ≈ 18.93

Hence Aisha can fill approximately 19 one-liter bottles with 5 gallons of sports drink

Zach will need 19 feet of string to make his lanyard.

Zach and Jessica have 114 feet of string to make lanyards.

According to the given information, for every one foot Zach uses, Jessica needs 5 feet.

Let's assume that Zach uses x feet of string. Since Jessica needs 5 feet for every 1 foot Zach uses, she will need 5x feet of string.

The total length of string used by both Zach and Jessica should equal the total length of string they have, which is 114 feet.

So, we can set up an equation to represent this:
x + 5x = 114

Simplifying the equation:
6x = 114
Divide both sides by 6:
x = 19

Therefore, Zach will need 19 feet of string to make his lanyard.

Zach will need 19 feet of string to make his lanyard.

Answer:

Step-by-step explanation:

The distance between two points can be found using the formula

\(d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ \)

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A(5,-8) and B(2,9)

The distance between them is

\( |AB| = \sqrt{ ({5 - 2})^{2} + ({ - 8 - 9})^{2} } \\ = \sqrt{ {3}^{2} + ({ - 17})^{2} } \\ = \sqrt{9 + 289} \\ = \sqrt{298} \)

| AB | = 17.26267

We have the final answer as

Answer:

  a) missing y-values: 4, 8

  b) correct: y-intercept = 1

  c) y = 2^x

Step-by-step explanation:

You complete the table by reading point values from the graph. You have already correctly filled the y-values for x=0 and x=1. The y-value at x=2 is 4. The y-value at x=3 is off the chart, but we expect it to follow the same pattern: it will be 2×4 = 8.

The table values are (x, y) = (0, 1), (1, 2), (2, 4), (3, 8).

__

The y-intercept is the point where the graph crosses the y-axis: (0, 1). You have correctly identified 1 as the y-intercept.

__

The equation for the curve will be an exponential of the form ...

  y = a·b^x

The value of 'a' is the y-intercept: 1.

The value of 'b' is the ratio of successive y-values when x increases by 1.

  b = 2/1 . . . for x=1 and x=0

The equation will be ...

  y = 1·2^x

  y = 2^x . . . . . simplified

Answer:

Step-by-step explanation:

y = -4.9t² +42t +18.9

if the ball will be on the ground then y =0 and we need to find t by solving the quadratic equation

-4.9t² +42t +18.9 = 0

t= (-b±√b²-4ac)/2a, quadratic formula

t= {-42±√[42²-4*(-4.9)(18.9)] }/ 2(-4.9) , use calculator to solve

t= (-42 ±√2134.44)/ -9.8, solve the square root

t= (-42 ±46.2)/-9.8

one t = (-42 - 46.2)/-9.8 = - 88.2/ -9.8 = 9 seconds

another t = (-42 + 46.2)/-9.8 = 4.2 / -9.8 ≈ - 0.43 seconds reject this answer

The image of the coordinates after a dilation of (9, −7) by a scale factor of 4 centered at the origin include the following: (36, -28).

In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

Next, we would have to dilate the coordinates of the preimage (9, -7) by using a scale factor of 4 centered at the origin as follows:

Coordinate A (9, -7) → Coordinate A' (9 × 4, -7 × 4) = Coordinate A' (36, -28).

In conclusion, the coordinates of the image after a dilation are  (36, -28).
