Answer:
.
Step-by-step explanation:
The distance between two points (x1, y1) and (x2, y2) is given by the formula:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Here, (x1, y1) = (-7, 3) and (x2, y2) = (5, 3).
Substituting these values, we get:
d = sqrt((5 - (-7))^2 + (3 - 3)^2)
= sqrt((12)^2 + (0)^2)
= sqrt(144)
= 12
Therefore, the distance between (-7, 3) and (5, 3) is 12 units.
Marissa and Lauren are traveling to Niagara Falls in Canada. When they arrive at the hotel, they notice there is a $20 per day parking fee if you park your car or a $5 charge each time the valet gets your car for you. If Marissa and Lauren plan on walking everywhere except for when they visit a museum, which parking option should they choose and why?
Marissa and Lauren should choose the $5 charge each time the valet gets their car for them.
What is car?A car, also known as an automobile, is a wheeled motor vehicle used for transportation. Most definitions of cars say that they run primarily on roads, seat one to eight people, have four tires, and mainly transport people rather than goods. Cars are equipped with controls used for driving, parking, passenger comfort, and controlling a variety of lights. Over the decades, additional features and controls have been added to vehicles, making them progressively more complex.
Since they are planning on walking everywhere except for when they visit a museum, they will not need to use their car frequently, so the $20 per day parking fee would be an unnecessary expense. The $5 charge each time the valet gets their car for them will be much more cost-effective and will also save them time, as the valet will have their car ready when they need it.

Members of a charity organization are interested in finding ways to make it easier for individuals to donate money to their cause.
They analyze the data from their last fiscal year of donations and find that 75% of their money came from online sources. Of the 60% of donations that came from regular donors (repeat donors), approximately 95% were submitted through the organization’s website.
Is the method of donation (online vs. not online) independent from the type of donor (regular vs. new) in this sample?
We cannot determine whether the method of donation is independent from the type of donor in this sample based on the information given in the question.
Define the term statistical analysis?Statistical analysis is the process of collecting, cleaning, analyzing, and interpreting data using statistical methods and techniques.

Hence, in answering the stated questiοn, we may say that As a result, we equatiοn must add (2x - 1)2 + 5 tο 6x² + 9x - 8 tο get 4x² - 8x + 6.
What is equatiοn?A algebraic equatiοn is a strategy fοr linking twο prοpοsitiοns and expressing equivalence using the equals symbοl (=).

We can cοnclude frοm cοmparing the twο fοrmulas that a = 4, b = -8, and c = 6.
Sο we must "finish the square" by adding and remοving a term equal tο (b/2a)2. In this instance, we have:

The angle of elevation represented by θ is equal to 1.13186 in radian approximately to 5 decimal place.
How to calculate for the angle of elevation θ in degreeThe angle of elevation is the angle θ between the horizontal line given as 2000 feet and the line of sight which is above the horizontal line.
The angle θ in degree is calculated, and then converted to radian as follows:
since the camera and the rocket is 4255 feet apart, then;
θ = tan⁻¹(4255/2000)
θ = 64.82482°
To convert 64.82482° to radian, we multiply by π/180
θ' = 64.82482° × π/180
θ' = 1.13186 approximately to 5 decimal place.

The probability of obtaining at least 1 six in 5 throws of the die is 1 - (1-p)⁵.
What is the probability?
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen.
The probability of obtaining a six on one throw of the die is given as a fraction, say p.
We are not given the value of p, but we know that the die is biased so that the probability of obtaining a six is greater than 1/6.
The probability of not obtaining a six on one throw of the die is (1-p), since the sum of the probabilities of all possible outcomes must be 1.
To find the probability of obtaining at least 1 six in 5 throws of the die, we can use the complement rule.
This states that the probability of an event happening is equal to 1 minus the probability of the event not happening.
So, the probability of not obtaining any sixes in 5 throws of the die is:
(1-p)⁵
The probability of obtaining at least 1 six in 5 throws of the die is therefore:
1 - (1-p)⁵
This formula gives the probability of obtaining at least one six in any 5 throws of the die, regardless of the order in which the throws occur.
Note that we cannot determine the exact value of the probability without knowing the value of p, but we can use the given information that the die is biased so that the probability of obtaining a six is greater than 1/6 to conclude that the probability of obtaining at least one six in 5 throws of the die is also greater than 1/6.
Therefore, The probability of obtaining at least 1 six in 5 throws of the die is 1 - (1-p)⁵.

Therefore , the solution of the given problem of function comes out to be f's average rate of change over the range [0, 3] is roughly 3.862.
What is function?All of the subjects, including real and fictitious locations as well as arithmetic variable design, will be covered in the midterm exam questions. a schematic illustrating the connections between various components that work together to produce the same outcome. A service is made up of many unique parts that work together to produce unique outcomes for each input.
Here,
f(b) – f(a) = average rate of change (b - a)
Since a = 0 and b = 3 in this instance, we get:
typical rate of change is equal to f(3) - f(0) /. (3 - 0)
We must assess the integral with x = 3 substituted before we can determine f(3):
From x=0 to x=3, compute f(3) = t3 + 2 dx.
By substituting u = t³ + 2, du = 3t² dt, we can assess this integral:
=> f(3) = ∫√(t³ + 2) dt evaluated from t=0 to t=3
=> (1/3) * ∫√u du evaluated from u=2 to u=29
=> (1/3) * [(2/3) * (29^(3/2) - 2^(3/2))]
=> 11.585
Simply enter x = 0 into the integral and assess it to obtain f(0):
Evaluation of f(0) = t³ + 2 dx from x=0 to x=3 = 0
Therefore, the average rate of change of f over the range [0, 3]
Average rate of change is
=> (11.585 - 0) / 3 - (f(3) - f(0))
=> 3.862
Therefore, f's average rate of change over the range [0, 3] is roughly 3.862.

Zanas house is at A, 500 feet from the intersection, and Tan's house is at B, 750 feet from F. Which distance is longer, the distance from Zana's house to Tan's house or the distance from Theresa's house to Is house? Show how you know.
Step-by-step explanation:
what is meant by "distance" ?
ground distance (using the roads to get there), or air distance (line of sight) ?
I have to assume we mean air distance, as the ground distance is the same in both cases (500 ft + 750 ft = 1250 ft).
for the air distance we need to use Pythagoras
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90° angle), and a and b being the legs.
Zana to Tan = AB
FB² = FA² + AB²
750² = 500² + AB²
562,500 = 250,000 + AB²
312,500 = AB²
AB = 559.0169944... ft
Theresa to Ivy = CE
CE² = CF² + FE²
CE² = 500² + 750² = 250,000 + 562,500 =
= 812,500
CE = 901.3878189...
so, the distance from Theresa to Ivy is longer.

The other leg measures 4 centimetres in length.
The right triangle in the illustration has a hypotenuse that is 5 cm long and a leg that is 3 cm long. The length of the other leg must be determined.
Applying the Pythagorean theorem, which asserts that the square of the hypotenuse's length is equal to the sum of the squares of the two legs of a right triangle, we may write:
[tex]a^2 + 3^2 = 5^2[/tex]
When we simplify this equation, we obtain:
[tex]a^2[/tex] + 9 = 25
By taking 9 away from both sides, we arrive at:
[tex]a^2[/tex] = 16
By multiplying both sides by their square roots and keeping in mind that a must be positive, we arrive at:
a = 4
Hence, the other leg is 4 cm long.
