Anota una magnitud vectorial y explica tu respuesta
A physical quantity with both magnitude and direction is called a vector quantity.
A vector quantity is a physical quantity that has both magnitude and direction. One example of a vector quantity is velocity, which is defined as the rate of change of an object's position with respect to time. Velocity is a vector quantity because it has both a magnitude (speed) and a direction (the object's motion). For instance, if an object is moving with a speed of 20 meters per second to the north, its velocity would be 20 meters per second north. If the object's direction changes to east, its velocity would become 20 meters per second east. Therefore, velocity is a vector quantity because its value depends not only on the speed of the object but also on the direction in which it is moving.

My man, how did you even get these numbers??? no whole number multiplied by 6.65 even equals 22??? Regardless, here's what I did.
a) r = 40/2 = 20
A = πr^2 = (3.14)(20)^2 = 1256
b) 1256/50 = 25.12 basically, 26
c) 26 x 6.65 = 172.9
Thoughts and prayers my guy. Keep trying
Answer:
A. 1256[tex]ft^{2}[/tex] B. 26 pounds C. $172.90
Step-by-step explanation:
PART A
1st find the radius of the area
radius = diameter / 2
r = 40/2
radius = 20ft
Area of circle = radius^2* pi
Area = 400 * 3.14
Area = 1256 [tex]ft.^{2}[/tex]
PART B
1256 / 50 = 25.12
Because we can only buy full pounds and we need the whole area to be reseeded, we round 25.12 to 26.
26 pounds of seeds will be needed to reseed the whole area.
PART C
Multiply the number of pounds of seeds needed to be bought by 6.65
26 x 6.65

If the parent function is f(x) = x³, which transformed function is show in the graph?
The function g(x) = (x - 3)³ is shown in the graph. The solution has been obtained by using the concept of transformation.
What is transformation?
Any action that moves a polygon or other two-dimensional object on a plane or coordinate system is referred to as a transformation.
Translation, rotation, reflection, and dilation are all methods of transformation.
We are given a graph, from which we can say that when x = 3, then y = 0
The function must satisfy these values.
The functions g(x) = (x + 3)³ , g(x) = x³ + 3 and g(x) = x³ − 3 does not satisfy the point (3,0).
Also, the translation is 3 units to the right.
So the function shown in the graph is g(x) = (x - 3)³.

Please help:) calculus asking about delta functions
The value of delta such that the statement is true is:
δ = 0.0002
How to find delta?
We want to find δ such that:
if |x -3| < δ, then |5x - 15| < ε
So we have two absolute value inequalities to work with.
With ε = 0.001
If we take the second inequality and replace epsilong, we will get:
|5x - 15| < 0.001
We can take 5 as a common factor on the left side to get:
5*|x - 3| < 0.001
Dividing both sides by 5 gives:
|x - 3| < 0.001/5
|x - 3| < 0.0002

error variance was 20.31 with 36 df. A similar experiment under somewhat different
circumstances might have ȳ = 48.4 and s
2
= 45.06with 24 df.
Assuming the error variances are not homogeneous, test the null hypothesis that the
two population means are equal using a t-test at the 95% level of confidence.
Answer:
To perform a t-test for the equality of two population means with unequal variances, we can use the Welch's t-test. In this test, the formula for the t-statistic is:
t = (x1 - x2) / sqrt(s1^2/n1 + s2^2/n2)
Where x1 and x2 are the sample means, s1^2 and s2^2 are the sample error variances, and n1 and n2 are the degrees of freedom for the two samples.
Plugging in the given values, we have:
t = (52.8 - 48.4) / sqrt(20.31/36 + 45.06/24) = 4.25
Next, we need to find the critical t-value from the t-distribution table with degrees of freedom equal to the smaller of n1 and n2, which is 24. With a 95% confidence level, the critical t-value is approximately 2.492.
Since our calculated t-statistic (4.25) is greater than the critical t-value (2.492), we reject the null hypothesis that the two population means are equal. This suggests that there is strong evidence that the mean yield of oats is different between the two experiments.

In the triangle below, WXY is a equilateral triangle and XZ and WY
In the given equilateral triangle XYZ the relation which is true is WX = 2WZ. So option C is correct.
What are properties of equilateral triangle?An equilateral triangle is a particular kind of triangle in which the lengths of the three sides are equal. These are a few of its main characteristics:
Congruent angles exist for all three: An equilateral triangle has 60 degrees for each angle.
The three parties all agree: The perimeter of an equilateral triangle is three times the length of any one side because each side is the same length.
For any side, the same line serves as the altitude, median, and angle bisector:
A line segment perpendicular to the other side and drawn from one vertex is the altitude. A line segment called the median is drawn from one vertex to the middle of the other side. The line segment known as the angle bisector divides the angle made up of two sides.
Given that,
The triangle XYZ,
It is known that,
All the sides in the equilateral triangle are equal,
So it can be written as,
⇒ WX = WY = XY
⇒ WY = 2WZ = 2ZY

Refrigerator a uses 500 watts per hour when the motor is operating. The motor needs to run an average of 12 hours per day, every day, to stay at a constant, cold temperature. This model of refrigerator lasts an average of 20 years before it needs to be replaced and costs $1,000. Each kwh of electricity costs $0. 12.
To determine the total energy consumption of refrigerator A in a day, we need to first convert the power usage from watts to kilowatts.
500 watts/hour * 1 kilowatt/1000 watts = 0.5 kilowatts/hour
Next, we can calculate the energy consumption in kilowatt-hours (kWh) per day:
0.5 kilowatts/hour * 12 hours/day = 6 kilowatt-hours/day
To find the daily cost of running the refrigerator, we can multiply the energy consumption by the cost per kWh:
6 kWh/day * $0.12/kWh = $0.72/day
To calculate the yearly cost of running the refrigerator, we can multiply the daily cost by 365 days:
$0.72/day * 365 days = $262.80/year
To calculate the total cost of running the refrigerator for 20 years, we can multiply the yearly cost by 20:
$262.80/year * 20 years = $5,256.00
In addition to the cost of running the refrigerator, there is also the cost of purchasing the unit itself. In this case, the cost is $1,000.
Therefore, the total cost of owning and operating Refrigerator A for 20 years is:
$5,256.00 (operating cost) + $1,000.00 (purchase cost) = $6,256.00
It's worth noting that this calculation assumes that the cost of electricity remains constant over the 20-year lifespan of the refrigerator. In reality, the cost of electricity may increase over time, which would increase the overall cost of running the refrigerator.

If your car gets 33 miles per gallon, how much does it cost to drive 350 miles when gasoline costs $2.80 per gallon?
Answer:
$29.68 to drive 350 miles
Step-by-step explanation:
To find the cost of driving 350 miles, we first need to calculate the amount of gasoline required for driving 350 miles. We can use the formula:
gasoline = distance ÷ miles per gallon
Plugging in the given values:
gasoline = 350 ÷ 33
gasoline = 10.606060606060606
So, we need 10.61 gallons of gasoline to drive 350 miles.
Next, we multiply the amount of gasoline needed by the cost per gallon to find the total cost:
total cost = gasoline × cost per gallon
total cost = 10.61 × 2.80
total cost = 29.6780
Therefore, it would cost approximately $29.68 to drive 350 miles when gasoline costs $2.80 per gallon and your car gets 33 miles per gallon.
Answer: 350 mi * 1 gal / 33 miles * $2.80 / 1 gal = 29.69$
which means the cost is 2.8*(350/33)=29.69$
Step-by-step explanation:
Here, 2.80$/1 Gal.
Now we need to cancel out gallons, so we add a ratio with gallons.
2.80$/1 Gal. x 1 Gal/33 mi.
Now add the last data element to cancel out miles.
2.80$/1 Gal. x 1 Gal/33 mi. x 350 mi.
Cancelling out units and numbers gives,
(2.80$ x 350)/33. Continue reducing to an answer:
980$/33 = 29.69$

You (or your parents) purchase a new car for $19,725.00 plus 4.75% sales tax. The down payment is $2,175.00 and you (or your parents) have an average credit rating. How much interest is accrued after the first month?
Answer:
$90.12
Step-by-step explanation:
The principal amount of the loan is ...
(sale price)(1 + sales tax rate) - (down payment)
= $19,725×1.0475 -2175 = $18,486.94
For a secured loan, the APR charged for an average credit rating appears to be 5.85%, so the interest for the first month is
i = Prt = ($18,486.94)(0.0585)(1/12)
i = $90.12

The two pieces relate to the number of minutes used, since there's the 400-minute limit.
Piece #1: When you use less than or equal to 400 minutes:
Cost calculation: $47.35 + $13.94 = $61.29
Piece #2: When you use more than 400 minutes:
Cost calculation: $47.35 + $13.94 + $0.60(x-400)
The x-400 piece is because you're only charged the $0.60/minute beyond the 400 minutes, so 401 minutes needs just 1 minute of extra charge
Cost calculation cleaned up: 61.29 + 0.60x - 240 = 0.6x - 178.71

How many greetings will there be?
In total, the number of greetings will be 1159.
Why do you use the term "numbers"?Mathematical symbols used to represent quantities or values include numbers. They are employed in the measurement, comparison, addition, subtraction, multiplication, and division processes in mathematics. According to their qualities and properties, numbers can be categorized into a variety of groups, including natural numbers, whole numbers, integers, rational numbers, irrational numbers, real numbers, and complex numbers. There are specific properties and guidelines for mathematical operations for each group of numbers. Mathematics depends on numbers, which are also utilized in many other disciplines, including science, engineering, economics, and statistics.
The number of greetings exchanged between the host and the other mothers and daughters must be counted first. Since there is only one host, the number of mother-daughter pairs is 20 - 1 = 19. There are thus a total of 38 greetings, 19 between the host and the other moms, and 19 between the host and the other daughters.
The number of pleasantries exchanged between the guest mums and everyone else must next be tallied. The host, the other mothers, and the daughters must all be greeted, making a total of 20 - 1 = 19 guest mothers. Thus, each host mother must extend 1 + 19 + 20 = 40 greetings. There will be 760 greetings exchanged between the guest mothers and everyone, or 19 x 40.
The number of pleasantries exchanged between the mothers and the invited girls must also be tallied. Moreover, there are 20 guest girls, so 19 of them must welcome the mothers. As a result, there will be 361 pleasantries exchanged between the mothers and the guest daughters.
In total, the number of greetings will be 38 + 760 + 361 = 1159.

The requried two sides are equal, this triangle is an isosceles triangle, which means that two of the angles are equal to 45 degrees or less, and the triangle is acute.
What is the isosceles triangle?A triangle with two sides and two congruent angles is called an isosceles triangle.
To determine the value of x and the third side of the triangle, we need to first ensure that the triangle is a valid triangle, meaning that the sum of the lengths of the two shorter sides must be greater than the length of the longest side.
In this case, the two shorter sides are 2 and 3x, and the longest side is 9. We have,
2 + 3x > 9
Solving for x, we get:
3x > 7
x > 7/3
Since x must be a whole number, the smallest possible value for x that would make the triangle valid is 3. With x = 3, the third side of the triangle would be 3 × 3 = 9, which is equal to the longest side.
Therefore, the triangle has sides 2, 9, and 9.
Since two sides are equal, this triangle is an isosceles triangle, which means that two of the angles are equal to 45 degrees or less, and the triangle is acute.
