The largest
volcanic eruption in the last 10000 years was at Thera in 1520 BC. It brought about the
end of the Minoan civilisation in Greece.

The volume erupted by Thera equals that of a 400000 km column that reaches from the

Earth to the Moon. If this column has a square cross-section, find its width.

According to the information, it can be inferred that the balance after 3 months is that we have made interest payments for $107.6 of interest and $264.39.

To calculate the payment balance for the car loan we must take into account the following information:

According to the above, we must find how much the interest is equal to:

So, we must divide the result in the 12 months of the year

and later multiply it by the three months that are being asked.

Additionally, we must calculate how much the installment payment would be.

So we would pay 371.79 for the 3 months.

The radius of the circle with the same vertex is 6 and the height of the triangle is 10.39 and the area of the triangle is 62.34.

Since the arc divides the triangle into two regions of equal area, it follows that half of the circle's area is equal to the area of the triangle. The area of a triangle with sides 12 and 12√3 and a 60-degree angle can be found using the formula for the area of a triangle, which is 0.5bh.

The height of the triangle can be found using trigonometry, as the sine of 60 degrees is 0.8660. Thus, the height of the triangle is 10.39 and the area of the triangle is 62.34.

Since half of the circle's area is equal to the area of the triangle, the radius of the circle can be found by taking the square root of the area of the triangle and dividing it by pi. Thus, the radius of the circle is 6.

Answer:

central angle

Step-by-step explanation:

an angle with a vertex on the center of a circle and slides that are radii of that circle is called a central angle

Central angle has a vertex on the center of the circle and sides that are radii of that circle .

What does central angle mean?

A right angle, which has sides that are the radii of the circle, and a vertex that is at the center of the circle Given that it intercepts an arc with a length equal to the circle's radius, a central angle has radian measure [Math Processing Error].

Where can I find the center angle?

The angle that the arc at the center of a circle occupies is known as the central angle. The arms of the angle are created by the radius vectors. The formula for calculating a central angle is: Central Angle = Arc length(AB) / Radius(OA) = (s 360°) / 2r, where s denotes the length of the arc and r denotes the radius of the circle.

1 gallon equal to  3.785411784 liter.

The gallon is a unit of volume in imperial units and United States customary units. Three different versions are in current use:

The imperial gallon (imp gal), defined as 4.54609 litres, which is or was used in the United Kingdom, Ireland, Canada, Australia, New Zealand and some Caribbean countries.

The US gallon (US gal), defined as 3.785411784 L, (231 cubic inches) which is used in the US and some latin American and Caribbean countries.

The US dry gallon ("usdrygal"), defined as 1/8 US bushel (exactly 4.4.0388377086 L)

By using the above formula to convert US gallons to litres.

Solution: Inserting the value of a gallon in the above formula we will get:

Litre =1×3.785411784 =3.785411784

Answer:Given that Saul spoke with both boys and females, his generalization is accurate

Step-by-step explanation:?A generalization is a kind of abstraction where the general traits of specific cases are articulated as overarching concepts or claims. Generalizations presuppose a domain or collection of elements, as well as one or more shared characteristics.Why is being general useful?Generalization is the capacity to do an action, engage in an activity, or display a behavior in a variety of situations, with a variety of people, and at a variety of times. Our ability to complete routine tasks in a variety of contexts and settings is due to the fact that we have "generalized" the necessary skills.

18 pounds of candy costing $1.05 and 12 pounds of candy costing $1.35 are needed to be mixed to get a 30 pounds of mixture costing $1.17

An equation is an expression showing the relationship between two or more numbers and variables. An equation can either be linear, quadratic, cubic and so on depending on the degree.

Let x represent the amount of candy costing $1.05, y represent the candy costing $1.35.

The mixture is worth $1.17 a pound and is about 30 pounds. Hence:

1.05x + 1.35x = 1.17(30)    (1)

Also:

x + y = 30    (2)

The area of the region bounded by f(x)=(x-8)^2, g(x)=-x-2 and the x-axis is the definite integral of f(x)-g(x) from -2 to 8.

The area of the region bounded by f(x)=(x-8)^2, g(x)=-x-2 and the x-axis is given by the definite integral of f(x)-g(x) from -2 to 8. First, expand f(x) and g(x) to get f(x)=x^2-16x+64 and g(x)=-x-2. Then, subtract g(x) from f(x) to get f(x)-g(x)=x^2-16x+66. This is the equation of the area of the region. To calculate the area, use the definite integral of f(x)-g(x) from -2 to 8. This is equivalent to the integral from -2 to 8 of x^2-16x+66 dx. After integrating, the area is given by the expression (x^3/3)-8x^2+66x from -2 to 8, which is equal to 1176/3 units^2. Therefore, the area of the region bounded by f(x), g(x) and the x-axis is 1176/3 units^2.

The scale of figure A to Figure B is given by 9 : 5 and option C is the correct answer.

Shapes in various dimensions can be scaled using the Scale Factor. In geometry, we study many geometrical forms that exist in both two- and three-dimensions. The scale factor is a way to compare figures with similar appearances but differing scales or measurements. Consider two circles that resemble one another but may have different radii.

The scaling factor indicates how much a figure has increased or decreased from its initial value.

The scale of figure A to Figure B is given by:

Scale factor = Segment of figure A / segment of figure B

SF = 36 / 20

SF = 9 / 5

The distance from a to the line passing through b and c is 7/5.

To find the distance from a point to a line, you can use the cross product and the dot product.

First, find the vector pointing from a to b and the vector pointing from b to c:

u = b - a = (3, -5, 0) - (0, 3, -5) = (3, -8, 5)

v = c - b = (3, 0, -5) - (3, -5, 0) = (0, 5, -5)

Next, find the cross product of these two vectors, which gives a vector orthogonal to the plane defined by the line:

n = u x v = (-40, 0, 40)

Finally, find the dot product of n and a - b, which gives the magnitude of the projection of a - b onto n:

d = |n . (a - b)| / |n| = |(-40, 0, 40) . (-3, -8, -5)| / |(-40, 0, 40)| = 57 / √(40^2 + 40^2) = 57 / √1600 = 57 / 40 = 7/5

Therefore, the distance from a to the line passing through b and c is 7/5.

The cost of downloading 10 songs for Johnny is $30.

The cost of downloading music for Johnny can be represented by the expression 1.5x + 15, where x is the number of songs downloaded. To find the cost of downloading 10 songs, we can plug in x = 10 into the expression:

1.5 * 10 + 15 = 15 + 15 = 30

So, it will cost Johnny $30 to download 10 songs. This expression represents the total cost as the sum of a $30 $30 ($15 monthly fee) and a variable cost ($1.50 per song fee).

The fixed cost remains constant regardless of the number of songs downloaded, while the variable cost increases as more songs are downloaded.

For the given vectors the sum of u is  (-44/10,-6/10).

Vectors are mathematical objects that have both magnitude and direction.

The projection of u onto v is equal to the dot product of u and the unit vector of v divided by the magnitude of v.

The unit vector of v can be found by dividing v by its magnitude. Once we have the unit vector, we can multiply it by the dot product and add it to the initial point of v to find p.

Since u = (-4,-1) and v = (1,3), the magnitude of v is √(1^2 + 3^2) = √10 and the unit vector of v is (1/√10, 3/√10).

The dot product of u and the unit vector of v is

=> (-4)(1/√10) + (-1)(3/√10)

=> -4/√10 - 3/√10.

Thus,

=> p = (-4/√10 - 3/√10)(1/√10, 3/√10) + (1,3)

=> p = (-4/10 - 3/10, -1/10 + 3/10) + (1,3)

=> p =  (7/10 + 3/10, 2/10 + 3/10) = (10/10, 5/10).

To find n vector, we subtract p from u.

Finally,

=> n = u - p = (-4,-1) - (10/10, 5/10)

=> (-4 - 10/10, -1 - 5/10) = (-44/10,-6/10).

Answer:

4x + y = 15

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 )

here m = - 4 , then

y = - 4x + c ← is the partial equation

to find c substitute (2, 7 ) into the partial equation

7 = - 4(2) + c = - 8 + c ( add 8 to both sides )

15 = c

y = - 4x + 15

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

then

y = - 4x + 15 ( add 4x to both sides )

4x + y = 15 ← in standard form
