What is the volume of a solid with dimensions 5 inches, 3 inches, and 4 inches? 15 cubic inches 30 cubic inches 45 cubic inches 60 cubic inches

Answer:

40

Step-by-step explanation:

This is an example of a composite function. And, in order to answer the given problem, we need to calculate first the inner function.

In this example, we have:

[tex]f(x) = x^{2} - 3x + 6\\g(x) = 5x - 10[/tex]

And, we are tasked to calculate the [tex]g(f(-4))[/tex]. Let's calculate first the [tex]f(-4)[/tex].

[tex]f(x) = x^{2} + 3x + 6\\f(-4) = (-4)^{2} + 3(-4) + 6\\f(-4) = 16 - 12 + 6\\f(-4) = 4 + 6\\f(-4) = 10[/tex]

Let's substitute this value to the function of g to get the final answer.

[tex]g(x) = 5x - 10\\g(f(-4)) = 5(10) - 10\\g(f(-4)) = 50 - 10\\g(f(-4)) = 40[/tex]

Thus, the final answer was 40.

The triangle ABC seems to be an scalene triangle since all of the sides AB, BC and CA have different lengths, and also the triangle is not a right angled triangle.

A scalene triangle is a type of triangle in which all three sides have different lengths. In other words, none of its sides are of equal length. As a result, all three angles in a scalene triangle are also different. It is different from an Isosceles triangle, where at least two sides are of equal length and an equilateral triangle where all sides are of equal length.

A right triangle is a type of triangle in which one angle is a right angle (90 degrees). This makes it different from other types of triangles such as acute triangle and obtuse triangle. The side opposite to the right angle is called the hypotenuse, and the other two sides are called legs. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse. This theorem is used to determine if a triangle is a right triangle or not.

The triangle ABC is a scalene triangle, as its sides have different lengths.

To determine whether it is a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (legs) is equal to the square of the length of the longest side (hypotenuse).

To find the side lengths, we can use the distance formula, which is

d = √((x2 - x1)² + (y2 - y1)²)

AB = √((9 - 6)² + (3 - 6)²) = √(3² + (-3)²) = √18 = 3√2

BC = √((9 - 2)² + (3 - 2)²) = √(7² + 1²) = √50 = 5√2

AC = √((2 - 6)² + (2 - 6)²) = √(4² + 4²) = √32 = 4√2

We know that in a right triangle, one of the side should be the hypotenuse and the other two should be the legs. We can check if any one of the side is satisfying that. But in this case, we can see that none of the sides are satisfying that condition, therefore the triangle ABC is not a right triangle.

Answer:

Step-by-step explanation:

A right angled isosceles triangle is a triangle with two sides of equal length and one right angle. To prove that the points (-3, 3), (3, -7) and (7,9) are the vertices of a right angled isosceles triangle, we can use the distance formula and the Pythagorean theorem.

The distance formula is used to calculate the distance between two points in a coordinate plane. It is given by:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Using the distance formula, we can find that the distance between the points (-3, 3) and (3, -7) is:

d = √((3 - (-3))^2 + ((-7) - 3)^2) = √(6^2 + (-10)^2) = √(36 + 100) = √136

Similarly, we can find that the distance between the points (-3, 3) and (7, 9) is also √136 and the distance between the points (3, -7) and (7, 9) is √36.

Now, we can use the Pythagorean theorem, which states that in a right angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

The Pythagorean theorem can be written as:

c^2 = a^2 + b^2

Since d1 and d2 are equal, we can say that the triangle is isosceles.

So, using the distance formula and the Pythagorean theorem, we have proven that the points (-3, 3), (3, -7) and (7,9) are the vertices of a right angled isosceles triangle.

Answer: To find the values of k for which the line y = x + k is tangent to the circle x^2 + y^2 = 25, we need to substitute y = x + k into the equation of the circle and solve for x.

x^2 + (x + k)^2 = 25

Expanding the square, we get:

x^2 + x^2 + 2xk + k^2 = 25

2x^2 + 2xk + k^2 = 0

Now we can solve for x by using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

Where a = 2, b = 2k and c = k^2

x = (-2k ± √(4k^2 - 42k^2)) / 2*2

x = (-k ± √(-3k^2)) / 4

Since the square root of a negative number is not a real number, we can see that there is no real value of x that will make the equation true. Therefore, the line y = x + k is never tangent to the circle x^2 + y^2 = 25

Answer:

Step-by-step explanation:

To find the values of k that will make the line y = x + k tangent to the circle x^2 + y^2 = 25, we need to set the equation of the line equal to the equation of the circle and solve for k.

First, we'll substitute y = x + k into the equation of the circle:

x^2 + (x + k)^2 = 25

Next, we'll expand the square on x + k:

x^2 + x^2 + 2xk + k^2 = 25

Now we'll combine like terms:

2x^2 + 2xk + k^2 = 25

We'll rearrange the equation so that x^2 is on one side

2x^2 + 2xk + k^2 - 25 = 0

Now we'll divide by 2

x^2 + xk + k^2/2 - 25/2 = 0

Now we'll complete the square

x^2 + xk + (k^2/2 - 25/2) = 0

x^2 + xk + (k^2/2 - 25/2) + (25/2) = (25/2)

(x + k/2)^2 = 25/2

Now we'll take the square root of both sides

x + k/2 = +-sqrt(25/2)

Now we'll solve for x

x = sqrt(25/2) - k/2 or x = -sqrt(25/2) - k/2

Now we'll substitute these values of x into the equation y = x + k and find the value of k.

x = sqrt(25/2) - k/2

y = x + k

y = sqrt(25/2) - k/2 + k

y = sqrt(25/2)

x = -sqrt(25/2) - k/2

y = x + k

y = -sqrt(25/2) - k/2 + k

y = -sqrt(25/2)

So the line y = x + k is tangent to the circle x^2 + y^2 = 25 when k = sqrt(25/2) or k = -sqrt(25/2)

The value of x in the interval 0 ≤x≤ pi is 2.083 so the graph f and g have parallel tangent lines

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation.  The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

f(x) = tan x

and, g(x) = x²

Now, f(x) = t g(x)

and, g(x) = x²

On differentiating f(x) we get

f'(x) = t g²(x) + 1

and, g(x) = 2x

Now, the parallel tangent line

f' (x) = g'(x)

t g²(x) + 1 = 2x

since the interval for x is 0 ≤x≤ pi.

So, the value of x = 2.083

Hence, the value of x is 2.083.
