An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

A figure called an angle is one in which two rays originate from the same point. The two rays that make up the angle are referred to as its arms or sides, and this point is known as the angle's vertex. Reflex angles are those that are higher than 180 degrees but smaller than 360 degrees.

Types of Angles

Acute Angle – an angle that measure less than 90 degrees.

Right Angle – an angle which is exactly at 90 degrees.

Obtuse Angle – an angle whose value is greater than 90 degrees and less than 180 degrees.

Straight Angle – an angle which is exactly at 180 degrees.

The rocket is at its highest point 3.5 seconds after launch.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

To determine the time when the rocket is at its highest point, we need to find the value of t when h is a maximum. To do this, we can take the derivative of h with respect to t, and set it equal to 0.

h = -16t²+112t

∂h/∂t = -32t + 112 = 0

Solving for t we get,

t = 112/32 = 7/2 = 3.5 seconds

Thus, the rocket is at its most elevated point 3.5 seconds after launch.

By substituting the limits of integration and solving the definite integral, the volume of the solid is approximately 3.57 cubic units.

What is integration ?

Integration is a fundamental concept in calculus that deals with the problem of finding the total change in a quantity over a given interval. It is the reverse process of differentiation, which deals with finding the rate of change of a quantity.

We can think of slicing the solid into thin horizontal slices, each parallel to the y = 0 plane. The cross-section of each slice with the elliptic cylinder will be an ellipse. The area of each ellipse can be calculated using the formula for the area of an ellipse, which is πab, where a and b are the semi-major and semi-minor axes of the ellipse.

The semi-major axis of the ellipse is 2, and the semi-minor axis is √(4 - 4x^2) = √(4(1 - x^2)) = 2√(1 - x^2). So the area of each slice is A(x) = π(2)(2√(1 - x^2)) = 4π√(1 - x^2)

The height of each slice is dy = dz = dx, since the slices are parallel to the y = 0 plane and the height of each slice is equal to the change in y or z between two consecutive slices.

So, the volume of the solid is ,

∫ (4π√(1-x^2)) dx from x = -1/2 to x = 1/2

By substituting the limits of integration and solving the definite integral, the volume of the solid is approximately 3.57 cubic units.

The statement when the blanks are completed is

From the question, we have the following parameters that can be used in our computation:

∆ABC has A(-2, 5), B(-4, -2), and C(3, -4) as its vertices

The lengths are then calculated as

length = √[(x₂ - x₁)² + (y₂ - y₁)²]

So, we have the following representations

AB = √[(-4 + 2)² + (-2 - 5)²] = √53

AC = √[(3 + 2)² + (-4 - 5)²] = √106

BC = √[(3 + 4)² + (-4 + 2)²] = √53

This means that the triangle is a right triangle

The length of the second side is 10/3 inches or 3.33 inches. The triangle is a scalene triangle.

What is a variable?

A variable is a characteristic that can be measured and has multiple values. Variables include height, age, income, province or country of birth, school grades, and type of housing. Variables are divided into two types: categorical and numerical.

Given that the measure of the first side is 5 inches less than the second side. The third side is 3 inches more than the first side.

Assume that the length of the second side is x.

The length of the first side is x-5 inches

The length of the third side is (x-5) + 3 inches

= x - 5 + 3

= x - 2 inches.

The perimeter of a triangle is the sum of all sides of a triangle.

The perimeter of the triangle is x +( x-5) +  x - 2

According to the question,

x +( x-5) +  x - 2 = 17

Combine like terms:

(x+x+x) + (-5-2) = 17

3x - 7 =17

The equation of line that passes through (4,2)

3x-4y-4 = 0

A line is a geometry object characterized under zero width object that extends on both sides. An straight line is just a line with no curves. So, a line that extends to both sides to infinity and has no curves is called an straight line.

Given,

Line l₁ passes through point (4,2)

Equation of the line l₁ passing through a point (x', y') ≡ (4, 2), if its slope is m₁:

y-y' = m₁(x-x')

y-2 = m₁(x-4)     --------- (a)

Line l₂ passes through the points (x₁, y₁) ≡(-2,2) and (x₂, y₂) ≡ (2,5)

Slope of line l₂ (m₂) = (y₂-y₁)/(x₂-x₁)

⇒m₂ = (5-2)/(2-(-2))

⇒m₂ = 3/4

since l₁ and l₂ are parallel

then slope of l₁ will be equal to l₂

⇒ m₁ = m₂

⇒ m₁ = 3/4

Putting value of m₁ in equation (a)

y-2 = 3/4(x-4)

⇒ 4y-8 = 3x-12

⇒ 4y+4 = 3x

⇒ 3x-4y-4 = 0

The three points that are in the solution set are E(3,0) F(5,-4)

Plotting graphs?

When plotting graphs, you typically use a set of Cartesian coordinates to specify the location of each point on the graph. The Cartesian coordinates, also known as rectangular coordinates, consist of an x-coordinate and a y-coordinate. The x-coordinate specifies the position of the point along the horizontal axis, also known as the x-axis, and the y-coordinate specifies the position of the point along the vertical axis, also known as the y-axis.

To determine which of the six points are a solution to the equation

2x + y = 6, we can substitute the x and y values of each point into the equation and see if it holds true.

The points are A (1, -6), B (7, -3), C (-1, 8), D (3, -5), E (3, 0), F (5, -4)

A = (1, -6), 2x+y = 21 + -6 = 6 , it is not a solution

B = (7,-3) , 2x+y = 27 + -3 = 6 , it's not a solution

C = (-1,8) , 2x+y = 2*-1 + 8 = 6 , it's not a solution

D = (3,-5) , 2x+y = 23 + -5 = 6 , it is not a solution

E = (3,0) , 2x+y = 23 + 0 = 6, it's a solution

F = (5,-4) , 2x+y = 2*5 + -4 = 6, it's a solution

So, the three points that are in the solution set are E(3,0) F(5,-4)

We can plot the points on a coordinate plane, with x on the horizontal axis and y on the vertical axis.

And connect all three points, which would result in a line.

You can label this line as 2x+y=6, and any point that lies on that line is a solution for the given equation.

Here is a set of directions on how to walk from the schoolhouse to the grocery store: walk 5 units west and 12 units north.

To travel from the schoolhouse to the grocery store, find the distance between each point horizontally and vertically.

To find the horizontal distance between the schoolhouse and the grocery store on a coordinate plane, find the difference between the x-values of the two points.

x-distance = |4 - (-1)| = 5

Since the direction is from right to left, it should be 5 units west.

To find the vertical distance between the schoolhouse and the grocery store on a coordinate plane, find the difference between the y-values of the two points.

y-distance = |-5 - (7)| = |-12| = 12

Since the direction is upwards, it should be 12 units north.
