Answer:

5. D

6. I think D. Because is y=mx+b and b is y the intercept in y. Y= 0-4 and replacing the -4 would remain at the end

Step-by-step explanation:

it just means to convert these equations into function definitions.

and a function looks like

y = ... something with x, factors, other functions, constants

1)

x + y = z

y = -x + z or z - x

2)

x - y = z

x - z = y or y = x - z

3)

x × y = z

y = z/x

4)

x/y = z

x = z × y

x/z = y or y = x/z

By using Euclid's first book, we can prove that the quadrilateral produced by perpendicular, unequal, bisecting diagonals is a kite. A kite is a quadrilateral with two pairs of adjacent sides that are equal in length. In this case, the two pairs of adjacent sides are formed by the diagonals bisecting the quadrilateral into four smaller triangles with equal areas.

According to Euclid's first book, when two lines intersect at a right angle (perpendicular), they form four right angles. In the case of a quadrilateral with perpendicular, unequal, bisecting diagonals, the diagonals intersect at a right angle and divide the quadrilateral into four smaller triangles with equal areas.

1. Draw a quadrilateral with perpendicular, unequal, bisecting diagonals.
2. Label the points where the diagonals intersect as A, B, C, and D.
3. Label the point where the diagonals intersect as E.
4. Use Euclid's first book to prove that the angles at E are all right angles.
5. Use Euclid's first book to prove that the four triangles formed by the diagonals are congruent (equal in area).
6. Use the definition of a kite to prove that the quadrilateral is a kite (two pairs of adjacent sides are equal in length).
7. Therefore, the quadrilateral produced by perpendicular, unequal, bisecting diagonals is a kite.

Answer:

135°

Step-by-step explanation:

First, count the amount of sides on the stop sign. There are 8 sides on the shape so we substitute this into a formula that we use to find the sum of the exterior angles in a shape.

(n - 2) × 180°

So the formula would look like (8 - 2) × 180°. The final answer after using this formula would be 1080°. This is the sum of the interior angles in this shape.

Then we do 1080° ÷ 8 (number of sides) = 135°.

Therefore, each angle is 135°, as the shape is a regular octagon.

(Extra information: Even if it is a irregular octagon the sum of all the interior angles will be 1080°. But each interior angle is not guaranteed to be 135°.)

Step-by-step explanation:

18/14 and 10/15 don't have the same value. Only equivalent fractions have same value.

These two are not equivalent fractions

Answer:

No.

Step-by-step explanation:

Without much calculation, we can notice that 18/14 is actually greater than 10/15 since its numerator is greater than its denominator, making it greater than 1. However, 10/15 is less than 18/14 since its numerator is less than its denominator making it less than 1. In short:

18/14 > 1

10/15 < 1

18/14 > 10/15

Step-by-step explanation:

To determine the function f(r) such that f(r)r is solenoidal, we need to first understand what it means for a vector field to be solenoidal.

A vector field is said to be solenoidal if its divergence is zero everywhere. Mathematically, if the vector field F is given by F = (F1, F2, F3), then it is solenoidal if ∇ • F = 0, where ∇ is the divergence operator.

Now, let's consider the vector field G = f(r)r, where r is the position vector in three-dimensional space, and f(r) is a scalar function. We can express G in terms of its components as follows:

G = (f(r)x, f(r)y, f(r)z)

where x, y, and z are the components of the position vector r. To determine f(r) such that G is solenoidal, we need to find the divergence of G using the expression for the divergence of a product of a scalar and a vector:

∇ • G = ∇ • (f(r)r) = (∇f(r)) • r + f(r)∇ • r

Now, since r = xi + yj + zk, we have:

∇ • r = ∂x/∂x + ∂y/∂y + ∂z/∂z = 3

Substituting this into the expression for ∇ • G, we get:

∇ • G = (∇f(r)) • r + 3f(r)

For G to be solenoidal, we need ∇ • G to be zero everywhere. This implies that (∇f(r)) • r + 3f(r) = 0. Since r is a vector, we can write this as:

∇f(r) + 3f(r)*(r/r²) = 0

where r/r² is the unit vector in the direction of r.

Multiplying both sides by r, we get:

r • ∇f(r) + 3f(r) = 0

This is a first-order partial differential equation known as the radial form of Laplace's equation. The general solution to this equation is:

f(r) = A/r³ + B

where A and B are constants.

Therefore, the function f(r) such that f(r)r is solenoidal is given by:

f(r) = A/r³ + B

where A and B are constants.

General conditions of congruency of triangles

Step-by-step explanation:

As no triangles are given, explaining the general rules to apply in congruency of all triangles.

Triangles are congruent on the basis of following conditions :

The equation of the line in point-slope form is y + 3 = (1/2)(x - 6), and in slope-intercept form is y = (1/2)x - 6.

To write the equation of a line in point-slope form and slope-intercept form given a point (6, -3) and a slope of 1/2:

1. Point-Slope Form:

The point-slope form of a linear equation is given by: \(y - y_1 = m(x - x_1)\), where (\(x_1, y_1\)) is a point on the line and m is the slope.

Substituting the values into the equation:

y - (-3) = 1/2(x - 6)

y + 3 = 1/2(x - 6)

2. Slope-Intercept Form:

The slope-intercept form of a linear equation is given by: y = mx + b, where m is the slope and b is the y-intercept.

Using the given slope (1/2) and the point (6, -3), we can solve for the y-intercept (b).

-3 = (1/2)(6) + b

-3 = 3 + b

b = -6

The equation in slope-intercept form is:

y = 1/2x - 6

The completed statement based on two-dimensional motion in the x-y plane can be presented as follows;

The two-dimensional motion in the x-y plane, the x part of the motion and the y part of the motion are independent, whether or not there is an acceleration in any direction. The correct option is therefore;

D) Whether or not there is an acceleration in any direction

Two-dimensional motion in the x-y plane can be analyzed by separating them into its horizontal (x) and vertical (y) components, and analyze each component using the one dimensional equations of motion.

The meaning of the motion on the x-y plane is that the x-direction motion of an object exclusive or excludes the effect of the motion of the object in the y-direction, vis a vis, the y-direction motion.

The horizontal and vertical components of the motion can be analyzes individually or by themselves, by making use of the equations of motion for a one-dimensional motion, whether or not there is an acceleration in any direction as the acceleration are also evaluated using one dimensional equations.

Answer: For a medium sundae, the problem tells us the scoops can be the same or different. If the two scoops are different flavors, there

are 5C2 = 5!/(2! × 3!) = (5 × 4)/(2 × 1) = 10 possibilities. If the two scoops are of the same flavor, there are 5 possibilities, one

for each of the five flavors. For the toppings there are three choices, therefore, for a medium sundae there are (10 + 5) × 3 =

15 × 3 = 45 combinations. Similarly, for three scoops of all different flavors, there are 5C3 = 5!/(3! × 2!) = (5 × 4)/(2 × 1) =

10 possibilities. For three scoops with two or three scoops of the same flavor, there 5 double scoops to choose from and 5 single

scoops to choose from giving 5 × 5 = 25 possibilities. To choose the two toppings, there are 3C2 = 3!/(2! × 1!) = 3 possibilities.

So, the total number of large sundae combinations is (10 + 25) × 3 = 35 × 3 = 105 combinations. In total, at Moo’s ice cream
