The Diagram Shows 3 Vertices Of A Parallelogram. Plot The 3 Possible Points For The 4th Vertex.

Answers

Answer 1

Answer:

(-1, -1), (-3,5), (5, -3)

Step-by-step explanation:

Answer 2

(-1, -1) is the 4th vertex.

Which is the required vertex ?

Let, 4th vertex is (x, y)

Given vertices of parallelogram are (-2. 2), (1, 1), (2, -2)

Here, (-2. 2) & (2, -2) are opposite vertices.

So, Midpoint of diagonals = \([(\frac{-2+2}{2}) ,(\frac{2-2}{2})]\) = (0, 0)

This is also midpoint of diagonal with vertices (1, 1) & (x, y)

So, (1+x)/2=0 ⇒ x = -1

& (1+y)/2=0 ⇒ y = -1

∴ 4th vertex is (-1, -1)

Surface area of triangular pyramid:

            In the triangular pyramid, base is an equilateral triangle, and the lateral faces are congruent triangles. So, to find the surface area add the area of base triangle with the area of 3 lateral triangles.

     a) Base area of pyramid:

            b= 8 cm

            h = 6.9 cm

         \(\boxed{\bf base \ area \ of \ pyramid = \dfrac{1}{2}*b*h}\)

                                                 \(= \dfrac{1}{2}*8*6.9\\\\=4*6.9\\\\= 27.6 \ ft^2\)

b) Area of one lateral surface area of pyramid:

                  b = 8 cm

     slant height = l = 9 cm

      \(\boxed{\text{\bf area of one lateral surface area of the pyramid = }\dfrac{1}{2}b*l}\)

                                                          \(\sf = \dfrac{1}{2}*8*9\\\\= 4 * 9\\\\= 36 \ ft^2\)

c) Lateral surface area of the pyramid = 3 * area of one lateral surface area of pyramid

                                                              = 3 * 36

                                                              = 108 ft²

d)TSA of pyramid:

      \(\boxed{\text{\bf Total surface area of pyramid = base area + lateral surface area}}\)

                                                         = 27.6 + 108

                                                        = 135.6 ft²

Q1) 80% of a dog's mass is equal to 24% of the mass of a lion. If the mass of the lion is 105 kg more than the mass of the dog, find the total mass of the dog and the lion.​

Answers

To solve this problem, let's denote the mass of the dog as D and the mass of the lion as L.

We are given that 80% of the dog's mass is equal to 24% of the lion's mass. Mathematically, this can be expressed as:

0.80D = 0.24L

We are also given that the mass of the lion is 105 kg more than the mass of the dog:

L = D + 105

We can use these two equations to find the values of D and L.

Substituting the value of L from the second equation into the first equation:

0.80D = 0.24(D + 105)

Now, let's solve for D:

0.80D = 0.24D + 0.24(105)

0.80D - 0.24D = 25.2

0.56D = 25.2

D = 25.2 / 0.56

D ≈ 45

Now that we have the value of D, we can find the value of L by substituting it back into the second equation:

L = 45 + 105

L = 150

Therefore, the total mass of the dog and the lion is:

D + L = 45 + 150 = 195 kg

So, the total mass of the dog and the lion is 195 kg.

(picture)

For an equation of the form ax^2 + bx+ c = 0, where the graph crosses the y-axis once and does not intersect

Answers

Answer:a

Step-by-step explanation:

The solution to the equation ax² + bx + c = 0 , has a graph that crosses the y-axis once and does not intersect the x-axis, then the equation has one real root and two complex conjugate roots that lie on either side of the axis of symmetry.

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

If the graph of the equation ax² + bx + c = 0 crosses the y-axis once, it means that the equation has one real root. This is because when x = 0, the equation becomes:

c = 0² + 0 + c = c

Therefore, the point (0, c) is on the y-axis, which means the graph crosses the y-axis once.

If the graph does not intersect the x-axis, it means that the discriminant b² - 4ac is negative. This is because the discriminant determines the nature of the roots of a quadratic equation, and when it is negative, the roots are complex (not real) and the graph does not intersect the x-axis.

So, the solution(s) of the equation ax² + bx + c = 0 are:

x = (-b ± √(b² - 4ac)) / 2a

Since the discriminant is negative, the term inside the square root is negative, and there are no real solutions for x. Instead, the solutions are complex conjugates of the form:

x = (-b ± i√(4ac - b²)) / 2a

where i is the imaginary unit. Since the real part of these solutions is -b/2a, which is the axis of symmetry of the parabola, and the parabola does not intersect the x-axis, the complex roots will be a conjugate pair that lie on either side of the axis of symmetry.

Hence , the quadratic equation is solved
