Answer:

A circle is formed.

Step-by-step explanation:

When a plane, parallel to the base of a cone, slices a cone, a circle is formed

and for proof:

One of the interior angles of the triangle, angle y is equal to 67° and the exterior angle x is equal to 113°.

The interior angles of a triangle have a total sum of 180°.

Considering the triangle with interior angles: y, 51°, and 62° we have that;

y + 51° + 62° = 180°

y + 113° = 180°

y + 113° - 113° = 180° - 113° {subtract 113° from both sides}

y = 67°

the exterior angle x and the angle y lie on a straight line, so they sum up to 180°.

x + 67° = 180°

x + 67° - 67° = 180° - 67° {subtract 67° from both sides}

x = 113°

Therefore, the interior angle y = 67° and the exterior angle x = 113°.

Step-by-step explanation:

The equally likely events are

The probability that all three children are male

0.875.

the probability that at least one child is female.

0.875.

(a) The equally likely events for the gender of the three children, from oldest to youngest, are:

(b) The probability that all three children are male is (0.5)^3 = 0.125.

The probability that at least one child is female is the complement of the event "all three children are male," which means it is 1 - 0.125 = 0.875.

In conclusion, The probability that at least one child is female is 1 - (0.5)^3 = 0.875.

The smaller eigenvalue is -4 with multiplicity 2 and larger eigenvalue is 6 has multiplicity 1

If A is a square matrix of order n x n and v is a non-zero column vector of order n x 1 such that Av = λv , then the scalar (real number) λ is called an eigenvalue of the matrix A that corresponds to the eigenvector v.

According to the question,

We have a 3 x 3 matrix that has only two real distinct eigenvalues

Let two distinct eigen values be a and b

Its given that tr(A) = - 2

Det(A) = 96

If we add all the eigen values of a matrix it gives us trace of this and product of eigen values result to the determinant

Therefore , 2a + b = -2 --------(1)

a²b = 96 --------(2)

Using substitution method for solving these equations

=> b = -2 - 2a

Substituting the value of b in equation (2)

=> a²( -2 -2a) = 96

=> -2a² - 2a³ = 96

=> a²(1 + a) + 48 = 0

=> a³ + a² + 48 =0

Solving the cubic equation

a = -4 , 1.5-3i , 1.5+3i (but eigen values are only real)

therefore , a = -4

b = -2 -2(-4)

=> -2+8

=> 6

hence, the eigen values = -4 and 6

In linear equation ,The correct order from least time to greatest time is: Andy, Beth, Cindy.

Describe a linear equation using an example.

An equation with only one variable is referred to as a linear equation in one variable.

                   It has the mathematical formula Ax + B = 0, where A and B can be any two real numbers, and x is an unknowable variable with just one possible value. One such linear equation in one variable is 9x + 78 = 18.

Consider the provided information,

Andy walked [tex]2\frac{3}{4}[/tex]  mi at a constant speed of [tex]2\frac{1}{2}[/tex] mi/h.

As we know

       Time = distance/speed

           = [tex]\frac{2\frac{3}{4} }{2\frac{1}{2} }[/tex]

            =  [tex]\frac{11/4}{5/2}[/tex]

           = 11/40

Therefore, Andy takes 1.1 hours.

Beth walked 1 1/2 mi at a constant speed of 1 1/8 mi/h .

  time = [tex]\frac{1 1/2}{ 1 1/8}[/tex]

           = 3/2/ 9/8

           = 4/3

Therefore, Beth takes 1.33 hours.

Cindy walked for 1 h and 24 min at a constant speed of 1[tex]\frac{1}{4}[/tex] mi/h.

   1  hour 24 min   =  1 + 24/60   = 1.4 hours

    Therefore Cindy takes 1.4 hours.

Andy spent least time i.e 1.1 hours and Cindy spent greatest time i.e 1.4 hours.

The length of side DE of the rectangle ABCD is 11/5 units .

What is rectangle?

In euclidean plane geometry, a rectangle may be a quadrilateral with four right angles. It also can be outlined as: an angular quadrilateral, since angular means all of its angles square measure equal; or a tetragon containing a right angle.

Main body:

given:

AE = 4x+8       -----------(1)

CE = 7x - 3      -----------(2)

as we know diagonal of rectangle bisect each other , which means AE = CE

using the property , we get

4x+ 8 = 7x -3

taking like terms to one side,

7x - 4x = 8+3

3x = 11

x = 11/3

put the value of x in any equation,

AE = 4(11/3) +8

AE = 44/3 +24/3

AE = 68/3

Step-by-step explanation:

since AD is an altitude (height) of ABC, the angle at D must be 90° (that is the definition of an altitude or height).

so,

90 = x² + 6x + 18

72 = x² + 6x

0 = x² + 6x - 72

the general solution to such a quadratic equation

ax² + bx + c = 0

is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = (-6 ± sqrt(6² - 4×1×-72))/(2×1) =

= (-6 ± 18)/2 = -3 ± 9

x1 = -3 + 9 = 6

x2 = -3 - 9 = -12

A vector is a physical quantity that has both magnitude and direction

A vector equation is a linear combination of vector quantities

A curve is a path which an object follows.

Since we are given the vector equation r(t) = <t, -t, 2t>, to sketch the curve of the vector equation, we need to know the magnitude of the vector.

The magnitude of a vector r = <a, b, c> is |r| = √(a² + b² + c²)
