The corresponding measurements for angles A and B are 123° and 57°

Supplementary angles are angles that sum up to 180 degrees e.g angle 140° and angle 40° are supplementary angles because the sum of 140° and 40° is equal to 180°

Given that: angle A= (5x-22) and m∠B= (x+28),  and ∠A and angle ∠B are supplementary angles. Thus:

A + B = 180°

(5x-22) + (x+28) = 180°

5x-22 + x+28 = 180°

6x + 6 = 180

6x = 180 -6

6x = 174

x = 174/6 = 29°

∠A = (5x-22)           put x = 29°

∠A = 5(29) -22  

    = 145-22

Option (a) is correct, i.e., the equation of the line in point-slope form with given slope -2/3 passing through the given point (2,-3) is y+3 = -2/3 (x-2).

Point slope form is used to represent a straight line using its slope and a point on the line.

The equation of a line in point-slope form whose slope is 'm' and which passes through a point (x₁ ,y₁) is

y - y₁ = m (x-x₁).

Here we have slope m= -2/3 and the point (x₁ ,y₁) = (2,-3).

Therefore, the point-slope form of the equation is

             y- (-3) = - 2/3 (x-2)

        ⇒ y + 3= -2/3 (x-2).

       ⇒ Option(a) is correct.

Therefore, equation of the line in point- form slope is y+3 = -2/3 (x-2).

The equation of parabola is ( x + 5 )² = 16 ( y - 6 )

What is a Parabola?

A Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line

The equation of the parabola is given by

( x - h )² = 4p ( y - k )

where ( h , k ) is the vertex and ( h , k + p ) is the focus

y is the directrix and y = k - p

Given data ,

The vertex of the parabola is ( -5 , 6 )

The directrix of the parabola y = 2

From the equations of parabola , we know that

The vertex ( h , k ) = ( -5 , 6 )

h = -5

k = 6

y = k - p

y = 2

k - p = 2

Substituting the value k in the equation , we get

6 - p = 2

On Simplifying , we get

p = 4

So , now we have the values of h , k , and p

The equation of the parabola is

( x - h )² = 4p ( y - k )

Substituting the values , we get

( x - (-5) )² = 4 x 4 ( y - 6 )

( x + 5 )² = 16 ( y - 6 )

x² + 25 + 10x = 16y - 96

The dimensions of the rectangle are, length = 5 inch and width = 6 inch.

What is rectangle?

A rectangle in Euclidean plane geometry is a quadrilateral with four right angles. It can alternatively be explained in terms of an equiangular quadrilateral—a term that refers to a quadrilateral whose angles are all equal—or a parallelogram with a right angle. A square is an irregular shape with four equal sides.

Let, the length of a rectangle is  7 inches less than twice the width, w, of the rectangle.

Suppose,

width = w = x, then,

length = l = 2x - 7

Since the area of the rectangle is 30 square inches.

We know that.

Area of rectangle = length x width

                        30 = (2x - 7) x (x)

                        30 = 2x^2 - 7x

     2x^2 - 7x - 30 = 0

2x^2 - 12x + 5x - 30 = 0

2x(x - 6) + 5(x - 6) = 0

      (2x + 5)(x - 6) = 0

⇒ 2x + 5 = 0,     x - 6 = 0

⇒ x = -5/2,           x = 6

Since length is not negative.

Therefore, w = 6.

So, l = 2(6) - 7 = 12 - 7 = 5

Hence, the length is 5 inches and the width is 6 inches.

The equation that represents each of the figure in slope intercept form are

equation of the left side - y = 3x + 2

equation of the right side - y = 3x - 4

equation of the top side - y = 5

equation of the bottom side - y = -1

The the slope intercept form has the formula

y = mx + c

where

m = slope

c = intercept

x = input variables

y = output variables

The left and right side's slopes require calculation however the top and bottom slope is zero

equation of the left side

The points used for the slope is gotten from the graph as (1. 5)  (0, 2)

m = (y₂ - y₁) / (x₂ - x₁)

substituting the values

= (2- 5) / (0 - 1)

= -3 / -1

= 3

writing the equation using points (0, 2)

(y - y₂) =  m(x - x₂)

y - 2 = 3(x - 0)

y = 3x + 2

equation of the right side

The points used for the slope is gotten from the graph as (5. 5)  (3, -1)

m = (y₂ - y₁) / (x₂ - x₁)

substituting the values

= (-1 - 5) / (3 - 5)

= -6 / -2

= 3

writing the equation using points (3, -1)

(y - y₂) =  m(x - x₂)

y - -1 = 3(x - 3)

y + 1 = 3x - 3

y = 3x - 4

Answer:

Step-by-step explanation:

V(x) = x3 + 2x2 - 11x - 12

To factor, you want 3 numbers that multiply to give -12 (the constant term) and add to give 2 (coefficient of the x2 term).  The answer is 4, -3, and 1: (4)(-3)(1) = -12, 4 + (-3) + 1 = 2.  So the volume polynomial factors to:

V(x) = (x+4)(x-3)(x+1)

Now the volume of a rectangular box is:

V = Length*Width*Height = (x+4)(x-3)(x+1)

So let's pick height = (x+1) = 4.5  (you could pick any one of the three factors).

x+1 = 4.5

x = 3.5

Length = (x+4) = 3.5+4 = 7.5

Width = (x-3) = 3.5 - 3 = 0.5

The box's dimensions are 7.5 m by 0.5 m by 4.5 m

The volume of the cylinder with radius(r) 7 inches and height(h) 9 inches

is 1384.74 cubic inches.

A cylinder is a three-dimensional solid object with two bases that are identically circular and are connected by a curving surface that is located at a specific height from the center.

Examples of cylinders are toilet paper rolls and cold beverage cans.

The volume of a cylinder is πr²h.

Curved surface area = 2πrh.

Total surface area = 2πr(h + r).

Given, a cylindrical shape of radius(r) 7 inches and height(h) 9 inches.

We know the volume of a cylinder is πr²h.

∴ The volume of this cylinder is

= π×(7)²×9 cubic inches.

= 441π cubic inches.

= 1384.74 cubic inches.

For the volume of a sphere, it is (4/3)πr³.

Using percent method we can solve the problem. Kal's acting class is 40 minutes long in total.

In which he practices lines about 28 minutes.

let "x minutes" be the total timing of kal's acting class .

Percent is always running between 0 to 100 where 0 % means nothing and 100% total about which we are considering the percent.

so, here x mintues is equal 100% timing

we have given that, kal practice lines for 28 minutes at his acting class and in percent form his timing is equal to 70% .

That's 70% time of entire acting class = 28 min

but we have to find the 100% of entire acting class i.e x minutes

Now, 70% time of entire class = 28 minutes

1% time of entire acting class = 28/70 minutes

100% time of entire acting class i.e x = ( 28/70)100

y = 1²-5*1+3 = 1-5+3 = -1

substituting the value x=2 we get,

y = 2²-5*2+3 = 4-10+3 = -3

substituting the value x=3 we get,

y = 3²-5*3+3 = 9-15+3 = -3

substituting the value x=4 we get,

y = 4²-5*4+3 = 16-20+3 = -1

substituting the value x=5 we get,

y = 5²-5*5+3 = 25-25+3 = 3

Answer:

each kiwi costs $2.40

Step-by-step explanation:

we set up our system of equations

x = bag of apples

y = kiwi

x + 16y = 43.7

x + 6y = 19.7

multiply any one of the equations by -1 to make x negative

-1(x+6y) = -1(19.7)

-x - 6y = -19.7

add the other equation and the new equation

   -x - 6y = -19.7

    x + 16y = 43.7

+ ____________

   10y = 24

divide by 10 both sides

y = 2.4

we can also look for the cost of each bag of apples

plug in the y value to an original equation

x + 16(2.4) = 43.7

simplify

x + 38.4 = 43.7

subtract 38.4 from both sides

The largest area of the rectangle is 2 square units.

We have a right angled isosceles triangle with hypotenuse 4 units.

so its base will be equal to the perpendicular  , let it be B

So we know ,

B² + P² = H²

2B² = H²

B²  = 16/2

B = 2√2

So base is equal to perpendicular = 2√2 units

Now let consider a rectangle inside the triangle with length 2x and the width y , and the area will become

A = 2xy  ....(1)

we see from the figure the length of the perpendicular AD drawn on the hypotenuse is

BD² + AD² = AB²

AD² = AB² - BD²

      = 8 - 4

AD² = 4

AD = 2 units

Now we see triangle ABD and AEG are similar to each other , So

AD/BD = AG/GE

2/2 = 2-y/x

therefore

x = 2-y

put this value in eqn (1)

A = 2(2-y)y

A = 4y - 2y²

Now to maximize the area we take the derivative of the equation and then put it equal to zero

∴ 4 - 4y = 0

y = 1

∴ x = 2-y = 2-1 = 1 units

So area will be maximum when length and width are 1 units each.

therefore , largest area (A) of the rectangle is  = 2xy = 2 square units.
