Answer:

Step-by-step explanation:

Using Linear equation we get , Travis and Natalie's combined hourly wages are $135 and $137.

Combined Natalie earns $2 more an hour than Travis.

Natalie works 40 hours

Travis works 35 hours

for his or her work Salary difference = $755

we have to find out what percentage each of them contributes per hour.

Let Travis earn in dollars per hour = x

So if he works 35 hours his earnings in dollars

= 35x

Natalie can earn in dollars per hour = x+2

So If she works 40 hours, her income will be in dollars = 40x + 80 [use distribution]

The income difference will be:

⇒ 40x + 80 -35x = 755

=> 5x = 675 => x = 135

So Travis' hourly rate = $135

Natalie's hourly rate = 135+2= $137

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

x² + 10x - 16y = -121

Hence , the equation of parabola is ( x + 5 )² = 16 ( y - 6 )

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

How likely is it that a student chosen at random will have an IQ of 115 or higher?

Since half should be over the normal of 100 (by evenness), this implies 50 - 34.13 = 15.87 (%) has an intelligence level score over 115.

Which level of understudies might have scored either higher than 90 or lower than 70?

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 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.

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).

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

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 equation  of the line  in slope-intercept forms expressed as: y = y = 1x + 3

How to Write the Equation of a Line?

To wrote the equation of a line in slope-intercept form, first, find the slope (m) of the line, determine the y-intercept (b) of the line, then substitute the values into y = mx + b (equation in slope-intercept form).

Using two points on the line, (0, 3) and (4, -1):

Slope (m) = change in y / change in x = (3 - -1)/(0 - 4)

Slope (m) = 4/-4

Slope (m) = -1

The slope of the line is m = -1.

Find the y-intercept (b) by substituting one point, (x, y) = (0, 3), and m = -1 into y = mx + b and solve for b:

3 = 1(0) + b

3 = 0 + b

b = 3

Write the equation of the line by substituting b = 3 and m = -1 into y = mx + b:

y = 1x + 3

Thus, the equation in slope-intercept form of the line is expressed as: y = 1x + 3
