a) The number of widgets that Widgets"R'U must sell to reach the break-even point is 2,082 units.

b) Using the expense and revenue equations, if Widgets'R'Us sells 5,430 widgets, their profit will be $8,745.

The profit equation is total revenue minus total costs.

The profit equation shows that profit is a function of the difference between the total revenue realized from sales and services less the total costs involved in rendering the services or delivering the goods.

At the break-even point, the total revenue equals the total costs.  Therefore, there is no profit or loss.

The total cost function, E = 1.48q + 4,830

The total revenue function, R = 3.98q

To break even, the quantity to be sold, q, 1.48q + 4,830 = 3.98q

-2.32q = -4,830

q = 2,082

When q = 5,430:

Profit = 3.98q - (1.48q + 4,830)

= 3.98(5,430) - (1.48 x 5,430 + 4,830)

= 21,611.4 - (12,866.4

= 8,745

If the two sides of isosceles triangle are (x+2) cm and third side is (x+6) cm. if perimeter is 385 cm, then the value of x is 125 .

We know that the Perimeter of the triangle is equal to the sum of the lengths of all its sides.

the two sides of isosceles triangle are = (x+2) cm ;

the length of third side of triangle is = (x+6) cm ;

So , we have:

⇒ x + 2 + x + 2 + x + 6  = 385

Simplifying and solving for x:

⇒ 3x + 10 = 385 ;

⇒ 3x = 385 - 10 ;

⇒ 3x = 375 ;

⇒ x = 375/3 = 125

n=212.9

Step-by-step explanation:

= 4068 + 55n/60 + n = 64.1

= 4068 + 55n = 64.1 ( 60 + n )

= 4068 + 55n = 3846 + 64.1n

= 55n - 64.1 = 3846 - 4068

The rate at which the number of wolves in the forest is changing at t = 7 weeks is 20.932 wolves per week.

To find the rate at which the number of wolves in the forest is changing at t = 7 weeks, we can evaluate the function E(t) at t = 7:

E(7) = 31 cos(0.11 * 7^2) = 31 cos(4.97)

Using a calculator, we can find that cos(4.97) = 0.672. So,

E(7) = 31 X 0.672 = 20.932

2) The speed of the current is; 2.79 km/ hr

1) Let s represent the team score and as such we have;

Michaela scored s/5 (one fifth of the team's points)

Aleah scored s/10 (one tenth of the team's points)

These total scores is 42. Thus;

s/5 + s/10 = 42

Multiply through by 10 to get;

2s + s = 420

3s = 420

s = 420/3

s = 140

The team scored 140 points.

Thus;

Michaela scored;

140/5 = 28 points

Aleah scored;

140/10 = 14 points.

2) Let the speed of current be x km/ hr

Thus;

Upstream speed  = ( 6.5 - x) km/ hr

The measure of angle x = 50° and y = 40°.

A angle is formed when two rays intersect. The point of intersection is called the vertex point .

Given is that in rectangle ABCD in which -

m ∠EAB = (4x+6)°  

m ∠DEC = (10−11y)°

m ∠EBC = 60°

We can write -

∠AEB = ∠DEC = (10 - 11y)°

Now, we know that the external angle is the sum of two interior opposite angles. So -

∠EBC = (4x + 6) + (10 - 11y)

4x - 11y + 16 = 60

4x - 11y = 54

and

(4x + 6) + (10 - 11y) + 30 = 180

4x - 11y = 144

The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1, then it is known as a linear equation in one variable. A linear equation can have more than one variable. If the linear equation has two variables, then it is called linear equations in two variables and so on.

A system consisting of exactly one equation can have no solution. for example.

[tex]2 x[/tex][tex]=\frac{1}{2}(4 x+2)+1[/tex]

on we solve this, we get,

The integral is given as - ∫4/(2x-1) dx

Substitute u = (2x - 1) → du/dx = 2 → dx = 1/2 du -

⇒ 2 ∫ 1/u du

The standard integral is -

Variance and standard deviation are measures of variability that are appropriate and possible to calculate for variables measured on an interval or ratio scale of measurement.

Interval scales have a true zero point, meaning that a difference of zero on the scale represents a lack of the characteristic being measured (e.g. temperature measured in degrees Celsius). Ratio scales are similar to interval scales, but also have a meaningful zero point, meaning that a value of zero on the scale represents a complete absence of the characteristic being measured (e.g. height measured in meters).

Variance and standard deviation can be calculated for interval and ratio variables because these scales provide meaningful differences and ratios between values. The calculation of variance involves finding the average squared difference between each value and the mean of the values, while standard deviation is the square root of the variance. Both variance and standard deviation provide information about how spread out the values of a variable are and are useful in statistical analysis.

On the other hand, nominal and ordinal scales only provide categories or rank order for values, without any meaningful differences or ratios between values. As such, it is not appropriate or possible to calculate variance or standard deviation for variables measured on nominal or ordinal scales.

The equation of a parabola can be drawn given a focus of (5, 3 ) and a directrix of x = − 1.

The equation of the parabola is:

A parabola is an equation of a curve, such that any point on the curve is equidistant from a fixed point called the focus and a fixed line called the directrix of the parabola.

The equation of a parabola:

y = a(x-h)^2 + k

We have,

The standard form:

(x - h)² = 4p (y - k)

where the focus is (h, k + p) and the directrix is y = k - p.

Now,

(h, k + p) = (5, 3)

h = 5

k - p = -1

k + p = 3

Now,

k - p = -1

k = -1 + p

substituting

k + p = 3

-1 + p + p = 3

-1 + 2p = 3

2p = 3 + 1

2p = 4

p = 2

k = -1 + 2

k = 1

Now,

The equation of the parabola.

(x - h)² = 4p (y - k)

(x - 5)² = 4 x 2 (y - 1)

(x - 5)² = 8 (y - 1)

The area of the triangle GBC for the given condition of midpoint with a given area of ΔGMN = 6 equals 24.

In triangle ABC,

M is the midpoint of AB , N is the midpoint of AC

⇒ MN is parallel to BC

G is the intersection of BN and CM.

⇒ G is the centroid.

Centroid divides the line segment BN  and CM in the ratio

BG : GN = 2 : 1

CG : GM = 2 : 1

In ΔGMN and ΔGBC ,

MN || BC , BN and CM are transversal.

∠NMG ≅∠BCG  ( alternate angles)

∠MNG ≅ ∠CBG  ( alternate angles)

∠MGN ≅∠BGC ( vertically opposite angles )

By AA corollary,

ΔGMN is similar to ΔGBC

BG : GN = CG : GM

Area of triangle GMN = 6

Area of ΔGBC  / Area of ΔGMN = Square of the sides

⇒ Area of ΔGBC / 6 = ( 2 / 1 )²

⇒ Area of ΔGBC = 4 ( 6)

⇒ Area of ΔGBC = 24

Therefore, the area of the triangle GBC is equal to 24.

The value of common difference, d is equals to the one. The value of common ratio, r is equals to the 4/3.

We have, an arithmetic sequence and second is geometric sequences. The common difference between the two consecutive terms of AP sequence is "d" and d ≠ 0 and the common ratio between two consecutive terms of geometric sequence is "r". Let the AP sequence is represented by aₙ and G.P sequence is represented by Tₙ. First term of both sequences = 9 , i.e., a₁ = a = T₁ = 9

The nth term of A.P is written as

aₙ = a + (n - 1)d so, a₄ = a + 3d and a₈ = a + 7d

The nth term of G.P is , Tₙ = ar⁽ⁿ⁻¹⁾

so, T₂ = ar , T₃ = ar²

Now, a₄ = T₂ => ar = a + 3d

=> 9r = 9 + 3d --(1)

a₈ = T₃ => ar² = a + 7d

=> 9r² = 9 + 7d --(2)

from(1) and (2) , 3(r - 1) = d , 9r² = 9 + 7(r -1)3

=> 9r² = 9 + 21r - 21

=> 9r² = 21r - 12

=> 9r² - 21r + 12 = 0

=> r = 1, 4/3

then, plugging the value of r in equation (1),

d = 3( r - 1)

=> d = 3( 0) when r = 1

=> d = 0, but it is not possible as d≠0

and d = 3( 4/3 - 1) = 1 when r = 4/3

So, required values of d and r are 1 and 4/3.
