Answer:

From the given information, the value of n is 1. By using that information, the measure of JL is 29.

Step-by-step explanation:

For this problem, we have to not only find the value of n but, we also have to find the value of JL. We are given information in this problem.

ΔABC ≅ ΔJKL

AC = 10n + 19

JL = 9n + 20

From this information, we can conclude that AC and JL are congruent meaning they are equal in measure. So, let's set up an equation where they set equal to each other.

10n + 19 = 9n + 20

Subtract 9n from 10n.

n + 19 = 20

Subtract 19 from 20.

n = 1

So, the value of n is 1. We can use this to find the value of JL.

JL = 9(1) + 20

JL = 9 + 20

JL = 29

Answer:

JL is equal to 29

Step-by-step explanation:so JL= 29 is the answer

Answer:

Step-by-step explanation:

A complex number in its rectangular form is expressed as x+iy where x is the real part of the complex number and y is the imaginary because it is attached to the imaginary number i.

Given the complex number 4-5i, comparing the complex number with x+iy

4 = x and iy = -5i

Hence x = 4 and y = -5.

Since x is the real part of the complex number x+iy, hence 4 will be the real part of the complex number 4-5i based on comparison.

Answer:

Lulu= £81

Ruby=£108

Emma=£ 72

Step-by-step explanation:

Let Lulu's money be x

Let Ruby's money be y

Let Emma's money be z

The total money they went shopping with is = £261

So

x+y+z= 261

Lulu spent 2/3 of her money Ruby spent 1/2 of her money and Emma spent 3/4 of her money.

Money spent by each

Lulu= 2/3x

Ruby=1/2y

Emma= 3/4z

Each of them spent the same amount of money.

2/3x= 1/2y= 3/4z

2/3x= 1/2y

x(2*2)/3 = y

4/3(x) = y

2/3x=3/4z

x(2*4)/(3*3)= z

8/9x= z

x+y+z= 261

x+4/3x+8/9x= 261

9x +12x +8x= 2349

29x= 2349

X= 81

4/3(x) = y

4/3(81) = y

108= y

8/9x= z

8/9(81)= z

72= z

Answer:

a) The profit function is [tex]P(x) = -x^{2}+60\cdot x -100[/tex], b) The marginal profit function is [tex]P'(x) = -2\cdot x + 60[/tex].

Step-by-step explanation:

a) Let be [tex]C(x) = 30\cdot x + 100[/tex] (cost function) and [tex]R(x) = -x^{2}+90\cdot x[/tex] (revenue function), the profit function is found by subtracting the cost function from the revenue function. That is:

[tex]P(x) = R(x)-C(x)[/tex]

[tex]P(x) = -x^{2}+90\cdot x -(30\cdot x + 100)[/tex]

[tex]P(x) = -x^{2}+90\cdot x -30\cdot x -100[/tex]

[tex]P(x) = -x^{2}+60\cdot x -100[/tex]

b) The marginal profit function is the first derivative of the profit function:

[tex]P'(x) = -2\cdot x + 60[/tex]

At the point of the least cost of fencing the cost function has a zero

derivative.

Reasons:

Shape of the pen = Rectangular

Area of the pen = 24 yd²

Cost of material on one side of the fence = $6 per yard

Cost of material on the remaining three sides = $3 per yard

Required:

The least cost of fencing the pen

Solution:

The least cost is a minimum value of the cost function

Let L represent the length of the fence and let W represent the width of the fence

We have;

The perimeter of the fence = 2·L + 2·W

The area of the pen, A = L × W = 24

One of the length, L, of the fence costs $6 per yard and the other length L,

of the opposite side costs $3 per yard.

The cost of fencing, C  3 × 2·W + 3 × L + 6 × L = 6·W + 9·L

C = 6·W + 9·L

[tex]\displaystyle W = \mathbf{\frac{24}{L}}[/tex]

Which gives;

[tex]\displaystyle C = 6 \cdot \frac{24}{L} + 9 \cdot L = \frac{144}{L} + 9 \cdot L = \mathbf{\frac{144 + 9 \cdot L^2}{L}}[/tex]

The shape of the above function is concave upwards.

At the minimum value, we have;

[tex]\displaystyle \frac{dC_{min}}{dL} = \frac{d}{dL} \left(\frac{144}{L} + 9 \cdot L\right) = 9 - \frac{144}{L^2} = 0[/tex]

Which gives;

[tex]\displaystyle \frac{144}{L^2} = 9[/tex]

[tex]\displaystyle \frac{144}{9} = L^2[/tex]

By symmetric property, we have;

[tex]\displaystyle L^2 = \frac{144}{9}[/tex]

[tex]\displaystyle L = \sqrt{ \frac{144}{9}} = \frac{12}{3} = 4[/tex]

The length of the fence that gives the least cost, L = 4 yards

[tex]\displaystyle At \ L = 4, \ W = \frac{24}{4} = 6[/tex]

The width of the fence at least cost, W = 6 yards

Cost, C = 6·W + 9·L

Least cost, [tex]C_{min}[/tex] = 6 × 6 + 9 × 4 = 72

The least cost of the fencing, [tex]C_{min}[/tex] = $72.00

Answer:

v (E) = √(2E/m)

Step-by-step explanation:

From the question given:

E = ½mv²

E is the kinetic energy

m is the mass of object

v is the velocity.

To find a model v(E) for the velocity of the object, we simply make V the subject of the above equation.

This can be obtained as follow:

E = ½mv²

Cross multiply

mv² = 2E

Divide both side by m

v² = 2E/m

Take the square root of both side

v = √(2E/m)

Therefore, the model v(E) for the velocity of the object is given by:

v (E) = √(2E/m)

Answer:

The height of the triangle is 6.4cm

Step-by-step explanation:

- If the triangle has a side that measures 12.5cm, it means that two of its sides are equal in length.

Which is equivalent to the description of an isosceles triangle.

To find the height, use the equation of the area.

Area = (Base * height) / 2

- We know the value of the area and its shorter side that could be the base.

40cm = (12.5 cm * h) / 2

- Clearing the height would give that:

80cm / 12.5cm = h

h = 6.4cm

The height of the triangle is 12.5cm

A triangle is a plane figure with edges that are all straight with three sides and three angles.

The formula for calculating the area of a triangle is;

[tex]\mathbf{Area = \dfrac{1}{2}\times Base \times Height}[/tex]

Given that:

The area = 40 cm²

Since the diagram for the triangle is not given;

∴

Using the formula form above:

[tex]\mathbf{40.0 cm^2 = \dfrac{1}{2}\times 12.5 cm \times Height}[/tex]

[tex]\mathbf{40.0 cm^2 \times 2 = 1\times 12.5 cm \times Height}[/tex]

[tex]\mathbf{80.0 cm^2 = 12.5 cm \times Height}[/tex]

[tex]\mathbf{Height = \dfrac{80.0 cm^2}{ 12.5 cm} }[/tex]

Height of the triangle = 6.4 cm

Therefore, we can conclude that the height of the triangle = 6.4 cm

Step-by-step explanation:

Given

[tex]n^2 + \frac{5}{2}n[/tex]

Required

(a) Make a perfect square trinomial

(b) Write as binomial square

Solving (a)

Let the missing part of the expression be k;

This gives

[tex]n^2 + \frac{5}{2}n + k[/tex]

To solve for k, we need to square half the coefficient of n;

i.e. Since the coefficient of n is [tex]\frac{5}{2}[/tex], then

[tex]k = (\frac{1}{2} * \frac{5}{2})^2[/tex]

[tex]k = (\frac{5}{4})^2[/tex]

[tex]k = \frac{25}{16}[/tex]

Hence;

[tex]n^2 + \frac{5}{2}n + k[/tex] = [tex]n^2 + \frac{5}{2}n + \frac{25}{16}[/tex]

Solving (b)

[tex]n^2 + \frac{5}{2}n + \frac{25}{16}[/tex]

Answer:

The probability is 0.0643 to 4 decimal places

Step-by-step explanation:

To calculate this probability, we find the z-score

Mathematically;

z-score = (x-mean)/SD

where in the question;

x = 46.3

mean = 55.1

SD = 5.8

Plugging these values, we have;

z-score = (46.3-55.1)/5.8 = -8.8/5.8 = -1.52

The probability we want to calculate is;

P(z < -1.52)

We can get this answer by using the standard normal distribution table;

Thus from the table, we have;

P(z < -1.52) = 0.064255 which is 0.0643 to 4 decimal places

Answer:

y = - 14/3 +7x/3

Step-by-step explanation:

The reason for my answer is because let us move the -3y so it is before the equal sign. Let us also move 7x to the other side but make it so 14 would be to the right side of the equal sign. Now, that would mean 7x would be after 14. Our equation is now -3y=14-7x. We need to divide both sides of the equation by -3. There, we just divided -3y by 3 which equals to y. 14 divided by -3 equals to -14/3. -7x divided by -3 would equal to +7x/3. Finally, we get the answer of y = - 14/3 +7x/3.

Answer:

Step-by-step explanation:

● 7x-3y = 14

This a 1st degree equation with two variables.

● 7x-3y = 14

Substract 7x from both sides

● 7x-7x -3y = 14-7x

● -3y = 14-7x

Mulitply both sides by -1

● (-1)×(-3y) = (-1)×(14-7x)

● 3y = -14+7x

● 3y = 7x+14

Divide both sides by 3

● 3y/3 = (7x+14)/3

● y = (7/3)x + 14/3

There are infinite solutions for this equation. Keep replacing x with value and the output will change everytime.
