Answer:

  AC ≈ 6.8 cm

Step-by-step explanation:

For legs a and b of a right triangle with hypotenuse c, the Pythagorean theorem tells us ...

  a = √(c² -b²)

Using this relation, we can find legs CE and AE.

  CE = √(3² -2²) = √5

  AE = √(5² -2²) = √21

AC is the sum of these two lengths:

  AC = AE +EC = √21 +√5

  AC ≈ 6.8 cm

The amount of oil consumed in 5 hours is 120.5 barrels.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given is an equation, of fuel consumption in a factory from 6 am to 6 pm,

The equation =

f(t) = 0.9t³-0.6[tex]t^{0.5}[/tex]+10

where t is the time in hours after 6 am and f(t) is the number of barrels of fuel oil.

We need to find the how much oil is consumed by 11 am,

So, the hours between 11 am to 6 am = 11-6 = 5 hours

So, we need to find the oil consumption in 5 hours, so for the same put t = 5, in the equation,

f(5) = 0.9(5)³-0.6[tex](5)^{0.5[/tex]+10

= 112.5-2+10

= 120.5

Hence, the amount of oil consumed in 5 hours is 120.5 barrels.

The p-value of the test is 0.2.

Step-by-step explanation:

Using the alternative hypothesis that µ ≠ 531, Amy found a t-test statistic of 1.311.

Alternative hypothesis means that e have a two-tailed hypothesis test.

Sample 30 citizens. Amy found a t-test statistic of 1.311.What is the p-value of the test statistic?

Thus, we have a two-tailed test with 30 - 1 = 29 degrees of freedom and t = 1.311. So, using a t-distribution calculator, the p-value of the test is 0.2.

The difference between the cash price and the initial deposit in hire purchase is known as [tex]_\( \text{Principal} \)_[/tex].

In hire purchase transactions, buyers can acquire goods by making an initial down payment and paying the remaining amount in installments. The difference between the total cost of the item and the initial deposit is a crucial concept known as the [tex]_\( \text{Principal} \)_[/tex] in mathematical terms. Let's explore this in detail.

In the context of hire purchase, the total cost of the item is often referred to as the cash price. It represents the actual value of the item without considering any interest or finance charges. On the other hand, the initial deposit, also called the down payment, is the amount paid upfront by the buyer to secure the item.

Now, let's introduce some variables to help us understand this concept mathematically:

- Let CP be the cash price of the item.

- Let D be the initial deposit made by the buyer.

The difference between the cash price and the initial deposit is given by:

[tex]\[ \text{Principal} = CP - D \][/tex]

The Principal is the amount that remains to be paid off in installments, and it serves as the basis for calculating the subsequent monthly or periodic payments in a hire purchase agreement.

The Principal is critical because it determines the total amount the buyer will end up paying for the item. It also affects the duration of the hire purchase agreement, as the buyer's installments are typically spread over a specific number of months or years.

Answer:

f(x,y) = [tex]e^{xy}[/tex] is maximum at x = 2 and y = 2 and f(2,2) = [tex]e^{4}[/tex]

Step-by-step explanation:

Since f(x,y) = [tex]e^{xy}[/tex] and x³ + y³ = 16, Ф(x,y) = x³ + y³ - 16

df/dx = y[tex]e^{xy}[/tex], df/dy = x[tex]e^{xy}[/tex], dФ/dx = 3x² and dФ/dy = 3y²

From the method of Lagrange multipliers,

df/dx = λdΦ/dx and df/dy = λdΦ/dy

y[tex]e^{xy}[/tex] = 3λx² (1) and  x[tex]e^{xy}[/tex] = 3λy² (2)

multiplying (1) by x and (2) by y, we have

xy[tex]e^{xy}[/tex] = 3λx³ (4) and  xy[tex]e^{xy}[/tex] = 3λy³ (5)

So,  3λx³ = 3λy³

⇒ x = y

Substituting x = y into the constraint equation, we have

x³ + y³ = 16

x³ + x³ = 16

2x³ = 16

x³ = 16/2

x³ = 8

x = ∛8

x = 2 ⇒ y = 2, since x = y

So, f(x,y) = f(2,2) = [tex]e^{2 X2}[/tex] = [tex]e^{4}[/tex]

We need to determine if this is a maximum or minimum point by considering other points that fit into the constraint equation.

Since x³ + y³ = 16 when x = 0, y is maximum when y = 0, x = maximum

So, 0³ + y³ = 16

y³ = 16

y = ∛16

Also, when y = 0, x = maximum

So, x³ + 0³ = 16

x³ = 16

x = ∛16

and f(0,∛16) = [tex]e^{0X\sqrt[3]{16} } = e^{0} = 1[/tex].

Also, f(∛16, 0) = [tex]e^{\sqrt[3]{16}X0 } = e^{0} = 1[/tex].

Since f(0,∛16) = f(∛16, 0) = 1 < f(2,2) = [tex]e^{4}[/tex]

f(2,2) is a maximum point

Answer: (2,6) (-3,11)

Step-by-step explanation:

At the intersection, y=9- 6/x and y+x = 8 are equal to each other

y + x = 8  is the same as y=8-x

Sub this into y = 9 - 6/x

8 - x = 9 - 6/x

Multiply everything by x:

8x - x^2 = 9x - 6

x^2 + x - 6 = 0

(x-2)(x+3) = 0

x = 2   (so y = 9 - 6/x so y = 9 - 6/2 =6)

x = -3 (so y = 9-6/x so y = 9-6/-3 = 11)

The coordinates of two points will be ; (2,6) and (-3,11).

It is given that the curve y = 9 - (6 / x) and line y + x = 8.

Find the coordinates of two points.

What is the general equation of line ?

General equation is given by ; y = mx + c.

At the intersection,

y = 9 - 6/x ----------- (Equation 1)

and y + x = 8 are equal to each other.

y + x = 8 can be written as y = 8-x.

Substitute this into Equation 1.

8 - x = 9 - ( 6/x )

Multiply both sides by x ;

8x - [tex]x^{2}[/tex] = 9x - 6

[tex]x^{2}[/tex] + x - 6 = 0

This can be written as ;

(x-2) (x+3) = 0

So we get values of x ;

i.e., x = 2  , -3

For , x = 2

y = 9 - 6/x

⇒ y = 9 - (6/2)

 ⇒ y = 6

For , x = - 3

⇒ y = 9 - (6/x)

⇒ y = 9 - (6/ -3)

⇒ y = 11

Thus , the coordinates of two points will be ; (2, 6) and (-3,11).

Answer:

y = -7x + 57

Step-by-step explanation:

If the line is parallel, it will have the same slope. So, this line will also have a slope of -7.

Use y = mx + b, plug in the slope and given point, and solve for b:

y = mx + b

-6 = -7(9) + b

-6 = -63 + b

57 = b

Plug in the slope and y intercept into y = mx + b:

y = mx + b

y = -7x + 57

So, the equation is y = -7x + 57

Given:

In quadrilateral ABCD, angle B=90° , AB=9m, BC=40m, CD=15m, DA=28m.

To find:

The area of the quadrilateral ABCD.

Solution:

In quadrilateral ABCD, draw a diagonal AC.

Using Pythagoras theorem in triangle ABC, we get

[tex]AC^2=AB^2+BC^2[/tex]

[tex]AC^2=9^2+40^2[/tex]

[tex]AC^2=81+1600[/tex]

[tex]AC^2=1681[/tex]

Taking square root on both sides, we get

[tex]AC=\sqrt{1681}[/tex]

[tex]AC=41[/tex]

Area of the triangle ABC is:

[tex]A_1=\dfrac{1}{2}\times base\times height[/tex]

[tex]A_1=\dfrac{1}{2}\times BC\times AB[/tex]

[tex]A_1=\dfrac{1}{2}\times 40\times 9[/tex]

[tex]A_1=180[/tex]

So, the area of the triangle ABC is 180 square m.

According to the Heron's formula, the area of a triangle is

[tex]Area=\sqrt{s(s-a)(s-b)(s-c)}[/tex]

where,

[tex]s=\dfrac{a+b+c}{2}[/tex]

In triangle ACD,

[tex]s=\dfrac{28+15+41}{2}[/tex]

[tex]s=\dfrac{84}{2}[/tex]

[tex]s=42[/tex]

Using Heron's formula, the area of the triangle ACD, we get

[tex]A_2=\sqrt{42(42-28)(42-15)(42-41)}[/tex]

[tex]A_2=\sqrt{42(14)(27)(1)}[/tex]

[tex]A_2=\sqrt{15876}[/tex]

[tex]A_2=126[/tex]

Now, the area of the quadrilateral is the sum of area of the triangle ABC and triangle ACD.

[tex]A=A_1+A_2[/tex]

[tex]A=180+126[/tex]

[tex]A=306[/tex]

Therefore, the area of the quadrilateral ABCD is 306 square meter.

Answer:

  e. Exponential growth occurs when a population increases at a fixed percentage of every generation.

Step-by-step explanation:

Exponential growth occurs when the amount of increase is proportional to the population. That is, the increase is a fixed percentage of the population in any given time period (generation).

__

Many populations appear to have exponential growth when resources are effectively unlimited. The growth can be rapid, but isn't always. At some point, the population generally finds a limit to its growth, which then ceases to be exponential.

A function describing population growth that is jointly proportional to population and available resources is called a logistic function. It has an exponential component, but is not an exponential function.

Sales tax is charged on the subtotal (amount before tax).

First, find the subtotal by adding up all of the amounts.

4(675) + 2(110) + 5(41) + 6(135) + 230(2.50)

2700 + 220 + 205 + 810 + 575

Total = 4510

Next, we need to find 7% of 4510. That number is the sales tax.

0.07 x 4510 = 315.70

Sales Tax = $315.70

Total Amount (with tax) = $4825.70
