The length of the square paving is the base unit to which the area of the

and patio and the border are evaluated.

Correct response:

Let s represent the size of the square paving, we have;

Area of the patio = s·x × s·y = s²·x·y

New area = (2·s + s·x) × (2·s + s·y) = 4·s² + 2·s²·y + 2·x·s² + s²·x·y

Area of the border = 4·s² + 2·s²·y + 2·x·s² = s²·x·y

2·s²·(2 + y + x) = s²·x·y

2·(2 + y + x) = x·y

4 + 2·y + 2·x = x·y

x·y - 2·x = 4 + 2·y

x·(y - 2) = 4 + 2·y

Which by using  gives;

[tex]x = \mathbf{ \dfrac{4 + 2 \cdot y }{y- 2}}[/tex]

Answer:

  (a) 7.1

  (b) (5/2, 3/2)

  (c) 2

  (d) y = -x +4

Step-by-step explanation:

The length of AC is found using the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((5 -(-2))² +(-1 -0)²) = √(49 +1) = 5√2 ≈ 7.1

The length of AC is about 7.1.

The midpoint has coordinates that are the average of the end point coordinates.

  midpoint BC = (B + C)/2 = ((0, 4) +(5, -1))/2 = (5, 3)/2

  midpoint BC = (5/2, 3/2)

__

The slope is found using the slope formula.

  m = (y2 -y1)/(x2 -x1)

For points A(-2, 0) and B(0, 4), the slope of the segment between them is ...

  m = (4 -0)/(0 -(-2)) = 4/2 = 2

The slope of AB is 2.

__

The slope of line BC is found in the same was as for AB.

  m = (-1 -4)/(5 -0) = -5/5 = -1

The y-intercept of the line is point B, at y=4. So, the equation of line BC is ...

  y = mx +b . . . . . where m is the slope, and b is the y-intercept

  y = -x +4

Answer: 9

Step-by-step explanation:

Add 7 to 74, which gives you 81. Then divide by 9 for the value of w and you get 9.

Answer:

w = 9

Step-by-step explanation:

Isolate variable by adding 7 to both sides

9w = 81

Divide both sides by 9 to get w alone

w = 9

Check

9(9) - 7 =74

81-7 = 74

Answer:

f^-1(x) = ( x + -1 )³

Step-by-step explanation:

f(x) = ∛x + 1

y  = ∛x + 1

we have to make x the subject to find the inverse

y  = ∛x + 1

y - 1 = ∛x

( y - 1 )³ = x

so Inverse: f^-1(x) = ( x + -1 )³

[tex]3(7550)=7550e^{0.0725\cdot t}\implies \cfrac{3(7550)}{7550}=e^{0.0725t}\implies 3=e^{0.0725t} \\\\\\ \log_e(3)=\log_e\left( e^{0.0725t} \right)\implies \ln(3)=0.0725t \\\\\\ \cfrac{\ln(3)}{0.0725}=t\implies 15.15327\approx t\implies 15\approx t[/tex]

It will take approximately 9.55 years (rounded to the nearest year) for the money to triple.

Here, we have,

To determine how long it will take for the money to triple, we need to use the continuous compound interest formula:

A = P *[tex]e^{rt}[/tex],

where:

A = final amount (triple the initial amount)

P = principal amount (initial deposit)

e = Euler's number (approximately 2.71828)

r = interest rate

t = time (in years)

In this case, we have:

P = $7550

r = 7.25% = 0.0725 (converted to decimal)

A = 3P (triple the initial amount)

Substituting these values into the formula, we have:

3P = P *[tex]e^{rt}[/tex]

Dividing both sides of the equation by P, we get:

3 = [tex]e^{rt}[/tex]

To isolate the variable t, we take the natural logarithm (ln) of both sides:

ln(3) = ln[tex]e^{rt}[/tex]

Using the logarithmic property that ln(eˣ) = x, we have:

ln(3) = rt * ln(e)

Since ln(e) = 1, the equation simplifies to:

ln(3) = rt

Now, we can solve for t by dividing both sides by r:

t = ln(3) / r

Substituting the values:

t = ln(3) / 0.0725

Using a calculator or software, we find:

t ≈ 9.55 years (rounded to two decit will take approximately 9.55 years (rounded to the nearest year) for the money to triple. deimal places)

Therefore, it will take approximately 9.55 years (rounded to the nearest year) for the money to triple.

x = 72

Step-by-step explanation:

A circle is 360 degrees

2x-61+ x-11 + 3x = 360

Combine like terms

6x-72=360

Add 72 to each side

6x-72+72 = 360+72

6x =432

Divide each side by 6

6x/6 = 432/6

x =72

The cost of 2 pair of boots is given by A = $ 60.90

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the cost of 2 pair of boots be A

Now , the cost of pair of boots = 145 % the cost of pair of sneakers

Substituting the values in the equation , we get

The cost of pair of sneakers = $ 21

So , the cost of pair of boots = ( 1.45 ) x 21

The cost of pair of boots = $ 30.45

Now , the cost of 2 pair of boots A = 2 x cost of pair of boots

On simplifying , we get

The cost of 2 pair of boots A = $ 60.90

Hence , the cost of 2 pair of boots is $ 60.90
