what are the area and perimeter of 7in 16in​

Answers

The Area and Perimeter of the rectangle is 112 Inches² and 46 Inches respectively.

Suppose in question they are talking about rectangle.

So, let

Length (l) of rectangle  = 16 Inches

Width (w) of rectangle  =   7 Inches

As we have both sides of rectangle now we will determine the value of area and perimeter of rectangle.

Area of rectangle = l × w

                              = 16 × 7

                              = 112 Inches²

Perimeter of rectangle = 2( l + w )

                                      = 2( 16 + 7 )

                                      = 2 × 23

                                      = 46 Inches

Let f(x)=x-2 and g(x)=x²-3 x+2 . Perform each function operation and then find the domain. -2 g(x)+f(x)

Answers

The outcome of -2 g(x) + f(x) is 4 x -2  x ² and the domain is  [ 0 , 2 ] .

Given,

f (x) = x - 2 and g (x) = x² - 3 x + 2

The question states to find the summation of the function f, that is, f (x) = x - 2, and function g, that is, g (x) =  x² - 3 x + 2

Performing the addition operation on these functions is just like simple addition.

This means that when we add the two functions f (x) and g (x), we get

f (x) + g (x) = x - 2 + x² - 3 x + 2

=> f (x) + g (x) = x ² - 2 x

This implies that the summation or addition of the two functions f (x) and g (x) gives x ² - 2 x

needed result = -2 g(x) + f(x) = -2 ( x² - 2 x ) = -2  x ² + 4x = 4 x -2  x ²

To find domain,

y = 4 x -2  x²

=> 4x -2 x²  ≥   0

=> 2 x * ( 2 - x )  ≥   0

=> 2 x ≥ 0 and 2 - x  ≥   0

=>x  ≤ 2 and  x ≥   0

=> the final Domain = [ 0 , 2 ]

Therefore, we get the result of -2 g(x) + f(x) as 4x -2  x ² and the domain as  [ 0 , 2 ] .

Where is the point (-3,1) located when it is translated four units left and two units up 

Answers

Answer:

-5,3. You crawl before you can walk.

Step-by-step explanation:

Answer:

(-7, 3)

Step-by-step explanation:

Original point: (-3, 1)

So original x = -3
4 units left means x coordinate is decreased by 4
So, new x-coordinate = -3 - 4 = -7

Original y coordinate = 1
2 units up means y coordinate increases by 1
So new y-coordinate = 1 + 2 = 3

En 1999 la ciudad tenía 300 gatos callejeros y se ha demostrado que la cantidad de gatos crece un 10% año con año, ¿Cuántos gatos callejeros hay en la actualidad?

Answers

Number of cats cannot be a decimal value, therefore, Total number of stray cats in the city today are 2686, rounded off from 2686.29.

As per the question statement, a certain city had 300 stray cats in 1999, and the number of cats are growing by 10% every year since then.

We are required to calculate the total number of stray cats in the city today.

To do so, we will need to know the formula of compound interest which goes as [tex]A=[P*(1+\frac{R}{100})^n][/tex]

Where, A = Final Amount i.e., (Principle + Interest).

P = Principle on which Interest in compounded

R = Rate of Compound Interest per annum

n = Time period of interest.

Here, (P = 300), (R = 10) and [n = (2022-1999) = 23]

Using these values of P, R and n in the above-mentioned formula to calculate the amount in the case of compound interest, we get,

Total number of stray cats in the city today (T) = [tex][300*(1+\frac{10}{100})^{23} ][/tex]

[tex]or, T=[300*(\frac{100+10}{100})^{23} ]\\or, T=[300*(\frac{110}{100})^{23}]\\or, T=[300*(\frac{11}{10})^{23}]\\or, T=2686.29[/tex]

Since, number of cats cannot be a decimal value, therefore, Total number of stray cats in the city today are 2686, rounded off from 2686.29.

Compound Interest: Compound interest means that the interest increases exponentially, rather than increasing linearly over time, or in simpler words, it is a continuous interest on principal plus interest.

According to the given data the solution for the given equation 7 x⁻³=25 is 0.65421.

How do they solve logarithms?

To solve a logarithm, first determine the base, which really is "b" in the equation, the exponent, which is "y," and the exponentially expression, which is "x." Then, move the exponential expression around one side of the equation and transfer the exponent to the base by multiplying the base alone the number of times.

According to the given statement:

Given  7 x⁻³=25

Using multiple line and angle theorems, the values of each of the 14 angles are given.

Using the geometry theorems :

1.)

∠2 is a right angle = 90°

2.)

∠1 + ∠2 + ∠3 = 180° (sum of angle on a straight line)

90 + ∠1 + 54° = 180°

∠1 = (180 - 144) = 36°

(∠2 and ∠5) ; (∠3 and ∠6) ; (∠1 and ∠4) are vertically opposite ;

Hence,

∠4 = 36°

∠5 = 90°

∠6 = 54°

∠3 = ∠8 = 54° (corresponding angles)

∠9 + ∠8 = 180° (sum of angle on a straight line)

∠9 = (180 - 54) =126°

∠7 = ∠9 = 126° (vertically opposite angles)

∠8 = ∠10 = 54° (vertically opposite angles)

∠4 = ∠13 = 36° (corresponding angles )

∠12 + ∠13 = 180° (sum of angle on a straight line)

∠12 = (180 - 36) =126°

∠11 = ∠13 = 36° (vertically opposite angles)

∠12 = ∠14 = 126° (vertically opposite angles)

A rental car agency charges a flat fee of $131.00 plus $49.00 per day to rent a certain car. This will be

131 + 49d

Another agency charges a fee of $77.00 plus $58.00 per day to rent the same car. This will be

77 + 58d

Equate both equations

131 + 49d = 77 + 58d
