Answer:

The area of the small square is 1 cm^2

Step-by-step explanation:

The large square consist in four identical rectangles and one small square.

Then the area of the small square will be equal to the difference between the area of the large square and the areas of the rectangles.

Because we have 4 equal rectangles, if R is the area of one rectangle, and S is the area of the large square, the area of the small square will be:

area = S - 4*R

We know that the area of the large square is 49 cm^2

Then:

S = 49cm^2

Remember that the area of a square of side length K is:

A = K^2

Then the side length of the large square is:

K^2 = 49 cm^2

K = √(49 cm^2) = 7cm

And we know that the diagonal of one rectangle is 5cm.

Remember that for a rectangle of length L and width W, the diagonal is:

D = √(L^2 + W^2)

Then:

D = √(L^2 + W^2) = 5cm

And for how we construct this figure, we must have that the length of the rectangle plus the width of the rectangle is equal to the side length of the large square, then:

L + W = 7cm

L = (7cm - W)

Replacing this in the diagonal equation, we get:

√((7cm - W)^2 + W^2) = 5cm

(7cm - W)^2 + W^2 = (5cm)^2 = 25cm^2

49cm^2 - 14cm*W + W^2 + W^2 = 25cm^2

2*W^2 - 14cm*W + 49cm^2 = 25cm^2

2*W^2 - 14cm*W + 49cm^2 - 25cm^2 = 0

2*W^2 - 14cm*W + 24cm^2 = 0

We can solve this for W using the Bhaskara's formula, the solutions are:

W = [tex]\frac{-(-14)(+/-)\sqrt{14^{2}-4(2)(24) } }{2(2)}[/tex]

Then we have two solutions, and we only need one (because the length will have the other value)

We can take:

W = (14 cm + 2cm)/4  = 4cm

Then using the equation:

L + W = 7cm

L + 4cm = 7cm

L = 7cm - 4cm = 3cm

L = 3cm

Now remember that the area of one rectangle of length L and width W is:

R = L*W

Then the area of one of these rectangles is:

R = 4cm*3cm = 12cm^2

Now we can compute the area of the small square:

area = S - 4*R = 49cm^2 - 4*12cm^2 = 1cm^2

The area of the small square is 1 cm^2

The cash price for a car was £7460. Mr Roberts bought the car on the
following hire purchase terms: A deposit of 20% of the cash price and 36 monthly payments of £191.60. Calculate the total amount Mr Roberts paid.

Answers

To calculate the initial deposit of 20% you’ll need to do 7460*0.20 which is 1492.

The for the total of the 36 months you’ll do 191.60*36 which is 6897.60.

Then to get the total amount Mr. Roberts paid you’ll add the two totals we have 6897.60+1492 which would give the total amount paid of £8389.60.

Answers

The range of function (f + g)(x) is (-9, ∞) option (D) is correct the linear function g(x) is g(x) = -3x - 5

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = x² + 3x - 4

The domain of the f(x) is all real numbers

The range of the g(x) is [-6.25, ∞)

g(x) is shown in the table:

x      –6     –3     –1       4

g(x)    13      4     –2    –17

The linear function g(x) is:

[tex]\rm g(x) = \ -13=\dfrac{\left(4-13\right)}{-3+6}\left(x+6\right)[/tex]

g(x) = -3x - 5

(f + g)(x) = f(x) + g(x)

= x² + 3x - 4 - 3x - 5

(f + g)(x) = x² - 9

The domain of the function is all real numbers.

The range of the function (-9, ∞)

Thus, the range of function (f + g)(x) is (-9, ∞) option (D) is correct the linear function g(x) is g(x) = -3x - 5

Write a linear equation that passes through the points (-3, 3) and (9, -13) in standard form:

Answers

Answer:

  4x +3y = -3

Step-by-step explanation:

The standard form equation can be written from ...

  (y2 -y1)x -(x2 -x1)y = (y2 -y1)x1 -(x2 -x1)y1

  (-13 -3)x -(9 -(-3))y = (-16)(-3) -(12)(3)

  -16x -12y = 12

The standard form has a positive leading coefficient, and all terms mutually prime. We can get that by dividing the equation by -4:

  4x +3y = -3

_____

Additional comment

The form we used above for the equation of the line essentially comes from the fact that the slope of a line is the same everywhere:

  (y2 -y1)/(x2 -x1) = (y -y1)/(x -x1)

Multiplying by the product of denominators and separating variable terms from constant terms gives the form used above.

Write the equation of the line that is perpendicular to 3x+2y=8 and goes through the point (-5,2)

Answers

Answer:

[tex]\displaystyle y=\frac{2}{3}(x+5)+2[/tex]

Step-by-step explanation:

We need to find the equation of the line perpendicular to the line 3x+2y=8 and passes through (-5,2).

The given line can be expressed as:

[tex]\displaystyle y=-\frac{3}{2}x+4[/tex]

We can see the slope of this line is m1=-3/2.

The slopes of two perpendicular lines, say m1 and m2, meet the condition:

[tex]m_1.m_2=-1[/tex]

Solving for m2:

[tex]\displaystyle m_2=-\frac{1}{m_1}[/tex]

[tex]\displaystyle m_2=-\frac{1}{-\frac{3}{2}}[/tex]

[tex]\displaystyle m_2=\frac{2}{3}[/tex]

Now we know the slope of the new line, we use the slope-point form of the line:

[tex]y=m(x-h)+k[/tex]

Where m is the slope and (h,k) is the point. Using the provided point (-5,2):

[tex]\boxed{\displaystyle y=\frac{2}{3}(x+5)+2}[/tex]
