Answer:

The area is 88.39 cm

Step-by-step explanation:

Here, we want to find the area of the semicircle given that the diameter of the semi circle is 15 cm

We start by getting the radius

Mathematically r = D/2

= 15/2 = 7.5

Area of semicircle is area of circle/2

= (pi * r^2)/2

= (22/7 * 7.5^2)/2 = 88.39 cm

Changing the equation into slope form: y = mx + c, where m is the slope [gradient] and c is the y-intercept.

2x+3y=1470
3y = -2x+1470
y= - \frac{2}{3}x+ \frac{1470}{3}
y=- \frac{2}{3}x+490

The gradient is - \frac{2}{3} and y-intercept is at y=490

Graphing y=- \frac{2}{3}x+490 using slope-intercept method:
a) The slope is a negative slope. The line will go 'down hill'
b) The line must pass the point (0, 490)
c) The line will intercept the x-axis at y = 0
    0 = - \frac{2}{3}x+490
    \frac{2}{3}x = 490
    2x = 1470
    x = \frac{1470}{2}
    x = 735
    So, x-intercept is at (735, 0)

The graph of this function is shown below. The intercepts are labelled at:
y = 490
x = 735

-----------------------------------------------------------------------------------------------------------

Next month's profit equation

2x+3y=1593

Rewriting this into slope-equation form

3y = -2x+1593
y=- \frac{2}{3}+ \frac{1593}{3}
y= - \frac{2}{3}+531

The gradient, m, equals to - \frac{2}{3}
The y-intercept, c, equals to 531

The equation still has the same gradient with last month's profit equation but different y-intercept. 

-------------------------------------------------------------------------------------------------------------

A linear graph show points of (0, 300) and (450, 0)

We work out the slope: 
\frac{300-0}{0-450} = \frac{300}{-450}=- \frac{20}{30}  =- \frac{2}{3}


Y-intercept at x = 0, so it's at y = 300

Equation y = - \frac{2}{3}+300

Adição (+)

Positivo + Positivo = Positivo

Negativo + Negativo = Negativo

Positivo + Negativo ou Negativo + Positivo

• use o maior número e seu sinal, subtraia

Subtração (-)

Negativo - Positivo = Negativo

Positivo - Negativo = Positivo

Negativo - Negativo = Negativo + Positivo

• use o maior número e seu sinal, subtraia

Multiplicação (x)

Positivo x Positivo = Positivo

Negativo x Negativo = Positivo

Negativo x Positivo = Negativo

Positivo x Negativo = Negativo

• alterar os negativos duplos para um positivo

Divisão (÷)

Positivo ÷ Positivo = Positivo

Negativo ÷ Negativo = Positivo

Negativo ÷ Positivo = Negativo

Positivo ÷ Negativo = Negativo

• alterar os negativos duplos para um positivo
