On awall of dimension10.5m long and 8.5 m wide, a square shaped wall posture is stuck at the centre whose one side measures2.5m.
tangare [24]

Answer:

₹996

Step-by-step explanation:

Area painted = area of wall - area of wall posture

Area of a rectangle = length x breadth

= 10.5m x 8.5m = 89.25m^2

Area of a square

length x length

2.5m x 2.5m = 6.25m^2

Area painted =  89.25m^2 -  6.25m^2 = 83m^2

Total cost of area painted = 83m^2 x 12 = 996

The table shows the height of a plant as it grows. Which equation in point ­slope form gives the plant’s height at any time
vodka [1.7K]

Answer:

Option A is correct.

y-16=8(x-2) is the equation represent the point slope form gives the plant's height at any time.

Step-by-step explanation:

Point slope intercept form: For any two points (x_1, y_1) and  (x_2, y_2) then,

the general form

y-y_1=m(x-x_1) for linear equations;  where m is the slope given by:

m =\frac{y_2-y_1}{x_2-x_1}

Consider any two points from the table;

let A= (2 , 16) and B =(4, 32)

First calculate the slope of the line AB:

m =\frac{y_2-y_1}{x_2-x_1}=\frac{32-16}{4-2}=\frac{16}{2} = 8

Therefore, slope of the line m = 8

Then,

the equation of line is:

y-y_1=m(x-x_1)

Substitute the value of m=8 and (2, 16) above we get;

y-16=8(x-2)

Therefore, the equation in point slope form which gives the plant's height at any time is; y-16=8(x-2) , where x is the time(months) and y is the plant height (cm)

marusya05 [52]

Answer:

30,114.3%

Step-by-step explanation:

Use the percent increase formula:

((new value - initial value) / initial value) x 100

Plug in the values:

((211,500 - 700) / 700) x 100

(210,800 / 700) x 100

= 30,114.29

So, the percent increase is 30,114.3%
