Addison pintó su habitación. Tenía 50 metros cuadrados por pintar, y pintó a una tasa constante. Después de pintar 2

horas, le faltaban 35 metros cuadrados.

A(t) = -7.5t +50

Step-by-step explanation:

The computation is shown below:

Here we use the two point form i.e. presented below

(y - y_1) = (y_2 - y_1) ÷ (x_2 - x_1)

where,

Y = painted area

x = elapsed time

x_1 = 0

y_1 = 50

x_2 = 2

y_2 = 35

Now place the values to the above formula

So,

The area to be painted should be

A(t) = -7.5t +50

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
