A altura de uma cadeira de certa roda gigante varia segundo a função , em que t é o tempo, em minutos, que a roda está girando, e h é a altura, em metros, em relação ao solo. Qual é a altura dessa cadeira em relação ao solo 8 minutos após a roda começar a girar?

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
