What are the solutions of tye quadratic equation below 3x²-x=11

Step-by-step explanation:đáp án a

∆=b²-4ac= 1² - 4*3*(-11)=133

=>√∆=√133

X=(-b±√∆)/2a

X=(-(-1)±√133)/2*6

X=(1±√133)/6

part d

theresa talked her parents into getting sd cards for her phone and her brother’s phone. inserting an sd card into a phone gives it more storage. they both get 8-gigabyte sd cards. how many bits of storage come with each sd card? type your answer in both scientific and standard notation.

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)
