How to you express area of each square as monomial

1 answer:

Ostrovityanka [42]4 years ago

The area of a rectangle (including squares) is defined as length times width or the equation:

A=l×w

However a square has the special property where length equals width which is represented by this equation:

l=w

So replace one of the variables with the other to get this new equation:

l×w=A
(w)×w=A
w^2=A

Often times for square the variable is represented as an s so:

s^2

A grasshopper jumps off a tree stump. The height, in feet, of the grasshopper above the ground after t seconds is modeled by the

Monica [59]

The height, in feet, of the grasshopper above the ground after t seconds is modeled by the function , which is

$h(t) =-t^2+\frac{4}{3}t+ \frac{1}{4}$

When the grasshopper land on the ground,

$h(t)=0$

that is,

$-t^2+\frac{4}{3}t+ \frac{1}{4}=0$

Multiplying whole equation by 12 to get rid of denominators 3 and 4

$-12t^2+16t +3=0$

$(3-2t)(6t+1)=0 \\ 3-2t=0 , 6t+1=0 \\ t= \frac{3}{2} , \frac{-1}{6}$

And time cant be negative, so the correct option is

$t = \frac{3}{2}=1.5 seconds$

Correct option is C .

How to classify a triangle by side and angle ?

s2008m [1.1K]

By angle:

We can classify a triangle 4 different ways when we're judging it by it's angle(s).

Acute: A triangle where all angles are less than 90 degrees.

Obtuse: A triangle where one angle is greater than 90 degrees.

Right: A triangle where one of the angles is exactly 90 degrees.

Equiangular: A triangle where all angles are the same (60 degrees.)

We can also classify a triangle by its sides:

Equilateral: (technically the same as an equiangular triangle, in order to have 3 equal sides you must have 3 equal angles as well.)

Isosceles: Two sides are the same length, where one is not.

Scalene: All three sides are different lengths.
