find the area of equilateral triangle of side is 6cm​

Answer:

area = 6×3 = 18cm², ans

Step-by-step explanation:

see as it is equilateral all sides are equal so you can multiply one side by 6cm(as given value of one side) Or you can add all the sides like 6+6+6=18cm(as given in question)

Answer:

hhjjii to the other one is there a time

Answer:

An eye can focus the image of distant objects as well as nearby objects on its retina by changing its focal length. The contraction of the ciliary muscles decreases the focal length and relaxation of these ciliary muscles increases the focal length of the eye lens.

The equation of the tangent to the curve x ^ 2 = 4y at a point where x = 0 is​

Answer:

Given, x

2

=4y

Slope of tangent to the curve will be 4

dx

dy

=2x

⇒

dx

dy

=

2

x

So slope of normal will be −

dy

dx

=

x

−2

Let the point on the curve be (h,k)

So slope of normal will be

h

−2

Equation of normal is given by (y−k)=

h

−2

(x−h)

It is given that the normal passes through (1,2)

⇒(2−k)=

h

−2

(1−h).............(1)

Also, (h,k) lies on the curve so h

2

=4k

From (1) we have

4

h

3

=2h+2−2h=2

⇒h

3

=8

⇒h=2

k=

4

h

2

⇒k=1

So the equation will be

y−1=

2

−2

(x−2)

x+y=3

Answer:

y=0

Step-by-step explanation:

y = x²/4

=> dy/dx=x/2

=> slope of tangent at x=0 is 0/2 = 0

Also, at x = 0, y=0

Therefore, equation of the tangent is

y-0 = 0(x-0)

=> y=0
