Answer:

Equilateral triangle has 3 Reflection symmetry.

Step-by-step explanation:

Given  : Equilateral triangle.

To find : How many lines of a reflectional symmetry does a equilateral triangle have.

Solution : We have given a  equilateral triangle.

Equilateral triangle :triangle which has all three sides and angles are equal.

Reflection symmetry : If we reflect any shape of figure it gives same shape .

Therefore, Equilateral triangle has 3 Reflection symmetry.

Answer:

9m

Step-by-step explanation:

The surface area of a cube is given by

SA = 6s^2  where s is the side length

We know the surface area is 486 and the side length is z

486 = 6z^2

Divide each side by 6

486/6 = 6z^2/6

81 = z^2

Take the square root of each side

sqrt(81) = sqrt(z^2)

9 = z

Each side has a length of 9m

Answer:

A linear formula for S as a function of D is S=17D+1534

Step-by-step explanation:

We are supposed to find a linear formula for S as a function of D.

Equation of line : y = mx+c

We are given that At the surface, the speed of sound is 1534 meters per second.

c = 1534

We are given that for each increase in depth by 1 km, the speed increases by 17 m/s

So, Slope = m = 17

Substitute the values in equation

y=17x+1534

x denotes depth

y denotes speed

We are given that Use D for depth and S for the speed of sound

So, S=17D+1534

Hence a linear formula for S as a function of D is S=17D+1534
