SOLVE THIS EXTREMELY IMPORTANT EQUATION

Answer:

Option B; EF = ( About ) 4.47 units, Perimeter of Δ EFG = ( About ) 12.94 units

Step-by-step explanation:

If we were to consider the height of this triangle EFG, it would be 4 units of length, supposedly splitting base GF into two ≅ parts, each 2 units of length. First let us name the point drawn to base GF ⇒ point H, so that the height of Δ EFG ⇒ EH. Now as EH splits GF into two ≅ parts, by Converse to Coincidence Theorem, Δ EFG ⇒ Isosceles Δ;

EH and FH are legs of a right triangle EFH, so that Pythagorean Theorem can be applied to solve for the length of EF and EG, knowing that as Δ EFG ⇒ Isosceles Δ, EF ≅ EG;

( EH )^2 + ( FH )^2 = ( EF )^2,

( 4 )^2 + ( 2 )^2 = ( EF )^2 ⇒ take square of 4 & 2,

16 + 4 = ( EF )^2 ⇒ combine like terms,

( EF )^2 = 20 ⇒ take square root on either side to solve for EF,

EF = √ 20 = ( About ) 4.47 units = EG,

Perimeter of Δ EFG = EF + GF + EG = 4.47 + 4 + 4.47 = ( About ) 12.94 units,

Solution; Option B

BRAINLIEST MATH okurttttt

Zepler [3.9K]

In the given question, $\sqrt{x-1}$ is shifted one unit to the right of $\sqrt{x}$

So, Option C is correct.

Step-by-step explanation:

The parent function is $\sqrt{x}$ and transformed function is $\sqrt{x-1}$

So, Parent Function: $\sqrt{x}$

Transformed Function: $\sqrt{x-1}$

If transformed function is of type: g(x) = f(x-h), then the graph is shifted to right h units.

So, In the given question, $\sqrt{x-1}$ is shifted one unit to the right of $\sqrt{x}$

So, Option C is correct.

Tamia's family traveled 5/8 of the distance to her grandfather's house on Saturday. They traveled 1/3 of the remaining distance

antoniya [11.8K]

Answer:

2/8

Step-by-step explanation:

Tamila traveled 5/8 of the distance to her grandmother house on Saturday

They traveled 1/3 of the remaining distance on Sunday

Therefore the total distance traveled to her grandmother's house on Sunday can be calculated as follows

5+1

= 6

8-6

= 2

2/8

Hence the distance travelled is 2/8
