Juliette [100K]

Answer:

Leon is correct. (Option 1)

Step-by-step explanation:

Given that Leon verified that the side lengths 21, 28, 35 form a Pythagorean triple using this procedure.

Step 1: Find the greatest common factor of the given lengths: 7

Step 2: Divide the given lengths by the greatest common factor: 3, 4, 5

Step 3: Verify that the lengths found in step 2 form a Pythagorean triple.

we have to explain whether or not Leon is correct.

As, 3,4,5 forms a Pythagorean triplet i.e satisfies the Pythagoras theorem

$Hypotenuse^2=Base^2+Perpendicular^2$

⇒ $5^2=3^2+4^2$

Let a, b, c forms a Pythagorean triplet

$a^2+b^2=c^2$

Multiplied by 4 on both sides

⇒ $4a^2+4b^2=4c^2$

⇒ ${2a}^2+{2b}^2={2c}^2$

Hence, we say 4a, 4b and 4c also forms a Pythagorean triplet.

∴ multiplying every length of a Pythagorean triple by the same whole number results in a Pythagorean triple.

Hence, Leon is correct.

Let they meet after second car travels for x hours'
let v be the speed of second car and V be speed of first car.
Then time taken by first car=x+2
V(x+2)=vx (distance covered is same.)
$\frac{v}{V} = \frac{x+2}{x} 
subtract 1 from both sides
 \frac{v-V}{V} = \frac{2}{x} 
v-V= \frac{2V}{x}$

Can anyone figure this out and explain? Thanks

The deepest point of the lake is -922, so to get to the surface of the lake you would need to add 922 feet.

The deepest point of the lake is 11,542 feet above sea level.

To find the surface of the lake add 922 to 11,542.

11542 + 922 = 12,464 feet

dalvyx [7]

Answer:

"Vertical shift" is the type of transformation among the following choices given in the question if the parent function f(x) = (2x – 3)³ is transformed tog(x) = (-2x + 3)³. The correct option among all the options that are given in the question is the first option. I hope that the answer has come to your great help.
