Complete the missing parts of the paragraph proof. Proof: We are given a ^ 2 + b ^ 2 = c ^ 2 triangle ABC and right triangle DEF constructed with legs a and band hypotenuse n. Since triangle DEF is a right triangle, we know that a ^ 2 + b ^ 2 = n ^ 2 * b * e because of the substitution c ^ 2 = n ^ 2 Using the square root property and the principle root, we can take the square root of both sides get c approx n. By triangles ABC and DEF are congruent . Since it is given that angle F is a right angle, is also a right angle by CPCTC. Therefore, triangle ABC is a right triangle by

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
