Modular arithmetic<br> Pls a little explaine it
fredd [130]

Step-by-step explanation:

(72)¹⁴³ ≡ x (mod 7)

Since 72 ≡ 2 (mod 7),

72³ ≡ 2³ (mod 7) ≡ 1 (mod 7).

Therefore (72)¹⁴³ = (72³)⁴⁷ * (72²)

≡ 1⁴⁷ * 4 (mod 7) ≡ 4 (mod 7).

The answer is A.

How can you write a fraction equivalent to 60/80 and with a denominator that is less than 80?
storchak [24]

Step-by-step explanation: To write 60/80 that has a denominator less than 80, we can write reduce this fraction.

Notice that 60/80 can be reduced because 60 and 80 have a greatest common factor of 20. So we divide both 60 and 80 by 20 to get 3/4. Now, this is an equivalent fraction that has a denominator that's less than 80. Image is provided below.

Can someone please help me with this math problem:)
Dennis_Churaev [7]

Answer:

x = 20

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{x}{12} = \frac{15}{9} ( cross- multiply )

9x = 180 ( divide both sides by 9 )

x = 20

What is the Vertex y=2x^2+6
inessss [21]
Compare this function to y=ax^2 + bx + c.  You can readily see that a=2, b=0 and c=6.

The x-coord. of the vertex is at x = -b / (2a).  Subbing the given values for a and b, we get 

x = -(0) / (2(2) = 0.  At x = 0, y = 6, so the vertex of this parabola is (0,6).  It opens upward.
