II 24x2 =52<br>in What base at the<br>number?​
amm1812

Answer: WE are multiplying in base 6

Step-by-step explanation:

24 x 2 = 52 can only be in base 6

because    2¹  4            2 x 4 = 8/6 = 1 rem 2.                        

             <u> x        2₆   </u>         2 x 2 + 1= 5

              <u> </u><u> 5      2          </u>

From the above , we can see theta 24 x 2 = 52 can only  be in base 6.

Because only 2 x 4 = 12 can be possible in base 6.

Counting in base 6  gives us that after 5, the next number is 10. Just like counting in the common base 10, which after 9 we get 1 0

in Base 10--- 1, 2,3, 4,5, 6,7,8,9,10

in Base 6---  1, 2, 3,4,5,10,11,12, 13,14  and so o

Angle (&lt;) E and &lt;F are vertical angles. If m&lt;E = 17x+1 and m&lt;F =20x-14, find m&lt;F.
ELEN [110]

The vertical angles theorem states that vertical angles are congruent to each other. Since angles E and F are vertical angles, this means you can make them equal to each other in an equation.

m∠E = m∠F

17x + 1 = 20x - 14

Subtract 20x from both sides.

-3x + 1 = -14

Subtract 1 from both sides.

-3x = -15

Divide both sides by -3.

x = 5

Substitute 5 for x in m∠F (20x - 14).

20(5) - 14 = 86

m∠F = 86°

The function f(x) = x2 + 10x - 3 writers in vertex form is f(x) = (x + 5)2 - 28. What are the coordinates of the vertex?
andrey2020 [161]

General formula of the parabola in vertex form is

f(x) =(x-h)² +k, where (h,k) is a vertex of the parabola.

f(x) = (x + 5)²- 28

h= -5, k = -28,

so (-5, -28) is a vertex of the given parabola.

Answer is A.
