How would i calculate 1.9 minus 11/12?

Levart [38]

Answer:

59/ 60

Step-by-step explanation:

1.9 can be expressed as 19/10

Thus, our equation becomes

19/10 -11/12.

This becomes (228 -110) / 120

= 118 / 120

Simplify by 2 to get

59/60

Completing the square:

vichka [17]

Answer:

Step-by-step explanation:

Key to this method is remembering that

$(a+b)^2 = a^2 + 2ab + b^2$

So, if you divide the coefficient of x by 2 and square it, that will complete the square. With that in mind, things are easy.

6/2 = 3, so add $3^2 = 9$

$x^2+6x+9 = (x+3)^2$

So, c=9

Similarly, for the other two,

$c = (\frac{-34}{2} )^2 = (-17)^2 = 289$

You don't really have to worry about the sign, since squaring will always make it positive

$(\frac{25}{13}) ^2 = \frac{625}{169}$

Answer:

2π

Step-by-step explanation:

Period is the time it takes for the wave to reach one full cycle, which is the distance between the adjacent crests. The first crest is at 0 and the second crest is at 2π. Therefore, it takes 2π seconds to complete a full cycle. Hope this helps!

What is the equation of the line that passes through the points (-2, 1) and (6, 3)?

earnstyle [38]

Answer:

y = $\frac{1}{4}$ x + $\frac{3}{2}$

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 2, 1 ) and (x₂, y₂ ) = (6, 3 )

m = $\frac{3-1}{6-(-2)}$ = $\frac{2}{6+2}$ = $\frac{2}{8}$ = $\frac{1}{4}$ , then

y = $\frac{1}{4}$ x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (6, 3 ) , then

3 = $\frac{3}{2}$ + c ⇒ c = 3 - $\frac{3}{2}$ = $\frac{3}{2}$

y = $\frac{1}{4}$ x + $\frac{3}{2}$ ← equation of line
