Find the length of GH!

Mathematics
2 answers:
Sati [7]3 years ago

Answer:

A

Step-by-step explanation:

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = G(6, 5) and (x₂, y₂ ) = H(8, 9)

GH = \sqrt{(8-6)^2+(9-5)^2}

      = \sqrt{2^2+4^2}

      = \sqrt{4+16}

      = \sqrt{20} ≈ 4.5 → A

Distance formula is square root of (x2-x1)^2 plus (y2-y1)^2
Which is the square root (6-8)^2 plus (5-9)^2
Which is 4.47
Which is approximately 4.5 hope this helps ;)

Find the x and y intercepts of the quadratic equation<br> f(x)=-x^2+4x-4
earnstyle [38]
<u>X - Intercept</u>
f(x) = -x² + 4x - 4
   0 = -x² + 4x - 4
   x = <u>-(4) +/- √((4)² - 4(-1)(-4))</u>
                         2(-1)
   x = <u>-4 +/- √(16 - 16)</u>
                    -2
   x = <u>-4 +/- √(0)
</u>               -2<u>
</u>   x = <u>-4 +/- 0
</u>              -2<u>
</u>   x = <u>-4 + 0</u>      x = <u>-4 - 0</u>  
            -2                 -2
   x = <u>-4</u>             x = <u>-4</u>
         -2                   -2
   x = 2               x = 2

The solution to the problem is {2, 2}, or {2}. The x - intercept of the problem is (2, 0).

<u>Y - Intercept</u>
f(x) = -x² + 4x - 4
f(x) = -(0)² + 4(0) - 4
f(x) = -(0) + 0 - 4
f(x) = -0 + 0 - 4
f(x) = 0 - 4
f(x) = -4

The y - intercept of the problem is (0, -4).

Which is an asymptote of the graph of the function y = cot ( x - 2pi / 3 )
vesna_86 [32]
\bf y=cot\left(x-\frac{2\pi }{3}  \right)\implies y=\cfrac{cos\left(x-\frac{2\pi }{3}  \right)}{sin\left(x-\frac{2\pi }{3}  \right)}

now, if the denominator turns to 0, the fraction becomes undefined, and you get a "vertical asymptote" when that happens, so let's check when is that

\bf sin\left(x-\frac{2\pi }{3}  \right)=0\implies sin^{-1}\left[ sin\left(x-\frac{2\pi }{3}  \right) \right]=sin^{-1}(0)&#10;\\\\\\&#10;x-\frac{2\pi }{3}=&#10;\begin{cases}&#10;0\\&#10;\pi &#10;\end{cases}\implies \measuredangle x=&#10;\begin{cases}&#10;\frac{2\pi }{3}\\&#10;\frac{5\pi }{3}&#10;\end{cases}

now, at those angles, the function is asymptotic, check the picture below

How much did it cost summer to to buy 2.6 pounds of granola at the old price
coldgirl [10]
It was $6.00 per pound.  So 2 pounds would be $12.  But there is still that .6 of a pound left.  If we know 1 pound costs $6, then we know 1/10th of a pound will cost $0.60.  So 6 x .60 = 3.60.  Add 12 and 3.60, and you get 15.60 for 2.6 pounds of granola at the old price.
