y=1/38*x^2
here h=0,k=0 ,a=1/38

so if we put values to find focus

Someone help me on this please!
swat32

Answer:

x = 15 cm


Step-by-step explanation:


All the ratio of corresponding sides should be equal


10 corresponds to x

16 corresponds to 24

12 corresponds to 18


<em>Finding the ratio of the known pairs:</em>

  • \frac{16}{24}=\frac{2}{3}
  • \frac{12}{18}=\frac{2}{3}

<em>Similarly 10 is to x should be 2 is to 3. Finding x:</em>

\frac{10}{x}=\frac{2}{3}\\10*3=2x\\30=2x\\x=\frac{30}{2}\\x=15


So x = 15.

Solve 3(x - 2) &lt; 18. A{x\x&lt;8)<br> B{x1x &gt; 8)<br> C[xlx&lt;-8}<br> D{xl x&gt;-8)
Evgen [1.6K]

Answer:

A. {x | x < 8}

Step-by-step explanation:

First, we divide both sides by 3.

3(x - 2)/3 < 18/3

Then simplify.

x - 2 < 6

Lastly, add 2 to both sides.

x - 2 + 2 < 6 + 2

<u>x < 8</u>
