Answer:
The answer is 5 people
Step-by-step explanation:
This is because 30/6 equals 5
Answer:
Step-by-step explanation:
If the length of a bridge on a map is 1 cm,then the actual length = 40,000
If the length of a bridge on a map is 1.5 cm,then the actual length= 1.5 * 40000
= 60000.0 = 60,000 m
Answer: The answer is -2
Step-by-step explanation:
To make this easier, first draw or imagine a vertical line at x=2
Find where the vertical line and the graph intersects.
Draw or imagine that point of intersection.
Now, draw or imagine a horizontal line that goes through the point of intersection.
That horizontal line tells us the the value of the function by passing through that mark that says "-2"
The function's value at x=2 is -2.

Answer:
Take a line segment AB = 2 units (consider 1 unit = 2 cm) on x-axis.
Draw a perpendicular on B and construct a line BC = 1 unit length.
Join AC which will be √5 (Pythagoras theorem). Take A as center, and AC as radius draw an which cuts the x-axis at point E.
The line segment AC represents √5 unit
THe problem is basically telling us: ![P=kV^2](https://tex.z-dn.net/?f=%20P%3DkV%5E2%20)
where P is the power disappated and V^2 is our voltage squared.
![\frac{1}{16}=k*14^2\implies\\ \frac{1}{16*196}=k \implies \\ \frac{1}{3136}=k](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B16%7D%3Dk%2A14%5E2%5Cimplies%5C%5C%20%5Cfrac%7B1%7D%7B16%2A196%7D%3Dk%20%5Cimplies%20%5C%5C%20%5Cfrac%7B1%7D%7B3136%7D%3Dk%20)
So, for the second example to find the power we simply have to plug k and our voltage back in, so:![P=\frac{14^2*3^2}{14^2*6} \implies \\ P=\frac{9}{6}= \frac{3}{2}](https://tex.z-dn.net/?f=%20P%3D%5Cfrac%7B14%5E2%2A3%5E2%7D%7B14%5E2%2A6%7D%20%5Cimplies%20%5C%5C%20P%3D%5Cfrac%7B9%7D%7B6%7D%3D%20%5Cfrac%7B3%7D%7B2%7D%20)
