Answer:
slope of a line m : 0
Equation of line : y=- 9
Step-by-step explanation:
P1 : (X1 , Y1 ) (-3 , -9)
P2 : (X2 , Y2) (5 , -9)
Slope of line (m) is caculated as ,
m = ( y2-y1)/(x2 - x1)
m = (-9 - (-9))/(5 - (-3))
m = 0
equation of line : y = mx+b
using P1 (-3 , -9)
= > (-9) = (0)(-3) + b
= > -9 = b
hence b = -9
equation of Line is
y = -9
You would find the square root of 361.

Answer:
The actual length of the helicopter is <u>23 feet</u>.
Step-by-step explanation:
Given:
On a scale drawing, a helicopter is 2.3 feet long.
The scale on the drawing shows a ratio of 1 foot to 10 feet.
Now, to find the actual length of the helicopter.
Let the actual length of helicopter be
.
On scale drawing length of helicopter = 2.3 feet.
The scale on the drawing shows a ratio = 1:10.
Now, as ratios are given so by setting proportion we solve it:

<em>By cross multiplying we get:</em>
⇒ 
⇒ 
⇒ 
Therefore, the actual length of the helicopter is 23 feet.
Answer:

Step-by-step explanation:

Multiply.
