The room is 5 inches long in the drawing.
Step-by-step explanation:
Given,
Scale drawing used by Kenneth;
1 inch = 4 feet
Ratio of scale = 1:4
Actual length of room = 20 feet
Let,
x be the length in drawing
Ratio of actual length = x:20
Using proportion
Scale ratio :: Actual ratio
Product of mean = Product of extreme
Dividing both sides by 4
The room is 5 inches long in the drawing.

Given :
A complex number z = 10 - 13i .
To Find :
Which quadrant will the complex number (10 - 13i) be found.
Solution :
Coefficient of real part of complex number, r = 10.
Coefficient of imaginary part of complex number, i = -13.
Since, the coefficient of imaginary part is -ve and real part is +ve .
Therefore, the complex number is in 4th quadrant.
Hence, this is the required solution.
Answer:
1
Step-by-step explanation:
Substitute 3 for x and 2 for y:
3^2 - 2(3)(2) + 2^2
= 9 - 12 + 4
= 1
Answer:
(-4, -2) is the answer
Step-by-step explanation:
is you move 7 units down from the zoo you will see ur also 2 units from the park and the coordinates would be (-4, -2)

Given the vector
v = 6i + 2√3j
The Magnitude of a vector:
![\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{ab}=\sqrt[n]{a}\sqrt[n]{b}](https://tex.z-dn.net/?f=%5Cmathrm%7BApply%5C%3Aradical%5C%3Arule%7D%3A%5Cquad%20%5Csqrt%5Bn%5D%7Bab%7D%3D%5Csqrt%5Bn%5D%7Ba%7D%5Csqrt%5Bn%5D%7Bb%7D)
The Direction of a vector:
tan Ф = y/x
y=2√3
x = 6
tan Ф = y/x
= 2√3 / 6
= √3 / 3
