Step-by-step explanation:
write equation in terms of x
y=(-6+3x)/12
from this equation u can see your gradient is 3/12 or 1/4
your perpendicular gradient is -1/m (m being the gradient of your main line)
so gradient of perpendicular= -4
since coordinate of main line is given, that point will also be on perpendicular.
so u have point and gradient so u can Calculate line equation
Y=MX+C
(-7)=(-4)(-1)+c
c=-11
y=-4x-11
^equation of perpendicular
we know that θ is in the III Quadrant, and let's recall that on the III Quadrant sine and cosine are both negative, and since tangent = sine/cosine, that means that tangent is positive. Let's also keep in mind that tan(π) = sin(π)/cos(π) = 0/-1 = 0.
well, the hypotenuse is just a radius unit, so is never negative, since we know sin(θ) = -(5/13), well, the negative number must be the 5, so is really (-5)/13.
Answer:
has an area 26,059,203 people that are not in the office
A.
5 * 2 = 10
8 * 2 = 16
10 cm by 16 cm is the new dimensions. Area = 160 sq cm. Perimeter = 52 cm.
B.
5 * 3 = 15
8 * 3 = 24
15 cm by 24 cm is the new dimensions. Area = 360 sq cm. Perimeter = 78 cm.
C.
The areas for the different sized photos both still maintain a ratio of 5:8 cm.
