Exercise 10.3 1. Three ships P, Q and R are sailing such
that ship P is 2 km on a bearing of 040°
from Q. Ship R is 4 km on a bearing of
190° from Q. Calculate the area of the
triangle formed by the three ships.
A cat is placed in a triangular cage which
measures 2.5 m by 2.5 m by 3 m.
Calculate the area of the floor of the cage.
Three points: X, Y and Z, are marked on​

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

step-by-step explanation:

copy and paste, put it in google

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
