Answer:

B

Step-by-step explanation:

So from the first graphs equation is

2x-y=-1

therefore if we made y the subject of the formula, the equation would be

2x+1=y , this is also the same as y=2x+1

from this, the equation is clearly in the form y=mx+c so we can get the gradient

The gradient of graph one would be 2

The perpendicular gradient would be the negative reciprocal of graph one's gradient which would be -1/2

Now we look at our options and see which one has the gradient as -1/2

In ΔOPQ, q = 110 inches, o = 970 inches and ∠P=167°. Find the area of ΔOPQ, to the nearest square inch.
ki77a [65]

Answer:

Area = 12004 square inches

Step-by-step explanation:

Given

q = 110

o = 970

\angle P =167

Required

The area of the triangle

To do this, we use:

Area = \frac{1}{2} * o * q * sin(P)

So, we have:

Area = \frac{1}{2} * 970 * 110 * sin(167^\circ)

Area = \frac{1}{2} * 970 * 110 * 0.2250

Area = 12003.75

Approximate

Area = 12004
