A point (x,y) in the xy-plane whose coordinates satisfy xy<0 lies in quadrant(s) ____ or ____ .

lubasha [3.4K]

The possible ordered pairs whose product will be negative (less than zero) are,

$(x,-y) \: or \: (-x,y)$

That is all these products will give us,

$- xy$

$-xy< 0$

The point must be in the second quadrant where x is negative and y is positive.

Or in the fourth quadrant, where y is negative and x is positive.

2. Given < MCP = 65°, find the measurement of arc MP , arc MRP and < MRP.

iren2701 [21]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

We know that the Angle subtended by an arc on centre of the circle is double as that of Angle subtended by the same arc on the circumference (boundary) of the circle

So,

$\sf \angle MCP = 2\angle MRP$

$\sf65 \degree = 2 \angle MRP$

$\sf\angle MRP = 65 \degree \div 2$

$\sf\angle MRP = 32.5 \degree$

Are all sides of the right angle have sides that are parallel

nydimaria [60]

-- The two sides of a right angle intersect and make the angle.
So do the sides of any other angle. So they can't be parallel.

-- No two sides of a right triangle ... or any other triangle ...can be parallel.

Derek owns a landscape business. He charges a fixed fee of $30 plus $1 per 1,000 square feet of lawn mowed. Derek's earnings (in

luda_lava [24]

From the given problem statement alone, we can say that the equation relating the area of the lawn mowed and the earnings has a linear relationship. That is because there is a constant increase in the earnings per area which is $1 per 1000 square feet.

Therefore the equation must be in the form of:

y = m x + b

where,

y = is the total earnings

m = is the fee per area = 1 / 1000

x = is the area of the lawn

b = is the fixed fee = 30

Therefore the equation becomes:

y = 0.001 x + 30

Rewriting this in terms for x since we are to find the area:

x = (y – 30) 1000

when y = 204

x = (204 – 30) 1000 = 174,000 square feet

when y = 344

x = (344 – 30) 1000 = 314,000 square feet

when y = 450

x = (450 – 30) 1000 = 420,000 square feet

when y = 482

x = (482 – 30) 1000 = 452,000 square feet

when y = 504

x = (504 – 30) 1000 = 474,000 square feet
