Find all points having an x-coordinate of 5 whose distance from the point (2, 6) is 5

andre [41]

Answer:

The points are (5,2) and (5,10)

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$(2,6)\ and\ (5,y)\\d=5\ units$

substitute in the formula

$5=\sqrt{(y-6)^{2}+(5-2)^{2}}$

solve for y

$5=\sqrt{(y-6)^{2}+(3)^{2}}$

$5=\sqrt{(y-6)^{2}+9$

squared both sides

$25=(y-6)^{2}+9$

$(y-6)^{2}=25-9$

$(y-6)^{2}=16$

square root both sides

$(y-6)=\pm4$

$y=6\pm4$

so

$y=6+4=10$

$y=6-4=2$

therefore

The points are (5,2) and (5,10)

Given sin y = -4/5, where π < y < 3π/2, and cos x = 12/13, where 0 < x < π/2. Find the exact value of sin (x - y).

konstantin123 [22]

Answer:

Solution given:

sin y = -4/5

p/h=4/5

p=4

h=5

b=√{5²-4²)=3

cos y = b/h=-3/5

again

cos x=12/13

b/h=12/13

b=12

h=13

p=√(13²-12²)=5

sin x=p/h=5/13

now

sin[x-y]=sinxcosy-cosxsiny

=5/13×-3/5-(12/13×-4/5)=33/65 is your answer.
