To find a function (rule) for data you first seek to find its rate of change...

dy/dx=(11-5)/(14-8), (5-0)/(8-3)

dy/dx=1, 1  so this is a constant rate of change for the first derivative which means that it is just a line of the form:

y=mx+b  and we found above that m, dy/dx, the slope was just one so:

y=x+b, and using any point we can solve for b, the y-intercept, use (3,0)

0=3+b, so b=-3 and the "rule" is:

y=x-3  (the missing point was (7,4))

...

This next one you can just look at and see that it increases by one every time x increases by one so again you have a line of the form

y=x+b, using point (3,7) we solve for the y-intercept...

7=3+b, so b=4 and the rule is:

y=x+4  and the missing term was (12,16)

...

Uh, actually all of these tables have lines with a slope one... :P  so you really only need to find the y-intercepts and find the missing points...

...

y=x+b and using point (5,9)

9=5+b, b=4 and the line is

y=x+4, so the missing point is (14,18)

....

y=x+b and using point (14,16)

16=14+b, so b=2 so the line is:

y=x+2, and the missing term is (6,8)

Enter the coordinates of the vertices of r(180,0) and t(3,-2) (QRST) will give crown
Viktor [21]

Answer:

Step-by-step explanation:

From the graph attached,

Coordinates of the vertices are,

Q(1, 3), R(3, -3), S(0, -2) and T(-2, 1)

Following the rule of translation by 3 units to the right and 2 units down T_{(3, -2)}

(x, y) → (x+3, y-2)

Q(1, 3) → Q''(4, 1)

R(3, -3) → R"(6, -5)

S(0, -2) → S"(3, -4)

T(-2, 1) → T"(1, -1)

Following rule r_{(180,\text{O})} (rotation of a point by 180° about the origin) will give the image points,

(x, y) → (-x, -y)

Q"(4, 1) → Q'(-4, -1)

R"(6, -5) → R'(-6, 5)

S"(3, -4) → S'(-3, 4)

T"(1, -1) → T'(-1, 1)

Quadrant 2

Step-by-step explanation:

The top right corner is Quadrant 1, the top left corner is Quadrant 2, the bottom left corner is Quadrant 3, and the bottom right corner is Quadrant 4.

The point A is in the top left corner, meaning that it's in Quadrant 2.

Hope this helps!

Law of cosines.Anyone good in Trigonometry?​
marin [14]

Answer:

c=11.8\ units

Step-by-step explanation:

we know that

The formula of law of cosines is equal to

c^2=a^2+b^2-2(a)(b)cos(C)

where

a, b and c are sides. C is the angle opposite side c

In this problem we have

a=3\ units\\b=10\ units

C=120^o

substitute the given values

c^2=3^2+10^2-2(3)(10)cos(120^o)

c^2=109-(60)cos(120^o)

c^2=109-(60)(-0.5))

c^2=109+30

c^2=139

c=11.8\ units
