Yo mean sqrt 27 or √27

remember
√(xy)=(√x)(√y)

√27=(√9)(√3)=(3)(√3)=3√3

Travis is deciding how to study math tonight he is choosing between studying ofG patterns P or equations E he also is deciding w

expeople1 [14]

Answer:

GT, GV, PT, PV, ET, and EV.

Step-by-step explanation:

Given that

The number of topics Travis has to chose from are 3 topics(G, P, E).

The number of ways Travis can study each topic are 2 ways(T, V).

Essentially, the number of combinations Travis is expected to be able to chose from is given as

The number of combinations = The number of topics * The number of ways

The number of combinations = 3 * 2

The number of combinations = 6

Therefore, the total possible combinations has to be

GT, GV, PT, PV, ET, and EV

Suppose a circle with center (14, 9) passes through point (16, 12). Which equation represents the circle?

kumpel [21]

Answer:

The equation that represents the circle is $(x-14)^{2}$ + $(y-9)^{2}$ = 13

Step-by-step explanation:

Given the center of circle (14,9) passes through point (16,12)

We know that the equation of circle is

$(x-h)^{2}$ + $(y-k)^{2}$ = $r^{2}$

where (x,y) is any point on the circle, (h,k) is center of the circle and r is radius of circle.

From given data (x,y) is (16,12) and (h,k) is (14,9). Substituting these values in equation of circle, we get

$(16-14)^{2}$ + $(12-9)^{2}$ = $r^{2}$

$r^{2}$ = $2^{2}$ + $3^{2}$

$r^{2}$ = 13

Substituting the values of (h,K) and $r^{2}$ as (14,9) and 13 respectively in equation of circle, we get

$(x-14)^{2}$ + $(y-9)^{2}$ = 13

Hence the equation that represents the circle is $(x-14)^{2}$ + $(y-9)^{2}$ = 13

If point G is rotated 90 degrees counter clockwise around the origin, what is the resulting point?

Alex787 [66]

Answer: Point F

Step-by-step explanation:

the formula for rotation of 90 degrees counter-clockwise is (-y, x).

G=(-3,-2)

After 90 degrees counter-clockwise G is =(2,-3) which is equal to point F.
