in the diagram, AE is tangent to the circle at point a and secant DE intersects the circle at point C and D. the iines intersect

AlexFokin [52]

Recall the secant-tangent theorem, and you have
EA^2 = EC*CD
12^2 = 8*(x+10)
and now ED = EC+CD = 8+x+10

I suspect a typo somewhere in the murk above

Twenty-six students apply to serve as an usher at a school function. Eight of the those applying are freshmen, 7 are sophomores,

Gelneren [198K]

Answer:

d

Step-by-step explanation:

from usatestprep:

The situation is not an example of uniform probability because freshmen, sophomores, juniors, and seniors do not have equal probabilities of being selected.; Uniform probability → equal probability of being selected

Point B is the midpoint of point C and D. If CB is 14in, what is CD and BD?

stich3 [128]

Answer:

$BD = 14\ in$

$CD = 28\ in$

Step-by-step explanation:

Given

CB = 14in

B as midpoint

Required

Determine CD and BD

<em>Since B is the midpoint, then the two line segments (CB and BD), we have the following relationships:</em>

<em></em> $CB = BD$

$CD = CB + BD$

Reorder the first equation

$BD = CB$

Substitute 14 for CB

$BD = 14\ in$

Taking the second equation into consideration

$CD = CB + BD$

$CD = 14 + 14$

$CD = 28\ in$

Find the component form of the vector that represents the velocity of an airplane at the instant its wheels leave the ground, if

vekshin1

Answer:

The component form of the vector that represents the velocity of the airplane is $(74.1 i , \ 11.73j)\ mph$

Step-by-step explanation:

Given;

velocity of the airplane, v = 75 mph

direction of the plane, θ = 9°

The vertical component of the velocity is given by;

$V_y = vsin\theta\\\\V_y = (75)(sin \ 9^0)\\\\V_y = 11.73 \ mph$

The horizontal component of the velocity is given by;

$V_x = vcos \theta\\\\V_x = (75)(cos9^0)\\\\V_x = 74.1 \ mph$

Therefore, the component form of the vector that represents the velocity of the airplane is given as;

$(V_x , \ V_y) = (74.1 , \ 11.73)\ mph$
