The SAS congruence is basically:
S- side
A- angle
S - side

If two triangles have two congruent sides and share one angle (or have one angle in between), then it (the triangles) are considered congruent.

Find an equation of the sphere that passes through the point (7, 1, −3) and has center (5, 6, 5).

xz_007 [3.2K]

Answer:

The equation of the sphere that passes through the point (7,1,-3) and center at (5, 6, 5) is $(x-5)^{2}+(y-6)^{2}+(z-5)^{2} = 93$ .

Step-by-step explanation:

Any sphere centered at $(h,k,s)$ in an Euclidean space with a radius $r$ is represented by the following formula:

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

If $(x,y,z) = (7,1,-3)$ and $(h,k, s) = (5,6,5)$ , the radius of the sphere is obtained:

$(7-5)^{2}+(1-6)^{2}+(-3-5)^{2} = r^{2}$

$r^{2} = 93$

$r = \sqrt{93}$

The equation of the sphere that passes through the point (7,1,-3) and center at (5, 6, 5) is $(x-5)^{2}+(y-6)^{2}+(z-5)^{2} = 93$ .

Mark and Don are planning to sell each of their marble collections at a garage sale. If Don has 2 more than 5 times the number o

Mark and Don have 18 and 92 marbles respectively.

<h3>What is the solution of the equation?</h3>

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved.

Let the number of marbles Mark has be x.

According to the question,

Don has (5x+2) marbles.

Total number of marbles=110

Thus, the required equation is:

x+5x+2=110

6x=108

x=108/6

x=18

Mark has 18 marbles.

Don has (5*18+2)=92 marbles.
