Can someone help me with this question.

Mathematics
1 answer:
Flauer [41]3 years ago
5 0

Explanation:

angle BCA ≅ angle ECD . . . . . . vertical angles are congruent

∆BCA ≅ ∆ECD . . . . . . . . . . . . . . SAS congruence theorem

BA ≅ ED . . . . . . . . . . . . . . . . . . . .CPCTC

__

Based on the given congruences and the congruence of the vertical angles at C, we can invoke SAS congruence to show ∆BCA ≅ ∆ECD. Then the desired segments are congruent because corresponding parts of congruent triangles are congruent.

Determine and state the coordinates of the center and the length of the radius of the
zmey [24]

we can see that the center is (-3, 3) and the radius is 9 units.

<h3 /><h3>How to find the center and radius of the circle?</h3>

The general circle equation, for a circle with a center (a, b) and radius R is given by:

(x - a)^2 + (y - b)^2 = R^2

Here we have the equation:

x^2 + y^2 + 6x = 6y + 63

Let's complete squares:

x^2 + y^2 + 6x - 6y =  63

(x^2 + 6x) + (y^2 - 6y) = 63

(x^2 + 2*3x) + (y^2 - 2*3y) = 63

Now we can add and subtract 9, (two times) so we get:

(x^2 + 2*3x + 9) - 9 + (x^2 - 2*3x + 9) - 9 = 63

(x + 3)^2 + (y - 3)^2 = 63 + 9 + 9 = 81 = 9^2

(x + 3)^2 + (y - 3)^2 = 9^2

Comparing with the general circle equation, we can see that the center is (-3, 3) and the radius is 9 units.

Suppose the average yearly salary of an individual whose final degree is a​ master's is ​$45 thousand less than twice that of an
Lera25 [3.4K]

Answer:

<h2>$58500</h2>

Step-by-step explanation:

 let the degree holder earn  x

 then a masters degree holder earns= (2x-45,000)

the comnined amount of the two degree holders=   (2x-45,000)+x

2x-45000+x=117000

3x=117000+45000

3x=162000

x=162000/3

x=$54000

so bachelor'sdegree hold earns= $54000

a masters degree holder earns= (2(54000)-45,000)

a masters degree holder earns= (108000-45,000)

a masters degree holder earns=$63000

the average= (54000+63000)/2

the average= (117000)/2

the average=$58500

Now, as for the other part, the question is vague here. It does not specify whether "money supply" refers to the money in the government (therefore it would increase) or if it refers to the public (in which case it decreases). <span>it is decreased by $30,000.</span>
