Answer:

41 degrees

Step-by-step explanation:

step 1

<em>Find the measure of arc DGF</em>

we know that

The inscribed angle is half that of the arc comprising

so

m\angle E=\frac{1}{2}[arc\ DGF]

we have

m\angle E=123^o

substitute

123^o=\frac{1}{2}[arc\ DGF]

arc\ DGF=246^o

step 2

<em>Find the measure of arc EF</em>

we know that

arc\ DGF+arc\ DE+arc\ EF=360^o ----> by complete circle

substitute the given values

246^o+73^o+arc\ EF=360^o

319^o+arc\ EF=360^o

arc\ EF=360^o-319^o=41^o

Judging by the question I generated the equation y=75(1.09^x)
x is the amount of years. 
So the equation you should get for 10 years is y=75(1.09^10)
The answer you get should get is $177.55

Can you help me with these questions<br>​
dlinn [17]

Answer:

see below (I hope this helps!)

Step-by-step explanation:

41. √20 = √4 * 5 = √4 * √5 = 2√5

43. The sum of interior angles in a triangle is 180°, therefore, x = 180 - (75 + 64) = 41°.

45. 15 + 5(2x - 3) = 15 + 5(2x) + 5(-3) = 15 + 10x - 15 = 10x

47. Complementary angles have a sum of 90°, therefore, x = 90 - 48 = 42°.

What is the equation of the circle with center (1, -1) that passes through the point (5, 7)?
Inessa [10]

Answer:

Equation of the circle =

80 = ( x - 1)^2 + (y + 1)^2

Step-by-step explanation:

Center = (1 , -1)

Point = ( 5 , 7)

Eqn of a circle is

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

We are not given the radius of the circle, fortunately we are provided the information that the circle contains a point ( 5, 7), so we use the above information to find r

Using the center (1, -1)

h - 1

k - -1

r^2 = (x - 1)^2 + ( y - -1)^2

r^2 = (x - 1)^2 + (y + 1)^2

With the point ( 5,7)

x = 5

y = 7

r^2 = ( 5 - 1)^2 + ( 7 + 1)^2

= 4^2 + 8^2

= 16 + 64

= 80

r^2 = 80

r = square root of 80

r = 8.94

The r = 8.94 , which means the equation of the circle is

80 = (x - 1)^2 + ( y + 1)^2
