Answer:
Do the Pythagorean theorem
Step-by-step explanation:
4 squared plus 2.9 squared = C squared
Answer:
Step-by-step explanation:
The above is a right angled triangle
So you take the longest side
9.4^2 - 6.8^2
88.36- 46.24
sqrt of 42.12
6.4899
To the nearest tenth of a degree = 6.56.5ft
Answer:
Y = 43
Step-by-step explanation:
7^2 - y = 6
49 - y = 6
subtract 49
-y = -43
divide by -1
y = 43
Answer:C
Step-by-step explanation:
The standard equation of a circle is expressed as
(x - h)^2 + (y - k)^2 = r^2
where
h is the x coordinate of the center of the circle
k is the y coordinate of the center of the circle
r is the radius of the circle(the distance from the center of the circle to the circumference
From the graph,
h = - 1
y = 4
r = 5
By substituting these values into the equation, we have
(x - - 1)^2 + (y - 4)^2 = 5^2
(x + 1)^2 + (y - 4)^2 = 25
Thus, the equation of the circle is
(x + 1)^2 + (y - 4)^2 = 25
