Answer:
a
Step-by-step explanation:
this triangles are similar because 41+30+109 equals to 180
It’s 4x - 4y because to find the commute you add the two terms making 4x - 4y
Answer:
2x -6
Step-by-step explanation:
2x is slope
-6 is y intercept
The function passes though -6
a slope of 2 means the function goes up 2 and over 1 unit for every 1 x unit
Answer:
Q1: 48ft
Q2: 14.6
Step-by-step explanation:
Question 1:
Since the two triangles are similar (Angle - Side - Angle):
30/x = 50/80
x= 30(80/50)
=48
Question 2:
sin(55deg) = 12/x
12/sin(55) = x
x=14.6 (3 s.f.)
We have that the coordinates given are for a sphere.
As we look for a circle parallel to the xy plane, then our xy coordinates are:
(x, y) = (4, 2)
The standard equation of the circle is:
(x - h) ^ 2 + (y - k) ^ 2 = r ^ 2
where h and k are the x and y coordinates of the center of the circle and r is the radius.
We have then:
h = 4
k = 2
r = 3
The equation of the circumference is:
(x - 4) ^ 2 + (y - 2) ^ 2 = 9
answer
(x - 4) ^ 2 + (y - 2) ^ 2 = 9
