Answer:
B
Step-by-step explanation:
260 because the tens position is the far right one before the decimal, and the number is above 5.
2x + 7y + 2 = 0
2(-1) + 7(-3) + 2 = 0
-2 - 21 + 2 = 0
-21 = 0
Consider this option:
1.the equation of the circle using its centre and point (0;-4) is:
x²+y²=4.
2. to substitute given point (23;2) into the equation of the circle:
23²+2²≠4
answer: this point does not belongs to the circle.
Answer:
ans is C. 63 ft.
Step-by-step explanation:
u, tree base n tree top form a right-angle triangle w/
an angle of 49deg
adjacent side = 55'
opposite side = tree height
using trig fn tan(angle)=opposite/adjacent
tan(49deg)=tree height/55'
tree height=55'*tan(49deg)
=63.27' rounding to 63 ft.
