Answer:
Hey there!
They are congruent by AAS, where two angles and one side is congruent.
Hope this helps :)
There is no graph doe ...
Answer:
(-2,-5), (0,-4), (3,5) (1,1)
Solution:
Only (0,-4) is on the line
(-2,-5), (1,1), and (3,5) is in the orange
(5,5) Isn't right because it's not on the line nor in the orange
Heyy merry christmas !
area of a triangle = base * height : 2
4 * 5 = 20 : 2 = 10
10 * 12triangles = 120cm^3
This problem deals the rate of change.
For the formula of the area of a circle, we differentiate both sides with respect to time t.
(A = πr^2) d/dt
dA/dt = 2πr (dr/dt)
Since we don't know yet the radius r, the area of a circle is given.
A = πr^2
r^2 = A/π = 4π/π
r^2 = 4
r = 2 cm
Therefore, the rate of the radius is
dA/dt = 2πr (dr/dt)
dr/dt = (dA/dt)/(2πr)
dr/dt = π/(2π*2)
dr/dt = 0.25 cm/min
Hope this helps.
