Big/small=4/7
r1/r2=4/7 where r1, r2 are radius of a big and small circles respectively
r1/3=4/7
r1=12/7
circumference of a big circle is2πr1=2π*12/7=24π/7 cm
Change % = (77-70)/77 *100
= 100/11 = 9.1 % decrease
option C)
hope it helped
Answer:
vertex = (3, 4 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = - (x - 3)² + 4 ← is in vertex form
with (h, k ) = (3, 4 ) ← vertex
Answer:
E
Step-by-step explanation:
The line is negative and it was shifted down 5 units meaning it goes through -5,0. It needs to move up five so y=-4x-5+5= y=-4x
