Answer:
36
Step-by-step explanation:
equilateral triangle has all sides So,
perimeter = a+b+c= 12+12+12=36
Answer:
V≈113.1cm³ radius = 3 cm
Step-by-step explanation:
Answer:
78.5 in ^2
Step-by-step explanation:
radius = 5
A = 25π
= 78.5
Step-by-step explanation:
y = ax^n + bx^(n-1) ... + z
(0, 1) tells us that the constant term z = 1.
because x = 0 eliminates all other terms. and as the sum is 1, that means z = 1.
for the other pairs I strongly suspect
(-1, 3) : 2×(-1)² + 1 = 2×1 + 1 = 3
(-2, 9) : 2×(-2)² + 1 = 2×4 + 1 = 9
so, the fitting equation is
y = 2x² + 1
