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
Answer:
5/8 are spelled incorrectly
Step-by-step explanation:
There are 16 words
He spelled 6 correctly
That means he spelled 16-6 = 10 incorrectly
The fraction spelled incorrectly is wrong/total
10/16
Simplify by dividing the top and bottom by 2
5/8
After 1 year=x1.1
After 2 years=x1.1*1.1
………
After 5 years=x1.1*1.1*1.1*1.1*1.1=x1.61051
