Step-by-step explanation:
64,32,16,8,4. is a geometric sequence. this is a sequence where, to get from one term to the next, there is a number that you have to multiply it by. this is the same for all parts of the sequence.
Answer:
Center: (3,5)
Radius: 2
Step-by-step explanation:
x² + y² - 6x - 10y + 30 = 0
Put equation into center-radius form. First regroup terms:
(x²-6x) + (y²-10y) = -30
Complete the squares:
(x²-6x+3²) + (y²-10y+5²) = -30 + 3² + 5²
(x-3)² + (y-5)² = 4 = 2²
Center: (3,5)
Radius: 2
Answer:
the answer is 1
Step-by-step explanation:
Answer:
y- intercept = 22
Step-by-step explanation:
to find the y- intercept substitute x = 0 into f(x)
f(0) = (0 - 11)(0 - 2) = - 11 × - 2 = 22 → (0, 22 )
