23 × 32 is the prime factorization for which one of these choices?
forsale [732]

Hello.

Here's our explanation: First, you had to multiply line them up. 2*3=6, then 3*3=9. Bring down the zero, then multiply 2*2=4. And 3*2=6, which gives us equal to 640. Finally, add it up, 96+640=736. 736 is the final answer.

Hope this helps!

Thanks!

Have a great day!

The y-intercept of a parabola is 1, and its vertex is at (1,0). What function does the graph represent?
Nimfa-mama [501]

Answer:

A

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

Here (h, k) = (1, 0) , thus

y = a(x - 1)² + 0

To find a substitute the coordinates of the y- intercept (0, 1) into the equation

1 = a(- 1)² = a , thus

a = 1

y = (x - 1)² → A
