Y = a(x - h)² + k • (h, k) is the vertex • x = h is line of symmetry so y = ax² - 2x - 3 y/a = x² - 2/ax - 3/a y/a + 3/a = x² - 2/ax y/a + 4/a= x² - 2/ax + (-1/a)² ← completing the square y/a + 4/a= (x - 1/a)² y/a = (x - 1/a)² - 4/a y = a(x - 1/a)² - 4 so since you've been given h = 1 then 1/a = 1 and so a = 1
I'm guessing the question is "how far does he have to walk to the store from where he is"
if he is walking home, then hmm
distance from store to school=1.8/2 since it is halfway, so 0.9 miles
he has walked 0.36 miles
so he needs to walk 0.90-0.36=0.54 miles
he needs to talk 0.54 miles to get to the store
A. The scientific notation for 50,000,000 is 5 x 10^7 (to the 7th power)
B. After squaring 50,000,000 you'll get <span>2500000000000000. In </span>scientific notation, this is 2.5 x 10^15 (to the 15th power).
C. I think what it's asking is how I solved part B... this could be wrong, double check it. I solved it by multiplying 50,000,000 x 50,000,000 and then converting the product into scientific notation.
