Answer:
Step-by-step explanation:
A shopper paid $2.52 for 4.5 pounds of potatoes. This means that the unit price for each potato would be
2.52/4.5 = 0.55556
Approximately $0.6 per pound.
The shopper paid $7.75 for 2.5 pounds of broccoli. This means that the unit price for each broccoli would be
7.75/2.5 = $3.1 per pound.
The shopper paid $2.45 for 2.5 pounds of pears. This means that the unit price for each pear would be
2.45/2.5 = $0.98 per pound
Difference of two squares is of the form (a + b)(a - b) or vice-versa. Here, a = -5x and b = 3.
(-5x - 3)(-5x + 3)
Answer: 3
The answer is 3.50
Because 15-7 equal 8,6 times 0.75 equal 4.50, and 8-4.5 equal 3.50
Answer:
Step-by-step explanation:
The foci are horizontally aligned.
horizontal ellipse:
(x-h)²/a² + (y-k)²/b² = 1
center (h,k)
vertices (h±a,k)
length of minor axis = 2b
foci (h±c,k), c² = a²-b²
Apply your data and solve for h, k, a, and b.
foci (±3√19, 6)
h = 0
k = 6
Length of minor axis = 2b = 10
b = 5
foci (h±3√19, 6)
c = 3√19
c³ = a² - b²
171 = a² - 25
a² = 196
x²/196 + (y-6)²/25 = 1
