It is 2/3 of whole collection
then it is 3/5 of the 2/3
therefore she heard 3/5 of music in 2/3 of her collection
=3/5×2/5
=6/25
Answer:
Minimum Unit Cost = $14,362
Step-by-step explanation:
The standard form of a quadratic is given by:
ax^2 + bx + c
So for our function, we can say,
a = 0.6
b = -108
c = 19,222
We can find the vertex (x-coordinate where minimum value occurs) by the formula -b/2a
So,
-(-108)/2(0.6) = 108/1.2 = 90
Plugging this value into original function would give us the minimum (unit cost):
By definition we have the meaning of FOIL is given by:
F: First
O: Outer
I: Inner
L: Last
We have then the following product:
Applying the FOIL method we have that the products are given by:
Answer:
the answer choice showing the FOIL method products is:
B. (X) (4x) + (2) (x) + (- 3) (4x) + (- 3) (2)
Answer:
z = 156
Step-by-step explanation:
y² = 65²-25² = 4225 - 625 = 3600
(x+25)²-65² = z²
x²+50x+625-4225 = z²
x²+50x-3600 = z² ....(1)
x²+60² = z²
x²+3600 = z² ....(2)
(1)-(2): 50x - 7200 = 0
50x = 7200
x = 144
check: x² + y² = z² 144² + 60² = 24336 = z² z = 156
(25+144)²-65² = z² = 28561 - 4225 = 24336 z = 156
