Answer:
A.
Step-by-step explanation:
because as X approaches infinity, the negative sign will cause it to go opposite of X.
Answer:
A: venti has a better unit rate at .2275 cents per ounce
B: to get the unit rate you divide the cost by the number of ounces.
Step-by-step explanation:
tall = .2958 cents per ounce
grande = .2656 cents per ounce
venti = .2275 cents per ounce
The equation for surface area of a sphere is SA=4*pi*r^2
We can plug in what we know to solve for r
400=4*pi*r^2
100=pi*r^2 (divide out the 4)
100/pi=r^2 (divide out the pi)
√(100/pi)=r (square root of both sides)
r=5.6 rounded to the nearest tenth
Answer:
A = 169π/4
Step-by-step explanation:
From these two given points we find the length of the diameter of this circle, using the Pythagorean Theorem:
d^2 = (8 - 3)^2 + (13 - 1)^2, or
d^2 = 25 + 144 = 169
Thus, the diameter, d, of this circle is √169, or 13.
The radius is thus 13/2 units.
The area formula is A = πr^2. Here the area is
A = π(169/4), or A = 169π/4
