Step-by-step explanation:
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
Using the vertex of the equation, it is found that the correct option regarding the minimum number is given by:
C. n = 2(t - 2)² + 7.
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
Considering a standard equation, given by:
y = ax² + bx + c.
The vertex is given by:
.
If a is positive, the vertex is a minimum value.
In this problem, the equation is given by:
n = 2t² - 8t + 15.
The coefficients are: a = 2, b = -8, c = 15.
Hence:
.
The minimum is 2 hours after 10 a.m., hence 12 p.m, and the function is:
C. n = 2(t - 2)² + 7.

<span>f(x)= 2x²-4x
</span><span>g(x)= 5-2x
</span> f(x)-g(x) = 2x²-4x - ( 5-2x) = 2x² - 4x-5+2x= 2x² -2x-5
f(x)-g(x) = 2x² -2x-5
f(5)-g(5) = 2*5² -2*5-5=50-10-5 =35
f(5)-g(5) = 35
