Answer:
- even
- odd
Step-by-step explanation:
You know that x is an odd function, tan(x) is an odd function, and sec(x) is an even function.
The ratio of two odd functions will be an even function, so ...
x/tan(x) is even
The ratio of an odd and an even function will be odd, so ...
sec(x)/x is odd
Answer:
Cost of material is $245.31
Step-by-step explanation:
Let dimension of box,
<em>The length of this base is twice the width.</em>
<em>∴ </em>x = 2y
Volume of box = 10 m³
∴ xyz = 10
⇒ 2y²z = 10
⇒ y²z = 5
<em>Material for the base costs $15 per square meter.</em>
Total cost of base = 15xy
Total cost of base = 30y² [∵ x = 2y ]
<em>Material for the sides costs $9 per square meter.</em>
Total cost of side = 9(2xz+2zy)
Total cost of side = 18(xz+yz)
Total cost of material for container = 30y² + 18(xz+yz)
[From (i)]
Differentiate w.r.t y
For critical point , C'(y)=0
The minimum cost of container material at
Hence, the cheapest cost of material for container is $245.31
Answer:
7/8 cup/hr (Answer D)
Step-by-step explanation:
You're being asked to find the unit rate, the rate at which Enrique drank coffee each hour. Divide 2 3/16 cups by 2 1/2 hours:
2 3/16 cups 35 5
------------------- = ------- ÷ ------- = (35/16)*(2/5) = 70/80 cup/hr = 7/8 cup/hr
2 1/2 hours 16 2
11 and 19 are the two numbers
