Step-by-step explanation:
Step 1, how many knives to buy?
The restaurant <u>already has 262 knives</u>. We can subtract this number from their needed 694 knives to find how many they still need:
knives.
Step 2, how many sets of knives?
The restaurant needs to buy 432 knives. We know the knives come in sets of 12, so <u>we can divide to find the # of packs she needs to buy</u>, determined by variable <em>s</em>.
Notice how the restaurant needs to buy a minimum of 694 knives, hence we use a greater or equal than symbol:

The correct question is:
Determine whether the given function is a solution to the given differential equation. y = cosx + x^8; d²y/dx² + y = x^8 + 56x^6
Step-by-step explanation:
Given the differential equation
d²y/dx² + y = x^8 + 56x^6.
Suppose y = cosx + x^8 is a solution, then differentiating y twice, and adding it to itself, must give the value on the right hand side of the differential equation.
Let us differentiate y twice
y = cosx + x^8
dy/dx = -sinx + 8x^7
d²y/dx² = -cosx + 56x^6
Now,
d²y/dx² + y = -cosx + 56x^6 + cosx + x^8
= 56x^6 + x^8
Therefore,
d²y/dx² + y = x^8 + 56x^6
Which shows that y = cosx + x^8 is a solution to the differential equation.
Answer:pretty sure its 10 degrees
Step-by-step explanation:
all tris add up to 180, and this one is a right angle so you know you have 90 deg, 80 degrees. 90+80=170; 180-170=10
The middle section is n(n+1)
The top row is n+2
The bottom row is 2n+1
So the rule for the total number of tiles will be the sum of the above rules...
s(n)=n(n+1)+n+2+2n+1
s(n)=n^2+n+n+2+2n+1
s(n)=n^2+4n+3
