1 inch = 2.54 centimeters
10 inches = 2.54 x 10 = 25.4 centimeters
Therefore, t<span>o find the number of centimeters in 10 inches, multiply the number of inches given (10) by 2.54</span>
2 ways
1 calcluls
2. algebra
calculus, just take the deritivive and find wher it is 0
y=-0.2x+10
at x=50
sub 50 for x in original
y=250
algebra
for
y=a(x-h)²+k
(h,k) is vertex
k is maximum value
complete the square
y=(-0.1x²+10x)
y=-0.1(x²-100x)
take 1/2 of -100 and square it and add negative and positive inside
-100/2=-50, (-50)²=2500
y=-0.1(x²-100x+2500-2500)
factor perfect square
y=-0.1((x-50)²-2500)
exand
y=-0.1(x-50)²+250
vertex at (50,250)
producing 50 units yeilds a sale price of $250
max price is $250
Answer:
A and D and E
Step-by-step explanation:
Substitute the variable(in this case) <em>t</em> for 3, then use the order of operations to simplify(PEMDAS), which will give you 33 for both expressions. To see if two expressions are equivalent, you need to substitute the variable for an odd number AND an even number, so next, substitute the variable <em>t </em>for the number 6, which will give you 51 for both expressions. That means the expressions are equivalent
