The following graph describes function 1 and the equation below it describes function 2:
Tanya [424]
Function 1: 
f(x) = -x² + 8(x-15)f(x) = -x² <span>+ 8x - 120
Function 2:
</span>f(x) = -x² + 4x+1
Taking derivative will find the highest point of the parabola, since the slope of the parabola at its maximum is 0, and the derivative will allow us to find that.
Function 1 derivative: -2x + 8 ⇒ -2x + 8 = 0 ⇒ - 2x = -8 ⇒ x = -8/-2 = 4

Function 2 derivative:  -2x+4 ⇒ -2x + 4 = 0 ⇒ -2x = -4 ⇒ x = -4/-2 ⇒  x= 2
Function 1: f(x) = -x² <span>+ 8x - 120 ; x = 4
f(4) = -4</span>² + 8(4) - 120 = 16 + 32 - 120 = -72
<span>
Function 2: </span>f(x) = -x²<span> + 4x+1 ; x = 2
</span>f(2) = -2² + 4(2) + 1 = 4 + 8 + 1 = 13

Function 2 has the larger maximum.

HELP PLS I PUT THE PIC IN
agasfer [191]

Answer:

216 gallon

Step-by-step explanation:

We are given that

Milk in gallon  probability   week

200                   3/30            3

205                   4/30            4

210                   6/30           6

215                    5/30          5

220                    4/30          4

225                    3/30          3

230                     2/30          2

235                     2/30         2

240                     1/30         1

Total weeks=30

We have to find the average number of gallons of milk  consumed per week

The average number of gallons of milk  consumed per week

=Total number of gallons of milk/total weeks

Using the formula

The average number of gallons of milk  consumed per week

=\frac{200(3)+205(4)+210(6)+215(5)+220(4)+225(3)+230(2)+235(2)+240(1)}{30}

=\frac{6480}{30}

=216gallons/week

Hence, the average number of gallons of milk  consumed per week= 216 gallon

There are 6 pennies, 9 nickels, and 3 dimes in a box. Find the probability of...
valina [46]

Answer:

a) 4/17

b) 1/12

c) 3/34

d) 3/34

Step-by-step explanation:

a) The probability of choosing the first nickel is 9/(9 + 6 + 3) (because there are 9 nickels to choose from and a total of 9 + 6 + 3 = 18 coins to choose from) = 9/18 = 1/2. The probability of choosing the second nickel is 8/17 (because there's no replacement, we have 9 - 1 = 8 nickels remaining to choose from and 18 - 1 = 17 total coins). Multiply these together: (1/2) * (8/17) = 8/34 = 4/17

b) The probability of choosing a nickel is 9/18 (just like above) = 1/2. The probability of choosing a dime is 3/18 (because there are 3 dimes and since there IS replacement, we still have 18 total coins to choose from). Multiplying these, we get: (1/2) * (3/18) = 3/36 = 1/12

c) The probability of choosing a nickel is 9/18 = 1/2. The probability of choosing a dime after that is 3/17 (because there are 3 dimes to choose from, but since there's NO replacement, there are only 18 - 1 = 17 total coins). Multiplying these, we get: (1/2) * (3/17) = 3/34

d) The probability of choosing a penny is 6/18 (because there are 6 pennies) = 1/3. The probability of choosing a nickel next is 9/17 (because there is NO replacement, there are 18 - 1 = 17 total coins remaining). The probability of choosing a second nickel is 8/16 = 1/2 (because there are 17 - 1 = 16 total coins and 9 - 1 = 8 nickels left). Multiplying these, we get: (1/3) * (9/17) * (1/2) = 9/102 = 3/34

Hope this helps!
