You are given the vertex first so then you plug in the vertex in the vertex form for a quadratic equation which is y=a(x-h)^2+k. After you plug it in, you should have the equation y=a(x+2)^2-20. You are also given another point (0,-12) You then plug in the coordinates and solve for a. After you find your a you simply input the a,h and k values and leave the x and y alone.

A food manufacturer uses an extruder (a machine that makes bite size cookies)that yields revenue for the firm at a rate of $200
julsineya [31]

Answer:

$1300

Step-by-step explanation:

The extruder yields a revenue of $200per hour

Y denotes the number of breakdown per day.

The daily revenue generated is given as

R = 1600 - 50Y^2

We have an average of 2 breakdown per day

Lamda = 2

Represent lamda as β

E(Y) = β

E(Y(Y-1)) = β^2

E(Y^2) = E[Y(Y-1)] + E(Y)

= β^2 + β

E(R) = E(1600 - 50Y^2)

= 1600 - 50E(Y^2)

= 1600 - 50(β^2 +β)

Recall that β = lamda = 2

= 1600 - 50(2^2 + 2)

= 1600 - 50(4+2)

= 1600 - 50(6)

= 1600 - 300

= 1300

$1300

The expected daily revenue of the extruder is $1300

Please help this is the last question and determines wether I pass or not
givi [52]
Hopefully I’m not too late, but here’s how I solved it. Basically, replace F with 68. Subtract 32 from both sides so your equation becomes 9/5C=36. Divide both sides by 9/5 so C is left but itself (C=36/1.8). The answer should come out to 20. If you want to check my answer, plug 20 into the equation. Multiply 20x9/5 which equals 36. Add 36 and 32 together to get 68. Hope this helps

Rafael is putting money into a savings account. he starts with $650 in the savings account, and each week he adds $40.
mezya [45]

Answer:

Equation is S = 40w + 650

So S = 40(16) + 650

    S = 640 + 650

    S = $1,290

Step-by-step explanation:

this because each week (W) he adds $40 and the $650 is the initial amount in his savings account. So since 16 weeks went by, just multiply that by 40 and add 650 to that product.
