If a restaurant sells 6,000 meals in one month, at an average price of 17 per meal for the customer and an average cost of $4.60
mash [69]

Answer:

The percentage increase from the restaurant price to the restaurant cost = 269.56%

Step-by-step explanation:

An average price of per meal for the customer= $17

An average cost of per meal for the restaurant= $4.60

Difference in price = 17-4.60

Difference in price =  $12.4

So, the percentage increase from the restaurant price to the restaurant cost =\frac{12.4}{4.60} \times 100

The percentage increase from the restaurant price to the restaurant cost = 269.56%

A bacteria culture initially contains cells and grows at a rate proportional to its size. After an hour the population has incre
zheka24 [161]

Answer:

Step-by-step explanation:

given that a  bacteria culture initially contains cells and grows at a rate proportional to its size.

If P be the size then growth rate

P'=kP where k is constant of proportionality

separate the variables as

\frac{dP}{P} =kdt\\ln P =kt+C\\P = Ae^{kt}

If after 1 hour population is B (say)

B=Ae^{k} \\\\k = ln B - ln A

then k = ln B - ln A

Using this

P(t) = Ae^{(lnB-lnA)t}

b) P(e) = Ae^{(lnB-lnA)3}

c) Rate of growth = (ln B- ln A)Ae^{(lnB-lnA)3}

Unless you give B value, d cannot be solved

Solve a quadratic equation by factoring j2–30j=0
Lina20 [59]

Answer:

j = 0  or j = 30

Step-by-step explanation:

j² - 30j = 0

Factorise j out of both terms on the left side.

j (j-30) = 0

Apply zero product rule.

j = 0  or j-30 = 0

Find the value of j.

j = 0  or j = 30

What is the equation of the quadratic graph with a focus of (3, 4) and a directrix of y = 8?
aksik [14]

Answer:

The equation of the quadratic graph is f(x)= - (1/8) (x-3)^2 + 6 (second option)

Step-by-step explanation:

Focus: F=(3,4)=(xf, yf)→xf=3, yf=4

Directrix: y=8 (horizontal line), then the axis of the parabola is vertical, and the equation has the form:

f(x)=[1 / (4p)] (x-h)^2+k

where Vertex: V=(h,k)

The directix y=8 must intercept the axis of the parabola at the point (3,8), and the vertex is the midpoint between this point and the focus:

Vertex is the midpoint between (3,8) and (3,4):

h=(3+3)/2→h=6/2→h=3

k=(8+4)/2→k=12/2→k=6

Vertex: V=(h,k)→V=(3,6)

p=yf-k→p=4-6→p=-2

Replacing the values in the equation:

f(x)= [ 1 / (4(-2)) ] (x-3)^2 + 6

f(x)=[ 1 / (-8) ] (x-3)^2 +6

f(x)= - (1/8) (x-3)^2 + 6
