A has coordinates (-2,-5) what is A' after a Dilation with a scale factor of N = -3.

Mathematics
1 answer:
melamori03 [73]3 years ago
7 0

Answer:

A' = (6, 15)

Step-by-step explanation:

We consider the center point of dilation to be the origin (0,0)

so  point A(-2, -5)  to A'  by scale factor N = -3 means

A' = (-2*(-3),  -5*(-3)) = (6, 15)

A study on how circus ticket pricing influences ticket sales shows that there is an average increase of 4 people for every $3 de
____ [38]
Let the price of a ticket be originally T dollars, and the number of clients be N.

let the price decrease by x  3-dollars.

"there is an average increase of 4 people for every $3 decrease on the price of the ticket."

means:

if the price is decreased by 1-3$:
 then N become N+4, and T becomes T-3    


if the price is decreased by 2-3$:
 then N become N+4+4=N+2*4, and T becomes T-3-3=T-2*3    

 So if the price is decrease by x-3 dollars:

N  becomes N+4x, and T becomes T-3x


"A circus owner sells an average of 340 tickets when the price of a ticket is $75."

In this case N=340, and T=75$

If the owner does not change the price ticket, x=0, the revenue is 340*75,

If the owner decreases the price of the tickets by x-3$, then the revenue will be 
(N+4x)(T-3x)=(340+4x)(75-3x) dollars,

If R is the function of the revenue depending on x, then 

R(x)=(340+4x)(75-3x) dollars

 
Answer: R(x)=(340+4x)(75-3x) dollars

for a different punch recipe, the equation,s=4c represents the number of cups of seltzer,s, that you need for,c, cups of cranber
asambeis [7]

Answer:

4

Step-by-step explanation:

If two variables are proportional then

y\propto x

y=kx    ...(i)

where, k is constant of proportionality.

The given equation is

s=4c       ...(ii)

where,

s = number of cups of seltzer.

c = cups of cranberry juice.

On comparing (i) and (ii), we get

Independent variable: x=c

Dependent variable: y=s

Constant of proportionality: k=4

Therefore, the constant of proportionality is 4.

A culture is grown with a population of 45 million cells. The cell population is found to double every hour. What will the popul
Alexandra [31]
45 million * 2^{4} = 45million * 16 = 720million

Or you can use 
y=Ae^{kt}
A is equal to 45 million
To find the rate, k, we can plug in:
90million=45million*e^{k*1}

2=e^{k}
k=ln(2)
y=4.5*10^{7}*e^{t *ln2}
Knowing that t = 4
y = 4.5*10^{7}*e^{ln(2)*4}

y = 720 million
