False.
An exponential growth is a function of the form:
y = A (b) ^ (k * t)
Where,
k> 0
b> 1
Because the value of b> 1 means that the function grows.
Therefore, the answer to the question is false, because if k = 2 but b <1 then the function decreases.
Answer:
False

Please help, no links. PLEASE!!!!

There is a thousand answer to this problem.

Let's do the simplest one here.

f(x) or y = x - 1

f(x) or y = x + 1

f(x) or y = -x

Wait, would this count as a solution? : See the second attachment

At one gym, there is a $12 start-up fee, and after that each month at the gym costs $20. At another gym, it costs $4 to startup,

mart [117]

Answer:

In 4 months the cost of both gyms will be the same.

Step-by-step explanation:

At first we need to model the function to calculate the cost of the 2 gyms.

Slope-intercept equation of linear function

$f(x)=mx+b$

where

$m\rightarrow$ slope of line

$b\rightarrow$ y-intercept

Let linear function to calculate total cost of gym be:

$c(n)=mn+b$

where

$c\rightarrow$ total cost of gym

$m\rightarrow$ cost per month (slope)

$n\rightarrow$ number of months

$b\rightarrow$ start-up fee (y-intercept)

For Gym 1

$m=20$ , $b=12$

$c(n)=20n+12$

For Gym 2

$m=22$ , $b=4$

$c(n)=22n+4$

In order to find the number of months the cost of both gyms will be the same, we need to equate both functions and solve for number of months $(n)$

$20n+12=22n+4$

$\\\textrm{Subtracting 22n from both sides}\\20n-22n+12=22n-22n+4\\-2n+12=4\\\textrm{Subtracting 12 from both sides}\\-2n+12-12=4-12\\-2n=-8\\\textrm{Dividing both sides by -2}\\\frac{-2}{-2}n=\frac{-8}{-2}\\n=4\textrm{ months}$

So,

In 4 months the cost of both gyms will be the same.

Perform the indicated operation (-2i+3i)+(-1-4i)

Shtirlitz [24]

Answer:

-1 -3i

Step-by-step explanation:

It is unusual to have two imaginary terms grouped together like this. Taking the question at face value, we treat i as though it were a variable, and collect terms in the usual way.

(-2i +3i) +(-1 -4i) = i(-2+3-4) -1 = -1 -3i

what is true about every rotation? the image and pre-image are congruent. the image is larger than the pre-image. the image over

Rudiy27

I think the correct answer from the choices listed above is the first option. The statement that is true for every rotation would be that the image and pre-image are congruent. All the rest deals with changing the rotated shape not a constant. Hope this helps.
