I open a savings account with 25$. I deposit the same amount from my check each month. After 6 months, I have 235$ in my savings

account. Assuming a constant rate of change, write a linear function that represents the amount of money in the savings account s(x) , as a function of the number of months x​

Answer:

s(x) = 25 + 35x

Step-by-step explanation:

We calculate the difference between the initial deposit and 6 months.

235 - 25 = 210

We calculate the amount per month of the deposits.

210 / 6 = 35

s(x) = 25 + 35x

Answer:

c for the question that says what point is on y=\log_a(x) given the options.

9  for the question that reads: "If \log_a(9)=4, what is the value of a^4.

Step-by-step explanation:

We are given y=\log_a(x).

There are some domain restrictions:

a \text {is number between } 0 \text{ and } 1 \text{ or greater than } 1

x \ge 0

a) couldn't be it because x=0 in the ordered pair.

b) isn't is either for the same reason.

c) \log_a(1)=0 \text{ because } a^0=1[/tex]

So c is so far it! Since (x,y)=(1,0) gives us 0=\log_a(1) where the equivalent exponential form is as I mentioned it two lines ago.

d) Let's plug in the point and see: (x,y)=(a,0) implies 0=\log_a(a).

The equivalent exponetial form is a^0=a which is not true because a^0=1 (\neq a).

If \log_a(9)=4. then it's equivalent exponential form is: a^4=9.

Guess what it asked for the value of a^4 and we already found that by writing your equation \log_a(9)=4 in exponential form.

Note:

The equivalent exponential form of \log_a(x)=y implies a^y=x.

Answer:

box 1 = 30

Step-by-step explanation:

it is because it shows us that the 30 x and 45 y meet at same point and x is area which means box 1 is 30 and y is cost so box 2 is 45

Answer:

0.4

Step-by-step explanation:

x=\frac{d}{2} =\frac{2.4}{2}  =1.2\\
