The equation a = 100 + 75d represents Maria's  account balance.

<u>Step-by-step explanation:</u>

Given that,

  • Maria opened a new savings  account with an initial deposit of  $100.
  • She deposits $75 into this  savings account every  two-weeks.

You need to find the equation to represent Maria's  account balance, a after she has  completed d deposits.

  • Let 'd' be the number of deposits Maria made after the initial deposit.
  • Let 'a' be the total account balance after 'd' deposits.

Therefore, the equation for the total account balance can be framed as the sum of the initial deposit and amount deposited after that.

<u>To find the amount that was deposited after the initial deposit :</u>

⇒ $75 × number of times Maria deposited.

⇒ 75 × d

The equation is written as,

⇒ a = 100 + 75d

Hence the equation a = 100 + 75d represents Maria's  account balance.

A ______ involves both an experimental group and a control group, which are alike except for the one viable that the experiment
konstantin123 [22]

Answer:

controlled experiment

Step-by-step explanation:

Controlled experiment is a type of experiment in which except for only one variable, everything is kept constant.

The common type of the controlled experiment compares the control group against the experimental group. All the variables are identical between two groups except factor which is being tested.

Big advantage of the controlled experiment is that one can eliminate much of uncertainty about the results.

I am a bit confused on a derivative is in Calculus. From what I understand, I derivative is the limit of a tangent line on a cur
lakkis [162]

Answer:

Step-by-step explanation:

To answer your question fully can literally take up an entire  book.

The importance becomes obvious if you consider the derivative (and the inverse  of it the integral) as the foundation of calculus. I guess that askes the question what is calculus? For this answer a very very simplistic answer would be that it is the branch of mathematics that studies "non-constant" change (things that curve)

...... Let's see if  this makes sense? You are driving your car at a constant  50 mph . after one hour you are 50 miles from home and after two you are 100.

y=50x. you can calculate this value in a several of ways just take two time stamps and two distance stamps ... subtract the two times and two

ok now here is the REAL PROBLEM issue we want to know our CHANGE IN

VELOCITY (that is  ACCELERATION) ... if you take ANY two points you will

see that the SPEED is ALWAYS the same so the numerator is always 0 (zero) and thus the denominator (the difference in the time stamps) does not matter

now lets say that we are accelerating ..we are going y = 10 x^{2} mph

at 3 seconds we are going 90 mph (10* 3^2) .. but we really don't care about that   we want the "acceleration" at EXACTLY that point...

to do that we "have to estimate" delta Y over delta X

lets take 3 and 0  .... (9-0)/3 estimate of acceleration is 3...

but WAIT we can do better (get closer) take 3 and 1 ... (9 - 1)/2

acceleration is 4... once again lets get closer to the exact 3 ...

3 and 2  ... (9 -4)/2 the acceleration is 5...

hold on !  lets get even closer use 3 and 3 and we get it exactly !

(9-9)/0 that is the answer hurray!  HOLD ON !  you CAN NOT DIVIDE BY ZERO ... no can do... we have to wait for newton and Leibniz to  

figure out lim as x-> 0 f(x)-f(x+ delta x) / x to get around the DIVIDE BY ZERO problem...

that is the derivative

What does l-8l + l8l = this mean?
Viktor [21]
The |x| operator means 'absolute value' or the positive value of the negative values. To help this make sense, here's a visual representation:
|-8| = 8

But,
|8| = 8

Do you see what I mean? BTW, your answer will just be 8 + 8 or 16.
