Karen invested $2,000 in a special savings account.

Mathematics
1 answer:
WARRIOR [948]2 years ago
4 0

Answer:

D. $512,000

Step-by-step explanation:

Well if the balance doubles every 5 years, then dividing 40 by 5 gives us the number of times the money will double, which is 8. We can then turn this into the equation 2000(2^{8}). 2^8 can be simplified to 256. Multiply that by 2000 and we get our answer, 512000. Hope this helps!

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

in a group of 40 student students, the probability that at most 15 of them like to hike? A 44% B 64% C 55% D 38%e to hike is 36%
shepuryov [24]

Answer:37.5% approximately 38%

Step-by-step explanation:

Probability formula= Number of possible outcome/ Total favorable outcome

Number of possible outcome=15

Number of total outcome =40

15/40×100=37.5 approx. 38%

Think about whether these ordered pairs represent a function. Then use the drop-
Lostsunrise [7]

Answer: All x-coordinates are different, so this relation is a function.

Having the same y value more than once is not a problem for a function.

"This (does not/does) represents a function because different (x values/y values) can have the same (x values/y values)."

PLS HELP ASAP PLS
Reika [66]
Hello!

To find surface area, all you need to do is add up the areas of all the faces of the prism. Let’s start by remembering some basic area formulas:

Area of a triangle= 1/2*base*height
Area of a rectangle= length*width

First, find the area of each of the little triangles on the sides of the net. The base is 3 ft, and the height is 4 ft. So:

1/2*3*4= 6 ft

There are two triangles of the same size, so multiply that number by 2.

6*2=12

Now, find the area of the top rectangle:

3*8= 24

And the area of the bottom rectangle:

5*8= 40

Finally, add all of those numbers together:

12+24+40= 76 ft^2

That should be your answer!
