9+10=k**l yourself

What does $1500 at 9% for 2 years mean?

In terms of interest and stuff,

FV=PV(1 + R)^N

FV=1500(1 +.09)^2

FV=1500(1.09)^2

FV=1500(1.1881)

FV=$1,782.15 Principal plus interest.

25\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)

Your Problem: 3x^2-75

First off you need to get that three out of there, factoring it out should be the best method.
 

3(x²-25)

For the next step ignore the 3 and focus on the rest (but in the end don't forget to add it back).

x²-25

Doesn't it look like a perfect square? Well it is. So for this step you must factor this simple equation into:

(x-5)(x+5)

Then put the three in like so and voilà:

3(x-5)(x+5)

You basicly want to use A=pe^rt to find the amount of money you now have. A is the total amount of money you have after a certian period of time (T) while your money grows at a steady rate (R). (E) is an irrational number 2.71828. (P) is the amount of money you started with. Your precentage is your rate and this means you earn 9% of what you have per year. The way the problem would be set up A=1500(2.71828)^(.09)(2). This problem allows for exponential growth to occur because your two variables are time and the amount you have in that time.

You have the correct derivative....

To find any possible max's or min's....set the derivative to 0

1 + sinx  = 0 

sin x  =  -1   and this happens at   -pi/2 on the requested interval

To see if this is  a possible max or min.....take the second derivative =  cosx

But putting the critical point of    -pi/2   into this produces 0....which  doesn't tell us anything

But this derivative  is always positive for any values except at -pi/2 + n2pi  [where n is an integer]....and at these points the derivative is 0........so..in simple terms.....the curve is constantly increasing from left to right except at these aforementioned points where its derivative is 0

So...this curve only has max's and min's at its enpoints....namely, a min at  x= -pi/2, and a max at x = pi/2

Here's a graph of the function to show this : https://www.desmos.com/calculator/kvylqvrime

if it's the hypotonus the answers is = c² = a² + b²

If it's not the anser is = a² = c² - b²

Assuming 3 2/3 cups of flour are used for one batch, 3 2/3 becomes 11/3 (denominator 3 times whole number 3 plus numerator 2 to make 3 2/3 a improper fraction)

11/3 *4/1= 14 2/3, or 44/3 

Li is going to need 14 2/3 cups of flour to make those 4 batches for his recipe

always glad to help

3x-2=8

3x-2+2=8+2

3x=10

3x/3 10/3

x=3.333333333333333333 (aka 3 1/3)

your welcome and good luck

So, Point A is (8,3) 

and the scale factor is 2/3, making it a reduction, or a smaller triangle, because the scale factor is less than 1, so you know that the coordinate is going to be plotted on a shorter scale

8 times by 2/3=5 1/3

3 times by 2/3=2 

(never divide while dilating, otherwise the numbers become way bigger)

the coprdinate for A' is (5 1/3, 2)

Guest is full of mule muffins.

d is the dollar and q is the quarter

 d + 0.25q = 153

 q+143 =d  

 q + 143 + 0.25q = 153

14300 + 100q + 25q =15300  |*100

125q = 1000

 q=8

And 8 +143 = 151

 d=151

Devons starting point-her house, 0 miles

devon goes to Andrews house-4.8 miles

andrews house to Roberts-.2 miles (5-4.8)

roberts to back home-5 miles

add the distances all up

4.8+0.2+5=10

Devon walked 10 miles in all

All you really have to do is do 312 divided by 6, and divide again by 4

width=volume/length/height (the order for length and height don't matter, and it's the same thing for length and width, like length=volume/height/width, height=volume/width/length, for volume=length*width*height)

312÷6÷4=13

to check work, multiply length times width times height to get volume, in this case the volume should be 312 if the width was founded correctly

13x6x4=312

the width of this rectangular prism is 13 inches

Well if the discount is 10%, then the sale price is 90% of the original price, cuz 100%-10%=90%, so all you have to do is $56,000.00*90%, but the real way to write it is 56,000*.9

And it should look like this: 56,000x0.9=50,400

to check, just do 504,000÷0.9=560,000

the sale price for the car is $50,400 

755 dollars

153/.25 = 612 (quarters)

612 + 143 = 755

2*4 = 8

the * means multiply if you didnt know

3 and 5 12ths times 2 and 25 hundredths times 2 

[ 3 + 5/12] * [ 2 + 25/100] * 2  =

[ 41/12] * [ 2 + 1/4] * 2  =

[41  / 12  ]  * [ 9 / 4 ] * 2  =

[41 / 4]  * [ 9 / 12 ] * 2  =

[ 41 / 4 ] * [ 18 / 12 ] =

[41 / 4 ] * [ 3 / 2 ] =

123 / 8
