Im having trouble finding facts that are in scientific notation. a good example is: a microbe is 1.23*10^-3 small. (this is not a real fact I just made this up.)

Solve the equation: 2 * x-3 = 25, x =? (digit answer):

A ball is thrown vertically upward from the ground with an initial velocity of 122 ft/sec. Use the quadratic functionh(t) = -16t2 + 122t +0 to find how long it will take for the ball to reach its maximum height, and then find themaximum height. Round your answers to the nearest tenth.

A local electronics store raised its prices on headphones by 20%. The headphones that Stan wants to buy now cost $36. How much did the headphones cost before the price increase?

10x=1.1...

x=0.1...

Then subtract the two equations from each other:

9x=1

Solve for x:

x=1/9

x=0.1...

Then subtract the two equations from each other:

9x=1

Solve for x:

x=1/9

**Answer:**

**First is 5 +8 = 13 and Second is 8 +5 = 13 .**

**Step-by-step explanation:**

Given : 5+8.

To find : Write two ways you could use to find 5+8 .

Solution : We have given that 5 + 8.

First is 5 +8 = 13

Second is 8 +5 = 13 .

**Therefore, First is 5 +8 = 13 and Second is 8 +5 = 13 .**

Addition is commutative.

3 + 4 = 7. = 4 + 3

Division is not commutative.

3 / 4 is not = 4 / 3.

3 + 4 = 7. = 4 + 3

Division is not commutative.

3 / 4 is not = 4 / 3.

Given, soccer field length is 40 m longer than width

lets consider width=w

so, length = w+40

area = length*width=6000

(w+40)*w=6000

w^2 +40*w-6000=0;

w^2+(100*w-60*w) -6000=0

(w^2 + 100*w) - (60*w+6000)=0

w(w+100)-60(w+100)=0

(w+100)(w-60)=0

w=60, because width will not be '-100'

w=60 and L=60+40=100

lets consider width=w

so, length = w+40

area = length*width=6000

(w+40)*w=6000

w^2 +40*w-6000=0;

w^2+(100*w-60*w) -6000=0

(w^2 + 100*w) - (60*w+6000)=0

w(w+100)-60(w+100)=0

(w+100)(w-60)=0

w=60, because width will not be '-100'

w=60 and L=60+40=100

Area of a triangle is (basexheight)/2

That's what your Formula, then you have to plug in the numbers

so the algebraric expression is (5xn)/2

For then end if you look at the patteren for the height it goes by 2. So the last height would be 10.

Plug that into the equation, which would be (5x10)/2=25
