Enter the number below in two other forms. Thirty thousand, five hundred eleven The number can be written in expanded form as The number can also be written in standard form as

a) In Expanded form = 30,511

b) In Standard form = 3.0511 × 10⁴

Step-by-step explanation:

We are given this number in words = Thirty thousand, five hundred eleven

a) Writing in Expanded form =

Thirty thousand + Five hundred + Eleven

= 30,000 + 500 + 11

= 30,511

b) Writing in Standard form = This mean writing a given number as an exponential or exponent of 10

We are given the number : Thirty thousand, five hundred eleven = 30,511

30,511 in standard form = 3.0511 × 10⁴

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
