<span>integers are numbers that we get from adding and subtracting the number 1. Zero also belongs to integers .
</span><span>example
3 = 1+ 1 + 1
3 = 1 + 1 + 1 +1 - 1
0 = 1 + 1 - 1 - 1
- 4 = -1 - 1 - 1 -1
- 4 = 1 - 1 -1 - 1 - 1
</span><span>In this way you can get infinitely large number of total positive , negative and zero</span>
Answer:
- sin C=h/a
- substitution property of equality
- commutative property of multiplication
Step-by-step explanation:
Because two points determine a line, you can draw altitude BD perpendicular to AC with height h. By the definition of a sine ratio, <u>sin(C) = h/a</u>, which can be rearranged into a·sin(C) = h. The area of △ABC is A=1/2bh. The <u>substitution property of equality</u> can be used to write A=1/2b(a sinC), which becomes A=1/2ab(sinC) by the <u>commutative property of multiplication</u>.
___
The mnemonic SOH CAH TOA reminds you that the sine ratio is ...
Sin = Opposite/Hypotenuse
Here, the side of the right triangle opposite angle C is designated "h", the height of ∆ABC. The hypotenuse of that right triangle is side "a". So ...
sin(C) = h/a
__
The substitution property of equality lets you replace any expression with its equal. Here, we have h=a·sin(C), so we can use a·sin(C) in place of h in the formula for triangle area:
1/2bh = 1/2ba·sin(C)
__
The commutative property of multiplication lets you rearrange the order of the factors in a product, so ...
ba = ab
and
A = 1/2ba·sin(C) = 1/2ab·sin(C)
Answer:
-6
Step-by-step explanation:
Took test
15x
x is a variable meant to represent however many flower pots we end up selling, and we know each pot is $15. Therefore all we need to know is 15 times x.
Again, 15x
Answer:
y^2-5y-4
Step-by-step explanation:
Let y^2-5y+1 =A
Required polynomial=B
A-B=5
B=A-5
B=y^2-5y+1 -5
B=y^2-5y-4
Hence,Required polynomial=y^2-5y-4
