Answer:

sin(H)=0.91

Step-by-step explanation:

<u><em>The question is</em></u>

Right triangle FHG is shown. The cosine of ∠F is 0.91. What is the sine of ∠H?

The triangle FHG is a right triangle

we know that

If two angles are complementary, the co-function identities state that the sine of one equals the cosine of the other and vice versa

In this problem

∠F and  ∠H are complementary angles (their sum is equal to 90 degrees)

so

sin(H)=cos(F)

sin(F)=cos(H)

we have

cos(F)=0.91

therefore

sin(H)=0.91

In bookkeeping, an account is represented by a single page in a ledger, and any changes in value are chronologically documented using debit and credit entries.

These entries, which are also known as posts, are added to a book of final entries or ledger and form a part of it.

18 * 8 = 144

Therefore

x=200 - 144

x = $56

The simplest form of the expression -2x2(x – 5) + x(2x2 – 10x) + x is
Bad White [126]
For this case you must simplify the expression respecting the rules of multiplication of mathematics.
 The steps to simplify the expression are the following:
 First multiply what is in the parentheses
  -2x ^ 2 (x - 5) + x (2x ^ 2 - 10x) + x
  -2x ^ 3 + 10x ^ 2 + 2x ^ 3 - 10x ^ 2 + x
 Then add the terms that have the same exponent
 (-2x ^ 3 + 2x ^ 3) + (10x ^ 2 - 10x ^ 2) + x
  x
 The final simplification is
