Answer:
404.7
Step-by-step explanation:
You multiply 10.65 by 38 to get 404.7
Answer: 31
Step-by-step explanation:
so it's obvious, I guess :)
Now, let's prove is not rational number.
Proof by contradiction.
Let assume is a rational number. Therefore it can be expressed as a fraction where and .
is an even number, so must also be an even number, and therefore also must be an even number. So, we can say that , where .
Since is an even number, then also must be an even number. 3 is odd, so for to be an even number, must be an even number, and therefore is an even number.
But if both a and b are even numbers, then it contradicts our earlier assumption that . Therefore is not a rational number.
we have
we know that
The absolute value has two solutions
Subtract both sides
Step 1
Find the first solution (Case positive)
Subtract both sides
Multiply by both sides
Step 2
Find the second solution (Case negative)
Adds both sides
<u>Statements</u>
<u>case A)</u> The equation will have no solutions
The statement is False
Because the equation has two solutions------> See the procedure
<u>case B)</u> A good first step for solving the equation is to subtract 0.5 from both sides of the equation
The statement is True -----> See the procedure
<u>case C)</u> A good first step for solving the equation is to split it into a positive case and a negative case
The statement is False -----> See the procedure
case D) The positive case of this equation is 0.5 – |x – 12| = 0.25
The statement is False
Because the positive case is -----> see the procedure
case E) The negative case of this equation is x – 12 = –0.75
The statement is True -----> see the procedure
<u>case F)</u> The equation will have only 1 solution
The statement is False
Because The equation has two solutions------> See the procedure
Answer:
b = h cos α.
Step-by-step explanation:
sin β = b / h
b = h sin β.
or cos α = b / h
so b = h cos α.
