-Can you write an equation that relates quarts of blood to weight?
-How can you use the equation to determine solution?
Step-by-step explanation:
Given that amount of blood is directly linked to body weight of the person.
b = Amount of blood
W = weight of the person
k = proportionality constant or constant of variation
1) Given that, person who weighs 160 lb has about 4.6 quart of blood.
b = 4.6 quart, W = 160 lb
The constant of variation is of value 0.02875 quart/lb.
2) An equation that relates quarts of blood to weight:
3) If, b = ?,W = 175 lb
5.03125 quarts of blood are in the body of a 175-lb person.
–32 + _____ = 2(x2 + 10x + 25)
18 = 2(x + 5)2
9 = (x + 5)2
± _____ = x + 5
x = –2 or x = ____
_____=missing pieces
The steps used in completing the square of the given quadratic equation have been detailed below.
The first step given is;
- 32 = 2(x² + 10x)
The next step is to add a square of half the coefficient of x. Which in this case is 50 to both sides.
Second step is;
-32 + 50 = 2(x² + 10x + 25)
Third step is to further simplify the left and favtorize the right to get;
18 = 2(x + 5)²
9 = (x + 5)²
Fourth step is to take square root of both sides to get;
±√9 = x + 5
±3 = x + 5
Thus;
x = - 2 or x = - 8

B.) y= sin pi/520 theta
C.) y= sin 520/pi theta
D.) y= sin pi/260 theta
Please help
Answer:
Where k represent the number of wave and represent the angular frequency with T the period.
For this case we know tha T = 520 nm
And the angular frequency would be given by:
So then the possible anwer for this case would be:
D.) y= sin pi/260 theta
Since is the only option with satisfy the general equation of a wave.
Step-by-step explanation:
Since the sine function can be used to model light waves we can use the following general expression:
Where k represent the number of wave and represent the angular frequency with T the period.
For this case we know tha T = 520 nm
And the angular frequency would be given by:
So then the possible anwer for this case would be:
D.) y= sin pi/260 theta
Since is the only option with satisfy the general equation of a wave.
