6x7x4= 168
Answer:
H = 3.46
Step-by-step explanation:
By applying mean ratio theorem in the given triangles,
AD² = BD × DC
AD² = (6 - 4) × 4
AD = √8
AD = 2√2
By applying Pythagoras theorem in ΔABD,
Hypotenuse² = (leg 1)² + (leg 2)²
AB² = AD² + BD²
H² = (√8)² + 2²
H² = 8 + 4
H = √12
H = 3.46
Answer:
(3 and 15)
Step-by-step explanation:
If the product of both of these two numbers needs to be a negative 45 then there are no pair of integers that comply with both requirements.
If the multiplication in the question is wrong and it is a positive 45 then the pair of integers that would comply with these requirements would be (3 and 15). Multiplying this pair together would give you 45 and the difference between them is also 12 meaning it complies with both requirements that were asked for in the question.
What are the advantages of the parametric equations
Answer:
Step-by-step explanation:
Parametric equations shows the relation between a group of quantities by expressing the coordinates of points of a curve and function as one or more independent variables.
From the question given; the advantages of parametric equations given
x = 1 + 6 cos t
y= -2 + 6 sin t
are
:
1) For a given value of the independent variable the parametric equation is used exactly one point on the graph
2) the parametric equations have a finite domain
3) the parametric equation is easier to enter into a calculator for graphic
