Answer:
The correct option is (a).
Step-by-step explanation:
The vertices are equidistant from the circumcenter.
Circumcenter of a triangle is a point where the perpendicular bisectors are intersection each other.
In figure (a) the point P is the intersection point of all perpendicular bisector, therefore point P is the circumcenter of triangle ABC and the point P is equidistant from A,B and C.
Therefore option (a) is correct.
In figure (b) the point P is the intersection point of all perpendicular, therefore point P is not the circumcenter of triangle ABC.
Therefore option (b) is incorrect.
In figure (c) the point P is the intersection point of all bisectors, therefore point P is not the circumcenter of triangle ABC.
Therefore option (c) is incorrect.
In figure (d) the point P is the intersection point of all medians, therefore point P is not the circumcenter of triangle ABC.
Therefore option (d) is incorrect.
Answer:
4
Step-by-step explanation:
First you need to evaluate the power (exponent).
1 raised to any power is still 1.
Then you need to divide the equation
2 + 6 ÷ 3 ÷ 1
2 + 2
4
Answer:
Step-by-step explanation:
To solve this problem you should follow the PEMDAS rule, which is parentheses, exponents, multiplication, division, addition, and subtraction.
cos(θ) =
tan(θ) =
csc(θ) =
sec(θ) =
cot(θ) =
Answer:
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
The point (8, -15) shows it is in 4th quadrant.
side X is 8 and side Y is -15.
We can find side R with help of Pythagorean theorem.
Taking square root,
sinΘ=
cosΘ=
tanΘ=
cscΘ=
secΘ=
cotΘ=

Answer:
The value of the proportionality constant (y to x) is: 3/10
Step-by-step explanation:
We know the slope of any graph where 'y' varies directly with 'x' gives us the constant of proportionality 'k'.
i.e. y = kx
and k = y/x
Given the points
We know that the proportionality constant (y to x) is:
k = y/x
For the point (100, 30)
k = 30/100=3/10
For the point (300, 90)
k = 90/300=3/10
For the point (500, 150)
k = 150/500=3/10
As the value of proportionality constant (y to x) is the same.
i.e. k = 3/10
Thus, the value of the proportionality constant (y to x) is: 3/10
8x+3y=7
3x+5y= -9
No, the triangular numbers are not a direct variation. There is not a constant of variation between a number and its position in the sequence. The ratios of the numbers to their positions are not equal. Also, the points (1, 1), (2, 3), (3, 6), and so on, do not lie on a line.
