Answer:
B.(-6,-1)
Step-by-step explanation:
Write the decimal number as a fraction ( over 1 ) 1.49=1.49/1
Multiplying by 1 to eliminate 2 decimal places we multiply top and bottom by 2 10s
Numerator ( N)
N= 1.49*10*10=149
Denominator(D)
D+ 1*10*10=100
N / D =149/100
Simplifying the fraction:
149/100
149/100
1 49/100 ( Final Answer )
Answer:
b = 17
Step-by-step explanation:
The angle bisector of the apex angle of an isosceles triangle is also a median and altitude. PS=RS=17
b = 17
4-(5[-1])+4=13 you must use order of operations even here
Answer:
20.6
Step-by-step explanation:
Given data
J(-1, 5)
K(4, 5), and
L(4, -2)
Required
The perimeter of the traingle
Let us find the distance between the vertices
J(-1, 5) amd
K(4, 5)
The expression for the distance between two coordinates is given as
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((4+1)²+(5-5)²)
d=√5²
d= √25
d= 5
Let us find the distance between the vertices
K(4, 5), and
L(4, -2)
The expression for the distance between two coordinates is given as
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((4-4)²+(-2-5)²)
d=√-7²
d= √49
d= 7
Let us find the distance between the vertices
L(4, -2) and
J(-1, 5)
The expression for the distance between two coordinates is given as
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((-1-4)²+(5+2)²)
d=√-5²+7²
d= √25+49
d= √74
d=8.6
Hence the total length of the triangle is
=5+7+8.6
=20.6
