Answer:
x = 5, <DEG = 112, <GEF = 68, <DEF = 180
Step-by-step explanation:
<DEG + <GEF = 180
23x - 3 + 12x + 8 = 180
35x + 5 = 180
Subtract 5 from both sides
35x = 175
Divide each side by 35
x = 5
Plug x = 5 into <DEG
23x - 3
23(5) - 3
<DEG = 112
Plug x = 5 into <GEF
12x + 8
12(5) + 8
<GEF = 68
<DEF is a straight angle so it automatically is 180
Answer: Ian's height = x+14 = 69+14 = 83 cm
Explanation :
Let the height of Jim be x
Let the height of Ian be x+4
Let the height of Lisa be x+4+10=x+14
Since their heights increase by 2cm every months
so after 7 months ,
Jim's height = x+14
Ian's height= x+4+14=x+18
Lisa's height= x+14+14=x+28
According to question,
Sum of Ian's and Jim's height = 170cm
⇒x =
⇒ x= 69cm
∴ Ian's height = x+14 = 69+14 = 83 cm
Answer:
eccentricity; e = 1/7
k = 12
Conic section; Ellipse
Step-by-step explanation:
The first step would be to write the polar equation of the conic section in standard form by multiplying the numerator and denominator by 1/7;
The polar equation of the conic section is now in standard form;
The eccentricity is given by the coefficient of cos theta in which case this would be the value 1/7. Therefore, the eccentricity of this conic section is 1/7.
The eccentricity is clearly between 0 and 1, implying that the conic section is an Ellipse.
The value in the numerator gives the value of k; k = 12
