Answer:
-5.5
Step-by-step explanation:
2.75+(-2)+(-6.25)=-5.5
Answer:
True
Step-by-step explanation:
We need to verify whether 15 and 20 are the correct solution to the rule of "The difference between the 2 number is 5 and the number are in the ratio 3 : 4". Let's see,
<u>First rule</u> → The difference between the 2 numbers is 5
20 - 15 = 5 ⇒ Correct
<u>Second rule</u> → The numbers are in the ratio 3 : 4
15 : 20 ( ÷ 5 to both ratio's ) 3 : 4 ⇒ Correct
Answer:
hello : 160°
Step-by-step explanation:
8pi/9 = (8×180°)/9 = 160°
Answer:
X=12
Step-by-step explanation:
Add the two equations together and equate them to 180 due to the geometrical reason that angles on a straight line add up to 180.
10X-20+6X+8=180 (collect like terms)
10X+6X=180-8+20
16X=192 (Divide both sides by 16)
X=12
Hope that helps :)
Yes it is true that point , line and pair of intersecting lines are special cases of conic sections
They are actually degenerate cases of intersection that occurs in special conditions.
Lets get into a bit detail one by one
A single point - when the plane which cuts the surface of cone only passes through apex
Again when the plane passes through apex and another point on the cone
it produces one straight line or two intersecting straight lines.
