Step-by-step explanation:
1.√2×(-2√9)×(-√2)
= -2×(-2×3)
=12 option a
2. √5×√15×√75
= √5×(√3√5)×(5√3)
= 5×3×5
=75 option b
Answer: answer is C because if you do 2x9 abd 2x3 you 18c-6d and you cant subtract thise cause they have different variables
Step-by-step explanation:
Answer:
<u>1260 degrees (1260°)</u>
Step-by-step explanation:
<u>Formula to Find Sum of Interior Angles of a Polygon</u>
- 180 (n - 2)
- n is the <u>number of sides</u> of the polygon
<u>Nonagon (9-sided polygon)</u>
- 180 (9 - 2)
- 180 × 7
- <u>1260 degrees (1260°)</u>
Distance from focus to vertex=distance from vertex to directix
from (6,2) to y=1, the distance is 1
the focus is 1/2 higher than the vertex
vertex=(6,1.5)
for
(x-h)^2=4p(y-k)
vertex=(h,k)
p=distance from vertex to directix
vertex=(6,1.5)
ditance=0.5
(x-6)^2=4(0.5)(y-1.5)
(x-6)^2=2(y-1.5) is the equation
or
y=0.5x^2-6x+19.5 or
y=0.5(x-6)^2+1.5
