Answer:
okay
Step-by-step explanation:
complementary angles are angles that add up to 90 degrees
so what you would do is take each number that you have and subtract it from 90
In the first one you would
1. take 90-80
2. you get your answer of 10!
i hope this helps :)
Not sure
te rate is r
for decay, it is
A=P(1-r)^t
r=rate
P=present amount
dunno what b is
but I guess
A=28000(1-0.13)^t
A=28000(0.87)^t
I would guess the decay factor would be 0.87
Answer:
Step-by-step explanation:
Given:
- Focus = (-5,-4)
- Directrix = -6
To find:
Locus of Parabola (Upward/Downward)
Where:
- (a,b) = focus
- c = directrix
Hence:
Cancel square root by squaring both sides as we get:
Solve for y-term:
Answer:
Yes
Step-by-step explanation:
If you replace each x with -3 and each y with 2 you get:
1) 2<-4*(-3)
2<12
True
2) -3+8*2>7
13>7
True
Therefore the point is part of the solution set
5.25, -16.75
I think it’s wrong
