Answer:
d = ±7i
Step-by-step explanation:
d^2 -1 = -50
Add 1 to each side
d^2 -1 = -50
d^2 = -49
Take the square root of each side
sqrt(d^2) = sqrt(-49)
d = sqrt(-1) sqrt(49)
d = i( ±7)
d = ±7i
Inverse variation: y=k/x
1. plug in the values: (15,1)
1=k/15
2. solve for k
3. Now, plug in what you can for the second point: (n,5)
5=k/n (if you do the step above, you will know “k”.
4. Solve for “n”
Answer:
Yo
So, if ya wanna solve this question and of course questions alike, ya gotta pay attention to the graph. mean All of these parabolic chart have the domain of R
Step-by-step explanation:
So there ya go
D=R
and now bout the range ya gotta find the vertex, which is:

now pay attention
X=2/–2=–1
y=–(–1)²–2(–1)+3=4
Now the highest point of your parabolic chart is 4 and the lowest point is endless which is (–♾,4]
Well, finally your answer is D
Answer:
Angle RTS
Step-by-step explanation
Say it out loud it goes, RS, ST.
If you put RS and ST together the angle RTS
