Answer: D, 50
y = kx <span>y = 20 and x = 0.4
</span>
What you will do: You will plug in your y and your x.
Your equation should look like: 20=k(0.4)
Next: What you will do is divide each side of your equal sign by 0.4 so you will get your k alone.
You would get: k=50
HOPE THIS HELPS! ^_^
Answer:
Sometimes
Step-by-step explanation:
Examples:
-5 + 10 = 5 FALSE
-10 + 5 = -5 TRUE
#7 is the easiest one.
a + bi = -9 + 4i
see the expression on either side matches up so..
a = -9 and b = 4
Answer:
I think it is D
Step-by-step explanation:
Answer:
x = 12.3
y = 15.9
Step-by-step explanation:
Apply trigonometric ratio to find x and Reference angle = 51°
Opposite side length = x
Adjacent side length = 10
Hypotensive length = y
✔️To find x, apply TOA:
Tan 51° = Opp/Adj
Tan 51° = x/10
x = Tan 51° × 10
x = 12.3 (nearest tenth)
✔️To find y, apply CAH:
Cos 51° = Adj/Hyp
Cos 51° = 10/y
y × Cos 51° = 10
Divide both sides by Cos 51
y = 10/Cos 51
y = 15.9 (nearest tenth)
