A
- Harvard university professor
Answer:
y=-3x+5
Step-by-step explanation: y=mx+b
to find slope (m) use the equation 
so
= -3
to find b
use y=mx+b
-1=-3(2)+b
-1=-6+b
5=b
Hope this helps :)
This question is incomplete because it lacks the diagram of the right angles shaped charging stand.
Find attached to this answer, the appropriate diagram.
Answer:
3(tan 50°)
Step-by-step explanation:
To solve this question, we would be using the Trigonometric function called Tangent.
tan θ = opposite side/ adjacent side
θ = 50°
Opposite side (Height)= Side AC = Unknown
Adjacent side = Side BC = 3 inches
Hence,
tan 50° = Side AC/ Side BC
tan 50° = Side AC / 3
Cross multiply
tan 50° × 3 = Side AC
3(tan 50°) = Side AC
Therefore, the expression shows the height, AC, of the charging stand is
3(tan 50°).
