<em>v₂ = 55mph</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em>Velocity formula</em>
<em>v = distance/time = d/t => d = vₓt</em>
<em>v₁ = v₂ - 11</em>
<em>t₁ = 10h</em>
<em>t₂ = 8h</em>
<em>d = v₁ₓt₁ = (v₂ - 11)t₁ </em>
<em>d = v₂t₂</em>
<em>(v₂ - 11)t₁ = v₂t₂</em>
<em>replace t₁ ; t₂</em>
<em>(v₂ - 11)10 = v₂8</em>
<em>10v₂ - 11ₓ10 = 8v₂</em>
<em>10v₂ - 8v₂ = 110</em>
<em>2v₂ = 110</em>
<em>v₂ = 55 mph</em>
<em>Good luck !</em>

Answer:
1/6
Step-by-step explanation:
if there are 6 sides on a dice and the space is 3 moves away, then you have a 1/6 chance of rolling a 3 and landing on it.
ANSWER
The dot product is 10.
EXPLANATION
The given vectors are (2,4) and (1,2).
If we have the vectors
u=(a,b) and v=(c,d)
Then the dot product of the two vectors is given by
This implies that,
This simplifies to;
Answer:
b = 3/4
Step-by-step explanation:
Using point slope: y - y1 = m(x - x1).
Substitute your given slope, given point, and subsitute 0 in for x and solve for y since the y intercept is the y value when x = 0.
0.2 = 1/5, so 1/5 * 1/4 = 1/20
Therefore: y - 4/5 = 1/4(0 - 0.2) → y - 4/5 = -1/20 → y = 4/5 - 1/20 → 15/20 → <em>3/4</em>
