Answer:
Is there a picture of the table I will try and solve but I'm not sure if I can
ANSWER:
We know that,
Speed = Distance/Time
So, Time taken = 20kmh-¹/160km
Answer:
Step-by-step explanation:
1. Find the slope: -1
2. Y = -x +b
3. Plug in a point
4. B is 1
5. The equation is Y=-1x+1
The correct question is
<span>A student uses the equation tanθ=s²/49 to represent the speed, s, in feet per second, of a toy car driving around a circular track having an angle of incline θ, where sinθ=½. To solve the problem, the student used the given value of sinθ to find the value of tanθ and then substituted the value of tanθ in the equation above to solve for s. What is the approximate value of s, the speed of the car in feet per second?

we know that
step 1
find the value of θ
sinθ=½.
θ=arc sin (1/2)--------> θ=30°
step 2
find the value of tan θ
tan θ=tan 30°
tan 30°=sin 30°/cos 30°
sin 30=1/2
cos 30=√3/2
so
tan 30=(1/2)/(√3/2)-----> √3/3
step 3
solve for s
tanθ=s²/49
√3/3=s²/49------> 49*√3=3*s²------> s²=[49*√3]/3----> s=√{[49*√3]/3}
s=5.3 ft/sec
the answer is
5.3 ft/sec
