The type of variation between the speed and time is inverse.
The equation is r = d / t
The number of miles travelled is 102 miles.
<h3>What is the type of variation?</h3>
When the speed a person is driving at increases, the time it takes to travel would decrease. On the hand, speed a person is driving at decreases, the time it takes to travel would increase. This means that there is an inverse relationship.
The equation that represents an inverse relationship is
r = d / t
Where d is the distance
Distance = t x r
51 x 2 = 102 miles

Answer:
vertex, (4, –2); y-intercept, –6
Step-by-step explanation:
The equation is written in vertex form 
where the vertex is (h,k).
The vertex here is (4, -2). This means the solution is vertex, (4, –2); y-intercept, –6.
Answer:
sin x = 0.998
cosx = 0.046
Step-by-step explanation:
<u>Given that:</u>
tan x = 21
where interval of x is ![[0,\dfrac{\pi}{2}]](https://tex.z-dn.net/?f=%5B0%2C%5Cdfrac%7B%5Cpi%7D%7B2%7D%5D)
.
We know that the trigonometric identity for tan x is:
Comparing with:
Perpendicular = 21 units
Base = 1 unit
As per pythagorean theorem:
interval of x is so values of sinx and cosx will be positive because it is first quadrant where values of sine and cosine are positive.
We know that
So, sine x :
Similarly, value of cos x :
3 + (-8) - 17
3 - 8 - 17
3 - 25
-22 <==
