Given:
A car traveled 150 km in 3 hour.
To find:
The unit rate.
Solution:
We have,
Distance = 150 km
Time = 3 hours.
In this case speed is the unit rate.
Substituting the given values, we get
Therefore, the unit rate is 50 km/h.
I don’t know but i hope you have a good day
Answer:
a) the time speed for distance from the television camera to the rocket is changing at rate of 360 ft/sec
b) camera’s angle of elevation changing at the rate of 0.096 radians/ sec
Step-by-step explanation:
details and step by step explanation is in the images below
image I is for Solution of a)
image 2 is for Solution of b)
For this case we have the following function:
By definition, the domain is given by all the values for which the function is defined.
The given function is no longer defined if the argument of the root is negative. So:
Thus, the domain of the function is given by all the values of x greater than or equal to -3.
Domain: [-3, ∞)
Substituting the values of the domain, we find the range.
The function evaluated in ∞ gives -∞. So the range is given by:
(-∞, 2]
Answer:
Domain: [-3, ∞)
Range: (-∞, 2]
Answer:
1/6p - 4/5
Step-by-step explanation:
we combine like terms, so the numbers with p's are added together, and the regular numbers are added together too
we have to make -2/3 and 5/6 the same denominator, so multiply each number in -2/3 by two, giving you -4/6
-4/6p+5/6p=1/6p
simply do 1/5-1 which equals -4/5
put both solutions into one equation= 1/6p - 4/5
