Answer:
The third side =4
Step-by-step explanation:
I'm pretty sure it would be C
because 0.17 is how much he has to pay for each message sent and if x is the total messages he sends then it should be 0.17X+24.07
The center after enlargement using scale factor is (4.5,0.5).
What is Scale factor ?
The ratio between the scale of an original thing and a new object that is a representation of it but is a different size is known as a scale factor (bigger or smaller). For instance, if a rectangle has sides of 2 cm and 4 cm, it can be made larger by multiplying each side by a certain number, in this case 2.
Here the given coordinate point is,
=> (x,y)=(3,1)
Now enlarging the coordinator using scale factor k
=> (x,y)= (kx,ky)
Now put k=2 then
=> (x,y)=(0.5*3, 0.5*1)
=>(x,y) = (4.5,0.5)
Hence the answer is (4.5,0.5).

Answer:
Step-by-step explanation:
Let's find a solution by understanding the following:
The acceleration rate is defined as the change of velocity within a time interval, which can be written as:
where:
A=acceleration rate
Vf=final velocity
Vi=initial velocity
T=time required for passing from Vi to Vf.
Using the problem's data we have:
Vf=65miles/hour
Vi=6miles/hour
T=14.8seconds
Using the acceleration rate equation we have:
, but look that velocities use 'hours' unit while 'T' uses 'seconds'.
So we need to transform 14.8seconds into Xhours, as follows:
Using X=0.0041hours in the previous equation instead of 14.8seconds we have:
In conclusion, the acceleration rate is
The correct answer is 1 mm Hg per year.
