Answer:
Step-by-step explanation:
2ft=24in
The first day 24(1/6)=4in fell
The second day 24(7/12)=14in fell
The third day 24-4-14=6in fell
Answer:
Correct choice is B.
Step-by-step explanation:
Plot the data from the given table on the coordinate plane.
Note that option C and D represent the quadratic and linear regressions (not exponential), thus, these options are false.
Plot both graphs from options A and B. The exponential regression from option A is shown by red curve (see attached diagram) and the the exponential regression from option B is shown by blue curve. As you can see the green points better suit blue curve, thus, option B is correct.
<u>Remark:</u>
Note that
are greater than 1.03, then option A is false.
Answer:
2, 70
Step-by-step explanation:
It is given that :
At Nolan's Car rentals, if a customer rents a car, he or she has to pay $60 for the car for the first day and more $ 5 for every additional days.
Therefore this gives the equation :
y = 5x +60 ..........(1)
At Westford car rental, the price of the car for first day is $ 50 and additional $10 for every additional day.
So the equation will be :
y = 10x + 50.......(2)
Solving (1) and (2), we get
5x + 60 = 10x + 50
⇒ 60 - 50 = 10x - 5x
⇒ 10 = 5x
∴ x = 2
Now putting the value of x = 2 in equation (1), we get
y = 5x +60
y = 5(2) +60
y = 70
Therefore, (x, y) = (2, 70)
I'll do part (a) to get you started.
The angle 'a' pairs up with the 123 degree angle as a corresponding angle pair. Due to the parallel lines, the corresponding angles are congruent. Therefore a = 123.
We also see that b = 123 as well since a = b (they are vertical angles).
Notice how angle c is adjacent to the 123 degree angle. These two angles form a straight line, so they must add to 180 degrees.
c+123 = 180
c = 180-123
c = 57
-------------------------
To summarize, we have these three angles
a = 123
b = 123
c = 57
