Answer:

(3a^2-6a-1)-(5a^2-2a+3)

= 3a²-6a-1 -5a²+2a-3

=3a²-5a²-6a+2a-1-3

= -2a²-4a-4

On a sine function y = Asin(Bx) +C , the maximum value is 19 and the minimum value is -5. Which of the following must be the val

blagie [28]

Answer:

|A| - C = 5

Step-by-step explanation:

The maximum value that a sine function can have is 1, and the minimum value is -1.

With this information, to find the minimum value of y, we can use sin(Bx) = -1, and to find the maximum value, we can use sin(Bx) = 1. Then, we have that:

19 = A + C

-5 = -A + C

Summing both equations, we have:

14 = 2C

C = 7

Now, to find the value of A, we can use the first equation:

19 = A + C

19 = A + 7

A = 12

So the value of |A| - C is:

|12| - 7 = 12 - 7 = 5

yKpoI14uk [10]

if she recieived 13 bills and 4 are 10 $? then we have 13-4= 9 20$ bills

so 4x10 +9x20 = 40+180 = 220

So yes it's true

Mean absolute deviation of 75, 89, 145, 85, 80, 92, 104, 90, 100?

Mama L [17]

First, compute the mean: $m=\frac{75+89+145+85+80+92+104+90+100}9=\frac{860}9=95.555$

Next compute the absolute deviations for each datapoint:
|75-95.555|=20.555
|89-95.555|=6.555
|145-95.555|=49.445
|85-95.555|=10.555
|80-95.555|=15.555
|92-95.555|=3.555
|104-95.555|=8.445
|90-95.555|=5.555
|100-95.555|=4.445

Next we'll take the mean of these deviations: $\frac{20.555+6.555+49.445+10.555+15.555+3.555+8.445+5.555+4.445}9=\frac{124.665}9=13.8517$

The mean absolute deviation of your data is 13.8517
