Answer:
Independent Variable: Number of hours
Dependent Variable: Cost
Equation: C = 2x + 6
Step-by-step explanation:
The independent variable (x) is the variable that is manipulated. In this instance, that would be the number of hours a person rents out the bike.
The dependent variable (C) is the variable that is manipulated depending on the value of the independent variable. In this instance, that would be the total cost for renting the bike.
The total equation would be C = 2x + 6. The coefficient, 2, represents the charge of $2 per hour and the 6 represents the starting charge of $6.
Answer:
it's a
Step-by-step explanation:
because its says four multiplied by eight
The |*| symbols take away the negative value of a number. So |-3| is just “3”. I can explain more if needed :)
Part a.
The drive had some files before the transfer. We don't know the number of megabytes already on the drive, so we call it x. x is the number of megabytes on the flash drive before Agent Hunt started the transfer.
He transferred files at a rate of 4.4 megabytes per second for 32 seconds. That gives a total of 4.4 Mb/sec * 32 sec = 140.8 transferred megabytes.
He ended up with 384 megabytes.
x + 140.8 = 384
Now we can solve for x, the number of megabytes originally on the flash drive.
x = 384 - 140.8
x = 243.2
The flash drive has 243.2 megabytes when the transfer began.
Part a. Answer: 243.2 megabytes
Part b.
The total capacity if the flash drive is 1000 megabytes. He already had 243.2 megabytes on it before this transfer. 1000 Mb - 243.2 Mb = 756.8 megabytes
The flash drive has capacity for an additional 756.8 megabytes when he started the transfer. The rate of transfer is 4.4 megabytes/second.
756.8/4.4 = 172
Part b. Answer: 172 seconds
The equivalent of sec (-270) will be found as follows:
we add our angle to 360°
-270+360
=90
But sec(-270) is a positive value, this implies that the angle that will give us the same answer as sec (-270) should also give us the positive value. This means that 90 is our answer since it will give us the positive sec value.
The answer is d. sec(90)
