Answer:
The correct answer is 585 colories. I know it is correct because I tooked the quiz.
Hope it helps! :)
Answer:
18 : 39
Step-by-step explanation:
36 to 78
Divide both sides by 2.
=> 18 : 39
Suppose we want to know the total cost of buying x toys and we know that each toy costs $2. The relationship between the cost and the number of toys is
C(x) = 2x
If we purchase 6 toys, the cost would be
C(6) = 2*6 = $12
This is an example where it's adequate to use a single variable (or unknown) to find the value of another variable.
Now suppose we want to know the total cost of buying x toys for $2 each and include the tax rate in the calculations.
If we know the tax rate r, we can compute the total cost as
C(X,r) = 2x*(1 + r/100)
For example, to purchase x=6 toys and the tax rate is r=8%, the total cost is:
C(6,8) = 2*6*(1 + 8/100)=$12.96
If we had tried to calculate this cost without the use of two unknowns, it would have not been possible.
Thus, the pattern to use one or two variables depends on how many factors determine the final result.
Answer:
![- 6](https://tex.z-dn.net/?f=%20-%206)
Step-by-step explanation:
The given expresion is
![2 {x}^{4} - 3 {x}^{3} - 20 {x}^{2} - 6](https://tex.z-dn.net/?f=2%20%7Bx%7D%5E%7B4%7D%20%20-%203%20%7Bx%7D%5E%7B3%7D%20%20-%2020%20%7Bx%7D%5E%7B2%7D%20%20-%206)
We want to use synthetic division to find the remainder when the function is divided by x-4.
We write out the coefficient of the function and perform the synthetic division as shown in the attachment.
The remainder is the last number in the last row which is -6.
The correct angle for x is 135 degrees.
