Answer:
When you substitute 0 for the exponent x, the expression simplifies to a times 1, which is just a. This is because any number to the 0 power equals 1. Since the initial value is the value of the function for an input of 0, the initial value for any function of this form will always be the value of a

Answer:
Step-by-step explanation:
We need to solve the following root equation:
![\sqrt[3]{x-1} + 2 = 0](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx-1%7D%20%2B%202%20%3D%200)
1. First, we need to add minus two to both sides of the equation:
![\sqrt[3]{x-1}= -2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx-1%7D%3D%20-2)
2. Elevate each side of the equation to the power of 3:
3. Solve for 'x':
Therefore, the result is:
✔️
Answer:
1050 masks per person.
Step-by-step explanation:
1) Create an equation to find the total number of masks
2) Solve equation and divide total by 2 to get the number of masks that can be given to both Mark and Paula so that they have equal number.
1) Since Paula has 70% of the total masks, it can be represented as 0.7 * t where t is the variable representing the total number of masks. Mark on the other hand has the remaining number of masks out of 100% which is 30%. We can express that as 0.3. We multiply that by t because he has 30% of the masks. The final equation we have is 0.3t + 840 = 0.7t. 840 because Paula has 840 more masks than Mark.
2) Solve by subtracting 0.3t from both sides leaving you with 0.4t = 840. We divide both sides by 0.4 to get 2100. That is the total number of masks. If we divide that number by 2, we get 1050.
