Answer:
» Collect like terms, r terms on the left hand side by subtracting r from both sides and adding st to both sides
» On the left hand side, factorise out r
I suppose you mean 5y^8.
When y = 4, we have,
5(4)^8 = 5 x 65,536 = 327,680
for example lets use 3^2 + 4^2, you add the main numbers, 3 and 4 to get 7, then there are still the exponents, the squared signs, they don't change, they stay as a two. If your problem required a single whole number, then you have to square the 7, 7*7 is 49, so that or 7^2 would be your final answer.
Answer:
The table of Henry's family will be at (4, -4)
Step-by-step explanation:
The problem states that the initial coordinates of Henry's family is at the coordinates (-4, 4). Each 15 minutes the restaurant will rotate 90° every 15 minutes. If we follow the Cartesian plane and the center of the restaurant being at (0, 0) we know that the table will be situated at the (4, 4) coordinates of the restaurant after the first rotation. After the 30 minute mark, the restaurant rotates one more time and moves the table of Henry's family at the (4, -4) coordinates of the restaurant as the center of the restaurant will never move.
The answer is 68 inches. The mean is the average, so you would need to add all the numbers (408), and divide by how many there are (6) which will give you 68.
