Answer:
A = P(1 + r/100)^n
A = 1000 x (1.08)^n
Step-by-step explanation:
n is the number of years, p is the principal, A is the amount.
The lamp is appreciating (increasing in value) so every year, its value is 1.08 times its value the year before.
Use the first equation to be more general, use the second equation if there isn't anything below asking you to input numbers into the equation.
Probably just use the first one.
Answer:
Step-by-step explanation:
4y2 - 2x + 7 + 2y for x = 7 and y =2.
= 4(2)^2 -2(7) +7 + 2(2)
= 4(4) - 14 +7 + 4
= 16 - 14 + 7 + 4
= 13
Answer:
You will need 1400 cm² of paper
Step-by-step explanation:
When you wrap a gift, you wrap around the entire object. We need to find the total surface area of the prism. A rectangular prism has two rectangular faces on the end. The area of one of those faces is Height (of the prism) times Width.
Rectangular prisms also have 4 sides which are composed of rectangles. The area of one of those rectangles is length (of the prism) by the width.
Now we just need to sum up all of those areas.
![A = 2(H*W) + 4(L*W)\\A = 2(10*14) + 4(20*14)\\A = 2(140) + 4(280)\\A = 280 + 1120\\A = 1400](https://tex.z-dn.net/?f=A%20%3D%202%28H%2AW%29%20%2B%204%28L%2AW%29%5C%5CA%20%3D%202%2810%2A14%29%20%2B%204%2820%2A14%29%5C%5CA%20%3D%202%28140%29%20%2B%204%28280%29%5C%5CA%20%3D%20280%20%2B%201120%5C%5CA%20%3D%201400)
