Answer:
C
Step-by-step explanation:
5a - 3b^2 - a + b - 5 + 8a^2
8a^2 - 3b^2 + 4a + b - 5
The total area of a box is the sum of all the area of the faces it has. It is also called the surface area. The area of one face of a rectangular box is equal to the product of its length and width. So, the total area would be:
SA = 2lw + 2wh + 2lh
SA = 2(4)(3) + 2(3)(6) + 2(4)(6)
SA = 108 ft^2
The answer is D 1,400,000
To convert from scientific notation to standard notation you can just move the decimal point to the right how ever many times 10 is the the power of.
Answer:
100π
Step-by-step explanation:
We have to find the height. Since we have the base and hypotenuse of the triangle, we can use the Pythagorean Theorem to find the side. We have c^2 - a^2 = b^2; 13^2 - 5^2 = 144; sqrt144 = 12. The height is 12 and the radius is 5, so using V = (1/3)πr2h, we get (1/3)π(25)(12) = 100π
Answer:
4, 7, 12, 19 and 103
Step-by-step explanation:
Substitute n = 1, 2, 3, 4, 10 into the n th term formula, that is
1² + 3 = 1 + 3 = 4
2² + 3 = 4 + 3 = 7
3² + 3 = 9 + 3 = 12
4² + 3 = 16 + 3 = 19
Thus the first 4 terms are 4, 7, 12, 19
10² + 3 = 100 + 3 = 103
Thus the 10 th term is 103
