Ive got these two classes to choose from for next year, which would you say is more enriching and useful?-Depends on what you want to do with your maths... Obviously if youre going to be a statisticia
1/6 + 9/11
first you would have to find a common denominator (in this case, that would be 66.)
1/6 = 11/66
9/11 = 54/66
11/66 + 54/66 = 65/66
the answer is 65/66-First, determine the lowest common
(x+10)^2/100 + (y-6)^2/81 =1
and how do you know?-Its an ellipse with its center at the point (-10,6).Its an ellipse because of the plus sign.It would be a hyperbola if it was
(x + 10)²/100 - (y - 6
To qualify as a prime, a number must be divisible by 1 and itself, so 1 does not qualify. 2 is the first prime.-No, one (1) is not a prime number.
A prime number is defined as being a natural number
6S4 1/(((t^2) - 9) ^ (1/2)) dt
integrate 1 over the square root of t squared- 9 ....from 4 to 6
im using u sub and i get 36(sqrt3) - 8(sqrt7) , its wrong and the real answer has a natural log, not s
Write down a percentage that is bigger than a half and less than three-quarters.
Thanks.-1/2 * 100 = 0.50 * 100 = 50%
3/4 *100 = 3 * 25 = 75%
Any percentage between 50% and 75%. For example, 60%-Wri

........a
Here are offered answers:
A) a-1/a
B) a+1/a
C) 5a-1/a
D) 5a+1/a
He got the right answer as C, but the solutions say the cor
First, since x is a common factor of all three terms, factor it out to get:
10x^3 - 3x^2 - x = x(10x^2 - 3x - 1).
Then, by factoring by grouping, we have:
10x^2 - 3x - 1
= (10x^2 - 5x) + (2x - 1), b

How do I figure it out?-4cos^4(x) = 4{1 - sin^2 (x)}^2
= 4{1 - 2sin^2 (x) + sin^4 (x)}
sin(x) is an infinite series [x - x^3/3! + x^5/5! - ..........]
The only integer without variable x is 4 .-4co
