Answer:
34
Step-by-step explanation:
(3 + 5i)(3 - 5i) = 9 - 25i^2
because i^2 = -1 9 - 25i^2 = 9 - 25x-1 = 34

169/2209 OR 7.22%
Step-by-step explanation:
[probability that both have the secret decoder ring]=(13/47)*(12/46)
[probability that both have the secret decoder ring]=(156/2162)
[probability that both have the secret decoder ring]=0.0722-------> 7.22%
the answer is 0.0722 (7.22%)
Answer:
6
Step-by-step explanation:
Luckily for us, the expression only contains a variable y, so we can disregard the values for variables x and w.
Note, that y = 1.
With that in mind, let's evaluate the expression by plugging the value of y into the expression.
11y - 5 = ?
11(1) - 5 = ?
11 - 5 = ?
6 = ?
Hence, our expression evaluated to 6 when y = 1.
Cheers.
Answer:
...
Step-by-step explanation:
I find it useful to use a graphing calculator to find the zeros of higher-order polynomials. Once you find one or more rational zeros, you can factor them out to find the reduced polynomial factors (or you can use synthetic division).
1. This factors as (5x+2)(3x-1)(x-8). Roots are {-2/5, 1/3, 8}
2. This factors as (x-9)(x²-5x+2). Roots are {2.5-√4.25, 2.5+√4.25, 9}
3. This factors as (x-6)(5x²+3x+1). Roots are{-0.3-i√0.11, -0.3+i√0.11, 6}
