It's all about matching patterns.

The coefficient of "a" in the given sequence is the term number (1, 2, 3, ...) and the constant remains constant at 1. Thus the 15th term can be expected to be ...
c. 15a + 1

Answer:

Q(-10) = 299

Step-by-step explanation:

$Q(x) = 3x^{2} - 1$ $Q(-10) = 3(-10)^{2} - 1$

$Q(-10) = 3(100) - 1$ (-10 to the second power is 100 (negative times a negative equals a positive)

$Q(-10) = 300 - 1$ 3 times 100 equal 300

$Q(-10) = 299$

What is 1/3 of 30% of 5/6 of 0.6 of 12?

aliina [53]

Step-by-step explanation:

$\frac{1}{3 } \times \frac{30}{1} = 10 \\ \\ \frac{10}{1} \times \frac{5}{6} = 8.33 \\ \\ \frac{833}{100} \times \frac{6}{10} = 4.998 \\ \\ \frac{4998}{1000} \times \frac{12}{1} = 59.976$
