<span>2, 4, 8, 16, –32, 64, …
Common ratio = 4/2 = 2
16/8 = 2
But -32/16 = -2.
The ratio is not constant, hence it is not a geometric.
D. The sequence is not a geometric sequence.</span>
Answer:
4^ (r-s)
Step-by-step explanation:
When the bases are the same, and we are dividing, we subtract the exponents
x^a ÷ x^b = x^ (a-b)
4^r ÷ 4^s = 4^ (r-s)
Answer:
72x^7+24x^3 (finding the derivative using the chain and power rules)

Answer:
Haeather ran at a speed of 5 miles per hour.
Step-by-step explanation:
Given that last week at the park Haeather ran 4 miles in 48 minutes, to determine what was Haeather rate of speed in miles per hour the following mathematical calculation must be performed:
48/4 = 12
Thus, Haeather ran 1 mile every 12 minutes.
60/12 = 5
1 x 5 = 5
Therefore, Haeather ran at a speed of 5 miles per hour.
Let's start his with some trigonometry
Cos60=x/30
X=15
Now we can use Pythagorean therom
15^2+b^2=30^2
B(y)= 25.98
