Answer:
x = 10.25
y = 6.7
Step-by-step explanation:
X = 8 - (-2.25) = 10.25
Y = 6 - 4.2 - (-4.9) = 6.7
Theo ran 3K in 9.6 minutes:
9.6 divided by 3 = 1.2 munutes
3 divided by 3 = 1k
1k = 1.2 minutes.
Estaban ran 5k in 13.5 minutes:
13.5 divided by 5 = 2.7 minutes
5 divided by 5 = 1k
1k = 2.7 munutes
Tetsuo ran 10k in 31.9 minutes:
31.9 divided by 10 = 3.19 munites
10 divided by 10 = 1k
1k = 3.19 minutes
Answer: Theo Ran the Fastest and all the writing above is the resoning.
Answer:
Expression Derivatives
y = tan-1(x / a) dy/dx = a / (a2 + x2)
y = cot-1(x / a) dy/dx = - a / (a2 + x2)
y = sec-1(x / a) dy/dx = a / (x (x2 - a2)1/2)
y = cosec-1(x / a) dy/dx = - a / (x (x2 - a2)1/2)
Answer:
a(n) = 7*2^(n - 1)
Step-by-step explanation:
The first term of the given geometric sequence, 7, 14, 28, 56, 112, ... , is 7, and the common ratio is 2. Each new term is twice the previous term.
Thus the general formula for the geometric sequence becomes
a(n) = 7*2^(n - 1).
As a check, let's see whether this formula correctly predicts the fourth term (56): Here n = 4, and so a(4) = 7*2^(4 - 1) = 7*2^3 = 7*8 = 56. Yes.
