v = -20
you may replace v with -20 and simplify to vertiy the answer.
Answer:
The ratio for sin(X) is 
The ratio for cos(X) is 
Step-by-step explanation:
- The ratio of the sine of a right triangle is:
Since we need the ratio for angle X, 
. From the picture we can infer that the opposite side of X is 
. The hypotenuse (the side opposite to the right angle) is 12, so replacing the values:
- The ratio of the cosine is:
Similarly, , adjacent side = 5, and hypotenuse = 12, so
Answer:
10800
Step-by-step explanation:
The number of bacteria in a colony growing exponentially. At 4 pm yesterday the number of bacteria is 400.And at 6 pm yesterday it was 3600. How many bacteria in the colony at 7 pm?
Step-by-step explanation:
B = B₀ Kⁿ
At 4 pm yesterday the number of bacteria is 400
B₀ = 400
n = number of hrs
at 6 pm yesterday it was 3600 => n = 6- 4 = 2 hrs
B₂ = 3600
=> 3600 = 400 * k²
=> k² = 9
=> k = 3
At 7 Pm Yesterday
n = 7-4 = 3
B₃ = 400 * 3³
=> B₃ = 27 * 400
=> B₃ = 10800
bacteria in the colony at 7 pm = 10800
or B₂ = 3600 & n = 7-6 = 1
Then B₃ = 3600 * 3¹ = 10800
And boom here
