The answer would be 70 degrees.
In order to find this answer, we must first look at the cos value of an angle. The unknown angle here gives us an adjacent side of 3.4 and a hypotenuse of 10. Thus, we can use the following with cos.
Cos(A) = 3.4/10 or Cos(A) = .34
As a result, we can then use the arccos function to find the answer.
acrcos(.34) = A
70.12 = A
Then when we round, we'd get 70.
Answer:
<h2>D. Quadrant III</h2>
Step-by-step explanation:
Quadrant in coordinate geometry is divided into four parts which is called Quadrants.
Quadrants I (x, y)
Quadrants II (-x, y)
Quadrants III (-x, -y)
Quadrants IV (x, -y)
so W(-3, -9) both are negatives so its lie on Quadrants III
Diameter of the dartboard as given in the question = 18 inches
Then
Radius of the dartboard will be = 18/2 inches
= 9 inches
We already know that
Circumference of a circle = <span>2π</span>r
We also know that the value of <span>π = 3.14159
Then
Circumference of the dartboard = 2 * 3.14159 * 9 inches
= 56.548 inches
= 56.55 inches
So the radius of the dartboard is 9 inches and the circumference of the dartboard is 56.55 inches. I hope the procedure is absolutely clear to you.

Answer:
Step-by-step explanation:
Suppose that at time 
we have x mold cells. We are told that after 12 minutes the amount present is double. That is a 
we have 2x cells. Then, at 
we have (2x)*2 = 4x. We can continue as follows
we have (4x)*2 = 8x.
we have (8x)*2 = 16x
(one hour later) we have (16x)*2 = 32x.
So after one hour from now we have 32x cells.
