Vertical angles equal eachother
set angle 4 and angle 8 equal to eachother
3x=x+40
-x both sides
2x=40
÷2 both sides
x=20
solve for angle 4
3 (20)
60 B
Answer: 25 inches
Step-by-step explanation:
Let's imagine that this line is the leg A______________B________C
x 11
|___________36____________|
From A to C = 36 inches
From B to C = 11 inches
To find A to B all we have to do is subtract the knee to ankle length (11) from total leg length (36), which 36 - 11 = 25 inches.
No. Of times bee beats in 1 sec=250
Average time =?
Frst find how many times bee beats in 1 min.
No. Of times bee beats in 1 min= 250*60=15000
Average time= 15000/ 250
Average time=60 times
The answer is choice D
-----------------------------------------
Explanation:
We can rule out choice B and choice C which are y = 2.4^x and y = 3.5^x respectively. Why can we eliminate these? Because they are growth functions (the bases are larger than 1). The graph shown is a decay function. It goes downhill as you read it from left to right.
The answer is either choice A or choice D
If we plug in x = -2 into the equations for A and D, we get
y = 0.65^x = 0.65^(-2) = 2.36686
y = 0.32^x = 0.32^(-2) = 9.765625
The result for choice D is much closer to what the graph is showing. The graph appears to have the point (-2,11) on the curve. So that's why choice D is the best answer.
Note: the graph is a bit small and its not entirely clear which points are on this graph other than (0,1). So this is a bit of educated guesswork.
