Answer:

17 Degrees Celsius

Step-by-step explanation:

If you like to <em>visualize </em>then recommend using a number line.

Or you can calculate it:

(Difference Temp) = (End Temp) - (Start Temp)

(Difference Temp) = (12) - (-5)

(Difference Temp) = 17

Sharon is conducting research on two species of birds at a bird sanctuary. The number of birds of species A is represented by th
e-lub [12.9K]

Answer: After 7 years the number of birds of species A and B are same. and the number of birds during that year will be 140.


Step-by-step explanation:

Given: Sharon is conducting research on two species of birds at a bird sanctuary.

The number of birds of species A is represented by the equation below,where S represents the number of birds, x years after beginning her research.

S=2^x+12

The number of birds of species B is represented by the equation below,where S represents the number of birds, x years after beginning her research.

S=15x+35

To plot the above function, first find points by which they are passing.

For species A, At x=0 , S=1+12=13

At x=2 , S=2+12=14

Similarly find more points and plot curve on graph.

For species A, At x=0 , S=0+35=35

At x=2 , S=15+35=50

Plot a line with the help of these two points.

Now, from the graph the intersection of curve (for A) and line (for B) is at (7,140) which tells that After 7 years the number of birds of species A and B are same. and the number of birds during that year will be 140.

Calculate the length of CD give your answer to 3 significant figures.
Westkost [7]

12.7  
Using the Pythagorean theorem, you can easily calculate the length of BC.
So: 
BC = sqrt(12^2 - 6^2) = sqrt(144 - 36) = sqrt(108) = 10.39230485  
Now consider triangle BCD. You know all three angles and one side. Using the law of sines you know that ratio of the sine of each angle over the opposite side is constant. So: 
BC/sin(55) = CD/sin(90) 
BC/sin(55) = CD/sin(90) 
sin(90)BC/sin(55) = CD 
1*BC/sin(55) = CD 
BC/sin(55) = CD 
10.39230485/0.819152044 = CD 
12.68666167 = CD 
12.7 = CD
