Answer:
(3.5, 4)
Step-by-step explanation:
add and then divide (x1+x2 / 2, y1 + y2 / 2) so [(1+6)/2, (3+5)/2], so (3.5, 4)
Answer: A
Step-by-step explanation:
The first square is 22 inches on a side.
The second is 17.6 inches on a side
the third is 14.08 inches on a side.
We can suppose that we have a constant rate of decrease betwen the sides cubes, this means that:
22in*x = 17.6in
where x is the rate of scale.
x = 17.6/22 = 0.8
Now we test this with the second and third:
17.6in*0.8 = 14.08in
Ok, this works.
then the side of n-th cube can be found with the equation
L = 22*0.8^(n-1)
we can try the different options and see which one gives a value smaller than 10.
A) n = 5
L = 22*0.8^4 = 9.01
Then the correct option is A
Answer:
Final answer is
which is the last choice.
Step-by-step explanation:
In triangle ABC, we have been given a = 15, b = 11, and angle C is a right angle.
Now using those values, we need to find the exact value of cos B.
Apply Pythagorean formula:





Now apply formula of cos


Hence final answer is 
Step-by-step explanation:
when you solve it you will get an answer for it. so first solve the regular equation then the other two and then you have to add it all together to get another equation
