Since the Power is directly proportional to the velocity, their ratio
is constant.
<span>Therefore </span>
which is a proportion:
500 : 1000 = x : 1728
that can be easily solved:
x = (500×1728)/1000 = 864kW
The answer is 17 because 42+4 is 46 and 46 minus 29 is 17
Answer:
42 degrees
Step-by-step explanation:
48 and r are equal.
The box means right angle, or 90 degrees
180-90-48=42 degrees
Answer: h(4) = 7
Step-by-step explanation:
Given h(x)= 2x-1
Find h(4)
Solution:
Substitute x = 4 into the equation
h (4) = 2 (4) - 1
h (4) = 8 - 1
h (4) = 7
A triangle can only have at most one right angle.
Here's a proof that shows why this is so:
We know that the sum of all interior angles of a triangle must add up to 180.
Let's say the interior angles are A, B, and C
A + B + C = 180
Let's show that having two right angles is impossible
Let A = B = 90
90 + 90 + C = 180
180 + C = 180
Subtract 180 from both sides
C = 0
We cannot have an angle with 0 degrees in a triangle. Thus, it is impossible to have 2 right angles in a triangle.
Let's try to show that it's impossible to have 3 right angles
Let A = B = C = 90
90 + 90 + 90 = 180 ?
270 ≠ 180
Thus it's impossible to have 3 right angles as well.
Let's show that is possible to have 1 right angle
Let A = 90
90 + B + C = 180
Subtract both sides by 90
B + C = 90
There are values of B and C that will make this true. Thus, a triangle can have at most one right angle.
Have an awesome day! :)
