Convert degrees to radians, multiply by π/180° , since a full circle is 360 ° 360 or 2π radians.
− 405°⋅ π /180° radians
Cancel the common factor of 45 .
-9 ⋅ π/4 radians
Combine −9 and π/4
-9π/4
Move the negative in front of the fraction.
-9π/4 radians
Answer:
858 the next one is 947
Step-by-step explanation:
I hope it's right bye
X=3, y=3
Solve the following system:
{4 x + 2 y = 18 | (equation 1)
2 x + 3 y = 15 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{4 x + 2 y = 18 | (equation 1)
0 x+2 y = 6 | (equation 2)
Divide equation 1 by 2:
{2 x + y = 9 | (equation 1)
0 x+2 y = 6 | (equation 2)
Divide equation 2 by 2:
{2 x + y = 9 | (equation 1)
0 x+y = 3 | (equation 2)
Subtract equation 2 from equation 1:
{2 x+0 y = 6 | (equation 1)
0 x+y = 3 | (equation 2)
Divide equation 1 by 2:{x+0 y = 3 | (equation 1)
0 x+y = 3 | (equation 2)
Collect results:Answer: {x = 3
y = 3
Y = 2x - 3
y = -x+ 9
2x-3 = -x+9
2x+x = 9+2
3x = 12
x = 12/3
x = 4
y = 2(4)-3
y = 8-3 = 5
Mark on (4,5) & draw the line from origin.

Answer:
2450 times per minute (if my math is correct)
Step-by-step explanation:
A hummingbird should flap it's wings 2100 times in 30 seconds and 350 times in 5 seconds if you use a table. 2100+350=2450
