Answer:
-625
Step-by-step explanation:
The magnitude gets raised to the power, and the angle gets multiplied by the power:
5(cis7pi/4)^4 = (5^4)cis(4·7π/4) = 625cis(7π) = 625cis(π) = -625
Answer:
-44 4/9
Step-by-step explanation:
-36 4/9-(-10 2/9)-(18 2/9)
-36 4/9+10 2/9 = 26 6/9
26 6/9 - (18 2/9)= -44 4/9
<span>The moving of decimal to the left is a shortcut to the
operation of multiplying number by decimal numbers. So the power of 10 that is involved
in converting the measurements of pete is -4, so he needs to multiply the
measurement by 10^-4 to convert it.</span>
Step-by-step explanation:
m∠2 = m∠4
y + 10 = 3y - 24
y - 3y = -24 - 10
-2y = -34
y = -34/-2
y = 17
m∠2 = y + 10
m∠2 = 17 + 10
m∠2 = 27°
Answer:
336 plants
Step-by-step explanation:
Area of a right triangle= 1/2•base•height
A= 1/2bh
A= 1/2•7•24
A= 84 yards^2
# of plants= yards^2•4
84•4= 336 plants
