Answer:
z = -9.538546756+ 15.26486573i
Step-by-step explanation:
z = |z| cos theta + |z| i sin theta
We know |z| and theta
z = 18 cos 122 +18i sin 122
z = -9.538546756+ 15.26486573i
Answer:
30 cm.
Step-by-step explanation:
Draw a line from R perpendicular to PQ to meet PQ at T.
RQT forms a right-angled triangle with RT = SP = 15.
So tan 36.87 = RT / TQ
tan 36.87 = 15 / TQ
TQ = 15 / tan 36.87
= 20 cm.
Now PT = SR = 10, so
PQ = 10 + 20
= 30 cm.
Answer:
36 inches
Step-by-step explanation:
Given data
Area of triangle =2 1/4 square inches
Area =9/4 square inches
Height of triangle =1/8 inches
We know that the expression for the area of triangle is
Area = 1/2Base *Height
9/4=1/2*Base *1/8
9/4=Base/16
Cross multiply
16*9=Base*4
144=Base*4
Base =144/4
Base=36 inches
Answer:
y + 4 = 4(x-4)
Step-by-step explanation:
Use the point slope form of a line to write the equation by substituting m = 4 and the point (4,-4).
