Answer:
(1) Conjugate = -i8
(2) Conjugate = -i3+9
(3) Conjugate = i2+1
(4) Conjugate = -3-iy
Step-by-step explanation:
From the question,
Conjugate of a surd is formed by changing the sign between a rational number and a surd in an expression.
The conjugate of a surd is obtained by changing the sign of the surd in the expression.
Given
(1) i3+i5 = i8
Conjugate is -i8
(2) i3+9
Conjugate is -i3+9
(3) -i2+1
Conjugate is i2+1
(4) -3+iy
Conjugate is -3-iy
Answer:
More expensive
Step-by-step explanation:
FIRST WASHING MACHINE PRICE - $360
SECOND WASHING MACHINE PRICE - MUST NOT BE CHEAPER
$720 x 30% = $216
The additional percentage must make the washing machine more expensive than the first one.
Answer:
110
Step-by-step explanation:
There is a theorem that says "The measure of an angle formed by a secant and a tangent drawn from a point outside the circle is HALF the difference of the intercepted arcs "
Hence we can say:
We can say:
Also, we know that circle's degree measure is 360, thus we can say:
To find Arc AB, we can use the two equations and add, thus we get:
Thus, arc AB = 360 - 250 = 110
