You need to provide the total points! Once you have the total test points, divide that number by 12

How do i isolate y in 4x - 2y = 22

Irina18 [472]

4x - 2y = 22

Start by adding 2y to both sides to cancel out the -2y

4x = 22 + 2y

Now you can divide by 4

x = 22/4 + 2y/4

Reduce all the fractions to get your answer, which is

$x = \frac{11}{2} + \frac{y}{2}$

-50 Points- If segment AC and segment BC are tangent to circle O, find the value of x.

Shkiper50 [21]

Answer:

x = 170 deg

Step-by-step explanation:

A tangent to a circle is perpendicular to the radius of the circle at the point of tangency. That means that in quadrilateral AOBC, angles A and B are right angles and measure 90 deg.

The sum of the measures of the angles of an n-sided polygon is

(n - 2)180 deg

In this case, n = 4, so

(4 - 2)180 deg = 360 deg

m<A + m<O + m<B + m<C = 360

90 + x + 90 + 10 = 360

x + 190 = 360

x = 170

Answer: 170 deg

Find the fourth roots of 256(cos 240° + i sin 240°).

Mashcka [7]

Answer with Step-by-step explanation:

We are given that

We have to find the fourth roots of given complex number.

$(256)^{\frac{1}{4}}=(4^4)^{\frac{1}{4}}=4^^{\frac{1}{4}\times 4}=4$

By using the formula

$(a^b)^x=a^{bx}$

$\theta=240^{\circ}$

$\theta=\frac{240}{4}=60^{\circ}$

Angle of rotation= $\frac{360}{4}=90^{\circ}$

Therefore, the four roots of given complex number are

$4(cos 60^{\circ}+i sin60^{\circ})$

$4(cos150^{\circ}+i sin150^{\circ})$

$4(cos240^{\circ}+isin 240^{\circ})$

$4(cos330^{\circ}+i sin330^{\circ})$
