Answer:

  d.  AB = 54

Step-by-step explanation:

The triangle is isosceles, so AB = AC.

  (4x +6) = (5x -6)

  12 = x . . . . . . . . . . . . add 6-4x to both sides

Then the length of AB is ...

  AB = 4x +6 = 4(12) +6 = 48 +6

  AB = 54

Answer:

angke R is 70

Step-by-step explanation:

opposite angle of a parallelogram are equal.

I.e. angle C = angle R = 70

Answer:

70

Step-by-step explanation:

In a parallelogram, (I) opposite angles are congruent.

(II) Adjacent angles are supplementary.

(III) Opposite sides are equal and parallel.

(Iv)  Diagonals bisect each other

Angle R and angle C are opposite angles as they don't share any  arm's(sides).

∠R = ∠C = 70

Answer:

[tex] \rm \displaystyle \theta = \{ {150}^{ \circ} , {240}^{ \circ} \}[/tex]

Step-by-step explanation:

we would like to solve the following equation:

[tex] \displaystyle 2 \sin( \theta) \tan( \theta) = - 3[/tex]

to do so we need to put the equation in term of a function of a angle therefore rewrite tanθ:

[tex] \displaystyle 2 \sin( \theta) \cdot \frac{ \sin( \theta) }{ \cos( \theta) } = - 3[/tex]

simplify multiplication:

[tex] \displaystyle \frac{ 2\sin^{2} ( \theta) }{ \cos( \theta) } = - 3[/tex]

cross multiplication:

[tex] \displaystyle 2\sin^{2} ( \theta) = - 3 \cos( \theta) [/tex]

isolate -3cosθ to left hand side and change its sign:

[tex] \displaystyle 2\sin^{2} ( \theta) + 3 \cos( \theta) = 0[/tex]

well we can rewrite sin²θ by applying Pythagorean theorem and that yields:

[tex] \rm \displaystyle 2(1 - \cos^{2} ( \theta)) + 3 \cos( \theta) = 0[/tex]

distribute:

[tex] \rm \displaystyle 2 - 2\cos^{2} ( \theta) + 3 \cos( \theta) = 0[/tex]

now notice that our equation ended up with a pattern and that is Quadratic thus by letting cosθ be x to transform the equation:

[tex] \rm \displaystyle 2 - 2 {x}^{2} + 3 x = 0[/tex]

rearrange it to standard form:

[tex] \rm \displaystyle - 2 {x}^{2} + 3 x + 2 = 0[/tex]

divide both sides by -1:

[tex] \rm \displaystyle 2 {x}^{2} - 3 x - 2 = 0[/tex]

well we can factor the quadratic to do so rewrite -3x as -4x+x:

[tex] \rm \displaystyle 2 {x}^{2} - 4 x + x - 2 = 0[/tex]

factor out 2x:

[tex] \rm \displaystyle 2x ({x}^{} - 2)+ x - 2 = 0[/tex]

factor out 1:

[tex] \rm \displaystyle 2x ({x}^{} - 2)+ 1(x - 2 ) = 0[/tex]

group:

[tex] \rm \displaystyle (2x + 1)(x - 2 ) = 0[/tex]

by Zero Product property we obtain:

[tex] \rm \displaystyle \begin{cases} 2x + 1 = 0\\ x - 2 = 0 \end{cases}[/tex]

cancel 1 from the first equation and add 2 to the e equation:

[tex] \rm \displaystyle \begin{cases} 2x = - 1\\ x = 2\end{cases}[/tex]

substitute back:

[tex] \rm \displaystyle \begin{cases} 2 \cos( \theta) = - 1\\ \cos( \theta) = 2\end{cases}[/tex]

since cosθ is only defined for the interval [1,-1] the second equation is false for any value of θ but we can still continue the first equation

[tex] \rm \displaystyle \begin{cases} 2 \cos( \theta) = - 1\\ \cos( \theta) \neq 2\end{cases}[/tex]

divide both sides by 2:

[tex] \rm \displaystyle \cos( \theta) = \frac{ - 1} {2}[/tex]

by unit circle we acquire:

[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} \\ \theta = {240}^{ \circ} \end{cases}[/tex]

add period of 2nπ:

[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} + 2n\pi\\ \theta = {240}^{ \circ} + 2n\pi \end{cases}[/tex]

for the interval [0,2π) θ is only defined when n is 0 Thus:

[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} + 2(0)\pi\\ \theta = {240}^{ \circ} + 2(0)\pi \end{cases}[/tex]

simplify:

[tex] \begin{cases} \rm \displaystyle \theta = {150}^{ \circ} \\ \theta = {240}^{ \circ} \end{cases}[/tex]

hence,

θ is equal to 150° and 240°

Answer:

9 pi

Step-by-step explanation:

First find the circumference of the circle

C =2 * pi *r

C = 2 * pi *9

C = 18 pi

This is a semicircle which is 1/2 of a circle

Take 1/2 of the circumference

1/2 C = 1/2 ( 18 pi)

1/2 C = 9 pi

Answer:

0.25

Step-by-step explanation:

Hope it helps, sense it’s centered around 0.25 then the parameter would be 0.25

To It’s centered around 0.25 then the parameter would be 0.25.

We have given,

Suppose that many large samples were taken from a population and the sample proportion centered around 0.25

We have to determine which of the given is most likely the population parameter.

A sample means from any distribution. We could have a left-skewed or a right-skewed distribution.

To It’s centered around 0.25 then the parameter would be 0.25

Therefore option A(0.25) is correct

To It’s centered around 0.25 then the parameter would be 0.25.

I apologize

Answer:

-1, -4

Step-by-step explanation:

x + y = -5

x×y = 4

=>

x = -5 - y

=> (-5 - y) × y = 4

-5y - y² = 4

y² + 5y + 4 = 0

the solution for a quadratic equation is

x = (-b ± sqrt(b² - 4ac))/(2a)

a = 1

b = 5

c = 4

x = (-5 ± sqrt(25 - 16))/2 = (-5 ± 3)/2

=> x = -2/2 = -1 or x = -8/2 = -4

=> y = 4/-1 = -4 or y = 4/-4 = -1

since the sequence in an addition and multiplication does not make any difference, the two numbers are simply -1 and -4

Answer:

i=3/4

Step-by-step explanation:

Assuming that we are treating "i" as a variable and not the constant "i":

12+2i-i=9i+6

12+i=9i+6

12=8i+6

6=8i

8i=6

i=6/8

i=3/4

Therefore, the equation has only one real solution which is i=3/4
