Hey pls solve this question ​

Mathematics
1 answer:
Sholpan [36]3 years ago
6 0

Answer:

(13/2)^27

Step-by-step explanation:

First note that ( )^0 = 1, so we need not bother with the last term.

Next, note that

 (2/13)^(-6) divided by (2/13)^3 is (2/13)^(-9).

Finally, we must cube this last result.  We get:  (2/13)^(-9*3) = (2/13^(-27)

or

(13/2)^27

Note:  we're "evaluating" an algebraic expression here, not "solving it," since there is no equation here.

Answer: 77/95 chance

Step-by-step explanation: There are 8+7+6+5+4+3+2+1 = 36 choices that differ by 12 or more, so the probability they differ by 12 or more is 36/190 = 18/95. So the probability that they do not differ by 12 or more is 1 - 18/95 = 77/95. Brainliest please?

Which is an equation in point-slope form for the given point and slope? Point: (5, 9); Slope: 2
Ray Of Light [21]

(\stackrel{x_1}{5}~,~\stackrel{y_1}{9})~\hfill \stackrel{slope}{m}\implies 2 ~\hfill \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{9}=\stackrel{m}{2}(x-\stackrel{x_1}{5})

4x - 7 (2 - x) = 3x + 2
juin [17]

Answer:

x=2

Step-by-step explanation:

4x−7(2−x)=3x+2

4x+(−7)(2)+(−7)(−x)=3x+2(Distribute)

4x+−14+7x=3x+2

(4x+7x)+(−14)=3x+2(Combine Like Terms)

11x+−14=3x+2

11x−14=3x+2

Step 2: Subtract 3x from both sides.

11x−14−3x=3x+2−3x

8x−14=2

Step 3: Add 14 to both sides.

8x−14+14=2+14

8x=16

Step 4: Divide both sides by 8.

x=2

Find the radius of the circle if the center is at (1, 2) and the point (-3, 4) lies on the circle.
Anton [14]

Answer:

2√5

Step-by-step explanation:

The radius is the distance from the center to a point anywhere along the edge of the circle. To find the distance between these two points, use the distance formula.

d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2} \\d = \sqrt{(1--3)^2 + (2-4)^2}\\ d = \sqrt{4^2 + -2^2}\\ d = \sqrt{16 + 4}\\ d = \sqrt{20} \\d = 2\sqrt{5}
