Answer:

x = \sqrt{48} \\\\x = \sqrt{63} \\\\x = \sqrt[3]{73}

Step-by-step explanation:

x^2 = 48\\x^2 = 63\\x^3 = 73

Solve for x

Equation 1 ;

x^2 =48\\\\Square\:root\:both\:sides\\\\\sqrt{x^2} =\sqrt{48} \\\\Simplified \:form;\\x =4\sqrt{3}

Equation 2;

x^2 =63\\\\Square\:root\:both\:sides\\\\\sqrt{x^2} =\sqrt{63} \\\\Simplified \:form;\\x =3\sqrt{7}

Equation 3 ;

x^3 =73\\\\Cube\:root\:both\:sides\\\\\sqrt[3]{x^3}= \sqrt[3]{73}  \\\\x = \sqrt[3]{73}

Answer:

A, B, F

Step-by-step explanation:

To solve this, you look at the powers of x and take either the square root (if it is to a power of 2) or the cube root (if a power of 3) of both sides to isolate x. For the first equation, you take the square root of 48, so A is correct. For the second one, you take the square root of 63, so B is correct. For the final equation, you take the cube root of 73, so F is correct.

Expand and simplify (3x-4)(2x-1)(4x-3)​
aleksandrvk [35]

Answer:

24x³-62x²+49x-12

Step-by-step explanation:

We can start by multiplying the first two brackets together first.

(3x-4)(2x-1)(4x-3) = (6x²-3x-8x+4)(4x-3)

Evaluate like terms.

(6x²-3x-8x+4)(4x-3) = (6x²-11x+4)(4x-3)

Multiply the two brackets together.

(6x²-11x+4)(4x-3) = 24x³-18x²-44x²+33x+16x-12

Simplify.

24x³-18x²-44x²+33x+16x-12 = 24x³-62x²+49x-12

Tell me if you need it in factorised form.

The points A(-3, 2) and B(1,4) are vertices of an isosceles triangle ABC, where angle B = 90°
almond37 [142]

Answer:

Length of AB = 4.4721

Equation of line BC: y = -2x + 6

Step-by-step explanation:

To find the length of the line AB, we just need to find the distance between the points A and B.

We can find distance with the equation:

distance = \sqrt{(x_A - x_B)^2 + (y_A - y_B)^2}

distance = \sqrt{(-3 - 1)^2 + (2 - 4)^2}

distance = 4.4721

To find the equation of the line BC, first let's find the slope of the line AB.

This slope is given by:

m_{AB} = \frac{ y_A - y_B }{ x_A - x_B }

m_{AB} = \frac{ 2 - 4 }{ -3 - 1} = \frac{1}{2}

The line AB is perpendicular to the line BC (because mB = 90°), so the slope of line BC is:

m_{BC} = -\frac{1}{m_{AB}} = -2

so the line BC is:

y = -2x + b

To find the value of b, we can use the point B (1,4):

4 = -2 + b

b = 6

So we have:

y = -2x + 6

Find the mean, median, and mode(s) of the data. Choose the measure that best represents the data. Explain your reasoning. Find t
Kazeer [188]

Answer:

Mean: 17

Median: 16

Mode: 10

Step-by-step explanation:

8, 10, 10, 11, 16, 17, 19, 21, 41

Median: (the middle number in the number list/data set) 16

Mode: 10

Mean: 8 + 10 + 10 + 11 + 16 + 17 + 19 + 21 + 41 = 153/9 = 17
