Answer:

a) Everyone on the team talks until the entire team agrees on one decision.

Step-by-step explanation:

Option B consists of voting and not everyone would like the outcome. Option C is making an outsider the decision maker, which can't be helpful since he / she won't have as strong opinions as the team itself. Option D is just plain wrong as it defeats the purpose of team work and deciding as one team. So, I believe option A makes the most sense

I NEED HELP PLS THIS IS DUE IN 3 HOURS

Mariulka [41]

Answer:

Part 1) $x^{2} -2x-2=(x-1-\sqrt{3})(x-1+\sqrt{3})$

Part 2) $x^{2} -6x+4=(x-3-\sqrt{5})(x-3+\sqrt{5})$

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

Part 1)

in this problem we have

$x^{2} -2x-2=0$

so

$a=1\\b=-2\\c=-2$

substitute in the formula

$x=\frac{-(-2)(+/-)\sqrt{-2^{2}-4(1)(-2)}} {2(1)}\\\\x=\frac{2(+/-)\sqrt{12}} {2}\\\\x=\frac{2(+/-)2\sqrt{3}} {2}\\\\x_1=\frac{2(+)2\sqrt{3}} {2}=1+\sqrt{3}\\\\x_2=\frac{2(-)2\sqrt{3}} {2}=1-\sqrt{3}$

therefore

$x^{2} -2x-2=(x-(1+\sqrt{3}))(x-(1-\sqrt{3}))$

$x^{2} -2x-2=(x-1-\sqrt{3})(x-1+\sqrt{3})$

Part 2)

in this problem we have

$x^{2} -6x+4=0$

so

$a=1\\b=-6\\c=4$

substitute in the formula

$x=\frac{-(-6)(+/-)\sqrt{-6^{2}-4(1)(4)}} {2(1)}$

$x=\frac{6(+/-)\sqrt{20}} {2}$

$x=\frac{6(+/-)2\sqrt{5}} {2}$

$x_1=\frac{6(+)2\sqrt{5}}{2}=3+\sqrt{5}$

$x_2=\frac{6(-)2\sqrt{5}}{2}=3-\sqrt{5}$

therefore

$x^{2} -6x+4=(x-(3+\sqrt{5}))(x-(3-\sqrt{5}))$

$x^{2} -6x+4=(x-3-\sqrt{5})(x-3+\sqrt{5})$

Find the distance between the points (-1,-2) and (5,2). Simplified radical form.

frozen [14]

Answer:

2 $\sqrt{13}$

Step-by-step explanation:

Using the distance formula,

$\sqrt{( x_{2}-x_{1} )^2+(y_{2} -y_{1})^2 }$

We just need to plug in the numbers.

So $\sqrt{(-1-5)^2+(-2-2)^2}$

Then we simplify it to

$\sqrt{(-6)^2+(-4)^2} , to \sqrt{36+16}$

Finally, we get

$\sqrt{52}$ , which is $2\sqrt{13}$ when simplified.

Classify What type of number is the square root of 2

Amanda [17]

Answer:

The square root of 2, or the (1/2)th power of 2, written in mathematics as √2 or 21⁄2, is the positive algebraic number that, when multiplied by itself, equals the number 2. Technically, it is called the principal square root of 2, to distinguish it from the negative number with the same property

The triangle has an area of 7\frac{7}{8}7 8 7 cm2 and a base of 5\frac{1}{4}5 4 1 cm. What is the length of h? Explain your

motikmotik

Answer:

<h3>3cm</h3>

Step-by-step explanation:

Area of a triangle = 1/2 * base * height

Given

Area = 7 7/8cm²

Base = 5 1/4 cm

Required

Height of the triangle

Substitute;

7 7/8 = 1/2 * 5 1/4 * Height

63/8 = 1/2 * 21/4 * h

63/8 = 21H/8

63 = 21H

H = 63/21

H = 3cm

Hence the length of h is 3cm
