Answer:

x^2 + 2x +1  = 2x + 2

Step-by-step explanation:

(x+1) = 2

multiplying both sides by x +1

(x +1) (x+1) = 2 (x+1)

x^2 + 2x +1  = 2x + 2

Answer:

x² + 2x + 1 = 2x + 2

Step-by-step explanation:

Multiply without the multiplication symbol so use distributive property.

(x+1)(x+1) = 2(x+1)

Use the FOIL method (first, outer, inner, last)

(x)(x)+(x)(1)+(1)(x)+(1)(1) = (2)(x)+(1)(2)

which will give you:

x²+x+x+1 = 2x+2

combine like terms

x²+2x+1 = 2x+2

ta da! hope this helps

The local operations manager for the Internal Revenue Service must decide whether to hire one, two, or three temporary tax exami
Helga [31]

Answer:

If she uses the Laplace criterion, the number of new examiners she will decide to hire is:

c. three

Step-by-step explanation:

a) Data:

Number of           Compliance

examiners     Low   Normal   High

One               50        50         50

Two              100        60         20

Three           150        70         -10

b) Outcome Calculations:

Number of                     Compliance

examiners            Low                      Normal                High

One              16.65 (50 *.333)     16.65 (50 *.333)     16.65 (50 *.333) =  50

Two              33.3 (100 *.333)      19.98 (60 *.333)      6.66 (20 *.333)  = 60

Three           49.95 (150 *.333)    23.31 (70 *.333)     -3.33 (-10 *.333) =  70

c) Decision:

Three has the highest payoff condition and is selected.

d) The Laplace criterion assumes that each compliance state is equally likely to happen.  Therefore, it assigns the same weight to each state of compliance.  Since there are three states of compliance, we shall assign each state a weight of 0.333.  The number of examiners that have the highest payoff condition is three, and therefore, the number "three" is selected.

Find an equation of the tangent line to the curve 2(x2+y2)2=25(x2−y2) (a lemniscate) at the point (−3,1). An equation of the tan
valina [46]

2(x^2+y^2)^2=25(x^2-y^2)

Let y=y(x), so that differentiating both sides wrt x gives

4(x^2+y^2)\left(2x+2y\dfrac{\mathrm dy}{\mathrm dx}\right)=25\left(2x-2y\dfrac{\mathrm dy}{\mathrm dx}\right)

If x=-3 and y=1, the above reduces to

40\left(-6+2\dfrac{\mathrm dy}{\mathrm dx}\right)=25\left(-6-2\dfrac{\mathrm dy}{\mathrm dx}\right)\implies\dfrac{\mathrm dy}{\mathrm dx}=\dfrac9{13}

This is the slope of the tangent line, which has equation

y-1=\dfrac9{13}(x+3)\implies\boxed{y=\dfrac{9x+40}{13}}
