Step-by-step explanation:

This polynomial has like terms that can further be simplified

2 - 11x^2 + 6x^2- 8x

2 - 5x^2 - 8x

multiply by negative to take 2 to the right.

-(2 - 5x^2 - 8x)

= 5x^2 + 8x - 2

It's named a Second Degree Polynomial because the highest degree(exponent) of x in the final solution is 2.

it has 3 terms : 5x^2 , 8x , 2

Answer:

TU = 15

Step-by-step explanation:

The two rectangles are similar. That means that the lengths of  corresponding sides are in the same ratio.

Pairs of corresponding sides:

MN, ST

NO, TU

OP, UV

PM, VS

Equal ratios of lengths of corresponding sides:

MN/ST = NO/TU = OP/UV = PM/VS

Plug in the given information:

MN/ST = 10/x = 4/6 = PM/VS

10/x = 4/6

4x = 10 × 6

4x = 60

x = 15

TU = 15

Divide 12 by 3 to determine Catherine's age.

[tex]12 \div 3 = 4[/tex]

Catherine is 4 years old when Cisca is 12 years old.

Let's identify when Cisca will be twice as old as Catherine by representing the ages per future years.

Year 1: 13, 5

Year 2: 14, 6

Year 3: 15, 7

Year 4: 16, 8

Year 5: 17, 9

Year 6: 18, 10

In 4 years, Cisca will be twice as old as Catherine.

Her age is 16.

She would be 4 years

Age of Catherine = X

Age of Cisca = 12yrs = 3x

Therefore X = 12/3= 4 years.

Actual age of Catherine = 4 years.

Twice ( 2x) age of Catherine = 2×4= 8

Therefore, she will be 4 years to be twice as old as Catherine

Answer:

x = 3, x = 1

The points at which the curve crosses the x-axis are (3, 0) and (1, 0)

Step-by-step explanation:

Quadratic formula:

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]

Quadratic equation: [tex]ax^2+bx+c[/tex]

Therefore, for   [tex]x^2-4x+3[/tex]:

a = 1   b = -4   c = 3

Inputting values into quadratic formula:

      [tex]x=\dfrac{4\pm\sqrt{(-4)^2-(4\times1\times3)} }{2\times1}[/tex]

[tex]\implies x=\dfrac{4\pm\sqrt{16-12} }{2}[/tex]

[tex]\implies x=\dfrac{4\pm\sqrt{4} }{2}[/tex]

[tex]\implies x=\dfrac{4\pm2 }{2}[/tex]

[tex]\implies x=2\pm1[/tex]

[tex]\implies x=3, x=1[/tex]

Therefore, the points at which the curve crosses the x-axis are (3, 0) and (1, 0)

On solving the provided question, we can say that Cai's thinking expression will be area of the poster k = Ax Bt +Cz => K = x² + lb + 1/2wm

An expression is combination of variables, numbers and operators.

Cai's thinking expression will be.

The three sections are of different shapes which includes a square, rectangle and a triangle.

The area of square is side times of side= x²

The area of rectangle is length times of breadth (lb)

The area of triangle=1/2length times of breadth(1/2lb)

Area of the poster k = Ax+By+Cz

Ax = x²

Bx = lb

Cz = 1/2wm

K = x² + lb + 1/2wm

Hence, Cai's thinking expression will be area of the poster K = x² + lb +1/2wm

Step-by-step explanation:

At x =0 y is 14. The pattern of y is 14 greater than x continues.

Answer:

y=x+14

Step-by-step explanation:

Each of the x numbers are being added to 14 to get the y number.

Let us check if this is the answer:

the first numbers in the table are 0 and 14

0 plus 14 equals 14.

Using the vertex of a quadratic function, it is found that Phoenix received the highest amount of precipitation on the month of May.

A quadratic equation is modeled by:

[tex]y = ax^2 + bx + c[/tex]

The vertex is given by:

[tex](x_v, y_v)[/tex]

In which:

[tex]x_v = -\frac{b}{2a}[/tex]

[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]

Considering the coefficient a, we have that:

In this problem, the precipitation each month x in Phoenix is given by:

[tex]y = -0.04088x^2 + 0.4485x + 1.862[/tex]

Hence the coefficients are a = -0.04088, b = 0.4485, c = 1.862, and the month for which the precipitation will be highest is given by:

[tex]x_v = -\frac{0.4485}{2(-0.04088)} = 5.48[/tex]

Hence during the month of May.

Answer:

She needs to dance about 154 hours.

Step-by-step explanation:

$1,000 minus $75 is $925.

$925 divided by $6 is about 154 hours.

========================================================

Work Shown:

[tex]\frac{2\sqrt{72}}{\sqrt{8}+\sqrt{2}}\\\\\frac{2\sqrt{36*2}}{\sqrt{4*2}+\sqrt{2}}\\\\\frac{2\sqrt{36}*\sqrt{2}}{\sqrt{4}*\sqrt{2}+\sqrt{2}}\\\\\frac{2*6*\sqrt{2}}{2*\sqrt{2}+\sqrt{2}}\\\\\frac{12\sqrt{2}}{2\sqrt{2}+\sqrt{2}}\\\\\frac{12\sqrt{2}}{3\sqrt{2}}\\\\\frac{12}{3}\\\\4[/tex]

Note in step 2, I factored each number in the square root to pull out the largest perfect square factor. From there, I used the rule that [tex]\sqrt{A*B} = \sqrt{A}*\sqrt{B}[/tex] to break up the roots.

Answer:

4

Step-by-step explanation:

We first simplify $\sqrt{72}$ and $\sqrt{8}$:\begin{align*}

\sqrt{72} &=\sqrt{36\cdot 2} = \sqrt{36}\cdot \sqrt{2} = 6\sqrt{2},\\

\sqrt{8} &= \sqrt{4\cdot 2} = \sqrt{4}\cdot \sqrt{2} = 2\sqrt{2}.

\end{align*}Then, we have

\[\dfrac{2\sqrt{72}}{\sqrt{8}+\sqrt{2}} = \dfrac{2\left(6\sqrt{2}\right)}{2\sqrt{2} + \sqrt{2}}

= \dfrac{12\sqrt{2}}{3\sqrt{2}} = \dfrac{12}{3}\cdot \dfrac{\sqrt{2}}{\sqrt{2}} = \boxed{4}.\]

The number of years it would take the money to double is 86.6 years.

Number of years =  (In fv / pv) / r

Answer:

Let x thousand births per day

Let y thousand deaths per day

Each day, the number of births in the world is 45 thousand less than three times the number of

deaths.

x=3y-45 (1)

Population increase= birth - death

=x-y(2)

substitute (1) into (2)

3y-45-y=241

2y-45=241

2y=196 (plus 45 from both side)

y=98 (divide 2 from both side)

x-y=241

x-98=241

x=339 ( pluse 98 from both side)

So, There are 339 thousand births per day

There are 98 thousand deaths per day

Answer:

0.68 : 0.32

Step-by-step explanation:

the probability of all the outcomes of an event is always 1 .

if P(E) = 0.32,

P(E') = 1 - 0.32

= 0.68

N.B that P(E') is the same as P( not E ).

since your answer should be given in the ratio form, as the odds against E ( probability not E : probability E),

P(E') : P(E)

0.68 : 0.32

Answer:

π/4, or 3π/4

Step-by-step explanation:

dy/dx = cos(x)*cos(x)+sin(x)*[-sin(x)]=(cosx)^2-(sinx)^2=[1-(sinx)^2]-(sinx)^2 = 1-2(sinx)^2

Tangent line is horizontal, so dy/dx = 0

1-2(sinx)^2 = 0

(sinx)^2 = 1/2

sinx = [tex]\frac{1}{\sqrt{2}}, -\frac{1}{\sqrt{2}}[/tex]

Between 0 and pi, sinx >0

so sinx = [tex]\frac{1}{\sqrt{2}}[/tex]
