Answer:

Step-by-step explanation:

x^2-9x=-2  move the -2 over and set to 0

x^2-9x+2=0  

This can not be factored, so use the quadratic formula.

x=9±√73 /2

Answer:

x = 9 + sqrt(73) / 2

x = 9 - sqrt(73) / 2

Step-by-step explanation:

Assuming you want to factor and find its roots:

[Put all the terms in the left hand size]

x^2-9x+2=0

[Use the quadratic formula; Not factorable and too tedious for completing the square]

x = -b +- sqrt(b^2-4ac) / 2a

x = 9 + sqrt(9^2 - 4(1)(2)) / 2(1)

x = 9 - sqrt(9^2 - 4(1)(2)) / 2(1)

x = 9 + sqrt(73) / 2

x = 9 - sqrt(73) / 2

Answer:

  (7 -24√3)/50 = 0.14 -0.48√3

Step-by-step explanation:

Sine is negative and cosine is positive in the 4th quadrant, so ...

  sin(α) = -√(1 -cos(α)²) = -√(1 -576/625) = -7/25

Then the cosine of the angle sum is ...

  cos(α +5π/6) = cos(α)cos(5π/6) -sin(α)sin(5π/6)

  = (24/25)(-√3/2) -(-7/25)(1/2)

  = (7 -24√3)/50 = 0.14 -0.48√3

Answer:

Lower

Step-by-step explanation:

Use the number 100 to see how the value changes:

First, calculate the 60% drop:

100(0.4)

= 40

Then, calculate the 75% increase:

40(1.75)

= 70

So, since 70 is smaller than 100, the value is lower than where it started.

Step-by-step explanation:

Step 1: Define

5x - 3 = 5

Step 2: Solve for x

We need to add 3 to both sides of the equation to isolate the x term and to equalize the equation.

Answer:

u + v = 2

Step-by-step explanation:

If v = 1 - i

and u = 1 + i

Then we have to calculate and value of u + v

Now u + v = ( 1 - i ) + ( 1 + i )

               = (-i + i) + ( 1 + 1 )    [by adding like terms]

               =  0 + 2

               = 2

= u + v = 2

Answer:

Option 3: 14 is the correct answer.

Step-by-step explanation:

Slope is denoted by m and is calculated using the formula:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

Here

(x1,y1) are the coordinates of first point and

(x2,y2) are the coordinates of second point

Given

(x1,y1) = (3, -20) and

(x2,y2) = (5,8)

Putting the values in the formula, we get

[tex]m = \frac{8-(-20)}{5-3}\\m = \frac{8+20}{2}\\m = \frac{28}{2}\\m = 14[/tex]

The slope of line passing through points (3, -20) and (5,8) is 14.

Hence,

Option 3: 14 is the correct answer.

Answer:

[tex]x=-5[/tex]

Step-by-step explanation:

STEP 1: Simplify each term.

[tex]x^2+10x+20=-5[/tex]

STEP 2: Move 5 to the left side of the equation by adding it to both sides.

[tex]x^2+10x+20+5=0[/tex]

STEP 3: Add 20 and 5.

[tex]x^2+10x+25=0[/tex]

STEP 4: Factor using the perfect square rule.

[tex](x+5)^2=0[/tex]

STEP 5: Set the x+5 equal to 0.

[tex]x+5=0[/tex]

STEP 6: Subtract 5 from both sides of the equation.

[tex]x=-5[/tex]

Answer:

x = 6

Step-by-step explanation:

To solve this equation, we need to isolate x. To do that, we need to divide both sides of the equation by 0.5. That gives us:

0.5x=3

x=3/0.5 = 6

Answer:

x=6

Step-by-step explanation:

0.5x÷0.5=3÷0.5

x=3÷0.5

Step-by-step explanation:

Answer:

0

Step-by-step explanation:

We can find the slope using

m = ( y2-y1)/(x2-x1)  where ( x1,y1) and ( x2,y2) are points on the line

m = ( -2 - -2)/(8 - 2)

    = ( -2 +2) / ( 8-2)

    = 0/6

   =0

The slope is 0

Answer:

n=8

Step-by-step explanation:

3n=−8+4n

Simplify both sides of the equation.

3n=4n−8   (there isn't so It stays the same.

Subtract 4n from both sides.

3n−4n=4n−8−4n

−n=−8

Divide both sides by -1.

−n/-1 =−8/-1

Answer:

A. 55

Step-by-step explanation:

The direct distance from Las Palmas to Lowell = the altitude or height of the right triangle.

According to the right triangle altitude theorem, thus:

[tex] h = \sqrt{xy} [/tex]

Where,

h = direct distance from Las Palmas to Lowell = ?

x = direct distance from Trevino to Lowell = 100 miles

y = direct distance from Lowell to Sun City = 30 miles

Plug in the values into the equation

[tex] h = \sqrt{100*30} [/tex]

[tex] h = \sqrt{3,000} [/tex]

[tex] h = 55 miles [/tex] (nearest mile)

Answer:

27-18 = 9, baby grew 9 inches

Step-by-step explanation:

The length of the baby will increase 0.9 inch per month.

Given is that a baby is 18in long at birth and 27in long in ten months

At birth, the length of baby = 18 inches.

After 10 months, the length of the baby = 27 inches.

Increase in length per month will be -

r = (27 - 18)/(10 - 0)

r = 9/10

r = 0.9 inch

Therefore, the length of the baby will increase 0.9 inch per month.

9x^4-36x^3-27x^2

Step-by-step explanation:

assuming those are exponents

Answer:

9x^4 - 36x^3 - 27x^2

Step-by-step explanation:

9x(x^3 - 4x^2 - 3x)

Multiply 9x to each of the terms in the parentheses:

9x^4 - 36x^3 - 27x^2

x^2 + 5x + 6 factors out to be (x + 2)(x + 3).

14x + 42 factors out to be 14(x + 3).

Answer:

26183

Step-by-step explanation:

Given that,

The population of the city of Gary is 75,282. 34.78% of Gary residents have a higher education degree.

We need to find the no of people in Gary have a higher education degree. It can be simply calcualted by taking 34.78% of 75,282 as follows :

[tex]P=75282\times 34.78\%\\\\ =75282\times \dfrac{34.78}{100}\\\\=26183.07[/tex]

or

P = 26183

So, there are 26183 people in Gary have a higher education degree.

Answer:

common ratio is 2/5

First term is  125/2

The sum of the first n terms is: [tex]S_n=\frac{125}{2} \, \frac{1-(2/5)^n}{3/5}[/tex]

The infinite sum is: [tex]S_\infty =\frac{625}{6}[/tex]

Step-by-step explanation:

The 4th term is 4, and the seventh term is 32/125 so we use the definition of nth term of a geometric sequence to create the following two equations:

[tex]a_4=a_1\,*\,r^{4-1} = a_1\,*\,r^3\\4=a_1\,*\,r^3\\and\\a_7=a_1\,*\,r^{7-1} = a_1\,*\,r^6\\\frac{32}{125} = a_1\,*\,r^6[/tex]

Now we divide a7 by a4 to get rid of a1 and work on determining the common ratio of the sequence:

[tex]\frac{a_7}{a_4} =\frac{8}{125} =\frac{a_1\,r^6}{a_1\,r^3} =r^3\\then\\r=\sqrt[3]{\frac{8}{125} } =\frac{2}{5}[/tex]

So, the common ratio is 2/5

we can now determine the first term:

[tex]a_4=4=a_1\,*\,(2/5)^3\\a_1=\frac{125*4}{8} =\frac{125}{2}[/tex]

The sum of the first n terms is given by the formula:

[tex]S_n=\frac{125}{2} \, \frac{1-(2/5)^n}{1-(2/5)} \\S_n=\frac{125}{2} \, \frac{1-(2/5)^n}{3/5}[/tex]

and therefore, the infinite sum is:

[tex]S_\infty = a_1\,\frac{1}{1-r} = \frac{125}{2} \,\frac{5}{3} =\frac{625}{6}[/tex]
