Solving the equation [tex]3r^2-2r=-9[/tex] using quadratic formula we get: [tex]\mathbf{ r=\frac{1+\sqrt{26}\:i}{3}\:or\: r=\frac{1-\sqrt{26}\:i}{3}}[/tex]

Step-by-step explanation:

We need to solve the equation [tex]3r^2-2r=-9[/tex] using quadratic formula.

The quadratic formula is: [tex]r=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

For the given equation: [tex]3r^2-2r=-9[/tex]

We can write it as: [tex]3r^2-2r+9=0[/tex]

We have a = 3, b= -2 and c=9

Putting values in quadratic formula and finding value of r

[tex]r=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\r=\frac{-(-2)\pm\sqrt{(-2)^2-4(3)(9)}}{2(3)}\\r=\frac{2\pm\sqrt{4-108}}{6}\\r=\frac{2\pm\sqrt{-104}}{6}\\We\:know\:that: \sqrt{-1}=i\\ r=\frac{2\pm\sqrt{26} \:i}{6}\\ r=\frac{2+2\sqrt{26}\:i}{6}\:or\: r=\frac{2-2\sqrt{26}\:i}{6}\\ r=\frac{2(1+\sqrt{26}\:i)}{6}\:or\: r=\frac{2(1-\sqrt{26}\:i)}{6}\\ r=\frac{1+\sqrt{26}\:i}{3}\:or\: r=\frac{1-\sqrt{26}\:i}{3}[/tex]

So, solving the equation [tex]3r^2-2r=-9[/tex] using quadratic formula we get: [tex]\mathbf{ r=\frac{1+\sqrt{26}\:i}{3}\:or\: r=\frac{1-\sqrt{26}\:i}{3}}[/tex]

Answer:

x = [tex]\frac{12}{5}[/tex]

Step-by-step explanation:

Given

2 = [tex]\frac{1}{2}[/tex] (5x - 8) ( multiply both sides by 2 to clear the fraction )

4 = 5x - 8 ( add 8 to both sides )

12 = 5x ( divide both sides by 5 )

[tex]\frac{12}{5}[/tex] = x

Answer:

The measure of angle x° = 34°.

Step-by-step explanation:

It is given that a

We know that side of the triangle below has been extended to form an exterior angle of 146°.

We know that a straight line makes a straight angle of 180°.

Thus,

The sum of x° and 146° must be 180°.

x° + 146° = 180°

subtract 146° from both sides

x° + 146° -  146°  = 180° - 146°

x° = 34°

Therefore, the measure of angle x° = 34°.

Step-by-step explanation:

Answer:

x = -17

Step-by-step explanation:

11 - 2x = 45

We first want to subtract 11 from both sides, so that we have the variable and it's factor on its own side. Making the equation:

-2x = 34

Next, we are going to divide each side by the variables' factor, which in this case is -2. However, there is a slightly longer way to do this, but when you're doing it by hand, it is much easier. I will be showing that way below.

So, instead of dividing either side by -2, we are going to divide both sides by 2. Giving us:

-x = 17

This next step is easy peasy. Since the negative is on the variables side and we need the variable to be positive, we just switch the position of the negative to the numerical side. Shown below.

-x = 17

to

x = -17

So, our final answer is x = -17

Hope this helps!

Answer:

Step-by-step explanation:

Solution

11 - 2x = 45

or, 2x=11-45

or, 2x=-34

x=-17

The solution is: 2/3 - 1/2  is reduced to its lowest terms of 8/12-4/8.

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

given that,

8/12-4/8

now, we have to reduced to its lowest terms.

so, we have,

8/12 to get the reduced form , we have to divide both side by 4,

we get, 8/12 = 2/3

similarly, 4/8 = 1/2

so, we get,

8/12-4/8

=2/3 - 1/2

= reduced to its lowest terms

Hence, 2/3 - 1/2  is reduced to its lowest terms of 8/12-4/8.

Answer:

503.8

Step-by-step explanation:

Since the hundredths place is above 4, you round up.

Answer:

503.8

Step-by-step explanation:

Note the tenth place value.

5 (hundreds place value)

0 (tens place value)

3 (ones place value)

.

7 (tenths place value)

8 (hundredths place value)

2 (thousandths place value)

You are trying to solve for the tenths place value. In this case, locate the tenths place value. The value is a 7. Now look at the place value directly next to it (hundredths place value). It is a 8. Because 8 is greater than 4, round up.

503.782 rounded to the nearest tenths is 503.8

Note:

Note the rules of rounding. IF:

The number is 4 or less, round down.

The number is 5 or greater, round up.

Answer:

Nickel = 13

Dimes = 8

Quarters = 16

Step-by-step explanation:

Let N denote Nickel,

Let D denote dime

Let Q denote quarter

Now, from online conversions;

1 nickel = 5 cents

Also, 1 dime = 10 cents

Also, 1 quarter = 25 cents

Isabelle has $5.45 which is also 545 cents.

Thus, we have;

5N + 10D + 25Q = 545 - - - (eq 1)

We are told that;

she has five more nickels than dimes, and twice as many quarters than dimes.

Thus;

N = D + 5

Also, Q = 2D

Plugging them for N and Q in eq 1 givens;

5(D +5) + 10D + 25(2D) = 545

5D + 25 + 10D + 50D = 545

25 + 65D = 545

65D = 545 - 25

65D = 520

D = 520/65

D = 8

Thus; N = D + 5 = 8 + 5 = 13

Q = 2D = 2 × 8 = 16

Step-by-step explanation:

Typical length of a termite is 1/2 inch

[tex]Lenght \ seen \ through\ magnifying\ glass=\frac{1}{2}(6) =3[/tex]

The length of the image of the termite seen through the magnifying glass is 3 inches.

A convex lens is used in a magnifying glass to provide an enlarged image of an object. Typically, the lens is fixed inside of a frame with a grip. You can use a magnifying glass to focus light, for example, to concentrate the sun's radiation and create a hot spot at the centre to start a fire.

Given that you are using a magnifying glass that shows the image of an object that is six times the object's actual size.

The length of the image of the termite seen through the magnifying glass will be calculated as,

Length = (1 / 2 ) x 6

Length = 3 inches

Therefore, the length of the image of the termite seen through the magnifying glass is 3 inches.

Answer:

E = 15 +16 = 31

6 males like cats ( the middle section) so C = 6

d = 6 +16 = 22

a = 19-6 = 13

b = 50-22 = 28

so in order: a = 13, b = 28, c = 6, d = 22, e = 31

Step-by-step explanation:

The required value for each variable in the two-way table is given as, a = 13, b = 28, c = 6, d = 22, and e = 31.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

From the table,

e = 15 + 16 = 31

At the middle of the table, c = 6 {6 males like cats}

d = 6 + 16 = 22

a = 19 - 6 = 13

b = 50 - 22 = 28

Thus, the required value for each variable in the two-way table is given as, a = 13, b = 28, c = 6, d = 22, and e = 31.
