1) 3r² – 2r=-9
Quadratic formula
Answer:
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]
What is 8/12-4/8 = reduced to its lowest terms

2/3-1/2
Step-by-step explanation:
#/#/$^%/£'fcjcutyfyi
The solution is: 2/3 - 1/2 is reduced to its lowest terms of 8/12-4/8.
What is division?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.

Round 503.782 to the nearest tenth.
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.

You are using a magnifying glass that shows the image of an object that is six times the object's actual size. Determine the length of the image of the termite seen through the magnifying glass.
Answer:
3 inches
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.
What is magnifying glass?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.
