divide (3x^3+5x) by (x+3)

Answers

Using synthetic division:

Draw an upside down division symbol. Place the constant of x + 3 (-3) on the outside, and the coefficients of 3x³ + 5x on the inside, like so:
   
    | x³   x²   x¹   x⁰
-3 | 3    0    5    0
    |      
    |___________

Bring down the first coefficient:

    | x³   x²   x¹   x⁰
-3 | 3    0    5    0
    |      
    |___________
      3

Multiply the number outside the symbol (-3) by the 3 you've just brought down. Place that number under the next coefficient to the right.

    | x³   x²   x¹   x⁰
-3 | 3    0    5    0
    |      -9
    |___________
      3

Add the new number (-9) to the coefficient above it and place that number directly underneath it.

    | x³   x²   x¹   x⁰
-3 | 3    0    5    0
    |      -9
    |___________
      3   -9

Repeat this process until you've reach the end of the symbol.

    | x³   x²   x¹   x⁰
-3 | 3    0    5    0
    |      -9   27 -96
    |___________
      3   -9  32  -96

The resulting numbers are coefficients, the first three of the quotient, and the last one of the remainder. The remainder is the last coefficient (-96) over the divisor.

(3x^3+5x) / (x+3) = 3² - 9x + 32 + -96 / x + 3

What is the surface area of a triangular prism with dimensions of 10m, 9m, 6m, and 8m?

Answers

Final answer:

The surface area of the triangular prism with dimensions of 10m, 9m, 6m, and 8m is 218m².

Explanation:

To find the surface area of a triangular prism, we need to find the sum of the areas of all its faces.

A triangular prism has two triangular bases and three rectangular lateral faces. Let's calculate the surface area:

1. The area of each triangular base can be found using the formula: 1/2 × base × height.

For the first base, the base is 10m and the height is 6m. So the area of the first base is 1/2 × 10m × 6m = 30m².

Similarly, for the second base, the base is 9m and the height is 8m.

So the area of the second base is 1/2 × 9m × 8m = 36m².

2. The area of each rectangular lateral face can be found using the formula: length × width.

The lengths of the lateral faces are 10m, 9m, and 6m.

The common width of the lateral faces is the height of the prism, which is 8m.

So the total area of the lateral faces is 10m × 8m + 9m × 8m + 6m × 8m = 152m².

3. Finally, the total surface area of the triangular prism is the sum of the areas of the bases and the lateral faces: 30m² + 36m² + 152m² = 218m².

Therefore the surface area of a triangular prism is 218m².

Use the parabola tool to graph the quadratic function. f(x)=2x2+12x+16

Answers

we have that
f(x)=2x²+12x+16

using a graph tool
see the attached figure

Answer:

Step-by-step explanation:

To obtain the graph of a parabola, three data are necessary: ​​the vertex (the vertex is the highest or lowest point of the graph corresponding to the parabola and there it is on the plane of symmetry of the parabola), the roots ( those values ​​of x for which the expression is 0. Graphically,  the roots correspond to the abscissa of the points where the parabola  cuts the x-axis.) and the concavity.

Being f(x)=ax²+bx+c, you can see that, in this case, a=2, b=12 and c=16. So:

Vertex= for your calculation, [tex]xv=\frac{-b}{2*a}=\frac{-12}{2*2}[/tex], so xv=-3. Now that you know x, all you have to do is enter its numerical value into the original formula to find yv. yv=2*(-3)²+12*(-3)+16. Then yv=-2Roots:  The roots are calculated using the expression: [tex]x1,x2=\frac{-b+-\sqrt{b^{2}-4*a*c } }{2*a}[/tex]. Replacing the values that you have:[tex]x1,x2=\frac{-12+-\sqrt{12^{2}-4*2*16 } }{2*2}[/tex] Solving, you obtain x1=-2 and x2=-4Concavity: If a> 0 (positive) the parabola is concave or pointed upwards, while if a <0 (negative) the parabola is convex or pointed downwards. In this case a = 2, so the parabola opens upward, being concave.

In this way, the graph shown in the attached image is obtained.

The wall measures 6 centimeters

90 meters is your answer for the width

hope this helps
So you know that 1cm = 15 m in the diagram, and the width of the diagram's building is 6 cm. To solve, first you have to convert the 15 m to cm (centimeters) to make the measurements equivalent. There are 100 cm in 1 m, so you will multiply 15 x 100 = 1,500. 
Now just multiply 6 x 1,500 to figure out how many cm the real wall is:
6 x 1,500 = 9,000     so the width of the real wall is 9,000 cm, but they want the answer in m (meters) so just divide 9,000 by 100:
9,000 ÷ 100 = 90     Your answer is 90 m. Hope this was helpful!

It’s Daice if you favtorize it will become 6^3 x1/4^4 then it becomes 6^3/4^2

We will be using division property of exponents.

The property is as follows:

[tex] \frac{x^{a}}{x^{b}} =x^{a-b} [/tex]

This means if we have same base in both numerator and denominator, the exponents will get subtracted.

In our question we have

[tex] \frac{4^{1}}{4^{3} } =4^{1-3} [/tex]

[tex] \frac{4^{1}}{4^{3} } =4^{-2} [/tex]

Now we will use another property of exponents here:

A container holds 8 gallons of water. If 4 5 of a gallon is added to the container each hour, how many hours would it take to fill the container?

Answers

So we know that 4.5 x 2 = 9, so it wouldn't work.
And because it wouldn't work it wouldn't take 2 hours.

4.5 = 1 hour and 9 = 2.

So we'll have to divide 4.5 by 2 by first turning it into a fraction.

4.5 = 4 1/2
4 1/2 ÷ 2 = 2 1/4
2 1/4 = 2.25
2.25 = 30 minutes.
4.5 + 2.25 = 6.75.
1 hour + 30 mins. = 1 hour and 30 minutes.

However we can still keep going.

2.25 ÷ 2 = 1.125
1.125 in fraction form is 1 1/8
1.125  = 15 minutes
1 hour and 30 minutes  + 15 minutes = 1 hour and 45 minutes.
6.75 + 1.125 = 7.875
7.875 in fraction form is 7 7/8

Your answer would be it would take 1 hour and 45 minutes.

Final answer:

Pythagorean triples are sets of three whole numbers that form the sides of a right triangle and satisfy the Pythagorean theorem, a² + b² = c².

Explanation:

Pythagorean triples are unique because they consist of three whole numbers that satisfy the Pythagorean theorem.

Specifically, the squares of the two shorter sides (a and b), when added together, equal the square of the longest side (the hypotenuse, c). That is, a² + b² = c² holds true for these numbers.

Answering the student's question, the characteristic that is unique about Pythagorean triples is: C) The length of each side is a whole number.

This means that all three sides of the right triangle are integers, which is helpful in various mathematical and practical applications. Examples of Pythagorean triples include (3, 4, 5) and (5, 12, 13).
