Answer:

Step-by-step explanation:

Please use " ^ " to indicate exponentation:   y= x^2 + 11x + 24.  Thanks.

Because x^2 is positive, the graph of this parabola opens up.

We can find the vertex and roots (zeros) as follows, using the quadratic formula:

With a = 1, b = 11 and c = 24,

       -11  ± √ [ (11^2-4(1)(24) ]       -11 ± √25

x = ------------------------------------ = --------------- = -3    and   x = -8

              2(1)                                     2

This tells us that the x-intercepts are at (-3, 0) and (-8, 0).  The minimum value is at x = -b / (2a), which here is x = -11 / [2] = -5 1/2 (which is halfway between the zeros).

The vertex (and thus, the minimum) is at (-5 1/2, f(-5 1/2) ).

Answer: y = -x + 9

Step-by-step explanation:

First, to find the slope of the line we will use: (y₂-y₁)/(x₂-x₁)

Using the two points, we get: (8-1)/(1-8)

Simplify it: 7/-7

Finally, the slope is -1

We can now write: y = -x + b

Next we will plug in a point into the equation we have:

(8,1)  -->   1 = -8 + b          Then solve algebraically

b = 9

Then finish the equation:

y = -x + 9

The equation in slope-intercept form for the line passing through the points (8,1) and (1,8) is y = -x + 9, calculated by first finding the slope and then using it to determine the y-intercept.

To write an equation in slope-intercept form of the line passing through the points (8,1) and (1,8), we first calculate the slope (m) using the formula m = (y2 - y1) / (x2 - x1). Substituting the given points gives us m = (8 - 1) / (1 - 8) = 7 / -7 = -1. With the slope and one of the points, we can then find the y-intercept (b) by rearranging the slope-intercept equation y = mx + b to b = y - mx, using one of the given points, for example, (8,1), which gives us b = 1 - (-1)(8) = 1 + 8 = 9. Therefore, the equation of the line in slope-intercept form is y = -x + 9.

Answer:62

Step-by-step explanation:

The differance between 2 consecutive even number is 2...so if the first consecutive even number is x, then the next 4 consecutive even number will(x+2),(x+4),(x+6),(x+8)

So

X+(x+2)+(x+4)+(x+6)+(x+8)=310

5x+20=310

So,x=58

As the third number is (x+4)

Putting the value of x the final result comes(58+4)=62.

2,2n+2,2n+4,2n+6,2n+8 - 5 consecutive even integers

2n+4 - 3rd number

[tex]2n+2n+2+2n+4+2n+6+2n+8=310\\10n+20=310\\10n=290\\n=29\\\\2n+4=2\cdot29+4=62[/tex]

To work out the volume of a prism, you multiply the area of cross-section by the height (or length).

So for a cylinder, you work out the area of the circle and then multiply it by the height.

Area of circle (or cross-section) = π × radius²

                                                = π × 0.7²

                                                = 0.49π   m²

Now to get the volume of the cylinder, you times this area of the cross-section by the height of the cylinder:

Volume = 0.49π × 1.5

            = 2.3 m³  (accurate to 2 decimal places)

---------------------------------------------------------------

Answer:

The maximum volume of rainwater the cylinder can hold is:

Answer:

B because u will have to first open the bracket according to BODMAS: bracket of division multiplication addition and subtract trust me before solving something like this use this BODMAS

Answer:

y = -1

Step-by-step explanation:

Details have been given in the question, we need to break them apart and create our equations accordingly.

"the sum of two times x and 3 times y is 5"

2x + 3y = 5

"the sum of two times x and 3 times y is 5"

x - y = 5

So, our two equations are:

2x + 3y = 5

x - y = 5

Solve using substitution method, by moving y to the other side.

x = y + 5

2(y + 5) + 3y = 5

2y + 10 + 3y = 5

Combine like terms

5y + 10 = 5

Subtract 10 from both sides

5y = -5

y = -1

[tex]\large\boxed{x^4+\dfrac{8}{7}x^3+6x+1}[/tex]

Step-by-step explanation:

In order to write any polynomial in standard form, you look at the degree of each term. You then write each term in order of degree, from highest to lowest.

We have:

[tex]\dfrac{8}{7}x^3+x^4+6x+1[/tex]

Look at the degrees for each term in the expression:

[tex]\dfrac{8}{7}x^3[/tex] has a degree of 3

[tex]x^4[/tex] has a degree of 4

[tex]6x[/tex] has a degree of 1

[tex]1[/tex] has a degree of 0

Write this trinomial in order by degree, highest to lowest

[tex]x^4+\dfrac{8}{7}x^3+6x+1[/tex]

The standard form of given equation is 8/7x^3 + x^4 + 6x + 1 is 7x^4 + 8 x^3 + 4 x + 7 = 0.

To write the equation 8/7x^3 + x^4 + 6x + 1 in standard form, you need to rearrange the terms in descending order of exponents.

Standard form for a polynomial is where the terms are written from the highest power to the lowest power of the variable.

So,  8/7x^3 + x^4 + 6x + 1 = 0

7x^4 + 8 x^3 + 4 x + 7 = 0.

Answer: [tex]x=2[/tex]

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope of the line and "b" is the y-intercept.

We know that the slope of this line is:

[tex]m=-\frac{3}{2}[/tex]

And the y-intercept is:

[tex]b=3[/tex]

Since the line intersects the x-axis when [tex]y=0[/tex],  we can substitute values into  [tex]y=mx+b[/tex]:

 [tex]0=-\frac{3}{2}x+3[/tex]

The final step is to solve for "x", then:

[tex]-3=-\frac{3}{2}x\\\\(-3)(-2)=3x\\\\6=3x\\\\x=\frac{6}{3}\\\\x=2[/tex]

The x-intercept of the line is 2.

We must figure out the value of x when the y-coordinate is 0, in order to identify the x-intercept of a line.

We can express the equation of the line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept,

Given that the slope of the line is -3/2 and the y-intercept is 3.

Substituting the given values into the equation, we have y = (-3/2)x + 3.

To find the x-intercept, we set y = 0 and solve for x:

0 = (-3/2)x + 3

Subtracting 3 from both sides:

(-3/2)x = -3

To isolate x, we multiply both sides by -2/3:

x = (-3)(-2/3)

x = 2

Therefore, the x-intercept of the line is 2.

Answer:

The length of LM is 4.24

Step-by-step explanation:

* Lets revise the rules in the right angle triangle when we draw the

 perpendicular from the right angle to the hypotenuse

- In triangle ABC

# Angle B is a right angle

# The hypotenuse is AC

# BD ⊥ AC

∴ (AB)² = AD × AC

∴ (BC)² = CD × AC

∴ (BD)² = AD × CD

∴ BD × AC = AB × BC

* Lets use one of these rules to solve the problem

∵ Δ JLK is a right triangle

∵ ∠L is a right angle

∵ LM ⊥ JK

- We can find LM by one of the rule above

∵ JM = 3

∵ MK = 6

∵ (LM)² = JM × KM

∴ (LM)² = 3 × 6 = 18 ⇒ take a square root for both sides

∴ LM = √18 = 3√2 ≅ 4.24

the ∡6 and ∡2 are both external angles, however they intercepted two arcs, a "far arc" and a "near arc", thus we'll use the far arc - near arc formula, as you see in the picture, and we'll use the inscribed angle theorem for the other two.

Answer:

Step-by-step explanation:

"The sum of -3x^2 or 3x^2 and 7x^2 is 10x^2" is false as it now stands.

If we combine -3x^2 and 3x^2, we get 0, so:

"The sum of -3x^2 or 3x^2 and 7x^2 is 10x^2" is equivalent to

"The sum of (expression) and 7x^2 is 10x^2".

Subtracting 7x^2 from both sides yields (expression) = 3x^2.

So:  Although "The sum of -3x^2 or 3x^2 and 7x^2 is 10x^2" is false,

"The sum of 3x^2 and 7x^2 is 10x^2" is true, and the formerly missing term is 3x^2.

Final answer:

The product rule for exponents allows you to add the exponents when multiplying two terms with the same base, simplifying the calculation. Examples include multiplying powers of the same number, or dealing with terms in scientific notation.

Explanation:

Understanding the Product Rule for Exponents

The product rule for exponents states that when you multiply two expressions with the same base, you can simply add the exponents. This rule simplifies the multiplication of exponentiated quantities.

Examples of Using the Product Rule

For instance, if you have 53 multiplied by 54, the product rule allows you to add the exponents: 53+4 = 57. Another example involves numbers in scientific notation. When you multiply 3.2 x 103 by 2 x 102, the result is 6.4 x 103+2 = 6.4 x 105.

If both terms have exponents, multiply the digit terms as usual and then add the exponents of the exponential terms. This concept also applies to logarithms, where the logarithm of a product of two numbers equals the sum of their individual logarithms.

The algebraic expression that represents the phrase 'the difference of the number of roses and 18 lilies' is 'r - 18'. The term 'difference' in math denotes subtraction operation.

In algebra, the phrase 'the difference of the number of roses and 18 lilies' is represented as a subtraction operation between two variables or a variable and a number. In this case, the expression can be represented as r - 18, where 'r' represents the number of roses and '18' represents the number of lilies. However, in this scenario, the type of the flower doesn't really matter, it's just about the quantity which is represented by the term '18'. The key term difference denotes subtraction in mathematical terms.
