a quadratic equation is an equation with a degree of 2.

well, is not 2x + x + 3 for sure, and is not 3x³ + 2x + 2 either, that one is a cubic, 3rd degree.

well, one would think is 0x² - 4x + 7, however 0x² is really 0, anything times 0 is 0, so the deceptive equation is really -4x + 7, which is not a quadratic.

5x² - 4x + 5 on the other hand is.

Answer:

D. Vertex (1, -25); intercepts x = -4, 6

Step-by-step explanation:

Vertex

x = -b/2a

x = - (-2)/2(1)

x = 2/2

x = 1

y = 1^2 - 2(1) - 24

y = 1 - 2 - 24

y = -25

Vertex (1, -25)

x-intercepts when y = 0

x^2 - 2x - 24 = 0

(x - 6)(x + 4) = 0

x - 6 = 0; x = 6

x + 4 = 0;x = -4

Answer

D. Vertex (1, -25); intercepts x = -4, 6

Answer:

(3x + 5)(4x - 7)

Step-by-step explanation:

The most common factors of 35 are 5 and 7. The 12 is a nuisance.

We could try 6 and 2 or 3 and 4 or even 12 and 1. You just have to juggle a bit to get the difference to be - x.  

I'm going to try 3 and 4 first with 5 and 7. The numbers you get for the middle term have to be quite close.

(3x     5)(4x      7) Oops. It's going to come out first try.

Now you need to get the middle term come to - 1

(3x   -  5)(4x  +    7)

Just to make it slightly harder, I'll do it the wrong way first.

-5*4x + 3x*7 = - 20x + 21x = x That is close. Only the signs are incorrect.

So try again.

(3x + 5)(4x - 7)

20x - 21x = - x

ANSWER

[tex]y = - 2{x}^{2} -28x - 96[/tex]

EXPLANATION

We have that

[tex]x = - 8 \: \: and \: \: x = - 6[/tex]

are the roots of the quadratic function.

This implies that

[tex]x + 8 \: \: and \: \: x + 6[/tex]

are factors of the quadratic function.

The quadratic function will have an equation of the form:

[tex]y = a(x + 8)(x + 6)[/tex]

It was also given that, the vertex of the function is at

[tex](-7, 2)[/tex]

This point must satisfy the equation.

This implies that:

[tex]2= a( - 7 + 8)( - 7+ 6)[/tex]

This implies that,

[tex]2=-a[/tex]

[tex]a = - 2[/tex]

We substitute the value of 'a' to get the equation in factored form as:

[tex]y = - 2(x + 8)(x + 6)[/tex]

We expand the parenthesis to write the equation in standard form.

[tex]y = - 2( {x}^{2} + 6x + 8x + 48)[/tex]

[tex]y = - 2( {x}^{2} + 14x + 48)[/tex]

[tex]y = - 2{x}^{2} -28x - 96[/tex]

Or in vertex form, the equation is

To find the slope and y-intercept of the equation -y = -0.9x + 4, multiply both sides by -1 to get y = 0.9x - 4, revealing a slope of 0.9 and a y-intercept of -4.

To find the slope and y-intercept of the graph -y = -0.9x + 4, we first need to rewrite the equation in the slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

By multiplying both sides of the equation by -1, we get y = 0.9x - 4. Here, it's clear that the slope (m) is 0.9 and the y-intercept (b) is -4.

This means that for every increase of 1 on the horizontal axis (x), there is a rise of 0.9 on the vertical axis (y). Additionally, the point where the line intersects the y-axis is at y = -4.

Answer:

x = 2.6667 (rounded)

Step-by-step explanation:

Move the constant to the right side and change its sign.

3x = 7 + 1.

Add the numbers.

3x = 8.

Divide both sides by 3.

x = 8/3 = 2.6667 (Rounded to the nearest ten-thousandth).

Hope this helps.

The solution of the equation, rounding the answer to the nearest ten-thousandth, is x = 2.6667.

To find the solution of the equation 3x - 1 = 7, we can follow these steps:

Step 1: Add 1 to both sides of the equation to isolate the term with x.

3x - 1 + 1 = 7 + 1

3x = 8

Step 2: Divide both sides of the equation by 3 to solve for x.

3x/3 = 8/3

x = 8/3

Step 3: Convert the fraction 8/3 to a decimal.

x ≈ 2.6667

Rounding the decimal to the nearest ten-thousandth, the solution of the equation is approximately x = 2.6667.

Answer:

3√3

Step-by-step explanation:

r = 3 cos θ

r = 2 - cos θ

First, find the intersections.

3 cos θ = 2 - cos θ

4 cos θ = 2

cos θ = 1/2

θ = -π/3, π/3

We want the area inside the first curve and outside the second curve.  So R = 3 cos θ and r = 2 - cos θ, such that R > r.

Now that we have the limits, we can integrate.

A = ∫ ½ (R² - r²) dθ

A = ∫ ½ ((3 cos θ)² - (2 - cos θ)²) dθ

A = ∫ ½ (9 cos² θ - (4 - 4 cos θ + cos² θ)) dθ

A = ∫ ½ (9 cos² θ - 4 + 4 cos θ - cos² θ) dθ

A = ∫ ½ (8 cos² θ + 4 cos θ - 4) dθ

A = ∫ (4 cos² θ + 2 cos θ - 2) dθ

Using power reduction formula:

A = ∫ (2 + 2 cos(2θ) + 2 cos θ - 2) dθ

A = ∫ (2 cos(2θ) + 2 cos θ) dθ

Integrating:

A = (sin (2θ) + 2 sin θ) |-π/3 to π/3

A = (sin (2π/3) + 2 sin(π/3)) - (sin (-2π/3) + 2 sin(-π/3))

A = (½√3 + √3) - (-½√3 - √3)

A = 1.5√3 - (-1.5√3)

A = 3√3

The area inside of r = 3 cos θ and outside of r = 2 - cos θ is 3√3.

The graph of the curves is:

The area of the region inside r=3cos(\theta) and outside r=2-cos(\theta) is obtained by integrating the square of each function times 1/2 over their intersection interval and subtracting the results.

The student is tasked with finding the area of a region bounded by two polar curves r=3cos(\theta) and r=2-cos(\theta). This involves sketching the curves to identify the area that lies inside the first curve and outside the second one. To find the area of the region, we calculate the difference between the integrals of the two functions over the interval where they intersect. This requires setting up and evaluating definite integrals in polar coordinates. The integral calculation would involve integrating the function r^2/2 from the lower to the upper bound of \(\theta\) for each curve and then subtracting the area inside r=2-cos(\theta) from the area inside r=3cos(\theta).

2(x-3)² - 32+32 = 32          Combine

2(x - 3)²  = 32                     Divide by 2

2(x - 3)² /2 = 32/2              Do the division

(x - 3)² = 16                         Take the square root of both sides

sqrt(x - 3)² = sqrt(16)           Do the square root.

x - 3 = +/- 4

Answer:

2568 kg

Step-by-step explanation:

30816 divided by 24 gives us 1284 or the total number of cartons which can then be multiplied by 2 to give us the weight of the empty cartons.

To find the total mass of the empty cartons, divide the total number of exercise books by the number of exercise books in each carton and then multiply by the difference in mass between a full and empty carton.

To find the total mass of the empty cartons, we need to determine how many cartons there are and the difference in mass between a full carton and an empty carton.

Given that each carton contains 24 exercise books and there are 30816 exercise books in total, we can calculate the number of cartons by dividing the total number of exercise books by 24.

So, there are 1284 cartons in total.

Now, we need to find the difference in mass between a full carton and an empty carton. The difference is 12 kg - 2 kg = 10 kg.

To find the total mass of the empty cartons, we multiply the number of cartons by the mass difference: 1284 cartons * 10 kg/carton = 12840 kg.

Therefore, the total mass of the empty cartons is 12840 kg.

Next, let's apply the ^1/4 to the x^16

To simplify the expression 3−9 · 36 · 36, we understand that 36 is 3 raised to the power of 6. Multiplying 36 by itself means adding the exponents, resulting in 3¹². Subtracting 9 (the minus sign before 9) from 12 (the exponent in 36 · 36), we get 3³, which is equal to 27.

To simplify the expression 3−9 · 36 · 36, we first need to understand the rules for cubing of exponentials and the operations of exponents.

To cube an exponential, you cube the base digit and multiply the exponent by 3.

For example, when cubing 3², we raise 3 to the power of 6 because the original exponent is multiplied by 3 (2×3=6), which gives us 3⁶, or in other words, 729.

In this case, however, we need to simplify the original expression.

We'll start by recognizing that 36 is 3 raised to the power of 6.

The expression states to multiply 36 by itself, which is essentially stating 3⁶ × 3⁶.

When multiplying exponents with the same base, we simply add the exponents, in this case, 6 + 6, which gives us 3¹².

Hence, the expression can be simplified to 3−9 · 3¹².

Now we are subtracting exponents (because of the minus sign), which means we take 9 away from 12 giving us 3³, or 3 cubed, which equals 27.
