Answer:

x = 7

x = - 1

Step-by-step explanation:

2(x-3)²-32=0                      Add 32 to both sides

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

=====================

x - 3 = 4                                Add 3 to both sides

x - 3+3 = 4+3

x = 7

=====================

x - 3 = - 4                            Add 3 to both sides

x -3 +3 = - 4 + 3                      

x = - 1

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.

The x-intercepts of the parabola are [tex]\( x = -3 \) and \( x = 1 \)[/tex].

To find the x-intercepts of the parabola defined by the equation [tex]\( y = -3x^2 - 6x + 9 \)[/tex], we need to set y=0 and solve for x.

So, we have:

[tex]\[ -3x^2 - 6x + 9 = 0 \][/tex]

Now, let's solve this quadratic equation using the quadratic formula:

[tex]\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \]where \( a = -3 \), \( b = -6 \), and \( c = 9 \).\[ x = \frac{-(-6) \pm \sqrt{(-6)^2 - 4(-3)(9)}}{2(-3)} \]\[ x = \frac{6 \pm \sqrt{36 + 108}}{-6} \]\[ x = \frac{6 \pm \sqrt{144}}{-6} \][/tex]

[tex]\[ x = \frac{6 \pm 12}{-6} \][/tex]

Now, we have two possible values for x:

1. When [tex]\( x = \frac{6 + 12}{-6} = \frac{18}{-6} = -3 \)[/tex]

Step-by-step explanation:

To find this area, we can break it up into two rectangles, one with dimensions of 4x19 and another of 24x11. All we have to do is find the areas of both rectangles and add them together!

Since 4*19=76 and 11*24=264, we get D. 340 square units as our answer.

For this case we have that the area of the figure is given by the sum of the areas of two rectangles. The area of a rectangle is given by:

[tex]A = a * b[/tex]

Where:

a, b: They are the sides of the rectangle

[tex]A_ {1} = 24 * 11\\A_ {1} = 264[/tex]

On the other hand:

[tex]A_{2} = 4 * (4 + 11 + 4) = 4 * 19 = 76[/tex]

Thus, the total area is:

[tex]A_ {t} = 264 + 76\\A_ {t} = 340[/tex]

The simplified formula for calculating the monthly lease payment for a car is the sum of the depreciation fee and the finance fee. These are calculated based on the car's initial cost, residual value, and the lease factor.

In the context of car leasing, the simplified formula used to calculate the monthly lease payment is: depreciation fee + finance fee. The depreciation fee is calculated by subtracting the car's expected residual value at the end of the lease from its initial cost (MSRP) and then dividing this by the number of months in the lease. The finance fee is calculated as the sum of the MSRP and the residual value, multiplied by the lease factor or money factor which is essentially the interest rate.

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

[tex]y = - 2 {(x + 7)}^{2} + 2[/tex]

Step-by-step explanation:

95 pounds is equal to 43091.275 grams.

Multiply the mass value by 453.592

First, you must find the total number of people. Add together 32, 54, 78, 112, and 96 to get 372. Next, add the number of diabetic patients with the number of patients with eye problems (54 + 112 = 166).

Your fraction is now 116/372. Simplify this to get your answer, 29/93 or 0.31.

Answer:

Third option.

Step-by-step explanation:

You need to cube both sides of the equation. Remember the Power of a power property:

[tex](a^m)^n=a^{mn[/tex]

[tex]\sqrt[3]{162x^cy^5}=3x^2y(\sqrt[3]{6y^d})\\\\(\sqrt[3]{162x^cy^5})^3=(3x^2y(\sqrt[3]{6y^d}))^3\\\\162x^cy^5=27x^6y^36y^d[/tex]

According to the Product of powers property:

[tex](a^m)(a^n)=a^{(m+n)[/tex]

Then. simplifying you get:

[tex]162x^cy^5=162x^6y^{(3+d)}[/tex]

Now you need to compare the exponents. You can observe that the exponent of "x" on the right side is 6,  then the exponent of "x" on the left side must be 6. Therefore:

[tex]c=6[/tex]

You can notice that the exponent of "y" on the left side is 5,  then the exponent of "x" on the left side must be 5 too. Therefore "d" is:

[tex]3+d=5\\d=5-3\\d=2[/tex]

Answer:

[tex]f(x)=\frac{3}{5}(x+1)^2+4[/tex]

Step-by-step explanation:

The equation of a quadratic function in vertex form is given by:

[tex]f(x)=a(x-h)^2+k[/tex]

Where (h,k) is the vertex.

It was given in the question that the vertex of the parabola is (-1,4).

When we substitute the vertex into the formula we get:

[tex]f(x)=a(x+1)^2+4[/tex]

The parabola also passes through (4,19) hence it must satisfy its equation.

[tex]19=a(4+1)^2+4[/tex]

[tex]19-4=a(5)^2[/tex]

[tex]15=25a[/tex]

We divide both sides by 25 to get:

[tex]a=\frac{15}{25}= \frac{3}{5}[/tex]

Hence the quadratic function is:

[tex]f(x)=\frac{3}{5}(x+1)^2+4[/tex]
