Help me please!!!!! I need to get this done before 6:00 and it’s currently 5:45!!!

Answer:

9

Step-by-step explanation:

[tex] | \sqrt{130 \: } | { \: }^{2} \: = |7| {}^{2} + |x| { \\ }^{2} \\ [/tex]

= 130=49+x²

=130-49=x²

=81=x²

[tex] \sqrt{81 \: } = x \\ x = 9[/tex]

Therefore the third side is 9

The function f(x) is [tex]-32(x - 2)(x + 2)^2.[/tex].

A linear function has the equation f(x) = mx + b, where m is the slope and b is the y-intercept. In this case, g(x) is a linear function with an x-intercept of 2 (meaning it passes through the point (2,0)) and a slope of 4. So the equation for g(x) would be:

g(x) = 4(x - 2)

A quadratic function has the equation f(x) = [tex]a(x - h)^2[/tex] + k, where (h, k) is the vertex of the parabola. In this case, h(x) is a quadratic function with vertex (-2, -8) and passing through the origin (0, 0) so the equation for h(x) would be:

h(x) = [tex]-8(x + 2)^2[/tex]

Now since f(x) = g(x) ⋅ h(x), we can substitute the equation of g(x) and h(x) in the equation of f(x) to get the equation for f(x) :

f(x) = [tex]g(x) *h(x) = (4(x - 2)) * (-8(x + 2)^2)[/tex]

f(x) =[tex]-32(x - 2)(x + 2)^2[/tex]

So the function f(x) is [tex]-32(x - 2)(x + 2)^2[/tex].

Yes, 7×5×3×2 + 3 is a composite number.

A composite number is a positive integer that has at least one positive divisor other than 1 and itself. In other words, a composite number is a positive integer that can be written as a product of at least two positive integers.

In the number expressed by 7×5×3×2 + 3, we can take 3 as a common factor

7×5×3×2 + 3 = 3(7×5×2 + 1)

So the number has 3 as a factor other than 1 and itself, so it is a composite number.

Also 7×5×3×2 + 3 = 213 = 3×71. So it is not a prime number.

The lateral surface area of the prism is 81m².

All of an object's sides, excluding its base and top, are considered its lateral surface. The size of the lateral surface is referred to as its area. This must be distinguished from the total surface area, which consists of the base and top areas as well as the lateral surface area.

The total area of all of its faces is reduced to the lateral area. It can also be explained by multiplying the prism's height by the base's circumference.

The base's sides are each 7 meters long, which is a given.

Phase 7+7+7 = 21 meters is the perimeter.

We also know that the prism is 4 meters tall.

The lateral area is therefore

The solution to the system of equations y = 1.5x - 4 and y = -x  is (1.6,-1.6)

The coordinates of the ordered pair (s) that satisfy all of the system's equations make up the solution set to an equational system. This means that the equations will be true for those x and y values. The intersection of all of the graphs, when a system of equations is graphed, is the solution.

These are the equations:

y = 1.5x - 4

y = -x

Put y = -x in place of y in the first equation.

-x = 1.5x - 4

Assemble similar terms

-1.5x - x = -4

This results

-2.5x = -4

Add -2.5 to both sides.

x = 1.6

Change y = -x to x = 1.6.

y = -1.6

The nature of roots of the quadratic equation 5x^2 - 2x + 3 = 0 is complex number.

The nature of roots of a quadratic equation is determined by the discriminant, which is the value of b² - 4ac. In this case, the quadratic equation is 5x^2 - 2x + 3 = 0.

To find the discriminant, we can use the formula: b² - 4ac. In this case, a = 5, b = -2 and c = 3, so the discriminant is:

Discriminant = (-2)² - 4*5*3 = 4 - 60 = -56

The discriminant can be used to determine the nature of the roots:

If the discriminant is greater than 0, the roots are real and distinct.

If the discriminant is equal to 0, the roots are real and identical (i.e., the equation has only one root).

If the discriminant is less than 0, the roots are complex and not real numbers.

In this case, the discriminant is negative, so the roots of the equation 5x^2 - 2x + 3 = 0 are complex. The roots can be found by factoring the equation into (x + a + bi)(x + a - bi), where a and b are real numbers, and i is the imaginary unit (i² = -1).

y=x-1 is the equation of the line in slope intercept form.

The slope of the line is the ratio of the rise to the run, or rise divided by the run.

It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The two points from the graph are (1, 0) and (0, -1).

Slope= -1/-1

The value of the function f ( g ( 6 ) ) = -6

Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.

Given data ,

Let the first function be represented as f ( x )

Let the second function be represented as g ( x )

Now , the value of f ( x ) = 6 - x

The value of g ( x ) = x + 6

To calculate the value of f ( g ( 6 ) )

Substitute the value of x = 6 in the equation , we get

g ( 6 ) = 6 + 6 = 12

Substitute the value of x = 12 in f ( x ) , we get

f ( g ( 6 ) ) = f ( 12 )

The value of the composition function , we get

f ( 12 ) = 6 - 12

f ( 12 ) = -6

The inequality expression and solution to a system of inequalities graphically is xx + yy <= 18

We can represent the system of inequalities as follows:

xx + yy <= 18 (representing the maximum number of pieces of furniture that can be shipped)

A possible solution could be:

xx = 8 (number of tables sold)

yy = 10 (number of chairs sold)

100yy + 450xx >= 3200 (representing the minimum amount of money that must be made from the sale of chairs and tables)

xx >= 8 (representing the minimum number of tables that must be sold)

To graphically represent this system of inequalities, we can begin by graphing the first inequality in a coordinate plane. The inequality xx + yy <= 18 can be represented by a line with the equation y = -x + 18.

Next, we can graph the second inequality. The inequality 100yy + 450xx >= 3200 can be represented by a line with the equation y = -(4.5/5)x + 80.

Finally, we can graph the third inequality, which is a horizontal line at y = 8.

Now we can graph these three inequalities, one line for each inequality, and see where they intersect. The point where all three lines intersect is one possible solution for the system of inequalities.

A possible solution could be:

xx = 8 (number of tables sold)

yy = 10 (number of chairs sold)

The Law of Cosines states that for a triangle with sides a, b, and c and with angle C opposite side c, the relationship between the sides and the cosine of the angle is:

c^2 = a^2 + b^2 - 2ab * cos(C)

Since the triangle is a right triangle, we can use the Pythagorean theorem to find the value of the angle.

For ∠A:

c^2 = a^2 + b^2 - 2ab * cos(A)

9^2 = 5^2 + 7^2 - 257 * cos(A)

81 = 25 + 49 - 70 * cos(A)

81 = 74 - 70 * cos(A)

81 - 74 = -70 * cos(A)

7 = -70 * cos(A)

cos(A) = -7/70

A = arccos(-7/70)

For ∠B:

a^2 = b^2 + c^2 - 2bc * cos(B)

5^2 = 7^2 + 9^2 - 279 * cos(B)

25 = 49 + 81 - 98 * cos(B)

25 = 130 - 98 * cos(B)

130 - 25 = 98 * cos(B)

105 = 98 * cos(B)

cos(B) = 105/98

B = arccos(105/98)

For ∠C:

b^2 = a^2 + c^2 - 2ac * cos(C)

7^2 = 5^2 + 9^2 - 259 * cos(C)

49 = 25 + 81 - 90 * cos(C)

49 = 106 - 90 * cos(C)

106 - 49 = 90 * cos(C)

57 = 90 * cos(C)

cos(C) = 57/90

C = arccos(57/90)

Keep in mind that the values of the angle are in radians.

Please note that the triangle does not have to be a right triangle, the Law of Cosines works for any triangle.

12 of the 30 watermelons were ripe. The fractions of the watermelon that are ripe can be calculated as follows:

fraction of watermelon that are ripe = 12 / 30

fraction of watermelon that are ripe = 6 / 15

fraction of watermelon that are ripe = 2 / 5

Hence, the percentage of the water melon that are ripe can be calculated as follows:

1/2 * 3/5 * -17/8 = (-3/10) * (-17/8)

To multiply the fractions we multiply the numerators and denominators separately:
