Answer:

Step-by-step explanation:

the answer would be D

we can rewrite the function as F(y) = y^2. notice that this function is written as F(y) rather than F(x). if this were a function of y we would write it as F(x)= squareroot(x)

the difference between a function of x and a function of Y is that in a Function of x the x value will be isolated and in a function of y the y value will be isolated.

Answer:Therefore, the percent change from 56 to 77 students is 37.5%.

Step-by-step explanation:

students, we can use the following formula:

percent change = ((new number - old number) / old number) x 100%

Plugging in the values given in the problem, we get:

percent change = ((77 - 56) / 56) x 100%

percent change = (21 / 56) x 100%

percent change = 0.375 x 100%

percent change = 37.5%

Therefore, the percent change from 56 to 77 students is 37.5%.

Answer:

81

Step-by-step explanation:

Given the relationships \(a \propto y^2\) and \(b \propto \frac{1}{y}\), let's solve for the proportionality constants and then use them to find \(x\) when \(y = 4\).

From the given values:

1. When \(x = 18\) and \(y = 2\), we have \(a + b + 4 = 18\).

2. When \(x = -3\) and \(y = 1\), we have \(a + b + 4 = -3\).

We can set up two equations using the given proportionalities and the given values:

Equation 1: \(a = ky^2\)

Equation 2: \(b = \frac{c}{y}\)

Substituting these into the first given condition:

\(ky^2 + \frac{c}{y} + 4 = 18\)

Substituting these into the second given condition:

\(ky^2 + \frac{c}{y} + 4 = -3\)

Solving these two equations will allow us to find the constants \(k\) and \(c\), and then we can use them to find \(x\) when \(y = 4\).

Let's solve the equations:

From the first equation:

\(k(2^2) + \frac{c}{2} + 4 = 18\)

\(4k + \frac{c}{2} + 4 = 18\)

\(4k + \frac{c}{2} = 14\)

From the second equation:

\(k(1^2) + \frac{c}{1} + 4 = -3\)

\(k + c + 4 = -3\)

\(k + c = -7\)

Now we have a system of two equations:

1. \(4k + \frac{c}{2} = 14\)

2. \(k + c = -7\)

Solve the second equation for \(k\): \(k = -c - 7\)

Substitute this into the first equation:

\(4(-c - 7) + \frac{c}{2} = 14\)

\(-4c - 28 + \frac{c}{2} = 14\)

\(-8c - 56 + c = 28\)

\(-7c = 84\)

\(c = -12\)

Substitute \(c\) back into \(k + c = -7\):

\(k - 12 = -7\)

\(k = 5\)

Now that we have \(k\) and \(c\), we can determine the values of \(a\) and \(b\) using the given proportionalities:

\(a = 5y^2\)

\(b = \frac{-12}{y}\)

Finally, substitute these values of \(a\), \(b\), and \(y\) into the equation \(x = a + b + 4\) to find \(x\) when \(y = 4\):

\(x = 5(4^2) + \frac{-12}{4} + 4\)

\(x = 80 - 3 + 4\)

\(x = 81\)

So, when \(y = 4\), \(x\) is 81.

The surface area of a cylinder can be found by adding the areas of the top and bottom circles, as well as the area of the side (lateral) surface.

The radius of the cylinder is 1 and one fourth centimeters, which can be written as 5/4 cm. The height of the cylinder is 3 and three fourths centimeters, which can be written as 15/4 cm.

The area of each circle is πr^2, where r is the radius. So, the area of the top and bottom circles is:

2π(5/4)^2 = 25/2 π square centimeters

The lateral surface area of a cylinder is given by the formula 2πrh, where r is the radius and h is the height. So, the lateral surface area of the cylinder is:

2π(5/4)(15/4) = 75/2 π square centimeters

Therefore, the total surface area of the cylinder is:

25/2 π + 75/2 π = 100/2 π = 50 π square centimeters

So, the exact surface area of the cylinder in terms of π is 50π square centimeters. None of the given options matches this answer.

[tex]x=-6\dfrac{7}{8}[/tex]

Step-by-step explanation:

[tex]Solve\:9\:\dfrac{1}{4}\:+\:x\:=\:2\:\dfrac{3}{8}[/tex]

Step 1:
Convert all mixed fractions to improper fractions.
This will make it easier to add and subtract

Mixed fraction [tex]a\dfrac{b}{c}[/tex] can be converted to an improper fraction using

[tex]a\dfrac{b}{c}=\dfrac{a\cdot \:c+b}{c}[/tex]

[tex]9\dfrac{1}{4}=\dfrac{9\cdot 4+1}{4} = \dfrac{37}{4}[/tex]

[tex]2\dfrac{3}{8}=\dfrac{2\cdot 8+3}{8} =\dfrac{19}{8}[/tex]

Step 2:
Replace every mixed fraction in the original equation with its equivalent improper fraction:
[tex]\dfrac{37}{4}+x=\dfrac{19}{8}[/tex]

Step 3
Solve for x

Answer:a

Step-by-step explanation:

The solution to the equation ax² + bx + c = 0 , has a graph that crosses the y-axis once and does not intersect the x-axis, then the equation has one real root and two complex conjugate roots that lie on either side of the axis of symmetry.

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

If the graph of the equation ax² + bx + c = 0 crosses the y-axis once, it means that the equation has one real root. This is because when x = 0, the equation becomes:

c = 0² + 0 + c = c

Therefore, the point (0, c) is on the y-axis, which means the graph crosses the y-axis once.

If the graph does not intersect the x-axis, it means that the discriminant b² - 4ac is negative. This is because the discriminant determines the nature of the roots of a quadratic equation, and when it is negative, the roots are complex (not real) and the graph does not intersect the x-axis.

So, the solution(s) of the equation ax² + bx + c = 0 are:

x = (-b ± √(b² - 4ac)) / 2a

Since the discriminant is negative, the term inside the square root is negative, and there are no real solutions for x. Instead, the solutions are complex conjugates of the form:

x = (-b ± i√(4ac - b²)) / 2a

where i is the imaginary unit. Since the real part of these solutions is -b/2a, which is the axis of symmetry of the parabola, and the parabola does not intersect the x-axis, the complex roots will be a conjugate pair that lie on either side of the axis of symmetry.

Hence , the quadratic equation is solved

Step-by-step explanation:

The volume of the cylinder is 62.83 cubic cm and the volume of. the cone is 20.94 cubic cm.

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

here, we have,

We know that,

It should be noted the to calculate the volume of a cylinder, we can use the formula V = πr²h, where r is the radius and h is the height. In this case, the height and radius of the cylinder and cone are the same.

For the cylinder:

Volume = π(2cm)²(5cm)

V = 20π

For the cone, we can use the formula

V = (1/3)πr²h:

V = (1/3)π(2cm)²(5cm)

V = 20/3π cubic cm (exact value)

Hence, to get an approximate decimal value, we can use a calculator to evaluate:

Volume of cylinder ≈ 62.83 cubic cm

Volume of cone ≈ 20.94 cubic cm

Answer:

x = 90,

3x = 270

Step-by-step explanation:

We have a polygon that has 6 sides. We need to use the formula [tex]S=(n-2)*180[/tex] so we can create an algebraic equation to solve for x.

n = number of sides

[tex]S=(6-2)*180[/tex]

Evaluate

[tex]S=720[/tex]

Now we need to create an algebraic equation to find the value of x.

[tex]3x + x +45+135+45+135=720[/tex]

Add like terms

[tex]4x+360=720[/tex]

Subtract 360 on both sides

[tex]4x=360[/tex]

Divide by 4

[tex]x=90[/tex]

The value of x = 90.

To solve for 3x, the equation means 3 * x. We know what x is, so we just plug in 90.

[tex]3*90=270[/tex]

[tex]3x=270[/tex]

To check our work, add up all angle measures to see if they add up to 720.

[tex]270+90+45+135+45+135=720[/tex]
