Answers

The solutions to the equation are x = -3 and x = 0

How to determine the solution to the equation

from the question, we have the following parameters that can be used in our computation:

3/x - x/(x + 6) = 18/(x² + 6x)

Multiply through by x² + 6x

So, we have

3(x + 6) + x² = 18

Open the brackets

3x + 18 + x² = 18

Evaluate

x² + 3x = 0

When solved for x, we have

x = -3 and x = 0

The equation in vertex forms are;

a. f(x) = -5(x + 2)² - 3

b. f(x) = 1 + (x -1)² + 3

How to determine the equations

To determine the equation in vertex form, we have to know that the equation is represented as;

f(x) = a(x – h)² + k

Such that the parameters of the formula are expressed as;

a, h, and k are constants of the parabola is at (h, k).

i. Then, for the first graph, we have;

vertex : (-2, -3)

Then, we have that;

a = -5

Then, we get;

f(x) = -5(x + 2)² - 3

ii. Vertex : (1, 3)

But a = 1

Then ,

f(x) = 1 + (x -1)² + 3

Your answer should be an exact numerical whole number and do not use the percent symbol.
In a sample of 20 scores, the score 18 occurred 11 times. What is the relative frequency of the data value 18?
%

Answers

The relative frequency of the data value 18 is 55%.

To calculate the relative frequency of a data value, we divide the frequency of that value by the total number of scores in the sample and then multiply by 100 to express it as a percentage.

In this case, the frequency of the data value 18 is 11, and the total number of scores in the sample is 20.

Relative frequency of 18 = (Frequency of 18 / Total number of scores) * 100

= (11 / 20) * 100

= 55%

The data value 18 therefore has a relative frequency of 55%.

Find the x of 2^(x+1) = e^(1-x)

Answers

The natural logarithm of both sides of the equation indicates that the value of x is about 0.181

What is a logarithm?

A logarithm is an inverse of an exponential function, such that the logarithm of a number to a base is the exponent to which the base would be raised to obtain the number.

The equation can be presented as follows;

2⁽ˣ ⁺ ¹⁾ = e⁽¹⁻ˣ⁾

The natural logarithm of both sides of the equation indicates that we get;

ln(2⁽ˣ ⁺ ¹⁾) = ln(e⁽¹⁻ˣ⁾) = 1 - x

(x + 1) × ln(2) = 1 - x

x·ln(2) + x = 1 - ln(2)

x·(ln(2) + 1) = 1 - ln(2)

x = (1 - ln(2))/(ln(2) + 1) ≈ 0.181

A right triangle has a leg length of √8 and a hypotenuse length of 5. Determine the length of the other leg of the right triangle

Answers

Answer is

.

Let the length of the other leg be x. According to the Pythagorean theorem the sum of the squares of the lengths of the two legs of a right triangle equals the square of the length of the hypotenuse.

Therefore we have the equation:

√8^2 + x^2 =5^2

Simplifying this equation we get:

8 + x^2 = 25

Subtracting 8 from both sides we get:

x^2 = 17

Taking the square root of both sides we find:

x = √17

So the length of the other leg of the right triangle is √17.

On Saturday, the fruit and juice bar was selling 21 glasses of fruit punch an hour. By 5 p.m., they had sold 147 glasses. If their
goal was to sell more than 252 glasses of fruit punch, which inequality can be used to find h, the number of hours they must stay
open to make their goal?
OA. 21h<252+147
B. 147+21h <252
OC. 147+21h> 252
OD. 147+252 > 21h

Answers

Answer:

Among these options, the correct inequality is option C, 147 + 21h > 252.

Step-by-step explanation:

To find the correct inequality that represents the number of hours the fruit and juice bar must stay open to reach its goal, let's analyze the given information.

The bar sold 21 glasses of fruit punch per hour, and by 5 p.m., they had sold 147 glasses. The goal is to sell more than 252 glasses.

Let h represent the number of hours they must stay open. Since they sell 21 glasses per hour, the total number of glasses sold after h hours would be 21h.

To reach the goal of selling more than 252 glasses, the total number of glasses sold (21h) must be greater than 252. Therefore, the correct inequality is:

21h > 252

Looking at the answer choices:

A. 21h < 252 + 147

B. 147 + 21h < 252

C. 147 + 21h > 252

D. 147 + 252 > 21h

Among these options, the correct inequality is option C, 147 + 21h > 252. This inequality represents that the sum of the glasses already sold (147) plus the glasses sold in the remaining hours (21h) must be greater than the goal of 252 glasses.
