Step-by-step explanation:

The value of the given expression [\(87^3+ 13^3/87^2 -87 * 13 + 13^2\)] by simplifying the numerator and denominator using suitable identities is 100.

We will first calculate the numerator:

As  (\(a^3\) + \(b^3\)) = (a + b)(\(a^2\) - ab + \(b^2\)) :

\(87^3\) + \(13^3\) = (87 + 13)(\(87^2\) - \(87 * 13\) + \(13^2\))

= 100(\(87^2\) - 87 * 13 + \(13^2\))

Now, calculate the denominator:

\(87^2 - 87 * 13 + 13^2\)

As,(\(a^2 -2ab +b^2\)) =\((a - b)^2\):

\(87^2 - 87 * 13 + 13^2 = (87 - 13)^2\)

\(= 74^2\)

So by solving the equation further:

\((87^3+13^3) / (87^2- 87 * 13+13^2) = 100*(87^2- 87 *13 + 13^2)/(87^2 - 87 * 13 + 13^2)\)

As we can see the numerator and denominator are the same expressions (\(87^2 - 87 * 13 + 13^2\)). so, they cancel each other:

\((87^3 + 13^3) / (87^2 - 87 * 13 + 13^2) = 100\)

So, the value of the given expression is 100.

Answer:

The answer is -1/9

Step-by-step explanation:

The slope of a perpendicular line is the opposite reciprocal.

To find the slope you take the given slope (9) and flip the reciprocal which results it turning into 1/9.

Then make it the opposite value. Like switching a negative to a positive or a positive to a negative. For this case, you make 1/9 into a -1/9

Adding all of the remaining pizzas, and dividing the total pizza into 5 equal fractions, the fraction of pizza that each person gets would be 11/24

A mixed number is a combination of a whole number and a fraction. For example, 3 1/2 is a mixed number. It is different from an improper fraction, which is a fraction where the numerator is greater than or equal to the denominator. For example, 7/4 is an improper fraction.

To convert a mixed number to an improper fraction, you must first multiply the whole number by the denominator of the fraction. Then add the result to the numerator. Finally, place the sum over the denominator. For example, to convert 3 1/2 to an improper fraction, you would first multiply 3 by 2 (the denominator of the fraction 1/2) to get 6, then add 1 (the numerator of the fraction 1/2) to get 7. So 3 1/2 is equivalent to 7/2 as an improper fraction.

So to find out the fraction of a whole pizza  that each person gets out of the different remaining pizzas, first we need to all the remaining pizzas as shown below,

3/4 of pepperoni + 5/8 of cheese + 11/12 of sausage = 55/24

Now to equally divide this into 5 person, we need to divide this fraction by 5,

i.e 55/(24*5) = 11/24

Therefore, each person gets 11/24 of the whole pizza.

Answer:  sometimes

Step-by-step explanation:

Answer:

first 2 hours: 276m

first 5 hours: 690m

15 minutes: 34.5m

Step-by-step explanation:

take the total distance climbed and divide it by the total time. this gives you 138m per hour climbed. just multiply this by your hours needed. divide by 4 to find the 15 minute distance.

The results are:

They climbed in the first two hours = 276 meters

They climbed in the first 5 hours = 690 meters

They climbed in the final 15 minutes = 34.5 meters.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

In 2011, a professional climber scaled the outside of the Burj Khalifa, making it all the way to 828 meters (the highest point on which a person can stand) in 6 hours.

Assuming they climbed at the same rate the whole way.

So, the unit rate,

= 828/6

= 138 meters per hour.

And 138/60 = 2.3 meter per minute.

They climbed in the first two hours,

= 2 x 138

= 276 meters.

They climbed in the first 5 hours,

= 5 x 138

= 690 meters.

They climbed in the final 15 minutes,

= (15 x 2.3)

= 34.5

= 34.5 meters.

Therefore, the results are 276 meters, 690 meters and 34.5 meters in the order.

Answer:

x = 1   ,or   x = -7

Obviously, the true answer is not in the options given.

Step-by-step explanation:

x² + 6x - 6 = 10

The above equation can not be factorized, hence the use of Almighty Formula.

x = [-b +- √b² - 4ac] / 2a

Where a = 1, b = 6, c = -6

x = [-6 +- √6² - (4*1*-6)] / 2*1

x = [-6 +- √36 - (-24)] / 2

x = [-6 +- √36 + 24] / 2

x = [-6 +- √60] / 2

x = [-6 +- 7.75] / 2

x = [-6 + 7.75] / 2   ,or   x = [-6 - 7.75] / 2

x = 1.75/2   ,or   x = -13.75/2

x = 0.875   ,or   x = -6.875

Approximately

x = 1   ,or   x = -7

Answer:   w = 7,  x = 6

Step-by-step explanation:  Solve by substitution

W + b = 13

rewrite as   b = 13 - w  and substitute that value for b in the second equation

6.5w + 2b = 57.5  Then solve for w

6.5w + 2(13-w) = 57.5 . Distribute

6.5w + 26 - 2w = 57.5 .  Subtract 26 from both sides. Combine like terms and simplify

6.5w - 2w = 57.5 - 26

4.5w = 31.5  Divide both sides by 4.65

w = 7 . Substitute 7 for w in the first equation and solve for b

7 + b = 13 . Subtract 7 from both sides

b = 6

The general solution of the given differential equation (x + 1) dy/dx + (x + 2)y = 2\(xe^{-x}\) is y = \(Cx^{-x}\) + x - 2, where C is a constant.

In order to find the general solution, we can rearrange the equation by dividing both sides by (x + 1):

dy/dx + (x + 2)/(x + 1)y = 2\(xe^{-x}\)/(x + 1).

Next, we notice that the left-hand side can be rewritten as the derivative of y with respect to x times a function of x. This suggests that the equation can be solved using an integrating factor. The integrating factor is given by the exponential of the integral of (x + 2)/(x + 1) with respect to x:

IF = e^{(∫(x + 2)/(x + 1) dx) }  = \(e^{x+2}\)ln|x + 1|.

multiplying both sides of the equation by the integrating factor, we obtain:

\(e^{x+2}\)ln|x + 1|dy/dx + (x + 2)\(e^{x+2}\)ln|x + 1|y = 2xe^(-x)\(e^{x+2}\)n|x + 1|.

Simplifying the equation further, we have:

d/dx (\(e^{x+2}\)ln|x + 1|y) = 2xln|x + 1|.

Integrating both sides with respect to x, we get:

\(e^{x+2}\)ln|x + 1|y = x^2ln|x + 1| + C,

where C is the constant of integration. Finally, solving for y, we obtain the general solution:

y = (\(x^{2}\)ln|x + 1| + C)/(\(e^{x+2}\)ln|x + 1|) = Ce^(-x) + x - 2,

Step-by-step explanation:

Area of the parking lot = Area of the whole structure - Area of the building

The building is a square of 12cm by 12cm

which is 72ft by 72ft since 1 cm is 6 ft

its area is thus 72 * 72 = 5,184 ft^2

The structure measures 16.5 cm by 22.5 cm

Multiplying the sides by 6, we have 99 ft by 135 ft

So its area is 99 * 135 = 13,365 ft^2

Researchers conducted a study and obtained  the p-value is 0.30, which is higher than the common significance level of 0.05. This means that there is not enough evidence to reject the null hypothesis, but it does not mean that the null hypothesis is accepted.

Hence this statement is false.

When researchers conduct a study and obtain a p-value, they use it to make a decision regarding the null hypothesis.

However, a high p-value does not provide evidence to accept the null hypothesis.

Instead, it indicates that there is not enough evidence to reject the null hypothesis.
1. Researchers start with a null hypothesis (H0), which is a statement that there is no effect or relationship between variables being studied.

They also have an alternative hypothesis (H1), which is a statement that there is an effect or relationship between variables.
2. They collect data and perform statistical tests to calculate the p-value, which represents the probability of observing the test results (or more extreme results) assuming the null hypothesis is true.
3. The p-value is then compared to a pre-determined significance level (alpha), commonly set at 0.05 or 5%.

If the p-value is less than the significance level, researchers reject the null hypothesis in favor of the alternative hypothesis.
4. In this case, the p-value is 0.30, which is higher than the common significance level of 0.05.

This means that there is not enough evidence to reject the null hypothesis, but it does not mean that the null hypothesis is accepted.
5. Instead, researchers should say that they "fail to reject" the null hypothesis, meaning they cannot confidently conclude that the alternative hypothesis is true based on the data and analysis.
