What is the correct answer NEED ANSWER ASAP ​

Answer:

- \(\frac{35}{6}\)

Step-by-step explanation:

The additive inverse is the opposite of 6, that is - 6 ( 6 - 6 = 0 )

The multiplicative inverse is the reciprocal of 6 , that is \(\frac{1}{6}\) ( 6 × \(\frac{1}{6}\) = 1 )

Thus their sum is

- 6 + \(\frac{1}{6}\) = - \(\frac{36}{6}\) + \(\frac{1}{6}\) = - \(\frac{35}{6}\)

Answer:

- 5 5/6 or you can write it as -35/6.

Step-by-step explanation:

The additive inverse of 6 is -6 because 6 + (-6) = 0 while the multiplicative inverse is 1/6 because 6 * 1/6 = 1.

So the answer is  - 6 + 1/6 = - 5 5/6.

The area of the semicircle table after it is cut in half  \(=\frac{9}{2}\pi\) square units.

A semicircle is a 2 -D shape which is obtained by cutting a circle along with its diameter. a circle has 2 semicircles when it is cut along with its diameter.

The formula for finding the area of a semicircle is half of the area of a circle with the same radius.

area of semicircle = \(\frac{\pi r^{2} }{2}\) square units

Given:

A table with a round top is cut in half so now its shape is a semicircle.

After it is cut, the edge along the wall is 6 ft means that the diameter of the semicircle is = 6 ft

Diameter = 6 ft

Radius = diameter / 2

Radius = 6/ 2

Radius = 3 ft

Therefore now we can calculate the area of the table after it is cut in half

Area of the semicircle table after it is cut in half =

\(=\frac{\pi r^{2} }{2} \\=\frac{\pi 3^{2} }{2} \\=\frac{9\pi }{2}\\= \frac{9}{2}\pi\)

The area of the semicircle table after it is cut in half  \(=\frac{9}{2}\pi\) square units.

Answer:

About 45% increased

A planted seed has a 85% chance of growing into a healthy plant. The probability that exactly 4 out of 11 seeds don't grow is approximately 0.1302.

To calculate this probability, we can use the binomial distribution formula. In this case, each seed has a 15% chance of not growing (1 - 0.85). We want to find the probability that exactly 4 seeds out of 11 don't grow.

Using the binomial distribution formula, the probability can be calculated as:

\(P(X = 4) = (^{11}C_4) * (0.15)^4 * (0.85)^7\)

Where (\(^{11}C_4\)) represents the number of ways to choose 4 seeds out of 11, \((0.15)^4\)represents the probability of 4 seeds not growing, and\((0.85)^7\) represents the probability of the remaining 7 seeds growing.

Evaluating the formula, we find:

\(P(X = 4) = (11! / (4! * 7!)) \times(0.15)^4 \times (0.85)^7 \approx 0.1302\)

Therefore, the probability that exactly 4 out of 11 seeds don't grow is approximately 0.1302, or 13.02%.

Answer:

5+ 2x

Step-by-step explanation:

lets say x is our variable therefore you will multiply 2 to x and then it says 5 more the key word is more therefore you add 5 to your equation

The problem requires determining if the function f(x) = (3/7)√(7x) - 3 is increasing or decreasing at x = 0, using only the definition of increasing or decreasing functions.

To determine if the function f(x) = (3/7)√(7x) - 3 is increasing or decreasing at x = 0, we can use the definition of increasing or decreasing functions. According to this definition, a function is increasing if the derivative is positive and decreasing if the derivative is negative.

To find the derivative of f(x), we differentiate the function with respect to x. The derivative of (3/7)√(7x) - 3 is (3/7)(1/2)(7)(1/√(7x)) = (3/2√(7x)).

Now, to determine if the function is increasing or decreasing at x = 0, we substitute x = 0 into the derivative. However, at x = 0, the derivative is undefined since it involves dividing by zero (√(7x) becomes √(0) = 0 in the denominator).

Therefore, we cannot make a definitive conclusion about the function's increasing or decreasing behavior at x = 0 using only the definition of increasing or decreasing functions. The behavior of the function at x = 0 would require further analysis using other techniques, such as the first or second derivative test.

Based on the information provided, the number of cards (c) in each pack can be modeled by the following mathematical expression (equation):

Note: 100 cent is equal to 1 dollar.

First pack:        0.25c = 3

Second pack:  0.3c = 3

Now, we can determine the number of cards (c) in the first pack as follows:

0.25c = 3

c = 3/0.25

Number of cards, c = 12 cards.

For the second pack, we have:

0.3c = 3

c = 3/0.3

Number of cards, c = 10 cards.

Therefore, there are 12 cards in the first pack, and there are 10 cards in the second pack.

Difference = First pack - Second pack

Difference = 12 - 10

Difference = 2 cards.

In conclusion, the first pack has 2 more cards than the second pack.

Let the smallest angle in a triangle be = x

Largest angle in a triangle = 55 + x

The middle angle in a triangle = 3x ( triple the measure of the smallest angle )

Their sum = 180° ( according to the angle sum property all the angles of a triangle sum up to 180° )

This can be written as :

= x + 55 + × + 3x = 180

Let us find each angle by solving the equation .

= x + 55 + x + 3x = 180°

= x + x + 3x + 55 = 180°

= 5x + 55 = 180°

= 5x = 180 - 55 ( transposing +55 from LHS to RHS changes +55 to -55 )

= 5x = 125

= x = 125 ÷ 5 (transposing ×5 from LHS to RHS changes ×5 to ÷5 )

= x = 25

Using this let us find the measure of each angle .

Smallest angle = x = 25

Smallest angle = 25°

Middle angle = 3x = 3 × 25 = 75

Middle angle = 75°

The largest angle = x + 55 = 25 + 55 = 80

Largest angle = 80°

Therefore , the measure of the smallest angle = 25° , the measure of the middle angle = 75° and the measure of the largest angle = 80° .

We have that the measures of the  angles are as follows

\(\theta_1=80 \textdegree\)

\(\theta_2=75 \textdegree\)

\(\theta_3=25 \textdegree\)

From the question we are told that:

The measure of the middle angle  is triple the measure of the smallest angle

The measure of the largest angle is 55° greater  than the measure of the smallest angle

Let

\(\theta_1=Largest\ angle\)

\(\theta_2=Middle\ angle\)

\(\theta_3=Smallest\ angle\)

Therefore

\(\theta_1=55 \textdegree+\theta_3\\\\\theta_2=3*\theta_3\)

Generally, the equation for the angle of a triangle is mathematically given by

\(\theta_1+\theta_2+\theta_3=180\)

Therefore

\(55 \textdegree+\theta_3+3*\theta_3+\theta_3=180\)

\(\theta_3=25 \textdegree\)

Therefore

Substitute \(\theta_3\) into equations of \(\theta_1\) and \(\theta_2\)

For \(\theta_1\)

\(\theta_1=55 \textdegree+25 \textdegree\\\\\theta_1=80 \textdegree\)

For \(\theta_2\)

\(\theta_2=3*\theta_3\)

\(\theta_2=3*25 \textdegree\)

\(\theta_2=75 \textdegree\)

in conclusion

The measures of the  angles are as follows

\(\theta_1=80 \textdegree\)

\(\theta_2=75 \textdegree\)

\(\theta_3=25 \textdegree\)

The inflection points of the function f(x) = x⁴ - 2x²/3 are at

x = -0.77 and x = 0.77.

To find the inflection points of the function f(x) = x⁴ - 2x²/3, we need to locate the x-values where the concavity of the function changes.

This can be done by finding the second derivative of the function and determining where it equals zero.

First, let's find the second derivative of f(x):

f''(x) = 12x² - 4x/3

Setting f''(x) equal to zero and solving for x:

12x² - 4x/3 = 0

4x(3x - 1) = 0

This equation is satisfied when x = 0 and x = 1/3. However, we need to check the concavity around these points to confirm if they are inflection points.

By analyzing the sign of f''(x) in the intervals (-∞, 0), (0, 1/3), and (1/3, ∞), we observe that the concavity changes at x = -0.77 and x = 0.77.

These are the inflection points of the function f(x).

Therefore, the inflection points of f(x) = x⁴ - 2x²/3 are at x = -0.77 and x = 0.77.
