Answer:

20

Using the formula of Pythagoras theorum 20 is the answer.

The number of hours Natalie worked babysitting last week is 6hrs and the number of hours she worked landscaping last week is 2 hrs.

Let x be the number of hours Natalie worked babysitting and y be the number of hours she worked landscaping. Then, the total earnings were 11x + 10y = $86.

Also, x = 3y, because she worked 3 times as many hours babysitting as she did landscaping.

Substitute x = 3y into the first equation:

11(3y) + 10y = $86

Expanding the first term we get,

33y + 10y = $86

Combining terms,

43y = $86

Dividing both sides by 43 we get,

y = $2

So, Natalie worked y = 2 hours of landscaping.

To find the number of hours she worked babysitting, substitute y = 2 into x = 3y as follows -

x = 3(2) = 6

So Natalie worked x = 6 hours babysitting.

Answer:

what is the question

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

-7 + 5x + -2x = 11 + 2x + -2x

Combine like terms: 5x + -2x = 3x

-7 + 3x = 11 + 2x + -2x

Combine like terms: 2x + -2x = 0

-7 + 3x = 11 + 0

-7 + 3x = 11

Add '7' to each side of the equation.

-7 + 7 + 3x = 11 + 7

Combine like terms: -7 + 7 = 0

0 + 3x = 11 + 7

3x = 11 + 7

Combine like terms: 11 + 7 = 18

3x = 18

Divide each side by '3'.

x = 6

Simplifying

x = 6

Answer:

x=6

Step-by-step explanation:

Solve 5x−7=2x+11.

Subtract 2x from both sides.

5x−7−2x=2x+11−2x

3x−7=11

Add 7 to both sides.

3x−7+7=11+7

3x=18

Divide both sides by 3.

\(\frac{3x}{3} =\frac{18}{3}\)

x=6

Using the inverse relation for the cubic root, we conclude that the correct option is the third one.

This is kinda a trivial question, as that is the definition of a root.

Actually, for any root we will have:

\(\sqrt[n]{x} = x^{1/n}\)

Now, using the inverse relation, we know that:

(∛x)^3 = x

Then:

(∛4)^3

Now, remember that:

(a^n)^m = a^(n*m)

Using that property, we can write like in option 3.

(4^(1/3))^3 = 4^( (1/3)*3) = 4^1 = 4

Then we can see that:

(∛4)^3  = (4^(1/3))^3

This means that ∛4 = 4^(1/3)

Then the correct option is the third one.

The solution of the given equation are (1/2 , 17/2) and (-3 , 12)

The two equation that we have been given are :

    y = 9 – x            (1)

    y = 2x² + 4x + 6       (2)

We will solve this simultaneously, from equation (1) we will equate the value of y in equation (2) we get

       9 – x = 2x² + 4x + 6

        3 = 2x² + 5x

2x² + 5x – 3 = 0

Now to find the factors of the value x we will use quadratic formula.

   x = (-b±√b² – 4ac)/2a

   x = [ -5 ± √25 + 24 ]/4

   x = [ -5 ± 7 ]/4

x = (-5 + 7)/4              and                 x = (-5 – 7)/4

x = 1/2     and    x= -3

putting the required value of x in equation (1) we get

y = 9 – 1/2            and             y = 9 – (-3)

y = 17/2      and    y = 12

Hence the solution of the equation is (1/2 , 17/2) and (-3 , 12)

In the formulas for constructing interval estimates based on sample proportions, the expression Pu (l - Pu) has a maximum value of 1/4.Let's discuss interval estimates based on sample proportions first. A proportion is the number of items in one category divided by the total number of items in all categories.

A sample is a smaller version of a population that we use to gather data and infer characteristics about the population. A confidence interval is a range of values that contains the true population parameter with a certain level of confidence. When we want to estimate the proportion of a population that has a certain characteristic, we use a sample proportion to estimate it.

A formula is used to construct a confidence interval around the sample proportion. The formula for constructing interval estimates based on sample proportions is given by: Lower Bound: P - zα/2 * sqrt(PQ/n)Upper Bound: P + zα/2 * sqrt(PQ/n)Where P is the sample proportion, Q is (1 - P), n is the sample size, and zα/2 is the z-score corresponding to the desired level of confidence. The expression Pu (l - Pu) has a maximum value of 1/4.

The distance that the tip of the hand travels as it moves from the 12 to the 3 is given as follows:

15.71 cm.

The distance traveled by the tip of the hand is dependent of the circumference of the circle.

The circumference of a circle of radius r is given by the multiplication of 2π and r, as follows:

C = 2πr.

The hand on the circular clock in the figure below measures 10 cm, hence the radius of the circle is given as follows:

r = 10.

Then the circumference of the circle is of:

C = 2π x 10 = 62.83 cm.

The entire circumference of the circle, containing 12 hours, is of 360º, hence the interval containing 3 hours has an angle of 3/12 x 360 = 90º = π/2, which is one fourth of the circumference.

Then the distance along this interval is given as follows:

D = 1/4 x 62.83 = 15.71 cm.

The value of x will be 34°

Given that

(x+12)°+100°+x° are forming linear pair

Linear pair of angles are formed when two lines intersect each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°. Such angles are also known as supplementary angles.

As mentioned, adjacent angles are angles that are next to each other. If you are sitting next to someone in class or on the bus, you could say that you are adjacent to them. More specifically, adjacent angles share a vertex and have a common side.

(x+12)°+100°+x°= 180°

⇒ x+ 12+ 100+x = 180°

⇒ 2x+112 = 180°

⇒ 2x = 180- 112

⇒ 2x = 68

⇒ x= 68/2

⇒ x= 34

For verification we will put value of x

(34+12)°+100°+34°

⇒ 46°+100°+34°

⇒146°+34°

⇒ 180°

So here we can see that by putting value of x we are getting the sum of 180°

Therefore value of x is 34

The equation used to find the distance of the flowerbed from the hive is called the "time equation".

The flowerbed is 900 feet far from the hive.

Find the traveling time

The bee spends 12 minutes hunting down the nectar in the flowerbed. Since it was away from the hive for a total of 16 minutes, the traveling time is

16min - 12min = 4 min

Convert the Minutes to seconds

1 minute = 60 seconds

4 minutes = 4*60 = 240 seconds

Find the time each way

The total time is 240 seconds, but it is not divided evenly.

Let the time there = t

Let the time back = 240 - t

The distances are the same

r = 10 m/s

r1 = 6 m/s

t1 = t

t2 = 240 - t

dthere = dback

d = rate * time

10 m/s *t = 6 m/s (240 - t)      

Remove the brackets on the right.

10 * t = 6*240 - 6t                

Combine the like terms on the right.

10t = 1440 - 6t                        

Add 4t to both sides

10t + 6t = 1440 - 6t + 6t          

Combine

16t = 1440                            

Divide both sides by 16

16t/16 = 1440/16                    

Do the division

t = 90

When the second derivative of a function equals zero, it indicates a possible point of inflection or a critical point where the concavity of the function changes. It is a significant point in the analysis of the function's behavior.

The second derivative of a function measures the rate at which the slope of the function is changing. When the second derivative equals zero at a particular point, it suggests that the function's curvature may change at that point. This means that the function may transition from being concave upward to concave downward, or vice versa.

Mathematically, if the second derivative is zero at a specific point, it is an indication that the function has a possible point of inflection or a critical point. At this point, the function may exhibit a change in concavity or the slope of the tangent line.

Studying the second derivative helps in understanding the overall shape and behavior of a function. It provides insights into the concavity, inflection points, and critical points, which are crucial in calculus and optimization problems.

When the second derivative of a function equals zero, it indicates a critical point in the function, which can be a maximum, minimum, or an inflection point.

The second derivative of a function measures the rate at which the slope of the function is changing. When the second derivative equals zero, it indicates a critical point in the function. A critical point is a point where the function may have a maximum, minimum, or an inflection point.

To determine the nature of the critical point, further analysis is required. One method is to use the first derivative test. The first derivative test involves examining the sign of the first derivative on either side of the critical point. If the first derivative changes from positive to negative, the critical point is a local maximum. If the first derivative changes from negative to positive, the critical point is a local minimum.

Another method is to use the second derivative test. The second derivative test involves evaluating the sign of the second derivative at the critical point. If the second derivative is positive, the critical point is a local minimum. If the second derivative is negative, the critical point is a local maximum. If the second derivative is zero or undefined, the test is inconclusive.
