7. Find The Values Of C That Satisfy Rolle's Theorem. Show Steps

Answers

Answer 1

The values of c that satisfy Rolle's Theorem is 2.15 or -0.15.

What is the value of c that satisfy Rolle's Theorem?

The value of c that satisfies Roll's theorem is calculated as follows;

y = x³ - 3x² - x; [-1, 3]

Based on Roll's theorem conditions, since the function is a polynomial it is continuous.

The derivative is also a polynomial.

y' = 3x² - 6x - 1

The final condition;

y(-1) = (-1)³ - 3(-1)² - (-1)

y(-1) = -1 - 3 + 1

y(-1) = -3

y(3) = (3)³ - 3(3)² - 3

y(3) = 27 - 27 - 3

y(3) = -3

The three conditions of Rolle's theorem is statisfied,  so there exists at least one value of c in the interval (-1, 3) such that y'(c) = 0.

y' = 3x² - 6x - 1

y'(c) = 3c² - 6c - 1

3c² - 6c - 1 = 0

Solve the quadratic equation using formula method;

a = 3, b = -6, c = -1

c = 2.15 or - 0.15

[tex]x-\sqrt{x} +4-2\sqrt{x+3} =0\\[/tex]

Answers

The solution of the equation x - √x + 4 - 2√(x+3) =0 is given by x ≈ 0.449 or x = 2.

The expression is equal to,

x - √x + 4 - 2√(x+3) =0

By rearranging the terms and simplifying the expression as follows,

x - √x + 4 - 2√(x+3) = 0

⇒x + 4 = √x + 2√(x+3)

Square both sides to eliminate the square root,

⇒ (x + 4)² = (√x + 2√(x+3))²

⇒ x² + 8x + 16 = x + 4(x+3) + 4√x√x+3

⇒x² + 8x + 16 -x -4x -12 = 4√x√x+3

⇒ x² + 3x + 4 = 4√x√x+3

⇒x² + 3x + 4 = 4√x√(x+3)

⇒ x² + 3x + 4 = 4√(x²+3x)

Squaring both sides again gives,

⇒ (x² + 3x + 4)² = 16(x²+3x)

Expanding the left side gives,

x⁴ + 6x³ + 17x² + 24x + 16 = 16x² + 48x

Simplifying and rearranging the terms,

x⁴ + 6x³ + x² - 24x + 16 = 0

Factor this equation as follows,

(x² + 4x - 2)(x² + 2x - 8) = 0

The solutions are,

x²+ 4x - 2 = 0 or x² + 2x - 8 = 0

Solve each quadratic equation using the quadratic formula,

For x² + 4x - 2 = 0

x = (-4 ± √(4² - 4(1)(-2))) / (2(1))

⇒ x = (-4 ± √24) / 2

Simplifying the expression under the square root gives,

⇒ x = (-4 ± 2√6) / 2

⇒ x = -2 ± √6

For x² + 2x - 8 = 0

x = (-2 ± √(2² - 4(1)(-8))) / (2(1))

⇒x = (-2 ± √36) / 2

Simplifying the expression under the square root gives,

⇒ x = (-2 ± 6) / 2

⇒ x = -4 or x = 2

Discard the negative solution -2-√6 and -4

As it would lead to a negative value under the square root.

The final solutions are,

x ≈ 0.449 or x = 2

Therefore, the solution of the given equation is equal to x ≈ 0.449 or x = 2.

A biker traveled 2/5 of the road on the first day, then traveled 5 kilometers less on the next day, which is equal to 3/8 of the road. How much more does he need to travel? (distance)

Answers

The biker needs to travel 45 km more to complete his journey.

Given that, a biker traveled 2/5 of the road on the first day, then traveled 5 kilometers less on the next day, which is equal to 3/8 of the road, we need to find how much he need to cover more,

Let the total distance of the road be x,
So,

2x/5 - 5 = 3x/8

2x/5 - 3x/8 = 5

Solving for x,

Multiply by 40 to both sides,

16x-15x = 200

x = 200

Therefore, the total distance of the road is 200 km.

Since, he travelled =

200 (2/5) = 80 km + 200 (3/8) = 75 km = 155 km

Therefore, he needs to travel 200-155 = 45 km more.

Hence, the biker needs to travel 45 km more to complete his journey.

Answers

Step-by-step explanation:

Arithmetic sequence with  d = 2    a1 = -6

a20 = -6 + 2(20-1) = 32

The given sequence is an arithmetic sequence with a common difference of 2.

To find the 20th term, we can use the formula:

an = a1 + (n - 1)d

where
an is the nth term of the sequence
a1 is the first term of the sequence
d is the common difference between the terms
n is the term we want to find

We are given that a1 = -6, d = 2, and n = 20. Substituting these values into the formula, we get:

a20 = -6 + (20 - 1)2
a20 = -6 + 38
a20 = 32

Therefore, the 20th term of the sequence is 32.

We have,

The formula given is incorrect.

The correct formula for Pythagorean triples with a given integer z is:

(z² - 1², 2z, z² + 1²)

Using this formula, we can find the two legs of the right triangle with hypotenuse 29 as follows:

z² + 1² = 29²

z² + 1 = 29²

z² = 29² - 1

z² = 840

z = √840

z = 28.98

Since z must be an integer, we can try integer values close to 28.98 to find one that works.

Trying z = 29,

a = z² - 1² = 840 - 1 = 839

b = 2z = 58

c = z² + 1² = 840 + 1 = 841

Therefore,

The lengths of the two legs of the right triangle are 58 and 839, in increasing order.

Answers

The simplification of the given expression is equal to 192524.3.

The expression is equal to,

√2 × √6 × √110 × √120 × √450 × √520

Simplify this expression by first simplifying the square roots under the radical signs,

√2 = √(2 × 1)

     = √2 × √1

√6 = √(2 × 3)

     = √2 × √3

√110 = √(2 × 5 × 11)

        = √2 × √5 × √11

√120 = √(2 × 2 × 2 × 3 × 5)

        = 2√2 × √3 × √5

√450 = √(2 × 3² × 5²)

         = √2 × (3 × 5)²

         = 15√2

√520 = √(2³ × 5 × 13)

        = 2√2 ×√5 × √13

Substituting these simplifications back into the original expression, we have,

How many liters each of a 50% acid solution and a 60% acid solution must be used to produce 60 liters of a 55% acid solution? (Round to two decimal places if necessary.)

Answers

To produce 60 liters of a 55% acid solution, we need 18 liters of a 50% acid solution and 42 liters of a 60% acid solution.

Let x be the number of liters of the 50% acid solution needed, and y be the number of liters of the 60% acid solution needed.

We can set up two equations based on the amount of acid and the total volume:

0.50x + 0.60y = 0.55(60)

x + y = 60

Simplifying the first equation:

0.50x + 0.60y = 33

5x + 6y = 330 (multiplying both sides by 10)

We can solve for one variable in terms of the other in the second equation, and substitute into the first equation:

y = 60 - x

5x + 6(60 - x) = 330

Simplifying:

x = 18

So we need 18 liters of the 50% acid solution, and:

y = 60 - x = 42

So we need 42 liters of the 60% acid solution.

A second polygon A prime B prime C prime in quadrant 4 with point A prime at 3 comma negative 1. 90° clockwise rotation 180° clockwise rotation 180° counterclockwise rotation 90° counterclockwise rotation

Answers

To determine the direction and angle of rotation needed to move the original triangle ABC to the new polygon A' B' C', we can use a vector-based approach.

First, we can find the translation vector that moves point A to point A':

translation vector = A' - A = (3, -1) - (1, 3) = (2, -4)

Next, we can find the vector that connects point B to point A in the original triangle ABC:

vector AB = B - A

Then, we can rotate this vector using the rotation matrix for the desired angle of rotation:

90° clockwise rotation:
|0 -1| |x| |y'|
|1 0| * |y| = | -x'|

180° clockwise rotation:
|-1 0| |x| |x'|
| 0 -1| * |y| = |y'|

180° counterclockwise rotation:
|-1 0| |x| |-x'|
| 0 -1| * |y| = |-y'|

90° counterclockwise rotation:
| 0 1| |x| |-y'|
|-1 0| * |y| = | x'|

Finally, we can add the translation vector to the rotated vector to get the coordinates of the corresponding point in the new polygon A' B' C':

90° clockwise rotation: B' = A' + (AB rotated 90° clockwise + translation)
180° clockwise rotation: B' = A' + (AB rotated 180° clockwise + translation)
180° counterclockwise rotation: B' = A' + (AB rotated 180° counterclockwise + translation)
90° counterclockwise rotation: B' = A' + (AB rotated 90° counterclockwise + translation)

Using this method, we can find the coordinates of points B' and C' in the new polygon A' B' C'. Then, we can use the coordinates of these points to determine the direction and angle of rotation needed to move the original triangle to the new polygon.

The equation will have the solution in the form of an imaginary number "i" as: x = (3 ± 2i)/2

What is an imaginary number in a quadratic equation

In a quadratic equation, an imaginary number is a complex number that can arise when trying to take the square root of a negative number.

We shall solve for x in the equation as follows:

(2x + 3)² - 2 = -6

add 2 to both sides

(2x + 3)² = 2 - 6

(2x + 3)² = -4

2x + 3 = √(-4) {taking square root of both sides}

subtract 3 from both sides

2x = 3 ± √(-4)

divide through by 2

x = [3 ± √(-4)]/2

note that: √(-4) = √(1-) × √4 where √(-1) = I, so;

g o f ( x ) = 250 + 8x² - 92x

Now , the composition of function is

g o f ( -7 ) = 8 ( -7 )² - 92 ( -7 ) + 250

g o f ( -7 ) = 392 + 894

g o f ( -7 ) = 1,286

Hence , the function is g o f ( -7 ) = 1,286

The displacement of a train starting from a stop is given by the equation s(t) = 8\sqrt{t}+1 meters. Estimate the instantaneous velocity of the train at t = 9 seconds by considering the average velocities over the intervals [8.5, 9], [8.7, 9], [8.9, 9], [8.99, 9], [9, 9.01], [9, 9.1], [9, 9.3], and [9, 9.5].

Answers

The instantaneous velocity of the train at t = 9 seconds is approximately 6.8 m/s

To estimate the instantaneous velocity of the train at t = 9 seconds, we can consider the average velocities over several small intervals of time that include the point t = 9. This is an approximation of the slope of the tangent line to the curve s(t) at t = 9, which is the instantaneous velocity.

We can calculate the average velocity over each interval by dividing the change in displacement by the change in time:

Average velocity from [8.5, 9] = (s(9) - s(8.5)) / (9 - 8.5) = (8√9 + 1 - 8√8.5 + 1) / 0.5 = 6.34 m/s (approx.)

Similarly, we can calculate the average velocities over the other intervals:

[8.7, 9]: 6.48 m/s (approx.)

[8.9, 9]: 6.60 m/s (approx.)

[8.99, 9]: 6.66 m/s (approx.)

[9, 9.01]: 6.67 m/s (approx.)

[9, 9.1]: 6.74 m/s (approx.)

[9, 9.3]: 6.87 m/s (approx.)

[9, 9.5]: 7.00 m/s (approx.)

As we consider smaller intervals closer to t = 9, the average velocities approach a limit, which is the instantaneous velocity at t = 9. In this case, we see that the average velocities are increasing as we approach t = 9, indicating that the instantaneous velocity at t = 9 is also increasing.

Based on these calculations, we can estimate that the instantaneous velocity of the train at t = 9 seconds is approximately 6.8 m/s (averaging the average velocities from [8.99, 9] to [9, 9.5]).

The given shape of the distribution is not symmetric.

Given that, a box plot shows donations in dollars to charity.

We need to describe the shape of the distribution.

Donations to Charity ($) =

20 40 60 80 100 120 140 160 180 200 220

so, as we can see,

The shape of the distribution is not symmetric since the lengths of each box and whisker are not the same. There is an outlier at 220.

Hence, the given shape of the distribution is not symmetric.

The trio of sides that will make a right triangle are the ones in the first option:

5, 12, and 13.

Which set would make a right triangle?

Remember that for any right triangle, the sum of the squares of the two shorter sides must be equal to the square of the longest side.

So for example, for the first option we would have:

5^2 + 12^2 = 13^2

25 + 144 = 169

169 = 169

The equation is true, thus, these sides make a right triangle.

Mrs.lealas living room has an area of 144 square feet.

Her dining room is ⅓ the area of the living room and ⅖ the area of the kitchen. What is the area, in square feet, of the kitchen?

Answers

The Area of Kitchen is 120 square feet.

We have,

Area of living room = 144 square feet

So, the dining room

= 1/3 (area of living room)

= 1/3 (144)

= 48 square feet

and, Area of Dining room = 2/5 x Area of kitchen

48 =  2/5 x Area of kitchen

Area of kitchen = 48 x 5/2

Area of Kitchen = 24 x 5

Area of Kitchen = 120 square feet
