a) The velocity of the particle is described by v(t) = - 3 · t² + 12 · t - 9.

b) The particle is at rest when t = 1 s. and t = 3 s.

c) The particle changes its direction when t = 1 s. and t = 3 s.

d) The particle is moving right when 0 s < t < 1 s and t > 3 s and left when 1 s < t < 3 s.

e) The acceleration of the particle is described by a(t) = a(t) = - 6 · t + 12.

f) The velocity increases at t = 1 s.

g) The particle has a total distance of 54 meters.

In the statement we find the function of a particle that describes its position (y), measured in meters, in time (t), in seconds. Herein we shall analyze the function to determine all important features.

a) The velocity of the particle (v), in meters per second, is the first derivative of the function position:

v(t) = - 3 · t² + 12 · t - 9

b) The particle is at rest when v(t) = 0. Now we proceed to determine the roots of the resulting polynomial:

- 3 · t² + 12 · t - 9 = 0

t = 3 s. or t = 1 s.

c) The particle changes its direction when v(t) = 0. Then, this change happens in t = 1 s and t = 3 s.

d) The particle is moving right when v(t) > 0, then:

(t - 1) · (t - 3) > 0

There are two possible intervals: (i) 0 s < t < 1 s, (ii) t > 3 s. The particle is moving left when 1 s < t < 3 s.

e) The acceleration is the second derivative of function position, thus:

a(t) = - 6 · t + 12

f) The velocity increases when a(t) > 0. Then, the acceleration at t = 1 s is:

a(1) = - 6 · 1 + 12

a(1) = 6

The velocity is increasing at t = 1 s.

g) The total distance (s), in meters, traveled is determined by the following expression:

s = |x(1) - x(0)| + |x(3) - x(1)| + |x(6) - x(3)|

s = |7 - 11| + |11 - 7| + |- 43 - 11|

s = |- 4| + |4| + |- 54|

s = 54

We are told that 6 is two-fifths of the brownies. So we can figure it out as such:

[tex]\frac{6}{x} = \frac{2}{5}[/tex]

Cross multiply

6 * 5 = x * 2

30 = 2x

Divide both sides of the equal sign by 2 to get x by itself

[tex]\frac{30}{2} =\frac{2x}{2}[/tex]

15 = x

15/5 = 3. Every third piece is 1/5 of the pan.

One of the interior angles of the triangle, angle y is equal to 67° and the exterior angle x is equal to 113°.

The interior angles of a triangle have a total sum of 180°.

Considering the triangle with interior angles: y, 51°, and 62° we have that;

y + 51° + 62° = 180°

y + 113° = 180°

y + 113° - 113° = 180° - 113° {subtract 113° from both sides}

y = 67°

the exterior angle x and the angle y lie on a straight line, so they sum up to 180°.

x + 67° = 180°

x + 67° - 67° = 180° - 67° {subtract 67° from both sides}

x = 113°

Therefore, the interior angle y = 67° and the exterior angle x = 113°.

Step-by-step explanation:

since AD is an altitude (height) of ABC, the angle at D must be 90° (that is the definition of an altitude or height).

so,

90 = x² + 6x + 18

72 = x² + 6x

0 = x² + 6x - 72

the general solution to such a quadratic equation

ax² + bx + c = 0

is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = (-6 ± sqrt(6² - 4×1×-72))/(2×1) =

= (-6 ± sqrt(36 + 288))/2 = (-6 ± sqrt(324))/2 =

= (-6 ± 18)/2 = -3 ± 9

x1 = -3 + 9 = 6

x2 = -3 - 9 = -12

so, the 2 solutions are

x = 6

a) The percentage reduction in the price of the television each time is as follows:

b) The absolute change after the two reductions amounting to $100 is that the price of the television is now $380.

c) The overall percentage decrease in the price of the television is 20.83%.

The percentage is the ratio.

The percentage is computed as the quotient of the smaller value (numerator) over the larger value (denominator), between two values.

Percentages are depicted using the percentage sign (%) to show that the value is expressed over 100.

Price of the television = $480

First price reduction = $50

New price after the first price reduction = $430 ($480 - $50)

Percentage reduction in price = 10.42% ($50/$480 x 100)

Second price reduction = $50

New price after the second price reduction = $380 ($430 - $50)

Percentage reduction in price = 11.63% ($50/$430 x 100)

Overall percentage decrease = 20.83% ($100/$480 x 100)

Thus, overall, the price of this television decreased by 20.83 percent.

A circle is formed.

Step-by-step explanation:

When a plane, parallel to the base of a cone, slices a cone, a circle is formed

and for proof:

To find the domain of the expression 24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x)), we need to consider the values of x for which the expression is defined.

First, we need to consider the square root term, sqrt(5x^2-8x). The square root of a number is only defined for nonnegative values, so we need to find the values of x for which 5x^2-8x is nonnegative. We can do this by setting 5x^2-8x equal to 0 and solving for x:

5x^2-8x=0

5x(x-8)=0

We can see that x=0 and x=8 are the solutions to this equation. Since the square root of a negative number is not defined, the expression 24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x)) is only defined for x values that are greater than or equal to 0 and less than or equal to 8. This means that the domain of the expression is x ∈ [0, 8].

To solve the equation 24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x)), we can start by isolating one of the exponential terms on one side of the equation. Let's isolate the term 2^(sqrt(5x^2-8x)):

24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x))

22^(2sqrt(5x^2-8x)+1)=332^(sqrt(5x^2-8x))

2^(2sqrt(5x^2-8x)+1)=16.52^(sqrt(5x^2-8x))

2sqrt(5x^2-8x)+1=4.5+sqrt(5x^2-8x)

sqrt(5x^2-8x)=3.5

5x^2-8x=12.25

5x^2-8x-12.25=0

We can use the quadratic formula to solve this equation for x:

x = (-(-8) ± sqrt((-8)^2 - 45(-12.25))) / (2*5)

x = (8 ± sqrt(64 + 97)) / 10

x = (8 ± sqrt(161)) / 10

x = (8 ± sqrt(289)) / 10

x = (8 ± 17) / 10

x = -9/10 or 25/10

Since x must be greater than or equal to 0 and less than or equal to 8, the only solution that is within the domain of the expression is x=25/10, or x=2.5.

Therefore, the solution to the equation 24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x)) is x=2.5.

what do you mean by domain of a function?

The domain of a function is the set of all input values for which the function is defined. In other words, it is the set of all values that can be plugged into the function as an argument, or input, and produce a valid output

For example, consider the function f(x) = x^2. The domain of this function is all real numbers, since the function is defined for any value of x. However, some functions may not be defined for certain values of x. For example, the function g(x) = 1/x is not defined for x=0 because division by zero is not allowed. In this case, the domain of the function g(x) would be all real numbers except for x=0.

The second inequality, y < (3/2)x² + 9x -21/2, is less than the quadratic function with zero -7 and 1 and includes the point (2, 27/2).

The equation of the form ax² + bx +c is known as a quadratic equation.

Given that, the zeros of the quadratic function are -7 and 1 and include the point (2,27/2).

Substitute x = 1 into the given inequality to check whether any of them becomes less than 0 or not:

From the first inequality:

y < -3/2 + 9 + 21/2

y < 18

From the second inequality:

y < 3/2 + 9 -21/2

y < 0

Since the inequality is less than 0, it is also less than the quadratic function at x = 1.

Similarly, checking the third inequality also gives y < 0, but the fourth doesn't.

Now, from the second and the third inequality, check which one is less than 27/2 for x = 2:

From the second inequality:

y < 6 + 18 -21/2

y < 27/2

From the third inequality:

y < -6-9+21/2

y < -27/2

Since the second inequality, y < (3/2)x² + 9x -21/2, is less than 0 at x =1 and less than 27/2 at x=2, it is also less than the quadratic function whose zeros are -7 and 1 and includes the point (2,27/2).

Hence, the second inequality, y < (3/2)x² + 9x -21/2, is less than the quadratic function with zero -7 and 1 and includes the point (2, 27/2).

Consider the provided information,

Andy walked [tex]2\frac{3}{4}[/tex]  mi at a constant speed of [tex]2\frac{1}{2}[/tex] mi/h.

As we know

       Time = distance/speed

Therefore, Beth takes 1.33 hours.

Cindy walked for 1 h and 24 min at a constant speed of 1[tex]\frac{1}{4}[/tex] mi/h.

   1  hour 24 min   =  1 + 24/60   = 1.4 hours
