Answer:

Retype your question. That question made me nauseous

To solve for x in the equation 4x3 = -5x - 21, we can follow these steps:

1. Move all the terms containing x to one side of the equation, and move the constant term to the other side. We can do this by adding 5x to both sides and then adding 21 to both sides:

   4x3 + 5x = -21

2. Factor out x from the left-hand side of the equation:

   x(4x2 + 5) = -21

3. Divide both sides by (4x2 + 5):

   x = -21 / (4x2 + 5)

So the solution for x is x = -21 / (4x2 + 5). Note that this is a rational function, which means that the value of x depends on the value of the variable x. This equation has no real solutions because the denominator is always positive, and the numerator is negative.

Answer:

Mark

Step-by-step explanation:

because when x = 0; y = 1

x=1; y=4

and those points are on the solid line graph.

The thought of Mark is correct.

Exponential functions are functions where the independent variable, x is in the exponent.

Given a graph.

It has a solid line and a dotted line.

The given equation is, y = 4ˣ.

In order to find which graph shows the equation, find the points that the graph of the equation will pass through.

When x = 0, y = 4⁰ = 1

Solid graph passes through (0, 1).

Hence Mark is correct.

Answer:  \(t = \frac{2-3q}{q+4}\)

This is the same as writing  t = (2-3q)/(q+4)

The parenthesis are needed so we know to divide all of "2-3q" all over top "q+4".

==================================================

Work Shown:

\(q = \frac{2-4t}{t+3}\\\\\\q(t+3) = 2-4t\\\\\\tq+3q = 2-4t\\\\\\tq+4t = 2-3q\\\\\\t(q+4) = 2-3q\\\\\\t = \frac{2-3q}{q+4}\\\\\\\)

To avoid a division by zero error, we need to have \(q \ne -4\)

Also notice how \(t = -3\) isn't possible for similar reasoning (refer to the first equation at the top).

\((\stackrel{x_1}{8}~,~\stackrel{y_1}{-16})\qquad (\stackrel{x_2}{1}~,~\stackrel{y_2}{5}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{5}-\stackrel{y1}{(-16)}}}{\underset{\textit{\large run}} {\underset{x_2}{1}-\underset{x_1}{8}}} \implies \cfrac{5 +16}{-7} \implies \cfrac{ 21 }{ -7 } \implies - 3\)

\(\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-16)}=\stackrel{m}{- 3}(x-\stackrel{x_1}{8}) \implies y +16 = - 3 ( x -8) \\\\\\ y+16=-3x+24\implies {\Large \begin{array}{llll} y=-3x+8 \end{array}}\)

Answer:

Number of 10 cents = 18

Number of  20 cents = 10

Step-by-step explanation:

Let number of 10 cents be = x

Let number 20 cents be = y

Total number of coins = x + y = 28  -------- ( 1 )

Total amount in the box = 0.10 x + 0.20y = 3.80 ---------- ( 2 )

Solve the equations to find x and y

( 1 ) => x + y = 28

         x = 28 - y

Substitute x in ( 2 )

( 2 ) => 0.10(28 - y) + 0.20y = 3.80

          2.80 - 0.10y + 0.20y = 3.80

            0.10 y = 3.80 - 2.80

            0.10 y = 1.00

                \(y = \frac{1}{0.10} = 10\)

                y = 10

Substitute y in ( 1 ) => x + y = 28

                                x + 10 = 28

                                x = 28 - 10

                                x = 18

(-8 - 0)/(-4 - 8)= -8/-12 = 2/3

The slope of the line that passes through the points (8, 0) and (-4, -8) exists at 0.66667.

The slope or gradient between two points in the Cartesian coordinate system. The slope exists the amount of slant a line retains and can maintain a positive, negative, zero, or undefined value.

Using the slope formula \((y_2 - y_1)/(x_2 - x_1)\)

\(x_1 = 8, y_1 = 0\) and \(x_2 = -4 , y_2= -8\)

slope \(= (y_2 - y_1)/(x_2 - x_1)\)

= ((-8) - 0) / ((-4) - (8))

= (-8) / (-12) = (-2) / (-3)

= 0.66667

Therefore, the slope of the line that passes through the points (8, 0) and (-4, -8) exists at 0.66667.

The rate at which the depth of the liquid is increasing when it reaches one-third of the height of the bowl is (7/3)π cm³/s.

To ascertain the rate at which the liquid's depth rises, let's find the derivative of the depth function with respect to time.

Let;

The rate of change of the volume of the liquid with respect to time is constant and equal to 7π cm³/s.

To determine the height of the bowl, we can evaluate the curve y = [-4 / (8 - x)] - 1 when x = 4 and y = 7.6 and then find the absolute difference between the values.

h = |[-4 / (8 - 4)] - 1 - [-4 / (8 - 7.6)] - 1|

Let's calculate the rate at which the depth rises when it reaches one-third of the bowl's height.

D = depth of bowl

Using this relationship from the question given;

D = (1/3) * h

In order to determine the rate at which D will change with respect to time, let's differentiate both sides of the equation.

dD/dt = (1/3) * dh/dt

Since dh/dt is the rate at which the depth of the liquid is changing, which is constant and equal to 7π cm³/s, we can substitute it into the equation:

dD/dt = (1/3) * (7π)

Simplifying, we have:

dD/dt = (7/3)π cm³/s

5 hours × 65 km/hour = 325 km

Total distance = 40+45+50+35+55+325 = 550 km

Total distance covered by the car in total journey including the distance covered with an average speed of 65km/hr is 600km.

Given, Average speed of car 65km/hr .

Distance covered in first five hours = 40 km + 45 km + 50 km + 35 km + 55 km

= 235km

Using speed, time, distance formula.

Distance = Speed × Time

Average speed  65km/hr for 5 hours.

Distance covered in 5 hours = 65km/hr × 5hours

= 65 × 5

= 325 km

Total distance covered in 10 hours = 325km + 235km
