The mathematical expression that shows the number of math problem left for Ernest is 16-p

Linear expressions are expression that it's highest power in of it's variable is 1. Linear expression can have more than one variables.

Some of the examples of linear equations are 2x – 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x – y + z = 3.

Ernest has 16 math problem , he has solved p out of it.

To actually know the remaining math problem left, we subtract the number he has done from the number of original problem

This means the number r of problem left = 16-p

therefore the expression is 16-p

Torr and mmHg are two units of pressure that are often used interchangeably. In fact, 1 mmHg is equal to 1 torr, which means that they are equivalent units of measurement.

To convert torr to mmHg, you can simply multiply the pressure value in torr by 1, since 1 torr is equivalent to 1 mmHg. For example, if you have a pressure of 760 torr, you can convert it to mmHg as follows:

760 torr x 1 mmHg/torr = 760 mmHg

Therefore, 760 torr is equivalent to 760 mmHg. Alternatively, you can also convert mmHg to torr by dividing the pressure value in mmHg by 1. For example, if you have a pressure of 760 mmHg, you can convert it to torr as follows:

760 mmHg ÷ 1 mmHg/torr = 760 torr

Therefore, 760 mmHg is equivalent to 760 torr.

Answer:

              An equation to represent the given geometric sequence would be [tex]a(x)=5*3^{x-1}[/tex], and a(8) of the geometric sequence will be 10,935.

Step-by-step explanation:

              In order to write an equation for a geometric sequence, first we must analyze the sequence to find its starting value and its constant ratio. The starting value is simply the first term in the sequence, which is 5. As for the constant ratio, it is the rate of change that the equation uses. In this sequence, the constant ratio is 3. Now, we can write out an equation for this geometric sequence.

              We know the first term of the sequence is 5, and the common ratio is 3, so we can write out a function for the geometric sequence, which will be [tex]a(n)=5*3^{n-1}[/tex]. NOTE that the exponential power is n - 1, and not n. This is because the first term of the sequence is 5, and not the "0th" term, therefore we must subtract 1 from n (the term number) to have the right sequence.

              Lastly, we can use the equation [tex]a(n)=5*3^{n-1}[/tex] to find the 8th term of the sequence by replacing n with 8. So [tex]a(x)=5*3^{n-1}[/tex] would become [tex]a(8)=5*3^{8-1}[/tex], and you will get [tex]a(8)=5*3^{8-1}[/tex] ⇒ [tex]a(8)=5*3^{7}[/tex] ⇒ [tex]a(8)=5*2187[/tex] ⇒ [tex]a(8)=10,935[/tex]. Therefore, the equation for the nth term of the geometric sequence would be [tex]a(n)=5*3^{n-1}[/tex], and the 8th term of the sequence is 10,935.

If the price elasticity of demand is equal to 0.02/0.1, then the demand for apples is inelastic and if the price elasticity of demand is equal to 0.2/5, then the demand for apples is elastic.

The price elasticity of demand is calculated using the midpoint method with formula:

Price Elasticity of Demand = (Percent Change in Quantity Demanded) / (Percent Change in Price)

The value of the price elasticity of demand tells us whether the demand for a product is elastic (sensitive to price changes), inelastic (insensitive to price changes), or unitary elastic (neither elastic nor inelastic). A value of price elasticity of demand greater than 1 indicates that the demand for the product is elastic, meaning that a small change in price leads to a large change in the quantity demanded. A value of price elasticity of demand less than 1 indicates that the demand for the product is inelastic, meaning that a small change in price leads to a small change in the quantity demanded.

If the price elasticity of demand is equal to 0.02/0.1, then the demand for apples is inelastic between points X and Y, meaning that a small change in price leads to a small change in the quantity demanded. If the price elasticity of demand is equal to 0.2/5, then the demand for apples is elastic between points X and Y, meaning that a small change in price leads to a large change in the quantity demanded.

Option 2 Is Correct

Step-by-step explanation:

The following statements are true about the function and its graph:

The graph of the function is a parabola.

The graph contains the point (0, 0).

The graph does not contain the point (20, -8).

Option 1 is true because the function is a quadratic function, and all quadratic functions have a parabolic graph.

Option 2 is true because the y-intercept of the function is (0,0).

Option 3 is false because the function opens upwards

The values of x make the statement true are x = 9 X = -9.5 x = -9 and x = -10

From the question, we have the following parameters that can be used in our computation:

x-9.5 = a negative number

Using the above as a guide, we have the following:

x - 9.5 < 0

A flat shape with 4 straight sides that are all equal length. Also opposite sides are parallel and opposite angles are equal. It is a type of parallelogram.

Given is a rhombus DEFG, we need to find the measures of the numbered angles,

We know that, diagonals of a rhombus bisect each other at right angle, and also bisects the vertex angles,

Also, the opposite angles are equal,

Therefore,

m ∠ 1 = m ∠ 2 = m ∠ 4 = 27°

m ∠ 3 = 90°

m ∠ 5 = m ∠ 6 = 90° - m ∠ 1

m ∠ 5 = m ∠ 6 = 90° - 27° = 63°

m ∠ 5 = m ∠ 6 = 63°

Hence, the measures of the numbered angles in rhombus DEFG are m ∠ 1 = m ∠ 2 = m ∠ 4 = 27°, m ∠ 3 = 90° and m ∠ 5 = m ∠ 6 = 63°

Answer: The solution of the system of equations is (x, y) = (-1, -2).

Step-by-step explanation:

We can solve this system of equations by using either elimination or substitution method. Here, we'll use elimination:

Adding the two equations, we get:

(3x + 7y) + (-3x + 9y) = -17 - 15

Simplifying the left side and right side:

16y = -32

Dividing both sides by 16:

y = -2

Now we can substitute y = -2 into either of the original equations and solve for x. Let's use the first equation:

3x + 7(-2) = -17

Simplifying:

3x - 14 = -17

Adding 14 to both sides:

3x = -3

Dividing both sides by 3:

x = -1

The bearing of the bank from the swimming pool is 42 degrees south of west.

What is temperature ?

Temperature is a measure of how hot or cold something is. More specifically, it is a measure of the average kinetic energy of the particles that make up a substance. When the particles in a substance move faster, their kinetic energy increases, and the temperature of the substance goes up.

Temperature is usually measured in degrees Celsius (°C) or degrees Fahrenheit (°F), although in scientific contexts, the International System of Units (SI) unit of temperature is the kelvin (K). The Celsius scale sets the freezing point of water at 0°C and the boiling point at 100°C, while the Fahrenheit scale sets the freezing point of water at 32°F and the boiling point at 212°F. The kelvin scale sets the zero point at absolute zero (-273.15°C or -459.67°F), the theoretical temperature at which all molecular motion ceases.

According to given condition:

The bearing of the swimming pool from the bank is 138 degrees.

The bearing is the angle measured clockwise from the north direction.

Therefore, to find the bearing of the bank from the swimming pool, we need to add 180 degrees to the given bearing of 138 degrees and then subtract 360 degrees (a full circle) to get the bearing within the range of 0 to 360 degrees.

So,

Bearing of bank from swimming pool = (138 + 180 - 360) degrees = -42 degrees

Therefore, the bearing of the bank from the swimming pool is 42 degrees south of west.
