Number 12 I don’t get it y’all know ?

b) No, it is not

c) x + 1 is a factor

To determine if 10 is a function, we substitute x with 10 in the function:

No, it isn't a . This is because f(10) is not equal to zero, it is not a zero o. It has a remanider of 396.

c) Using synthetic division:

for x + 1: to be a factor, x = -1

+1 1 0

The last number is equal to zero. This indicates the remainder is zero.

Hence, x + 1 is a factor of the function f(x)

Step-by-step explanation:

The price per ticket, excluding the convenience charge, is  $65.

the rush delivery is given as $15.

The total cost of the tickets is said to be put at $352.50

Then the value that we would have for the the 5 tickets wpould be 352.50 - 15 = $337.50.

There is the convenience charge of $2.50 per ticket. This charge is excluded from the convenience charge that is to be paid.

Hence you would have to make the payment of

337.50 - 5*2.50

= 325.

Next we are to solve for the price of the ticket whioch is independent of the convenience charge

= 325 / 5

= $65

Hence the price per ticket is given as 65 dollars

The warmest recorded temperature is 214°F higher than the coldest temperature.

Since the sign of the two numbers are same, their final values will be added and the result will have the same signs as the two numbers (or the one with the greater absolute value). This is called the multiplicative property.

Expression for difference between the two temperatures is,

= 134−(−80)

By applying the multiplicative property of negative sign, we get

=134+80

= 214°F

Therefore, we conclude that the warmest recorded temperature is 214°F  higher than the coldest temperature.

The percentage that 7.64% gain experienced you if sold your shares, your account showed $4680 for a total gain of $357.50.

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Saima obtained a score of 57% on her exam, that corresponds to 67 out of 100. It is expressed as 57/100 in fractional form and as 57:100 in ratio form.

Given that when you sold your shares, your account showed $4680.00 ($72.00 × 65 shares)

For a total gain of $357.50 ($4680.00 – $4322.50).

Let the percentage gain you experienced be x %

As per the given data, the solution would be as:

⇒ x% of 357.50 = 4680.00

x%  is expressed as x/100 in fractional form

⇒ (x/100)(357.50) = 4680.00

⇒ x = 357.50/4680.00 × 100

⇒ x = 7.64%

Therefore, the percentage that 7.64% gain experienced you.

We have to write the equation of the line that pass through (4,-5) and (2,0).

We can calculate the slope as:

We can then write the slope-point form of the equation as:

Answer: y=-2.5x+5

An equation of the line containing the given point and parallel to the given line is y = 2x - 19.

In Mathematics, two (2) lines are considered to be parallel if their slopes are the same (equal) and they've different y-intercepts. This ultimately implies that, two (2) lines are parallel under the following conditions:

m₁ = m₂

Note: m is the slope.

Mathematically, the point-slope form of a line is given by this equation:

y - y₁ = m(x - x₁)

Where:

Given the following equation:

2x - 56 = 3     ⇒ m₁ = 2

Therefore, m₁ = m₂ = 2.

At point (8, -3), we have:

y - y₁ = m(x - x₁)

y - (-3) = 2(x - 8)

y + 3 = 2(x - 8)

y + 3 = 2x - 16

y = 2x - 16 - 3

y = 2x - 19

The person is therefore using more water for bathing than for showering, according to the conclusion.

Half of the tub's total water is consumed while taking a bath.

Water used divided by volume equals

[tex]\frac{volume}{2}[/tex]

= [tex]\frac{(5)(3)(2.8)}{2}[/tex]

=21 cubic feet.

The following will provide the total amount of water utilized while having a shower:

Total water Equals rate ×time

Equations are logical assertions in mathematics that have two algebraic expressions on either side of an equals (=) sign. The expression on the left and the expression on the right are shown to be equal in reference to one another. LHS = RHS (left hand side = right hand side) appears in all mathematical equations. You can solve equations to determine an unknown variable's value, which corresponds to an unknown quantity. It is not an equation if there is no "equal to" sign in the statement. It shall be taken into account as an expression.

To find the horizontal tangent line, we have to conduct the first derivative test. The first derivative test sets the derivative of the function equal to 0.

Let's start out with finding the derivative of the function:

It seems like we will have to use Quotient Rule.

Now we can use basic derivative rules and properties to find the final derivative:

Setting the derivative equal to 0, we can begin the first derivative test:

We can simplify the derivative before solving (expand and combine like terms):

From here, we need to determine our values of x that will make the derivative equal to 0 or undefined. In this case, since we are not trying to find relative maxima or minima, we just need to find where the entire derivative is equal to 0. We can simply just graph the numerator and find its roots:

We can see that the values of x will be -21.0416 and 3.04159 will be the values that make the derivative equal to 0.

Also recall what the derivative is. The derivative is the slope of the tangent line. In order to find the horizontal tangent line, we know that horizontal tangent lines' slope is equal to 0.

Therefore, we can use either value of x to now find our equation.

Recall what the point-slope form of a line is:

Since we know that the derivative slope must equal 0, then we know that m = 0. We now need to find a point (x, y). Substitute one of the x values into the original equation to find an actual point on the function (remember not to round intermediate values on your calculator!):

Now we have a point (x, y) (I will put it in the actual radical form here):

Substitute our variables into point-slope form:

Simplify and rewrite to obtain our final answer:

The number of large cups that would contain the same amount as 10 1/2 small cups is 6.

From the information, it was stated that we should find the number of large cups that would contain the same amount as 10 1/2 small cups if a large cup holds 1 3/4 times the quantity of liquid that's in a small cup.

This simply means that we have to divide the values that are given. This will be illustrated as:
