The domain of a function is the set of x values for which it is defined. The correct option is D.

The domain of a function is the set of x values for which it is defined, whereas the range is the set of y values for which it is defined.

To find the domain of the function it needed to be simplified. Therefore, the function can be rewritten as,

[tex]f(x) = \dfrac{3x}{4x^2-4}\\\\f(x) = \dfrac{3x}{4(x^2-1)}[/tex]

As it can be seen that for the fraction of the value of x is kept -1 or 1, then the denominator of the function will become zero, which is undefined.

Hence, the domain of the given function is all real numbers except x = –1 and x = 1.

Answer:

5

Step-by-step explanation:

The value of z in the equation -0.25z = -1.25 is simplified to z = 5.

To solve for z in the equation -0.25z = -1.25, we need to isolate z by performing the necessary operations.

We can start by dividing both sides of the equation by -0.25 to cancel out the coefficient of z:

-0.25z / -0.25 = -1.25 / -0.25

This simplifies to:

z = 5

Therefore, the value of z in the equation -0.25z = -1.25 is z = 5.

The formula for the lateral surface area of a square pyramid is [tex]a\sqrt{a^2+4h^2}[/tex], where a is the side length and h is the height of the pyramid. The first step is therefore to find the height of the pyramid. Using the pythagorean theorem, you can find that it is [tex]\sqrt{10^2-5^2}=5\sqrt{3}[/tex]. Plugging in our known values into the equation, you get [tex]10\sqrt{10^2+4(5\sqrt{3})^2}=10\sqrt{100+300}=10\cdot 20=200[/tex]. Hope this helps!

Answer:

60

Step-by-step explanation:

The initial y value can be found by setting x to 0. Anything to the power of 0 is 1, so 1.71^x when x is 0 is just 1. 60*1=60, which is the initial y value. Hope this helps!

The initial amount 'y' of the exponential function [tex]y = 60(1.71)^x[/tex] is 60. This value represents the function's y-intercept, the amount present before any exponential growth occurs.

The student has provided an exponential function and wishes to know the initial amount, which can be expressed as 'y' in the function [tex]y = 60(1.71)^x[/tex]. The initial amount when x=0 is the coefficient of the exponential term. For this function, when x equals 0,[tex](1.71)^0[/tex] is 1, since any number raised to the power of 0 is 1. Therefore, the initial amount or the y-intercept of this function is 60.

This value represents the starting quantity before any growth (or decay if the base were less than 1) has occurred in the context of the function. It is important to note that the base of the exponential function (1.71 in this case) indicates the rate of growth per unit increase of the variable x

the functions in order from least to greatest rate of change.

[tex]y=\frac{1}{2}x-2\\y=\frac{3}{4}x-10 \\y=\frac{3}{2}x+\frac{11}{2}\\y=\frac{5}{2}x+10\\[/tex]

Rate of change:

Slope of a line is the rate of change. Slope of a line tells us the steepness of the line. Equation of a line of the form y=mx+b

where m is the slope that is the rate of change.

Find the rate of change from each equation

[tex]y=\frac{3}{4}x-10\\slope =\frac{3}{4}\\\\y=\frac{3}{2}x+\frac{11}{2}\\slope =\frac{3}{2}\\\\y=\frac{1}{2}x-2\\slope =\frac{1}{2}\\\\y=\frac{5}{2}x+10\\slope =\frac{5}{2}\\[/tex]

Now we compare all the slopes

Slopes are the rate of change

[tex]slope =\frac{3}{4}\\ slope =\frac{3}{2}\\slope =\frac{1}{2}\\ slope =\frac{5}{2}\\\\\frac{1}{2} < \frac{3}{4} < \frac{3}{2} < \frac{5}{2}\\[/tex]

The function from least to greatest rate of change is

Answer:

13

Step-by-step explanation:

The equation representing the line with the slope of 5 and y-intercept of -3 is y=5x-3. This answer is derived from substituting these values into the standard line equation y=mx+b.

The equation of a line is generally given by the formula y=mx+b, where m is the slope of the line and b is the y-intercept of the line.

If the slope is 5 and the y-intercept is -3, and we plug these values into the standard formula, we get y=5x-3. Hence, the equation that describes the line with a slope of 5 and y-intercept of -3 is y=5x-3.

Answer:

The initial design fee charged per order is 40

Step-by-step explanation:

From the question, we are told that the company charges an initial design fee then additional fee for each printed t shirt

Therefore, if the cost of an order is y, we have;

y = m·x+i

Where:

i = Initial design charge

m = additional fee for each printed shirt

x = number of shirts

Comparing the above equation with the given equation we have

y        = m·x + i

M (x)  = 5·x + 40  

Hence, where M(x) = y = Charge per order, then it is noted that the coefficient of x is the additional fee per printed shirt, therefore, the initial design fee charged per order, i is equivalent to 40

Hence the initial design fee charged per order = 40.

Step-by-step explanation:

Vertical angles are the angles opposite each other when two lines cross. They are always congruent.

In this problem we have that

-----> by vertical angles

see the attached figure to better understand the problem

therefore

It is congruent to Angle A P C

The True statement about <CPB is It is supplementary to angle APC.

The correct option is (B).

In mathematics, the definition of supplementary relates to angles that combine to form a straight angle. It indicates that when two angles sum up to 180 degrees, they are said to be supplementary angles. If two angles complement one another

As, when two angles that when added together equal 180 degrees is Supplementary Angle.

From the figure if we add <CPB and <APC forms the straight line gives the angle 180 degree.

i.e., <CPB + <APC = 180

or, <CPC= 180- <APC

So, <CPB is supplementary to angle APC.
