Answer:

The domain of exponential parent function is all real values and range is real positive numbers [tex]y>0[/tex].

Step-by-step explanation:

We are asked to find the domain and range of exponential parent function.

We know that an exponential parent function is in form [tex]f(x)=b^x[/tex], where b is the base of function.

We can see from parent exponential function that as x approaches to very large values of x, the value of y increases with no bounds.

As x approaches negative infinity, y approaches to zero.

We know that the domain of a parent exponential function is all real values of x that is [tex](-\infty,\infty)[/tex] in interval notation.

The range of a parent exponential function is positive real numbers that is [tex]y>0[/tex].

Answer:

[tex]A=5, B=0,C=3[/tex]

Step-by-step explanation:

The partial fraction decomposition is given as:

[tex]\frac{5x^2+3x+54}{(x+3)(x^2+9)} \equiv \frac{A}{x+3}+\frac{Bx+C}{x^2+9}[/tex]

We collect LCD on the RHS to obtain;

[tex]\frac{5x^2+3x+54}{(x+3)(x^2+9)} \equiv \frac{A(x^2+9)+(x+3)(Bx+C)}{(x+3)(x^2+9)}[/tex]

We expand the parenthesis in the numerator of the fraction on the RHS.

[tex]\frac{5x^2+3x+54}{(x+3)(x^2+9)} \equiv \frac{Ax^2+9A+Bx^2+(3B+C)x+3C}{(x+3)(x^2+9)}[/tex]

This implies that:

[tex]\frac{5x^2+3x+54}{(x+3)(x^2+9)} \equiv \frac{(A+B)x^2+(3B+C)x+3C+9A}{(x+3)(x^2+9)}[/tex]

This is now an identity. Since the denominators are equal, the numerators must also be equal.

[tex]5x^2+3x+54=(A+B)x^2+(3B+C)x+3C+9A[/tex]

We compare coefficients of the quadratic terms to get:

[tex]A+B=5\implies B=5-A...(1)[/tex]

Also the coefficients of the linear terms will give us:

[tex]3B+C=3...(2)[/tex]

The constant terms also gives us;

[tex]3C+9A=54...(3)[/tex]

Put equation (1) in to equations (2) and (3).

[tex]3(5-A)+C=3\implies C=3A-12...(4)[/tex]

[tex]3C+9A=54...(5)[/tex]

Put equation (4) into (5).

[tex]3(3A-12)+9A=54[/tex]

[tex]9A-36+9A=54[/tex]

[tex]9A+9A=54+36[/tex]

[tex]18A=90[/tex]

[tex]A=\frac{90}{18} =5[/tex]

Do backward substitution to get:

[tex]C=3(5)-12=3[/tex]

[tex]B=5-5=0[/tex]

[tex]\therefore A=5, B=0,C=3[/tex]

The constants A, B, and C in the partial fraction decomposition are determined to be A = 5, B = 0, and C = 3.

To find the values of A, B, and C in the partial fraction decomposition of the rational function

Step-by-step explanation:

7(1–k)

= 1(7) -k(7)  -------------> distributive property

= 7–7k

Answer:

You MUST use parentheses around denominator 8+x, or ANY denominator that consist of more than a single number of variable. 

Also, don't use lower case and upper case interchangeably. 

In algebra, x and X are different, as are y and Y. 

f(x) = y = 3x/(8+x) 

Switch x and y, solve for y: 

x = 3y/(8+y) 

x(8+y) = 3y 

8x+xy = 3y 

8x = 3y−xy 

8x = y(3−x) 

y = f⁻¹(x) = 8x/(3−x)

Answer:

Option C. approaches but does not cross.

Step-by-step explanation:

In Maths, an asymptote is a line that the graph (a drawing that shows two sets of related amounts) of a function (e.g. x=1/x) approaches but does not cross (or intersect). The image below illustrates such concept.

Answer:    C. Approaches but does not cross

Step-by-step explanation:  Basically an asymptote is a line that approaches a given curve which is graph of a function, but it never touches, cross or intersect in any finite. Asymptote can be any line, horizontal, vertical, inclined, which approaches the function graph. Theoretically, according to mathematical principles,  the function graph line is approaching to a asymptote at infinity, and therefore the asymptotes are suitable as the type of guide to complete the graph of the function.

Answer:

Undefined

Step-by-step explanation:

You can deduce the solution in two ways: if the slope of m is zero, it is horizontal. So, n is vertical because it must be perpendicular to n. Vertical lines have undefined slope.

Alternatively, if the slope of line m is k, the slope of a perpendicular line n is -1/k. So, if k=0, you can't compute -1/0.

Answer:

-5,-4,-3

Step-by-step explanation:

Let n be an integer.

The next integer would have to be n+1.

The integer before n would have to be n-1.

So the numbers in order are n-1, n , n+1

The sum of the first 2 equals 3 times the third:

n-1     +     n                      =     3(n+1)

2n-1                                 =      3(n+1)

2n-1=3n+3

Subtract 2n on both sides

    -1=n+3

Subract 3 on both sides

    -4=n

If n=-4

then n-1=-5

and n+1=-3

So the three numbers are -5,-4,-3 .

Answer:

0.16

Step-by-step explanation:

81 is 1 standard deviation below the mean.  According to the empirical rule, 68% of data lies within 1 standard deviation of the mean; here the equivalent statement would be that half of that, or 34%, lies within 1 standard deviation below the mean.  Half of the area under the standard normal curve, less this 0.34, is the probability that the random variable is below 1 standard deviation beneath the mean.  That comes to 0.16.

On a calculator, you might enter the command normalcdf(-100,81,85,4); on my old TI-83 Plus I get 0.1587, which rounds off to 0.16.

Final answer:

The z-score of -1 corresponds to a probability of approximately 0.1587, therefore P(x < 81) is approximately 0.1587, or 15.87%.

Explanation:

To find the probability that a normally distributed random variable x is less than 81, P(x < 81), when the mean μ is 85 and the standard deviation σ is 4, we need to use the properties of the normal distribution.

First, we convert the raw score of 81 into a z-score. The formula for calculating a z-score is:

[tex]z = (x - μ) / σ[/tex]

For x = 81, the z-score would be:

z = (81 - 85) / 4

z = -1

Next, we use a standard normal distribution table, a calculator, or software to find the probability that correlates with this z-score. The table lists probabilities to the left of z-scores.

The z-score of -1 corresponds to a probability of approximately 0.1587, therefore P(x < 81) is approximately 0.1587, or 15.87%.

Answer: 317.93

Step-by-step explanation:

317.93371 when rounded off to nearest hundred, we get 317.93.

Rounding off is the method by which a decimal integer is reduced to its nearest closer value of the next number . After the decimal point, if the value is greater than 5 we increment the numerical value by 1 and if the value is less than 5 we keep the numerical value intact.

The given value is 317.93371 .

Rounding off to nearest hundred means that we will get the rounded off value up to two decimal places.

We can see that the third decimal place is 3 which means that the second decimal place of the number will be kept intact.

Rounded off value is -  317.93 .

Thus, 317.93371 when rounded off to nearest hundred, we get 317.93.

Table 3 and 4

Step-by-step explanation:

Let us understand the coordinates symmetry of the graphs of quadratic equations.

In a quadratic equation, we have a polynomial in x with degree 2. Hence the result in y or P(x) do get repeated as polynomial contains [tex]x^2[/tex] in it.

Thus by analysing the tables we see that in table 3 , y= -10 gets repeated and in table 4 , y =4 and y=-4 repeated. Hence they are the graph of a quadratic polynomial

Answer:

Step-by-step explanation:

Going to start with the sum identities

sin(x+y)=sin(x)cos(y)+sin(y)cos(x)

cos(x+y)=cos(x)cos(y)-sin(x)sin(y)

sin(x)cos(x+y)=sin(x)cos(x)cos(y)-sin(x)sin(x)sin(y)

cos(x)sin(x+y)=cos(x)sin(x)cos(y)+cos(x)sin(y)cos(x)

Now we are going to take the line there and subtract the line before it from it.

I do also notice that column 1 have cos(y)cos(x)sin(x) in common while column 2 has sin(y) in common.

cos(x)sin(x+y)-sin(x)cos(x+y)

=0+sin(y)[cos^2(x)+sin^2(x)]

=sin(y)(1)

x + y = 330

9x + 16y = 4650

Step-by-step explanation:

Given that x = children and y = adults, we can say that x + y = 330.

Since the total amount of money collect from both children and adults was $4650, we can say that 9x + 16y = 4650.

So the system that represents the situation is:

x + y = 330

9x + 16y = 4650

Answer:

Both the lines would have the same slope since they are parallel. The lines would not however have the same y-intercept.

Step-by-step explanation:

This is because in order for lines to be parallel the lines must have the same slope, otherwise they would meet at some point. They would not have the same y-intercept because if both the y-intercept and the slope were the same it would be the same line.

Answer:

Both lines are parallel, so they have the same slope. However, the y-intercepts of the lines are not the same. For the lines to be parallel, the slopes of the lines must be the same. If both the y-intercept and slope are the same, they are the same line, so they do not have the same y-intercept.

Answer:

Kate’s photo get 14 likes

Step-by-step explanation:

Let

x ----> Kate's likes

y ---> Ali's likes

we know that

y=42 likes ----> equation A

y=3x ----> equation B

Solve by substitution

Substitute equation A in equation B and solve for x

42=3x

Divide by 3 both sides

x=42/3

x=14 likes

Kate's photo got 14 likes.

The student is dealing with a basic algebra problem that involves setting up and solving an equation. To find out how many likes Kate's photo got, we can let x represent the number of likes on Kate's photo. Given that Ali's photo got 42 likes, which is three times as many as Kate's photo, we can write the equation as:

3x = 42

To find x, we divide both sides of the equation by 3:

x = 42 / 3

x = 14

Therefore, Kate's photo got 14 likes.
