Answer:

[tex]\frac{10a + 6}{-a^2 + 1}[/tex] is undefined at a = 1

Step-by-step explanation:

Required

Which is undefined at a = 1

An expression is undefined when its denonimator equals 0.

So, we have to test the denominator of each.

(A): 7a + 7

This gives:

[tex]= 7(1) + 7[/tex]

[tex]= 7 + 7[/tex]

[tex]= 14[/tex]

(B): 5a - 10

This gives:

[tex]= 5(1) - 10[/tex]

[tex]= 5- 10[/tex]

[tex]= -5[/tex]

(C) -a² + 1

This gives

[tex]-(1^2) + 1[/tex]

[tex]= -1 + 1[/tex]

[tex]=0[/tex]

(D) 3a²

This gives:

[tex]= 3(1)^2[/tex]

[tex]= 3 * 1[/tex]

[tex]= 3[/tex]

Notice that only (C) equals 0.

Hence:

[tex]\frac{10a + 6}{-a^2 + 1}[/tex] is undefined at a = 1

Answer:

C

The easiest way to get the maximum r value is to draw a line from the origin at angle θ until it hits the semicircle, and a line from there to (2,0)(2,0). Then you can see in the diagram a right-angled triangle (because the angle in a semicircle is a right angle) with hypotenuse 22, and so we get max=2cosrmax=2cos⁡θ.

The ranking of the given  numbers from least to greatest is;

5, 5²⁸/₄₀, 5⁴/₅

We are given the numbers as;

5, 5¹²/₁₅, 5²⁸/₄₀

Now, let us breakdown the mixed fractions for easier comparison with all numbers;

5¹²/₁₅ can be broken down into 5⁴/₅

For the second mixed fraction which is 5²⁸/₄₀;

5²⁸/₄₀ can be broken down into 5⁷/₁₀

Now, 7/10 is lesser than 4/5 and so 5⁴/₅  is greater than 5²⁸/₄₀. Thus, ranking of all numbers from least to greatest is; 5, 5²⁸/₄₀, 5⁴/₅

The equation of line that passes through the given points is x-5y=47.

Given that the line that passes through ( -3,-10) and (7,-8).

The standard form of the line equation is ax+by+c = 0. Here a, b are the coefficients, x, y are the variables and c are the constant terms. It is a quadratic equation, of the variables x and y. The values ​​of x and y represent the coordinates of the point on the line in the coordinate plane.

Firstly, we will find the slope of equation of line by using the given points.

(x₁,y₁)=(-3,-10) and (x₂,y₂)=(7,-8).

m=(y₂-y₁)/(x₂-x₁)

Now, we substitute the values, we get

m=(-8-(-10))/(7-(-3))

m=(-8+10)/(7+3)

m=2/10

m=1/5

Further, we will find the equation of line using the formula y-y₁=m(x-x₁).

Now, we will substitute the values , we get

y-(-10)=(1/5)(x-(-3))

y+10=(1/5)(x+3)

Further, we will multiply both sides by 5, we get

5(y+10)=x+3

5y+50=x+3

5y+50-50=x+3-50

5y=x-47

x-5y=47

Hence, the equation of line that passes through ( -3,-10) and (7,-8) is x-5y=47.

The absolute function is having its turning point at the coordinate ( 2,3).

It is required to find the turning point of the graph  .

Absolute value describes the distance from zero that a number is on the number line, without considering direction. The absolute value of a number is never negative.

Given:

The absolute function is

f(x) = |x-2| +3.

We have to find the turning point of the graph of f(x)=|x−2|+3.

According to given question we have,

When we plot the graph of the absolute function f(x) = |x-2| +3 it will give two straight lines the first line is on the left side and the second line is on the right side. The graph of the function changes its position at the coordinate ( 2,3).

Therefore, the absolute function is having its turning point at the coordinate ( 2,3).

Answer:

9

Step-by-step explanation:

The value of y at x =15 is 9.

Two variables are said to be in Direct Variation when increasing one variable the other also increases.

The direct variation is represented by

y ∝ x

y = kx

where k is the proportionality constant

the value of y =12 , x = 20

12 = k * 20

12/20 = k

k = 0.6

The equation becomes

y = 0.6 x

The value of y at x = 15 is

y = 0.6 * 15

y =9

Therefore, the value of y at x =15 is 9.

The simplified trigonometric expression is given as follows:

The expression is given by:

[tex]\frac{\cos{\theta}}{1 + \csc{\theta}} \times \frac{1 - \csc{\theta}}{1 - \csc{\theta}}[/tex]

Applying the subtraction of perfect squares at the denominator, we have that the expression is given by:

[tex]\frac{\cos{\theta}(1 - \csc{\theta})}{1 - \csc^2{\theta}}[/tex]

Applying an identity, we have that:

[tex]1 - \csc^2{\theta} = -\cot^2{\theta}[/tex]

Hence the expression is:

[tex]-\frac{\cos{\theta}(1 - \csc{\theta})}{\cot^2{\theta}}[/tex]

cot = cos/sin, hence:

[tex]-\frac{sin^2{\theta}(1 - \csc{\theta})}{\cos{\theta}}[/tex]

tan = sin/cos, hence the simplified expression is:

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

Explanation:

The mean of all ten numbers is 22.

This tells us the sum of those ten numbers is 10*22 = 220

Recall that

mean = (sum of items)/(number of items)

We take this process in reverse to find the sum.

In other words:

sum = (mean)*(number of items)

--------------

Now remove the elements {8,12,21,23} to get a new sum of:

220-8-12-21-23 = 156

Divide that smaller sum over 6 since removing 4 elements leaves us with 10-4 = 6 left over.

new mean = (new smaller sum)/(number of items)

new mean = (156)/(6)

new mean = 26

Answer:

The daily rate that maximizes the revenue is $40 and the maximum revenue is $9600

Step-by-step explanation:

Given

[tex]Rooms = 240[/tex]

[tex]Price= \$40[/tex]

[tex]Increment = \$2[/tex]

First, we calculate the revenue.

[tex]Revenue (r) = Price (p) * Number\ of\ Rooms(n)[/tex]

[tex]r = p*n[/tex]

Let x be the change in rate.

i.e.

For every 2x increment in price (p) i.e. p + 2x

There will be 4 fewer rooms (n) i.e. n - 4x

So, the revenue is updated as:

[tex]r = (p + 2x) * (n - 4x)[/tex]

[tex]Price = 40[/tex]

So:

[tex]r = (40 + 2x) * (n - 4x)[/tex]

[tex]Rooms = 240[/tex]

So:

[tex]r = (40 + 2x) * (240 - 4x)[/tex]

Expand

[tex]r = 40 * 240 - 40 * 4x + 2x * 240 - 2x*4x[/tex]

[tex]r = 9600 - 160x + 480x - 8x^2[/tex]

Reorder

[tex]r = -8x^2 - 160x + 480x + 9600[/tex]

[tex]r = -8x^2 +320x + 9600[/tex]

The maximum of a function is calculated as:

[tex]Max = -\frac{b}{2a}[/tex]

In: [tex]r = -8x^2 +320x + 9600[/tex]

[tex]a = -8[/tex]   [tex]b = 320[/tex]    [tex]c = 9600[/tex]

So:

[tex]Max = -\frac{b}{2a}[/tex]

[tex]Max = -\frac{320}{-8}[/tex]

[tex]Max = \frac{320}{8}[/tex]

[tex]Max = 40[/tex]

To get the maximum revenue;

Substitute 40 for x in [tex]r = -8x^2 +320x + 9600[/tex]

[tex]r = -8(40)^2 + 320 * 40 + 9600[/tex]

[tex]r = 9600[/tex]

The daily rate that maximizes the revenue is $40 and the maximum revenue is $9600

The missing piece of information in the proof is that m∠DOA and m∠BOC are vertical opposite angles.

We want to prove that m∠BOC = 90°.

We are given that m∠AOB is a right angle triangle. Thus;

m∠BOC must also be equal to 90°

Now, since m∠BOC and m∠AOB are right angles, then it means that we must equally say that m∠DOA and m∠BOC are vertical opposite angles and they are as such equal.

Thus, the missing piece of information in the proof is that m∠DOA and m∠BOC are vertical opposite angles.
