Step-by-step explanation:

Answer:

Problem One: D

Problem Two: B

Step-by-step explanation:

Problem One

A and B are both wrong for the same reason. The graph for both of them will increase. Any time you raise a base greater than 1 to a power, the graph goes up. See below. The red graph is y = 12*1.1^2

The question is giving you a big hint by showing you which point to look at. When x = 1, y = 8. What will do that?

Is it 12 * 1/2 or is it 12 * 2/3

I think you will find it is 12*2/3 So the answer is D

Part B

This one is just the opposite, only now you have to figure out which graph you are getting. A is the only one that is obviously wrong. When x = 1, A will give

40* 1.5 which is 60 which is not enough.

C is too large. 40 * 3.25 = 130 so that does not describe the graph when x = 1.

So B and D are your only choices. D is still a little too big. See if you can get D to be 100 when D = 1

That leaves you with b

y = 40 * 2.25 = 90 which is just what you want.

Answer:

[tex]\cos\left(\theta\right)=\frac{\sqrt{15}}{4}[/tex]

Step-by-step explanation:

Given that [tex]\sin\left(-\theta\right)=-\frac{1}{4}[/tex] and [tex]\tan\left(\theta\right)=\frac{\sqrt{15}}{15}[/tex]

Using those values we need to find value of [tex]\cos\left(\theta\right)[/tex]

So let's begin with equation of  [tex]\tan\left(\theta\right)=\frac{\sqrt{15}}{15}[/tex] and simplify it to get value of  [tex]\cos\left(\theta\right)[/tex]

[tex]\tan\left(\theta\right)=\frac{\sqrt{15}}{15}[/tex]

[tex]\frac{\sin\left(\theta\right)}{\cos\left(\theta\right)}=\frac{\sqrt{15}}{15}[/tex]

[tex]\sin\left(\theta\right)=\frac{\sqrt{15}}{15}\cos\left(\theta\right)[/tex]

[tex]\sin\left(\theta\right)\cdot\frac{15}{\sqrt{15}}=\cos\left(\theta\right)[/tex]

[tex]\cos\left(\theta\right)=\sin\left(\theta\right)\cdot\frac{15}{\sqrt{15}}[/tex]

[tex]\cos\left(\theta\right)=-\sin\left(-\theta\right)\cdot\frac{15}{\sqrt{15}}[/tex]  {since [tex]\sin\left(-\theta\right)=-\sin\left(\theta\right)[/tex] }

[tex]\cos\left(\theta\right)=-\sin\left(-\theta\right)\cdot\sqrt{15}[/tex]

[tex]\cos\left(\theta\right)=-\left(-\frac{1}{4}\right)\cdot\sqrt{15}[/tex]

[tex]\cos\left(\theta\right)=\frac{\sqrt{15}}{4}[/tex]

Answer:

[tex]\cos \theta = \frac{\sqrt{15}}{4}[/tex]

Step-by-step explanation:

The sine function is an odd function, that is:

[tex]\sin (-\theta) = - \sin \theta[/tex]

Then,

[tex]\sin \theta = \frac{1}{4}[/tex]

The cosine function is computed by the following relation:

[tex]\cos \theta = \frac{\sin \theta}{\tan \theta}[/tex]

[tex]\cos \theta = \frac{\frac{1}{4} }{\frac{\sqrt{15}}{15} }[/tex]

[tex]\cos \theta = \frac{\frac{1}{4} }{\frac{1}{\sqrt{15}} }[/tex]

[tex]\cos \theta = \frac{\sqrt{15}}{4}[/tex]

[tex]\text{Unit rate for buffalo bills}=\frac{\$0.875}{\text{ wing}}[/tex]

Upon rounding our answer to nearest cent we will get,

[tex]\text{Unit rate for buffalo bills}=\frac{\$0.88}{\text{ wing}}[/tex]

Therefore, buffalo bills offers each wing for $0.88.

[tex]\text{Unit rate for buffalo mild wings}=\frac{\$10}{12\text{ wings}}[/tex]

[tex]\text{Unit rate for buffalo mild wings}=\frac{\$0.83333}{\text{ wing}}[/tex]

Upon rounding our answer to nearest cent we will get,  

[tex]\text{Unit rate for buffalo mild wings}=\frac{\$0.83}{\text{ wing}}[/tex]

Therefore, buffalo mild wings offers each wing for $0.83.

[tex]\text{Unit rate for wingers}=\frac{\$17}{20\text{ wings}}[/tex]

[tex]\text{Unit rate for wingers}=\frac{\$0.85}{\text{ wing}}[/tex]

Therefore, wingers offers each wing for $0.85.

We can see that buffalo mild wings offers the lowest price per wing that is $0.83 per wing.

Answer:

A/C and B/D and C/E

Step-by-step explanation:

given the order of 2 matrices

(m × n)(p × q)

For the matrices to be conformable for multiplication

The number of columns in the first must equal the number of rows in the second

That is n = p and the resulting product has order m × q

From the order of matrices given

A and C, B and D, C and E can be multiplied

The matrices that can be multiplied are A*C, C*A, B*D, and E*D, as the number of columns in the first matrix equals the number of rows in the second.

In matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix. Therefore, given the order of the matrices A = 3x2, B = 3x5, C = 2x3, D = 5x7, and E = 3x5, the possible matrix multiplications are: A*C, C*A, B*D, and E*D. For instance, you can multiply A (which is 3x2) with C (which is 2x3) because the number of columns in matrix A is equal to the number of rows in matrix C.

Answer:

225

Step-by-step explanation:

The sum total of all the angles is 7,740 degrees,

The formula for the interior angle is 180(n - 2) where n is the number of sides in the polygon

Set this equal to 7740

180 (n-2) = 7740

Divide each side by 180

 180/180 (n-2) = 7740/180

  n-2 =43

Add 2 to each side

n-2+2 = 43+2

n = 45

Each vertex hold 5 people so take n and multiply by 5

45*5 = 225

The Ferris wheel holds 225 people

Answer:

Stefan spend originally $110 and the money stefan make by selling the bicycle and helmet to jin is $22 .

Step-by-step explanation:

As given

Stefan sells jin a bicycle for $114 and a helmet for $18.

Total cost of the bicycle and helmet = $114 + $18

                                                            = $132

The total cost for jin is 120% of what stefan spent originally to buy the bike and helmet.

120% is written in the decimal form.

[tex]= \frac{120}{100}[/tex]

= 1.20

Let us assume that the Stefan spend originally for bike and helmets be x.

Than the equation becomes

1.20 × x = 132

1.20x = 132

[tex]x = \frac{132}{1.20}[/tex]

x = $110

Therefore stefan spend originally be  $110 .

Now find out how much money did he make by selling the bicycle and helmet to jin .

Money make by Stefan = Total selling cost of helmet and bicycle  - Total amount of  stefan spends for purchasing.

Money make by Stefan = 132  - 110

Money make by Stefan = $22

Therefore the money stefan make by selling the bicycle and helmet to jin is $22 .

Stefan's original expenditure for the bicycle and helmet was $110. He made a profit of $22 by selling these items to Jin.

Stefan sold the bicycle and helmet to Jin for a total of $132 ($114 + $18). We know that this amount represents 120% of what Stefan originally spent. To determine Stefan's original expenditure, we'll therefore divide the total amount he earned by 120 and then multiply by 100 (as the cost is 100% for him). So, Stefan's original expenditure would be (132/120)*100 = $110.

Now, to determine Stefan's profit, we subtract his original expenditure from the amount for which he sold the items to Jin. That is, $132 - $110 = $22. So, Stefan made a $22 profit from selling the bicycle and helmet.

Answer:

A) Infinite and f(6) does not exist

Step-by-step explanation:

The three types of discontinuities are:

1. Removable or Hole: When the left hand limit is same as right hand limit but they are not equal to the value of function at x = 6.

Graphically if there exist a hole at the point x = 6, removable discontinuity occurs. But, it is not the case in the given graph.

2. Jump: When the left hand limit is not same as right hand limit.

But graphically, we see that both left and right limit at x=6 are tending to infinity i.e. both limits are same.

3. Infinite: It occurs when there exists vertical or horizontal asymptotes between the function and both limits tend to infinity.

Graphically, we see that the function has infinite discontinuity as there exist vertical asymptote and the value of function does not exist at x = 6.

Answer:

[tex]\frac{7}{64}\approx 0.11[/tex]

Step-by-step explanation:

We have been given that there are 4 red marbles and 7 blue marbles and 5 yellow marbles in a bag. Monica will randomly pick two marbles out of the bag replacing the first marble before picking the second marble.

Since Monica will replace the first marble before picking the second marble, therefore, probability of both events will be independent and probability of occurring one event will not affect the probability of second event's occurring.          

Since the probability of two independent compound events is always the product of probabilities of both events.

[tex]P(\text{A and B})=P(A)*P(B)[/tex]

Now let us find probability of picking a red marble out of 16 (4+7+5) marbles.

[tex]P(Red)=\frac{\text{Total red marbles}}{\text{Total marbles}}[/tex]

[tex]P(Red)=\frac{4}{16}[/tex]

Probability of picking blue ball out of 16 (4+7+5) marbles:

[tex]P(Blue)=\frac{\text{Total blue marbles}}{\text{Total marbles}}[/tex]

[tex]P(Blue)=\frac{7}{16}[/tex]

Now let us find probability of Monica picking a red and then a blue marble.

[tex]P(\text{Red and Blue})=\frac{4}{16}\times \frac{7}{16}[/tex]

[tex]P(\text{Red and Blue})=\frac{1}{4}\times \frac{7}{16}[/tex]

[tex]P(\text{Red and Blue})=\frac{7}{4*16}[/tex]

[tex]P(\text{Red and Blue})=\frac{7}{64}[/tex]

[tex]P(\text{Red and Blue})=0.109375\approx 0.11[/tex]

Therefore, the probability of picking a red and then blue marble is [tex]\frac{7}{64}\approx 0.11[/tex].

The equation of the line that passes through the point (-1,5) and has a slope of -7 is y = -7x - 2. This can be determined by substituting the given values into the equation y = mx + b and solving for 'b'.

In mathematics, the equation of a line is commonly represented as y = mx + b, where 'm' represents the slope and 'b' is the y-intercept. In this equation, the slope '-7' is the rate at which 'y' changes for a unit change in 'x'. The y-intercept is the 'y' value when 'x' is zero.

It's given that the line passes through the point (-1,5). We can substitute these values into the equation to find 'b':

5 = -7(-1) + b, which simplifies to 5 = 7 + b. Therefore, 'b' equals to -2 after rearranging.

So, the equation of the line that passes through the point (-1,5) and has a slope of -7 is y = -7x - 2.

Step-by-step explanation:

so basically to add up radicals you need to make the number inside the square root the same. what you have to do to do that is find squares inside the number as a factor.

13√80=13*2√20=13*2*2√5=52√5

3√125=3*5√5=15√5

√500=10√5

so all of them have 5 in the square root so you can add them up to equal 77√5

To find the perimeter of a triangle with given radical expressions for side lengths, simplify each expression and add them up. The correct answer is D) 77√5.

The perimeter of a triangle is the sum of the lengths of all three sides. So, to find the perimeter of the triangle given the side lengths as radical expressions, we need to simplify and add them up.

The given side lengths are: 13√80 , 3√125, and √500.

Simplify each radical expression:

13√80 = 13 * √(16 * 5) = 13 * (4 * √5) = 52√5

3√125 = 3 * √(25 * 5) = 3 * (5 * √5) = 15√5

√500 = √(100 * 5) = 10√5

Now, add up the simplified radical expressions: 52√5 + 15√5 + 10√5 = (52 + 15 + 10)√5 = 77√5.

Therefore, the correct answer is D) 77√5, which represents the perimeter of the triangle.
