Given the fucntion:

f(x) = tanx

Let's graph the function and input the correct values in the box.

• To find the y-intercept of the function, input 0 for x and solve:

[tex]\begin{gathered} f(0)=\tan 0 \\ \\ f(0)=0 \end{gathered}[/tex]

Therefore, the y-intercept is:

(0, 0)

• The period of the function:

The fundamental period of a tangent function is π.

Now, let's find points on the graph:

Therefore, the points are:

[tex]\mleft(-\frac{\pi}{3},-\sqrt{3}\mright),\mleft(-\frac{\pi}{4},-1\mright),\mleft(0,0\mright),\mleft(\frac{\pi}{4},1\mright),\mleft(\frac{\pi}{3},\sqrt{3}\mright)[/tex]

ANSWER:

A friend plans to purchase a 72-inch tv at a particular store for a cost of $1500. The store is offering 25% off any one item. He also has an internet coupon for an additional 10% off any discounted price. How much will your friend save (a) in dollar amount and (b) in percent?

Answers

the The Solution.

The marked price of the 72-inch TV = $1500

25% discount makes the actual discount to be:

[tex]\begin{gathered} \text{Actual Discount = 25 \% of 1500} \\ \text{ = }\frac{25}{100}\times1500=\text{ \$375} \end{gathered}[/tex]

Answers

The ways to select the winning numbers is 286

How to determine the ways the winning numbers could be drawn?

From the question, we have

Total numbers, n = 13Numbers to select, r = 3

The winning numbers could be drawn is calculated using the following combination formula

Total = ⁿCᵣ

Where

n = 13 and r = 3

Substitute the known values in the above equation

Total = ¹³C₃

Apply the combination formula

ⁿCᵣ = n!/(n - r)!r!

[tex]8.25 \div 6[/tex]8.25 divid by 6

Answers

We want to calculate the following number

[tex]\frac{8.25}{6}[/tex]

To make the calcul.ation easier, we will transform the number 8.25 into a fraction. Recall that

[tex]8.25=\frac{825}{100}[/tex]

So, so far, we have

[tex]\frac{8.25}{6}=\frac{\frac{825}{100}}{6}[/tex]

Also, recall that

[tex]6=\frac{6}{1}[/tex]

So, we have

[tex]\frac{\frac{825}{100}}{6}=\frac{\frac{825}{100}}{\frac{6}{1}}[/tex]

Now, recall that when we divide fractions, we have

[tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot d}{b\cdot c}[/tex]

In this case, we have a=825,b=100,c=6,d=1.

The cost C (in dollars) of producing x units of a product is given by the following. C= 2.6. Square root of x + 600

Answers

The marginal cost in dollars of producing x units is given by the next equation:

[tex]C=2.6\sqrt[]{x}+600[/tex]

a)

To find the marginal cost (in dollars per unit) when x= 9.

Then, we need to replace x=9 on the derivation of the cost equation:

So:

[tex]\frac{d}{dx}C=\frac{1.3}{\sqrt[]{x}}[/tex]

Where:

[tex]\frac{d}{dx}2.6\sqrt[]{x}=2.6\frac{d}{dx}\sqrt[]{x}=2.6\frac{d}{dx}^{}x^{\frac{1}{2}}=2.6\cdot\frac{1}{2}x^{\frac{1}{2}-1}=1.3\cdot x^{-\frac{1}{2}}=\frac{1.3}{\sqrt[]{3}}[/tex]

and, the derivate of a constant is equal to zero.

[tex]\frac{d}{dx}600=0[/tex]

Replacing x= 9

[tex]\frac{d}{dx}C=\frac{1.3}{\sqrt[]{9}}[/tex]

Hence, the marginal cost is equal to:

[tex]\frac{d}{dx}C=0.43[/tex]

b) Now, when the production increases 9 to 10. It's the same as the cost of producing one more machine beyond 9.

Then, it would be x=10 on the cost equation:

[tex]C=2.6\sqrt[]{x}+600[/tex][tex]C=2.6\sqrt[]{10}+600[/tex][tex]C=608.22[/tex]

and x= 9

[tex]C=2.6\sqrt[]{9}+600[/tex][tex]C=2.6(3)+600[/tex][tex]C=607.8[/tex]

Then, we calculate C(10) - C(9) =

[tex]608.22-607.8[/tex][tex]=0.43[/tex]

C)

Both results are equal.

Hence, the marginal cost when x=9 is equal to the additional cost when the production increases from 9 to 10.

Two functions are shown. f(x) = 29(0.5)* g(x) = 18x + 14 What is the value of f(2) + g(4)?

Answer:

93.25

Explanation:

Given the below functions;

[tex]\begin{gathered} f(x)=29(0.5)^x \\ g(x)=18x+14 \end{gathered}[/tex]

To be able to find the value of f(2) + g(4), we have to 1st determine the value of f(2) and f(4) as shown below;

[tex]\begin{gathered} f(2)=29(0.5)^2=29\ast0.25=7.25 \\ g(4)=18(4)+14=72+14=86 \end{gathered}[/tex]

Write an equation for the graph below in point-slope form and then solve rewrite in slope-intercept form.

Answers

We are given the graph of a line and we are asked to determine its equation in point-slope form.

The general form in slope point form of a line is:

[tex]y-y_0=m(x-x_0)[/tex]

Where:

[tex]\begin{gathered} m=\text{ slope} \\ (x_0,y_0)\text{ is apoint in the line} \end{gathered}[/tex]

to determine the slope we will use the following formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where:

[tex](x_1,y_1);(x_2,y_2)=\text{ points on the line}[/tex]

We will choose two points on the line from the graph:

[tex]\begin{gathered} (x_1,y_1)=(0,1) \\ (x_2,y_2)=(2,2) \end{gathered}[/tex]

Now, we plug in the values in the formula for the slope:

[tex]m=\frac{2-1}{2-0}=\frac{1}{2}[/tex]

Now, we substitute the value of the slope in the equation of the line:

[tex]y-y_0=\frac{1}{2}(x-x_0)[/tex]

Now, we plug in the first point we choose for the line:

[tex]\begin{gathered} y-1=\frac{1}{2}(x-0) \\ \\ y-1=\frac{1}{2}x \end{gathered}[/tex]

And thus we have determined the equation of the line in point-slope form.

The slope-intercept form is the following:

[tex]y=mx+b[/tex]

To convert this equation to slope-intercept form, we will take the previous equations and we will add 1 to both sides:

[tex]y=\frac{1}{2}x+1[/tex]

And thus we have determined the slope-intercept form of the equations of the line.

There are 6 dogs and 2 mice. Write a ratio for the number of ears to th number of paws. * 6:2 3 people are in a room. Write a ratio to represent the number of finger

Answers

each dog has 4 paws, then 6 dogs have 6*4 = 24 paws

each mouse has 4 paws, then 2 mice have 2*4 = 8 paws

Total number of paws: 24 + 8 = 32 paws

each dog has 2 ears, then 6 dogs have 6*2 = 12 ears

each mouse has 2 ears, then 2 mice have 2*2 = 4 ears

total number of ears: 12 + 4 = 16 ears

The ratio for the number of ears to the number of paws: 16/32 = 1/2 or 1:2

What is the product of 11/12 and its reciprocal?

Answers

Answer:

The product of 11/12 is 0.916.This as as a fraction would be 0.916/1.00. This means it's reciprocal is 1.

Step-by-step explanation:

The reciprocal is basically the bottom part, denominator, of the fraction, being siwtched to on top of the fraction (numerator, and vice versa. The fraction would be 0.916/ 1.00 because the closest whole number to 0.916 is 1, meaning the fraction would be 0.916 out of 1. DO NOT MISTAKE THIS FOR 100. When you do the final step, finding the recirprocal of 0.916/1.00, we siwtch the numerator and denominators position, making out answer:

The product of 11/12 is 0.916 which is 0.916/1.00 in fraction form. The reciprocal of this is 1.00/0.916. Hope this helped!

Work Shown:

A = he eats pizza

B = he drinks cola

P(A) = 0.40

P(B) = 0.60

P(A and B) = 0.30

Then apply the conditional probability formula.

P(A given B) = P(A and B)/P(B)

P(A given B) = 0.30/0.60

P(A given B) = 0.5 exactly

a) The probability that a randomly selected individual is 45-54 years of age, given the individual is neither more nor less likely to buy is 0.206

b) The probability that a randomly selected individual is neither more nor less likely to buy, given the individual is 45-54 years of age is 0.309

c) 18-34 year olds are less likely to buy a product emphasized as "Made in our country" than individuals in general.

Hence, the answer is no.

A random sample is one that is drawn at random from the population, meaning that every member of the population has an equal chance of being picked for the sample. The probability sampling approach is the practice of choosing people at random.

a. Total number of individuals that are neither more nor less likely to purchase = 786

Total number of individuals aged 45-54 that are neither more nor less likely to purchase = 162

The probability that a randomly selected individual is 45-54 years of age, given the individual is neither more nor less likely to buy =

= Total number of individuals aged 45-54 neither more or less likely to purchase./ Total number of individuals more or less likely to purchase.

= 162/786

= 0.206

b. Total number of individuals 45-54 years of age =  524

Total number of individuals aged 45-54 that are neither more nor less likely to purchase = 162

The probability that a randomly selected individual is neither more nor less likely to buy, given the individual is 45-54 years of age

= Total number of individuals aged 45-54 neither more or less likely to purchase./ Total number of individuals 45-54 years of age.

= 162/524

= 0.309

c. The number of 18-34 year old individuals more likely to buy = 204

The total number of 18-34 year old individuals = 523

The proportion of 18-34 year old individuals more likely to buy = 204/523

= 0.390

= 39%

The total number of individuals more likely to buy = 1266

The total number of all individuals in the survey = 2123

The proportion of individuals, in general, more likely to buy = 1266/2123

= 0.596

= 59.6%

Therefore, 18-34 year olds are less likely to buy a product emphasized as "Made in our country" than individuals in general.

Hence, the answer is no.

How to draw the graphs of the following non-linear functions?y=x^2 + 1y=3^x + 1

Answers

The first step is to substitute values of x into each equation.

For y = x^2 + 1,

if x = - 2, y = (- 2)^2 + 1 = 4 + 1 = 5

if x = - 1, y = (- 1)^2 + 1 = 1 + 1 = 2

if x = 0, y = (0)^2 + 1 = 0 + 1 = 1

if x = 1, y = (1)^2 + 1 = 1 + 1 = 2

if x = 2, y = (2)^2 + 1 = 4 + 1 = 5

We would plot the corresponding values of x and y on the graph as shown below

For y = 3^(x + 1),

if x = - 2, y = 3^(-2 + 1) = 3^-1 = 0.33

if x = - 1, y = 3^(-1 + 1) = 3^0 = 1

if x = 0, y = 3^(0 + 1) = 3^1 = 3

if x = 1, y = 3^(1 + 1) = 3^2 = 9

if x = 2, y = 3^(2 + 1) = 3^3 = 27

We would plot the corresponding values of x and y on the graph as shown below

Difference of two squares

A difference of two squares is factored as follows:

x² - y² = (x + 2)(x - 2)

Hence one possible example is:

x² - 4 = (x + 2)(x - 2).

Compared to the perfect square trinomial, we have that:

The similarity is that the first term in any of the two polynomials will  always be positive.The difference is in the last term, for the perfect square it will always be positive (+ b²) and for the difference of two squares it will always be negative (- b²).

We are supposed to solve the equation

[tex]6(2x-1)-12=3(7x+4)[/tex]

Here, we need to apply the distributive laws on both sides.

Comment: The distributive laws say that

[tex]a(b+c)=ab+ac\text{ and }(b+c)a=ba+ca[/tex]

Using this comment we get

[tex]6(2x-1)=6(2x)+6(-1)=12x-6[/tex][tex]3(7x+4)=3(7x)+3(4)=21x+12[/tex]

Then, our equation becomes

[tex](12x-6)-12=21x+12[/tex][tex]12x-18=21x+12[/tex]

Now, let's apply the rule: terms with x on the right-hand side, and the rest on the left-hand side, to obtain

[tex]-18-12=21x-12x[/tex][tex]-30=9x[/tex][tex]x=\frac{-30}{9}=-\frac{10}{3}[/tex]

12. A teacher weighed 148 lbs. in 1999 and weighs 190 lbs. In 2020. What was the rate ofchange in weight?

Answers

Given,

The weight of the teacher in 1999 is 148 lbs.

The weight of the teacher in 2020 is 190 lbs.

The rate of change in weight is,

[tex]\begin{gathered} \text{Rate of change=}\frac{190-148}{2020-1999} \\ =\frac{42}{21} \\ =2 \end{gathered}[/tex]

The teacher gained 2 pounds per year.

Hence, option A is correct.

A uniform rod of mass mr = 158 g and length L = 100.0 cm is attached to the wall with a pin as shown. Cords are attached to the rod at the r1 = 10.0 cm and r2 = 90.0 cm mark, passed over pulleys, and masses of m1 = 281 g and m2 = 177 g are attached. Your TA asks you to determine the following: (a) The position r3 on the rod where you would suspend a mass m3 = 200 g in order to balance the rod and keep it horizontal if released from a horizontal position. In addition, for this case, what force (magnitude and direction) does the pin exert on the rod? Use standard angle notation to determine the direction of the force the pin exerts on the rod. Express the direction of the force the pin exerts on the rod as the angle F, measured with respect to the positive x-axis (counterclockwise is positive and clockwise is negative). r3 = Fp =F = (b) Let's now remove the mass m3 and determine the new mass m4 you would need to suspend from the rod at the position r4 = 20.0 cm in order to balance the rod and keep it horizontal if released from a horizontal position.
