Answer:

26sqrt(3)

Step-by-step explanation:

You end up with two 30-60-90 triangles.

26/2 = 13

2 * 13 * sqrt(3) = 26sqrt(3)

A fourth-degree polynomial in standard form is :

       In this example it would give:

      −6[tex]x^{4}[/tex]+3[tex]x^{2}[/tex]+4x +2

The closure property as it relates to polynomials are :

       (2x2 + 3x + 4) + (x2 - 5x - 3)

        3x2 - 2x + 1.

Therefore, the addition and subtraction of polynomials is closed.

The correct option is;

Option 3. 2.5

Step-by-step explanation:

From the graph of the function y = h(x), where h of x h(x) > 0 and x > 0 we have;

The first interval where y =h(x) > 0 occurs between x= 0 and x = 0.8

The second interval where y =h(x) > 0 occurs between 2.2 and 4 which is a range of 4 - 2.3 = 1.7

The total interval where y =h(x) > 0 occurs is therefore = 0.8 + 1.7 = 2.5

Thus the function y = h(x), is positive over an interval on the x-axis = 2.5.

Answer:

The result is 150 + 1.5d

Step-by-step explanation:

We want to translate the wordings into algebraic expression.

Firstly, we increase 120 by d%

d% = d/100

So increasing 120 by d % means;

120 + (d/100 * 120)

= 120 + 1.2d

Then increase this by 25%

= (120 + 1.2d) + 25/100(120 + 1.2d)

= 120 + 1.2d + (120+1.2d)/4

= 120 + 1.2d + 30 + 0.3d

= 120 + 30 + 1.2d + 0.3d

= 150 + 1.5d

Step-by-step explanation:

Answer:

y = 5/12 x + 2

Step-by-step explanation:

We need to find the equation of a line that passes through two given points.

y = mx + b

First, we find the slope.

m = slope = (y2 - y1)/(x2 - x1)

m = (7 - 2)/(12 - 0) = 5/12

Now we have

y = 5/12 x + b

To find the value of b, we use a point for x and y and solve for b.

y = (5/12)x + b

2 = (5/12)(0) + b

b = 2

The equation is

y = 5/12 x + 2

Answer:

As color is simply the kind of light reflected by surfaces(if the sun was green, many plants would die), color can be explained fairly simply to a blind person.  Each color represents a separate wavelength, and objects that reflect these wavelengths show up in various colors.  Thus simply state the following: The color blue is displayed by all objects that reflect wavelengths from 380 and 500 nanometers.

Answer:

The correct option is (b) 0.333.

Step-by-step explanation:

The data provided is as follows:

                        Hepatitis C           No hepatitis C           Total

No Tattoos              5                             50                        55

 1 Tattoo                 10                           210                      220

> 1 Tattoo                15                           150                       165

   Total                   30                           410                       440

The probability of an event E is the ratio of the favorable number of outcomes to the total number of outcomes.

[tex]P(E)=\frac{n(E)}{N}[/tex]

The condition probability of an event A provided that another event X has already occurred is:

[tex]P(A|X)=\frac{P(A\cap X)}{P(X)}[/tex]

The number of people who has hepatitis C is:

n (Hepatitis C) = 30

The number of people who has hepatitis C and one tattoo is:

n (Hepatitis C and 1 Tattoo) = 10

Compute the probability that he or she has hepatitis C, given that he or she has one tattoo as follows:

[tex]P(\text{Hepatitis C} |\text{1 Tattoo})=\frac{n(\text{Hepatitis C and 1 Tattoo})}{n(\text{1 Tattoo})}[/tex]

                                       [tex]=\frac{10}{30}\\\\=\frac{1}{3}\\\\=0.333[/tex]

Thus, the correct option is (b).

The probability that he or she has hepatitis C, given that he or she has one tattoo will be 0.333. Then the correct option is B.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

The table is given below.

                       Hepatitis C           No hepatitis C           Total

No Tattoos              5                             50                        55

1 Tattoo                 10                           210                      220

> 1 Tattoo                15                           150                       165

  Total                   30                           410                       440

The number of people who has hepatitis C is 30. And the number of people who has hepatitis C and one tattoo is 10.

The probability that he or she has hepatitis C, given that he or she has one tattoo will be

P = 10/30

P = 1/3

P = 0.333

The probability that he or she has hepatitis C, given that he or she has one tattoo will be 0.333. Then the correct option is B.

Hey there! :)

Answer:

86° F.

Step-by-step explanation:

Use the formula C = 5/9(F - 32) to convert 30C to Fahrenheit. Plug 30 into C:

30 = 5/9(F - 32)

Multiply both sides by 9/5 (dividing by 5/9):

30 · 9/5 = 5/9(F - 32) · 9/5

54 = F - 32

Add 32 to both sides:

54 + 32 = F - 32 + 32

F = 86°.

Therefore, 30C = 86° F.

Answer: D. 143

Step-by-step explanation:

31 times 4.26 = 132.06 + 10.908 = 142.968 which simplifies to 143 because you round up.

The best line of fit for the maximum depth of the shoreline would be: D. 143 feet

We have the line of fit as

y = 4.26x + 10.908.

The question has specified x as 31 miles which is the miles of shore line.

We have to solve for the value in the line of best fit

y = 4.26*31 + 10.908

y = 132.06 + 10.908

y = 142.968

This is approximately D. 143 feet

Answer:

Acá tenemos un sistema de ecuaciones.

El perímetro de un rectángulo es:

2*A + 2*L = 170m

donde A es el ancho y L es el largo.

Y el área del rectángulo es:

A*L = 170m^2.

Entonces, el primer paso es aislar una de las variables en una de las ecuaciones, yo voy a aislar A en la segunda:

A = 170m^2/L.

Ahora reemplazo eso en la primera ecuación y la resuelvo para L.

2*( 170m^2/L.) + 2*L = 170m.

340m^2 + 2*L^2 = 170m*L

ahora tenemos una ecuación cuadrática:

2*L^2 - 170m*L + 340m^2 = 0.

Las soluciones se pueden obtener usando la formula de Bhaskara:

[tex]L = \frac{+170 +- \sqrt{170^2 -4*340*2} }{2*2} = \frac{170 +-161.8}{4}[/tex]

Entonces las soluciones son:

L = (170 + 161.8)/4 = 82.95m

L = (170 - 161.8)/4 = 4.1m

Entonces, si tomamos L = 82.95m, tenemos A = 4.1 m

y el área es:

A*L = 4.1m*82.95m = 170m^2

Missing part of the question is;

Find a formula for the number of seats sold if the ticket price is P dollars.

Answer:

(680 - P)/3

Step-by-step explanation:

A) Let x be equal to the number of seats and hence we can conclude that (160 - x) is equal to the number of seats after the increase in price.

Similarly, the increase in ticket price would be equal to (P - 200)

Due to the fact that for every $3 increase, the number of seats decrease by 1, the equation that links the change in the number of seats to the change in ticket price is;

P - 200 = 3(160 - x)

P = 3(160 - x) + 200

Making x the subject;

P = 480 - 3x + 200

P = 680 - 3x

3x = 680 - P

x = (680 - P)/3

No.
