1 1/3

Step-by-step explanation:

Answer:

7/6

Step-by-step explanation:

1/3+4/8+6/18=7/6

Work Shown:

(f + g)(x) = f(x) + g(x)

(f + g)(x) = ( f(x) ) + ( g(x) )

(f + g)(x) = (2x+2) + (5x^2+2x)

(f + g)(x) = 2x+2 + 5x^2 + 2x

(f + g)(x) = 5x^2 + (2x+2x) + 2

(f + g)(x) = 5x^2 + 4x + 2

Answer:

it is c

Step-by-step explanation:

with every letter there is, each letter has and is its own variable, so each factor would have its own expression not equation. with 2/5 you would have 2/5a, 2/5b, and 2/5c

i hope this helps

Answer:

Step-by-step explanation:

We can tell that the variables that are multiplying the constants are a, b, and c. It is a must that 2/5 is also a factor because it is the number that is started the multiplication. Hence, the factors are 2/5, a, b, and c. This answer matches with Option C.

Hence, Option C is correct.

Answer:

$400 dollars in five dollar tickets then $399 dollars in seven dollar tickets.

so you do $400+$399=799

Step-by-step explanation:

You do $400÷5=80 then you do $395R4÷7=55 Then you do 55+80=$135.

so 55 adult tickets and then 80 student tickets.

Step-by-step explanation:

Answer:

y = [tex]\frac{3}{2 + 3Ce^{-3t} }[/tex]

Step-by-step explanation:

As given , y' = 3y - 2y²

⇒y' - 3y = -2y²

Divide by y² in the above equation

⇒[tex]\frac{y'}{y^{2} } - \frac{3y}{y^{2} } = -\frac{2y^{2} }{y^{2} }[/tex]

⇒[tex]\frac{y'}{y^{2} } - \frac{3}{y } = -2[/tex]       ........(1)

Now , let [tex]\frac{1}{y}[/tex] = u

⇒-[tex]\frac{1}{y^{2} } \frac{dy}{dt} = \frac{du}{dt}[/tex]

⇒-[tex]\frac{1}{y^{2} }y' = \frac{du}{dt}[/tex]

∴ equation (1) becomes

-[tex]\frac{du}{dt}[/tex] - 3u = -2

⇒[tex]\frac{du}{dt}[/tex] + 3u = 2

It is a linear differential equation

Now,

Integrating factor = I.F = [tex]e^{\int\limits {3} \, dt }[/tex] = [tex]e^{3t}[/tex]

∴ The solution becomes

u.(I.F) = [tex]\int\limits {2.(I.F)} \, dt[/tex] + C

⇒u.([tex]e^{3t}[/tex]) = [tex]\int\limits {2.(e^{3t} )} \, dt[/tex] + C

⇒u.([tex]e^{3t}[/tex]) = [tex]\frac{2e^{3t} }{3}[/tex] + C

⇒u = [tex]\frac{2}{3} + Ce^{-3t}[/tex]

As [tex]\frac{1}{y}[/tex] = u

⇒[tex]\frac{1}{y}[/tex]  = [tex]\frac{2}{3} + Ce^{-3t}[/tex]

⇒ y = [tex]\frac{1}{\frac{2}{3} + Ce^{-3t} } = \frac{3}{2 + 3Ce^{-3t} }[/tex]

⇒ y = [tex]\frac{3}{2 + 3Ce^{-3t} }[/tex]

Answer:

well the range is -9 to 11 also written as -9 < x < 11

Step-by-step explanation:

Answer:

-1772

Step-by-step explanation:

The nth term of an arithmetic sequence is expressed as;

Tn = a+(n-1)d

a is the first term

n is the number of terms

d is the common difference

From the sequence

a = 28

d = 8-28 = -12-8 = -20

n =91(since we are looking for the 91st term)

Substrate

T91 = 28+(91-1)(-20)

T91 = 28+90(-20)

T91 = 28-1800

T91 = -1772

Hence the 91st term is -1772

Answer:

A. [tex] 12\pi [/tex] mi

Step-by-step explanation:

Length of arc = r∅

Where,

Radius (r) = 16 mi

Angle in radians (∅) = [tex] \frac{3\pi}{4} [/tex]

Plug in the values

Length of arc = [tex] 16*\frac{3\pi}{4} [/tex]

Length of arc = [tex] \frac{16*3\pi}{4} [/tex]

Length of arc = [tex] \frac{4*3\pi}{1} [/tex]

Length of arc = [tex] 12\pi [/tex]

Answer:

93 feet

Step-by-step explanation:

The highest point the object will be the vertex of the given function. Because the derivative of the function at the vertex is zero, we can set up the equation f'(t)=0. After substituting, we get t=2.25 as the x coordinate. when we plug this vaule we get 93.

Answer:58, 1,102,

Step-by-step explanation:

Answer:

A. 3.5

Step-by-step explanation:

Given that AB is parallel to A'B', therefore,

CB/CB' = CA/CA'

CB' = 7

CB = CB' + BB' = 7 + BB'

CA' = 6

CA = CA' + AA' = 6 + 3 = 9

Plug in the values

(7 + BB')/7 = 9/6

(7 + BB')/7 = 3/2

Cross multiply

2(7 + BB') = 7(3)

14 + 2BB' = 21

Subtract 14 from both sides

2BB' = 21 - 14

2BB' = 7

Divide both sides by 2

BB' = 7/2

BB' = 3.5

Answer:

-27

Step-by-step explanation:

Just solve the equation by subtracting 34-23= 11, then multiply 11 by 3, which is what you get from subtracting 5-2= 3. Finally, subtract 33-60= -27.

Answer:

283 seconds

Step-by-step explanation:

The computation of the number of seconds would it travel is as follows

Pace is

[tex]\frac{1.45\ minute}{mile}= \frac{87\ seconds}{mile} \\\\Fuel\ economy = \frac{85\ mile}{gallon}[/tex]

The volume of fuel = 145 ml = 0.0383 gallon

Now from 145 ml of the scooter fuel would be

= [tex]\frac{85\ mile}{gallon} \times 0.0383\ gallon[/tex]

= 3.255 mile

Now time for travel is

= [tex]\frac{87\ sec}{mile} \times 3.255\ mile\\[/tex]

= 283 seconds

The correct answer is B.) Eight-grade students

Explanation:

The purpose of a sample is to choose a reduced number of people from a specific population to study and analyze their opinions, behavior, ideas, etc. as part of a research process. Moreover, the sample or individual selected is directly related to the purposes of the research. For example, in research about the opinions of citizens about new policies, the citizens of the specific country or city should be selected.

In this context, eighth-grade students should be selected as part of the sample because this group is directly affected by the theme of the eighth-grade dance. Also, it is the interest of this group the one that determines the final theme rather than all the students or the student government.

Answer:

Non Linear

Step-by-step explanation:

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 2.

Answer:

Step-by-step explanation:

Answer:

the equation of the line will be: [tex]y=x-4[/tex]

Step-by-step explanation:

Equation of line: x + y = 6

We need to write an equation for the perpendicular line that goes through

(5, 1).

The equation will be in slope-intercept form [tex]y=mx+b[/tex] where m is slope and b is y-intercept

Finding Slope:

Equation of line given is: x+y=6

Writing it in slope-intercept form: [tex]y=-x+6[/tex]

The slope of this line is m = -1 (By comparing it with [tex]y=mx+b[/tex] we get m = -1)

Since the required line is perpendicular, their slopes will be opposite inverse of each other i.e. [tex]m_1=-\frac{1}{m_1}[/tex]

So, slope of required line will be: m=1

Now, using the point (5,1) and slope m=1 we can find y-intercept

[tex]y=mx+b\\1=1(5)+b\\1=5+b\\b=1-5\\b=-4[/tex]

So, we get y-intercept b = -4

Now, the equation of required line, having slope m=1 and y-intercept b = -4

[tex]y=mx+b\\y=1x-4[/tex]

So, the equation of the line will be: [tex]y=x-4[/tex]
