A
3
A. 3.5
B. 4
C. 10
D. 10.5
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

Find the 91st term of the arithmetic sequence 28, 8, –12, ...
Anybody know the answer?
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
The student government wants to determine the theme for the eighth-grade dance. Which group would it be best to take a sample from?
A.) student government
B.) eighth-grade students
C.) eighth-grade students in student government
D.) middle school students
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.

Find the inequality represented by the graph.
Answer:
y > 4x - 2
Step-by-step explanation:
y-intercept is at -2
slope is rise by 4, run by 1
if you don't know where to shade, select a point and plug it in to see if T or F
example (0, 0)
is 0 > 4(0) - 2
is 0 > -2 True, so shade to the left because this is where (0,0) is
Answer:
Step-by-step explanation:
Analyze what each part of the inequality means mathematically.x is the solution of the problem, the quantity you are looking for.6x means that, for a reason given in the problem, the quantity you are looking for is multiplied by 6.− 18 means that, for a reason given in the problem, 18 is subtracted from 6x.≤ 18 means that after multiplying the solution x by 6 and subtracting 18 from it, the result is at most 18.Think of some different situations in which a quantity x might be multiplied by 6.You plant 6 seeds from x different seed packets, and you want to know from how many different seed packets you plants seeds.Build on the situation and adjust it to create a verbal description that takes all of the information of the inequality into account.Elrich planted 6 seeds from each of x different seed packets in his garden. To plant these seeds, he had to remove 18 plants that were already in the garden. Including the plants he removed and the seeds he planted, he expected to have at most 18 plants in the garden. From how many different seed packets did Elrich recently plant seeds?

Answer:58, 1,102,
Step-by-step explanation:
An object is launched directly in the air at a speed of 72 feet per second from a platform located 12 feet above the ground. The position of the object can be modeled using the function f(t)=−16t2+72t+12, where t is the time in seconds and f(t) is the height, in feet, of the object. What is the maximum height, in feet, that the object will reach?
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:
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:
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:
Option CStep-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.

A scooter maintains a pace of 1.45 minutes per mile, with fuel economy of 85 miles per gallon. How many seconds can it travel on 145 mL of fuel under these conditions?
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
Find the length of each arc .
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]
y=8x^2 linear or non linear
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.
Let f(x) = 2x + 2 and g(x) = 5x2 + 2x.
After simplifying,
(f + g) (x)
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

A line has this equation: x + y = 6
Write an equation for the perpendicular line that goes through (5, 1).
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]
