Step-by-step explanation:
Answer:
Step-by-step explanation:
(x+3)/8 = (x+6)/10
x+3 = 8(x+6)/10
x+3 = 4(x+6)/5
x+3 = (4x+24)/5
x +3 = 4x/5 + 24/5
x - 4x/5 = (24/5)-3
x/5 = 9/5
x = 9
Suppose a small cannonball weighing 16 lb is shot vertically upward with an initial velocity
v_0 = 300v 0 =300 ft/s.(a) Suppose air resistance is ignored. If the positive direction is upward, then a model for the state of the cannonball is given by d^2s/dt^2 = -gd 2 s/dt 2 =−g.Since ds/dt = v(t)ds/dt=v(t) the last differential equation is the same as dv/dt = -gdv/dt=−g, where we take g = 32g=32 ft/s^2 2 . Find the velocity v(t)v(t) of the cannonball at time tt.(b) Use the result obtained in part (a) to determine the height s(t)s(t) of the cannonball measured from ground level. Find the maximum height attained by the cannonball.
Answer:
a) v(t)=-32t+300
b) s(t)=-16t^{2}+300t
[tex]s_{max} =\frac{5625}{4}ft=1406.25 ft[/tex]
Step-by-step explanation:
A good way to start solving this problem out is to draw a diagram of the situation (see attached picture).
a)
For part a, we need to find an equation for the velocity of the cannon ball. We have an equation of its acceleration:
[tex]a=\frac{dv}{dt}=\frac{d^{2}s}{dt^{2}}=-g[/tex]
we know that:
[tex]g=32 ft/s^{2}[/tex]
so we got the following differential equation:
[tex]\frac{dv}{dt} =-32[/tex]
we can find the function for velocity by integrating, so we get:
[tex]v =\int\limits {-32} \, dt[/tex]
which yields:
v(t)=-32t+C
we need to find the value of C. The problem tells us that v(0)=300 ft/s so we can use this to find c:
300=-32(0)+C
so
C=300
therefore the equation for velocity is:
v(t)=-32t+300
b)
For part b) we need to find an equation for the height of the cannonball. We know that:
[tex]v=\frac{ds}{dt}[/tex]
so:
[tex]\frac{ds}{dt}=-32t+300[/tex]
so we can integrate this equation to find the function for height of the ball, so we get:
[tex]s=\int\limits {-32t+300} \, dt[/tex]
which yields:
[tex]s(t)=-\frac{32t^{2}}{2}+300t+C[/tex]
which can be simplified to:
[tex]s(t) =-16t^{2}+300t+C[/tex]
We know the height is measured from the ground level, this means that s(0)=0 so we can find C with this information:
[tex]0=-16(0)^{2}+300(0)+C[/tex]
so C=0, therefore our equation is:
[tex]s(t)=-16t^{2}+300t[/tex]
in order to find the maximum height attained by the cannonball, we can set the velocity function equal to zero and solve for t, so we get:
0=-32t+300
-32t=-300
[tex]t=\frac{300}{32}[/tex]
[tex]t=\frac{75}{8} s[/tex]
and substitute it into our position function so we get:
[tex]s(\frac{75}{8})=-16(\frac{75}{8})^{2}+300(\frac{75}{8})[/tex]
which yields:
[tex]s_{max} =\frac{5625}{4}ft=1406.25 ft[/tex]
In a large population, 61 % of the people have been vaccinated. If 3 people are randomly selected, what is the probability that AT LEAST ONE of them has been vaccinated
Answer:
0.94
Step-by-step explanation:
Computation for what is the probability that AT LEAST ONE of them has been vaccinated
Based on the information given this is a binomial Distribution therefore Let;
Number of people represent n= 3 people
Population represent p = .61
Using this formula
Probability(AT LEAST ONE vaccinated) = 1 - [ 1*(1-Population vaccinated^People randomly selected)]
Let plug in the formula
Probability(AT LEAST ONE vaccinated) = 1 -[1*(1-.61^3)]
Probability(AT LEAST ONE vaccinated) = 1 - [1×(1-.61^3)]
Probability(AT LEAST ONE vaccinated) = 1 - (1×.39^3)
Probability(AT LEAST ONE vaccinated) = 1 - 0.059319
Probability(AT LEAST ONE vaccinated) = 0.940681
Probability(AT LEAST ONE vaccinated) = 0.94
Therefore the probability that AT LEAST ONE of them has been vaccinated is 0.94
given that y varies inversely with x, and y = 100 when x + 3, find x if y = 60
Step-by-step explanation:
xy = k, where k is a real constant.
y = 100 when x = 3, therefore (3)(100) = k.
=> k = 300.
Hence when y = 60, x(60) = (300), x = 5.

An aquarium holds 12 liters of water.
How many aquariums can we fill with 48 liters of water?
Include fractions of aquariums, if applicable.
Answer:
4 aquariums
Step-by-step explanation:
because each aquarium can hold 12 liters and if there is 48 liters total you divide 48 by 12 and get a total of 4 aquariums
determine the value of x for which r parallels s. then find measure of angles one and two
measure of angle one= 30-4x
measure of angle two= 50-44x
the value for which r parallels s is .....
measure of angle one.....
measure of angle two ......
Answer:
[tex] m\angle 1 = 28\degree
m\angle 2 = 28\degree [/tex]
Step-by-step explanation:
[tex]\because line\: r || line\: s\\
m\angle 1 = m\angle 2\\(corresponding \: \angle s) \\
\therefore 30 - 4x = 50 - 44x\\
\therefore 44x - 4x = 50 - 30\\
\therefore 40x = 20\\
\therefore x = \frac{40}{20}\\
\therefore x = 0.5\\
m\angle 1 = 30 - 4x = 30 - 4(0.5) = 30 - 2 \\
m\angle 1 = 28\degree \\
\implies m\angle 2 = 28\degree [/tex]

Answer:
42.857 kg
Step-by-step explanation:
Given that :
Weight of body = 420N
Recall : Weight (W) = mass(m) * acceleration due to gravity(g)
Thus ;
Mass, m = Weight, W / acceleration due to gravity
Acceleration due to gravity is a constant, g =, 9.8 m/s²
Mass = 420N / 9.8m/s²
Mass = 42.857142kg

Compare continuous functions f, g, and h, and match the statements with the function they best describe.
Drag each description to the correct location on the table.
Answer: see attached
Step-by-step explanation:
From the given properties of the functions,
Function 'f' is decreasing in the longest interval [-0.8, 0.6]Lowest y-intercept → y = -1 (function g)Highest y-intercept → y = 3 (function h)Function 'h' in increasing in the longest interval → (-∞, ∞)Functions given in the picture are 'f', 'g' and 'h'.
From the graph given for function 'f',
y - intercept = 1
Increasing in the interval → (-∞, -0.8] and (0.6, ∞)
Decreasing in the interval → [-0.8, 0.6]
From the table given for the function 'g',
Decreasing in the interval → [-2, 2]
y-intercept = -1
For function 'h',
h(x) = 4x³ + 3
Table of the input-output values for function will be,
x h(x)
-2 -29
-1 -1
0 3
1 7
2 35
Therefore, function 'h' will increase in the interval → (-∞, ∞)
y-intercept → y = 3
Therefore, from these properties of the functions we conclude,
Function 'f' is decreasing in the longest interval [-0.8, 0.6]Lowest y-intercept → y = -1 (function g)Highest y-intercept → y = 3 (function h)Function 'h' in increasing in the longest interval → (-∞, ∞)Learn more,

snowballs, how many did the boys

Answer:
1500
Step-by-step explanation:
1200/4=300
1200+300=1500
Answer:
This means the boys throw 300 snowballs while Buddy throws 1200 snowballs
Step-by-step explanation:
Equations
Let's call
x = number of snowballs the other boys throw.
4x = number of snowballs Buddy throws.
We know Buddy throws 1200 snowballs, thus
4x = 1200
Divide by 4:
x = 1200/4
x = 300
This means the boys throw 300 snowballs while Buddy throws 1200 snowballs
