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

Answer:

Your answer is attached in the answer

Answer: see attached

Step-by-step explanation:

 From the given properties of the functions,

 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,

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.

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

Answer:

300°

Step-by-step explanation:

Difference means to subtract:

127 - (-173) = 300

Therefore, the temperatures have a difference of 300°.

Answer: 300

Step-by-step explanation:

The max temp is 127C

The min temp is -173C

The difference between the maximum and minimum temperatures = max temp - min temp= 127-(-173) = 127+173=300

Algebra I

Step-by-step explanation:

Step 1: Define

ax - bx + y = z

Step 2: Solve for x

Answer:

The solution for x will be:

[tex]x=\frac{z-y}{a-b}[/tex]

Step-by-step explanation:

Given the expression

[tex]ax-bx+y=z[/tex]

subtract y from both sides

[tex]ax-bx+y-y=z-y[/tex]

simplify

[tex]ax-bx=z-y[/tex]

Factor ax-bx = x(a-b)

[tex]x\left(a-b\right)=z-y[/tex]

Divide both sides by a-b;  a≠b

[tex]\frac{x\left(a-b\right)}{a-b}=\frac{z}{a-b}-\frac{y}{a-b};\quad \:a\ne \:b[/tex]

simplify

[tex]x=\frac{z-y}{a-b};\quad \:a\ne \:b[/tex]

Therefore, the solution for x will be:

[tex]x=\frac{z-y}{a-b}[/tex]

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]

Answer:

30.85

Step-by-step explanation:

1. Put the 12.34 on top to make things simpler

then just multiply each number as if the decimals weren't there to begin with.

Your answer should look way too big, but when you finish multiplying count how many decimal places were in the two numbers, for this it would be 3 since there is a 5, 3, and 4 behind the decimal places.

You have to count 3 decimal places in your final answer to get the right solution! Any 0's trailing behind can be removed as well.

Hope this helps!!!

Answer: 30.85

Step-by-step explanation:

This is the answer because you have to straight up your decimal so you can multiply your numbers up right and every time you get ready to add you suppose to add a extra zero.

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

Answer:

9

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
