Answer:

Dad made 90 steps during that period.

Step-by-step explanation:

Let x,y,z be the steps made by dad,Anna and Todd.

Given that while dad made 3 steps, Anna made 5 steps.

That is [tex]\frac{x}{y}= \frac{3}{5}[/tex]

           [tex]y=\frac{5x}{3}[/tex]

And for every 3 steps Anna made, Todd made 5 steps.

That is [tex]\frac{y}{z}= \frac{3}{5}[/tex]

            [tex]z=\frac{5y}{3} =\frac{5(\frac{5x}{3}) }{3} =\frac{25x}{9}[/tex]

It is also given that total number of steps made by Anna and Todd is 400.

That is y+z=400

let us plugin y and z in terms of x.

       [tex]\frac{5x}{3} +\frac{25x}{9} =400[/tex]

        [tex]\frac{15x}{9} +\frac{25x}{9}=400[/tex]

       [tex]\frac{40x}{9}=400[/tex]

       [tex]x=400X\frac{9}{40} =90steps[/tex]

Hence Dad made 90 steps during that period.

y=4/3x+4

are you in k12 i tookthat test already

y = [tex]\frac{4}{3}[/tex] x + 4

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4 ) and (x₂, y₂ ) = (-3, 0 ) ← 2 points on line

m = [tex]\frac{x0-4}{-3-0}[/tex] = [tex]\frac{-4}{-3}[/tex] = [tex]\frac{4}{3}[/tex]

the line crosses the y-axis at (0, 4 ) → c = 4

y = [tex]\frac{4}{3}[/tex] x + 4 ← in slope-intercept form

3(x + 12) does not, and never will, equal 3(x + 5)

We can solve the equation to verify.

3(x + 12) = 3(x + 5)

Distributive property.

3x + 36 = 3x + 15

Subtract 15 from both sides.

3x + 21 = 3x

Cancel like terms.

21 = 0 × this is incorrect.

Saturn takes 17.6 more years than Jupiter, so 17.6 + 11.9 will get you how long Saturn will take to orbit the sun, which would give you 29.5 years.

The time it takes Saturn to orbit the sun can be calculated by adding Jupiter's orbit time to the additional time Saturn takes after Jupiter. Saturn takes approximately 29.5 years to complete one orbit around the sun.

To find out how long it takes Saturn to orbit the sun, we know that Jupiter takes 11.9 years and Saturn takes 17.6 more years than Jupiter. So, Saturn takes 11.9 + 17.6 = 29.5 years to orbit the sun.

Mila reads at a rate of 2 paragraphs per minute. After reading for 3 minutes, she had read a total of 6 paragraphs.

This situation can be represented with a linear equation written in point-slope form,  

Let 'x' represents the number of minutes and,

y represents the number of paragraphs.  

In one minute Mila reads 2 paragraphs .

So, y=2x

Let x=1 then y=2

x=2 then y =4

Here slope of equation is 2

Let( x1, y1) and (x2,y2) be the two point the equation y=2x the ,

we can write, (y2 - y1) = m(x2 - x1)

or (y2 - y1) = 2(x2 - x1)

Answer:

(3,6)

Step-by-step explanation:

Given that Mila reads at a rate of 2 paragraphs per minute. After reading for 3 minutes, she had read a total of 6 paragraphs.

This situation can be represented with a linear equation written in slope-intercept form,  as

[tex]y=2x[/tex]

where 'x' represents the number of minutes and,

y represents the number of paragraphs.  

Since y intercept is 0 i.e. 0 paras in 0 minutes we have the equation as

[tex]y=2x[/tex]

Since no of minutes or paragraphs cannot take negative values this line is defined only in the I quadrant where both x and y are positive

Out of the points given as follows:

(3,6) (2,3) (-3,6) or (-2,6) ,

we can remove last two since they have negative x which is impossible.

Consider  (3,6) (2,3)

Out of these only I point  (3,6) satisfies  [tex]y=2x[/tex] and second point   (2,3) does not satisfy

[tex]y=2x[/tex]

Hence answer is (3,6)

solution = (4, - 2 )

substitute x = 4 into - y = [tex]\frac{1}{2}[/tex] x

- y = [tex]\frac{1}{2}[/tex] × 4 = 2 ( multiply both sides by - 1 )

y = - 2

solution is ( 4, - 2 )

Answer:

I think it is (4,-2)

since y varies directly with y then

y = kx ( k is the constant of variation )

to find k use y = 3 when x = 2

k = [tex]\frac{y}{x}[/tex] = [tex]\frac{3}{2}[/tex]

equation is : y = [tex]\frac{3}{2}[/tex] x

When x = 1 then y = [tex]\frac{3}{2}[/tex] × 1 = [tex]\frac{3}{2}[/tex]

Polynomial function of grade 5

Given roots: -2, 2,[tex]4 + i[/tex]

Having an imaginary root given by [tex]a + bi[/tex], the other root, in the same imaginary way, must be given by its complex conjugate, that is, [tex]a-bi[/tex].

In this way, the fourth root is given by:

[tex]4-i[/tex]

Since the polynomial function is grade 5, it must have 5 roots. Thus, the fifth root must be given by a real number.

Thus, the roots of the polynomial function are given by: three real roots and two imaginary roots.

Answer:

Option D

f(x) has 3 real roots x = -2, x = 2 and x = 4

complex roots occur in conjugate pairs

x = i is a root then x = - i is a root

there are therefore 2 imaginary roots

f(x) has 3 real roots and 2 imaginary roots

When you factor out -1, you get ...

note that 5π /4 is in the third quadrant where the cos is negative

the related acute angle to 5π /4 is π/4, thus

cos( 5π /4 ) = - cos (π/4 ) = - √2/2

We can also evaluate using the addition formula for cosine

• cos (x + y ) = cosxcosy - sinxsiny

note that 5π /4 = (π + π/4 )

cos(5π /4 ) = cos (π + π/4 )

= cos(π)cos(π/4) - sin(π)sin(π/4)

= - 1 √2/2 - 0 = - √2/2

James will end up with his original t cars and half of (t+13) cars, so will have ...

... t + (t+13/2) = (3t +13)/2 . . . . cars James has after Paul's gift

To find out how many cars James will have after Paul gives him half of his cars, we need to determine the numbers of cars James and Paul have. We then calculate half of Paul's cars and add that to James' original number of cars.

To find out how many cars James will have after Paul gives him half of his cars, we need to first determine how many cars Paul has in total.

We know that Paul has 13 more cars than James, so we can set up an equation:

Paul's cars = James' cars + 13. Next, we need to find out how many cars Paul will give to James, which is half of Paul's cars.

We can set up another equation: cars Paul gives to James = Paul's cars ÷ 2.

Finally, to find out how many cars James will have after Paul gives him half of his cars, we simply add the number of cars Paul gives to James to James' original number of cars.

Let's say James has 5 toy cars. Paul has 13 more, so Paul has 5 + 13 = 18 toy cars.

Half of Paul's cars is 18 ÷ 2 = 9 toy cars. James will have 5 + 9 = 14 toy cars after Paul gives him half of his cars.

Answer:

radius = ((3*Volume) ./ ((2+M).*pi)).^(1/3);

surfaceArea = pi .* radius.^2 .* (2+sqrt(1+M.^2));

Step-by-step explanation:

The OP didn't include this part, but the original problem has the equations written for you in the header. Here they are again:

A = [tex]\pi R^{2}[/tex](2 + [tex]\sqrt{1+M^{2} }[/tex])

V = [tex]\pi R^{3} (2+M)/3[/tex]  where M = H/R

The problem is asking for the surface area of the balloon, but the only values that the user inputs are volume and M. We need to solve for the radius before we can complete the code. So, we can solve for R in one equation and plug it into the second equation.

Let's adapt the given equation V = [tex]\pi R^{3} (2+M)/3[/tex] and solve for R to get the equation for the radius.

V = [tex]\pi R^{3} (2+M)/3[/tex]

3*V = [tex]\pi R^{3} (2+M)[/tex]

[tex]\frac{3*V}{\pi (2+M)} = R^{3}[/tex]

R = [tex](\frac{3*V}{\pi (2+M)})^{1/3}[/tex]

Now, let's convert the equation for R to MATLAB code. Because we are using arrays, each operational symbol must be preceded by a "." unless it is a + or -.

R = [tex](\frac{3*V}{\pi (2+M)})^{1/3}[/tex]

radius = ((3*Volume) ./ ((2+M).*pi)).^(1/3);

Okay, so the hard part is done. The second line of code is easy: all you have to do is transform the given equation for surface area into MATLAB code while using the variable we named "radius" in the last step. Again, because we are performing operations with arrays, use "." in front of all operational symbols (except + and -).

A = [tex]\pi R^{2}[/tex](2 + [tex]\sqrt{1+M^{2} }[/tex])

surfaceArea = pi .* radius.^2 .* (2+sqrt(1+M.^2));

Putting it all together, your answer should be

radius = ((3*Volume) ./ ((2+M).*pi)).^(1/3);

surfaceArea = pi .* radius.^2 .* (2+sqrt(1+M.^2));

By rounding to the nearest whole numbers and estimating, it is confirmed that Ruben's answer of 96.52 ÷ 12.7 equals 7.6 is indeed reasonable.

To assess if Ruben's answer that 96.52 ÷ 12.7 equals 7.6 is reasonable, let's consider the magnitude of the numbers involved. Firstly, we can simplify our estimation by rounding the numbers to the nearest whole digits, which gives us approximately 97 ÷ 13. By using division, we see that 13 goes into 97 about 7 times with some remainder, since 13 x 7 is 91, which is close to 97.

Now, 7.6 is indeed close to our estimation, so we can determine that Ruben's answer is within a reasonable range. Thus, the correct response to whether Ruben's calculation is reasonable would be:

D. Yes, Ruben's answer is reasonable.
