Answer:

Shorter leg=3

Longer leg=4

Step-by-step explanation:

Equations

In a right triangle, Pythagora's Theorem is satisfied. Being a the hypotenuse, b and c the legs of the triangle, then:

[tex]a^2=b^2+c^2[/tex]

Let's call

x=the shorter leg of the triangle

The longer leg is 1 cm longer than the shorter leg, thus:

x+1=the longer leg.

Since the hypotenuse is 5 cm long:

[tex]5^2=x^2+(x+1)^2[/tex]

Operating:

[tex]25=x^2+x^2+2x+1[/tex]

Swapping sides and simplifying:

[tex]2x^2+2x+1=25[/tex]

Subtracting 25:

[tex]2x^2+2x-24=0[/tex]

Dividing by 2:

[tex]x^2+x-12=0[/tex]

Factoring:

[tex](x-3)(x-4)=0[/tex]

We have two possible solutions:

x=3, x=4

The longer leg is x+1.

If x=3, x+1=4

If x=4, x+1=5. This solution is not valid because one leg would be equal to the hypotenuse.

Thus, the solution is:

Shorter leg=3

Longer leg=4

Answer:

Min value of F = 24

It happens when m = 3 and a = 4.

==========================================================

Explanation:

Start with ma = 12 and Solve for 'a'  to get a = 12/m

Plug it into the other equation to get

F = 3a + 4m

F = 3(12/m) + 4m

F = 36/m + 4m

F = 36/m + (4m^2)/m

F = (36+4m^2)/m

The equation above is in the form F = a/b where a = 36+4m^2 and b = m

Applying derivatives to each piece gives a' = 8m and b' = 1

So,

F = a/b

F ' = (a/b)'

F ' = (a' * b - a * b')/(b^2) .... quotient rule

F ' ( 8m*m - (36+4m^2)*1 )/(m^2)

F ' = (8m^2 - 36 - 4m^2)/(m^2)

F ' = (4m^2 - 36)/(m^2)

---------------------

The minimum of F occurs when F ' = 0

F ' = 0

(4m^2 - 36)/(m^2) = 0

4m^2 - 36 = 0*m^2

4m^2 - 36 = 0

4m^2 = 36

m^2 = 36/4

m^2 = 9

m = sqrt(9) or m = -sqrt(9)

m = 3 or m = -3

Keep in mind that m > 0, so we ignore m = -3

---------------------

Next we'll use the first derivative test. I find it's easier compared to the second derivative test because we don't have to do another derivative.

The function F(m) = (36+4m^2)/m has a potential min point at m = 3.

To see if we have an actual min point or not, we need to check the sign of F ' (m) when m = 2 and m = 4; that way we see if F ' (m) changes sign as we pass through m = 3.

First compute the derivative when m = 2

F ' (m) = (4m^2 - 36)/(m^2)

F ' (2) = (4(2)^2 - 36)/(2^2)

F ' (2) = (4*4-36)/(4)

F ' (2) = (16-36)/(4)

F ' (2) = -20/4

F ' (2) = -5

The actual value doesn't matter. All we're after is the sign of it. So we see that F ' (2) is negative which means we know that F(m) is decreasing when 0 < m < 3

Now let's try m = 4

F ' (m) = (4m^2 - 36)/(m^2)

F ' (4) = (4(4)^2 - 36)/(4^2)

F ' (4) = (4*16-36)/(16)

F ' (4) = (64-36)/(16)

F ' (4) = 28/4

F ' (4) = 7

This value is positive, so F(m) is increasing on the interval 0 < m < infinity

F(m) decreases on 0 < m < 3 and increases on  3 < m < infinity

So the F function goes downhill and then goes back uphill, and this lowest valley point is when m = 3

So we've confirmed that F(m) does indeed have a min value at m = 3.

Making a sign chart or interval might help visualize it.

---------------------

Now onto the last part.

Plug m = 3 into F(m) to find the min value of F

F = (36+4m^2)/m

F = (36+4*3^2)/3

F = (36 + 4*9)/3

F = (36 + 36)/3

F = 72/3

F = 24

The smallest F can get is 24 and it happens when m = 3 and a = 12/m = 12/3 = 4.

------------------------------

Side note: A non-calculus approach would have you graphing y = (36+4x^2)/x, and then using the graphing calculator to find the lowest point in the first quadrant. We're in this quadrant since a, m and F are all positive.

Answer:

a. 40С10 * 20С10 / 60С20

b. 1 + (40)(20) + (40C2)(20C2) / 60С20

Step-by-step explanation:

Total number of application = 60

Total number of application from east = 40

Total number of application remaining = 20

Number of ways of selecting 20 applicant = 60C20 (Sample space)

a. Probability of 10 are from East.

= (10 from east) * (10 from remaining)

= 40С10 * 20С10 / 60С20

b. Probability of Not more than 2 are from East.

= P(x≤2)

= P(x=0) + P(X=1) + P(X=2)

= [40С0 * 20С20 / 60С20] + [40С1 * 20С19 / 60С20] + [40С2 * 20С18 / 60С20]

= 1 + (40)(20) + (40C2)(20C2) / 60С20

Answer: it’s b because if you times that by anything it will always be a product I think

Answer:

There are 24 right handed students

Step-by-step explanation:

This is a ratio question so it would be represented as 1:4.

First you would do 1 + 4 which is 5.

Then do 30 ÷ 5 which is 6.

Finally multiply 6 by 4 and 1.

So 6 × 4 × 1 is 24.

So there are 24 students who are right handed.

Hope this makes sense!

Answer:

$142.86

Step-by-step explanation:

In order to know the original price of the sound bar, it is best to write the problem above into a mathematical sentence first.

Given: $30 = the amount you were able to save

          21% = the discount (this means that $30 is the 21% discount)

Let x be the original price of the sound bar.

The mathematical sentence is:

$30 is 21%(0.21) of x

x=[tex]\frac{30}{0.21}[/tex]

x= $142.857 or $142.86 (once rounded off to the nearest hundredths)

So, the original price of the sound bar before the discount is $142.86

Answer:

(- 2x , - 2y)

Step-by-step explanation:

A(x, y) ----> A' (kx, ky)

~~~~~~~~

H(- 1 ,1) ----> [k(- 1), k(1)] ----> G(2, - 2) ⇒ k = - 2

M( - 1.5, - 4) -----> [(- 2)(- 1.5) , (- 2)(- 4)] ------> R(3. 8)

k = - 2

Thus, the rule of dilation centered in origin is (- 2x , - 2y)

Answer:

As per graph the rate of Printer A is 15 pages per minute.

Missing words are:

The rate for Printer B is greater than the rate for Printer A because the rate of 25 pages per minute is greater than the rate of 15 pages per minute for Printer A.

Step-by-step explanation:

let the length be =L

the width is 4 × the length

so the width will be 4L

the formular for the perimeter of a rectangle is =2(L +W)

170=2(L +4L)

170=2(5L)

170=10L

17=L

so the width is 4 × the length

17×4

=68

L=17

W=68

Answer:

4.1 hours

Step-by-step explanation:

Laura spent 4.1 more hours on her project than Alexander spent on his. If we split each number into 2 parts (like this: 12.5 -> 12 and .5; 16.6 -> 16 and .6) then we can subtract 12 from 16 and .5 from .6 to get 4 and .1. we add those together to get 4.1

The Graph Shifts 4 units up

Step-by-step explanation:

Okay so, when you add four to a graph in this manner we have to look at the equation as a whole. f(x)=mx+b + 4. By adding four we are changing the y-intercept and shifting it up four. This will cause the entire graph to shift upwards four spaces.

Answer:

20 tickets each will have to bought with fast pass so that the total cost is equal to that of each other.

Step-by-step explanation:

Entry fee for The Great Adventure theme park = $15

Charge for fast pass at each ride = $1.50

Entry fee for The Big Thicket amusement park = $15

Charge for fast pass at each ride = $1.00

Let the number of ride tickets purchased with Fast pass = [tex]x[/tex]

As per question statement, the total cost at each will be equal to that of each other.

Writing in the equation form, we get:

$15 + $1.50 [tex]\times[/tex] [tex]x[/tex] = $25 + $1.00 [tex]\times[/tex] [tex]x[/tex]

[tex]\Rightarrow 1.50x -1.00x = 25 -15\\\Rightarrow 0.50x = 10\\\Rightarrow x = 20[/tex]

Therefore, 20 tickets each will have to bought with fast pass so that the total cost is equal to that of each other.
