The hypotenuse of a right triangle is 5cm long the longer leg is 1cm longer than the shorter leg find the side lengths of the triangle
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.

A local construction site has workers that are digging the foundation of a new building. They
can haul away 20 lbs every 3.4 minutes while working. If they work for a total of 403
minutes, how many grams of dirt have they taken away? Round to a whole number.
Answer:
The workers can take away 1,075,280 grams of dirt in 403 minutes.
Step-by-step explanation:
[tex]\frac{403}{3.4}*20 = 2,370.588[/tex] pounds in 403 minutes
1 pound = 453.592 grams
2,370.588 * 453.592 = 1,075,280 grams

As per graph the rate of Printer A is 15 pages per minute.
Missing words are:
(a) greater than(b) greater than(c) 15The 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.
For every left-handed person, there are about 4-right handed people. If there are 30 students in a class, predict the number of students who are right-handed.
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!

You want a new sound system to go with your new television. If you saved $30 for the sound bar that had a 21% discount. What was the original price of the sound bar before the discount?
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)

I would say get a small ruler thing and measure them off your screen and say (*Measure off my screen*), then say the distance the dots are from the center point is the same because those dots, when connected to the center point, makes the radius, and the radius stays the same around the circle.
Allyson and Oliver have researched destinations and costs for a class trip. The Great Adventure theme park's entry fee is $15 plus they charge $1.50 at each ride using a Fast Pass. The Big Thicket amusement park charges $25 for its entry fee and $1.00 for each ride using a Fast Pass. To be able to ride all the rides, each student will need a Fast Pass for the day.
How many ride tickets must be purchased with the Fast Pass in order for the total cost at The Great Adventure theme park and The Big Thicket amusement park to be the same?
Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.
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.
