Answer:
A1: a=4
A2: a=12
A3: p=18
Step-by-step explanation:
a= 1/2 4 * 2
= 4
a = 1/2 6 * 4
= 12
to find p add all sides
P= 6 + 6 + 6 = 18
Taco Quatro can make their entire menu out of their fantastic four Mexican ingredients, cheese, meat, beans and tortillas. A Nacholupa (N) needs 2 ounces of cheese, 4 ounces of beans and 3 tortillas. A Quesatilla (Q) needs 4 ounces of cheese, 2 ounces of meat and 1 tortilla. An Enchinacho (E) requires 2 ounces each of cheese, meat, and beans plus 3 tortillas. Their newest menu item, the Burritaco (B) needs 4 ounces of cheese, 2 ounces of meat and one tortilla. A Nacholupa sells for $2.75, a Quesatilla sells for $2, an Enchinacho sells for $3 and the new Burritaco sells for $4. The assistant manager checks the cooler one fine Monday morning and sees that they have 400 ounces of cheese, 150 ounces of meat, 400 ounces of beans and 250 tortillas on hand. Then how many units of each product should be produced to maximize the revenue
Answer:
The solution is:
z (max ) = 446.25 $
x₁ = 55 x₂ = 0 x₃ = 5 x₄ = 70
Step-by-step explanation:
From problem statement:
Nacholupa Quesatilla Enchinacho Burritaco
x₁ x₂ x₃ x₄
Cheese 2 4 2 4
meat 0 2 2 2
beans 4 0 2 0
Tortillas 3 1 3 1
Price $ 2.75 2 3 4
From table :
z = 2.75*x₁ + 2*x₂ + 3*x₃ + 4*x₄ to maximize
Subject to:
Availability of cheese: 400 ou
2*x₁ + 4*x₂ + 2*x₃ + 4*x₄ ≤ 400
Availability of meat : 150 ou
2*x₂ + 2*x₃ + 2*x₄ ≤ 150
Availability of beans : 400 ou
4*x₁ + 2*x₃ ≤ 400
Availability of tortillas : 250
3*x₁ + x₂ + 3*x₃ + x₄ ≤ 250
General constraints:
x₁ ≥ 0 x₂ ≥ 0 x₃ ≥ 0 x₄ ≥ 0
All integers
With the use of AtomZmath ( integer solving on-line software )
The solution is:
z (max ) = 446.25 $
x₁ = 55 x₂ = 0 x₃ = 5 x₄ = 70

Question 13 I don’t know how to do it
Answer:
y = - [tex]\frac{1}{4}[/tex] (x - 1)²(x + 2)(x + 6)
Step-by-step explanation:
The roots from the graph are
x = - 6 , then factor is (x + 6)
x = - 2 , then factor is (x + 2)
x = 1 ( multiplicity 2 ) , then factor is (x - 1)² then
y = a(x - 1)²(x + 2)(x + 6) ← a is a multiplier
To find a substitute any point on the graph into the equation
Using (0, - 3 ), then
- 3 = a(- 1)²(2)(6) = 12a ( divide both sides by 12 )
- [tex]\frac{1}{4}[/tex] = a
Then
y = - [tex]\frac{1}{4}[/tex] (x - 1)²(x + 2)(x + 6)

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the
time after launch, x in seconds, by the given equation. Using this equation, find the
time that the rocket will hit the ground, to the nearest 100th of second.
y = -16x^2+ 181x + 59
Answer:
The rocket will hit the ground after about 11.63 seconds.
Step-by-step explanation:
A rocket is launched from a tower. Its height y in feet after x seconds is modeled by the equation:
[tex]y=-16x^2+181x+59[/tex]
We want to determine the time at which the rocket will hit the ground.
If it hits the ground, its height y above the ground will be 0. So, we can set y = 0 and solve for x:
[tex]0=-16x^2+181x+59[/tex]
Solve the quadratic. Factoring is too tedious or impossible, and completing the square is also very tedious. So, we can use the quadratic formula:
[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
In this case, a = -16, b = 181, and c = 59. Substitute:
[tex]\displaystyle x=\frac{-(181)\pm\sqrt{(181)^2-4(-16)(59)}}{2(-16)}[/tex]
Evaluate:
[tex]\displaystyle x=\frac{-181\pm\sqrt{36537}}{-32}[/tex]
Simplify:
[tex]\displaystyle x=\frac{181\pm\sqrt{36537}}{32}[/tex]
Hence, our solutions are:
[tex]\displaystyle x=\frac{181+\sqrt{36537}}{32}\approx 11.63\text{ or } x=\frac{181-\sqrt{36537}}{32}\approx-0.32[/tex]
Since time cannot be negative, we can ignore the second solution.
So, the rocket will hit the ground after about 11.63 seconds.

Step-by-step explanation:
SOHCAHTOA
sinθ = opposite / hypotenuse
cosθ = adjacent / hypotenuse
tanθ = opposite / adjacent
10. tan64° = 42 / x ; x = 42 / tan64° ; x = 20.48476872
12. sin54° = BD / 20 ; BD = 20 * sin54° ; BD = 16.18033989 ;
tan28° = BD / DC ; DC = BD / tan28° ; DC = 30.43079344
13. tan51° = JL / 14 ; JL = 14 * tan51° ; JL = 17.28856019 ;
cos72° = KL / JL ; KL = JL * cos72° ; KL = 5.342458907

Graph the equation below using the slope and y-intercept form.
Answer:

The passing yards for the top 5 quarterbacks in the country are 3,832, 3,779, 3,655, 3,642, and 3,579. Find the variance and standard deviation. Round to the nearest hundredth. EXPLAIN WORK
First get the average passing yards:
(3,832 + 3,779 + 3,655 + 3,642 + 3,579) / 5 = 3,697.4
Now get the squared residuals for each quarterback's passing yards. That is, compute the difference between each data and the average, then square the result. For example,
(3,832 - 3,697.4)^2 = 134.6^2 = 18,117.2
For the others, you should get squared residuals of
6,658.56
1,797.76
3,069.16
14,018.6
Take the sum of the squared residuals, then - since this is a sample, and not a population of all quarterbacks - divide the sum by 5 - 1 = 4 to get the variance:
(18,117.2 + 6,658.56 + 1,797.76 + 3,069.16 + 14,018.6)/4 = 10,915.3
The standard deviation is just the square root of the variance:
√(10,915.3) ≈ 104.48

the answer is 3697.4
