Answer:
2.25 -0.25 increasing (-0.25,2.25)
Step-by-step explanation:
The minimum and maximum values are negative 1/4 and 9/4. In the interval of (0, π/2), the function is decreasing. And the range of the function will be [–1/4, 9/4].
What is a sinusoidal Function?It is a function that repeats itself in a particular time interval.
The equation is given as
y = A sin (ωx + Ф) + C
Where A is the amplitude, ω is the frequency, Ф is the phase difference, and C is the constant.
The function is given below.
f(x) = (5/4) sin(x) + 1
Compare the function with standard equation.
A = 5 / 4
ω = 1
Ф = 0
C = 1
Then the maximum value of the function at sin x = 1, will be
Maximum value = 5/4 + 1
Maximum value = 9/4
Then the minimum value of the function at sin x = –1, will be
Minimum value = –5/4 + 1
Minimum value = –1/4
In the interval of (0, π/2), the function is decreasing.
And the range of the function will be [–1/4, 9/4].

Step-by-step explanation:
Shanice's school made $850 by selling 125 tickets to the annual talent show. They sold adult
tickets for $10 and student tickets cost $6. How many adult tickets did they sell? How many
student tickets did they sell?
Write a system of equations to represent this situation. Define your variables.
Answers
Let A = adult
First equation is total tickets
Second should be the cost
S + A = 125
6S + 10A = 850
Use substitution or elimination
S + A = 125
S = -A + 125
I used substitution
6(-A + 125) + 10A = 850
-6A + 750 + 10A = 850
4A + 750 = 850
4A = 100, A = 25 adult tickets
125 - 25 = 100
Solution: 100 student tickets
Answer:
25 adult tickets were sold and 100 student tickets were sold.
Step-by-step explanation:
Let the number of adult tickets sold be x and the number of student tickets sold be y.
We know that the total amount collected from the tickets was $850, and that a total of 125 tickets were sold. We can use this information to come up with two equations.
10x + 6y = 850 - Equation 1
x + y = 125 - Equation 2
Then, use the substitution method to solve for either x or y first, followed by the other.
From equation two:
x + y = 125
x = 125 - y - Equation 3
Sub eqn 3 into eqn 1:
10(125-y) + 6y = 850
1250 - 10y + 6y = 850
1250 - 4y = 850
-4y = - 400
y - 100
Sub y = 100 into eqn 2:
x + 100 = 125
x = 25
Check:
10(25) + 6(100) = 850

To find:
The [tex]m\angle FHG[/tex].
Solution:
We know that all interior angles of a square are right angles.
[tex]m\angle EHG=90^\circ[/tex] (Right angle)
The diagonals of square are always the angle bisectors.
FH is a diagonal of the square. So, it bisects the angle EHG.
[tex]m\angle FHG=\dfrac{m\angle EHG}{2}[/tex]
[tex]m\angle FHG=\dfrac{90^\circ}{2}[/tex]

Part B: Show that one of your expressions in Part A is equivalent to the given expression using algebraic properties. Explain which properties you used. (4 points)
Part C: Show that your other expression from Part A is equivalent to the given expression by substituting a number for m. (3 points)
Answers
Answer:
24m + 12 - - - (1)
12(2m + 1) - - - (2)
Step-by-step explanation:
Given the expression :
4(m + 3 + 5m)
Equivalent expressions include :
24m + 12 - - - (1)
12(2m + 1) - - - (2)
Using algebaraic properties :
4(m + 3 + 5m)
We can expand :
4m + 12 + 20m
4m + 20m + 12
24m + 12
Hence,
4(m + 3 + 5m) = 24m + 12
Using Substitution:
Let m = 5
4(m + 3 + 5m)
4(5 + 3 + 5(5))
4(5 +3 + 25)
4(33)
= 132
12(2m + 1)
12(2(5) + 1)
12(10 + 1)
12(11)
= 132

Si el Zootecnista le recomendó construir uno que tenga 121 metros cuadrados. ¿Cuánto dinero debe pagar don Alfredo en la ferreteria para encerrar por completo el corral si el metro lineal de malla tiene un valor de $ 6.200 el metro?
Answers
Answer:
Don Alfredo debe pagar $272,200 para encerrar por completo el corral.
Step-by-step explanation:
Dado que Don Alfredo quiere construir un corral cuadrado para sus gallinas, utilizando metros de malla lineal para rodearlo, si el zootecnista le recomendó construir uno que tenga 121 metros cuadrados, para determinar cuánto dinero debe pagar don Alfredo en la ferretería para encerrar por completo el corral si el metro lineal de malla tiene un valor de $ 6.200 el metro se deben realizar los siguientes cálculos:
121 metros cuadrados = √121 = 11 (x 11) = 11 x 4 = 44 metros lineales
44 x 6,200 = X
272,800 = X
Por lo tanto, Don Alfredo debe pagar $272,200 para encerrar por completo el corral.

The box plot show the price of textbooks at a local high school. What range describe the middle 50% if the price (p) of the textbooks?
Answers
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the box plot is not attached.
However, the interpretation of the question is to determine the inter-quartile range (IQR) ; this represents the middle 50% of scores
To answer this question, I will make use of the attached box plot.
IQR is calculated as:
[tex]IQR = Q_3 - Q_1[/tex]
[tex]Q_1[/tex] and [tex]Q_3[/tex] are represented by the vertical edges of the rectangle in the box plot. [See attachment]
Reading [tex]Q_1[/tex] and [tex]Q_3[/tex], we have:
[tex]Q_1 = 37[/tex]
[tex]Q_3 = 50[/tex]
The IQR is:
[tex]IQR = 50 - 37[/tex]
[tex]IQR = 13[/tex]
Hence, the range that describes the middle 50% of the attached plot is 13
