By writing an inequality and then converting it to an absolute value equation, we will see that the correct options are C and E.
How to find an inequality?
To find the inequality, we need to find the lower and upper bounds.
First, we know that the machine fills the cups with 4 oz of yogurt, so this is the minimum value allowed, we will have:
4 ≤ x
Then we can add toppings to a maximum value of 6 ounces, this will be the maximum, then we have:
4 ≤ x ≤ 6
We can also write this an absolute value equation, we define:
m = half of the difference of the bounds.M = lower bound + mThen the absolute value equation is:
|x - M| ≤ m
By replacing what we found before, we have:
m = (6 - 4)/2 = 1M = 4 + 1 = 5So the absolute value equation is:
|x - 5| ≤ 1
Finally, we can conclude that the correct options are C and E.

Geometry Question Please Help!!!!
The vertex of a parabola is (-2, -20), and its y-intercept is (0, -12).
The equation of the parabola is y =
x2 +
x +
.
The equation of the parabola with a vertex at (-2, -20) and a y-intercept at (0, -12) is y = 2x^2 + 8x - 12.
Explanation:To find the equation of the parabola, we can use the vertex form of a parabola's equation, which is y = a(x - h)^2 + k, where (h, k) is the vertex of the parabola, and 'a' is a coefficient that determines the parabola's width and direction. Since we have the vertex (-2, -20) and the y-intercept (0, -12), we can plug in these values to solve for 'a':
y = a(x - (-2))^2 - 20
Using the y-intercept:
-12 = a(0 - (-2))^2 - 20
-12 = 4a - 20
8 = 4a
a = 2
The equation of the parabola is therefore:
y = 2(x + 2)^2 - 20
Expanding the equation:
y = 2(x^2 + 4x + 4) - 20
y = 2x^2 + 8x + 8 - 20
y = 2x^2 + 8x - 12
The final quadratic equation of the parabola is:
y = 2x^2 + 8x - 12
If (-3)^-5 =1/x, what is the value of x?
Please help! Given b = 4 and h = 1, what is the equation of the graph if the parent function is y = sqrt x?
A. y = sqrt (4x - 4)
B. y = sqrt (4x + 4)
C. y = - sqrt (4x - 4)
D. y = - sqrt (4x + 4)
To solve this problem, we make use of the formula:
y = a sqrt (b (x – h)) + k ---> 1
Since we are given the parent function:
y = sqrt (x) ---> 2
Then this automatically means that:
a = 1 and k = 0
So going back to equation 1 at a = 1 and k = 0:
y = 1 sqrt (b (x – h))
Since it is given that, b = 4 and h = 1, therefore:
y = sqrt (4 (x – 1))
y = sqrt (4 x – 4)
Answer:
A. y = sqrt (4 x – 4)

Explain in terms of the unit circle and geometry why the trig identity cos2 x + sin2 x = 1 holds true for all values of x.
PLEASE I NEED HELP ASAP
We can imagine the given equation cos2 x + sin2 x = 1 to be in the form of the hypotenuse equation.
Where cos x and sin x is the base and height of the triangle and 1 is the hypotenuse.
Since 1 is the hypotenuse, it also indicates to the radius of the circle. Supposing that the center of the circle is at the origin, then at all values of x (at all values of the angle), the radius of the circle will always be the same which is equal to 1.
Therefore the equation cos2 x + sin2 x = 1 holds to be true for all values of x for a unit circle.

How do you write 56% as a fraction in simplest form?
We can write 56% as a fraction to the simplest form as [tex]\mathbf{= \dfrac{14}{25} }[/tex]
A fraction is a numeric value divided into two parts, the upper part(numerator) and the lower part(denominator) which are separated by a division line.
From the given information:
56% can be written in fraction as [tex]\mathbf{\dfrac{56}{100}}[/tex]
Now, to its simplest form means to divide the numerator and the denominator to their lowest term. By doing so, we have:
[tex]\mathbf{\dfrac{56}{100}}[/tex]
Divided by (2)
[tex]\mathbf{= \dfrac{28}{50} }[/tex]
Divided by (2)
[tex]\mathbf{= \dfrac{14}{25} }[/tex]
Therefore, we can conclude that 56% as a fraction to the simplest form is [tex]\mathbf{= \dfrac{14}{25} }[/tex] since no other number can go in both the numerator and the denominator.

If x represents the number of months that Fiona is a member of the gym, the equation below can be used to determine C, her total membership fee for that duration of time: 100 + 38x = C Fiona has allocated a maximum of $328 to spend on her gym membership. Which number line shows the possible number of months that Fiona can be a member of the gym?
Answer:
x = 6
Step-by-step explanation:
Given : Fiona decides to join a gym :
A joining fee of $100
A monthly fee of $38
x represents the number of months.
Fiona has allocated a maximum of $328 to spend on her gym membership
Her total membership fee for that duration of time: 100 + 38x = C
Solution :
It is given that Fiona has allocated a maximum of $328 to spend
So, C = $328
Putting this value in equation 100 + 38x = C
⇒[tex]100+38x=328[/tex]
⇒[tex]38x=328-100[/tex]
⇒[tex]38x=228[/tex]

Answer:
Step-by-step explanation:
tanα=height/distance
tanα=h/d
d=h/tanα so
d1=h/tanα and d2=h/tanß
Then the distance between them is:
d=h/tanß-h/tanα, we know that h=1300, α=(90°-71.9°=18,1°), and ß=90°-27.1°=62.9°) so
d=(3100*tan62.9)-(3100*tan18.1) meters

Use the horizontal line test to identify the relation whose inverse is not a function.
The graph 3 whose inverse is not a function.
What is an inverse of a function?The inverse function agrees with the resultant, operates and reaches back to the original function. If you consider functions, f and g are inverse, f(g(x)) = g(f(x)) = x.
Horizontal Line Test :-
Let f be a function. If any horizontal line intersects the graph of f more than once, then f does not have an inverse. If no horizontal line intersects the graph of f more than once, then f does have an inverse.
So, according to the definition, the only graph which follows the rule of horizontal lines test is the graph 3.
Hence, the graph 3 whose inverse is not a function.

Trey's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Trey $4.80 per pound, and type B coffee costs $5.85 per pound. This month's blend used three times as many pounds of type B coffee as type A, for a total cost of $603.45 . How many pounds of type A coffee were used?
Let x = the number of pounds of Type A coffee.
We know that this month's blend used 3 times as many pounds of type B coffee as type A coffee.
Total pounds of coffee = x + 3x
The total cost is:
(cost for Type A)(x) + (cost for Type B)(3x) = $603.45
$4.80x + $5.85(3x) = $603.45
$4.80x + $17.55x = $603.45
$22.35x = $603.45
x = 603.45/22.35 = 27 pounds
