WHY CAN'T ANYONE HELP ME PLEASE?? The Pool Fun Company has learned that, by pricing a newly released Fun Noodle at $3, sales will reach 8000 Fun Noodles per day during the summer. Raising the price to $6 will cause the sales to fall to 5000 Fun Noodles per day. a. Assume that the relationship between sales price, x, and number of Fun Noodles sold, y, is linear. Write an equation in slope-intercept form describing this relationship. Use ordered pairs of the form (sales price, number sold).
Answer:
y = -1000x +11000
Step-by-step explanation:
Given:
(x, y) = (sales price, number sold) = (3, 8000), (6, 5000)
Find:
slope-intercept equation for a line through these points
Solution:
When given two points, it often works well to start with the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
Filling in the given points, you have ...
y = (5000 -8000)/(6 -3)/(x -3) +8000
y = (-3000/3)(x -3) +8000
y = -1000x +3000 +8000 . . . . eliminate parentheses

Step-by-step explanation:
3 5/6 + 1 4/5 since it increased
find the LCD (Least Common Denominator)
that would be 30
3 25/30 + 1 24/30
=4 49/30
= 5 19/30
Then we do subtraction since it lost some weight
5 19/30 - 2 7/15
find LCD again
5 19/30 - 2 14/30
=3 5/30
simplify
3 1/6 kilograms. That's what I think.
In the figure below, ABC is similar to XYZ . What is the length of ZX ? Enter only the number as an integer or decimal. An image shows two similar right triangles, A B C and X Y Z. Triangle A B C is smaller than triangle X Y Z. In triangle A B C, side A B is 2, side B C is 4, and side C A is 3. In triangle X Y Z, side X Y is 7, side Y Z is 14, and side Z X is labeled N.
Given:
Triangle ABC is similar to triangle XYZ.
In triangle ABC AB=2, BC=4, CA=3.
In triangle XYZ, XY=7, YZ=14, ZX=N.
To find:
The length of ZX.
Solution:
If two triangles are similar, then their corresponding sides are proportional.
Since \(\Delta ABC\sim \Delta XYZ\), therefore
\(\dfrac{AB}{XY}=\dfrac{BC}{YZ}=\dfrac{CA}{ZX}\)
\(\dfrac{2}{7}=\dfrac{4}{14}=\dfrac{3}{N}\)
\(\dfrac{2}{7}=\dfrac{2}{7}=\dfrac{3}{N}\)
\(\dfrac{2}{7}=\dfrac{3}{N}\)
On cross multiplication, we get
\(2\times N=3\times 7\)
\(2N=21\)
Divide both sides by 2.
\(N=\dfrac{21}{2}\)
\(N=10.5\)
Therefore, the length of side ZX is 10.5 units.
ASAP, PLSSS!!!! What is the range of the given function?
Answer:
[6, 8).
Step-by-step explanation:
When we are looking for the range of a function by just looking at the graph, we have to define from what point to what point the graph move vertically. On the other hand, if we were looking for the domain, we would state from where to where the graph moves horizontally.
In this case we have to analyze the graph vertically, since we are looking for the range of the function. Therefore, if we take a look at the line we can notice that it goes from y=6 to y=8. Therefore the range should be from 6 to 8.
Now, this result must be expressed in interval notation, meaning that we have to state whether the values of each end are contained or not by the function. The graph already tells us about it., because it marks it with the closed or open dots. In the case of the number 6, we have a closed dot, means that the function contains the number 6. For the other end we have an open dot, means that the function doesn't contain the number 8.
Applying internal notation, the range of this function is:
[6, 8).

Bus 47, with a range of 24
The bus that is the most consistent, given the data collected on travel times to school from two groups of students is C Bus 18, with a range of 10
How to find the consistent bus ?To determine which bus is the most consistent, we should use the interquartile range (IQR) as the measure of variability. The IQR measures the spread of the middle 50% of the data, which makes it less sensitive to outliers compared to the range.
Bus 47:
Median (Q2): 16
Q1: 10
Q3: 22
IQR = Q3 - Q1 = 22 - 10 = 12
Bus 18:
Median (Q2): 12
Q1: 8
Q3: 18
IQR = Q3 - Q1 = 18 - 8 = 10
Bus 18 has a smaller IQR than Bus 47 (10 vs. 12), which means the travel times for Bus 18 are more consistent.
Note: Figures might be different due to options being for different variant but Bus 18 is the most consistent.

For the trigonometric identity
11. If cos 27° = x, then the value of tan 63° interims of "x" is x/√1 - x²
12. If Θ be an acute angle and 7sin²Θ + 3 cos²Θ= 4, then tan Θ is 1/√3
13. The value of tan 80° × tan 10° + sin² 70° + sin² 20° is 2
14. The value of (sin 47°/cos 43°)² + (cos 43°/sin 47°) - 4 cos²45° is 0
15. If 2 (cos²Θ - sin²Θ) = 1, Θ is a positive acute angle them the value of Θ is 30°
16. If 5 tan Θ = 4, then (5 sin Θ - 3 cos Θ)/(5 sin Θ + 2 cos Θ) is equal to 1/6
17. If sin(x + 20)° = cos (x + 10)° then the value of "x" is 30°
18. The value of (sin 65°)/ (cos 25°) is 1
How do we find the various trigonometric identity?To solve the various trigonometric identity;
11. Given: cos 27° = x
We know that cos (90 - θ) = sin θ
So, cos 63° = sin 27°
And sin 63° = √1 - cos²27°
Substituting cos 27° = x, we get
sin 63° = √1 - x²
Therefore, Therefore, tan 63° = sin 63° / cos 63° = cos 27° / cos 63° = x / cos 63°.
= x/√1 - x²
12. Given: Θ is an acute angle and 7sin²Θ + 3 cos²Θ= 4
Since Θ is an acute angle, sin²Θ + cos²Θ = 1
Substituting sin²Θ + cos²Θ = 1 into the equation 7sin²Θ + 3 cos²Θ= 4, we get
7 (sin²Θ/ cos²Θ) + 3 = 4/cos²Θ - 4 sec²Θ
⇒ 7tan²Θ + 3 = 4(1 + tan²Θ)
⇒ 7tan²Θ + 3 = 4 + 4 tan²Θ
⇒3 tan²Θ = 1
⇒ tan²Θ = 1/3
⇒ tanΘ = 1/√3
13. For tan 80° × tan 10° + sin² 70° + sin² 20°
⇒ tan 80° = cot (90 - 80)° = cot 10°
⇒ sin 70° = cos (90 - 70) = cos 20°
⇒ cot 10° × tan 10° + cos 20° + sin² 20°
= 1 + 1 = 2
14. (sin 47°/cos 43°)² + (cos 43°/sin 47°) - 4 cos²45°
= (sin 47°/cos43°)² + (cos 43°/sin 47°)² - 4(1/√2)²
= (sin (90° - 43°)/cos43°)² + (cos (90° - 47°)/sin)² = 4(1/2)
= (cos 43°/cos 43°)² + (sin 47°/ sin 47°)² - 2
= 1 + 1 - 2 = 0
15. 2 (cos²Θ - sin²Θ) = 1
cos²Θ - sin²Θ = 1/2
Since Θ is an acute angle, sin²Θ + cos²Θ = 1
Substituting sin²Θ + cos²Θ = 1 into the equation cos²Θ - sin²Θ = 1/2, we get
cos²Θ - (1 - cos²Θ) = 1/2
2cos²Θ = 3/2
cos Θ = √3/2(cos 30° = (√3)/2
= 30°
16. Given: 5 tan Θ = 4
We know that tan Θ = sin Θ / cos Θ
So, 5 sin Θ / cos Θ = 4
5 sin Θ = 4 cos Θ
Dividing both sides of the equation by 5, we get
sin Θ / cos Θ = 4/5
∴ sin Θ = 4/5 cos Θ
given that the expression is (5 sin Θ - 3 cos Θ)/(5 sin Θ + 2 cos Θ)
we substitute sin Θ = 4/5 cos Θ into the equation
⇒(5 × 4/5 cos Θ - 3 cos Θ)/(5 × 4/5 cos Θ + 2 cos Θ)
= (4-3)/(4 + 2) = 1/6
17. Given: sin(x + 20)° = cos (x + 10)°
We know that sin(90 - θ) = cos θ
So, sin(x - 20)° = sin(90 - (3x + 10))°
⇒ (x - 20)° = (90 - (3x + 10))°
⇒ x - 20° = 90° - 3x + 10
⇒ 4 x = 120°
⇒ x = 120°/4
⇒ x = 30°
18. To find the value of (sin 65°) / (cos 25°), we can use the trigonometric identity:
To solve this, we can use the following trigonometric identities:
sin(90 - θ) = cos θ
cos(90 - θ) = sin θ
We can also use the fact that sin²θ + cos²θ = 1.
Rewrite sin (65°) / cos (25°)
⇒ sin (65°) = cos (25°)
∴ cos (25°)/ cos (25°) = 1

For x between x=4 and x=8 the function of value y is ≥ 0.
How to calculate or determine the slope of a line?In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;
Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope (m) = rise/run
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
By substituting the given data points into the formula for the slope of a line, we have the following;
Slope (m) = (0 - 3)/(3 - 0)
Slope (m) = -3/3
Slope (m) = -1.
For x between x=3 and x=5, the slope is given by;
Slope (m) = (3 + 3)/(5 - 3)
Slope (m) = 6/2
Slope (m) = 3.
By critically observing the graph of this function, we can logically deduce that the function value of y is less than or equal to 0 for x between x=0 and x=4 and greater than or equal to 0 for x between x=4 and x=8.
