Answer:
Discrete
Step-by-step explanation:
Given the function:
f(x) = 100x + 300
Where ;
x = number of attendees
At least 4 students but no more than 9 students will attend the fieldtrip due to transportation and chaperone restrictions
Range of attendees :
4 ≤ x ≤ 9
Is this a discrete or continuous situation?
It is a discrete because the number of students who will attend the science weekend are finite and countable.
The number of attendees range from:
4, 5, 6, 7, 8 and 9.

3x-3 (x+ 1) = 3
Answer:
The answer is~ no solution
Step-by-step explanation:
its no solution because
3x−3(x+1)=3
Step 1: Simplify both sides of the equation.
3x−3(x+1)=3
3x+(−3)(x)+(−3)(1)=3(Distribute)
3x+−3x+−3=3
(3x+−3x)+(−3)=3(Combine Like Terms)
−3=3
−3=3
Step 2: Add 3 to both sides.
−3+3=3+3
0=6

The area of a rectangle is modeled by the graph where y is the area (in square meters) and x is the width (in meters).
What dimensions result in the maximum area?
A rectangle_ meters by_ meters results in the maximum area.
Answer:
The dimensions that result in the maximum area are therefore;
Width = 3.5
Height = 3.5
Step-by-step explanation:
The given parameters are;
The area of the rectangle, y = x × h
Where;
x = The width of the rectangle
h = The height of the rectangle
By examination, we have;
x + h = 7
Therefore, x = 7 - h
Which gives;
y = x × (x - 7) = x² - 7·x
y = x² - 7·x
At x = 0, y = 0
At x = 7, y = 0
However, at x = 1, y = -6
Therefore, the function should be, y = -(x² - 7·x)
The maximum occurs where dy/dx = 0, which gives;
dy/dx = d-(x² - 7·x)/dx = 0
dy/dx = 2·x - 7 = 0
2·x - 7 = 0
x = 7/2 = 3.5
On second derivative, we have;
d²y/dx² = 2, which gives a local minimum
x = 3.5 at maximum height
Which give, the maximum height, [tex]y_{max}[/tex] = -(x² - 7·x) at x = 3.5
∴ [tex]y_{max}[/tex] = -(3.5² - 7×3.5) = 12.25
The maximum height = 12.25
The dimensions that result in the maximum area are therefore;
Width, x = 3.5
Height, h = 7 - x = 7 - 3.5 = 3.5
Height, h = 3.5.
Here goes another question
Answer:
y = x - 8
Step-by-step explanation:
In order to solve this, we need to use point-slope form.:
y - y1 = m(x - x1)
Substitute the numbers into the equation:
y - (-8) = 1(x - 0)
y + 8 = x
y = x - 8
Solve for d in the proportion.
10/15 equals d/12
Answer:
8
Step-by-step explanation:
Since there are two fractions, it is easiest to cross multiply the fractions before doing anything else. Basically:
10/15 = d/12 becomes 120 = 15d.
then you just divide 15 to both sides to get your answer:
d = 120/15, which is the equivalent of d = 8.

Lin read 44 pages in 132 minutes. Diego read 35 pages in 140 minutes. Who is reading at a faster rate, Lin or Diego? Show and Explain your reasoning.
Answer:
Diego
Step-by-step explanation:
divide 132 minutes by 44 pages and you get 3 pages per minute, then divide 140 minutes by 35 pages and you will get 4 pages per minute. so Diego reads 1 more page a minute than lin. hope i helped you :)

The given statement is the scale factor:
[tex]\dfrac{\text{scale distance}}{\text{actual distance}}=\dfrac{1\text{ cm}}{2\text{ m}}[/tex]
This can be rearranged to the formula ...
[tex]\text{actual distance}=\text{(scale distance)}\dfrac{2\text{ m}}{1\text{ cm}}[/tex]
Filling in the given scale distances, you find the actual distances to be ...

60% of a firm's employees are men. Suppose four of the firm's employees are selected. a. What is the random variable we can consider here? b. What is probability of finding three men and one woman? c. What is the answer for part if 75% of employees were men?
Answer:
60% of the employees are men.
Then the 40% left must be women.
4 of them are selected.
a) What is the random variable we can consider here?
A random variable is a variable that can have different outcomes or values, in other words, it is a stochastic variable.
We have a selection of 4 employees at random, then we can define the variable X, that represents (for each employee) the possibility of being man or woman.
b) Probability of 3 men and 1 woman.
Suppose that the selection is in the order:
man-man-man-woman.
We have:
0.6 tree times.
0.4 one time.
P = 0.6^3*0.4
But this is for the case where the woman is in the last selection, it can be in the first, second and third, then we have 4 permutations, the actual probability is:
P = 4*( 0.6^3*0.4) = 0.3456.
c) If now we have tat 75% are men, then 25% are women.
Now we can do the same as before, but now the probability for a man is 0.75 and for a woman is 0.25, then the previous equation is now:
P = 4*(0.75^3*0.25) = 0.421875
(a) The random variable will be "Men percentage".
(b) The probability of finding 3 men and one woman be "0.3456".
(c) The probability be "0.4219".
Probability(a) A random variable represents a variable which might have several occurrences as well as quantities; it is indeed a stochastic quantity.
If we choose four workers at random, users may create the variable X, which reflects the potential of someone being a male or even a woman.
(b) The probability be:
→ P(3 men and women) = [tex]4C_3[/tex] (0.6)³ (1 - 0.6)¹
= 0.3456
(c) The probability be:
→ P(3 men and women) = [tex]4C_3[/tex] (0.75)³ (1 - 0.75)¹
= 0.4219
Thus the response above is correct.

Step-by-step explanation:
The height above the surface of the Earth (in meters) of a rock thrown into the air at 10 m/s after x seconds is given by f(x)=−9.8x2+10x+1.5. On the surface of the moon, the height is given by g(x)=−1.6x2+10x+1.5. How much higher does the rock travel on the moon than on Earth? The rock travels about __ meter(s) higher on the moon than on Earth.
Answer:
Rock travels about 8.2x²meters higher on the moon than on the Earth.
Step-by-step explanation:
Expression showing the height of a rock thrown into the air at Earth is,
f(x) = -9.8x² + 10x + 1.5
Similarly, expression showing the height of rock thrown on the moon is,
g(x) = -1.6x² + 10x + 1.5
Difference in the height of the rock thrown on moon = g(x) - f(x)
= (-1.6x² + 10x + 1.5) - ( -9.8x² + 10x + 1.5)
= -1.6x² + 9.8x² + 10x - 10x + 1.5 - 1.5
= 8.2x²
Therefore, rock travels about 8.2x²meters higher on the moon than on the Earth.

Write a recursive rule for the sequence 4,10,16,22
Answer:
[tex]a_{n+1}[/tex] = [tex]a_{n}[/tex] + 6
Step-by-step explanation:
The terms have a common difference d between consecutive terms, that is
10 - 4 = 16 - 10 = 22 - 16 = 6
To obtain the next term add 6 to the previous term ( recursive rule ), thus
[tex]a_{n+1}[/tex] = [tex]a_{n}[/tex] + 6 with a₁ = 4

4) The triangle on the right is an equilateral
Find the value of X and Y
Answer:
angle Y is 29 degrees
angle X is 120 degrees
Step-by-step explanation:
Well, if the triangle is an equilateral, then all the angles are equal to
60 degrees
that means the the angle at the top point is 60+31 = 91 degrees
the right point is 60 degrees
every triangle has 180 degrees total
180 - (91+60) = 29 degrees
NOW FORGET ABOUT THE EQUILATERAL FOR A BIT
180 = 31+x+29
simplify
180 = 60+x
subtract 60 from both sides
120 = x

What is the solution to the following system of equations?
X - 3y = 5
2x + y = 10
(5,0)
(0,5)
(7,0)
(0,7)
Answer:
( 5, 0 )Step-by-step explanation:
x - 3y = 5
2x + y = 10 multiply by 3 to eliminate y and solve for x
x - 3y = 5
6x + 3y = 30 then add
7x = 35
simplify:
x = 35 / 7
x = 5
substitute x = 5 back into the eq.2
2x + y = 10
2(5) + y = 10
y = 10 - 10
y = 0
therefore the answer is ( 5, 0 )

Write a linear function f with f(-4) = 2 and f(6) =-3
Answer:
f(x) = - [tex]\frac{1}{2}[/tex] x
Step-by-step explanation:
The standard form for a linear function is
f(x) = ax + b
Using the given values f(- 4) = 2 and f(6) = 3 , then
- 4a + b = 2 → (1)
6a + b = - 3 → (2)
Subtract (2) from (1) term by term to eliminate b
- 10a = 5 ( divide both sides by - 10 )
a = - [tex]\frac{1}{2}[/tex]
Substitute a = - [tex]\frac{1}{2}[/tex] into either of the 2 equations and solve for b
Substituting into (1)
2 + b = 2 ( subtract 2 from both sides )
b = 0
Thus the linear function is
f(x) = - [tex]\frac{1}{2}[/tex] x
The linear function is f(x) = -0.5x
For f(-4) = 2
x₁ = -4, y₁ = 2
For f(6) = -3
x₂ = 6, y₂ = -3
The slope(m) is found using the formula
m = (y₂ - y₁)/(x₂ - x₁)
m = (-3-2)/(6-(-4))
m = -5/10
m = -0.5
Substitute m = -0.5, x₁= -4, and y₁ = 2 into the equation below:
y - y₁ = m(x - x₁)
y - 2 = -0.5(x - (-4))
y - 2 = -0.5(x + 4)
y - 2 = -0.5x - 2
y = -0.5x - 2 + 2
y = -0.5x
Therefore, the linear function is f(x) = -0.5x
