Part VI: Graph the line x+3y=12 by finding the x- and y-intercepts and drawing the line that connects those two points.
Part VII: Use the inequality x+3y>_ 12 to determine whether the line should be solid or dashed and whether you should shade above or below the line you just graphed. Shade the region that satisfies the inequality.
The x intercept and y intercept of the line x + 3y = 12 are (12, 0) and (0, 4) respectively.
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Given the line x + 3y = 12
The y intercept is at x = 0, hence:
0 + 3y = 12
y = 4
The x intercept is at y = 0, hence:
x + 3(0) = 12
x = 12
The x intercept and y intercept of the line x + 3y = 12 are (12, 0) and (0, 4) respectively.

A population of bacteria begins with 1500 bacteria and grows to 4500 in one hour.
- Find a function that represents the growth of this culture of bacteria as a function of time.
- How long does it take this culture of bacteria to double?
Thanks TT
The function that represents the growth of this culture of bacteria as a function of time is; P = 1500e^(1.0986t)
How to calculate Exponential Growth?
The formula for exponential growth is;
P = P₀e^(rt)
where;
P = current population at time t
P₀ = starting population
r = rate of exponential growth/decay
t = time after start
Thus, from our question we have;
4500 = 1500 * e^(r * 1)
4500/1500 = e^r
e^r = 3
In 3 = r
r = 1.0986
Thus, the function that represents the growth of this culture of bacteria as a function of time is;
P = 1500e^(1.0986t)
For the culture to double, then;
P/P₀ = 2. Thus;
e^(1.0986t) = 2
In 2 = 1.0986t
t = 0.6931/1.0986
t = 0.631 hours

Ahanu cuts a board that is 2.25 ft long into two pieces, where one piece is 3 inches longer than the other piece. Find the length of each piece The shorter piece is The longer piece is ft long. ft long. Ahanu cuts a board that is 2.25 ft long into two pieces , where one piece is 3 inches longer than the other piece . Find the length of each piece .
Answer:
The shorter piece is 1.5 ft long.
The longer piece is 1.75 ft long.
Step-by-step explanation:
We are given that one piece is 3 inches longer than the other, which we can convert to 0.25 ft. We are also told that the total length of the board is 2.25 ft. This means that the two pieces must have lengths that add up to 2.25 ft.
Therefore, we can set up the equation:
x + (x + 0.25) = 2.25
Solving for x, we find that x = 1.5 ft, which is the length of the shorter piece. The length of the longer piece must then be 1.75 ft.

show the parabola please
The vertex of the given parabola is the point (3, 25).
How to get the vertex of the parabola?
If the parabola has roots x₁ and x₂, then the vertex of the parabola is at:
xₙ = (x₁ + x₂)/2
Here the parabola is:
y = (-2 - x)*(x - 8)
We can rewrite that to:
y = -(x + 2)*(x - 8)
Then the two roots are:
x = -2 and x = 8
Then the vertex is at:
xₙ = (8 - 2)/2 = 6/2 = 3
To get the y-value of the vertex, we evaluate the equation in x = 3:
y = -(3+ 2)*(3 - 8) = -5*(-5) = 25
The vertex is (3, 25).

What is the slope-intercept equation of the line below?
Answer:
D
Step-by-step explanation:
We will use the 2 coordinates marked on the graph as the reference.
The coordinates are:
A(4,-2)
B(0,3)
We know that the standard form for equation of line is:
y = mx+c
where m is the slope of the equation
and c is the y-intercept.
Very clearly, the y-intercept is where the line intercepts the y line.
and in this case, y-intercept = c = 3.
Now we know that the equation of line is now
y = mx + 3
To find m, the slope, we can use the 2 above coordinates.
slope of line = [tex]\frac{y1-y2}{x1-x2} \\=\frac{-2-3}{4-0} \\=\frac{-5}{4} \\=-\frac{5}{4}[/tex]
(Note: There is a 2nd way to find the slope in this case, let me know if you are interested to find out.)
Equation of line: [tex]y=-\frac{5}{4} x+3[/tex]

Pretend that you are the owner of a candy store. You have twenty pounds of cashews, which cost $3.55 a pound, and you have some peanuts, which cost $2.50 a pound. How many pounds of peanuts would you have to mix with the cashews to get a mixture that costs $3.20 per pound?
A. 10 pounds B. 9 pounds C. 7 pounds D. 8 pounds
Answer:
10 pounds
Step-by-step explanation:
So you have some given information:
(Price of cashews per pound) = 3.55
(Amount of cashes) = 20 pounds
(Price of peanuts, per pound) = 2.50
Now what you're looking for is the amount of peanuts you need to get a mixture of 3.20 per pound. So to find the price per pound. You would take the entire price and divide it by the amount of pounds. So generally it can be expressed as: [tex]\text{price per pound} = \frac{\text{price}}{\text{pounds}}[/tex] . In this equation we know we already have 20 pounds of cashews and they cost 3.55 per pound. We also know what the price per pound of the mixture is going to be, it's going to be 3.20. In the equation I'll express the amount of peanuts as "P" So we have the equation:
Plug in known values:
[tex]3.20 = \frac{20(3.55) + P(2.50)}{20+P}[/tex]
Multiply:
[tex]3.20 = \frac{71 + 2.5P}{20+P}[/tex]
Multiply both sides by 20 + P
[tex](20+P)(3.20) = 71+2.5P[/tex]
Distribute the 3.20
[tex]64+3.2P = 71+2.5P[/tex]
Subtract 2.5 from both side and subtract 64 from both sides
[tex]0.7P = 7[/tex]
Divide both sides by 0.7
[tex]P = 10[/tex]
So 10 pounds will be needed

The arc length is 0.785 units and the diagonal is √2 units
How to determine the lengths?The question requires that we determine the lengths of the blue line and the arc
The blue line is the diagonal of the square, whose side length (l) is
l = 1
The diagonal is then calculated as:
[tex]d = l * \sqrt 2[/tex]
This gives
[tex]d = 1 * \sqrt 2[/tex]
[tex]d = \sqrt 2[/tex]
The diagonal divides the vertex of the square into 45 degrees a piece, and the diagonal represents the radius of the arc
This means that:
[tex]r = \sqrt 2[/tex]
[tex]\theta = 45^o[/tex]
The arc length is:
[tex]l = \frac{\theta}{360} * \pi r^2[/tex]
So, we have:
[tex]l = \frac{45^o}{360} * 3.14 * \sqrt 2^2[/tex]
This gives
[tex]l = \frac{282.6}{360}[/tex]
Divide
l = 0.785
Hence, the arc length is 0.785 units and the diagonal is √2 units

A suspension bridge with weight uniformly distributed along its length has twin towers that extend 70 meters above the road surface and are 1200 meters apart. The cables are parabolic in shape and are suspended from the tops of the towers. The cables touch the road surface at the center of the bridge. Find the height of the cables at a point 300 meters from the center. (Assume that the road is level.)
Answer:
17.5 m
Step-by-step explanation:
The height of a parabola above its vertex is proportional to the square of the distance from the vertex.
Cable heightThe towers are 1200 m apart, so each is 600 m from center. The location of interest is 300 m from center, so 1/2 the distance to a tower. Since the height is proportional to the square of the distance, the height half-way to the tower will be (1/2)² = 1/4 the height of the tower.
(1/2)²×(70 m) = 17.5 m
The height of the cable 300 m from center will be 17.5 meters.
Create a tree diagram for flipping an unfair coin two times. The probability of H is 2/3 and probability of T is 1/3. Write the probabilities on each branch.
The probabilities on each branch are shown in the tree diagram, and P(HT) = 2/9.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
The probability of H is 2/3 and the probability of T is 1/3.
P(HT) = P(H in the first trial)P(T in the second trial)
From the tree diagram:
P(HT) = (2/3)(1/3) = 2/9
Thus, the probabilities on each branch are shown in the tree diagram, and P(HT) = 2/9.

log 9-log 4÷log 3-log 2
Step-by-step explanation:
whoever created the original question and then probably the people copying it need to focus on writing these things correctly.
I assume this means
log(9) - log(4) ÷ log(3) - log(2)
or is anything combined in brackets ? like it could be e.g. log(4 ÷ log(3)). just as example.
and I guess we mean logarithm to the base of 10, right ?
anyway, if my assumptions are correct, then we only need to follow the regular priorities of mathematical operations :
1. brackets
2. exponents
3. multiplications and divisions
4. additions and subtractions
so, we need to start with the division in the middle, and then do the subtractions.
log(4) ÷ log(3) = 1.261859507...
log(9) - 1.261859507... = -0.307616998...
-0.307616998... - log(2) = -0.608646993...
or was the original question
(log(9) - log(4)) ÷ (log(3) - log(2))
?
that would be way more interesting.
we use the rules of logarithm :
e.g.
log(a×b) = log(a) + log(b)
log(a/b) = log(a) - log(b)
so, we have then
log(9/4) ÷ log(3/2)
and that is equal to
log(3/2 × 3/2) ÷ log(3/2)
(log(3/2) + log(3/2)) ÷ log(3/2) = 1 + 1 = 2
if that is the case, you really, REALLY need to pay more attention to brackets and other symbols in problem definitions.
