Step-by-step explanation:
"y is inversely proportional to the cube of x" means ...
y = k/x³
The value of k can be found from ...
k = x³y
The second table entry lends itself to easy computation of k:
k = 1³·8 = 8
Then the third table entry is ...

A student takes the same street from his home to the university every day. There are 3 streetlights along the way, and he has noticed the following Markov dependence. If he sees a green light at an intersection, then 77% of time the next light is also green. However, if he sees a red light, then 77% of time the next light is also red. (Assume the chance of him seeing a yellow light is zero.) If the first light is green, what is the probability that the third light is red
Answer:
0.3542 = 35.42% probability that the third light is red
Step-by-step explanation:
For each light:
If it is green, 77% probability that the next is green.
If it is red, 77% probability that the next is red.
If the first light is green, what is the probability that the third light is red?
These following outcomes are desired, for the second and third lights:
G - R(0.77, then 1 - 0.77 = 0.23 probability)
R - R(0.23, then 0.77 probability).
So the desired probability is:
[tex]p = 0.77*0.23 + 0.23*0.77 = 0.3542[/tex]
0.3542 = 35.42% probability that the third light is red

If a varies jointly as b and c, find a when b = 4 and c = -3.
a = -96 when b = 3 and c = -8
a=
Answer:
a=4bc
a=4(4)(-3)=-48
a= - 48 when b equals to 3 is equals to - 8
The required answer by direct variation a is equal to 96. In other words, when b = 4 and c = -3, the value of a is 96.
When a variable varies jointly as two other variables, it means that the relationship between the variables can be expressed using direct variation. In this case, we have that "a varies jointly as b and c."
To find the value of a when b = 4 and c = -3, we can set up the proportion based on the direct variation relationship:
a/bc = k
where k is the constant of variation.
Substituting the given values:
a/(4)(-3) = k
Simplifying, we have:
a/-12 = k
Now, we can find the value of a when b = 4 and c = -3 by substituting these values into the equation and solving for a:
a/(-12) = k
a/(-12) = -96/-12 (since k = -96 when b = 3 and c = -8)
a = 96
Therefore, the required answer by direct variation a is equal to 96. In other words, when b = 4 and c = -3, the value of a is 96.

Use the given information to write the standard form equation of a circle:
a) x²+y²+10x+14y+70=0 translated 1 unit to the right and 2 units down.
Answer:
The formula for the equation of a circle is (x – h) 2 + (y – k) 2 = r 2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
Step-by-step explanation:
A small airplane used 7 1/3 gallons of fuel to fly a 3 hour trip. How many gallons were used each hour? Each day?
Answer:
approximately 2.44 per hour, and 175.92 per day
Step-by-step explanation:
We can use 7.33 as 7 and 1/3rd.
If you take 7.33 and divide by 3, representing 3 hours, it equals 2.44333333.
If you round this to the nearest hundredth, you get the answer 2.44
For each day, you take the original number, 7.33, and multiply it by 8 to assume that the trip was 24 hours.
7.33 * 24 = 175.92.

The height of a cone is two times its base diameter. What is the volume of the cone in terms of its base radius ?
Step-by-step explanation:
Cone Volume = 1/3 ×( π r² h) h = 2 × diameter = 2 × 2 × r
Cone Volume = 1/3 ×( π r² h) h = 2 × diameter diameter = 2r
= 2 × (2 × r)
= 4r
Cone Volume = 1/3 ×( π r² 4r)
= (4 π r³ / 3)

2 to the 4th power divided by [(3.35 x 0.8) + 5.32]
Answer:
2Step-by-step explanation:
First we need to rewrite this part word problem completely into numbers
2⁴ ÷ [(3.35 × 0.8) + 5.32]
Now we must solve. Remember to do parenthesis first.
3.35 × 0.8 = 2.68
2.68 + 5.32 = 8
Now we need to find the value of 2⁴
2⁴ = 2 × 2 × 2 × 2 = 16
Finally we need to divide 16 by 8
16 ÷ 8 = 2
So our final answer is 2

If p is inversely proportional to the square of q, and p is 25 when q is 3, determine p
when q is equal to 5.
Answer:
p = 9 when q = 5.
Step-by-step explanation:
p is inversely proportional to the square of q
This means that:
[tex]p = \frac{k}{q^2}[/tex]
In which k is a constant multiplier.
p is 25 when q is 3
We use this to find k.
[tex]p = \frac{k}{q^2}[/tex]
[tex]25 = \frac{k}{3^2}[/tex]
[tex]k = 25*9 = 225[/tex]
So
[tex]p = \frac{225}{q^2}[/tex]
Determine p when q is equal to 5.
[tex]p = \frac{225}{q^2} = \frac{225}{5^2} = 9[/tex]
p = 9 when q = 5.

The pupils in my class work very quickly. Jasleen answers four questions every
30
seconds and Ella answers five questions every
40
seconds.
Last week, Jasleen took exactly
1
hour to answer a large set of questions.
How many minutes more than Jasleen did Ella take to answer the same set of questions?
Answer:
4 mins more would be taken by Ellina
Step-by-step explanation:
Given that
Jasleen answers 4 questions every 30 seconds
And, Ella answers 5 questions every 40 seconds
And, last week Jasleen took exactly 1 hour for answering a large set of questions
We need to find out the number of more minutes taken by Ella
As Jasleen answers four questions every 30 seconds
So, Jasleen answers 8 questions for every 1 minutes
Now
Jasleen answers time taken
= 60 × 8
= 480 questions for every 60 minutes or 1hr
On the other hand
Ella answers five questions every 40 seconds.
So, 1 questions in 8 sec
Now for 480 Questions , it would take
= 480 × 8 secs
= 480 × 8 ÷ 60 min
= 8 × 8
= 64 mins
Hence 4 mins more would be taken by Ellina

Find the volume of the figure below. Use 3.14 for π, and round your final answer to the nearest tenth.
Answer:
79.25 mm³
Step-by-step explanation:
The figure can be decomposed into 2 different half cylinders and a rectangular prism
Volume of the figure = volume of the smaller half cylinder + larger half cylinder + rectangular prism
✔️Volume of smaller half cylinder = ½(πr²h)
r = ½(2) = 1 mm
h = 5 mm
π = 3.14
Volume of smaller half cylinder = ½(3.14*1²*5)
= 7.85 mm³
✔️Volume of larger half cylinder = ½(πr²h)
r = ½(4) = 2 mm
h = 5 mm
π = 3.14
Volume of smaller half cylinder = ½(3.14*2²*5)
= 31.4 mm³
✔️Volume of rectangular prism = L*W*H
L = 5 mm
W = 4 mm
H = 2 mm
Volume = 5*4*2 = 40 mm³
✅Volume of the figure = 7.85 + 31.4 + 40
= 79.25 mm³
