Answer:
when k > 0 the traces parallel to the yz plane is an ellipse
The traces parallel to the xz plane are parabolas and they open in positive x- axis direction
The traces parallel to the xy plane are parabolas that open in the positive x-axis direction
Step-by-step explanation:
Given surface : [tex]x^2 = y^2 + 5z^2[/tex]
To determine the traces of the given equation we will have to make some assumptions and the assumption is
let x = k
[tex]k^2 = y^2 + 5z^2[/tex]
when k > 0 the traces parallel to the yz plane is an ellipse
let y = k
[tex]x^2 = k^2 + 5z^2[/tex]
The traces parallel to the xz plane are parabolas and they open in positive x- axis direction
Let z = k
[tex]x^2 = y^2 + 5k^2[/tex]
The traces parallel to the xy plane are parabolas that open in the positive x-axis direction
with the given traces The surface can be sketched

Answer:
3/2
Step-by-step explanation:
Given the equation 3/2(4x-2)-3x = 5-(x+2)
Open the parenthesis
3/2(4x) - 3/2(2) -3x = 5-x-2
6x-3-3x = 3-x
3x-3 = 3-x
Collect like terms
3x+x = 3+3
4x = 6
Divide both sides by
4x/4 = 6/4
x = 3/2
Hence the value of x is 3/2

1. To determine simple interest, we use the formula i=prt where i is the interest, p is the principal or initial amount, r is the interst rate and t is the time. Sometimes it can be tricky to know what value to use when calculating t. A. What would you plug into the simple interest formula for t if you were given a time of 3 years? B. What would you plug into the simple interest formula for t if you were given a time of 4 months? C. What would you plug into the simple interest formula for t if you were given a time of 45 days?
Step-by-step explanation:
To determine simple interest, we use the formula
[tex]I=Prt[/tex]
where I is the interest, p is the principal or initial amount, r is the interest rate is in the unit of years and t is the time in years
When the times is 3 years , then we plug in 3 for 't' directly
[tex]I=Pr(3)\\[/tex]
we know that 1 year = 12 months
Suppose, the time is given in months then we divide time 't' by 12
When the times is 4 months , then we plug in 4 for 't' and divide by 12
[tex]I=\frac{Pr(4)}{12}[/tex]
we know that 1 year = 365 days
Suppose, the time is given in days then we divide time 't' by 365
When the times is 45 days , then we plug in 45 for 't' and divide by 365
[tex]I=\frac{Pr(45)}{365}[/tex]

2. -6,-3
Step-by-step explanation:
One cold night the temperature was 0 degrees at 8 p.m. The temperature dropped at a constant rate from 8 p.m. to midnight. At midnight the temperature was −16.8 degrees. What was the temperature at 9 p.m.? Enter your answer into the box.
Answer:
- 4.2 degrees
Step-by-step explanation:
If the drop was from temp 0 at 8 pm to temp -16.8 at midnight (4 hours later)
then,the drop is given by the rate: -16.8/4 = - 4.2 degrees per hour
Therefore, at 9 pm the temperature was:
0 degrees - 4.2 degrees = - 4.2 degrees

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 90
miles per hour. The westbound train travels at 80 miles per hour. How long will it take for the two trains to be 408 miles
apart?
Do not do any rounding.
x = # of hours
80x + 90x = 408
Combine like terms.
170x = 408
Divide both sides by 408
x = 2.4 hours
It will take the trains 2.4 hours to be 408 miles apart.
The two trains will travel their 408-mile distance in around 2.4 hours.
To determine the time it will take for the two trains to be 408 miles apart, we can use the concept of relative motion.
Since the two trains are moving away from each other in opposite directions,
their speeds are added to calculate the rate at which the distance between them is increasing.
Let's consider the time it takes for the trains to be 408 miles apart:
Distance = Rate × Time
For the eastbound train:
Distance = 90 miles/hour × Time
For the westbound train:
Distance = 80 miles/hour × Time
Since the trains are moving away from each other, their distances traveled add up to the total distance between them:
90 miles/hour × Time + 80 miles/hour × Time = 408 miles
Combining like terms:
170 miles/hour × Time = 408 miles
To solve for Time, isolate it by dividing both sides of the equation by 170 miles/hour:
Time = 408 miles / 170 miles/hour
Now we can calculate the time:
Time = 2.4 hours
Therefore, it will take approximately 2.4 hours for the two trains to be 408 miles apart.

Emma buys produce for her dad’s French fry restaurant. She bought 55 bags of potatoes. There were 175 potatoes in each bag. How many potatoes did Emma buy? Susan solved the problem and said, “Emma purchased 1,750 potatoes for her dad’s restaurant.”
Answer:
9,625
Step-by-step explanation:
No. of potatoes present in each bag = 175
No. of bags of potatoes Emma brought = 55
So total no. of potatoes = 175 × 55
= 9,625

Rock climbing. I am out rock climbing, and the rock face has 4 easy, 7 challenging, and 3 extreme routes to get to the top. The routes are poorly marked, so I just choose one at random, with all routes equally likely. What is the probability that I do not choose an extreme route
Answer:
0.7857
Step-by-step explanation:
Given the following :
Number of Easy faces = 4
Number of challenging faces = 7
Number of extreme faces = 3
Total number of faces or route = (4 + 7 + 3) = 14
If one route is chosen at random, the probability of not choosing an extreme route will be :
Probability = (required outcome / Total possible outcomes)
P(not choosing an extreme route) = 1 - P(choosing an extreme route)
P(choosing an extreme route) = 3 / 14 = 0. 2143
Hence,
P(not choosing an extreme route) = 1 - 0.2143
= 0.7857

Terrence walks at a pace of 2 mi/h to the theater and watches a movie for 2 h and 15 min. He rides back home, taking the same route, on the bus that travels at a rate of 40 mi/h. The entire trip takes 3.5 h. How far along this route is Terrence’s house from the theater? Explain.
Answer:
2.2 miles
Step-by-step explanation:
3 hours and 30 minutes minus 2 hours and 15 minutes is 1 hour and 15 minutes. 2/40 gives you 0.05. 1.15 - 0.05 gives you 1 hour and 10 minutes and multiply that by 2 and it gives you 2.2 miles.
The distance between Terrence’s house from the theater will be 2.4 miles.
What is speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Distance is defined as the length between the two points.
Let us suppose the following parameters to get the distance.
D = distance of Terrence’s house from the theater
v₁ = speed at which Terrence walks from home to the theater = 2 mi/h
t₁ = time taken by Terrence to walk from home to the theater = D/v₁ = D/2
v₂ = speed at which Terrence returns back to home = 40 mi/h
t₂ = time taken by Terrence to return back to home = D/v₂ = D/40
t' = time spent in watching the movie = 2 h 15 min = 2.25 h
t = total time = 3.5 h
The distance will be calculated as given below:-
t = t₁ + t₂ + t'
3.5 = (D/2) + (D/40) + 2.25
D = 2.4 miles
