The equation of the parabola that represents the given graph is y = 3x².
The correct option is B.
What is a parabola?A plane curve produced by a moving point such that its separation from a fixed point equals that of a fixed line is a parabola.
If the vertex of the parabola is at (0, 0), then the equation of the parabola has the form:
y = a x²
where "a" is a constant that determines the shape of the parabola. We need to find the value of "a" using the fact that the parabola passes through the point (1, 3).
Plugging in the coordinates of the passing point (1, 3), we get:
3 = a (1)²
3 = a
Therefore, the value of "a" is 5.
Hence, the equation of the parabola is:
y = 3x²

A Mars rover descended from the rim of a crater at a constant rate. After 2 days, the rover's elevation was 106 meters. After 6 days, its elevation was 48 meters. What elevation did the rover start at? ____meters Complete the equation that describes the relationship between the rover's elevation in meters, E, and the elapsed time in days, t. Write your answer using whole numbers or decimals rounded to the nearest tenth. E= ___ t+____
Answers
Answer:
135
E = - 14.5t + 135
Step-by-step explanation:
Given that, descent rate is constant ;
Elevation after 2 days = 106 m
Elevation after 6 days = 48 m
Let
Rate of elevation per day= x
Initial elevation = a
Hence,
a - 2x = 106 - - - (1)
a - 6x = 48 ___(2)
-2x + 6x = 106 - 48
4x = 58
x = 58/4
x = 14.5 meters per day
Hence, initial elevation :
a - 2(14.5) = 106
a - 29 = 106
a = 106 + 29
a = 135
Relationship between Rover's elevation, E and elapsed time, t
E = - 14.5t + 135
-14.5 = rate per day
The Harvey family stayed at a hotel for n nights. The cost was $80 per night plus a one-time fee of $20 because they brought their dog. Which expression represent the total cost of their hotel stay.
80n + 20n
80n + 20
80 + 20n
80 + 20 + n
Answers
Answer:
80n + 20
Step-by-step explanation:
20 stays the same because it's a one time fee. Then, for every night the Harvey family stays, it costs them eighty dollars. So, it's 80n + 20
Answer: 80n+20
Step-by-step explanation:
80 is the cost of nights you stayed but you don’t know the number of nights they dated so you place n next to 80 and they payed an additional 20 fee so you add that to 80n

Answer: C: cubic expression
Step-by-step explanation:
Classify the expression: 5x³ + 2x − 3
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
so
a) By the number of terms is a trinomial, because has three terms
b) By their degree The degree of the polynomial is found by looking at the term with the highest exponent on its variable
The highest exponent is 3 so this is a 3rd degree trinomial
therefore
Is a cubic expression

There are 40 working hours in a week and 52 weeks a year. How much does Nate need to make an hour to stay out of debt if it costs him $900 to live each month?
Answers
Answer: $5.19
Step-by-step explanation:
If there are 40 working hours in a week and 52 weeks in a year, 40 * 52 should be the amount of working hours in a year.
40 * 52 = 2080 working hours
Nate needs $900 to live each month and there are 12 months in a year, so $900 * 12 would equal how much he spends per year.
$900 * 12 = $10800
Divide $10800 by 2080 working hours to get how much he needs to make per working hour.
10800/2080 = approximately 5.19, rounded down from the nearest hundredth
He needs to make $5.19 per hour, so the answer is the last option.
