Hi!

Positive discriminants will give you two solutions.

Discriminants equal to zero will give you one solution.

Negative discriminants will give you no solutions.

In a graph, the number of solutions is where the graph crosses the x-axis.

In the first graph, we can see it intersects the graph at two points: (2, 0) and (6, 0). Since there are two solutions it is a positive discriminant.

In the second graph, we can see it intersects at one point: the origin, or (0, 0). Since there is one solution it is a discriminant equal to zero.

In the third graph, we can see it doesn't intersect; it is above the x-axis. Since there are no solutions it is a negative discriminant.

A rental car agency charges a flat fee of $139.00 plus $30.00 per day to rent a certain car. Another agency charges a fee of $13

Sveta_85 [38]

139 + 30d = 13 + 51d
139 - 13 = 51d - 30d
126 = 21d
126/21 = d
6 = d

now lets check..
139 + 30d = 139 + 30(6) = 319
13 + 51d = 13 + 51(6) = 319

so on day 6, they will both cost $ 319

Apopulation grows from its initial levelof 22,000 at a continuous growth rcte of 7.1% per year.a) Write a function to model the

solong [7]

Answer:

a) $P(t) = 22000(1.071)^{t}$

b) The population increases 7.1% each year.

Step-by-step explanation:

The continuous population growth model is given by:

$P(t) = P_{0}(1+r)^{t}$

In which $P(t)$ is the population after t years, $P_{0}$ is the initial population and r is the growth rate.

In this problem, we have that:

A population grows from its initial levelof 22,000 at a continuous growth rcte of 7.1% per year.

This means that $P_{0} = 22000, r = 0.071$

a) Write a function to model the population increase.

$P(t) = 22000(1 + 0.071)~{t}$

$P(t) = 22000(1.071)^{t}$

b) By what percent does the populaiion increase each year?

$r = 0.071$

So the population increases 7.1% each year.

Jimmy has to choose a coat and hat to wear outside. He has a choice of a red (R) or green (G) coat, and a choice of a blue (B) o

Andru [333]

Answer:

{GB,GY,RY,RB}

Step-by-step explanation:

Given : Jimmy has to choose a coat and hat to wear outside. He has a choice of a red (R) or green (G) coat, and a choice of a blue (B) or yellow (Y) hat.

To Find: What is the sample space for Jimmy's possible winter gear?

Solution :

Sample space : In probability theory, the sample space of an experiment or random trial is the set of all possible outcomes or results of that experiment.

To Form sample space

If he choose red coat(R) So, with that coat he can wear blue (B) or yellow (Y) hat.

So, sample space with red coat becomes {RY,RB}

Now If he choose green (G) coat So, with that coat he can wear blue (B) or yellow (Y) hat.

So, sample space with green coat becomes {GB,GY}

So, the sample space for the given situation is {GB,GY,RY,RB}

Hence the sample space for Jimmy's possible winter gear is {GB,GY,RY,RB}
