Answer:

4 and 6.

Step-by-step explanation:

There are 4 different grades represented, so for the first question, there are 4 ways that the students can sit if they must sit together by grade.

For the second question, there are 3 grades other than senior level, so it starts with 3 ways that the students can be seated. 3 ways x 2 students per way = 6 ways

When Eric multiplied two binomials together, his result was a trinomial. An example is

leva [86]

Answer:

(x + 4)(x - 4)

Step-by-step explanation:

There are actually quite a lot of pairs of binomials the disproves Eric's conclusion, but they all model after the same special product: a^2 - b^2.

The special product a^2 - b^2 can be factored into (a + b)(a - b) and for all real a and b, it will come out as a binomial.

Here is an example:

(x + 4)(x - 4)

We can use the distributive property to get:

x^2 - 4x + 4x - 16

which is the same as

x^2 - 16

This would disprove Eric's conclusion.

If represents the number of bacteria in a culture at time t, how many will there be at time

Crazy boy [7]

Answer:

Population of bacteria at time $t = 6$ is $2441$

Step-by-step explanation:

The complete question is

If $y = 10 (2.5)^t$ represents the number of bacteria in a culture at time t, how many will there be at time $t = 6$

Solution

Given

The population of bacteria after time t is equal to $y = 10 (2.5)^t$

Population when at time $t = 6$

We will substitute the value of time in above equation.

$y = 10 (2.5)^6\\y = 10 *244.14\\y = 2441.4 = 2441$
