No, the slope is positive.

The linear equation that shows how many packages of breadsticks Dirk bought as (1/4)b.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have Dirk who brought [b] breadsticks to a potluck. The breadsticks are packaged in bags of 4.

Assume that he bought [x] bags of breadsticks. Then, we can write the linear equation that shows how many packages of breadsticks Dirk bought as -

x = (1/4)b

Therefore, the linear equation that shows how many packages of breadsticks Dirk bought as (1/4)b.

Answer:

18

Step-by-step explanation:

24 x 20 = 480 (amount of seats on main floor)

786 - 480 = 306 (amount of seats needed on balcony)

306 ÷ 17 = 18 (amount of seats on each row of balcony)

Step-by-step explanation:

The main floor has 24*20 = 480 seats.

So you need 786- 480 = 306 more seats

There are 17 rows in the balcony and let's say there are x seats in each row. Since you need 323 seats, this means

19x = 323

x = 306/17

x = 18

So there must be 18 seats in each row up in the balcony.

Tom drives 243 miles in 3 hours.

What is speed?

So, to find how many miles Tom can drive in 3 hours:

Tom drives 81/2 miles every 1/30 hour.

81/2 miles = 40.5 miles

1/30 hours = 30 minutes

So, in 30 minutes Tom drives 40.5 miles.

Then, in 1 hour Tom will drive 40.5 + 40.5 = 81 miles.

Miles Tom will drive in 3 hours = 81 × 3 = 243 miles.

Number of groups of 3/4 are in 6 1/2 is, 26/3

We have to given that,

To find number of groups of 3/4 are in 6 1/2.

Let us assume that,

Number of groups of 3/4 are in 6 1/2 = x

Hence, We get;

x = (6 1/2) ÷ (3/4)

x = (13/2) × (4/3)

x = (13 × 4) / (2 × 3)

x = (13 × 2) / 3

x = 26/3

The concentration of a contaminant that enters a lake is a function of time and initially rises rather quickly. However, it is due to the lake's inherent mixing and self-cleansing activity.

Concentration in chemistry is calculated by dividing a constituent's abundance by the total volume of a mixture. The terms "concentration" can refer to any type of chemical mixture, but are most frequently used to describe the solutes and solvents in solutions. There are four different types of concentrations that can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration. There are different types of molar (quantity) concentrations, including normal concentration and osmotic concentration.

Concentration is frequently expressed qualitatively in everyday, non-technical language using words like "dilute" for solutions with a low concentration and "concentrated" for solutions with a high concentration.

If y increases quickly with x, the slope of the graph will be greater (i.e. will be steeper). The slope of the graph will be lower if y increases slowly with x. (i.e. will be less steeper). Straight lines result from constant slope in graphs. 1. Less investment results in a significant boost in production at first. Consequently, graph

Actors that can be manipulated by humans or artificial intelligence (AI) all descend from the Pawn class. A player or AI entity's physical representation in the world is called a "Pawn." This means that the player's or AI entity's physical interactions with the outside environment, such as collisions and other physical interactions, are likewise controlled by the Pawn. This can be perplexing in some situations because some game types might not have an obvious player mesh or avatar. Regardless, the Pawn continues to reflect a player or other entity's actual position, rotation, etc. within the game. A unique class of Pawn that can move around is called a Character.

The default relationship between Controllers and Pawns is one to one, which means that each Controller can only have one Pawn under their control at any given moment. Additionally, a Controller does not necessarily hold a Pawn that spawns while a game is being played.

The average rate of change of the function over the interval is 8(b + 1)

The given parameters are

Function: f(x) = 8x^2 - 6

Interval: [1, b]

Calculate f(1) and f(b) using the function definition

So, we have

f(1) = 8(1)^2 - 6 = 2

f(b) = 8(b)^2 - 6 = 8b^2 - 6

The average rate of change of the function over the interval is then calculated as

Rate = [f(b) - f(1)]/[b - 1]

This gives

Rate = [8b^2 - 6 - 2]/[b - 1]

Evaluate

Rate = [8b^2 - 8]/[b - 1]

Factorize the numerator

Rate = [8(b + 1)(b - 1)]/[b - 1]

Divide through by b - 1

Rate = 8(b + 1)

Hence, the average rate of change of the function over the interval is 8(b + 1)

Given that the length of a bacterial cell is about 5.36 x 10⁻⁴ m, and the length of an amoeba cell is about 6.2 x 10⁻⁴ m.

Ratio of the size of the cell is

B/A = 5.36 x 10⁻⁴/6.2 x 10⁻⁴

B/A = 5.36/6.2
