8b²+7b factorize it i want the explantion also pll help

tekilochka [14]

So you would but a b on the outside and on the inside, you would put 8b because b x 8b makes b^2. Then, you would put +7 for the 7b and then close the brackets and thats your answer b(8b+7)

PLEASE HELP! URGENT! <br> I don’t know how to graph this

jekas [21]

graph (-3, 5)

because you would set it equal to 0 so it would be x + 3 = 0 then subtract 3 on both sides to get x = -3

same thing with x-5

set it equal to 0 to get y - 5 = 0 then just add 5 to get y=5

The table shows the estimated number of bees, y, in a hive x days after a pesticide is released near the hive. Which function be

vladimir2022 [97]

Answer:

The exponential function best models the data for the given table.

Step-by-step explanation:

Given : The table showing the estimated number of bees, y, in a hive x days after a pesticide is released near the hive.

We have to find which function best models the data for the given table.

Consider the given data in the table.

We first plot the data using Expo- regression calculator (as shown in attachment)

Since, The the estimate number of bees deceases with increasing number of days ,thus the data represents an exponential decay over time.

Thus, The exponential function best models the data for the given table.

And the equation of model is given as $y=9958.3e^{-0.029x}$

Where y represents the estimate number of bees

and x represents the number of days.

Find the values of x and y that maximize the objective function P=3x+2y for the graph. What is the maximum value?

AURORKA [14]

Answer:

(9, 0)

Step-by-step explanation:

Maximum or minimum value occurs at the Corner. The points given are (0, 8), (5, 4) and (9, 0).

Substitute (0, 8) in the objective function.

We get P = 3(0) + 2(8) = 16

Now for (x , y) = (5, 4)

P = 3(5) + 2(4) = 15 + 8 = 23

At (9, 0) we get P = 3(9) + 2(0) = 27.

Clearly, we have the maximum value at (9, 0).

And the maximum value is 27.
