What type of roots would you expect plants to have in the desert?

Answers

Answer:

Phreatophytes, like the mesquite tree, have adapted to desert conditions by developing extremely long root systems to draw water from deep underground near the water table.

Step-by-step explanation:

The mesquite's roots are considered the longest of any desert plant and have been recorded as long as 80 feet.

Answer:

Long roots for desert plants look similar to other roots, only more lengthy. The roots spread out from the base of the plant deep into the earth. Typically, the roots are larger than regular thread roots so that they absorb more water.

What is the multiplicative rate of change of the function?

1/3
2/3
2
9

Answers

Answer:

it is 2/3.

Step-by-step explanation:

please mark as brainliest .

2/3

As x increases by 1
Y decreases by a rate of 2/3.
6x2/3=4
4x2/3=8/3
And so on
To find 2/3, all you need to do is find how y is changing.
First of all, we know that y is decreasing as x increases so the rate is less than 1.
Take y2/y1 to get m or the rate
Ex. 4/6=2/3 which is less than 1!

A charity organization had to sell a few tickets to their fundraiser just to cover necessary production costs. After selling 101010 tickets, they were still at a net loss of \$800$800dollar sign, 800 (due to the production costs). They sold each ticket for \$70$70dollar sign, 70.

Answers

Answer:

Price of each ticket = $70

The revenue generated from sales of 10 tickets = 70 x 10 = $700

After selling the 10 tickets, organization was still at loss of $800. This means total product cost of tickets = $800 + $700 = $ 1500

Net Profit = Revenue - Cost

Revenue from n tickets will be = 70n

Cost = $1500

So, net profit as a function of number of tickets sold = P(n) = 70n - 1500

The table shows the relationship between X and Y.

X | Y

3 | 163.5

6 | 327

11 | 599.5

Which equation models this relationship?

A. y = 53x

B. y = 53.5x

C. y = 54x

D. y = 54.5x

PLEASE ANSWER I NEED THIS THE ANSWER NOW

Answers

Answer: C. y = 54x

Explanation:

Hope this helps you :)

An equation which models the relationship between X and Y is

y = 54.5x

The correct answer is option (D) y = 54.5x

What is equation?

"A mathematical statement which contains an equal symbol between two algebraic expressions that have the same value."

From given data we can observe that,

163.5/3 = 54.5 ...................(1)

327/6 = 54.5 ...................(2)

599.5/11 = 54.5 ...................(3)

From (1), (2) and (3),

y/x = 54.5

⇒ y = (54.5)x

Therefore, an equation which models the relationship between X and Y is y = 54.5x

The correct answer is option (D).
