A) Write 2 expressions for the area of the shaded region.

Please help |3r -6| =21

julsineya [31]

3r-6=-21

3r-6+6=-21+6 (Add 6 to both sides...)

3r=-15

r=-5

3r-6=21

3r-6+6=21+6 (Add 6 to both sides...)

3r=27

r=9

r=-5 or r=9

The profit from a business is

GuDViN [60]

First of all we will understand the question!!

The question is saying that you are given a function and you have to find the value of x which will give the maximum profit... Lets solve it by finding the extrema using the vertex

 $\rm \: p(x) = - 5 {x}^{2} + 30x + 8$ 

Identify the coefficients a and b of the quadratic function

 $\rm \: p(x) = { - 5x}^{2} + 30x + 8 \\ \rm \: a = - 5 \: and \: b \: = 30$ 

Since a<0, the function has the maximum value at x, calculated by substituting a and b into x=-b/2a

$\rm \: x = \frac{30}{ 2 \times (- 5)}$

Solve the equation for x

$\rm \: x = 3$

The maximum of the quadratic function is at x=3

Evaluate 2r²+3s³-r²+4+²-r²

Vilka [71]

$2r^2 + 3s^3-r^2+4^2+-r^2 \\ \\ 2r^2 + 3s^3 - r^2 + 16 + -r^2 \\ \\ 2r^2 + 3s^3 = r^2 16 - r^2 \\ \\ (2r^2 - r^2-r^2) + 3s^3+ 16 \\ \\ 3s^3 + 16 \\ \\ Answer: 3s^3 + 16$

do you think space agencies should continue to explore Mars for evidence of past habitability? Why or why not? Explain your thin

Dima020 [189]

Since the earth is exceeding its carrying capacity, scientists should continue to seek for biosignatures in Mars that could confirm its possible habitability.

<h3>Should scientists continue to explore Mars?</h3>

The solar system is composed of the sun and the planets. The sun is the focus and the planets orbit the sun in concentric circles. We know that this is the heliocentric model of the solar system.

Given the fact that the population density on earth has begun to exceed its carrying capacity and many environmental challenges are beginning to emerge, It is only right that scientists should continue to seek for biosignatures in Mars that could confirm its possible habitability.
