Quadrant for for number 5

tresset_1 [31]3 years ago

4 0

5) Point D is located in Quadrant IV. Quadrant I is where x and y are both positive. Quadrant II is where x is negative and y is positive. Quadrant III is where both x and y are negative. Quadrant IV is where x is positive and y is negative.
6) Since we know that the x will be the same because it is a vertical line segment, we just have to find the absolute value of the difference between the y of the 2 points. Therefore, (3,-8) and (3,-4) is the correct answer.
7) Use the distance formula. √((y₂-y₁)²+(x₂-x₁)²). √((8-8)²+(7-(-5))²) = √(0+12²) = √12² = 12 units.

Find the maximum value of P=3x+2y subject to the following constraints:<br> Please help!!!

emmainna [20.7K]

Answer:

The maximum value of P is 18

Step-by-step explanation:

we have'the constraints

$5x+y\leq 16$ ---> constraint A

$2x+3y\leq 22$ ---> constraint B

$x\geq 0$ ---> constraint C

$y\geq 0$ ---> constraint D

using a graphing tool

The solution of the four constraints is the quadrilateral shaded area

The vertices of the quadrilateral area are

(0,0),(3.2,0),(2,6) and (0,7.33)

see the attached figure

To find out the maximum value of the objective function P, substitute the value of x and the value of y of each vertex in the objective function and then compare the results

For (0,0) ----> $P=3(0)+2(0)=0$

For (3.2,0) ----> $P=3(3.2)+2(0)=9.6$

For (2,6) ----> $P=3(2)+2(6)=18$

For (0,7.33) ----> $P=3(0)+2(7.33)=14.66$

therefore

The maximum value of P is 18

Multiply and simplify. (3x+5)(2x2−3x+2) Enter your answer, in standard form, in the box.

Sveta_85 [38]

Answer:

$6x^3+x^2-9x+10$

Step-by-step explanation:

We have the product, $(3x+5)(2x^{2}-3x+2)$ .

On simplifying the product, we get,

$(3x+5)(2x^{2}-3x+2)$

i.e. $6x^3-9x^2+6x+10x^2-15x+10$

i.e. $6x^3+x^2-9x+10$

Thus, the standard form of the product $(3x+5)(2x^{2}-3x+2)$ is $6x^3+x^2-9x+10$ .
