NO LINKS

Question:

What is the area of the

rectangle?

(rectangle is 5/7 ft wide and 3 1/2 ft long)

Enter your answer as a mixed number in simplest form in the box.

Answer:

2 1/5

Step-by-step explanation:

Because we are finding the area we are multiplying and the formal is L x W = Area so the Length is 3 1/2 and the width is 5/7 so we multiply them and we get: 2.5

3 1/2 x 5/7 = 2.5 let make it a mixed number 5/2 let simplify it now 5 divided by 2 = 2 1/5

is the answer

What is the solution to the inequality below?

dimaraw [331]

12 + x ≥ 3 (x - 6)
or, 12 + x ≥ 3x - 18
or, 12 + 18 ≥ 3x - x
or, 30 ≥ 2x
or, 30/2 ≥ x
or, 15 ≥ x
or, x ≤ 15

Answer:

x ≤ 15

Hope you could get an idea from here.

Given the following constants for a standard form quadratic equation, determine the nature of its roots.

Firdavs [7]

Given that

a=3

b=3

c=2

The number and kind of roots depend on the Discriminant of the equation .

Formula for the Discriminant ,D is given by this

$D = b^{2} -4ac$

So using the formula we get that

$D = 3^{2} -4*3*2\\D=9-24\\D= -15$

Concept is that if the Discriminant is negative then no real solution is possible ,

here using the Discriminant formula we have got the Discriminat value as -15 which is a negative number so we say there is no real solution for the given information .

Hence C is the correct option .

Solve the following differential equation: (2x+5y)dx+(5x−4y)dy=0 *Hint: they are exact C=.

Tpy6a [65]

Answer with Step-by-step explanation:

The given differential equation is

$(2x+5y)dx+(5x-4y)dy=0$

Now the above differential equation can be re-written as

$P(x,y)dx+Q(x,y)dy=0$

Checking for exactness we should have

$\frac{\partial P}{\partial y}=\frac{\partial Q}{\partial x}$

$\frac{\partial P}{\partial y}=\frac{\partial (2x+5y)}{\partial y}=5$

$\frac{\partial Q}{\partial x}=\frac{\partial (5x-4y)}{\partial x}=5$

As we see that the 2 values are equal thus we conclude that the given differential equation is exact

The solution of exact differential equation is given by

$u(x,y)=\int P(x,y)dx+\phi(y)\\\\u(x,y)=\int (2x+5y)dx+\phi (y)\\\\u(x,y)=x^2+5xy+\phi (y)$

The value of $\phi (y)$ can be obtained by differentiating u(x,y) partially with respect to 'y' and equating the result with P(x,y)

$\frac{\partial u}{\partial y}=\frac{\partial (x^2+5xy+\phi (y)))}{\partial y}=Q(x,y))\\\\5y+\phi '(y)=(5x-4y)\\\\\phi '(y)=5x-9y\\\\\int\phi '(y)\partial y=\int (5x-9y)\partial y\\\\\phi (y)=5xy-\frac{9y^2}{2}\\\\\therefore u(x,y)=x^2+10xy-\frac{9y^2}{2}+c$
