we know that

The surface area of a cube is equal to

S=6*A

where

A is the area of one face of the cube

in this problem

A=8.5^{2}= 72.25\ in ^{2}

Find the surface area

S=6*72.25=433.5\ in ^{2}

therefore

<u>the answer is</u>

433.5\ in ^{2}  of wrapping paper is needed to cover the box completely

Determine whether the given differential equation is separable. StartFraction dy Over dx EndFraction plus 2 sine (x minus y )equ
Natalka [10]

Answer:

dy/dx+2sin(x-y)=0

so whether the given equation is separable or not

dy/dx= -2sin(x-y)

the given equation is not separable because the argument inside the function is dependent on both x and y

even though we use the formula to open the sin(A-B) we would still get the function dependent on both x and y and the equation would get complicated so instead use any other method.

What is the factored form of the function f(x)=x^3+8x^2+5x−50?
Inga [223]

Answer:

the factors of  f(x)=x^3+8x^2+5x-50 are (x-2)(x+5)(x+5)

Step-by-step explanation:

We need to factorise the function f(x)=x^3+8x^2+5x-50

If a number is a factor of this function than it must be completely divisible by last co-efficient. Our last co-efficient is -50

Checking few numbers:

f(1)=(1)^{3}+8(1)^2+5(1)-50\\f(1)=1+8+5-50\\f(1)=-32\\Now \ putting \ x= 2 \\f(2)=(2)^{3}+8(2)^2+5(2)-50\\f(2)=8+8(4)+10-50\\f(2)=8+32+10-50\\f(2)=0

So, f(2)=0 which means x-2 is a factor of the given function. Now we will perform long division of x^3+8x^2+5x-50 by (x-2) to find other factors

The long division is shown in figure attached.

After long division we get: x^2+10x+25

The equation x^2+10x+25 can be further simplified as: (x+5)(x+5) or (x+5)^2

So, the factors of  f(x)=x^3+8x^2+5x-50 are (x-2)(x+5)(x+5)

babymother [125]
P= 3000 (1.21)^t,  t= time in months

1 year = 12 months, and therefore, 1 month = 1/12 years

The equation showing yearly population growth changes to;

P=3000 (1.21)^t/12

The  correct answer is equation [1].
