Answer:

A) (15 x $3) + (10 x $2) + (12 x $1) = X

B) $77

Step-by-step explanation:

A) Each wrapping paper is 3 dollors, and they bought 15 (15 x 3)

Each greeting card is 2 dollors, and they bought 10 (10 x 2)

Each roll of ribbon is 1 dollors, and they bought 12 (12 x 1)

B) 15 times 3 is 45

10 times 2 is 20

12 x 1 is 12

45 + 20 + 12 = 77

find the particular solution to the exact differentiable equation dy/dx=(2e^x)-cosx passing through the point (0,3)

lozanna [386]

Answer:

y = 2eˣ - sin x + 1

Step-by-step explanation:

dy/dx = 2eˣ - cos x

(0, 3)

Integrate dy/dx to find the original function.

y = 2eˣ - sin x + C

Solve for C by substituting the point given.

3 = 2e⁰ - sin(0) + C
3 = 2 - 0 + C
1 = C

Now we can substitute C into the original function.

y = 2eˣ - sin x + 1

This is the particular, or explicit, solution to the differentiable equation.

school teacher and needs 22 pieces of wood, 3 over 8 ft long, for a class project. If he has a 9-ft board from which to cut the

tiny-mole [99]

Answer:

Yes, he will have enough 3 over 8 ft pieces for his class.

Step-by-step explanation:

Given:

Number of wood required = 22

Length of each wood, $l=\frac{3}{8}\textrm{ ft}$

Total length of the board, $L=9\textrm{ ft}$

Therefore, the number of woods that can be made using the given board is given as:

$\textrm{Number of woods made}=\frac{\textrm{Total length of board}}{\textrm{Length of each wood}}\\\textrm{Number of woods made}=\frac{L}{l}=\frac{9}{\frac{3}{8}}=9\times \frac{8}{3}=\frac{72}{3}=24$

So, he can make 24 woods of length $\frac{3}{8}\textrm{ ft}$ using the 9 ft board. But he has to make only 22 pieces.

Therefore, he has enough of the wood to make the required number of pieces.

What are the two answers someone help steps needed

velikii [3]

Answer:

p(4)= 8

p(-9)=-5

Step-by-step explanation:

it is stated in the third point that the remainder of the division is zero

then p(x)/(x+4)=1

p(x)=(x+4)

p(4)=(4+4)

p(-9)=(-9+4)
