$976 and 25% intrest for 4 years
tatuchka [14]

Answer:

<h3>1952.00</h3><h3>I=976</h3>

Step-by-step explanation:

<u><em>SIMPLE INTEREST FORMULA:</em></u>

I- Interest

P- Principal

R- Rate

T-Time

P=976

R=25

T=4 years

976*25%4

25%=0.25

Solve.

Multiply.

976*0.25*4

976*0.25*4=976

I=976

976 and $1952.00, which is our answer.

Let C be the positively oriented square with vertices (0,0), (1,0), (1,1), (0,1). Use Green's Theorem to evaluate the line integ
liq [111]

Answer:

1/2

Step-by-step explanation:

The interior of the square is the region D = { (x,y) : 0 ≤ x,y ≤1 }. We call L(x,y) = 7y²x, M(x,y) = 8x²y. Since C is positively oriented, Green Theorem states that

\int\limits_C {L(x,y)} \, dx + {M(x,y)} \, dy = \int\limits^1_0\int\limits^1_0 {(Mx - Ly)} \, dxdy

Lets calculate the partial derivates of M and L, Mx and Ly. They can be computed by taking the derivate of the respective value, treating the other variable as a constant.

  • Mx(x,y) = d/dx 8x²y = 16xy
  • Ly(x,y) = d/dy 7y²x = 14xy

Thus, Mx(x,y) - Ly(x,y) = 2xy, and therefore, the line ntegral is equal to the double integral

\int\limits^1_0\int\limits^1_0 {2xy} \, dxdy

We can compute the double integral by applying the Barrow's Rule, a primitive of 2xy under the variable x is x²y, thus the double integral can be computed as follows

\int\limits^1_0\int\limits^1_0 {2xy} \, dxdy = \int\limits^1_0 {x^2y} |^1_0 \,dy = \int\limits^1_0 {y} \, dy = \frac{y^2}{2} \, |^1_0 = 1/2

We conclude that the line integral is 1/2

PLEASE HELP ME 3X+1/14=2X/8 WHAT IS  X? EXPLAIN HOW YOU GOT THE ANSWER
balandron [24]
Cross-multiply so that 8(3x + 1) = 14(2x)

Distribute the 8 and 14 into the parentheses:
24x + 8 = 28x

Subtract 24x from both sides:
8 = 4x

Divide both sides by 4:
x = 2
