Write an equation passing through the point and parallel to the given line. (4,7);y=3x+4

Mathematics
1 answer:

3 0

Answer:

y = 3x - 5

Step-by-step explanation:

y = 3x + 4....the slope here is 3. A parallel line will have the same slope.

y = mx + b

slope(m) = 3

(4,7)...x = 4 and y = 7

now we sub and find b, the y int

7 = 4(3) + b

7 = 12 + b

7 - 12 = b

- 5 = b

so ur equation is : y = 3x - 5 <===

Suppose F⃗ (x,y)=4yi⃗ +2xyj⃗ . Use Green's Theorem to calculate the circulation of F⃗ around the perimeter of a circle C of radi
Juliette [100K]

Answer:

-9π

Step-by-step explanation:

∫c (4y dx + 2xy dy)

= ∫∫ [(∂/∂x)(2xy) - (∂/∂y)(4y)] dA, by Green's Theorem

= ∫∫ (2y - 4) dA

Now convert to polar coordinates:

∫(r = 0 to 3) ∫(θ = 0 to 2π) (2r sin θ - 4) * (r dθ dr) --- first integration

= ∫(r = 0 to 3) (-2r cos θ - 4θ) * r {for θ = 0 to 2π} dr

= ∫(r = 0 to 3) -2πr dr

= -πr² {for r = 0 to 3}

= -π(3²) - -π(0)²

= -9π

2x - 6 = 0 and 2y = 10. Find 3^x/3^y.
pshichka [43]

Answer:

\dfrac{1}{9}

Step-by-step explanation:

2x - 6 = 0

\implies 2x = 6

\implies x=3

2y = 10

\implies y=5

\dfrac{3^x}{3^y}=\dfrac{3^3}{3^5}=\dfrac{1}{3^2}=\dfrac{1}{9}

This is integrated math2, help plzzzz. i’m so lost idk what this is:/
Andrej [43]

I remember doing the last question.

If you recall, x = 29

Just plug 29 into x for each angle

A = 3(29) = 87

B = 2(29) + 1 = 59

C = 29 + 5 = 34
