Kim is making a bouquet for her friend. She used x tulips and some daffodils in the bouquet. The number of daffodils is equal to
zzz [600]

Kim used 4 tulips in the bouquet.

Step-by-step explanation:

Tulips used = x

Daffodils used = x²

Total flowers in bouquet = 20

According to given statement;

x^2+x=20\\x^2+x-20=0

Factorizing the Eqn

x^2+5x-4x-20=0\\x(x+5)-4(x+5)=0\\(x+5)(x-4)=0

Either,

x+5=0        => x= -5

Or,

x-4=0        => x = 4

As the number of flowers cannot be negative, therefore,

x = 4 (Where x is the number of tulips used)

Kim used 4 tulips in the bouquet.

Use the method of this example to calculate F · dr, C where F(x, y) = 2xyi + (y2 − x2)j (x2 + y2)2 and C is any positively orien
Nina [5.8K]

Answer:

Using Green's theorem we have:

int F.dr = int int d/dx ((y^2-x^2)/(x^2+y^2)^2) - d/dy (2xy/(x^2+y^2)^2) =

(2x^3 - 6xy^2) / (x^2+y^2)^3 - (2x^3 - 6xy^2) / (x^2+y^2)^3 = 0

Therefore:

int F.dr = 0

If vertex U is located at (-4, 5) and vertex V is located at (-6, 2), then vertex U′ is located at
elixir [45]

The vertex U' is located at (-4, -5)

<h3>How to determine the location of U'?</h3>

The vertices are given as:

U = (-4, 5)

V = (-6, 2)

The rule of transformation is given as:

Reflection across the x-axis

This is represented as:

(x, y) => (x, -y)

So, we have:

U' = (-4, -5)

Hence, the vertex U' is located at (-4, -5)

3. Show that the expression 3b - 4 + 6(b-9) is equivalent to the expression 9 (b-6) -4. Show your work. ANSWER ASAP PLZZ
sattari [20]

EDITED:

so lets make the question more clear

lets make it like this, if were gonna make 10 = b vv (sorry I meant to say 10, but I said 6 ;-;

3(10) - 4 + 6(10-9) = 30 - 4 + 6 = 26 + 6 = 32

= THIS EQUALS 32

Now lets do 9(b-6) - 4 which will be turned into 9(10-6) - 4 = 36 - 4                          = THIS EQUALS 32

MY ANSWER IS YES (DONT ASK ME WHY IM WRITING IN CAPS (((: )
