Answer:

Step-by-step explanation:

I believe that if -3 =x then

-(-3)6 - (3)3 +2 =0 or 18-9+2=0

which is clearly not correct.

Answer:

Step-by-step explanation:

The exponents are too far apart for a +2 to make a difference.

Answer:

They wanted things done a certain way.

Step-by-step explanation:

When you imagine something in your head you think of it and when it actually happens you want it to be just like you imagined it. In order to have it just the way that you want it you have to have rules so that it would stay just as you wanted it. If something were messed up or done wrong while farming that could cause a time where they go with out and there could be hard time where some people go without food if even one little thing is done wrong.

Write the equation of the circle centered at (-4,3) with a radius of 7

Harrizon [31]

Answer:

(x + 4)² + (y - 3)² = 49

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (- 4, 3) and r = 7 , thus

(x - (- 4))² + (y - 3)² = 7² , that is

(x + 4)² + (y - 3)² = 49

leonard is flying kite he is holding the end of the string at distance of 1.2 m above the ground. if the string is 15 m how long

larisa86 [58]

Answer:

The kite is 10.8 m above the ground.

Step-by-step explanation:

Here we can make a triangle rectangle like the one shown in the graph below, where we want to find the value of the cathetus X, and that plus 1.2m will be the distance between the kite and the ground.

Notice that X is the opposite cathetus to the 40° angle, then:

We can use the relation:

Sin(θ) = (opposite cathetus)/(hypotenuse)

where, in our case, we have:

θ = 40°

hypotenuse = 15m

opposite cathetus = X

Replacing these in the equation, we get:

Sin(40°) = X/15m

Now we can solve this for X.

Sin(40°)*15m = X = 9.6m

And the actual height of the kite is X + 1.2m

Then:

H = 9.6m + 1.2m = 10.8m

The kite is 10.8 m above the ground.
