<span>Sarah's conclusion is invalid, because she is testing two variables at once without a control value. In order for the experiment to be valid, Sarah should either apply the same soil to both areas (assuming they are, in fact, the same). Or, she should water both equally. At this time, we don't know if B grew "better" due to the brand or the amount of water received.</span>

A golfer takes two putts to get the ball into the hole. The first putt rolls the ball 10.3 feet in the northwest direction and t

creativ13 [48]

Let's put this on the usual Cartesian grid just so we can talk about it without drawing a picture. We'll use map conventions, right is east, up is north.

The ball starts at (0,0). 10.3 feet northwest means we have an isosceles right triangle whose diagonal is 10.3 feet. It's isosceles because northwest means equal parts north and west.

The sides of these triangles are in ratio $1:1:\sqrt{2}$ so the coordinates after the first putt are

$(- 10.3 / \sqrt{2}, 10.3 / \sqrt{2})$

The negative sign indicates west, which doesn't really matter for this problem. The distance from the origin to this point is 10.3 as required.

Now a second putt of 3.8 feet north puts us at

$(- 10.3 / \sqrt{2}, 10.3 / \sqrt{2} + 3.8)$

The squared distance to the origin is exactly

$d^2 = 10.3^2/2 + (10.3 / \sqrt{2} + 3.8)^2$

A little calculator work tells us

$d \approx 13.2621$

Third choice.

PLEAASE HELP I NEED UNGROUNDED

omeli [17]

Answer:

y=3x-2

Step-by-step explanation:

The formula for slope is y=mx=b

You can find the slope by finding two points that lie on the line (1,1) & (0,-2)

The formula for slope is $m=\frac{y_{2} -y_{1}}{ x_{2} -x_{1} }$

You plug the values in and you get $m=\frac{1-(-2)}{ 1 -0 }$

Simplify and you get 3

The slope is 3

The y-intercept (b) is -2

A line of a slope of 8 passes through the point (-6,4). What is its equation in point slope form?

kotykmax [81]

Answer:

$\huge\boxed{y-4=8(x+6)}$

Step-by-step explanation:

The equation of a line in the point-slope form:

$y-y_1=m(x-x_1)$

$m-slope\\\\(x_1;\ y_1)-point$

We have:

$m=8\\\\(-6;\ 4)\to x_1=-6;\ y_1=4$

Substitute:

$y-4=8(x-(-6))\\\\y-4=8(x+6)$

Match each quadratic equation with the best way to solve it. 1. 5x2 + 12x - 3 = 0 solve by square root method 2. x2 - 4x = 8 sol

Ksivusya [100]

<span>The best way to solve each equation is:

</span> 1) 5x2 + 12x - 3 = 0 -----> solve by quadratic formula
2) 4x2 - 25 = 0 -----------> solve by square root method
3) x2 - 5x + 6 = 0 --------> solve by factoring
4) x2 - 4x = 8 -------------> solve by completing the square
