1 answer:

8 0

Given that a farmer has 13 cows if a bolt of lightning kills all but 5 of them, this means that the bolt of lightning killed all the cows except 5.

Therefore, the number of cows that survived is 5 cows.

On a coordinate plane, a triangle has points (negative 5, 1), (2, 1), (2, negative 1).

daser333 [38]

Answer:

Step-by-step explanation:

Given a triangle has points:

(-5,1),(2,1), (2,-1)

Let us label the points:

A(2,1),

B(-5,1) and

C(2,-1)

To find:

Distance between (−5, 1) and (2, −1) i.e. BC.

Horizontal leg AB and

Vertical leg, AC.

Solution:

Please refer to the attached diagram for the labeling of the points on xy coordinate plane.

We can simply use Distance formula here, to find the distance between two coordinates.

Distance formula :

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

For BC:

$x_2 = 2\\x_1 = -5\\y_2 = -1\\y_1 = 1$

$BC = \sqrt{(2--5)^2+(-1-1)^2} = \sqrt{63}$

Horizontal leg, AC:

$x_2 = -5\\x_1 = 2\\y_2 = 1\\y_1 = 1$

$AC = \sqrt{(2-(-5))^2+(1-1)^2} = 7$

Vertical Leg, AB:

$x_2 = 2\\x_1 = 2\\y_2 = -1\\y_1 = 1$

$AB = \sqrt{(2-2)^2+(-1-1)^2} = 2$

A function g(x) has x-intercepts at (StartFraction 1 Over 2 EndFraction, 0) and (6, 0). Which could be g(x)? g(x) = 2(x + 1)(x +

Tcecarenko [31]

Answer:

$g(x) = (x-6)(2x-1)$

Step-by-step explanation:

$g(x)$ intercepts the x-axis at these 2 points:

$(6,0) ;(1/2,0)$

⇒ 6 and 1/2 are roots ie; if you insert $x=6$ or $x=1/2$ into the equation of g(x) you will obtain a 0.

$g(6) = g(1/2) = 0$

now in order for 0 to appear we should have $x-6$

now in order for 0 to appear we should have $x-1/2$

but $x-1/2$ doesn't appear in any of these, but its multiple of 2 is there:

$2(x-1/2) = 2x-1$

Therefore the function;

$g(x) = (x-6)(2x-1)$
