To find one of the legs of a right triangle, you subtract one of the legs squared from the hypotenuse squared.

$7^{2} - 1^{2} = \sqrt{48}$

The length of the third side is $\sqrt{48}$

The area of the triangle formed by x− and y− intercepts of the parabola y=0.5(x−3)(x+k) is equal to 1.5 square units. Find all p

jeka57 [31]

Answer:

K = -1 or -2

Step-by-step explanation:

Given the equation of parabola is, y = 0.5(x-3)(x+k).

Finding y-intercept, put x=0 and solve for y :-

y = 0.5(0-3)(0+k)

y = 0.5(-3)(k)

y = -1.5k

Finding x-intercepts, put y=0 and solve for x :-

0 = 0.5(x-3)(x+k)

(x-3)(x+k) = 0

x = 3 OR x = -k

So, the coordinates of triangle ABC are:-

A(0, -1.5k), B(3, 0), and C(-k, 0)

Assuming origin O(0,0), find the area of triangle ABC:-

Area = (1/2) * BC * OA

Area = (1/2) * (k+3) * (1.5k)

But given the area is 1.5 square units.

So, (1/2) * (-k-3) * (1.5k) = 1.5

(1/2) * (-k-3) * (k) = 1

k(-k-3) = 2

-k² -3k -2 = 0

k² +3k +2 = 0

k² +2k +k +2 = 0

(k+2)(k+1) = 0

So, k = -1 or k = -2

Convert 3/8 to a decimal and percent but pls explain how you guys get 375 pls ;-;

natali 33 [55]

You just divide 3 by 8. when 3 is inside the "house" and 8 is outside, 8 doesn't go into 3 so move on and 8 goes into 30 3 times. and so forth. 30-24=6 bring down the 0. 8 goes into 60 7 times. the decimal is 0.375. the percent is 37.5%.

Which equation represents a line that passes through (–9, –3) and has a slope of –6?

IgorC [24]

Answer:

<h2>y + 3 = -6(x + 9) - point-slope form</h2><h2>y = -6x - 57 - slope-intercept form</h2>

Step-by-step explanation:

The point-slope form of an equation of a line:

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

<em>m</em><em> - slope</em>

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

========================================

We have the slope <em>m = -6</em> and the point (-9, -3).

Substitute:

$y-(-3)=-6(x-(-9))\\\\y+3=-6(x+9)$

Convert to the slope-intercept form (<em>y = mx + b</em>):

$y+3=-6(x+9)$ <em>use the distributive property</em>

$y+3=-6x-54$ <em>subtract 3 from both sides</em>

$y=-6x-57$
