Answer:

JK slope: -1/3
KL slope: 3
JL slope: -7
is
two of the slopes have a product of -1

Step-by-step explanation:

The slope formula is useful.

m = (y2 -y1)/(x2 -x1)

JK slope = (1 -2)/(3 -1) = -1/3

KL slope = (-5-1)/(1-3) = -6/-2 = 3

JL slope = (-5-2)/(1-0) = -7

We observe that slopes (-1/3) and (3) have a product of -1, so those line segments are perpendicular. The triangle is a right triangle.

Answer: Order will be F,D,C and Fourth Option is correct and x = 10

Step-by-step explanation:

Since we have given that

$\sqrt{6x+4}=8$

We first transpose the square root to the right , so it becomes square of 8,i.e.

$6x+4=8^2\\\\6x+4=64$

Now, transpose 4 to the right so it will get subtract from 64 i.e.

$6x=64-4\\\\6x=60$

Since 6 is multiplied to x on tranposing it will get divided by 60 i.e.

$x=\frac{60}{6}\\\\x=10$

Hence, on simplification, we get x=10.

Hence , the order is F,D,C.

A force of 84N is applied to an area of<br> 15cm". Work out the pressure in N/cm².<br> cm3)

Tcecarenko [31]

Answer: 5.6 N/cm^2

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

Work Shown:

Pressure = (Force)/(Area)

P = F/A

P = (84 N)/(15 cm^2)

P = (84/15) (N/cm^2)

P = 5.6 N/cm^2

For every square cm, 5.6 newtons of force is applied.

-------------

Extra info:

If you wanted to convert this to pascals, then you would need to convert 15 cm^2 to 0.0015 square meters. Then apply the formula above to get 56,000 pascals. 1 pascal is equivalent to 1 N/m^2.
