I think it’s b but I may be wrong

leonid [27]

Answer:

D, not B

Step-by-step explanation:

So using Pythagorean Theorem:

$C^{2} =A^{2} +B^{2} \\x^{2} =144+265\\x^{2} =400\\x=20$

Yep, It's not B, But D.

Hope this helps!

5. An attacker swings a board with a mass of 2 kg toward a victim. The acceleration is 10 m/s2 when the board hits the victim. H

suter [353]

The force exerted on victim is 20 newton

Solution:

An attacker swings a board with a mass of 2 kg toward a victim

The acceleration is 10 $m/s^2$ when the board hits the victim

To find: Force exerted on victim

The force is given by formula:

$F = mass \times acceleration$

From given,

$mass = 2 \text{ kg }\\\\Acceleration = 10$ $m/s^2$

Substituting the values in formula,

$Force = 2 \times 10 = 20$

Thus force exerted on victim is 20 newton

Below are two different function, f(x) and g(x). what can be determined about their slopes?

babymother [125]

Answer:

F(x) has a larger slope.

Step-by-step explanation:

f(x) has a slope of 10 and g(x) has a slope of 9. The slope of f(x) can be found by dividing 800 by 80 (800 / 80 = 10). The slope of g(x) can be found by using the rate of change formula: y2 - y1 / x2 - x1. Choose two of the points from the chart. I'll use (2, -6) and (4, 12). Plug in the numbers so the equation would be 12-(-6) / 4-2. This simplifies to 18 / 2 which is 9.

X(x-4)+y(y-10)=-29 x;y=?

zaharov [31]

X sqrd-4x+y sqrd-10= -29
y sqrd-10y = -29-X sqrd + 4X
y(y-10) = -29-X sqrd +4X
y = - 29 -X sqrd +4X ÷( y- 10)
