I'm pretty sure the area of this triangle is 30 m squared. Can someone please tell me if I am right?

It is 30m.. Because you do 10x6=60 then divide it by 2 which is 20.. and hxb/2 is the formulas so.

You have a cat who has a mass of 10kg and is chasing a mouse with an acceleration of 10 m/s2. If it runs into a wall what force

V125BC [204]

Given:

mass of cat ( m ) = 10 kg

Acceleration ( a ) = 10 m/s²

To find out: 

If it runs into a wall what force will be exerted by the cat?

Formula used:

Force = mass × acceleration

Solution:

Force = mass × acceleration

Now, Putting these values of m and a in the above equation.

we get:

F = 10 × 10

= 100 N

Thus, the force will be exerted by the cat is 100 N.

Find all the zeros of the polynomial function p(x) = x3 – 5x2 + 33x – 29

hram777 [196]

Answer:

$\large \boxed{\sf \ \ x=1, \ \ x=2+5i, \ \ x=2-5i \ \ }$

Step-by-step explanation:

Hello,

I assume that we are working in $\mathbb{C}$ , otherwise there is only one zero which is 1. Please consider the following.

First of all, we can notice that 1 is a trivial solution as

$p(1) = 1^3-5\cdot 1^2 + 33\cdot 1-29=1-5+33-29=0$

It means that (x-1) is a factor of p(x) so we can find two real numbers, a and b, so that we can write the following.

$p(x)=(x-1)(x^2+ax+b)=x^3+ax^2+bx-x^2-ax-b=x^3+(a-1)x^2+(b-a)x-b$

Let's identify like terms as below.

a-1 = -5 <=> a = -5 + 1 = -4

b-a = 33

-b = -29 <=> b = 29

$\boxed{ \ p(x)=(x-1)(x^2-4x+29) \ }$

Now, we need to find the zeroes of the second factor, meaning finding x so that:

$x^2-4x+29=0 \ \text{ complete the square, 29 = 25 + 4} \\ \\ x^2-2\cdot 2 \cdot x+2^2+25=0 \\ \\ (x-2)^2=-25=(5i)^2 \ \text{ take the root } \\ \\x-2=\pm 5i \ \text{ add 2 } \\ \\ x = 2+5i \ \text{ or } \ x = 2-5i$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
