PLEASE HELP!! WILL GIVE BRAINLIST!!!! Is the binomial a factor of the polynomial function? f(x)=x^3+4x^2−25x−100 Select Yes or N
pochemuha

Answer:

See below

Step-by-step explanation:

y = x^2 (x + 4) - 25(x + 4)

y = (x + 4)(x^2 - 25)

y = (x + 4)(x + 5)(x - 5)

  • x - 5 is a yes
  • x + 2 is a no
  • x - 4 is a no

The coordinates of the verticies of triangle ABC are A(2,5), B(6,-1), and C(-4,-2). Fint the perimeter of triangle ABC, to the n
deff fn [24]

Answer:

24.4 Units

Step-by-step explanation:

For this, we will use the distance formula to find the distance between each vertex

\sqrt({x_{1}-x_{2} })^{2} +(y_{1} -y_{2})^{2}

So we do this for each side of the triangle to get AB = \sqrt{52}, BC = \sqrt{109}, and AC = \sqrt{45}

We add these all up to get 24.4 (rounded)

1.2, 3, 7.5, 18.75, ...<br><br> Which formula can be used to describe the sequence?
Nady [450]

Answer:

The formula is:

a_n=1.2(\frac{5}{2})^{n-1}

Step-by-step explanation:

The geometric sequences are those in which the division between the terms a_{n + 1} and a_n of the sequence are equal to a constant common reason called "r"

The geometrics secencias have the following form:

a_n=a_1(r)^{n-1}

Where a_1 is the first term of the sequence

In this sequence we have the following terms

1.2, 3, 7.5, 18.75

Then notice that:

\frac{3}{1.2}=\frac{5}{2}\\\\\frac{7.5}{3}=\frac{5}{2}\\\\\frac{18.75}{7.5}=\frac{5}{2}

Then:

r=\frac{5}{2}  and a_1=1.2

Finally the formula is:

a_n=1.2(\frac{5}{2})^{n-1}
