Okay so you are doing vectors... i obviously cannot give you an answer with numbers... but to find magnitude, do Pythagoreans theorem.

Determine the constant that should be added to the binomial so that it becomes a perfect square trinomial. Then write and factor

Nesterboy [21]

Answer:

$64, \ (x+8)^2$

Step-by-step explanation:

A perfect square trinomial is defined as an expression that is obtained from squaring a binomial equation. The perfect square trinomial is in the form of $ax^2+bx+c$ .

The given expression is :

$x^2+16x$

The co-efficient of the x-term in $x^2+16x$ is '16'.

So half of the term 16 ,

$\frac{16}{2} = 8$

and $(8)^2=64$

Now add 64 to the expression:

$x^2+16x+64$

Therefore, the perfect square trinomial is

$(x+8)^2=x^2+16x+64$

The figure is made up of a cylinder and a cone. What is the volume of the composite figure? Use 3.14 for Pi. Round to the neares

Delvig [45]

Answer:

The volume of figure is 310.86 cm³

Step-by-step explanation:

First, you have to calculate the volume of cone and cylinder seperately by applying the formulas :

Cone,

$v = \frac{1}{3} \times \pi \times {r}^{2} \times h$

$let \: \pi = 3.14 \\ let \: r = 3 \\ let \: h = 9$

$v = \frac{1}{3} \times 3.14 \times {3}^{2} \times 9$

$v = 84.78 \: {cm}^{3}$

Cylinder,

$v = \pi \times {r}^{2} \times h$

$let \: \pi = 3.14 \\ let \: r = 3 \\ let \: h = 8$

$v = 3.14 \times {3}^{2} \times 8$

$v = 226.08 \: {cm}^{3}$

Next, you have to add up both volumes as the figure are made from cone and cylinder :

$v = 84.78 + 226.08$

$v = 310.86 \: {cm}^{3}$
