Answer:

The volume of the vase is 2122.64  cm^{3}

Step-by-step explanation:

Given data

Radius (R) = 6.5 cm

Height (H) = 16 cm

Volume of the vase is given by

V = \pi R^{2} H

Put all the values in above formula we get\

V = 3.14 × 6.5^{2} × 16

V = 2122.64 cm^{3}

Therefore the volume of the vase is 2122.64  cm^{3}

Factorize the following algebraic expression:
Hoochie [10]
X^2+16-38=0
find what 2 numbers multiply to get -38 and add to get 16
find factors of 38
2 times 19
there is no way to use common factor so use quadratic formula which is
x=\frac{ -b+\sqrt{b^2-4ac} }{2a} or x=\frac{ -b-\sqrt{b^2-4ac} }{2a}

ax^2+bx+c=0 subsitte
a=1
b=16
c=-38
subsitute
\frac{ -16+\sqrt{16^2-4(1)(-38)} }{2(1)}=\frac{ -16+\sqrt{256+152} }{2}= \frac{ -16+\sqrt{408} }{2}= \frac{ -16+2\sqrt{102} }{2}=-8+\sqrt{102}
so the answers for x are -8+\sqrt{102} and -8-\sqrt{102}  which are aprox -2.099504938362 and +18.099504938362
so it would be
(x-[-8+√102])(x+[8+√102])=0

Is the square root of 12 rational or irrational?
Andreyy89
<h3>Answer: Irrational</h3>

We cannot write sqrt(12) as a fraction of two whole numbers

Note how sqrt(12) = 3.464 and the decimal portion goes on forever without any known pattern (and it doesnt repeat either).

Compare this to something like sqrt(16) = 4 which can be written as a fraction 4/1, so sqrt(16) is rational

(X-3)(x+2)=0 find the zeros
Ivanshal [37]

Answer: Min = (0.5, −6.25)

Step-by-step explanation: Standard form:

x2 − x − 6 = 0

Factorization:

(x + 2)(x − 3) = 0

Solutions based on factorization:

x + 2 = 0   ⇒   x1 = −2

x − 3 = 0   ⇒   x2 = 3
