Answer:

Step-by-step explanation:

Find the prime factorization of 270

270 = 2 × 3 × 3 × 3 × 5

Find the prime factorization of 900

900 = 2 × 2 × 3 × 3 × 5 × 5

To find the gcf, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 3 × 3 × 5

GCF = 90

What is the approximate volume of the cone? Use 3.14 for π.

yawa3891 [41]

The formula for the volume of a cone is V= πr² (h/3).
V= 3.14 (12²) (8/3)
V= 3.14 (144) (2.6...)
V= 1205.76
V≈ 1206
So the answer is A.

Rotate the axes to eliminate the xy-term in the equation. Then write the equation in standard form.

kirill115 [55]

Answer:

$\dfrac{x'^2}{2}-\dfrac{y'^2}{2}=1$

Step-by-step explanation:

The rotation by angle $\theta$ formulas are

$\left\{\begin{array}{l}x=x'\cos \theta-y'\sin \theta\\y=x'\sin \theta+y' \cos \theta\end{array} \right.$

To eliminate the xy-term, we have to rotate by 45°, so

$\left\{\begin{array}{l}x=x'\cos 45^{\circ}-y'\sin 45^{\circ}\\y=x'\sin 45^{\circ} +y' \cos 45^{\circ}\end{array} \right.$

$\left\{\begin{array}{l}x=x'\dfrac{\sqrt{2}}{2}-y'\dfrac{\sqrt{2}}{2}\\y=x'\dfrac{\sqrt{2}}{2} +y' \dfrac{\sqrt{2}}{2}\end{array} \right.$

Substitute them into the equation $xy+1=0:$

$\left(x'\dfrac{\sqrt{2}}{2}-y'\dfrac{\sqrt{2}}{2}\right)\cdot \left(x'\dfrac{\sqrt{2}}{2}+y'\dfrac{\sqrt{2}}{2}\right)+1=0\\ \\\left(x'\dfrac{\sqrt{2}}{2}\right)^2 -\left(y'\dfrac{\sqrt{2}}{2}\right)^2+1=0\\ \\\dfrac{x'^2}{2}-\dfrac{y'^2}{2}=1$
