Which ratio is not equivalent to the other three? A 2 3 B 12 15 C 18 27 D 6 9

finlep [7]

Answer: B= 12 15

Step-by-step explanation:

The given ratios are

A) 2 3= 2: 3 already in its simplest form

B) 12 15 =12:15 Changing to its simplest form, we divide both by 3 giving us 4:5

C) 18 27 =18: 27 Changing to its simplest form, we divide both numbers by 9 giving us =2:3

D)6 9=6:9 Changing to its simplest form, we divide both by 3 giving us

2:3

Therefore the ratio not equivalent to other three is 12:15

Equation with a slope of -4 and goes through the point (-1,1)

spin [16.1K]

<h2>SOLVING</h2>

$\Large\maltese\underline{\textsf{A. What is Asked}}$

What's the equation with a slope of -4 that goes through (-1,1)? find it

$\Large\maltese\underline{\textsf{B. This problem has been solved!}}$

The equation used, here is $\bf{y-y1=m(x-x1)}$ .

$\bf{y-1=-4(x-(-1)}$ | simplify after putting in the information given

$\bf{y-1=-4(x+1)}$

$\rule{300}{1.7}$

$\bf{Result:}$

$\bf{=y-1=-4(x+1)}$

$\boxed{\bf{aesthetic\not101}}$

The base of a solid in the region bounded by the two parabolas y2 = 8x and x2 = 8y. Cross sections of the solid perpendicular to

Usimov [2.4K]

The two curves intersect at two points, (0, 0) and (8, 8):

$x^2=8y\implies y=\dfrac{x^2}8$

$y^2=\dfrac{x^4}{64}=8x\implies\dfrac{x^4}{64}-8x=0\implies\dfrac{x(x-8)(x^2+8x+64)}{64}=0$

$\implies x=0,x=8\implies y=0,y=8$

The area of a semicircle with diameter $d$ is $\dfrac{\pi d^2}8$ . The diameter of each cross-section is determined by the vertical distance between the two curves for any given value of $x$ between 0 and 8. Over this interval, $y^2=8x\implies y=\sqrt{8x}$ and $\sqrt{8x}>\dfrac{x^2}8$ , so the volume of this solid is given by the integral

$\displaystyle\frac\pi8\int_0^8\left(\sqrt{8x}-\dfrac{x^2}8\right)^2\,\mathrm dx=\frac{288\pi}{35}$
