when a spherical balloon filled with air diameter of 6 inches what's the volume of balloon in cubic inches

Cerrena [4.2K]

Volume of sphere: V(s) = 4/3*pi*R^3 = (4/3)*pi*(D/2)^3 = (1/6) * pi * D^3

Volume of cube: V(c) = s^3

Volume of them is the same, I'm assuming you actually want to know the length of the cubic vertice

So s^3 = (1/6)*pi*D^3 -> s = (1/6 * pi)^1/3 * 6 = (36pi)^1/3

Find the magnitude of a vector with initial point A(3, 4, 10) and terminal point B(8, 4, –2).

Fantom [35]

Answer:

B

Step-by-step explanation:

Use the distance formula in 3 dimensions

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2+(z_{2}-z_{1})^2 }$

with (x₁, y₁, z₁ ) = (3, 4, 10) and (x₂, y₂, z₂ ) = (8, 4, - 2)

d = $\sqrt{(8-3)^2+(4-4)^2+(-2-10)^2}$

= $\sqrt{5^2+0^2+(-12)^2}$

= $\sqrt{25+144}$

= $\sqrt{169}$

= 13 → B

The area of a rectangular deck can be modeled by f(x) = 2x3 + 30x2 – 6x – 90. If x + 15 represents the width, which expression r

zhannawk [14.2K]

Divide f(x) by x + 15

this comes to 2x^2 - 6 which represents the length

Find the difference of the following polynomials:<br> (-2r4 + 3r3 - 10) and (4r4 - p3 + 2r2 + 7).

Vilka [71]

$-6 r^{4}+4 r^{3}-2 r^{2}-17$ is the difference between $-2 r^{4}+3 r^{3}-20 \text { and } 4 r^{4}-p^{3}+2 r^{2}+7$

Step-by-step explanation:

Given equations,

$-2 r^{4}+3 r^{3}-20 \text { and } 4 r^{4}-p^{3}+2 r^{2}+7$

Difference of the polynomial is written as

$=-2 r^{4}+3 r^{3}-20-\left(4 r^{4}-p^{3}+2 r^{2}+7\right)$

Open the brackets and multiply with -1 the whole expression $\left(4 r^{4}-p^{3}+2 r^{2}+7\right)$ becomes

$=-2 r^{4}+3 r^{3}-20-4 r^{4}+p^{3}-2 r^{2}-7$

$=-6 r^{4}+4 r^{3}-2 r^{2}-17$

This is the difference of given two polynomials is $-6 r^{4}+4 r^{3}-2 r^{2}-17$ .
