Answer:

The required product is $-48r^2-10r+3$

Step-by-step explanation:

Consider the provided expression.

$(6r-1)(-8r-3)$

Open the parentheses.

$6r\left(-8r\right)+6r\left(-3\right)+\left(-1\right)\left(-8r\right)+\left(-1\right)\left(-3\right)$

$-6\cdot \:8rr-6\cdot \:3r+1\cdot \:8r+1\cdot \:3$

$-48r^2-18r+8r+3$

Add the like terms.

$-48r^2-10r+3$

Hence, the required product is $-48r^2-10r+3$

What is the diameter of a sphere with volume of 7483

elena-14-01-66 [18.8K]

Answer:

The diameter of the sphere with the given volume is 24.268 units

Step-by-step explanation:

Volume of a sphere is given by the equation:

$V=4/3\pi r^3$

Plug in your volume and solve for r

$7483=4/3\pi r^3$

$7483(3/4)=\pi r^3$

$5612.25=\pi r^3$

$5612.25/\pi =r^3$

$1786.43=r^3$

$\sqrt[3]{1786.43}=r$

$r = 12.134$ units

$d = 2r$

$d = 2(12.134)$

$d = 24.268$ units

The answer is 48 because if a right angle is 90 degrees and angle one 42 then you do 90-42 and you get 48 for angle 2.
