Inga [223]

Answer:

y = -3x + 1

Step-by-step explanation:

slope = -3

y = mx + b

7 = -3(-2) + b

7 = 6 + b

1 = b

y = -3x + 1

What is the volume of a sphere with a radius of 1/4

MA_775_DIABLO [31]

What is the volume of a sphere with a radius of 1/4

$\bold{volume \: of \: cube \: = \: \frac{1}{3} \times \pi \times {r}^{3} }$

putting given value in formula

$\implies \: \: \frac{1}{3} \times \frac{22}{7} \times ( \frac{1}{4} ) {}^{3}$

$\implies \: \: \frac{1}{3} \times \frac{22}{7} \times \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4}$

$\implies \: \: \frac{22}{21} \times \frac{1}{64} \\ \\ \implies \: \: \frac{22}{1344}$

$volume \: = \: \frac{22}{1344}$

same can be done while talin pi as 3.14 ..... and you will be able tp get answer as decimal , so lets try that : -

$\implies \: \: \frac{1}{3} \times 3.14 \times ( \frac{1}{4} ) {}^{3} \\ \\ \implies \: \frac{1}{3} \times \frac{1}{64} \times 3.14$

$\implies \: \: \frac{1}{192} \times 3.14$

An archaeologist at a dig sets up a coordinate system using string. Two similar artifacts are found one at position (1, 4) and t

myrzilka [38]

Given:

Positions of two artifacts are at points (1, 4) and (5, 2).

To find:

The distance between these two artifacts.

Solution:

Distance formula: The distance between two points is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Using distance formula, the distance between two points (1, 4) and (5, 2) is

$d=\sqrt{(5-1)^2+(2-4)^2}$

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

$d=\sqrt{16+4}$

$d=\sqrt{20}$

$d=4.4721359$

Round to the nearest tenth of a unit.

$d\approx 4.5$

Therefore, the distance between two artifacts is 4.5 units.
