Typically, you plot independent (x) vs dependent (y). Also, we list the variables on a table as x on top and y below. In this situation the miles travelled would be the variable the researcher controls (the independent variable) and number the of gallons used would be what was measured (the dependent variable).

7- square root of 3i

r-ruslan [8.4K]

Step-by-step explanation:

Any complex number is of the form: $a + bi$ where a is real part and B is imaginary part.

Therefore, in given complex number: $7- \sqrt {3}i$

7 is real part.

$\sqrt {3}$ is imaginary part.

Hence, first two options are correct.

Last two options are incorrect because of the following reasons:

$- \sqrt {3}$ is coefficient of $i$ & not $7- \sqrt {3}$

Given number is a difference of a real number and imaginary number & not a sum of a real number and imaginary number.

Find the volume of a regular tetrahedron whose altitude measures 10 cm.

Vlad [161]

The answer is 118 cm³

The volume of tetrahedron (V), where a is its altitude, can be expressed as:
$V= \frac{ a^{3}}{6 \sqrt{2} } =$
$V = \frac{10 ^{3} }{6 \sqrt{2} } = \frac{1000}{6*1.41} = \frac{1000}{8.46} = 118.2 cm^{3}$ ≈ 118 cm³
