Answer:

33.49 mm³

Step-by-step explanation:

The formula of volume of sphere

=  \frac{4}{3} \pi {r}^{3}

The volume of the sphere

=  \frac{4}{3}  \times 3.14 \times  {2}^{3}

=  \frac{100.48}{3}

= 33.4933333...

= 33.49 mm³ (rounded to the nearest hundredth)

can someone help me please? Lines AB and CD are perpendicular to each other. If 1 measures (3x + 3)°, and 2 measures 39°, what i
tester [92]

Answer:

x = 16

Step-by-step explanation:

Angle 2 is equal to 39, which means that Angle 1 has to be 51, since Angles 1 and 2 together is a right angle

3x+3=51

Subtract 3, making it 48

Now do 48 divided by 3, and you get 16

A) Enter the corresponding values on the quadratic formula:
ollegr [7]

The answer is a = 0, b = -5, and c= 39.

<u>Step-by-step explanation</u>:

<u>step 1</u> :

A quadratic equation means that it should have at least one squared term.

<u>step 2</u> :

The standard form is ax² + bx + c = 0.

<u>step 3</u> :

The solution to the quadratic equation is usually written in the form

x = (-b ± √(b2 − 4ac))/(2a)

where a = coefficient of x^2

           b = coefficient of x

          c = constant term

<u>step 4</u> :

The given equation is -5x +32.

∴ The answer is a = coefficient of x^2 = 0

                           b = coefficient of x = -5

                          c = constant term = 39
