Find the four arithmetic means between -21 and -36.

lara31 [8.8K]

The numbers given in the problem above are part of an arithmetic sequence with first and sixth terms equal to -21 and -36, respectively. Firstly, calculate for the common difference (d).

d = (-36 - -21) / (6 - 1) = -3

The arithmetic mean is calculated by adding -3 to the term prior to it.

a2 = -21 + -3 = -24 a3 = -24 + -3 = -27
a4 = -27 + -3 = -30 a5 = -30 + -3 = -33

Thus the four arithmetic means are -24, -27, -30, and -33.

A bowl in the shape of a hemisphere has a volume of 144π cubic centimeters. What is the radius of the bowl?

Alla [95]

Answer:

6 = r

Step-by-step explanation:

V = $\frac{2}{3}$ πr³ Use this equation to find the volume of a hemisphere

144π = $\frac{2}{3}$ πr³ Divide both sides by $\frac{2}{3}$ π

216 = r³ Take the cube root of both sides

6 = r
