zvonat [6]3 years ago
6 0

Answer:

Rewrite equation as:

x^2 + 2x +2 =0

a = 1 b = 2 c = 2

x = (-b +- sqr root (b^2 -4ac)) / 2a

x = (-2 +- sqr root (2^2 - 4*1*2) ) / 2

x = (-2 +- sqr root (4  - 8) ) / 2

x = (-2 + sqr root (-4) ) / 2

x = -1 +- i

The formula for the volume sphere is V=4/3pie r^3 what is the formula solved for r?
oksian1 [2.3K]

Answer:

r = \sqrt[3]{\frac{3V}{4 \pi}}

Step-by-step explanation:

From the formula of volume of a sphere we have to isolate "r" on one side of the equation i.e. we have to make "r" the subject of the equation.

V=\frac{4}{3} \pi r^{3}\\\\ \text{Multiplying both sides by 3/4 we get}\\\\\frac{3V}{4} = \pi r^{3}\\\\ \text{Dividing both sides by } \pi \\\\ \frac{3V}{4 \pi} = r^{3}\\\\\text{Takeing cube root of both sides}\\\\\sqrt[3]{\frac{3V}{4 \pi}} = r

Therefore:

r = \sqrt[3]{\frac{3V}{4 \pi}}

How do I solve this ?
Anettt [7]

Answer:

Base is 5/6

Step-by-step explanation:

We calculate the area of a triangle by multiplying height to the base and that divided by two

Let's call the base X

5/36 cm^2 = 1/3 × X ÷ 2 multiply both sides of the equation by 2

2 × 5/36 = 1/3 × X ÷ 2 × 2

5/18 = X/3 now divide both sides by 3

5/18 ÷ 3 = X/3 ÷ 3

X = 5/6
