Just add them together and you have your answer.
Answer:
Step-by-step explanation:
v = πr²h = π·2²·3.5 = 14π cm³ ≅ 44 cm³
Start with the first sentence, and the definition of the area of a rectangle:
l * w = 36
Rewrite the equation to get
l = 36 / w
or
w = 36 / l
Either one shows the inverse relationship between w and l.
Assuming the last part wants you to write an equation for an x-y graph, the equation would be
y = 36 / x
The expression: sqrt ( 5 x² - 27 x + 10 )
A real number is a square root of a positive number.
x 1/2 = ( 27 +/- sqrt ( 729- 200 )) / 10
x 1/2 = ( 27+/- 23 ) / 10
x 1 = 4/10 = 0.4
x 2 = 50/10 = 5
Answer:
The expression is defined as a real number for:
x ∈ ( - ∞, 0.4 ] ∪ [ 5, + ∞ ).
