Answer:
b = 125
Step-by-step explanation:
Given a varies directly as ![\sqrt[3]{b}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bb%7D)
then the equation relating them is
a = k ← k is the constant of variation
To find k use the condition a = 3 , b = 64 , then
3 = k![\sqrt[3]{64}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%7D)
= 4k ( divide both sides by 4 )
= k
a = ← equation of variation
When a = 
, then
= ( multiply both sides by 4 to clear the fractions )
15 = 3 ( divide both sides by 3 )
5 = , then
b = 5³ = 125
Answer:
Well theres not question to answer but if your asking how to find the area of a triange you do:
Step-by-step explanation:
1/2×b×h
B=base/length
H=height/width
HL postulate.
Step-by-step explanation:
In the given triangles,
- Angle ADC = Angle BDC ( 90° )
hence, the triangles are congruent by HL postulate .
