the volume v of a tank varies directly with its height h a tank 12 ft High holds 300 cubic feet write an equation relating v &am

Liula [17]

v varies directly with height means

v/h=k were k is a constant

or also h/v=k where k is a constant (this is a different k than previous)

so if h=12 and v=300 then

h/v=12/300=1/25=k

so the relationhip could be h/v=1/25

if you di v/h, then

v/h=300/12=25/1=25=k

so the relationship could be v/h=25

5 (3y — 13) = бу – 2 PLEAse help Need those 2

____ [38]

Answer:

y = 7

Step-by-step explanation:

5(3y - 13) = 6y - 2

5*3y + 5*-13 = 6y - 2

15y - 65 = 6y - 2

15y - 6y = 65 - 2

9y = 63

y = 63/9

y = 7

Check:

5((3*7)-13) = 6*7 - 2

5(21-13) = 42 - 2

5*8 = 40

Please help me Algebra 1

Oduvanchick [21]

Answer:

a. $\sqrt{x^n}$ = $x^\frac{n}{2}$

b. $\sqrt{x^n} = x^\frac{(n-1)}{2}\sqrt{x}$

Step-by-step explanation:

a) When n is even, then it is divisible by 2. Because of this, you can write:

$\sqrt{x^n} = (x^n)^\frac{1}{2}$

$\sqrt{x^n} = x^\frac{n}{2}$

b) When n is odd, then n - 1 is even. This would make it divisible by 2, and there would be a remainder of 1, so we can write:

$\sqrt{x^n} = (x^n^-^1^+^1) ^\frac{1}{2}$

$\sqrt{x^n} = (x^n^-^1$ × $x)^\frac{1}{2}$

$\sqrt{x^n} = x^\frac{(n-1)}{2}$ × $x^\frac{1}{2}$

$\sqrt{x^n} = x^\frac{(n-1)}{2}\sqrt{x}$
