The number is 30
100%=70 x%=21
Solve for the equation and it gets 30
H(17) = 17
Do you need help with the other 2?
Answer:
$1,605
Step-by-step explanation:
As, 7% of $1,500 is = $105
So, the investment is = Principcal + Interest.
= $1,500 + $105 = $1,605
The slope-intercept form is
y = mx + b,
where m = slope, and b = y-intercept
Now we get the y-intercept and the slope from the graph.
The y-intercept, b, is 4.
To find the slope, start at (-2, 0). Go up 4 and right 2 to point (0, 2). That is a rise of 4 and a run of 2.
m = slope = rise/run = 4/2 = 2
Equation:
y = mx + b
y = 2x + 4
Answer: y = 2x + 4
Answer:
S = √(3V/H)
Step-by-step explanation:
The opposite operation of squaring is <em>taking the square root</em>.
![\boxed{S=\sqrt{\dfrac{3V}{H}}}](https://tex.z-dn.net/?f=%5Cboxed%7BS%3D%5Csqrt%7B%5Cdfrac%7B3V%7D%7BH%7D%7D%7D)

In the more general sense, the inverse operation for raising to a power is raising to the reciprocal of that power. We know that ...
(a^b)^c = a^(bc)
When we want bc=1, we must have c=1/b.
We know that the denominator of a fractional power is the index of the corresponding root:
![\displaystyle x^\frac{1}{n}=\sqrt[n]{x}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x%5E%5Cfrac%7B1%7D%7Bn%7D%3D%5Csqrt%5Bn%5D%7Bx%7D)
For n=2, we don't usually write the index in the root symbol:
![x^{\frac{1}{2}}=\sqrt{x}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D%5Csqrt%7Bx%7D)
In the case of this problem, ...
![(S^2)^{\frac{1}{2}}=\left(\dfrac{3V}{H}\right)^{\frac{1}{2}}\\\\S=\sqrt{\dfrac{3V}{H}}](https://tex.z-dn.net/?f=%28S%5E2%29%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%3D%5Cleft%28%5Cdfrac%7B3V%7D%7BH%7D%5Cright%29%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%5C%5C%5C%5CS%3D%5Csqrt%7B%5Cdfrac%7B3V%7D%7BH%7D%7D)
