Let's use the point-slope formula to write the equation of this line.
The point-slope formula is y - y₁ = m(x - x₁).
In the formula, x₁ and y₁ are points and the m is our slope
Now let's substitute.
y + 2 = -3/2(x - 6).
Notice that I put y + 2 above since y - (-2) means y + 2.
Now distribute the -3/2 through the parentheses.
This gives us -3/2x + 9.
Bring down your y + 2 and we have y + 2 = -3/2x + 9.
To put this in standard form, we need to multiply both
sides by 2 because we can't have any fractions.
This gives us 2y + 4 = -3x + 18.
Now move the +4 to the right by subtracting
4 from each side to get 2y = -3x + 14.
Now move your x term to the right by adding 3x to both sides.
So our final answer reads 3x + 2y = 14.
Answer:From the attached graphic, Half-life = ln (.5) / k
Half-life =.693147 / 0.1142
= 6.0695884413 days
Step-by-step explanation:The value of "k" should be negative and should have units associated with it.
Answer:
7
Step-by-step explanation:
So first you would have to know the formula for the volume of a sphere to solve for the radius. The formula is:
V=4
/3πr3
so now we plug in the variables
1,436=4/3πr3
divide by pi
457.09=4/3r3
divide by 4/3 (multiply by the reciprocal which is 3/4)
342.82=r3
Take the third root to get r by itself
r=6.998 or 7 if you will.
